USB WIFI dongle doesn't connect on desktop

Hey there folks! Here's the weird situation I've encountered today:

Got wifi usb dongle installed on desktop with no problems. Found my connection, ok. Trying to connect - password - authorization fails. Removed password in router settings - trying to connect - connection fails.
The irony is that I did the exact same steps on laptop which has the exact same statler, and everything worked like a charm (I switched off laptop's wifi of course smile ) The dongle is Realtek RTL8192CUS. Any takes on the matter?

Re: USB WIFI dongle doesn't connect on desktop

Realtek, how I loathe thee at times. Do both computers have the same kernel installed, and have you had to install any specific Realtek drivers? (I ask because I've had to do this before, but that was mostly on older kernel versions, honestly.)


I luse superbly, with style and aplomb.

Re: USB WIFI dongle doesn't connect on desktop

It wont be the right answer, but hey, I just love saying this:

sudo rfkill unblock all

You probably know more about it than me.

Try:

uname -r

on both systems to see if they have the same kernel

Yep, both systems are completely identical incl. kernel 2.6. And yes, I had to install a driver from realtek. The only difference, that it was successful only on laptop.

Re: USB WIFI dongle doesn't connect on desktop

Post output of

uname -r
lsusb
lspci|grep -EiA3 net
dmesg|grep -Ei 'net|wlan|firm'

with  the dongle inserted, on the desktop.

Do the same on the laptop and compare outputs.

Re: USB WIFI dongle doesn't connect on desktop

02:00.0 Network controller: Intel Corporation Centrino Wireless-N 1000

Your laptop is using the Intel wireless card.
The Realtek is not working on either system.

I guess you will have  to upgrade to the latest kernel in backports to get the realtek working.

Nope, it works perfectly on laptop. I didn't turn it off while making requested output, but during the dongle test I did turn it off (I wrote it in my first post)

Re: USB WIFI dongle doesn't connect on desktop

Ok, the problem is solved. The dongle works only on 13th channel, and I simply missed it smile
Thanks everyone.
