This is an extremely odd problem that takes a little clarity to even describe...I'll try my best:
OK, I have a new notebook with an internal PCI Ralink RT2500 wireless card (RT2560F chip w/184.108.40.206 driver) which is accessing my home network and the broadband modem through a Zyxel P-330W wireless router. Everything works normally and I can access the Internet and perform various functions simultaneously or individually. Signal strength and S/N are excellent. At some totally unpredictable point, I lose the ability to make new connections to the Internet until I reboot...but the wireless connection to the router is fine and any _ongoing_ links to the Internet continue OK.
That's the crazy part -- I can be downloading streaming audio, for example, and it will continue indefinitely, but I cannot newly access websites with the browser or connect to the mail servers or anything else. If I stop the streaming audio, I can't reconnect. I've lost the ability to negotiate new connections with the Internet until I reboot. I can access the router menu OK, just not the Internet.
Any thoughts on this? I seem to have read complaints about this behavior with this card, but I am not sure it's the same problem. I have updated the drivers without any improvement.
As always, thanks for any help!
