I'm running Dexter's mod. When the A7 goes to sleep, it loses its wifi connection at wake up.
I have to go into "Wireless and network settings" to turn wireless on, and then the A7 gets stuck in the "scanning..." mode, even though I have a real good, strong wifi signal.
I toggle the on/off wifi several times (about 2-3 minutes of playing), and eventually the A7 sees all the available signals and connects immediately to my home network...
I really want to stop trying tablets, but the A7 is really testing my resolve.
This has happened to most everyone that flashes Dexter's mod. It has to do with wpa_supplicant though honestly I don't know the root of it.
Another forum member replaced the file with the original that shipped on the device after he had market enabled and the problem stopped happening and he retained market access.
I'm running 1.0b and haven't had the issue since I flashed it.
Have you installed Dexter's ad-hoc hack? that causes this problem to aggravate. If you have the wlan and wpa-supplicant files from 1.0c (System/bin) you will be fine..
I am running Dexter's 1.0c and upon re-awakening, it connects right back up with no problems. The only issue I have is not being able to keep the wi-fi connected when the unit goes to sleep. I don't want to keep the screen on 100% of the time as this really sucks the battery down fast. I have tried 5-6 apps that are supposed to fix this, but so far no luck. Anyone else been able to keep the wi-fi connected when the tablet goes off?
I had the same issue until I changed to this supplicant. Now no problems.

Thanks, Craig118. Did you have to install the same as Dexter's mod and wipe all data, or does it install without deleting files?
Just copy and paste that wpa_supplicant into your sys/bin folder. That was all I needed to fix mine. Two weeks now with no sleep /wake issues.
Craig 118:
Thanks for the help, am just getting around to trying this. I have copied the Supplicant.zip file onto a USB stick and have tried to copy to the system/bin folder but keep getting an error message that file cannot be copied. My /sys folder does not have a bin subfolder. Any suggestions? I have copied files from this same USB previously.
Have now copied onto my sd card, and still get the message cannot copy file. Anyone have any suggestions?
Are you using root explorer? You have to change it to read/write in order to overwrite the file.
I am using the standard OI file manager on the machine.......
That app. will not work. You need superuser permissions to change sys files. Download/Install Root explorer and use it to copy the file your sys/bin folder (must click on write).
adhoc connectivity worked on galaxy s2
this trick found from another thread
you need a rooted phone & root explorer
1. Unzip the file attached here (wpa_supplicant.zip) and send wpa_supplicant to your phone.
2. Using Root Explorer go to the folder were you save it (wpa_supplicant) and copy the file.
3. Using Root Explorer, enter the /system folder and press the Mount W/R button (upper right corner)
4. Now go to /system/bin and backup your current wpa_supplicant, and paste the new one.
5. Set permissions to wpa_supplicant like attached picture, then go back to /system and press Mount R/O (upper right corner, so you leave everything exactly like it was) and reboot. Done. Enjoy AD-HOC!
Thanks for the patch, but before you get banned by some moderator, please remove your first attachment. It's a paid app/ WAREZ.
Root Explorer is paid. Don't post it.
Tested & working on sgs 2! Thx man!
I can see the ah hoc network established from my laptop now.. but when I try to connect, it stays in a state "Obtaining IP address" .. so cannot access internet anyway .. Is there any workaround? Thanks.
Thanks dude
excellent, previously i was using connectify to connect my phone to Laptop but the signal strength was so poor and also after few mins it is used to go down. Now got rid of the problem using this file.
Thanks again

+1 for me too.
P.S. just replaced the original file using Root Explorer.
hi,
the same here that varunmagical with VillainRom 2.4.2.
gs2 is able to find adhoc network but cannot obtain an IP.
very much thanks if you can find a solution...

Thanks a lot
it worked for me.
I replaced this file. This step is important:change the WPA to WEP encryption mode on PC. AD-hoc is ok using my SII I9100 mobile.Pls to try it. tks.
still not for me despite the wep ad-hoc network created from the mac.

what are the permissions to set?
is it important to switch back to Mount R/W ?
thank you
i have a tablet running android 2.3.3 rooted with superoneclick...i follow the instractions to copy paste the wpa_supplicant using root explorer.but when i open my wifi shows false and my table restarts.what i do wrong...i am lucky that i made copy of the original file
I´m actually able to see network but not to connect to it, any advise??
I take it this is not ICS / CM9 compatible ??
Galaxy S II
CF rooted stock 2.3.6
Working in free and WEP modes.
But there were problems with WinXP configuration.
(In wifi network first have myself to connect to created adhoc network, only then phone sees adhoc network)
Galaxy Note's WIFI VERY unstable after replacing wpa_suppliant.
I wanted to connect my galaxy note to my iPad's Mywi for wifi (ad hoc) connection.
Thus i did the following steps:
- root galaxy note using zergrush
- downloaded xda's replacement wpa_suppliant
- downloaded root explorer
- uploaded the replacement wpa_suppliant file to the phone and replaced the original one at /systems/bin
After this, my phone was able to connect to iPad's Mywi, BUT connection is VERY unstable and gets disconnected every 5-10mins. Also it takes really long to get it connected back, like about 10-15mins for it to try to get connected.
I've tried re-doing the WHOLE of the steps above, INCLUDING re-rooting my phone, but to no avail. My Wifi function was working perfectly fine prior to this.
Can some kind souls out there please advice me if I've done anything wrong in my steps? Or if there's any way to solve this (WITHOUT re-doing it back to the original)? thanks!
Hi! Recently I bought the Galaxy W equipped with GB 2.3.6 and yesterday I installed the latest january's firmware upgrade.
Did anybody try to install the modified wpa_supplicant into that device?
Thank you!

Set permissions to wpa_supplicant like attached picture? Which permissions? Can you upload that pic again or just tell us what to mark, owner group others? read write execute? And from special permissions: Set UID, Set GID, Sticky?
By default at my stock wpa_supplicant permissions are set and marked like: Owner=mark at read, write and execute, Group=mark at read and execute,
Others=mark at read and execute. None of special permissions are marked.
Should it be the same for new copied wpa_supplicant or?
Thanks in advance...
Just one little question here. I hope someone takes time to answer it. I have been around reading about adhoc this and adhoc that. But what I wanna know if these methodes that enable adhoc functionality, allow 2 mobile devices to get connected to each other. I mean like between 2 SGSII not between a PC and a SGSII?
Like making one of the SGSIIs the center and the other client (or infrastructure or whatever it's called)?? Is this possible with all these adhoc enablers?
Can't turn Wi Fi on after using the file from OP.
Using ICS/CM9 Hydra rom.
Hi,
Just wanted to find out how many people are having the WiFi disconnection/reconnection issue?
I'm thinking of delving deep into the frameworks to fix it, but I'm not sure if it is just a few devices (including mine) or more of a systematic problem.
Thanks
i had the same problem over the last few days. If factory reset didn't work it was a reflash. It works for me now but you never know when it's gonna crash out again.
currently running your 3.1 rooted rom and i'm in Sydney if that makes any difference.
had this issue with the leaked 3.1, Acer_A500_3.019.01_COM_GEN1. i'm using the new stock OTA Acer_A500_4.010.07_COM_GEN1 and haven't had that problem since i upgraded. i'm connecting my Iconia to a home router and a mobile hotspot and both work without problems.
A. if you're rooted, you can just delete dhcpcd-wlan0.lease located in /data/misc/dhcp and try reconnecting.
B. if not, you can try this:
1. Forget the connection
2. Reconnect to the hotspot, this time using Static IP instead of DHCP.
3. Assign a valid IP Address and connect.
i always do option B when i was having the issue.
hope this helps.
Just delete this file in term or root explorer whenever the issue occurs.
/data/misc/dhcp/dhcpcd-wlan0.lease

Hi, Today I unrooted Nook, updated to 1.0.1, and rooted it again, all perfect.
Then I installed Root Explorer, and pushed the wpa_supplicant on the sdcard.
Then I copied it from my sdcard to /data/misc/wifi, and overwritted the default one, I did this before and all OK, I need to do this because my university has TTLS PAP and I can't configure it from the B&N Wifi manager, but I forgot I had Wifi connected, and now, it says Unable to start Wi-fi, I tried putting again the default one, but the same happens.
I powered off the Nook 2 times but the problem still.
What should I do? Try a factory reset? I'm scared :S
PD: I rooted with TouchNooter so I don't have a backup image
Sorry for my english too xD
EDIT: I solved it deleting the supplicant and turning on wifi, it created a new one and solved it. Sorry for the post :\
EDIT2: I finally solved it, I had to add a new network from the manager, saved it, and then open Root Explorer, and edit the supplicant manually changing the WPA-EAP to TTLS and the authentication phase to PAP. I don't know why it happened, on the 1.0.0 I did the same and nothing happened :S.
Sorry for the inconvenience ^^u
Just a note, if you root with TouchNooter you can unroot with nookRestore (by ros87, available at http://forum.xda-developers.com/showthread.php?t=1289233 ) without any difficulty at all. If you ever mess anything up, it's a good way to fix things. A factory reset doesn't typically wipe everything so it's not something you really need to worry about.
another note. You can't see and connect to adhoc p2p (non access point) networks like a computer or joikuspot for tethering. Dont know why. Might be easy to enable...
Yeah I had to use nookRestore 2 days ago, I had some problems and needed a reset.
I love there's an app for tunneling by SSH your nook, so I can connect to IRC in my university
By the way, I just found out the NookTouch can only see accesspoints - no adhoc networks. So you can't connect to your computer direct. But of a bummer if on the move - you'd have to carry round a WiFi access point.
Hopefully this can be enabled.
Just thought I better let people know because I was going crazy trying to figure out why my Nook wasn't seeing some networks!
Thread to discuss how to solve wifi problems on cm7 kangs with the new kernel & wifi driver, like my kang here: http://kan.gd/1h7f
updated: wifi problem fixed, fix here: http://kan.gd/1h8g flash with clockworkmod.
problem with phone not waking up after long calls still exists, that will be fixed tomorrow.
Wbaw, I installed your latest KANG (cm-7.2.0-blade-KANG-wbaw-120225), and also have the same wifi problem, like here. (Can not post there, because I haven't got the 10 posts)
Wiped and format everything before install. It says "scanning...connecting...disconnected". I've tried everything from changing the encryption, to changing the SSID, nothing helped. I have a Linksys WAG54GS router, "G" network, channel 10 - 2.457GHZ, encryption is WPA2-PSK. Attached a logcat log from boot, if it helps recognizing what's the problem.
With other KANG and with older kernel & wifi driver, my phone connects to my home wireless network.
Thank you for your help!

I'll probably have to make a couple of test kernels for you, it looks like the new wifi driver is failing. It's either the new driver & kernel source or wifi undervolting, but I don't think it's due to undervolting.
You can also try this kernel: http://forum.xda-developers.com/showpost.php?p=22887053&postcount=92 it's the same except I removed some useless looking files from the wifi driver for the kang, they're in that package.
I'll make a couple of packages tomorrow for testing.
If you have any problems with my kernel, please use the issue tracker, open an issue there & I can respond: https://github.com/John-Kenney/zte-turies-35/issues
I will open an issue in the issue tracker tomorrow.
Right now i have to get data back from my SD card, because i accidentally formatted it...
You probably know that by now, that the new wifi driver works only with 802.11b network, so if your router was set to "G-only", the phone could not connect. Of course mine was set to that. I set to "mixed", and it connects without problem.
Can't wait to test your kernel for the GPU overclock Thanks!
Seems strange, it seems to connect at 'g' speeds for me, but my router is set to 11b/g/n auto.
It looks like the new wifi driver causing the problem rather than the kernel, unfortunately I think it's the only wifi driver that works with the new kernel source.
