Recently, I have installed Linux Mint 10 Julia. Everything worked from the beginning (even the external wifi dongle), but I discovered that the wifi connection gets lost after some time. To solve it, I have to disable networking and re-enable it.

Does anybody know what the problem could be? Further details can be found below:

The wifi hardware I am using is this:

lsusb
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 003: ID 07d1:3c09 D-Link System DWA-140 RangeBooster N Adapter(rev.B1) [Ralink RT2870]
Bus 001 Device 002: ID 1221:3234  
Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

UPDATE:

When trying to manually install the driver for the wifi, I got this error while compiling that driver:

This could be because I couldn't update my compiler? While I am connected to the internet (I can access the internet through the browser), the terminal always responds with a 404 not found when trying to apt-get update.

Could you also post the output of inxi -n? You may have to install inxi but it's in the repos and worth having. –  terdon Sep 15 '13 at 3:56
    
Could you try to boot from a current Mint Live CD and check if Wifi is working? "Julia" is based on Ubuntu 10.10 and almost three years old - the problem may already be fixed in recent version. –  tohuwawohu Sep 15 '13 at 7:28

Well the problem is that I want to use it on a very old computer (+- 14y with a processor of 850 MHz), so Linux Mint Julia was the first installation that was somewhat smooth. The other version feel too demanding for the computer. I hope that it is possible to solve this wifi problem in this version of Linux. –  Consec Sep 15 '13 at 10:09
    
@Consec: Did you try the (current) Xfce version of Mint? It dosn't contain a full Gnome desktop, so it has less hardware requirements. I would recommend strongly to use a current distro with security updates instead of an outdated one. –  tohuwawohu Sep 16 '13 at 6:01
