can't connect to network since migration to Mint 14

Postby pennywhistle on Mon Apr 22, 2013 7:17 am

This is actually a question involving ethernet and wireless, but I thought best to put it all in one place.

I recently moved from Mint 10 to Mint 14 and am having no success at all in connecting to the network. Initially I was trying to connect with a cable but that wouldn't work so thinking there might be a problem with the cable itself or ethernet card I plugged in a nano wireless dongle - both were working on my windows partition, although interestingly the windows now also tells me the cable is unplugged althought it's not.

When I try to connect wirelessly I get the problem where it's continually asking for the password and never connecting. I tried installing the driver from Realtek's website, but get a message which tells me the command isn't recognised, so tried installing the windows driver sometimes this works (I've also tried reinstalling Mint several times), but I still can't connect and sometimes I get a message saying that ndiswrapper isn't installed. I found a post suggesting installing wicd might work, but I wanted to make sure this was the right solution to try before messing with network manager.

Here's the output from various commands:

Not sure what super-user means, but happy to run it again if someone can advise. I don't mind connecting either wirelessly or with the cable, but both would be nice. As you can tell I'm not technically minded, so I do need answers in plain English but have managed to solve a number of problems since I started using Linux a few years ago, so I'm willing to give things a try, and really want to be back on my Linux desktop - having to work in nasty old windows just now.

Many thanks
Penny
