WLAN on acer aspire one disappears by itself

i dont mean this literally. but sometimes on my aspire one running win7, the wlan just disappears and it looks as though the driver uninstalled itself. the first time this happened i paniced and downloaded another driver. i restarted and it was fine. later on it happened again and i figured id just shut down and boot up again. it works fine after that. but i want to get rid of having to reboot after long periods of time. the lan disappears after a few hours of activity and i still cant pinpoint what triggers it.

im using an acer aspire one a150 with windows 7 7600

Try changing the router's radio channel. 1-11 are possible with US firmware, 1-13 with European firmware. Definitely sounds like an interference problem from neighbors/microwaves/wireless telephones which all could be on or too close to the same frequency (usually ~ 2.4 GHz.)

i usually go online in coffee shops or leech from my neighbor (sue me! haha). and whether its a high signal hotspot or a low one, this problem happens. and when it does the wlan wont turn on using the switch.

the first time it happened i checked the device manager and saw that the wlan driver said "not enough resources to run" bla bla bla

im also wondering if it is in any way related to this other problem ive been experiencing with aero. which turns off by itself as well. it reverts back to win7 basic.

are these hardware problems? by any chance?

and also, the wlan light becomes steady and doesnt blink

here is a screenshot:

Unrelated, but those errors are for your card reader. Try finding a driver install for that if you want it to work again for you.

okay, i tried diagnosing it and after i did, this happeneed:
