[Q] Wifi and CM9

Hey,
After fresh install of FXP 128 my wifi worked for few hours, but later it refuses to connect to any wifi, because the "signal is too low" or something.. how to fix this?

Actually try getting close to your modem/router first and connecting again or if its still unable to connect reboot your phone

Already did that, didn't help.

Then CM9 probably has an issue with wifi, i guess you'll have to wait until an new RC comes out

Try this:
http://forum.xda-developers.com/showpost.php?p=28442213&postcount=2998
Delete /data/misc/dhcp/dhcp_list

I have no files in dhcp/

Another wifi problem
I was also having trouble getting wifi to work using JJ hybrid mix 3.1 + Arcknight kernel 3,3 and 3,4, had to use stock kernel
The solution from JJ'to reboot after installing he's kernel didn't work for me.
I've had cyanogenmod 7.2 installed prior JJ.
I've wanted to post this error to JJ's thread under development, but I don't have enough posts made.

I'm sorry for mistake. I used to have some similar funny situation... wifi in my brother's house is protected by WPA-PSK [TKIP] + WPA2-PSK [AES] and my arc can't connect to him router (authorization problem ?!) . I have the same router and the same protection protocol and in my home wifi works good.
(Sorry for ungrammatical English)

I'm also having a poor signal even when my router is very close to me...I have 2 WiFi routers and from both I get the same issue...I have deleted the files on dhcp folder but doesn't have the dhcp_list folder neither...
I have installed CM9 and previously had SE standard ROM 4.0.4
Any idea what to do?

Router crashing with new Jelly Time rom

Hey guys,
I tried searching and could not find a similar problem.
Since getting the new rom I have noticed that my wireless router has been experiencing connection issues. all my devices show connectivity but i dont have access to the net. Anyways i decided to have a look and the android is creating multiple Ip entries on the router with the same mac address and everytime I turn the wifi off on my phone the problem does not occur.
Any ideas?
Thanks

Have you tried going into development settings and turning of Android Debugging or ADB over network? Just a suggestion, not sure if it will work.

nah cant be that, I had them turned off already.
Thanks for replying anyway. I searched google and its a pretty common problem with no concrete solution, might need to flash the rom again.

Why don't you try binding the MAC Address to a static IP so it's no longer able to create multiple entries on the DHCP Table?

tjturko13 - have you tested to use another standard 802.11 Modus - instead "n"? Just switch it at your phone or router.
What router do you have? Can you update the firmware? ^^

i dont think my router allows this, the only option I have is to specify if I want to allow mac filtering.

Have checked out my last post about the wlan-standard?
I found also another thread about a member with wifi problems after updating his rom. He didnt flash the new boot.img - but dont know if it was the solution.

thanks ill check out that thread,
at the moment my router is set to just g
its a isp provided cablel router that does not let me mess around with FW but i have checked and it seems to have the latest FW

where do i get the boot.img file from?

Did you get your new rom over the air? (Stock rom)
Or did you flash a custom rom?
You have to give us more software informations about your rom. Is your device s-on or s-off?
Stock rom you need the right RUU exe file. Just doubleclick - yes yes yes
Custom rom you need to download the custom boot.img.

There is an update available. I saw another post of an user with wifi-problems. He flashed the update and the problems were solved.
I've also noticed, that the wifi might have some problems with some channels as you can see here:
Broken:
bluetooth - works in beta 7. Broken in beta 8 +
Working:
Wifi Tethering
camera - not perfect still buggy
Mic
accelerometer
audio
bluetooth
wifi - may not support some channels

I'm sorry for you.
- You could even try to change the wifi-channel to 1, 4 or 6 and disable wifi-security in the second attempt for test only.
- Try also to set a static ip in your phone (for your wlan).
- If you are bored you can reset the whole router to its factory defaults and leave all standard. Just enable wlan (and the isp connection) - but dont change the default ssid, wlan-security or channel etc.
Otherwise I have no more ideas.
With google you can find dozens of users crashing their routers with android or ios phones . Good luck dude!

Ive had this problem to since switching to 'randomblame's kernel based ROMS (jellytime CM, jellytime aokp and jellytime by PACMAN - Paranoid, CM and AOKP).
Apparently it is a kernel issue and the only thing you can do is some of the things above or here
I was here hoping there might be a fix... I tried static IP, changing the router channel, WIFI never sleep etc etc etc.
The only workaround I found so far was to turn off wifi when Im done, it only seems to break when the phone is inactive for 5 minutes +.

Exact same problem here. It took some time before I figured out that my phone was overwriting my gateway's MAC address, but I finally saw that message from another machine in my network:
Code:
arp info overwritten for 192.168.1.254 by 91:31:58:5d:e8:34
1.254 being my gateway's IP. I also tried giving my phone a static DHCP entry but it just didn't change anything. Any useful sysctl maybe ?

FWIW, it seems I "fixed" that issue by making my routers MAC address association permanent on my (manageable) switch. That obviously don't fix the real problem, but does not shut down the router's NIC. FYI, on a GNU/Linux machine, this is done with the arp command, i.e.:
Code:
# arp -s 192.168.1.254 00:ca:fe:ba:be:00
192.168.1.254 being your router's IP

I dont know if Im absolutely right, but I use a USB 3G dongle, and when I had set it up, there was a note there which told me that if I chose WEP security, wifi devices with 802.11 frequency (Such as our phone and others) wont be able to connect.
So its more like the encryption issue rather than software issue. You can still check it out. Im just sayin as a dev.

For the meantime, if you have a computer at your office, you can use USB Tethering to use internet on your phone.

Annoying wi-fi problem

Everytime i turn on the wi-fi the phone get stucked for like 4 seconds and then the settings app gets crushed.... After its on everything is ok but its annoying to suffer this everytime i just want to turn on the wi-fi.
Tried to clear cache of the settings app but it wont help, anyway to reset that specific wifi settings? Im trying to avoid factory reset so please help me to find a solution other than that.
Btw its lolipop G3 D855.

Check your Wifi configuration files.
You can find the file that usually lead to issues here:
/data/misc/wifi/wpa_supplicants.conf
For example I found a duplicated section that lead to wifi inconsistencies (not working without rebooting the phone).
Unfortunately repair such file requires root.
If this not works you can have maybe the wifi chip broken.

First of all, thanks for replying.
I looked into this file but I don't know find the problem in it...
When I open it I just see some settings like ctrl_interface= driver_param= and such...
I also see saved wi-fi networks and thier passwords.
So what should I look for exactly? i have root so it's not a problem to repair it incase there is a problem in the file.

You can find duplicate sections like the following:
network={
ssid="AN_SSID"
...
}
...
network={
ssid="AN_SSID"
...
}
this kind of duplication confuses the wifi SW.
In my G3 I had to reboot each time to modify something in wifi configuration
I'm also checking if having 2 section "cred" is correct:
cred={
imsi="Auto"
domain="first.domain"
eap=AKA
}
cred={
imsi="Auto"
domain="another.domain"
}
when I removed duplicated networks and all cred sections my wifi returned to work correctly.
Anyway if you haven't such kind of problems you can also have an hardware problem on the wifi chip.

WiFi broked

Hello guys, a year ago I tried root my phone and got bricked. After 2 weeks I finally fixed and came back to the stock rom. Since that day my WiFi is not connecting.
I'm able to search and find any network, but when insert the password, the phone try to connect, the signal go down, the message "connecting" appear, and after that appear as "saved" but not connected. I already tried to define a static IP address, but didn't work.
Can I broke the wifi firmware when tried to root for the first time?
Someone have an idea on what is going on?

Follow the unbrick guide method 2. Make sure you follow it right.. Don't skip any parts because it doesn't work. Don't see how you bricked the phone by flashing SuperSU but okay..

Hmm, if that and the unbrick isn't working then you might want to ask yourself it something is broken. Does it connect to other networks?

No I ve used several different hotspots to connect. The strange thing is that mobile data are working.

hmmm take a look at this thread:
https://forum.xda-developers.com/oneplus-3/how-to/radio-modem-collection-flashable-zips-t3468628
If that doesn't work try to flash ex kernel if i remember it correctly it changes something with wifi to.
If that doesn't work then It's broken or you can fix it by doing something else but dont know what, Good luck
