Have any of you guys had any problems with Wi-Fi on the Galaxy Tab?
I've been trying to connect this device with a wide range of routers and keep ending up with no or a very poor signal.
Just upgraded to firmware P1000XWJJ3 and the problem persists.

no, i don't have such problem on JID firmware
BTW how did you update it to JJ3?

How far away from the router? Any walls between?
My Tab works pretty well if i'm close to the router, but with some distance between - oh say 5-6 meters - it rapidly decreases and soon enough drop the connection all together. Very strange, been trying different routers and different settings and it's the same all over the board.
Regarding the firmware (JJ3), just go to http://www.samfirmware.com/ click "Tablets" and select firmware and then install with Odin. Easy as one, two, three.
MIne works fine with through thick walls on the balcony. What wireless security/ preamble type have you got? Is the router set to 20/40? Is it transmitting at 100% or auto?
The router doesn't matter. If i sit on my balcony smoking a cigarette, I either have a weak signal or the tab switches to 3G. My phone or laptop hold the signal easily.
The distance is like 5 meters and 3 wals between us. One of them concrete. But my phone holds the signal there, while my tab doesn't. On the other hand my wife's SE Xperia X10 barely holds inside the living room. So I guess android in general is not that good with wireless.

Of course the router matters mate. Instead of guessing why dont you try to troubleshoot... surely logic alone will tell you that its not your tab as a)noone else is having this problem b)your xperia is.
If it ain't broken - don't fix it. This router serves half a dosen of devices. Only android ones are having issues.
My laptop, my wife and my daughter's laptops, my htpc and my son's desktops as well as my phone are OK with it. It is on 100% and no encryption. I have it for years now and it never disappointed me. Why should I blame the router?
For one thing, if youve had it for years it is possible there are firmware updates that will immediately improve the connection of both your working devices and the newer, less backwards compatible android devices.
There are also security frames and CTS overhead to consider. Your router may just be too old to communicate with the newer radios in the android devices. These things happen all the time. Just google wifi problem and add any device you can think of to the end of that... there will be people conplaining about weak signal everywhere, and its usually the routers that are at fault.
EDIT: If it aint broke dont fix it is not an acceptable philosophy for a gadget lover

Well we have several people tried flashing this firmware and it is failing.
Can you be more specific on how you flashed it?
Which PIT file did you use?
Did you select repartition in ODIN?
How is the browser in JJ3? is it smoother than shipped stock?
Thanks.

I've tried a multitude of different settings and it can't even compare to my Nexus One or Galaxy S. Keeps dropping the connection and report a signal strength of about 10%, it's driving me nuts! My current configuration is as follows:
Router: Netgear WNR3500v2
Firmware: DD-WRT v24-sp2 (08/07/10) min
Network:NG-Mixed
Channel:2 (2.417 GHz)
Channel width: 20 MHz
TX Power:71 mW (Default setting)
Security: TKIP+AES

Simply flashed with default ODIN settings and both EUR firmware and EUR PIT-file ( Galaxy Tab / .PIT File: DOWNLOAD. (EUR). I didn't do a wipe before nor did I clear dalvik cache or any such thing.
Can't really tell about the browser, from my point of view it feels pretty much the same.

explanation
The problem is almost certainly your old wifi router having bugs with PSP (power save mode). Android relies on the PSP standard to reduce the power usage on Wifi, your laptop and other old devices probably don't. I've seen old routers disconnecting almost immediately with android devices...
You can try setting "Wifi Sleep Policy" set to "Never" (will impact battery live, obviously). Though there was a bug fixed in ~July where Android would still use PSP, and the tab might not have the fix yet.
But the best fix is to buy a new router. It is broken, standards-wise, and needs to be fixed. Also, newer wifi routers are a lot faster and generally hold the connection better, so its really a no-brainer...
Ditto my brother!

I have to agree... I have two instances of WiFi use with my new Tab:
1) At home, older Netgear router (not that old mind you) - DG834PN - Does 802.11b/g/Super G
2) At work, brand new Netgear router (brand spankin' new) - Wireless N etc
At work, my connection on the tab is consistent without a drop out, fault less and constantly fast. Even the signal strength is good across the other side of the building.
At home however on my older router (no Wireless N) it's slow, signal strength is poor and constant drop outs are present. I need to hit "Retry" on the network connection box so often at home.
So yeah I feel that should be fairly conclusive. The Tab seems to like brand new wireless hardware.
No wonder. 802.11N is much stronger WRT to power since it has 2 antennas. But it is still the tab to blame that it doesn't hold a signal of standard equipment.
Actually, the problem you're having at home is super g. Its not a wireless standard. If it is working in 20/40 auto mode, just switch it to 20 only. This should improve your network connection in general.
Also gonsider using g only - b is pretty redundant by now.

My router lists b and g, g only or Auto 108mbps.
I have had it selected on g only for a while now.
What settings does it have for the super g... does it give you the option of disbling pairing or something like that? It could be the bonding that causes your disconnects.
Yay so I'm really happy about the iconia so far. The whole no acees to SD card through computer while connected to the computer will take some getting used to, but its the wifi that'll probably get this sent back. It's really bad. I've reset the connection half a dozen times since last night because it keeps hangin and can only downloads app when in the same room with the router.
Now the issue is that I'm laying beside the router now and getting 2 bars. If I sit up I get 3 bars. Yippee. The signal in the bedroom, on the first floor, get maybe 1 bar and I can't stream or download anything in there. I never get a great wifi signal in there', but its between 2 and 3 bars on my phone and netbook,. I wondered if there might be some interference so brought up the handy wifi analyzer and found 4 other wifi signals all on the first channel, so now my router is on channel 11. It didn't help any :-\
So if I exchange it, will the new unit possibly be an improvement? Is this just the way it is?
I noticed that the connection quality drops sharply the further away you are, but atleast on my tablet it still doesn't drop as sharply as in your case. I have the router here in living room and I get 65Mbps, everything works fine. Then if I move to bedroom or kitchen it drops to something around 20Mbps, yet it still works just fine.
What type of router do you use.I have a newer netgear with no issues my router is in the basement at front of house almost under the front porch.concrete ceiling above it. I can go out to my back yard approximately 200 feet and still get 1 bar and OK speed.I do notice. That the indicator bars do not exactly deplict your signal strength.
I also know there is a issue with some routers and the network card in this device I read in a thread long back.you have to turn off n or g feature I think it was.but do firmware update on router as well might help.not all routers are created equally Linksys sucks in my book. Lately
I can also see neighbors wifi signal but 1 bar they are 500 feet. Prob could not connect thou
Wish you lots of luck
hmmmmm
You could have a faulty Wi-Fi antenna ...
More likely, you are using a cheap router or a router with out of date firmware. Have you checked to make sure you have kept your router up to date with the latest firmware?
Also, have you tested this with other routers? If a multitude of routers show the same issue - you likely have a hardware problem with the a500 - if only your router shows this problem, then likely it is a problem with your local router.
a different unit MAY help, but I would try friends routers n such. My router blows but I can still stream Netflix no problem all the way across the house. I can't even do that on my laptop which has a beastly card. +1 for updating your router and device though, that might help.
Thanks for the replies. I have an old Motorola sbg900. I think I bought it 2 years ago. I have noticed that the iconia doesn't see as many networks as my phone does and the speedtest results are interesting. I left everything default in the app. By the router, I get 9 mb/s with the iconia vs 7 mb/s with the phone. In the bedroom, I get. .8 mb/s on the iconia and almost 6 mb/s on the phone. That is a huge drop and gap :'( I'll look up updating the router. I've never had connection problems before and we have 2 desktops upstairs plus both me and my roommates phones and both laptops and the wii and xbox. I just hope I can get some signal improvements on this nifty device.
sounds like firmware or...
I would find a friend with a different type of wifi router and test your connection with it. That way you get a pretty good indication of if you have a issue with your router or an issue with your Iconia.
Bother, my work wifi allows me to connect, but doesn't allow me to do anything with the connection. I am connected, but cannot do a speedtest. Relying only on bars the phone gets all 4 while the iconia gets only 3. The iconia also only sees 3 of the wifi signals in the building while my phone picks up 7 plus an open adhoc network. I know, it's time to visit with some friends so I can do a second test or maybe this is an excuse to go out for lunch today
ETA: At McDonalds, both devices had 3 bars and identical download and upload speeds. I've gone ahead and ordered a cheap $20 wireless n router to see if that improves things. It should arrive tomorrow, but since it's coming via UPS, it may not arrive until Monday.
so i've been getting wifi drops for a while now...never really tested until last night. Seems, around 15 yards from my router, though a wall or two granted....I only get 1-2 bars of signal. In this 1-2 range, (my couch), it will drop the wifi signal approximately every 15-20 seconds....stay unconnected for 1 second and then reconnect. If I get closer to the router though, no drops. I don't understand why the tab can't hold a low signal for wireless consistently.

I was having this same issue. What fixed everything up for me was setting my router to use Long Preamble. A500 & HP Netbook stay connected now.
Give that a shot. Good luck!
I believe there aare issues with some routers.or maybe settions some have on there routers.I have a 40.00 netgear b/g/n .router its located in my basement back at the end of the hall kinda under the kitchen.I can go out back about 20 yards from the house and still have 1-2 bars
Also my Iconia will see several neighbors routers and the house are all in the center of double size lots.the one signal I pick up with two bars I know is in the house across the street.
My router security is simple I have dhcp on.but secure by Mac address.this could be a solution.set this then add each device in the Mac assess pannel in the router.bye the way this is the most secure.I.also.have broadcasting turned off.to get another computer to even see my router I have to log into the router from another computer.then give the new machine access.I use this due to open file sharing.
Good luck.

More to the point, you could be behind 1 wall and get a bad signal which might not have anything to do with the tablet. If you've got insulated walls that use a foil wrap, good night.
Plus 45feet, while not particularly far away, when you couple walls and electromagnetic interference + distant, those all add to the level of signal degradation. If you've *properly* taken into account all the variables, then [and only then] can you quantify the wifi capabilities of the tablet.
I'm not saying you didn't, I'm just throwing this into the discussion with my primary point being that short distance and few walls [generalizing] isn't equal to a devices capability to process a signal. (;
nice replies...thanks....I'll try the long preamble...not sure what that is will have to research. And yea gamma, that is definitely true about the different kinds of walls etc. I can use my thunderbolt's wifi perfectly from anywhere in the house and actually out of the house at my daughters swingset which is a good 75 yards away. Apples and oranges I know....but i've never had wifi signal problems in this house otherwise except for the iconia. I am fairly sure it's a conflict with the router and the tab of some sort
It all depends on the device radio and router combination. I have an ASUS WAP that doesn't play well with Atheros brand radios. Switched my laptop to an Intel WiFi radio and away went my connection issues. Both my Motorola Atrix and my Acer Iconia have the same range/connection speed, no problems with dropped connection that I've found. Take it to my parents house with a Linksys WAP and problems galore.
Can anyone confirm or not if the crap WiFi strength on nexus 10s is an acknowledged fact? I have seen some say it is, yet still see other comments praising the devices WiFi saying it is stronger than ipones etc.
This is my second N10, I sent the first back due to WiFi performance and I believed it to be defective. My second devices arrival has suggested otherwise as I have noticed no improvement.... Am I just really unlucky?
On my home network, every other device has ho WiFi issues, but my n10 struggles! It seems to sho a decent signal strength in the WiFilist in settings, but a low strength in the top right corner.... Can anyone advise? I get similar strength issues on other networks (public and at friends houses. SO frustrating not being able to perform one of the most basic functions on a £300+ device). Was hoping 4.3/4 upgrades would help- nothing.
Should I get a third nexus sent out? Is this down to poor quality components? Anyone having same issues?
Thanks!
Hard to generalize, but mine has been rock-solid (on 4.3; I'm holding off on "upgrading" to 4.4). Seems to give faster throughput than my N7
My N10 seems to be at par or a bit better than my better halfs Ipad. Taking both tablets and going for a walk out in back (acreage), in the outbuildings, and near fences, the signal strength and ability to connect to my router and see other routers was actually a touch better with the N10.
When first getting the N10, it did seem to drop the wifi signal, but replacing the el cheapo several year old router with a newer medium price router cured that issue.
The Google Nexus 10 as well as the Amazon Kindle HDX are two of the few devices that actually support MIMO (multiple input multiple output) wireless.
This typically allows for very solid and swift wireless performance.
I suspect that software updates may have had some impact on the Wireless functionality of the Nexus 10, but that is also in combination with some types of access points, so it varies to each customer.
Some places I get really terrible wireless, but at both my work and at home, it performs extremely well.
Hopefully a future KitKat patch will address the wireless more. I notice that new binaries are included in KitKat pertaining to both wireless and Bluetooth for the N10.
Hello, I just became an owner of a Nexus 10. when I first time connect to my BSNL Teracom wifi router it is not connected. it is always showing connecting or obtaining IP address...
It connected through my S3 Hotspot but not through teracom router
I wake up in the morning and just press again the connect button. Bingo...it is connected..!!! Not understand why it is behaving like this. I am not done any changes in routers settings also. Is it not connecting b'coz the routers frequency mismatch or anything else ?? After once I switch off and on the router the same problem happens
all my phones including a Samsung s3, tab neo and also my laptop all are switches automatically connected to the wifi router.
Please help.
thanks in advance.

Yup... Crap WiFi on my nexus 10 too. Just randomly disconnects or is so slow that its unusable for streaming movies... I own a ton of android devices and this is the only one that gives me problems. When I turn it on, I just hope it stays connected. Let's hope this post goes through lol

Mine pulls 40mb out of a n wifi connection.. the main connection is only 50 -55 on average. I'd say its the best performing wifi device I own.
I have owned my N10 for over a year. The WIFI signal strength is good, but I often get some lag issues, which ended up being my router. When I have issues, I now reset my modem and everything works again. I have read that some people only have a 2.4GHz modem, and they have received better luck by limiting WIFI to that frequency only.
How best to hold your tablet so you don't block the antenna.
http://youtu.be/7v3AR6gZNYQ
This might be an isolated problem? I walked to the farthest part of my house that still gave me full bars and held my hand over where the video showed and I was fine. No issues what so ever.
Since OTA1.1 AND doing complete factory wipe and boot I can no longer complain as it's rock solid no matter how it's held, at least on 2g.

I got to agree, my shield's WiFi is pretty strong next to and upstairs away from my router, never had any problems from the start.
I guess some tablets are affected more than others.
This is mostly a 5ghz wifi issue when you are at the edge of the range (2 bars). I'm going to be making a long term review video soon that will address this. Also having a cover can help as well.

I've taken the advice from some users on the NVidia Forums and have provisioned separate access points for 2.4Ghz and 5Ghz so I can connect directly to each one when required.
It's a workaround until I get my RMA after the Cracked Case updated tablets are received and dispatched.

If your router allows it you should ALWAYS have your 2.4 GHz and your 5.0 ghz set up as two different networks. It will make the speed on your 5 GHz WAY faster. Also it allows you to pick specific devices to connect to each network type.
Name them both something different and give them both different passwords.

I just got my tablet yesterday. I was setting it up last night, and noticed ALOT of wifi lag. I don't really hold it in landscape, I hold it in portrait mode, and I hold it almost exactly where that video shows the wifi antenna to be. In the bottom right corner, I would think, is where most people would hold a tablet, so I am surprised they put the antenna there. You would think they would put at the top.
I will test this more tonight. I might exchange it if I see those same issues.

In landscape mode the antenna is at the top. It's where the stylus is. In portrait mode you can hold it either way.
My biggest concern is for a tablet that needs great 5ghz wifi performance, they only used one wifi antenna.

According to that video, the wifi antenna is in the lower right corner in portrait mode, right where I hold it.
I never have much luck with 5ghz wifi in my house, so I stick to the 2.4ghz band. I have a netgear R6250, and the 5ghz AP works great if I am on the same floor as the router. On the other two floors, it drops in and out on most of my devices (iphones, android phones, ipads, even my alienware x51)
I posted this in the Nvidia forum as well.
I've tested the wifi on my tablet in a bunch of different ways using ookla speed test and general chrome browsing. I have come to pretty much the same conclusion most people in here have. The wifi is weaker than most other wifi devices but this will not be noticed in an ideal wifi setup. For folks with less than ideal wifi setups, they are affected more.
There are a few caveats to my test: I am not using gamestream, so I can not comment on that. And I have such low wifi speed from my ISP (30mbps), that I can not test 5ghz top download speeds vs 2.4ghz top download speeds (because they both easily top out at 30mbps).
I want to go over the things that have improved my wifi performance.
1: Switching to 2.4ghz wifi. This has made the biggest difference for me. Paul Deemer was saying that not using 5ghz wifi is the best for the ST and I agree. I will switch to 5ghz when I gamestream and switch it back to 2.4ghz when I'm done gamestreaming (when I finally get my gaming PC back next month).
If you do need to use 5ghz wifi, see below for other improvements.
2: Using a wifi analyzer app to set my wifi channels up. My apple router is supposed to do this automatically, but when I used the wifi analyzer app I noticed that my channels were crowded.
I set my 2.4ghz wifi channel to an empty channel and I got a full bar more wifi strength in my living room. I set my 5ghz wifi to the highest channel I possibly could (I think 160) and I got a full bar more wifi strength in my living room as well.
3: Avoiding the wifi antenna. This only affects 5ghz wifi for me. When I use 2.4ghz this issue goes away.
http://youtu.be/7v3AR6gZNYQ
4: Using a cover. The cover seems to keep you hand from interfering with the wifi antenna. This is not a total fix, but it does help. Just like in this video at 6:30.
Wifi Death Grip Samsung Galaxy S4 Workaround: http://youtu.be/ySIUuMAvduM
5: Moving your router. If you're having wifi issues you could always try moving your router. I will be moving my router to my living room where I eventually will be gamestreaming.
All of this stuff has been talked about before in this thread and others. I just hope to help anyone out who is still having wifi issues.
I too noticed the issue was somewhat mitigated using a cover. But I still noticed many periods of lag (waiting for data to load) in apps. Even a few occasions of "Network connectivity issues". Reloading would make it go away.
I just sent my shield tablet back. In addition to the wifi, I have noticed twice now, the battery has gone from 70-80% to dead in just a few hours. With the screen off.
Strange ! Me that's reverse ! I have a 16 gb model. On a 2,4Ghz router.
