@azulpiscina, you have to click the "Mount R/W" button at the top right of root explorer screen before you can edit files.

Trying, back in a minute with feedback.
thanks!

This ended up not working for me either. I have had this issue with this phone and others and it seems to come and go, raising it's ugly head again when I went with CM7.
I had a D-Link DIR 655 router and last night I replaced it with a TL-WR1043ND and so far the issue is gone. Signal strength is much better too.

Ive had no problem

Ive had no problem whatsoever with wifi on any cm7-rom ive installed.
Ive had rc1 and many nightlys installed and never had any issues with wifi.
My router is a Linksys wrt320n with dd-wrt software.

It didn't come with it but I flashed the new router with dd-wrt. I have not had any wifi issues since.
I was reading on the dd-wrt wiki about the N specs and discovered there is a setting in the old router that may fix the issue and also explains why some people have issues and some don't.

I installed CM rc 1.5 and I have a Linksys WRT54G at work (with dd-wrt) and one at home (original software), and i'm having this wifi disconnect issue in both.
I have 2 defys, the other running 2.2 and it's amazing to see the difference in the signal strength of the two ROMs running side by side.
I just tried deleting the file /data/misc/wifi/wpa_supplicant.conf and reboot (from this thread: http://forum.xda-developers.com/showthread.php?t=1161460&highlight=cm+wifi) in the last 10 minutes and so far so good, but it didn't seem to fix it for someone else in that thread in the long run. I'll report back here if it fixes it.
Update: That tip above didn't work, but now I'm using 110927 nightly and I don't see the disconnect issue anymore, and the weak signal seems to be gone too.

I also had wifi problems, always disconnecting. I found in the official motorola forums someone saying you should search in the router settings for an option called wmm or wme (windows media extension) and deactavate it. also use tkip instead of aes. im running cm7 rc 1.5 with a dlink dir 655 router. it solved my problem. didn't have any dissconects the last days.
hope this helps someone

Problem is, there are wifi issues in CM (at least for some people, like me). I don't have any problems in 2.2, with the same routers I always connect to. So I would guess we need to find what could be changed in CM to fix this issue, although I understand that changes in the routers can alleviate the issue.

Anyone knows where's the cfg of the wireless strenght icon on the top bar? I wanna change the value of the 4 stages.

i agreed with bra2006. it should be fixed in cm7, and not expecting any everyday users to muck around with their modem settings to get around it.
if some roms don't have problem, why should cm7? surely they can compare and work out why cm7 has problems while others don't.

I also have the same problem, with RC1 was ok, when I put RC1.5 began to disconnect the wifi

LTE wifi anyone?

THANKS SO MUCH!
This is from my laptop tethered...

From the development thread (can't post a url yet since I'm a newb) there seem to be a few bugs:
Widely confirmed is that total data use since last reboot is reported, not session use.
Some people have reported random reboots after shutting down tethering.
Mixed success in setting up a secure wifi connection.
All that being said, I am incredibly happy to see development on the LTE version moving ahead so quickly.

I'm getting this message when running it, and then a force-reboot. Hopefully it will be fixed soon.

Now if only they can get it to work in ad hoc mode. Yeah I know its not as good but I need it at work.

Did you set your device profile as Samsung Galaxy Nexus LTE? It works fine for me.

Everything worked for me just fine on LTE Galaxy Nexus after setting the profile to the correct device. Haven't tried encryption though.

Sorry if this is a stupid question but does this let you tether without having the data plan for it? Is there any chance Verizon can catch this?

Yes and No!!
Have fun!

Work great; no issues at all. Thanks!

Thank you!!!

Froze up the first time I tried it. Wiped everything and reinstalled Android Revolution (not due to the tether issue) and tried it again with success. Thank you!

Restart on stop
Does anyone else have the problem where your phone restarts after stopping the tether?

My wifi tether keeps crapping out after about 10 minutes with security on, works fine without security. Is this a known issue?
---------- Post added at 10:01 AM ---------- Previous post was at 09:24 AM ----------
Am i the only one losing connection? I just downloaded ~300 mb of a file and then I see a message on my phone saying "Wifi tether has been granted SU permission" and it shut off. Is it something to do with the screen off settings? Or my SetCPU being clocked at 350mhz when screen is off?

This happened to me today. I ran it for the first time today. Once I turned it off, my phone started the cycle with the Samsung startup screen. Once it was back on, I had no data connection. I thought the tethering app busted something, but it turns out VZW is/was having a massive 3G/4G data outage at the same time.
Anyone else have this restarting issue? I'm probably not going to run the wi-fi tethering app again if that's going to happen.

Works great here. Thanks!

Very nice and has worked perfectly for me. I'm suprised this was not on the first page of the App forum.

if you use WiFi usually.....it saves battery, and keeps WiFi connected until you disconnect it....
and does not toggle to your 3G/4G Mobile Radio when in sleep mode...which then has to toggle WiFi on again.....
It might work!!

omg... i have the problem too. i was using bionic cow. last night i flashed the black notes but later i restored bionic cow and the settings using cwm. and wifi totally didnt work. oh no
psh.... sorry it was the router's problem (woah what coincidence..)

I've just started getting the same problem since updating to the latest stock update. Thing is just after I also changed my router so not 100% sure if it's the phone or the router. My WiFi is ok but after I've not used it for a while I have to stop and start it again for it to work (the phone not the router).
When you say it was the routers problem what did you change in your settings? I've looked into mine and can't see anything that would cause it to disconnect the phone and my phone is set to 'never' disconnect in sleep policy.

i suppose this happened to me quite recently.
try having your network either on wcdma ONLY or GSM ONLY.

Thanks for the reply but I've sent my phone back to Samsung for a cleaning as it had dirt collecting under the screen. I mentioned on the return form about the Wifi so if they get back to me on that I'll post what they said.

Got my phone back from Samsung. Have to say great service. Sent on Tuesday and back repaired on Saturday. The WiFi problem was also sorted. They just put a note in saying 'We've installed the latest approved software as part of the standard repair service'. Funny as I thought I had updated to the latest just a few days before sending it off. Phone reads:
Android Version: 2.3.6
Baseband Version: I8150XXKL3
Kernal Version: [email protected]#3
Build Number: GINGEREAD.XXLA2
I'm in the UK so if anyone else is having this problem update to this and hopefully it should fix it.

WiFi Connection problem. ( Network Disabled. Poor connection)

The weird part is it says "Network Disabled. Poor connection." but the bar is strong. It has always worked up until the last 24 hours. No god damn google-ing was helping. It is set to wpa/wpa2 PSK.
What the hell is wrong with it. The 4glte works. I haven't downloaded anything obscure.
Provider Telus.

Wow, I now have the exact same problem with my SGS3 (international version without LTE). I already tried "forget this network" on my phone and "delete this device" on my router but it still wouldn't connect.
I installed the official JB update a couple of days ago. Never had that problem before.
Edit:
I could fix it by disabling DHCP and instead assigning it a static IP in my network. Though it is still a bug because if I'm in someone else's network (e.g. Starbucks) I usually wouldn't be able to use this solution.

Okay, it stopped working the next day and now everything I try, I can't get WiFi to work.
****ing piece of **** phone. Since the official Jelly Bean-Update (my phone is not rooted and no custom rom or whatever) several things stopped working. My ****ing Google Calendar just won't sync anymore (says "sync is currently experiencing problems, will be back shortly" for 2 weeks now), ****ing WiFi stopped working. I'm really pissed right now, mostly because I didn't customize my phone for exactly those reasons!!!

Honestly, what were you expecting? touchwiz is notoriously known for being absolute trash. None of the issues you've brought up occur on custom ROMs. Bite the bullet and flash one already.
Sent from my Galaxy S3

My solution for "Network disabled. Poor connection" problem.
I had exactly the same problem today (SII, ANdroid 4.1.2 - Samsung leaked) but the history was a bit different. After the flashing all worked fine for several days. Today I upgraded my WiFi router with the new firmware (before I used the 5 years old one) and on my Droid the problem occurs. What is important, I got 3 devices in the home network: my Samsung Galaxy S II I mentioned, and 2 others - HTC Desire HD and Galaxy Ace - both with tje Android 2*. WHat was strande, only HTC worked withut any problems, both - Galaxy and Ace stopped connecting to WiFi.
I read a lot of posts, i undersand that the available solutions are: static IP (not acceptable, I need to connect to different WiFI networks every day) or rooting phone and clearing DHCP configuration on the phone (not available without root, as in my case). But - because everything worked ok before, without any changes on the phones (!) and as I read in the posts the problem is network-related, I decided to find the issue in the router configuration. So I cleaned the conf. of the router (reset to thefactory default settings), removed the information about my network from the phones, connected my phone to the "Clean" unprotected WiFi (default WiFi set-up after the reset), and then step-by-step added more security configuration on my router. First - changing the WiFi SID name, through the wireless mode (AP), then network mode - from B to Mixed, and then security modes WEP, WPA, WPA2 and algorithms: TKIP, TKIP+AEP. After every change on the router (several router restarts needed unfortunately) i tried to connect my phone to the WiFi. Finally I added the MAC filter. And... everything works OK! :laugh:
I propose to test the same solution. In my opinion the phone will connect without any problems to the unsecured WiFi, then one can find which step, which area of the config cause the problem - if it is solved when setting the mixed network (B/G) or maybe some of the security algorithms are not accepted.
I know that in fact it is not the fastest solution, but in my case the problem was solved - I got the same security level and settings as before when I had this error! Probably the changing settings of the connection which must be aplied by Android, do quite big 'revolution' in the DHCP conf. files of the phone, and the result is the same as after clearing the folders after rooting.
I hope my solution could be helpful!

No need, mine works fine...

I have exactly the same problem. Started right after the 4.1.2 update (SGS3 international). Unable to connect to any secured WiFi. Always the same: connecting -> authenticating -> obtaining IP address -> disabled (and a popup about poor connection).
Sometimes it does connect if I reboot or first reboot after factory reset.
Tried about 4 different routers. Factory defaults. Still the same.
I guess it's time for an unofficial ROM...

Stock JB ROM? Router model? 2.4 or 5Ghz?

I had this exact same problem, I had 4.1.1 and I odin flashed to 4.0.4 thinking it was the JB update. I found out that my Wifi password was off by 1 number and instead of the phone telling me my password was wrong it would throw that error at me. As soon as I double/triple checked my password and entered the correct one, my phone has been working fine ever since. I am on stock 4.1.1 JB.

Did anyone find a solution to the Wifi Problem on 4.1.2?
Regards

I think i found a fix, for some!

Some routers can broadcast on both frequencies simultaneously with different SSID's. I know newer Netgear routers do this.

notes on my exact situation
-wifi works fine on many open networks and private networks for both myself and my gf (both using galaxy s3 phones)
-the specific network is a private network at a business (my gf is the owner of the business so we have access to the router and its settings)
-we have both previously connected to this network before without any issue.
today neither of us could connect to this network. we restarted our phones, the router, "forgot" the network, and eventually gave up.
This is very frustrating as we both spend a good amount of time in the business (coffee shop) and it seems that no one else has connection issues, not other phones, not laptops or tablets, not anyone else. Both of our galaxy s3's just keep coming up empty on this one network.

Help!
I have the same problem after root my i9500 with CF-Autoroot on 4.3.
Already tried everithing but after some time from root it lost connection and can't connect again, even on other router.
With 4.2 always worked fine. But now, if I do the root process the wifi works only for 5 minutes.
It start with the first 4.3 update, but even now with the last 4.3 I9500XXUEMJ9 I can't root.
The "Network Disabled. Poor connection" is the only problem, everithing works fine. The root is ok. Knox freezed.
But now I have to flash the stock firmware again to get wifi working. That is the only solution (remove root) until now.
Any help?

slowed data an hot spot after newest update

Has anyone else's data and hot spot slowed way down to where they barely work after the ARI4 update on the SM-G960U? Nothing will load on chrome or most of my apps and hot spot is useless. I've tried updating the prl/profile, a soft reset, clearing the cache and changing the preferred data to lte/cdma and nothing has helped. I really don't want to do a hard reset. I'm on boost mobile but the other two phones' data work just fine.

ok it worked for a while now i'm back to the same issue. data buffers/cuts on and off, it cut off completely yesterday and 5G wifi no longer shows up. (been that way for a while). boost was no help whatsoever and the morons kept telling me that 5G data isnt out in my area yet. um, i said 5G wifi.. plus i got disconnected 4 times in two hours of chat. i'm done with that

get the latest firmware from sammobile.com and flash it via Odin. There are 2 CSC files to choose from, one of them factory resets, the other just applies the update. Use the update one, and go from there.

As above, update your firmware, you can use the U1 firmwares without the carrier bloat too to get the latest release

Factory reset is sometimes the only fix though

I messaged them through Facebook, as they told me to do and it was still useless talking to them. They completely blew off the fact that my data is wonky and it was cutting off. Typical of them though.
Unfortunately I don't have access to the router, it's a shared network for where we live. I've asked them to reset it and they did but it still didn't help. All my other phones are picking it up so it has to be this phone.
I'm on an U1 firmware now and the same thing. Not just that when I use the phone now it gets stuck in it. I'll hit home and nothing, just the phone screen until I restart it. I tried to go back to U but I get stuck at "file analysis" for some odd reason.

If you did not reset after flashing the U1 firmware I'd suggest backing up and factory resetting then

COMPLETELY forgot to factory reset... I'm an idiot. Thank you!
