Mint 13 Mate 32-bit Wireless Problem rtl8192cu [SOLVED]

Postby HAMOS on Wed Mar 27, 2013 12:26 pm

I did a fresh install from Linux Mint 11 32-bit which the wireless driver rtl8192CU for the Edimax Mini USB wireless driver worked prefectly. To Linux Mint 13 32-bit and the same driver ~rtl8192CU~ installed and not the wireless randomly disconnects and won't reconnect until I reboot the computr and sometimes it won't conect on boot. Nothing it the network has changed, only that I did a fresh install of Mint. I read through the forums but could't find an answer to my question. Linux Mint 13 recognized the Edimax while installing and installed the driver for it. I don't know if that makes a difference.


Please someone help me with this problem.

However, in the mean time I'm going to try another reinstallation. This time without the wireless adapter connected, that way I can install the driver myself and not the auto run program.

Did a reinstall of Mint 13 Mate with wireless adapter disconnected. Rebooted, installed wireless driver using Moopi's method here: http://ubuntuforums.org/showthread.php?t=1744371&page=3 with wireless adapter connected. Then I had to follow up with "owh" method on this page: viewtopic.php?f=53&p=684316 before everything worked and was stable.


Do you have to do a reinstall of your system for this fix to work? Idk that for a fact, however, since I backed all my data up and I just installed Mint 13 Mate. I thought I'd let my system be the Guinea pig for the testing of the rtl8192cu driver.


Note #1: Some Upgrades (not updates) may change your kernel and firmware driver settings. I like to install all packages, which when upgrading can only be done through a seperate program or the terminal (Please someone correct me if I am wrong). In doing so it disabled the wirless driver or deleted it. I just ran "Moopi's" method to install the drive again and it worked right off. Rebooted to make sure the changes stuck and so far so good.


Note #2: Still can't fetch all the translation updates no matter what I do. I've tried:
Code: Select all
sudo dpkg --configure -a

and
Code: Select all
sudo aptitude update -o Debug::Acquire::Http=true

and even this
Code: Select all
sudo rm /var/lib/apt/lists/* -vf


Still no luck, any ideas? Not that this has any noticable impact on the fuctionallity of the computer at present time.


So after extensive testing done this morning and following up afterward with:

Code: Select all
sudo aptitude update && sudo aptitude upgrade


Code: Select all
sudo aptitude autoclean


Code: Select all
sudo aptitude remove


As a final system sweep and cleanup I determine my wireless problem to as of now be solved.
