Dell Mini 10v
1 gig ram
The standard network card (not the n one)
Snow Leopard 10.6.2
Newest NBI (0.8.3 released on Dec 25th)
Airport software is up to date.
I was having no issues until yesterday after installing virtual box with xp, textmate, and istat. Now I am having similiar issues to http://www.mydellmini.com/forum/showthread.php?t=16487. Every so often my wifi will stop working but airport will show full bars at the top. The only way to get it to start working is for me to turn airport on and off again and then it will work temporarily and I will just have to repeat the process every time it breaks. I am having this issue on more than one network so I don't believe it is my router.
Any advice? this is driving me nuts.
