My wifi network vanished after updating to CM7 - Defy Q&A, Help & Troubleshooting

Hello!
I've just installed CM7 in my Defy. It's working very well, except that my home wifi network is not appearing in the available networks list!
This happened too with a friend of mine that come to my place some weeks ago, with a Sony/LG dunno-the-model also running ICS under CM. But I didn't look into the problem as I he would only be staying a couple of days.
Now I noticed the exact same thing happened to me. And my network was working perfectly with the stock 2.2.1.
Anyone have any idea of what's happening? lol

In the wifi settings, is there an "avoid poor connections" option? Donno for sure because haven't used CM7, but in CM10 is like that.

No =(
There's only something related to wifi sleep policy, MAC and fixed IP.

Looks like the problem is related to Wifi Channels (CM doesn't search after channel 11), as I've seen in CM forums.
I'll test it by the night and I'll post here if it works.

[Q] Hidden SSID over wifi - cm7 - HTC Aria - no connection

Hi guys well i own a HTC Aria and it is rooted. First I installed Cyanogen Mod 7 on it which is great but the one thing that i have not gotten to work is to connect to a hidden SSID over wifi. I installed as many nightly builds I could hoping that with each new one maybe it would be fixed but sadly no. I am presently running cyanogen mod 6.1.1 of which the hidden SSID wifi works great. Can anyone tell me if this problem has been fixed or can anyone give a solution which does not include making my SSID visable because I can't for personal reasons. Your response is most appreciated.
Sorry, but for the 100th time, your out of luck when it comes to connecting to hidden APs if your running CM.
Ok cool its no big problem, I guest I have to wait for the final cm7 release

No. Not going to happen most likely as mentioned 200 times. Just unhide your network.
That would be impossible as my school uses a hidden network. Can't just waltz up to them and request them to unhide it.
I feel you man i guess for now do what i did go back to cm 6.1.1, it works great with hidden SSID over wifi
The question is why hidden SSID are a no go for CM7?
I wonder if it took this long for cm6 to get the hidden SSID over wifi to work or if it ever even had this problem from the start/to begin with.

Same situation here, I just reverted back to FR008 with HK kernel (for great battery life) and will stick with it until the semester is done or someone manages it to get it working on CM7.
You got it man its just a waiting game but in the end those guy do a great job getting the roms fully working and stable. 5 stars!!!!!!!!!

WiFi Issue

Flashed 3-669-SuperScaryStable on top of nightly cm7 212. Subsequently, WiFi could not maintain a lock. The phone would find the wifi network get a lock for a moment and immediately lose the lock. Get a lock, lose the lock. . . . Settings I tried were Scary and smartass governors 245mhz - 1.2ghz
Anyway, flashed nightly 220 (back to regular cm7 kernel)-- back to wifi working fine.
Maybe I looked too quickly but all I saw in the development thread pertained to Super Scary not working with sense roms.
Hmmmm.

Download wifi analyzer from market and figure out what is conflicting with your wireless router.
toastcfh's stock kernel is considered the most stable kernel because it's been tested and proven to work with everything time and time again.
However, I have no problems with wifi on Scary's kernel. Again, I'm not saying there are no issues because when I'm at work I do have issues but I have wifi issues on my laptop with the wifi here as well, they have way too many APs broadcasting on the same channel (4-5 APs for channel 3, 4-5 APs for channel 7, 4-5 APs for channel 11) so I seriously doubt it's a problem with the kernel but more a problem with your local wifi router configuration.
Run wifi analyzer and it will answer this question.
Am I right to assume that I should run the test you recommend after flashing Scary and recreating the problem - cause on Toastcfh's kernel there is no problem connecting to that router whatsoever?

You can run the same test on toast's kernel.
Well, you know, maybe it's just all about the goofy phone itself after all.
Trying to do the test (following a reboot) I'm just about sitting on top of the router (that I've confirmed is working) with wifi enabled on the shift and all I'm getting is "not in range." Can't get the wifi icon to even display at the moment.
Thanks for the help.

Did it. But seems that I've got the same problem. Connects for a little bit and then disconnects. It just can't maintain the wifi link. Doesn't stay up long enough to even get a screen shot of wifi analyzer.
Maybe I should try another nightly, stable cm7 or sense?

You can't take screenshots on wifi analyzer. Just analyze it yourself. How many APs are broadcasting on the same channel as you? More than 1? Change the channel.
There are two and they don't overlap. One is centered over channel 6, the other (weaker one) centered over channel 11. But the problem is that the parabolas that show the signal strength disappear pretty quickly and the wifi indicator at the top of the phone just disappears. What do you think about the possibility that I should switch to a different nightly or sense?

Ignore the APs disappearing. It sounds like your router is either a piece of junk or misconfigured.
Try configuring the wireless radio on channel 1.
Shouldn't be a piece of junk. wasn't that cheap ;-)
Works fine with my computer anyway.

That means nothing.
What kind of router is it? Manufacturer / Model number?
Also please remove ScaryKernel from the title of this thread since we have proven this problem happens on toastcfh's kernel as well.

Netgear sucks. Do yourself a favor and go buy a Linksys WRT610N or one of the new models.
Other than that all I can tell you is switch your wireless channel.
It's not a problem with the phone or the kernel, it's the router.

Ok - I'll try switching the channel first ;-)
Also - going to find some other routers to test the phone against
Thanks for all the time spent troubleshooting here
Ok - Vic - here's the end of the story, since you've been good enough to work with me on this - -
Installed and ran an app called "FXR WiFi fix and rescue" from the market. Didn't appear to help.
So, restored nandroid of Mik 1.6 and WIFI WORKS PERFECTLY once again. Strong, stable, consistent lock on the Netgear signal (and another close-by router as well.) Problem solved for me.
Not going to make any rash accusations about what the culprit may be which caused wifi to fail for me on cm7.
I'm happy I've confirmed it's not the phone.
Maybe my shift just likes MikRoms and Supreme Sense and was punishing me for experimenting!!

Glad to hear it but I'm still wondering.. did you even TRY changing the channel?
I get 20+Mbps over Wifi on 2.4ghz.
I was planning to try changing the channel, but you know what -- just happened to restore Mik 1.6 first.
And the result was dramatic. On the nightly CM7 the graphs displayed on wifi analyzer weren't stable at all. Even when the parabola's appeared for a few moments, their height was shifting up and down. It was like the signal strength was fluctuating.
On Mik's rom the height of the parabolas is higher than I saw before and just stays put.

Did you do a wipe data/factory reset when flashing CM7? Did you wipe dalvik? Did you wipe cache? Did you wipe battery stats? Did you flash the latest CM7 nightly and then right after that did you flash google apps 828 and new talk?
Not wiping properly before flashing a new rom could cause weird issues like that.

[Q] WiFi issues on almost all ROMs - MB525 red lens

Hi All,
Since I got my DEFY I have WiFi problems. This issue only exists when WiFI has WPA/WPA2 PSK authorisation.
It is going like this: I connect over the wifi. Then connection works fine, I am able to browse www, check the emails etc, and after few seconds, minutes the connection stops working but still exist. I try to reconnect several times. Defy shows that is connected but nothing works fine. Internet apps or Market gives a message like the time is up, connection lost. I have to forget the conection in settings or reset device to get it working properly, but not for long.
And the thing is that there is only ONE ROM that works fine with WiFi on my DEFY. This is Cyanogenmod-7.1.0-RC1. Other ROMs have same issues. Doesn't mater if it is Cyanogen mod 7.1 stable or any MIUI or MS2Ginger. I tried almost all roms but nothing helped. So I had to go back to CM7.1.0-RC1.
Do you know what should I do to make WiFi working fine on other roms?
greetings,
Gregory
p.s.
Please, just don't tell me that I should change authorisation on WiFi router. This is not a solution for me, because I use WiFi in a lot different places.
Same problem
Hi,
I have the same problem with my Defy since a few months, no solutions!
I have the *EXACT* same issue. Was about to roll back to stock and send it in for repair, glad I found your post! I'll install the ROM you suggested and keep hoping this gets fixed
just fixed my wifi issue for the second time. If there are to many remembered networks no more wifi. You can turn it on but it cant find any. delete all remembered networks and back on line. that is the only conectivity problem I have ever had after months of cm7

I think that's a different problem than we're having. It is finding the network just fine (and connecting) in our case. It's just that internet connectivity refuses to work after a few minutes, forcing us to disconnect-reconnect to get it working again
@OP: Thanks a lot! The ROM you mentioned does indeed not have this problem. It's not as stable as some of the more recent roms though, think I'll still be forced to revert to stock
i had exactly that problem with my first defy, no solution man, i send it to warranty and they give me other
maybe changing the regulatory domain channels from 11 to 14 could help. this option is hidden by default, you have to enable it: change the value of 'ro.debuggable' from 0 to 1 in /system/bootmenu/config/default.prop, save and reboot. after that, the regulatory domain setting will be shown in settings/wireless/wifi/advanced. simply change it to 14 channels.

I'm looking into rolling back to a stock Froyo rom but the information is scattered all over the place, I'm having a hard time figuring out if it's possible, and if so, how ;/

OK, maybe I just passed the signpost but... do you still have the problem if you set your "select network" setting to 3G only?
I ask because (and it may be different on my phone as I am USA, stock ROM with wifi calling) if you go into the INFO menu > phone information > set preferred network type, mine toggles between three radio preferences: "GSM only" (when wifi is active), "GSM auto (prl)" and -- if I set for 3G Only, "WCDMA only".
I have noticed that when "select network" setting is at automatic (or 2G only) it often has trouble transitioning from cell to wifi. And, when wifi is an issue, I find that "GSM auto (prl)" has been selected (which on my USA phone prevents wifi connection). However, it seems to have no issue whatsoever transitioning from "WCDMA only" (3G only) to "GSM only", which on my phone then allows wifi connection. Again, this is a wifi calling phone so may be different.
Yep, same here BUT ! I get root browser, found my build.prop and change wifi chanells first time for 14 and it didnt help so i try other and my wifi works in 100% with 13 chanells. Try it
This is a widely know problem, many people are affected more or less. I'm also having nerve-blowing times with wifi sucking all over... Stock Froyo (and now Cyanogen 7.2) seems to be a bit more stable, sometimes everything is fine for a few hours, all downloads go lightning fast - and then suddenly things are screwed up. I tried a lot of MIUI releases as I like it most. MIUI seemed the most problematic so far. I don't know what is the cause, new stock Motorola Gingerbread ROM versions also have this issue (except one I think - look it up in the forum).
Agree, bothering with the router is not a solution. My Nokia E51, my EeePC, my girlfriend's Omnia and Lifebook - all work perfectly with all the four routers we use frequently. Not a single glitch - everything is stable and nice, except Defy.
I don't think is a hardware problem with certain devices, it seems more to do with the way Defy handles wireless connections.
Anyway, it's frustrating but CM7.2 and CEE Froyo gives a bit better experience than others.

CM10 26 Sept Build - connectivity issues

Cant post in the developers forum (not enough posts yet).
Currently running CM10 on a defy green lens but an having issues with the wifi connectivity. When the wifi toggle is on it seems to kill 3g and wifi does not work. turn off wifi and 3g is fine.
Happy to roll back to the most stable cm10 version just no idea which to go with (had 12/8/12 build before that didnt have the issue until this morning for some reason - hence the upgrade)
cheers

Killing 3g while Wi-Fi is on is normal. You cannot use both connections at a time.
Can other devices access the internet using the same access point? Have you properly configured the access point on your defy?

yes other devices can use the web. normally when the wifi is in range it kicks in and overrides the 3g. in this case the wifi symbol was coming on in the botification bar but was staying gray and then not connecting to the web.
As it turns out it all started working again this afternoon - no idea why but after 12 hours of not working it appears to be fine again, and I have updated to the 26/9 build and that is fine also, so I've no idea whats going on here - all i care is that its working again thank goodness,

I'm not having that issue with the play store, however, apps aren't downloading on WiFi or LTE. I just get the downloading message with an endless blue downloading bar... I'm on PureNexus with elimentalX kernel. Any problems like that?
No such issue here, all loads fast on my wifi
Yey, my phone is not " wrong"
Not the same problem but it is similar:
My 6p's wifi would randomly just stop working (no data activity) and then disconnect from wifi and reconnect.
I had it connected to an E3000 router with a recent dd-wrt build (from 2015)... anyway I flashed a 2014 build (kong 22000) and it has not done it again.
So maybe check router settings... WMM etc or reset settings and start again.
flashed it about 15 times all four stock images, cm13 and elementalx kernel
IDK wtf is going on, and this is the second 6P to do this. i did an RMA

I have no such issues.
All three of my networks

thats why im posting because it has no apparent reason
Works fine here. https://youtu.be/3DvU4fXjdNI
Wifi is fine here.
Also, The Wifi Test sounds like a great dance move
Could be your dns servers. Or network settings,
I had similar issues with both the play store and with downloading general files from chrome. Once I updated the play store to v6.0 it happened less frequently there, and once I used the WiFi analyzer app and realized how many of my neighbors were using channel 6 I switched mine to channel 11 and haven't had a single issue since.
nope, doesn't happen with me. I do have very slow lte tho lol
