I solved the wifi issues by putting a sim card in my tab 7.7. I ve being using it for two days now and it is working perfectly
[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] c4Lvin:
Yes I first didn't put a SIM card when I was having problems. I then put one in and problem resolved for an entire day. But last night had the same problem. At least turning on/off fixes it now without having to do anything else. I also did a few tests myself...will write up about it in 1 hour time.
[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] dhofar:
I've a similar problem , it went away for some time and then back again > official or not this rom released with bugs all around for sure , some of them are forgivable while others are not (wifi) ..the best table let down by samsung's dev. they should ask for help from other companies like Asus .. shame on you samsung . wifi problems all over the world .. for those who having working wifi it's matter of time before you fall into the hole of wifi malufunction. they tried to save power consumption but at account of malufuctioning wifi .. that's not an enhancement of wifi drivers it's actually destroying their reputation .. not being only late and behind other companies for ICS launching but producing one of the worst ever ... what's destinguish them from others primarly it is Samolid tech. Asus should continue where others left incomplete projects.. deferent form factors are so important for consumers .. take the risk Asus am sure you could win the race ... ( still loving mrs 7.7 )
[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] ikeny:
Thanks. However, I've always had my SIM inside, although not data plan. Do you think that makes a difference?

By the way, my 7.7 now connects to 5 GHz band. I flashed back to HC, got the 5 GHz N band connected, then flashed ICS with mobile Odin. After that, it recognized and connected to 5 GHz wifi.

Still only able have it work for a short time, before it disconnects itself. Then I have to each toggle wifi on/off, or restart to get it back.
[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] ixomon:
Actually doesn't make any difference if sim card with our without data plan is inserted in Tab.

With several different tries I only came to the conclusion that it helps to clear the dalvic cache for at least the first connect. This will be only temporarily and after a while the connection is dropped again. Latest if you put device into deep sleep or change wifi hot spot.
[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] wai98:
Hi, All,

I got the same issue and I tried to configure my wifi router WiFi setting from country HK to World (Openwrt).

My Tab 7.7 (HK) would be connected to the Wifi again without any issue.

Now, i will keep checking if the same issue would happen again these few days

Hope this information would be helpful to all.
[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] ikeny:
I agree with dhofar, the wifi problem has to do with the wifi sleep policy. Currently, there are 3 choices, but I don't think this build of ICS makes any differentiation on what you pick. It always tries to put the wifi to sleep after a long standby. The problem then begins when waking up or reconnecting wifi after sleep.

Also, it highly depends on your router. In my case, it works 100% at University (don't know what router), but constantly has problem at home (Apple Airport Extreme Base Station). This explains why some people are experience issues, while others claim it works perfectly fine.
[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] salfer:
I have the same problem.

Whit my Apple Airport Extreme Base Station i always lost the connection after a few time and wont be able to reconnect, only if i tur off and on my device. But in my company we have a 801.11G router and it works fine.

I tink is hast to do whit the router settings also. But whit honeycomb I had no issue.
[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] ikeny:
I spent all morning trying different configurations on my Airport Extreme; no security, a/n, b/g. I even got out my Airport Express and tried setting it up as router. No luck at all. I'll dig out my old linksys g router next to test it.
[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] ikeny:
Here's the results with a Linksys 802.11b router.

1. Powered off the AEBS, turned on the Linksys, connects beautifully. Zero problem.

2. Both AEBS and Linksys are on, tablet could not connect to anything. That's right, the AEBS is messing it up even when the tablet is not connected to it.

3. Just having the AEBS on, wifi analysis app could not detect any signals, even when it's not connected to any network.

4. Turned off all routers in house. Wifi analysis app immediately detects my neighbours routers.

Conclusion, the combination my AEBS with ICS is lethal, even when tablet is not connected to it.
[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] ikeny:
So I started googling "AEBS and android wifi problem" and came cross this post

http://androidforums.com/droid-how-tips/258840-solved-droid-wifi-problem-apple-airport-express.html

It recommeded an app called wifi fixer. It works!

Doesn't correcr the stem of the issue, but it reconnects wifi for you automatically and quickly. It's the best and only solution I can find, other than reverting back to honeycomb.

please help

Can someone upload the HC firmware for HK version? I would like to flash mine back to stock. Tried flashing the stock ROM from ATO but for some reason I couldn't get passed the boot screen with the Samsung logo. What am I doing wrong? I'm flashing with Odin 1.85 for windows. This wifi issue is driving me crazy. One minute I get connection and the next minute it would drop and I tried restart and turned off the power but nothing worked.
[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] tanit9999:
I think the cause of wifi issue is wifi channel . try to using "App Wifi Analyzer " in play store for config your device and change you receive wifi channel

sorry about my English.

I am Bummed that quite a few people have been having issues with ICS and I hope I do not have to deal with such issues. Living in Australia the P6800 is not available so I had to purchase mine online.

The original ROM it came with was a P6800JPKL4.

I tried several different stock roms as I was looking fora rom that was stable and a radio or baseband that was compatible with the telco I use here Telstra. I ended up settling on the P6800XXLB4 rom Made for France.

As I use my Tab as a phone as well as my means of internet connectivity when I am away from my home wifi a stable and consistent signal is priority.

Having updated to ICS for 6 days now all is ok I have good consistent signal and so far no issues with wifi. ICS itself runs sweetly.

I hope my luck continues as I hope you all find solutions to your wifi issues.

One thing I have been wondering is that it may be possible that not all the tabs were built equally as was the case a few other Phones, Tabs.

Luck to all

I have my wifi set to always on under keep wifi on during sleep under advanced settings. No drops so far. Router shows a 1 mbps connection during device sleep.
[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] dhofar:
it's to be somthing else ?

changed base band to home HC rom and/or limiting routor to G only mode all to no avail.same symptoms * even trying to connect to any mobile's hot spot is a similar wifi's problems!

symptoms YOU samsungs are :

the wifi switch sometime may flicker or toggle on/off by its own!having the tab in flight mode then off again would cured it ..in the other side (the right hand of the wifi -status)

instead of connected for the normal operation you may have saved or not in range or simply empty page ..

the most logical solutions are mentioned above but even then still the same issue repeats itself from time to time! still looking for upgrading to ICS damn if you do and damn if you don't (but I love you 7.7 * an old song) .. there're some of us keep telling wifi is ok I do beleive that but really am not quite convinced with the steps taken to sort out wifi's issues ... with HC mixed mode routor operation is not an issue at all (wifi simply is top notch).. HC modem why it won't work as it should for the ICS? is it because of a defferent OS and such compatibility is not running that well specifically with 7.7 device ?

Samsung you're killing US badly .. Is it a rat race or what ? I guess 70% or higher of those who upgraded to ICS suffering similar issues while your techs. keep watching and do nothing i just hope they're not laughing too much !

[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] dj_rene:
guus, i also have my p6800 upgraded by this friday. the previous one is the official hk rom laxx.

i just use odin to flash without wipd and factory reset.

all comes perfect but just wifi. the wifi is good when first time boot into the ics, but after couple of hours wifi just gone all of a sudden

but now i found a temp workarond which might help.

1. remove all remembered wifi profile.

2. enable the airplan mode.

3. reboot. (not shutdown)

4. enable wifi only.

5. connect to your wifi

6. disable the air plan mode.

i tested 2 times, works so far.

hope above will help.

I only have driving mode. Lost airplane mode
[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] dhofar:
thnx for the feedback but that's again tried among dozens of solutions all to no avail . the best i could think of is\was the modem file where anyone would think this the most logical one ! but due to defferent OS this is not enough , well at least for alot of us around the world though for some it worked through this door .

this will work for sometimes ..actually you could try to put the tab on filght mode whenever you have wifi drop and let it there for sometime (I don't know if the system is releasing any un-neaded file\s through this period ) while that put off wifi and then again on , the chance you'd have wifi again is great.. rebooting is a long process anyway.. I think (i'm not sure) keeping the flght mode on would survive wifi's connection even more but eventially you'll be disconnected from time to time ..wifi and flight mode surely are doing pretty nasty things also auto switching to wifi connection is not right in some stages .. so keeping flght mode on would realy help lasting wifi connection ( this i've tried it many times)

as for yet the only and the last true solution for wifi drops is going back to HC !

I remember my friend who's having an Asus transformer with wifi issues (not severe like ours here) when first ics launched but quickly asus fixed wifi issues .. samsun? try to learn support sometime could be so vital for future purchase and try to employ good quallified people .

note: after 5 hours of stable wifi connection

for the first time since upgraded to ics i've stable connection beyond 5 hours ! great ...just have flight mode on while connected to wifi , at first you'd have some drops but after a while the wifi connection would be stable , it seems one could have flight mode off but disabling the network data ! this what i beleive is interpreting the wifi connection , well it's true from my point of view anyhow .till now i didn't try to putt off flight mode and enable gsm without data (3g\edge).. it's more likely this wouldn't interfere with wifi connection hopefully .. not quite happy with this result but it's as the name suggests for this link ( partially) .. try it i'm sure it'd be helpfull for some of us here ...
[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] dhofar:
I was woundering in my previouse post here " it's to be something else!

i'm not claiming for sure i've found what's making wifi drops but in my case YES .. it's packet data interfering with wifi connection..it's when wifi is trying to take over the connection from data packet of 3g/edge that's where keeping the priority for wifi suffering such drops ..I can confirm for more than 7 hours sleep or not the tab still keep wifi connected all times ..2 hours with flight mode off but with packet data off .. now all i've to do is to remember whenever i come home to turn off packet data in order to have stable wifi connection.. well this looks reasonable enough for me. samsun(g) we don't like half solutions !

Try it --it made my day more brighter --i would advice you first to disable data packet before installing the app although it might be unneccessary for such approach ,i mentioned this just to avoid any interfering with data packet-- once you've got app excuted as instructed enable data packet .

Running wifi smooth as it was under hc --now i can enjoy ics free of affective troubles ,some bugs are existed though - i'd blame samsung once again for not providing any support towards this issue -this app /fix shoud have been done by them -anyhow billion thnx for the person behind it

I have very unstable wifi connection after upgarde to ICS 4.04. Keep dropping or simply can't connect.

I tried two softwares, FXR Wifi Fix and Wifix Manager, without any luck. Factory reset didn't help neither.

Flash baseband to XXLA3. Problem still persists.

Finally, I solved my problem today. I installed Wifi Manager from Play Store. It works like magic. Test a couple of connections at office, home, and a 3G router, it just simply connect and never drops.

Try it out. Hope that it helps all of you who have wifi problem after upgrading to ICS 4.04.

[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] CK563:
Another tips. I usually turn my phone to airline mode at night so to decrease the radio activities/level from the night stand. It usually takes a while/reboot for it to reconnect in the morning, even after I used almost all of the apps mentioned here.

So I stop putting the tab next top me at night and keep it on all the time.use an iPhone as my alarm these days. And it never stop/drops wifi since.

Next test is my next travel.

[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] Graz:
Tried:

- full wipe & back to HC (wifi is stable)

- full wipe & reinstall ICS

- Installed CWM and tried the wifi fix thing

Nothing I've tried works...my wifi is so unstable with ICS that I can't even stay connected long enough to get apk installer from the market (and it's a TINY app).

The Samsung developer who released ICS build this needs to be slapped in the head...this is just ridiculous.

I'm now faced with the choice of going back to HC and re-setting everything up from scratch, or waiting for a stable release.
[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] Josvaz:
How about reboot yr wifi?
[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] Graz:
Do you mean cycle wifi on/off? No, that doesn't solve the problem. This problem seems very likely to be code or ics wifi driver related. Symptoms include:

- Brief wifi connectivity (and when I say 'brief', I mean maybe a minute or two...or even less at times)

- Frequent drops of wifi

- Cycling wifi on/off does nothing

- Go into wifi settings and access points that are clearly within range (a few feet!) show as out of range

- Or go into wifi settings and NO access points show within range

- Restarting or power cycling the tablet sometimes gives brief connectivity upon start-up, but it's extremely short lived

No combination of other settings (bluetooth, GPS, etc. off or on), persistent wifi in sleep, or anything else I've tried seems to resolve this. For me, this release of ICS is simply unusable in it's current state. This definitely isn't hardware...HC works flawlessly. Although, I'm very curious to understand why some folks are reporting no wifi issues with ICS...this seems very strange.
[Galaxy Tab 7.7 Q&A, Help & Troubleshooting] Graz:
Update...

- Installed HC...rainbows & unicorns...wifi is happy

- Installed Wifi Manager under HC (couldn't stay connected in ICS long enough to ever pull it down from the Play Store).

- Still under HC, I set a static IP address for my preferred access point

- And then, back to ICS again (latest HK version)...

- Initially wasn't looking good...same unstable wifi as before.

- Launched Wifi Manager...again initially didn't seem like it was going to help...and then suddenly...connection. Solid. Strong. No drops.

I don't know what this Wifi Manager app does...there don't seem to be any significant settings to manipulate. But I've been connected without interruption for about 2 hours now...something I was never able to achieve before with ICS.

No idea at this point if it'll remain solid through a reboot...I'll try it later. But for now I can say that this seems to be working for me...too early to declare victory at this point, but I'm encouraged.

Good luck.

Update #2:

- Wifi signal lock almost all day (5-6 hours uninterrupted)...all my apps & games loaded from Play Store with no loss of signal at any point

- Left the tablet sitting for a while & came back to find no Wifi signal...played around with Wifi Manager & rebooted a few times, but couldn't get wifi back

- CWM installed & Rooted; installed & loaded WiFixManager.apk from here: http://xdaforums.com/showthread.php?p=21406675

- ...instant wifi lock, persistent after reboots. 1-2 hours now without wifi drop...we'll see how it goes.

Update #3:

- Overnight dropped connection (surprised?)

- Reboot, play with Wifi Manager...finally reconnects for a while, then drops for no apparent reason

- Struggle to re-establish connection...

- There just doesn't seem to be any discernible pattern here...connections happen out of the blue, and drops are just as unpredictable. Nothing to put your finger on & say "if I do this, it connects" or "when I do this, it drops"

In conclusion... Wifi Manager & the Wifi fix seem to help somewhat, but they're in no way a total fix (at least not for me). I'm willing to try any suggestions & will update my findings to the post.
