This is getting weird. As I mentioned in the original post, I intended to measure WiFi transfer speed, not internet speed. But since I have done it on a fast network at my work (university), I thought I might give an internet test a try.

Speedtest.net app shows speeds around 17-19 Mbps, which is about 2.3 Mbytes per second. This is over 4 times faster than my local download speed. This is rather unexpected, and unless speedtest.net is lying, there is an issue with our local transfers.

I believe speedtest.net streams down some data and measures it as it arrives. Perhaps streaming is done in a different way than downloading a big file? Or perhaps downloading requires further processing - storing in local storage, which might slow things down. I have just realized that I was actually opening a 50-Mb web page in the browser. This might be the real reason for much slower speeds of the tablet. I guess I would have to done the test differently, downloading a file directly into storage, though this would still be slowed down by the lack of processing power.

I have edited the original post to include these comments.

PS: At work, my wireless laptop shows a very stable 20 Mbps, and my desktop, which is wired, shows speeds varying widely from 50 to 500 Mbps.

PS2: I tried speedtest.net on the tablet again, standing directly under the WiFi repeater. This gives speeds almost 20 Mbps. I think our WiFi network is limited to 20 Mbps.

@ Felisek

You may try with WiFi File Explorer PRO. It seems there is a bottleneck somewhere in your test environment. This is just an idea.
[Asus  Eee Pad Transformer Prime] Felisek:
Brilliant! When uploading files from my wired desktop to the tablet directly via WiFi file explorer I get speeds of about 2 Mbytes per second, which is the limit of our WiFi network at work. You are absolutely right, opening a text file in chrome was a bottleneck, the actual transfer speed is much faster than that. Actually, I don't know how fast as the network is limited. I will try it later at home and see how fast I can go and how it depends on the distance from the router.
[Asus  Eee Pad Transformer Prime] chogardjr:
I decided to get the round flimsy tape measure out and do an actual distance test.

So this is standing 150ft exactly from router, going through a LCD TV, a metal front door. I'm standing in the middle of the street for this.

The red one is me.

Yeah there is a slow down once you get away but I can live with this.

[Asus  Eee Pad Transformer Prime] phat_11:
Boy I wish I had that kind of performance. At the deep end of my garden, which is roughly 50ft away (if not any close) from the router my signal is between -80 and -90 and the speedtest result is a total fail. I am running a 32gb C10KAS Prime, with the latest OTAs on it.

I am seriously considering on returning the item, especially if there Primes with better results out there :s. Other than that I love all about the tablet.

EDIT: I just tested on a hotspot at work. When the signal strength is between -60db and -70db, I get a perfect connection (maxed out actually at 4mbps). However when the signal is between -70db and -80db (or worse) the speedtest varies between 0,40 mbps and 0,90 mbps. That's sad... :( What do you guys think?
[Asus  Eee Pad Transformer Prime] chogardjr:
If you can make sure the serial# starts with C20. That's the one I've got and from what I've been reading no one is having issues with these. GPS is still no good but who needs that anyway.

[Asus  Eee Pad Transformer Prime] phat_11:
If I find no other solution during the following 2 weeks, I think I'll simply return and wait that these serial numbers appear over here. I preordered in December and got the tablet this past Friday and I am not even sure that the thing is available at the store yet (I saw it only on 64gb model without the dock). I'll try to see what serial number the display model has. In any case, thanks for the reply pal :)
[Asus  Eee Pad Transformer Prime] phat_11:
by the way, just to be on the safe side of things, I tested the device on my way back from work in two other open wifi areas with similar results, once the signal drops under a certain level (-70 or worse) the speed gets awful. Even in the worst case scénario, it is still possible to surf, or use gtalk but it's quite laggy. streaming on youtube is not possible either. Once I arrived home and encouraged by chogardjr test on quite distance, i too the prime in my garden again to see if there is an improvement but to no avail. It's the same old story unfortunately :( The GPS tough did a much better job while on outdoors this second time around, it took 10 secs to find sats and got 4 or 5 in use soon after for an accuracy of 96ft. I could really live without the gps but the wifi is quite important, and even at home its still passable, i was hoping to use the tablet everywhere (like all of us I am guessing :)). I will try to go to the store and reason with the guys there. Now i am fearing to have to wait an eternity for a replacement or even worse having some other issue like the screen or battery life with the new unit:(.
[Asus  Eee Pad Transformer Prime] phat_11:
hey there, i just had a replacement for my prime. It's a C20KAS and i believe even though it feels a bit stronger with the wifi in general, i don't think it's as powerful as I would have imagined. I am nowhere near the performance that chorgardjr registered at 150ft but I kinda doubled my acceptable speed in the middle of my garden which is roughly around 50 feet. In general, the signal strenght is more stable around -60 db when far from router, and the speed is not decreasing more than half so surfing or streaming videos is possible. I will definitely check around on different networks to see how it works since my connection at home is not cutting edge either.

On a more positive note on the exchange that I am definitely happier with the new dock. The keys are much better on this one and typing is a real pleasure with this keyboard. The charger is silent also. not that i care much about it but the gps works much faster on outdoors (still nothing on indoors though).

With all these rumors that asus is on the verge finding a permanent hardware solution to improve wifi/BT/GPS, i am just fearing that by deciding on keeping this one, I'll miss the opportunity of having the "perfect" tablet. Will asus provide us earlier users an opportunity to improve our units as well or just leave us be? It's a great tablet on its own right, but it would have been a killer if it could have a longer range.
[Asus  Eee Pad Transformer Prime] buxtahuda:
150 feet? I call some kind of BS on that distance... I want his Prime :mad:

:p But really, my Prime hits 50-70 feet depending on the router and is still able to stream my music; YouTube becomes inoperable at about 40-45 depending on the environment.

Glad you're happy with the C2, my C1's been a dream aside from the known issues (most of which other than GPS only seem to happen here and there on different updates). And oh dear how the dock completes this thing! I had the Prime a month before finally landing one from Amazon (same place) and I still use the touchscreen for much that I do, but the keyboard is irreplaceable for how useful it is.

On to your question, if an actual hardware fix is in the works (other than repositioning the pogopins or whatever was thought earlier on) then you could send your Prime in to have it done.

However, you could just refund and piddle around for a bit and then get a brand new unit, never opened, that works like you (scratch that, ASUS) feels it should. Just depends. But if you're willing to wait, I'd go on and wait to see what the rest of the year holds.

Me? I love my Prime and can't even consider going back to waiting on some tablet tech to catch my attention. This is my first tablet after waiting for forever to see something as promising as my single-core phone appeared to me.
[Asus  Eee Pad Transformer Prime] BarryH_GEG:
Demandarin and I are fighting in another thread (surprise) about this very issue and I just dredged this up. It talks about the Prime's susceptibility to interference and how performance is impacted by orientation so there's lots of things that could cause each of you to achieve different results. Enjoy.
[Asus  Eee Pad Transformer Prime] phat_11:
I feel the same way bud. I just can't even possibly go through giving up this baby for a refund and wait God knows how long for a better unit (I mean technically revised by Asus, which is a shroud of rumour and nothing more at the moment). It's a great gadget. It just bums me that you can't achieve an acceptable performance in any given scenario. I will still run my test at some point today at the office space and some other wifi areas. But I kinda have the feeling it will still be a bit disappointing on that level.

I think I'm getting more or less the same results with your unit, but I still have the feeling that the C20KAS is reacting better than the previous one. At home, I can say that I have no more blind spots. In the garden, it is true that nothing goes at the deep end (which is to my guessing around 70 to 80 feet from the router, 100 tops) but the unit reacts better halfway.

As for Asus getting the unit for a repair, if they ever announce or make anything such, I really don't mind to know that the unit was opened for improvements at some point. I hope that I'll never have to resell Prime so I really don't mind. I am just fearing that they do the improvements without the knowledge of the general public, and we early buyers find ourselves with nothing in our hands. Or will they ever come clean on this issue at all. And are we sure that even if they come clean, announce that they made modifications, will they offer to first users the possibility to send it back for improvements? More and more wondering.

That's an interesting point of view. Which I believe it was asked numerous times but, can anyone in the meantime explain how come that, no matter how low the signal or how far you are from the router, the upload speed is rock solid. How is this possible?
[Asus  Eee Pad Transformer Prime] drvsbsm:
Not for me man If I'm within 20 feet of my router I get between 15-18mb/s down 1-2mb/s up. I see everyone else is getting great upload speeds and thinking why the hell is mine so slow with upload? I have Cable Broadband Road Runner by the way. Thats in my Computer Room downstairs in bi-level home. If I go upstairs I get 8-11mb/s down same 2mb/s up if I go back to the furthest room in the house which is bi-level, I go upstairs through the hall all the way to the back bedroom about 60+ feet. I get 3-5mb/s down really low upload less than 1mb/s. All this data is from Speedtest app BTW.

I do understand the original post was not about speedtest app though it was a post about actual file downloading speed. Haven't tried yet, I will tomorrow because I have until the 5th to send mine back. GPS don't work but don't care really.

I just wish I had constant WiFi like my Touchpad, In the furthest backroom it will get 16mb/s download on speedtest, while the gets ATP 3-5mb/s. Model C1OKxxxxxxx whatever.
[Asus  Eee Pad Transformer Prime] phat_11:
yeah constant wifi will be swell :) let's keep up the hope alive bud :) one way or another, some soft or hard tweak in the near future

by the way the bedroom at home is located one level below the router, and when I get to the exact opposite position of the router (so one level below plus a distance of 20 ft from the router) I still get full speed with the new device. The first one I had was losing already some dl when in the bedroom but now it's ok. Or it's just me dreaming or somethin' :eek:

But in no way at 60 ft i get readings like yours (out of a max 12mpbs, I am getting a max speed of 1mpbs)
[Asus  Eee Pad Transformer Prime] phat_11:
by the way, this test seems to concur with our observations about distance from the router http://blogs.computerworld.com/19602/transformer_prime_wifi_performance

he is not getting into a lot of details, but aside from some details, I kinda think it's the same issues I'm having.
[Asus  Eee Pad Transformer Prime] buxtahuda:
I believe I remember someone saying it has something to do with the fact that upload packets are smaller and simpler than download packets. It seemed a reasonable thought to me.
[Asus  Eee Pad Transformer Prime] sontin:
I think the problem is the dual antenne design. When i cover my left upperside (asus logo) then i get much better download/upload speed. But my signal will be lower. With booth antennes working my signal is better but my speed is much lower.

So there is a load balancing problem between the antennes which reduces the speed...
[Asus  Eee Pad Transformer Prime] phat_11:
Interesting... And do you think this can be fixed via software solution or it's a hardware issue?
[Asus  Eee Pad Transformer Prime] BarryH_GEG:
To me, and me only, what Anand's comments and tests show is that the Prime is highly susceptible to interference because, in addition to external interference, there's some degree of internal interference caused by the metal back cover. If you’re in a pristine environment like the one Anand had to create you'll get better performance than someone in an airport or hotel with different APs all broadcasting at the same time. Bottom line is unless you live in a single family home and only use your Prime there you'll be at the mercy of an environment you can't control to determine what type of signal your Prime will receive.

When you think about it, other tablets receive their best and strongest signals through their plastic back covers and their antennas are optimized for that. The Prime's antennas are optimized to face forward through the glass front panel. The second antenna was Asus' attempt to boost the forward signal to compensate for up to a 50% signal deficit caused by the metal back cover. If Asus’ engineers somehow figured out how to get RF signals cleanly through metal their wasting their time building tablets. Apple’s couldn’t and in spite of placing the antenna behind perforations in the speaker grate the iPad2 still suffers a 10-15% Wi-Fi degradation over the iPad1. Twice the forward signal can't make up for the lack of a 360 degree signal source like other tablets have. Especially when it comes to maintaining the continuity of a signal. There are plenty of YouTube videos showing how the Prime performs differently if its back or front is facing the router. Assuming comparisons being made are between comparably performing Prime’s, the differences people are experiencing are environmental and/or based on its positioning to the router.

We know there are "good" and "bad" Prime's based on peoples experiences. Anand's first Prime was a "bad" one and they sent him a second Prime that they tested beforehand. So it's pretty safe to assume it was a "good" Prime. That said, I think his experiences pretty well reflect what's going on with the Prime Wi-Fi wise. The TF101 he was using as a comparison performed like every other tablet and had none of the sensitivities the Prime did. What's different? It all comes down to the metal back cover and the design employed to compensate for it.
[Asus  Eee Pad Transformer Prime] phat_11:
Yeah but during the primes qualified as "bad" ones are litterally awful. No stable connection whatsoever, terrible speed and signal both at close range or far from router. The problem I encounter is only far from router. And when is it ok to say that we have a "bad" copy?
[Asus  Eee Pad Transformer Prime] BarryH_GEG:
That's what makes these performance discussions so screwy. Knowing there's issues between devices it's hard to tell whether it's the device itself or the environment it's being tested in. My guess is that the "fix" Asus is coming up with is a new simpler antenna design that ****-cans the pogo pins and will make all devices perform the same way. At least with that in place there can be some meaningful discussion about how to get the most out the Prime's Wi-Fi. But, let's face it, Wi-Fi performance is so individual based on environment, age/brand of router, and ISP, that there's always going to be "mine's fantastic" and "mine sucks" posts. For example, the SGS2 hates D-Link routers. It took months before a pattern was found so that people knew that. So in the end, people either had to dump the phone or replace their router to get decent Wi-Fi.
[Asus  Eee Pad Transformer Prime] Justin_Thyme:
:eek:

Another WiFi thread......:o

Throughput with a decent connection has never been an issue for most. Now move that laptop to where it gets half bars and repeat a throughput test on both from the same location...It is then that things will come to light. :cool:

Ive beat it every which way and in the end the WiFi connection is less than desirable. Real question is does it have an affect on your use. At home I never have issues even in the weakest points. Hit the road and stay in a hotel and its luck of the draw on whether you get close enough to a WAP to connect or not . Just had this issue recently. Nice 4* hotel and connected with Crackberry, Laptop with about half bars and had no issues. Prime didnt even indentify the network. :(

Its not an issue with the likes of the local coffee shop as they are generally small and one usually has less than 20ft distance between themselves and the WAP. Go to an airport and you have to wander around until you find a sweet spot which may be on the other side of the terminal from where your flight is to depart. Hmmmm go way over there or sit here with my laptop......Not a hard decision to make......
[Asus  Eee Pad Transformer Prime] buxtahuda:
So, they figured out what, but how about why?

I realize different chips, manufacturers, etc are going to yield different results, but isn't the underlying technology the same? Why would one brand of signal work better than another?

I've been playing with computers since before I could speak well, but that's the majority of what I do: play. As I've gotten older I've taken much more interest into these kinds of things, and deal with quite a bit of networking both personally and professionally, but I still don't really know the finer details of much. I can just make it work, and usually have to use Google to achieve that :D
[Asus  Eee Pad Transformer Prime] phat_11:
and not only that, but will they do something about it? and if they do, will this only affect the newly manufactured ones, or will they lend a help on people who bought the thing in the first place? that's a helluva lot of questions imho :) still hoping that asus will come clean about all this rumours and mak things straight to satisfy everybody :)

oh man, you just made my worst nightmare come true. This distance thing is really pissing me of. I'll have the opportunity to check in a hotel the quality of reception of the device pretty soon, but by that time I will not have the chance of returning this babe for a refund anymore :( but I really love it anyway. like you say, in a closed space like at home or some cafe things are working pretty smoothly. At work, there is an open network I can connect to, and the signal varies pretty much on where i am standing, and on some places the connection is pretty strong, but like in your example, unfortunately it's not the places i usually work at :s. I've been able at least to confirm that this 2nd device i'm having is reacting better than the first one. It is as i it was fighting to get a better connection when I am far from a router (the dl speed starts from very low speed and getting faster at the end) and the surfing is like having a moderately acceptable connection. But this idea of Asus modifying the specs of the next line of production is killing me.

At the end of the day, I love the tablet, but i could really use a better connection at all case scenarios. Is it worth the wait fo the new 700t and it's full hd resolution with "optimised" connectivity. Don't think so, cause by that time there will be windows 8 tablets that will get also our attention. And the Prime looks for now, even with its flaws the tablet worth having right now.

edit: weird thing about the wifi and gps, sunny day and cloudless day in Brussels, tried the gps outdoors again with no luck at all, no nothing for more than 10 minutes... and weirdly enough the range of the wifi is less... wtf?
[Galaxy S II Accessories] pierreluc102:
Yep, my phone is melted down. Totaly busted. Went red, then melted. Really ****ing awesome.

Got a picture?
[Galaxy S II Accessories] Ccollado10:
That happened to a friend of mine... Have you got pictures?
[Galaxy S II Accessories] pierreluc102:
Lol, well. Let's put it this way, my picture taking device is now debris. I'll try and take a picture with a friends camera.
[Galaxy S II Accessories] ChrisTough:
I only have 2000 mAh and my phone lasts for 2 days with moderate use running on stock is it just an average?
[Galaxy S II Accessories] blue265:
Wow that sucks. Any idea what brand or was it a non-brand item? If you have any details maybe post them so people stay away
[Galaxy S II Accessories] taylormoonz:
wow, This was an original bettery?
[Galaxy S II Accessories] ogblaz:
Man that sucks, please link to the item and some picture would be nice, so nobody else`s phone suffers the same fate :(
[Galaxy S II Accessories] sammyx:
is it this battery?

:eek::confused:
[Galaxy S II Accessories] pewpewbangbang:
Thats why you shouldn't skimp out when it comes to batteries.
[Galaxy S II Accessories] TheWizardbc:
I have the same battery, but I'm using it rarely, the batterylife is not better than the original, and it will not fit my phone holder in the car :).

But you get a better grip on the phone with that backcover.
[Galaxy S II Accessories] sammyx:
OK, that mean it is not that melted battery from @pierreluc102 post:confused::D

@ pierreluc102 finally tell us exactly name of battery or make picture
[Galaxy S II Accessories] pierreluc102:
Cant post pictures yet, nor can post links, my friend is coming home tonight to take pictures for insurance purposes. I'll post them tonight or tomorow morning, and yes, sammyx had the very same picture the eBay battery had for image, and it is the very battery that melted my phone. 3500mah!

BTW, the acid that came out of the battery burned my floor and my cloths!

Edit: Not only my battery, but my cell phone is melted also!
[Galaxy S II Accessories] wezza1979:
the battery you have in that picture is the exact same one ive had in the past, i never experienced any issues other than after approx 75 charges the battery was down to around 75% capacity, i agree with thewizard you get a much better grip with it on. it could just have been a random faulty battery but it definitely sucks that it screwed the phone up. Ive never come across a perfect solution for upgraded batteries, i went from the above mentioned to the gold 2000 mah battery and to be honest was no better than the original but cost me £10 to find out lol

if anyone knows of any better alternatives be sure to give me a shout
[Galaxy S II Accessories] kmaximax:
Yeah the OFFICIAL 2000mah battery from Samsung :)
[Galaxy S II Accessories] beston94:
Either get(or should have gotten) the anker battery or the mugen 3600 battery. When it comes to a £500 device, then spending £10 or £70 is more than suitable.

Have a good day.

PS: Really sorry about your device..:(
[Galaxy S II Accessories] ekimnal:
i was so close to buying this batter just now

thanks for the heads up

and im sorry for your loss
[Galaxy S II Accessories] marvi0:
Av been using the anker one that comes with the charger so far so good.
[Galaxy S II Accessories] pjonezki:
iv been using the 3500battery for a few weeks now in some extreme conditions and haven't had any problems.

Im feeling a bit worried now took me a while to save up for my s2.
[Galaxy S II Accessories] boombotz401:
Never buy these cheap battery's..only buy from mugen seido or anker all others are junk and have much less capacity then advertised
