I also have a WiFi issue with my Tab Pro 8.4 will connect and then promptly drop connection. I exchanged unit at Best Buy and hoped problem solved..NOT.....this one does the same so disappointed.. I put my iPad air and lgg2 same place only tab dropped connection. I have Time warner (RoadRunner) 50MBPS..every other wireless device in my house runs perfectly.. Don't know what to do?? Can't return its mine now.

I use a Linksys WRT54GS in the house (Time Warner 20 Meg service) ....went to use a friends fios wifi and its performance is now the same as the nexus 7 Gen 2.

Seems that my issue is with the well liked Linksys wireless router....it has the latest firmware as well..

So the big questions is what routers are you guys running that shows issues? Which router is showing no problems?

Thanks!

I'm actually on an ASUS router here. Everything else works well with it and since changing hand placement, the tab has been much better, though I'm still seeing that the wifi range isn't as good as other items in the house.

My 8.4 isn't suffering any wifi problems, even when holding it on the bottom left. On a realllyyy old Netgear router Model WPN824v2.

I've been using my tab in class haven't noticed any issues with the campus wifi.

Imho The reason for all the wifi issues dealing with range is the cheap antenna and connection inside. Hardware flaw.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Q&A, Help & Trouble] cloud71:
I happen to look in the manual, and this is what I found, I'm assuming that it's referring to holding in it in landscape mode, when it says that the antenna is at the top.

Either way it's saying don't cover it up.

Boils down to low end antenna

Took the back off today, was looking at it. The thing is is that theres really nothing that you can do that won't void warrenty or damage the tab.

They could have placed antenna some place else but they didnt.

I was going to take some good quality closeups but I didn't have my camera atm.

If I can get around to it, I'm going to do a youtube video of the disassembly.

Not sure when I'll have the time though

My Fix!

MY FIX.....

Never had range issues like some have notice, but my speed was always down 25% to 40% on both my and wife's Samsung Galaxy Tab Pro 8.4.

Decided to do a hard boot on both my modem and router so everything was reset to defalt on the WRT54GS Linksys G router. Using Time Warner cable Cisco router. (turbo plan).

I am happy to report that speed is now the same on both 8.4's and matches my laptop and other devices in speed...the noticeable lag on packets is also gone when using speedtest.net

BEFORE: Download: 15.23 to 11.16 AFTER: 18.88 to 22.65

BEFORE: Upload: 1.34 to 2.02 AFTER: 2.95 to 3.31

So if you have a speed issue I highly recommend that you do a hard boot on both your modem and router before replacing anything! On Linksys G router all you need to do is with the router powered on push in the reset button for about 10 seconds until the front WLAN starts flashing then release it...then turn off the router for about 30 seconds and turn back on. Do the same for the Modem as there is a reset button on it as well...You will then need to reset your security by logging into your router and enter 192.168.1.1 as the web address. Your defalt user/password is: admin Make sure you change both it and the "Administration" password as anyone can get in there and change your settings. While you are in Administration screen make sure you click the "Enable" Wireless Access Web as the defalt is Disabled! Next, In the Wireless setting screen use the higher security WPA2 Personal setting and enter your new or old "WPA Shared Key" as this is the ID you will need to change on all your devices to log on to your internet. You may need to reboot your windows computers and reset new home connections, did not have to do this on the tablets.

Hope this helps some of you!

no wifi issue since samsung shop flashed stock rom again

hi there, i'm new to this forum and i'm from austria so my english is crap, sorry. to the issue: i had the same problem with my new galaxy tab pro 8.4 wifi (low wifi connection, wifi-spot-search problems and ongoing lost of wifi connections) and brought it to an samsung shop. i got it back today and they flashed the original samsung stock rom again. since than i have no wifi issues at all. it's now even faster than my ipad 2 at wifi :p so maybe there's hope that it's an software issue :victory:

wifi on tab pro 8.4 very poor

Hi yes my wifi on tab pro 8.4 is terrible less than 12meg at 5 metres from router, no better on the companies router or on my neighbours router. My old sony my 16th shone connects at 72 meg at 20mtre range . I have tried two nexus 10 tablets both performed the same as the tab pro. I am fairly sure it's a kit kat 4.4.2 issue as the nexus 10s were on until they updated to kkit with connection at 20meg at 10 metre range on jellybean 4.2.2 . Tab came supplied with kit kat and was slow out of the box.

Great disappointment I returned the first nexus 10 for a replacement second one of till kit kat update returned for a refund.

I think the tab pro will have to go back to John Lewis as the wifi is slow and very short range.

When I called samsung about the nexus 10s they said kit kat was defective and I should have disabled auto updates!!

Any ideas as to what I can do. I love the feel and looks of the tab pro. 4 and the screen is amazing to see and use.

I am sadly thinking the apple route is the way to go or maybe get a cheap older model of android tablet that is stuck on jellybean.

Help!!
[Galaxy Tab Pro 12.2, 10.1, 8.4 Q&A, Help & Trouble] animedreamer240:
I thought that my Tab Pro 8.4 had terrible wifi issues. It would disconnect about 1-3 times every hour. My previous tablet, the Galaxy Note 10.1 (2012 edition), did not have these issues, and my laptop would stay connected even when the Tab Pro did not. However, after replacing my old modem with a new one (Motorola Surfboard), the wifi issues just...disappeared. And the wifi download/upload speed is roughly the same for my tablet and laptop. Now I'm thinking that the old modem was partly to blame. I can't explain why only the Tab Pro was affected before, but it's all good now...
[Galaxy Tab Pro 12.2, 10.1, 8.4 Q&A, Help & Trouble] dorpmuller:
Well, with me being a radio man since the 70's, (I'm probably the oldest one on XDA!) here's my take on it.

Since the antenna is in the worst area, bottom left in portrait like everyone says, it gets detuned by the capacitance in your hand when the device is held in that spot. Detuning an antenna, especially one that runs full duplex, (TX and RX at the same time) will greatly degrade signal strength. That's why all these troubles. Only solution is hold the tab in another spot. The engineer that did this design must've been hallucinating when he/she decided on a bottom left location, especially since most of us are right handed and would hold the tab right where the antenna is. What a bummer. :( Added to this is the fact that wifi is very low power.

Like it or not, that little foil that is used for the antenna is designed and tuned for the specific range of frequencies that it's supposed to cover, so mucking around with it hardware-wise will make things worse.

Bet you folks that are lefties or using the tab in landscape aren't having any wifi issues at all!

I really don't notice wifi issue either, I have a 6mb down and 1 or 2 mb up frontier.

I do see a drop on the graph when using an app that show wifi strenth, when holding that corner though

so overall, it's not bothering me, if I download or up load something big like 100mb or bigger like game data I usually set tab down while it's doing that anyway.

with respect to the Tab Pro WiFi issues, quite a few people are saying the new "NF3" firmware fixes it.

that said, even on the older firmwares it only seems to be an issue if you hold the tab in the bottom left hand corner (when viewed in portrait mode)

I have just returned this tablet to the store and asked my money back. The WiFi problem is unacceptable to me.

When I hold the tablet the way you are supposed to hold it when you are right handed, the WiFi signal drops significantly. One floor up from where the router is placed, my iPhone 4 from 2010 was able to reach a 20Mbps download speed whereas the Tab Pro only was able to reach 0.86Mbps.

When you are a multi-billion company it is literally beyond me that you have the courage to release a flawed product like this. No Samsung product for me anymore in the foreseeable future.

WiFi Settings/Scan Network Not Available From Sleep to Wake

My WiFi connection is fine, but at random times, I am unable to access the WiFi setting/scan for available network from sleep. In other words, had the screen off, then wake it an hour later; the WiFi icon disappeared, but WiFi connection works, connects to the previously trusted network. However, I cannot scan or see the available network in the settings, i.e. select another hotspot, nor turn on/off. In order to remedy the issue, I had to turn the Airplane mode on/off or reboot . Any thoughts. Thanks in advance. BTW - under the WiFi>Advanced settings, I selected keep WiFi on during sleep when plugged-in.

Bluetooth major issue with Wifi

I completely agree. I wonder if some of you are experiencing the bluetooth/wifi conflict. For instance, I like to use a bluetooth speaker to listen to music or maybe watch youtube videos since it's much better than the stock tab speakers. I can watch youtube perfectly fine w/o the speaker synced but once I sync it my video starts to buffer constantly. Sometimes a small notification pops up saying that it connected to my home wifi (even if it already was).

Although far from scientific, I did a few runs of speedtest under different scenarios. There was a clear dip in DL speeds when I was playing music through my BT speaker. Music through just the tablet's speaker did not hinder the connection at all. (screenshot attached).

RUNS:

1 - BT OFF

2 - BT ON

3 - BT ON AND PLAYING

4 - BT OFF AND PLAYING

5 - BT ON AGAIN AND PLAYING

I contacted Samsung Support on FB, but was asked to call their Remote Support group, 1-800-726-7864. I have yet have the time to call. It's a small issue, probably not worth the time, but I will when not so busy. I am hoping for a quick fix. Will continue to monitor and test. It could be a toggle setting. BTW - I am running full stock, not rooted.

I don't have any issue with WiFi signal, it's in the Samsung Book Cover case. In fact, it performs better then my laptop connection.

Update 8/19/14: The WiFi issue previously mentioned was sorted. Not sure if it had anything to do with the two apps installed, Greenify & GSam Battery Monitor.
[Galaxy Tab Pro 12.2, 10.1, 8.4 Q&A, Help & Trouble] Raistlin1:
I just got the Tab Pro 8.4 and notice the same issues with wifi, when in portrait mode if you hold it on the bottom left wifi signal drops and if you turn it into landscape mode (not upside down) when you hold it with your hand on the bottom right the signal drops even worse.

I only stumbled across this because the first few times using the Tab I noticed that it would reconnect to my network and thought that was strange, googled it and came across this thread. So of course I test holding it in all the places that you guys say causes a drop and mine drops. Did most of the testing before updating to the latest OTA update, so after that I decided to take the update to see if that would help. I also did a factory reset after the update but it was late last night so I will test it tonight.

I am still within my return window for BestBuy so I may just keep returning until I find one that does not do this. I also have the Samsung book cover on order so I am hoping that maybe the book cover will help.

Has anyone tested or noticed that if you put a case/bumper/cover on and then hold it if the signal drops? I am thinking a la antenna gate for the iphone where the bumper was the "cure".

I have an OG Galaxy Tab 10.1 and that thing has better wifi than this, if I can get a Tab Pro without this issue I may go with the Tab S or just wait for the next Nexus tablet.

To be honest, please don't assume that EVERY Tab Pro 8.4 has this issue.

Here's my experience, as an example. I've had my TabPro 8.4 for 2 months - 1st month, no case. 2nd month, Samsung OEM case.

For my 1st month I almost always held the tab in portrait orientation, in the lower left hand corner. Only ONCE did the wifi actually cut out entirely, usually what happened is: the wifi signal would go down 1 bar. The wi-fi was still perfectly functional, it was just connecting at 50mbps to my router, instead of 65mbps (TP-Link wireless-N router). Since my internet speed is only 35mbps, not much impact to me...

For my 2nd month, i got the book cover case, so sometimes i use landscape orientation (using case as a "stand") - no prob whatsoever.

And now in portrait orientation with the case on, sometimes the problem doesn't occur at all, because i will hold it in lower left corner and wifi signal does not change! i think it's because the corner of the book cover is "protecting" it. But sometimes it still happens anyways (i.e. wifi goes down 1 bar), but it's not as often as before.

end result: even as someone who occasionally holds it in lower-left corner, it's a non-issue for me. i would never have returned it for this issue.

OK just saw the last messages that xda dev app didn't show me. I hate this paid app.

Rotating when having the cover is not always practical.

I get the same problem when charging my 10.1...

Exchanged the Tab Pro 8.4 tonight and just started testing it out but so far it seems better than my previous one. Signal still drops but it is not as constant as my previous one and seems to be a better signal when holding in that spot. I have the Samsung book cover case coming so hoping that helps a bit.

Something else I just noticed, when I place this Tab on my stomach in portrait mode my WiFi signal drops, comes back as soon as I move it, very strange. This has happened twice so far and when I tried it again the signal dropped down a lot but didn't disconnect this time. I am not laying tab down on my stomach I am still holdin it just lowering it so bottom is resting on my stomach.

[Galaxy Tab Pro 12.2, 10.1, 8.4 Q&A, Help & Trouble] crane at citrus:
I don't have any wifi problems "now"! Thought I did when I got the Pro 8.4 this week as using Netgear's genie app, I saw only around 29 Mbps between the Netgear 6200v2 & the 8.4. Then in the Pro's setting for wifi, I saw both my 2.4 g & 5g bands listed even tho I had setup the 8.4 to connect to the 5g band! Next day checking on the connect speed & the wifi connection, I saw that the 8.4 was connected via the lower 2.4 g band; decided to tell the 8.4 to "forget" the lower band so that the tablet will connect to the router via the 5g.

Somewhat later I found that the connection speed was around 120 Mbps AFTER I had woken the tablet but the also saw the connect speed started to rise! Much later after some ebook reading, the connect speed went up to around 320+ Mbps; much happier since the it was using the AC 5 g connection. After some up/down loads & usage a couple of days later, I saw 433 Mbps possible; the Pro 8.4 is now charging & I just went to check the speed (the tablet is now in a case), did a "swipe" to wake, ran genie & saw that the connect speed was 234 Mbps.

I have a feeling that the Tab Pro 8.4 also lower the wifi connection when going to "sleep"/screen-saver mode. The connection icon have alwasy shown full blast & the router is in a different room than when I use the tablet. Only have the Pro 8.4 for about 1 week, but all is well with the connection speed; will see if I can find the signal strength app & check that....
[Galaxy Tab Pro 12.2, 10.1, 8.4 Q&A, Help & Trouble] crane at citrus:
I installed "wifi overview 360" on all my tablets to check the wifi signal for any problems even if I get good results.

Now, my stock, TN320UEU1ANG1 kernel version, reads between -48 to -53 db; the Nexus 7, 2013 reads the same; both connected to the 5 ghz. The router is a Netgear r6200v2.

Checking the other tablets connecting via the 2.4 ghz, the Nook HD+ get between -43 to -53 db; the Acer A700 & the Asus memopad also has about the same -43 to -53 db.

The distances to the router is arount 15 to 20 feet; there is a wall in-between (different room); the router is located under a very old computer desk. No problems with the internet, computer or printer.

Guess I got lucky or the problem lies elsewhere. I did see -100 db (no connection) with Netgear's app for the Nexus 7; however, Netgear's wifi analytic app evidently is a bad app as it was the only wifi app I tried that can't find the wifi connection even if the Nexus 7 was connected!

I had thought that the problem was due to Android 4.4.2 at first as the Nexus 7 is at 4.4.4; the other tablets have been "rommed" to 4.4.4 & have verified that wasn't the problem. Also, all the tablets have a case...... However, my Pro 8.4 is only 6 days old as of this writing.......
