[Q] Network connection issues

Not sure exactly how to start this off but I am having issues using my network on my X10. I've included a screenshot of the general info from my phone. My X10's bootloader is unlocked, CM7 installed. I followed the directions here to unlock the bootloader and get CM7 on my phone. I have the applicable APNs for the NTT Docomo network (also included screenshot). With wifi enabled the mobile network connection becomes disabled and re-enables itself when wifi is turned off.
I've searched all over the forums and the internet and couldn't figure out any fixes. Any help will be appreciated.
Yes, the data problem exists in fxp 41 and 42 of CM7. Ppl have said that icons turn green and then there network dosent work. Thankfully I am not facing it.
I dont use market and havent synced my phone with google account. Hope this works for you.
I've been looking for the FXP030 but the link is down. Is there a mirror or another CM7 mod that I can use. I've tried using busybox to kill servicemanger but busybox is stuck on a loading screen even after rebooting the phone.
CyanogenMod network problem
Hi all i have this problem also...
network not working, and problem with market and email..
ifi go to recovery and wipe dalvik then market works but when i try to go on internet or try to setup email network crashes...
The FXP30 link is down. I guess someone has requested to reupload the files. Check there thread for this update. I guess fxp 43 will be released anytime this week. So try your luck on it.

[Question] MiniCM7-2.1.9 wifi not working

I'm on the latest nAa kernel, using MiniCM7-2.1.9, but wifi just doesn't work. I can browse the internet using my 3G connection, just not wifi for some reason.
Wifi shows it's connected, the signal bars is full but it just doesn't download any data, it's like it's not connected at all. It's able to get an IP address and the link speed is good but it just doesn't get any data.....
I've tried searching through different posts and tried solutions such as:
http://forum.xda-developers.com/showpost.php?p=21766413&postcount=498
as well as the instruction to fix wifi in the Troubleshooting page here:
http://code.google.com/p/minicm/wiki/Troubleshooting
and this:
http://forum.xda-developers.com/showpost.php?p=22170822&postcount=817
I also cleaned the dalvik cache by going into recovery, reboot and still doesn't work.
and they all don't work....
UPDATE:
OK nvm it works now. I reflashed the kernel, wipe data & factory reset and then reflash the rom, and now it works. It's the exact same thing I did for the past 30 mins, except this time I also reflashed the kernel. I just hope it'll continue working.....
UPDATE 2:
Ok, now it's not working again. I rebooted the phone twice, and it was able to connect to wifi no problem. But then later on it stopped working again, I didn't install or change anything either.
I also noticed that whenever I'm connected to wifi on my phone, the wifi on my PC will timeout and drop connection. If I then try to connect wifi on my PC, then the wifi on my phone will timeout. Basically, I can't connect both at the same time.
But all my other devices work fine. My Motorola Milestone and my mom's HTC Desire Z works fine. My iPod Touch works fine, I've NEVER had a wifi issue with any of my devices until I tested out my new Xperia X10 Mini Pro today.......
I haven't tried testing it on stock rom & kernel, because the first thing I did was to unlock the bootloader and flash the nAa kernel + MiniCM7-2.1.9. And I can't be bothered flashing back to stock since I won't be staying on stock anyway, especially after setting up everything already so I can't really be bothered.....
Anyway, so I then tried to delete wpa_supplicant.conf in data/misc/wifi (as mentioned above) and this time it shows "Error" under Wi-Fi settings.
This is really annoying me....
One note about wpa_supplicant.conf (/data/misc/wifi/wpa_supplicant.conf). In stock kernel with MiniCM Pro from paul-xxx the right ctrl_interface was wlan0.
nAa kernel (with MiniCM from nAa) needs tiwlan0.
So it isn't necessery to delete file with all wifi networks when changing kernel/ROM but one value in config file.
ya, except the value was tiwlan0 already, I tried changing it back to wlan0 and nothing happens. So then I tried deleting it, and now whenever I try to turn Wifi on it just shows Error.
What's actually strange about this is that I've backed up the original file, and when I restored it and tried to turn Wifi on, it turns on but doesn't display any network.
Before, it would display tons of networks, and it would connect to my router (but doesn't download data for some reason). It doesn't work but at least you can tell it's able to detect networks.
Now, it doesn't even show any networks. The only way to fix this is to restore from recovery or do a wipe......
Ok so I did some research and could this be the case?

I've also tried to assign static IP but it still doesn't work. I went into my router and checked the ARP, and it shows this:
IP address Flags MAC Address Device
192.168.1.2 Complete 00:18E:48:42:C9 br0
192.168.1.3 Complete 00:E0:4C:A3:8B:A8 br0
192.168.1.6 Incomplete 18:87:96:FE:16:3E br0
192.168.1.5 Complete 48:5D:60:3B:5E:5D br0

where 192.168.1.6 is assigned to my phone. I'm not that good with router stuff but know the basics, does anyone know what I need to configure?
I'm having the same problem with my mini pro

[Q] CM7.2 Wifi issue

Hello everyone,
I just reinstall CM7.2 with wipe of the entire cache, and I can not connect to my wifi network (WPA2-PSK) that is configured with a key as 123456789. My PS3 is connected to the network and everything works. I tried with another phone Samsung Wave II type and again, that works. I tried with my Legend on another network with the same security and I could connect.
Back on my network, I try the connection again, and still nothing ... I changed the security to WEP, my phone could connect.
Could someone explain to me why I can not connect to my wifi WPA/WPA2-PSK?
Edit : I try to switch wifi network to WPA-PSK, it seems to work fine, but why not with WPA2 :s
I found this : http://forum.xda-developers.com/showthread.php?t=1605047 !
I'll try it
With this fix, wifi can't be activated :/
Any idea please ?
Thx
