Can you help me to fix a problem with my N900, it will not connect to any WiFi network, and has not connected to 3G properly in a while.

Previously I had Auto-Disconnect and Wifi-Switcher installed. 2 weeks ago, I read here how auto-disconnect was draining battery for some people and thought that I would uninstall it to see if it had any effect for me. I also uninstalled WiFi-Switcher at the same time.

Since then, the N900 has not been connecting to any Wifi. It can detect the networks, I see them under 'Internet Connections'. But when I select one to connect to, the WiFi icon in the system tray flashes a few times, like it normally does when it is connecting... but then "Network Connection Error. Try Again?"

This happens every time, on every wireless.

Possibly related, but the GSM signal in the system tray has only said 2G for the past 2 weeks, and never once has changed to 3G.

I don't know how to diagnose what is broken, and how to fix it. Can anyone help please?

EDIT: Would it be helpful if I installed syslog?
http://wiki.maemo.org/Documentation/.../maemo5/syslog

It says on that page that it's important to remove syslog when you're finished with it, but it doesn't give instructions on how to do that. Can anyone edit that page to include removal instructions, please?

Let see if running the following as root help:

thanks very much. I pasted that into a terminal and started to see some things happen with the network icons and now I have a 3G connection!

Unfortunately it's still refusing to connect to Wi-Fi, gives the same network error message.

(when u say to run it as root - did you mean anything other than just pasting it into a terminal)

You need to gain root privilege otherwise only the last line of the command would work, and that's the one getting your 3G back on.

In order to gain root, you need to install rootsh and then enter the root shell. Install rootsh from application manager, and run the following commands to see if could connect to wifi again:

Thanks... I'm probably getting closer. It told me that iwconfig wasn't found, by any chance should the last line of that code be 'ifconfig..'

specifically, what it said was "-sh: iwconfig: not found"

But it seems to be connecting to the internet now.

My battery levels seem to be dropping like a stone, the CPU has been running like crazy since I executed those commands in the first terminal. (so - more or less since the 3G came back on I guess)

Is this how bad the battery is when I don't have auto-disconnect running?! Holy moly. It's gone from a charge of about 900mAh to about 300mAh in about 4 hours.

Well, anyways, I appreciate your help solving the problem that I started the thread about, I suppose I can always ask elsewhere to try and fix my battery issues.

If the wifi works without having to change the mode to 'managed', then that's okay, unless you happen to use mobile hotspot in the future.

Some processes was restarting when the internet connection comes back, thus the battery drained. It may be normal.

Thanks, this seems to be working fine. The battery is draining quicker than before, but that's for a diferent thread. Thanks for the the help.
