[Q] Flashing to CM7 without breaking wifi? - Galaxy S I9000 Q&A, Help & Troubleshooting

I have a Samsung Galaxy S I9000 Euro which I have been painfully trying to get on to CM7 for the last few days. The problem I have is when I flash back to a stock Froyo (2.2.1) my wifi won't connect to wpa connections. This isn't brilliant for me as my home router is secured with WPA and I do not wish to change it, as the people living in my area are all mostly IT specialists and would take advantage of a wep or unsecured network. This is due to the slow speeds we get in our area.
Does anyone know of a way to flash an older rom on to my phone whilst keeping the ability to connect to wifi properly once it is running CM7?
I am currently running a 2.3.3 rom downloaded from samfirmware.com
Thanks in advance for any help

Why is your WiFi-connection 'broken' with Froyo? My router is also secured with WPA and don't have any problems...

This I cannot figure out, I tried everything from enabling/disabling wifi/GPS/BT and wiping and starting all over again. All of these methods resulted in my phone being unable to connect to my WPA secured wifi, any unsecured connection nearby connects straight away. I seem to get stuck in an obtaining IP address loop, which never resolves.

Have you ever tried another modem?

How do I do that? On 3g its a little difficult to download a different modem as the extras for cyanogenmod won't load properly in the ROM Manager app.

A different modem won't help...wifi is controlled by the kernel, not the modem.

Have you tried connecting to a different AP using wpa?
Also, go into advanced wifi and set up a static IP. That may do the trick.

WiFi has nothing to do with the modem? Ok, didn't know that.

Is this installed via odin after CM7 is installed?

Not Odin. Custom kernels are flashed from recovery as zip files. Very quick and easy.

Tried a few other methods of doing this and every time it gets broken. Are there any other fixes I can use to get wifi to work again? Any files I can modify myself or delete?

Right, managed to convince my other (better?) half to let me try it on her phone as we both got the same phones at the same time. Will post results soon...

Ok, same thing happened with the wifes phone so I decided to dig an old wireless router out of the shed and set it up with WPA security. And the phone then connected. So I'm not entirely happy with the crap that is my BTHomeHub. All in all, I'm now running CM7 RC1 and I'm happy as larry with it

Congratulation!

That is not my network. It is from bars in the city. I reflashed rom. And works fine until I root my phone. because of that i using now stock rom unrooted

I discover that when I root evan stock rom my wifi stop work like when phone is unroot. I only can connect one time on some wifi connection. After when i once came out of range and then again got in range it won't connect. But when phone is.unrooted than everyting is ok.
Some solution?

What's your current rom and kernel? Which kernel did you flash with Odin or CWM?
You could try longpressing the wifi you're connected to and press "Forget", and then reconnect.
I tried all that. I was installed ginger+, also broodrom bussines(sorry if not write correcr) and the same problem. If i using stock rom but only rooted problem still exist. Only if I use stock rom unrooted than works fine.

Not possible, rooting simply tricks the system into mounting r/w so we can pish the such binary/app/busybox. Nothing to do with WiFi ! Did wipe data?
Sent from my GT-I9000 using xda premium
I just said what it is. When I root phone that is what happen. I did full wipe. More times. It is not my first time with rooting and flashing. Before gsp i got x10 mini pro.

[Q] Internet not working after flashin Cyanmobile [20/02/2013]

After flashing the cyanmobile X rom (latest official one) my internet stoped working. No data over mobile network (yeah checked the APNs and all) and no internet over wifi either. It connects to wifi but simply no internet. I did a "ifconfig wlan0" which showed that it had the dhcp ip assigned by my router. The problem is not with the router because other android devices are working just fine.
Any solution to this? please help!!
Thank you!
Change baseband. If this happens after a clean install, baseband is the only possibility I know about.

You have to set correct permissions to these files.
Set it to rw--r--r I guess

Which ones? And are there other roms for the desire c that have already included this fix?
Thanks! :good:
The broken wifi was a major drawback for me, because of the short battery life... I have no developer skills.

WIFI hotspot on CM10 ROM
Folks.. some info to add to the fray..
My WiFi is working, stable and connects every time.
I've also got a working WiFi hot spot (see edit at bottom)
I'm doing this on cute_prince CM10 build 3...
http://forum.xda-developers.com/showthread.php?t=2265060
With the instructions from post 1 of the WiFi fix
http://forum.xda-developers.com/showpost.php?p=49035215&postcount=1
I'm using NOPE v2 kernel 750mhz
http://forum.xda-developers.com/showpost.php?p=42314934&postcount=1
(I had the WiFi connection problems using prometheus CM10 kernels -I don't know enough to know why the difference with NOPE)
To get a WiFi hotspot - (I saw someones post in the desire c forums -cant remember who or what thread, but thanks!) to try the Barnacle WiFi tether app:
(https://play.google.com/store/apps/details?id=net.szym.barnacle&hl=en-GB)
- You need to enable "Skip wpa_supplicant" in its settings. It does mean however that the hot spot is an unsecured network... I confirmed the hot spot to work with my windows PC.. will try with my nexus 7 later.
I've got "Keep WiFi on during sleep" set to "never" as i like to turn it on/off as required. It reconnects every time. If i leave the WiFi on and put the phone to sleep (i.e it`ll disconnect the WiFi whilst asleep), the WiFi will reconnect fine every time i wake it up. No rebooting required.
Hopefully this is a solution to peeps who want a usable WiFi, and for any devs trying to solve this issue..
BTW thanks all devs for cooking some nice ROMs and Kernels to keep this little phone going. A few months ago I was ready to bin the desire c and the stock slow sense!
obs
edit- WiFi hotspot works fine with my win 7 pc- i can see and connect to the hotspot, but on my nexus 7 2013 i can't see the hot spot at all
edit 2 - Looks like the issue with the nexus 7 is that android devices are not able to connect to ad-hoc wifi networks which is what the barnacle app creates!

[Q] 3G problem?

So I have this problem with my Galaxy S Advance... I am connected to my provider's 3g network and in-apps everything works fine but when I enter the browser I don't manage to get connection to the internet. Has anyone had similar sort of problem or anything?

Try with clearing data and cache of Browser from settings/manage apps (or whereever it is, I am not on stock for a long time and I can't remember where it is )
