Wireless won't connect
From MEPIS Documentation Wiki
During wireless setup, many report having to do this during wireless setup in order to get a wireless connection:
1. While setting up wireless, the KDEWallet a.k.a KWallet system wizard opens up. Select "Basic setup" and then "next"
2. Next window, Click "Yes, I wish to use KDE Wallet...."
Now, If you do not plan on using KWallet for anything else, you may leave the passwords blank, and click "Finish"
If you enter a password, Do not forget it!
NOTE: You always have the option of going back into the KDEWallet setup to change your settings.
3. For the next window, if you used a blank KWallet password, you can choose "Allow Always"
If you used a password you can also choose "Allow Always" OR if you want extra security, you can choose "Allow Once".
4. For the next window, not sure about this one. If you do not plan on using KWallet for anything else, it may be OK to choose "Deny" and see what happens.
Again, You always have the option of going back into the KDEWallet setup to change your settings.
