Hello, Ive installed Ubuntu recently but none of my attempts to get the wifi network working were successfull. It establishes connection but the indicator shows no signal and I cant connect to any website, I tried pinging external IPs etc. None of these worked.

lspci -nn | grep 'Wireless Brand'Does not show anything.

I could find 03:00:0 Network Controller: Intel Corporation Ultimate N WiFi Link 5300

lsmod | grep "wlan_module_name"Doesnt show anything.

Restarting network says only:

The network Im trying to connect to is hidden, so I have to input SSID manually, I doubt this causes the problem.

This part suggests your card is trying to join an ad-hoc network, that is, computer to computer, instead of an infrastucture, that is, computer to router:
wlan0: Creating new IBSS network, BSSID fa:c0:f9:1c:25:cfIs the behavior improved if you do in a terminal:
sudo iwconfig wlan0 mode managed

Thanks, Ive already solved the problem by looking up the debian forums as my friend adviced. However, this is my second computer I install ubuntu to and I had network problems with both of them :(

Edit: adding a link if anyone has the same problem with these intel wifis
