wi-fi stopped working

Hi. The Wi-fi on my G1 has stopped working.
I rooted my phone with the RC9 uk version by JF. I had no problems connecting to encrypted network.
I tried moving apps onto sd card and ran into problems so I wiped my phone and reset everything.
I cannot connect anymore on open or encrypted network. I can view it and when I try and connect it, it try's to obtain ip address and then fails!!?
Any ideas? Thanks

Hi
Does anyone think it's worth flashing back to the original version? I suspect not because it worked ok on the jf version I have but don't know what else to try?
I will try another wireless network at work today.
If my phone is picking up the network but not connect sound like a hardware problem or just a software one do you think?
Thanks

I had a similar problem but it was a router issue. I would def try another router before blaming the phone.

Ok. I just tried another router at work with an open network and its still the same. Shall I flash the phone do you think. Don't really want to do it again but I use the wifi network a lot and I am worried it could be hardware.
Thanks

well if you flash it and still have the problem then its hardware based. So nothing can hurt from flashing

I re flashed with latest version rc9 jf version and now working again. Thank you neoob

Fixed my wifi

Netgear router at home and I couldn't connect to it, but my Girlfriend's stock magic could. I noticed this issue with dwang 1.6 and then cyanogen 404 and 6. Countless factory resets and wipes on my phone. Flashed new radio for the 15mb update yesterday and still no luck*
I was able to connect to other wifi so it was really annoying.
Sorted by updating my router this morning. Happy.
*Don't recovery flash a S-on SPL. Silly Sam.

Spoke too soon
My router hates my phone and is picking on it. Sigh.
Any ideas what to check would be welcomed. If I reboot the router I get wifi briefly then I cannot reconnect. Router logs don't show me trying to connect.

Sorry to necro this but I thougth I should share that reinstalling windows has fixed this. My own PC was bumping my phone off the network somehow. IP conflict I assume. So nooby of me.

Wifi problems/ CM7

Hey All!
Having problems connecting to the university's wifi
there are a few networks, some secure (802.1x and enterprise wpa(?)), one is open
At times, even when in areas of strong signal, the phone wouldn't connect
to any of the networks, or it would start to connect and then fall out
and start looking for other networks, even when there are other, it would usually not connect to any of them and continue wasting my time
if I have a 3G data plan, i wouldn't even bother, but unfortunately, I don't...
how do I fix this?

your having problems connecting to the secured ones ?
ive had the same problems , heres the thing :
my guess is ur uni has numerous routers with same ID , ur phone pairs some info to that ID , and if u wanna connect to another router with the same ID , it wont work.
heres what to try :
next time ur having the same problem with "good signal - no connect" , just detete(forget) ur unis wifi profile , re-scan re-enter ur id/pw , and it should work .... till u try yet another router , its a pain ...

Tried it, numerous times...
didn't change a thing...

Kernel?
What ROM are you using with what kernel? Highly probable this is a kernel problem. Tytung r6 for instance does not have this problem. This kernel is delivered in for instance the TyphooN Rom on TyphooN CyanogenMod 7.
v2.4.1: Updated to tytung r6 kernel. This fixes IEEE 802.1x/EAP authentication support as well as native tethering.

Click to collapse

I'm using
2.6.32.15-g0e4b5ff-dirty

That's the problem. Either flash to another ROM or find out how to flash another kernel.

forgot to mention,
My device isn't flashed,
I'm surring CM7 from the SD Card

A solution
I find A solution (not THE solution) : reinstall the ROM and it's work find until the next time...
the reinstall doesn't RAZ anything, so it's 2 mn time

The last comment is not clear!
Wifi peap aslo does not work for my university. I tried many ROMs
Only darkstone from SD card worked long time ago, now I am running android from nand

Same problem here ^^,
Will try to install some kernel

5GHz Wireless N?

I had my phone connecting to my SSID-disabled 5GHz wireless network for several weeks--even while rooted--and then after flashing my ROM, haven't been able to reconnect no matter what (turned on SSID, no security, etc.). It doesn't seem to matter what ROM or kernel I use, either; I'm currently on Virtuous Doubleshot 1.1.6 but I also couldn't connect using Generation-X GB Stock V4. In fact, it doesn't even see my network. I haven't touched the radio at all.
I really don't want to go back to stock; does anyone have any ideas what's going on?

I think you need to upgrade your radio and try.
If you are on 2.3.4 based rom use the radio 2.19.531.1 RUU
Refer this post it gives you all the available radios & the procedure.

Radio shouldn't have anything to do with wireless drivers, AFAIK.

Wifi Bug

Can someone help me.
I have a Bug at my phone, that after connect with more than 2 or 3 Wifi networks my wlan doesn't work anymore.
I can start it and can try to connect with a network but then it tries to get an ip address and it lose connection and reconnect.
Everytime i get this i have to re flash my phone to get it work again.
Does someone know how to fix it?
I'm currently at CM9 FXP 215 with Lupus Kernel V8-720P
But it doesn't matter what Kernel or Custom Rom i have flashed

Ok now i have a way to fix it temporary.
I set a static ip for all Networks(same IP at all networks, because they are all from me)
