In other thread someone has reported that the problem solved by reflashing the firmware. In the meanwhile if you don't want to reflash yet, you may try the following commands under xterminal to see if they helps:

Hello, when i enter each command and enter it asks for password, what am i suppose to enter there plz help me thx

Then you must install rootsh then:

Plz when i enter that command It says

E: could not open lock file
E: unable to lock the administration directory

what do i do now plz

Hi!
So I guess you have not worked with Linux systems yet. No problem, but it always helps to at least at the basics understand what you are doing.
Like this you will learn the most and get closer to the full potential of the device.

The system is able to perform different tasks with different rights (like reading and writing certain files, acces to ertain hardware features) for security reasons. These rights can be set per user (not only physical) or groups. The superuser/root has read/write/execute acces to everything on the device. To execute a command as superuser, you can use the "sudo" command. Or you can login as root by typing "root" in a terminal.

The superuser/root account is not active on the device per default. You have to install the package "rootsh" and perform the command "sudo gainroot".

You should consider to take a look at the maemo wiki for beginners.

Btw, I don't know if the commands will solve your wifi problem, as I have no problem with this, and you don't provide useful information to solve that problem.

Installing packages with apt-get requires root rights. Installing the program to provide root rights won't be possible consequently.

Just use the graphical package manager and search for rootsh.

where will i find the graphical package manager

You may want to go through settings -> Internet settings -> connections. and play with it from there.

Ok...download the following file, copy it to your N900, cd to that directory, and run the following command under xterminal:

If it still asks for a password for the above command then we should think of something else, like copying the binary for you directly.

Just feel free to raise any question. I can help you as much as I can as long as I'm around the computer. ^^
