Turning it off then on again usually does the trick

Wow XD it worked. Thanks! MAn ics is awesome on tablets!

and you were too lazy to try that on your own or look it up here in the threads, dude you should be banned from xda and even using any type of smart device

If you are in charge of the router, set it to a low channel (1-5 or 1-6). That solved my problems.
If it does not, there are more discussions in the forums, although in my impression some of the recommended cures are rather "obscure".

what are other ways?

My wifi worked everywhere but my house, which used WPA2. Once I changed that from AES to TKIP encryption, it connects smoothly every time.
There are new drivers some people are using, but they don't sleep correctly, and you'll lose battery a lot faster. It's pretty much going to be a trial and error process to figure out what works for your setup.

Try while wifi on, forget the network -> turn wifi off -> turn wifi on -> connect to the network again. This shoud work but have to repeat everytime you reboot your tp.
Used to have this problem, i install different kernel -> back to original kernel boom. It works

AES is much more secure than TKIP - which has known vulnerabilities and can be cracked much easier.
A few more things to do to help:
- Set your router to one of the lower 6 channels
- Set your router to use AES security only,
- Set your router to use wireless mode G & N (or G Only, if you have B but not N - this will allow for it to use N if possible, but everything else that isn't N can use G as well)
- Go into Wireless => Advanced settings on your tablet, and set your Regulatory Domain to 11.
Then reboot your tablet, remove the saved network you had, and reconnect to it. You should be good from then on out. My tablet has zero problem reconnecting with these settings, on four different router setups (Telus Optik all-inclusive, D-Link stock, Linksys stock, and DD-WRT customized).

(solved) note wifi disconnecting :(

Hi all. i have a problem with my note. on some instances if i try downloading large files(for games or navigon maps, or just browsing on some sites, etc) after 10 15 seconds the wifi adapter shuts down/resets and the connection is lost. the adapter restarts and connects to the wifi in 2 3 seconds but is very frustrating to try downloading something many times before succeeding. anyone else has this problem? i searched the forum but didnt find anyone else with this problem. any ideas as to what is causing this problem?

Re: note wifi disconnecting
Hmm. Try changing the router wifi settings to transmit only b/g and retest.

Had the same issue, please tell us what version and kernel rom you are using?
->I had only when using CM, on stock GB and the XXLSC roms, I did not encounter this problem (also with cm 10.1 I seem to have a stable connection again)
**I do want to note, that it can't be possible to have a worse connection when on CM vs TW, but I have experienced it this way. So I can onlyh draw my conclusions from that...(I don't have any developer knowledge whatsoever)

Re: note wifi disconnecting
I would start by un plugging the router and plug it back in.

Re: note wifi disconnecting
baseband version: N7000 xxlpt. kernel version N7000 xxlq3. android 4.0.3. This issue was present from day one. but never tried downloading large files from another router and my htc legend never had this issue with the router. will try to see if the router is the problem today and get back to you. tx to all in advance

Try this:
Dial *#0011#*
Press the menu button on service mode screen
Select wifi
Turn "wifi power save mode" off
It seems like this is only working on samsung roms. I'm on CM10.1 and I have to dial *#*#0011#*#* to access the service mode.
Also there is no wifi entry in the menu.

Re: note wifi disconnecting
just downloaded a 700 +mb file with no problem. i set the router to b and g only. seems it was the frickin router. tx a lot to all 4 ur support.

CHanging to b/g works
Hi,
I have router DIR 855 and had the same issue with my note. Wifi kept disconnecting whereas all the other devices at home stay connected. So it was clear that Note was the one that had the issue. Changing the 2,4ghz to b/g setting helped but I would like a stable connection on my 5 ghz band and that one keeps disconnecting. Any idea how to fix that? I am using NAS and the speed is much better when using 5ghz instead of the old crappy 2,4ghz.

For me too 5GHz is not stable on note... Why not use the router on Auto and then use the settings on NAS to use only 5GHz

Please explain

Hi,
Can you please elaborate on how to do that?
My router has two different bands and it cannot switch between the two. What do you mean by NAS setting?

Depends if your router can run simultaneous dual band.

Wifi connecting... saved... obtaining ip address... saved

I'm wondering if anyone running either cm 10 or Pac roms is having issues after a few weeks, of wifi attempting to connect then saying saved and doing that over and over again and not connecting. I know other people not necessarily using this phone have had this issue before but, I can't seem to find any solutions to the problem. I am currently running Pac all in one Rom and it was working great until today but, I have had these issues on cm 10 before and the only thing that seems to fix is to flash a new Rom and I like this one and don't want to re-flash.

I always get this issue on custom ROMs
Sent from my MB886 using xda premium

I've been having this issue as well, again and again.. I've had about a 50/50 success rate with dirty flashing. Anyway, I believe the problem has something to do with the dhcp assigned ip addresses from the router. It's something on the phone side of it because changing dhcp settings,lease times etc., on the router have no effect. When you lose WiFi and it goes into that loop and won't connect, go into WiFi settings, and forget your network. Then select your network again and enable the advanced settings. Change from dhcp to static and then assign yourself a local IP. I have a Linksys router so I entered 192.168.1.8 . so I believe a netgear router would be 192.168.2.?? , the ?? or 8 being whatever is unused on your network. If you haven't already, enter your password and connect. I connected immediately after that. I understand this isn't really a "fix" because won't help you when trying to connect to networks that you can't assign your own IP, like say Starbucks or somewhere.. But hopefully this may point someone who knows more about this stuff in the right direction to actually fix whatever is off in the phone. Drivers maybe? Hope this helps!

Thank you for the explanation I tried a dirty flash and that solves it for about 12 hours. I am getting faster at flashing and restoring everything and am now flashing a new Rom every couple of days so it's not that big of a deal I'll just take it as a sign I should try a new Rom I'm now running the unofficial aokp Rom and I'm liking it next time it happens I'll just try another. Thanks for all the help glad to know the issue isn't because I've done something wrong.

Is there anyway to fix this issue yet?

@TTLayland said exactly what I'd say...static IP. I'll add the the Devs are working on updated WiFi drivers for the kernel. When that's ready hopefully that'll work for ya'll. I haven't had any WiFi issues for the past few weeks. Connected to my House, McD's, and the hospital.
Post the actual make & model of your router and I/we'll see what can be found for it.
Also, try setting the phone to 2.4 Ghz only...my old router was 2.4ghz and the auto setting would randomly kick me. New router broadcasts in both 5ghz and 2.4ghz, I connect to the 5ghz one and use auto without issue.

a lot of the times I have to log into my router and turn the security completely off and then log on with my phone get a connection and then log back into my router turn the security back on and then I'm good to go.
Kinda like the flashing back to ICS to get a GPS lock to work on custom jb ROM's

Ok, I didn't realize Devs were working on it. I have statics set for my home, but being a Network Admin I travel to many different networks and because of the way our network transverses settinig an ip is not an option as the same SSID is used for about 95 different sites. So DHCP is a must.
I just thought it was strange that the Carbon rom I am using was working for about 2 weeks correctly then stopped connecting, sometimes a reboot will get it to connect.
Thanks.

I wish it would work I just gave up on wifi on ahd if using custom rom

WiFi Problems, help!

So for about a week now, I've been having horrendous wifi issues on my device running CM 10.1 nightlies. My problem being that my phone will remain connected to wifi but no actual connection is present. It's very sporadic and highly annoying. After the problem occcurs, it still says i am connected but i can't actually access the internet.. Temporarily disabling wifi and re enabling fixes it for a couple minutes then it happens again. I'm pretty sure it's not a hardware issue as i can use my school wifi for an entire day without disconnects or anything but i can't get mine to work. I've tried carbon rom, diff nightlies, clear data+ cache but nothing works. This also happened on an xperia running CM (my dads). Any solution??

So the issue is on the router side, do you have a dual band router? if so make sure 5ghz is up and running. If you have a single band router thats capable of 5ghz, make sure all you wireless devices are capable of 5ghz freqency and if so switch it over.
Also Ive fixed this/ or similar issues on networks by disabling QoS in the router settings, id recommend disabling it and see if it helps

The strange thing is I haven't changed any router settings at all and before last week I've had absolutely no issues with wifi. Now it seems I can't keep a connection for more than a couple minutes max. Also, sometimes (not always) I'll try connecting to a different router or access point and it'll connect and the next second it'll instantly disconnect. I'll try your suggestion and hope it works

[Q] Issues with WiFi

Guys, since I've bought my razr I, I have this terrible issue with wifi connection. Everything works perfectly normal, but when I let the phone idle for like 10 minutes, it's like the wifi drops the connection. The device tells it's still connected, but I get no push notifications and no navigation either. It only happens when I'm at home, and the most affected is the whatsapp. Anynone has any information regarding this?

if it only happens at home as you say it seems to be more a problem of your router (settings).

Have you got any idea of what settings I should look? Here I have an iPhone and blackberry and both have their wifi working like a charm.

Updating the firmware of your router would be the first thing to try.

Set your WiFi connection to 2.4ghz only (on your phone) and deactivate the 802.11n standard (on your router). In my Fritz!Box, i had to chose 802.11 b+g. The razr i doesn't like the n standard, although it "officially" supports it.

My Ri runs on 5GHz only like hell
