I'm new to Mint (long time Ubuntu user, previously used Knoppix and Kanotix for a few years).

I'm having two problems:

1) wireless disconnects under high CPU load
2) kernel crash when I disable networking (or sometimes when I disable wireless) from the tray menu.

My system: Linux Mint Mate 13 installed on an old Compaq EVO D310, 1.5Gb RAM with an Airlink 101 Golden N Wireless Mini USB Adapter.

It boots up fine, and most stuff works fine. I've installed Chromium from the Software Manager because Firefox maxes the CPU on normal use of gmail -- Chromium works fine.

When CPU goes high, the bars start to drop on the wireless connection icon. Occasionally that results in the wireless connection dropping. Sometimes it will reconnect by itself. Other times it gives up. So I try disabling wireless networking from the tray icon and then re-enabling it. That sometimes works. On a couple of occasions I tried disabling networking (not just wireless) from the tray icon, and the whole system crashed. (On at least one occasion that has happened when I tried to disable wireless only). I *think* it happens every time when I disable networking.

Crash results in a black console screen with some log statements related to video; keyboard unresponsive. Ctrl-alt-F2 and Ctrl-alt-del do nothing. So I power cycle and it boots back fine. I then go back to the tray icon and reconnect and all is fine. But after awhile it happens again.

Obviously it would be great to fix the crash. But I might also simply be able to avoid the crash if I could get the wireless connection to stay up. Is there any configuration change I can make to cause the wireless subsystem to be more tolerant of the high cpu cycles?

Thanks in advance for any advice.
