Anyone have issues with slow internet after upgrading to Mint 12 and Ubuntu??
This reply may be late, but better late than never.
Slow internet and download speeds? Maybe try this.
I was Running Mint 14 and the internet has been desperately slow(!). I disabled Java and pictures and pages were taking minutes to upload. (Not kidding) I searched a lot online only to find that the answers were focusing on this or that, but the problem wasn't getting fixed. (Except someone said that it stopped when they changed the router).
I almost gave up and installed Windows. I wouldn't give up easy, but if you look online you'll find complaints about this in Ubuntu and Linux Mint that are very old and many of them. Some people were getting very technical and it wasn't helping them. I tried disabling the IPv6. I tried changing the Firefox setting for attack sites. I tried installing the pnsd (it's still installed). Nothing. I found the driver for this particular Athenos model and installed the .inf file through the Windows Wireless Drivers tool, it installed. Still nothing. The internet was hardly coughing up text.
Then I read on some forum that Athenos is particularly problematic. That's what I have for wifi. Also a recommendation to use the program wicd and that it's better for wifi than the standard Network Manager that comes with Mint. I installed wicd through the Software Manager (it took a while to download) and after toggling the Properties and changing it to WPA1/2 (passphrase) and some refreshing... it worked!!!

I just opened youtube.com and amazingly everything was downloading as normal. Alhamdulillah. Anyways, I signed up here on this forum just in case anyone has the same problem. I'm running an Emachines e527. I hope that this benefits someone who may encounter a similar problem.
