Wifi Sleep after ICS Update?????

I recently updated my Galaxy Tab 10.1 Wifi to ICS via Kies.
Evertying works, except If I got into the advanced wifi settings and set "keep wifi on during sleep" to NEVER, the tablet doesnt reconnect to wifi when I power the screen on. It just sits at "scanning" forever. I have to manually toggle wifi on/off to get it to connect.
Right now, I have it set to keep wifi on always, but I dont like doing it that way because the tablet dies to quick. Before I had it set to "Never" and didnt have any issue.

I have the wifi model and it has been doing the same thing since the ICS upgrade.

Well, glad it's just not me.. kind of annoying that it does this
Maybe Ill try emailing Sammy and letting them know.

My wifi is still working, it just seems to be slower. Everything seems to run slow and sluggish. It was way faster before the update. I am using stock, have not rooted yet. I update via wifi. Any advise?

I'm having a variation on that. I have the 10.1v and was just updated to 4.0.4 OTA last week. Since then the WiFi will not turn off no matter what setting I use whereas it worked fine with Gingerbread. I don't usually use a SIM card with it, but putting one in had no effect. I'm sure the WiFi stays on as I can ping the device.
I'm not tied to a carrier so I have no 'supplier' to turn to and Sammy isn't too good on support.
Anyone any ideas?

Sorry I should specify that I'm referring the to advanced sleep options only. Perhaps not so obviously, turning WiFi off does indeed seem to turn it off.

I have exactly the same problem as the OP. Both on my GTab 10.1 and GSIII. And Samsung help is absolutely terrible. I tried to resolve another issue with them, it's near impossible to find anybody coherent there. I'm starting to hate Samsung.

Wifi Improvement using WEP instead of WPA Galaxy note 2

I havent had the best wifi experience with my note or my note 2. Hoping that the note 2 would be better I was a bit disapointed to find it was still taking ages on youtube constantly buffering and generally getting on my tits I found with my note1 changing the wifi frequency in wifi advanced options from Auto to 2.4ghz helped a bit but this option has been removed as far as I can tell in jellybean so I was stumped.
After googling my problem for some time it appeared that WPA2 security on my router could be the culprit. I would have thought that a new device like the note 2 would have no problem with any of the well known router security options but after changing my homehub2 from WPA2 to WEP128bit security my wifi problems have completely gone.
My phones wifi is now fast and reliable with what seems like a stronger signal.
I dont see anybody reporting wifi problems with the note 2 but I did have and it turned out to be my router security settings so this maybe something to try for anyone having issues with home wifi.
I dont believe this to be a note 2 issue but possibly jellybean could be improved to cope with router security better.
I tryed 3 routers over a year and it turned out to be just a setting ... Doh!

I won't try because WEP and 802.11n are not compatible

Well nice but I don't think it's worth risking security.
this is SPARTAAA

Some suggestions for poor wifi.
- disable bluetooth. It's been shown that having bluetooth on will slow wifi speeds on this device. Having bluetooth connected and streaming audio makes some people's wifi slow down to dial up speeds.
- of possible, use 5ghz wifi. This will reduce your wifi signal strength, but will help illuminate the problems caused by bluetooth.
Hope that helps.

i think Samsung broke WPA2 compatibility in 4.1.2 update

there also is an issue with YouTube and wired connections. even 240p videos wont load, but its only certain servers. what I have found so far is the ones that on a whois lookup say Google is the owner have the issue. those that say YouTube are OK.

Man so much noob disinformation everywhere....
WEP is a encryption algorithm , 802.11n is a WiFi protocol standard and yes they are compatible.
5ghz in WiFi has a much higher transfer speed then 2.4ghz but at a cost of shorter range.

yup.... WEP can easily be cracked with Backtracks but if your router has WPS enabled Reaver can get your router to cough up its WPA password in a few hours.

Your problem could be with your router and not your phone.

Theres two encryption options with wpa2 personal, try the other one. It is know that some chipsets do better with one, choices are TKIP or AES, you might be currently set to both, try forcing your router to one or the other and compare them sppedwise

OP, you haven't listed your router. I know, as a fact; that the BT Home Hub's (BT provide as default, and it's what I'm using) are the worst piece of **** to have ever been included in their packages.
Try changing to 5.0Ghz, but make sure your other devices are compatible, otherwise they'll cause the router to revert back and decreasing your transfer speed.
No, WEP and Wireless 'n' are NOT compatible, don't believe me? That's fine, try it out for yourself.
There's also numerous threads on this issue, as well as other Galaxy devices.
There are far too many variables to include 'fixes.' What works for you, might not work for me and vice versa.
Grab an app called WiFi Analyzer from the play store, see the surrounding routers and check what channel they're running on.
How channels work, is that they have an overlap of 5 channels. For example, channels 1-6, 6-11, 2-7, 7-13 etc, etc.
As the routers compete for their selected channel, interference happens which diminishes the signal as well as the throughput data transfer speed.
Do some research

hey
for full speed on WiFi n you should set you security to WPA2/AES it is only one fully compatible with "n" and will work on full speed
My router is set like this, 2.4GHz, and work like charm

I have WPA2 in my house, and I don't have any issues. I get the full speed of my connection to my phone :s I know this can be an issue with certain routers though. What brand router do you have?

Like I said before WEP is compatible with 802.1n.......but some crappy home routers may deprecate it.

S4 will not automatically connect to 5Ghz Wi-FI Network

Anyone experiences this bug with the GS4 too?
When I toggle Wi-Fi off and on, it does not automatically connect to my 5GHz network. Instead, it just says 'Saved, Secured'. I must manually select the network before it connects to it.
However, for 2.4GHz networks, toggling Wi-Fi off and on will automatically search for a 2.4Ghz to connect.

Anybody?

OK - just solved it. Go to your router settings for the 5GHz network and change the channel from "Auto" to 36 or 44 - both are reportedly working fine for another reported Samsung glitch but I'm guessing the real problem here is the "Auto" setting. Hope it helps.

Wow! Thanks! Now it works like a charm. What is the reported Samsung glitch btw?

Worked!
Thank you. The problem for me was on my GS3 (d2spr). My 2.4GHz would connect but the 5GHz would stay saved and not connect.
All the recent Roms that I flash have this problem. When I flashed back to the older roms, the 5GHz worked fine. Changing the channel worked.

Wireless RT-N66U N
Thanks I have been having problems with my Galaxy Note 2 not auto connecting to my N 5Ghz working 100% now from changing setting from auto to 36 or 44 awesome

Turns out it's because of this:
k1mu said:
There's a better fix for this.
In /system/etc/wifi there are two files:
nvram_net.txt and nvram_net.txt.us
The installed one is for Great Britain, and the other one (.us) is for the United States.
Rename nvram_net.txt to nvram_net.txt.gb and rename nvram_net.txt.us to nvram_net.txt
This makes two changes. changes "ccode" to "ccode=US" and adds "regrev=5".

The above method worked for me, but I experimented and found a possible better solution:-
My Talktalk router uses the same SSID for 2.4 and 5 GHz bands. I tried changing the SSID for the 5GHz band by adding "5GHZ" to the end of the name.
The phone fails to detect the SSID when scanning for networks, however if on the phone wi-fi settings page I scroll to the end, click Add a Network, manually enter the new SSID, select the correct security method and enter the password, the phone connects.
Thereafter, if I turn wi-fi off and on, the phone then always connects automatically to the 5GHz SSID.
Both SSIDs are now displayed in the list of networks previously accessed, so I can switch from one to the other if needed.

I would hope most people would have tried that long before coming to the forum to complain about the issue.
The issue is WiFI closing & not auto signing back in whether mobile data is on or not.

It's simple option is in settings wifi

Yes the switch is simple but has nothing to do with the "closing WiFi" issue some are experiencing.

BUT I DO NOT KNOW Enabling this option AS MANY PEOPLE WHO HAVE THE FOLLOWING HAVE SOLVED MY GUIDE

unchecking this doesnt do nothing....im sitting across from my router and its telling me my signal is weak.
Browsing on vzw 4g lte is faster than my 50mb comcast wifi connection? lol if i browse with wifi its a slow lag.

Same for me. Moreover, with the new firmware, if it loose the connection while the option is unticked, it says that it will be re-ticked automatically...
This WiFi bug is really annoying.

My phone has stopped dropping the connection & is behaving well. But I have no idea what solved it. I factory reset router & phone. But it made little difference but after a day it's behaving perfectly & it's currently on my wifi & has not dropped for 12 hrs & no more constant pop up messages.
I have no idea what cured it. But one thing I did last night was went to play store & updated every app on the phone.... maybe there was a conflict in one of those apps.. that's all I can think. I left "adblock" off this time as that routes wifi data but I'd removed that several days ago.

I'm curious what Access Point you are using and how old it is? Are there firmware updates for it that you have not applied?

I've read somewhere that cancel all existing WiFi connections and make them as new (with the new firmware), could be of help. I'll give it a try.

Wifi problem
I've tried all the solutions on here,and nothing works. Very poor samsung for such an expensive device. If a £30 roku box can have perfect wifi why can't a £600 device

I must admit that wifi performance is quite poor for the moment.
I get 6 or 7 Mb/s out of a 25 Mb connection. My S4 , Note 1, and Ipad 3 al do around 20Mb/s while testing simultaneously

You can probably find what it does on the Internet (Google), but it doesn't truly help. My guess is that these performance issues are router dependant. I'm waiting to get my hands on the new Asus RT-AC68U router to upgrade my yesteryear 300 mb/s router. In fact I just ordered it, it will arrive tomorrow. Will post here to let people know if it helped...

Well I was right, my shaky Wifi connection using my Sitecom WL-351 router is a thing of the past. Both the 2.4GHz and 5GHz connections through my brand new Asus RT68AC router work excellently!!
What this very probably means is that the Note 3 uses a Wifi chipset that doesn't work all that well with certain other (older model?) router chipsets. The Asus I bought to test this is quite expensive, but I am sure a regular router can work well given it is compatible. What needs to be done is verify (through a Poll or by researching known chipset incompatibility problems) what chipsets and/or routers / brands work well. Unless you expect Samsung to fix this in software, which often is impossible - unless Samsung can force an update of the chipset firmware.

Unfortunately Brand names don't mean compatibility since various models use varying router chipsets.

Anyone's WiFi disconnecting randomly?

I've only noticed it on 5g but it may happen in 2.4 also. Using a nighthawk router with no problems elsewhere.

Nope, Wi-Fi has been flawless

I have been noticing this happening several times a day at work and at home. I am sitting 20 feet from my router at work and it has disconnected 2x in the last 5 hours. It will reconnect. Same thing will happen at home and I am sitting even closer to my router.

I've had 1 random reconnect that I've seen having the phone for less than a day.

Supposedly an update for this rolled out today. However I haven't had any issues.

I know I was having the problem, but found out it was because I enabled the my places tab on the edge panel. Basically it was turning off WiFi when at home. I was paying with the tabs, turned it on and forgot about it.

I'm wondering if it is bouncing between 2.4 and 5 ghz bands causing the disconnect. At work we disabled the 5ghz and my phone is fine. At home both bands are enabled and it seems to disconnect and reconnect when I get a certain distance away.

Definitely try this. I have two cable modems and two routers. The routers are identical and the cable modems are different. On one modem/router set, the IPv6 address is passed along perfectly and have no issues. On the other set, the cable modem doesn't get assigned an IPv6 address properly and I will get wifi disconnects, non-working Google Play, etc. Once I shut off IPv6 on that router, both networks work perfectly.

I have Fios and the router is set up with both bands having the same ssid and set up. Works fine with my laptop and tablets. IPv6 is disabled by default. So my only thought is that as I get upstairs and far enough away, the phone is disconnecting from the 5 and connecting to 2.4.
