I've been having problems with my wireless. I moved to a new apartment, and the wireless seems incredibly unreliable. Sometimes it will be stable for hours until, all of a sudden, it starts cutting in and out. I'll get 30-90 seconds of normal behavior, then 5-30 seconds of nothing, then repeat. Sometimes the connection will stop working entirely, until I power-cycle the router.
It is extremely, extremely annoying. Surfing the web isn't too bad, assuming you can stand the random 5-30 second waits. But some connections are sensitive enough to timeout, and it certainly makes multiplayer games unplayable.
Facts:
I confirmed the problem using ping google.com -t. I get normal traffic, interspersed with bursts of "Request timed out.".
I've never had this problem before with this laptop.
I didn't bring my own router or modem to the apartment. I'm using what the old tenant had.
Hooking directly to the modem via an ethernet cable results in a stable connection.
Temporarily cutting power to the router sometimes fixes the problem. Sometimes it doesn't.
I reset the router, but the problem remained.
Apparently the previous tenant had issues with the internet, but I don't know what they were specifically.
The router is a D-Link DIR-615, and their tech support is useless.
