The wireless connection I had setup was working absolutely fine earlier.
I then plugged it to another router to configure via a network cable and whilst it allowed me to access the router details, I wasn't able to browse the Internet. My understanding is whilst I have another device connected via cable, it is given preference over the wireless network.
I then unplugged the router and expected to have the wireless connection up and running again. Nada. Zilch. I restart the device and still no luck. I deleted the wireless connection details via network manager and restarted hoping to clear any details.
Once it restarted, I re-configured the wireless settings and still nothing. I can connect to the wireless network via other PCs. The only message I get is unable to connect. The connection details are correct. I am running a Debian derivative of Linux i.e. Linux Mint version 12. What am I doing wrong?
Good news. I am back online. The problem seems to be the router I was configuring which also supports wireless connectivity and it has the same SSID as the router currently plugged into the modem. I simply disconnected the router I was configuring and voilà.
Question: Why are all the other computers working fine and the only device that had an issue was my laptop?
