The last week or so I've developed a problem maintaining my wireless network connection.
I'm running Windows XP on a laptop. I have an external wireless N connector, along with the built in b/g connection.
At the start of the day, I connect without any problems. But 2 or 3 hours later, I lose my connection.
My computer shows that the two wireless connections are still enabled and still connected, but I don't have any internet connection.
The problem doesn't appear to be with the DSL modem and wireless router.
If I reboot the computer, without making any changes or reboots at the modem or router, my connections are restored, for another two or three hours at least.
I've updated drivers for the wireless network adapters.
Any other suggestions?
