Time to reach out to some experts:

History:

Past 3-4 weeks been noticing really bad 3g speeds (no 4g in my area). I can't do anything on 3g. Eventually downloaded SpeedTest and shockingly saw why.

My speeds, on average is 0.04mbps (that is not a typo). My wife's 4S, in the same room gets 0.50-0.60 mbps (which is what I would expect as normal). On occasion, I will get test results > 0.50 but only at odd hours (same location too).

Things tried (that didn't do anything):

Sprint tech support re-provisioned my network.

Sprint cleared my browser cache (pretty sure this has nothing to do with my problem).

Sprint techs took my phone for the evening to run tests. Of course, nothing is wrong.

Downloaded a signal strength app. -76dbm, ASU: 18 (4+ bars shown) From what I googled, this means the signal is good.

Voice is fine, Data is not.

Factory reset my phone.

I looked up my external IP @ 66.87.67.248 and I'm apparently assigned to a location in Kansas. I did a traceroute to google.com and my average hop times are 100-150 over 15 hops. My working theory is if the signal is good it must be how my IP packets are being routed over the network (if indeed, my IP address is in Kansas when I'm in San Diego) causing unnecessary hops and killing my overall speed. I've seen this happen before when my ISP, RoadRunner, had a bad router which was bouncing traffic everywhere effectively messing with data speeds.

I don't know what to do next to help troubleshoot. Sprint says there's no issue with my phone but clearly, there is. I really would like to force a new external IP assignment but dunno how to do that either.

TL;DR; Sprint tech support is useless. Signal looks good. External IP does not.

Welcome to Sprint. No one ever gets good speeds from what I have heard.

Bro I feel your pain.. I'm pretty new to all this so I didn't know how bad Sprint was.. I tried the 3g4g fix that some people say works.. it did nothing for me.. I've tried 10 different modems, 5 different roms, stock, rooted, and unrooted.. nada.. zip..zilch.. Sprint fail. I'm done going to Verizon as soon as I possibly can.. my phone looks like a dial up modem compared to my girls s3.. embarrassing..

[General Questions and Answers] kickofthecat:
I've been trying to find someone interested in helping to update my Zenithink tablet (as mentioned in the title), to Androiod 4.1. I currently have 4.0 ICS, but it seems "glitchy" with program crashes not being uncommon. I've viewed similarly equipped devices running Jelly Bean that seem to run smoothly. I also know that there are custom ROM's that could be used, or modified to increase RAM from 512Mb to 1Gb or more and this wouldn't hurt performance any considering the 1ghz cpu, (that I understand actually normally runs at 800mhz).

My quest for this assistance started a few weeks ago and uincluded reading several threads on xda, but there seemed to be no posts I could find relating to this particular brand of tablet, (or many other brands of tablet). So, I went with what appeared to be the likely location to post on slatedroid. Unfortunately, as can be seen in my posts there in the thread linked to below, there simply wasn't any interest, even though, the tablet I use is very similar to the ZT-282 that has so much content relating to it on that site. The thread can be found on slatedroid with the topic being:

"porting jb to ics based zt-280 z102 and others"

I've hunted around xda trying to find the most likely place to post this topic and this is what I've come up with. If I'm in error by posting here, please feel free to suggest an alternative place.

Thanks!

[General Questions and Answers] mittr:
Just seen an article on armdevices about Chinese e-reader maker Onyx International building a prototype smartphone based on Android with an e-ink display.

Can anyone tell me, or point me in direction of someone who knows what specific technical challenges there may be re-architecting Android to work better with e-ink display? Given e-ink's limitations on screen refresh, colour/video i'm assuming there would be certain elements of the OS that you'd want to optimise?

Thanks
[General Questions and Answers] gagdude:
A much more minimalistic UI, for starters. I saw a video and noticed the homepage was like Metro UI. But Android was not built for E-Ink and I don't see a practical use for an E-Ink phone, so what is the point of Onyx making this phone? My prediction is a complete and utter failure, maybe 100 sales

I wanna know if we could pull an active theme maker out of the Thrill community, we've got a Developer, we just need a Themer & a few other things, maybe a Tweaker, someone to help tweak the ROM a bit and fix the phone, most other communities have this, we need this!:)
[Galaxy Note II Q&A, Help & Troubleshooting] ks-man:
This is pretty strange so I thought I'd check here with people.

I got my new Sprint Note 2 today. When I was at home it connected to my wifi network and worked fine. When I got to work I connected it to our wifi network and the internet won't work. If I turn off wifi internet comes back.

Here's the kicker, I have my old iPhone right next to it connected to the work wifi network and it is connected fine to the internet. This is definitely going through wifi as I no longer have a data plan on that phone.

I checked with our IT admin who said that there is no need to "accept" a device on our wifi network. He also rebooted the network for good measure. After both phones lost the network (from the reboot) and reconnected the same thing happened. No internet from my Note but internet works fine on the iPhone. Restarting my Note doesn't fix the problem.

Any ideas? Thanks.

My network admin created a second wifi network to connect to (I guess our router supported it) and when I connected to the new one I got internet.

Hi, I've got the International version N7100 and experiencing weird wifi problem. I have tried to reset my wifi router and use static IP but it doesn't solve the problem. Btw, the problem is whenever I connect my Note 2 to wifi it would lose connection after a while then messes my router and connection of my PC to router as well. Never had this issue until I brought the Note 2 home a week ago. I had to restart my router and turn off my wifi on Note 2 for everything else to work. My iPad, iPhone and PC are all doing fine when Note 2's wifi is off.
[Galaxy Note II Q&A, Help & Troubleshooting] jetsetwilly:
I used to have terrible problems with my Virgin Superhub which all went away when I changed the security settings to WEP hexidecimal from WPA2-PSK (AES). Laptops and phones would have intermittent connections all the time which a reboot or channel change would sort out but only temporarily. Give it a whirl.
[Galaxy Note II Q&A, Help & Troubleshooting] b1nb1n2012:
I've been experiencing the same problem. It's especially annoying when I try to download big size apps on Google Play ( > 1 gb) because it will stop any moment and i will have to re-download it over and over again. It never happens when I connect to school wifi but it just happens when I connect to my wifi at home. Weird. Nothing is wrong with my wifi at all because my other computer is always connected 24/7 without any problem.

Also having Wifi issues with GN2 from Sprint

I got the GN2 on it's release date (this past Thursday) through Sprint. Got it home got set up, connected...everything worked beautifully.

After a couple of hours, downloading apps etc. I noticed it had stalled. Turned off WiFI and used the network to finish. Turned back on WiFi and Voila, action again, but a few hours later it stalled.

I first made sure all of my settings were in agreement. No sleep mode or anything like that was enabled. No power saver either.

Couple hours goes by, WiFi connectivity stalls (even though it shows a full signal) I contacted TWC and made sure it wasn't the modem/router. I changed the wifi channel, tinked with the bandwidth... everything worked...an hour later it stalled. Called Sprint they said I had a dud, took it back, exchanged it, got the new one... SAME ISSUES. YEsterday I connected to my Church network HOPING it was an issue at home, but not so. After an hour on the network it stalled.

Contacted Samsung today and they have had no complaints according to them so i said I'm happy to be the first... If anyone finds a fix please let me know.

PD
[Galaxy Note II Q&A, Help & Troubleshooting] Stegar2108:
Do you have any solution yet? I have the same issues with 2 different networks. I already contacted Samsung, but they only say I should do a reset of my device and read the setup instuctions for wifi. I'm still in contact with Samsung and hardly try to get a solution.

Stay tuned, I'll post any news I can get.

Same issue here. Connect wifi and I'm able to hold connection for as little as minutes at times. Turn back on 4G and I'm fine. If I re enable wifi straight after it works intermittently. This is true of both my home and office wifi. So I'm lead to believe it's the phone.

Almost the same thing here. everytime I go out of my home and comeback the wifi network seems to work but no internet access. I have to stop and restart wifi then it works.

[Galaxy Note II Q&A, Help & Troubleshooting] sonicthoughts:
Same issue - connects for about 30 seconds

I've tried on different routers. Other devices (iphone, ipad, S3, etc.) all work fine. Sees the wifi network. connects, then disconnects and TURNS OFF WIFI. I can't figure out how to go to service mode to see if this is a timer issue. I've tried on both G and N networks. using a verizon fios, actionteck router (and netgear). Also, will not remember the password credentials. :ptried router reboot and fidling, etc. Driving me nuts. any suggestions ???

didnt work for me, the only solution was to overwrite "wifi" folder.
[Galaxy Note II Q&A, Help & Troubleshooting] jdnyc:
I had these issues. Had my device replaced and, after reinstalling all of my apps, the same problems showed up. The fix for me was to remove a few apps that toggled my wifi setting. Though I didn't try combinations of apps to isolate the offender, removing SwitchPro seemed to do the trick.

If you have tried the other solutions in this thread, try removing any apps that toggle (or have control over) your wifi connection.

That slow wifi speed problem is in Samsung stock kernel! After changing to Perseus kernel that problem disappeared. And in other roms, that don't use Samsung kernel,like cm10 etc works wifi fine. So problem is in kernel. But now I'm back in sock v12, but I flashed oldest kernel in Omega files stock kernel list, and now both wifi and Allshare Cast Dongle working fine.

Is that normal to use older stock kernel?

EXACTLY same problem with my Note 2, and like I said in previous comment, that this problem is in Samsung stock kernel, and after flashing Perseus kernel that problem disappeared. But Allshare Cast Dongle don't work with custom kernels, so now I flashed oldest stock kernel and wifi and Allshare dongle works fine. So we must wait Samsung update, or use older kernel, or custom kernel.

4.1.2 broke my wifi

I noticed that my wifi stopped working after upgrading to 4.1.2. I read here about the fix to root it and install the 4.1.1 wifi folder. That did the trick for me.

I tried three different wifi router/access points. Two of them new. I tried it with static ip addresses or with DHCP servers not in the router. Had my note 2 factory reseted.

Tried it in different networks. Even at McDonalds with free wifi.

Always the same error: Tried to connect and than "acquiring IP Address", which always failed.

I already had a RMA number from Samsung for my Note2 only 10 days old, but who told me I need to wait up to 8 weeks to get it back.

ANYONE WITH THIS ERROR, find here in this Thread the post of the person who posted the fix.

Thank you, sir!!!
[Galaxy Note II Q&A, Help & Troubleshooting] Atsco:
That folder changing fix didn't help me, but me and Montix have a different problem: slow speed after coming back from deep sleep. And if you, Montix, don't want flash kernels, then is another fix for that problem. In Play Market is app called "deep sleep battery saver". That app turns every time, when phone goes to sleep wifi off, and turns if back on, when you start using phone again. You don't have to do wifi restart every time by your self. And if you didn't noticed, wifi restart helps helps with that problem. But still, that isn't normal, that we have to restart wifi every time, when we use phone and I hope that Samsung already knows about this problem, and update with fix is coming soon.

---------- Post added at 11:48 PM ---------- Previous post was at 11:18 PM ----------

But good thing with that problem is that about week ago I learned flash roms and kernels, and started use that forum. And one thing, that I want say is that this Omega ROM is best of the best!!!

Now I almost don't sleep (because that I didn't want to start flashing:rolleyes:) ,flashing and reading all the time, so I tried many, many roms, but returned back to Omega every time.

And sorry, if my English is not so good, but thats a first time in many, many years, when I have to write in English. Probably I use to write in English last time in school, 25 years ago:eek: So hey everybody!
[Galaxy Note II Q&A, Help & Troubleshooting] montix:
Great explanation and good enough english for me Hahahaha!!!

I also think that we must a Samsung solution,but i don't understand why other users don,'t have this issue...The hardware is the same...This is only thing worring me,becasuse if i go to technical service i know they only probe the antenna capability and this is fine cause Note can prefectly connects ;)

N7100 Wifi connect issue

Worked like a charm! Is there a way to make this setting permanent as it resets after each reboot?

Thanks,
[Galaxy Note II Q&A, Help & Troubleshooting] karlada:
No and try this btw

First of all, No u cant make this permanent ,You have to do this after each reboot or shutdown...

Anyway to ease things a little... instead of typing all of these numbers, try pressing this *#0011#... and then same procedure... menu key wifi and turn off wifi powersave ... tell me if this works :D

---------- Post added at 06:39 PM ---------- Previous post was at 06:34 PM ----------

Did you copy the "wifi" folder into your "etc" folder using rootexplorer?

second try turning off wifi powersave mode by pressing in your dialer *#0011# -->menu key --> wifi -->click the on button that sais next to it "wifi power save mode" if that didnt do the trick let me know :)

Hi first time poster here!

I'm suffering the same problems as others concerning drastic drop in speeds via wifi on the Note 2 since the 4.1.2 update...

I have tried everything but nothing works... I have to keep turning wifi off then back on to get full speeds and that lasts for probably 30 minutes till the speeds drop from 30/40mbps to 5/6/7mbps if i am lucky! but the uploads speeds stay the same around the 3/4mbps mark :confused:

Is this a bug that Samsung know about? i hope it's going to get fixed as i use wifi alot on my phone in the house and turning it off and on seriously gets annoying after a while!
[Galaxy Note II Q&A, Help & Troubleshooting] asymetric:
I'm sure they know something about this bull sheet but they don't want to deal with it. Now I think it's a hardware issue because after got full wiped and flashed the first stock 4.1.1 firmware, wifi doesn't work anymore. I agree with you concerning uploading because tethering is working fine.

I hope Samsung do address the issue and release some patch that fixes it, as turning wifi off and on will not be acceptable for me!!
[Galaxy Note II Q&A, Help & Troubleshooting] shimarayn:
Solved (for me at least)

Hi again all,

So I was having this issue for a few days and it was driving me crazy as I was using the *#0011# fix which was pointed out to me. ( Read back over the posts to find the full details) Eventually after trying loads of different ROMs and Kernels I managed to sort it out. I am Running AllianceROM for N7100 and have flashed the Stock Kernel N7100XXDLJ2. Don't know if it will fix anyones problem but flashing that kernel sorted mine. All the best..
[Galaxy Note II Q&A, Help & Troubleshooting] Atsco:
Here, in this forum, people talking about different wifi issues, but you, me, and many, many others are talking about exactly the same problem: slow speed, after phone comes back from deep sleep. Problem started after 4.1.2 update. And like I said here before, that problem is in Samsung kernel. I flashed Omega v12 rom, and problem didn't disappeared, but after changing kernel, problem is gone!

Omega rom is based to original Samsung rom, so thats why problem didn't disappeared at first. And only working STOCK kernel is OXXDLJ2. Newest kernels coming all with that problem.

And I have to use stock kernel, because Allshare Cast Dongle works only with stock kernels.

So I hope to, that they know about that problem, and fix is coming, because I don't like the idea, that I must use very old kernel, forced to flashing etc.

Fixed with Static IP

Hey guys I fixed my problem thanks to the gentlemen above this post for pointing me in the direction of DHCP. I assigned my phone a static address and can now surf the net with ease, when before I could not even ping the gateway from my phone.

Go into Settings -> WIFI -> long tap the name of your wireless network -> modify network config -> press back to hide the keyboard.

Change IP address to static, and put in a free IP address on your network, and in gateway put in the IP address of your router.

Should be good too go now.

Also you may wish to reserve the address you give the phone as a static IP in your router to prevent it from handing it out to another device via DHCP.

Cheers,

Hi Guys,

I think I found kind of a workaround for me. If it does not connect (Obtaining IP address...), I will turn on an Airplane mode. Then I will turn it off and WiFi will connect perfectly straight away!

Please try it and don't forget to provide a feedback! :good:

P.S.: To turn on an Airplane mode - hold Power button then choose an Airplane mode. Repeat, to turn it off. :cowboy:
