My sister bought my niece a Gateway T2330 and a D-Link Wireless-N Router, both from BestBuy. All worked well for the first several days but after that all has gone downhill, as the wireless will no longer connect to the internet. It will only establish a "local" connection (connects to the router, but not to the internet through the router). Here is what I have done to try and resolve the problem thus far...
-- Restart the modem and router - I have found that neither of these are the culprit as I am able to get my MacBook to connect to the wireless network when the Gateway will not.
-- Enable the wireless card - At first the problem was that the wireless card was not enabled in the Device Manager, but I have since turned it on with the button on the keyboard and under the Device Manager.
-- Try and connect through ethernet - Even though the Gateway will not connect wirelessly, it will connect through Ethernet and stays connected with no problems.
--Try connecting to other wireless routers - The Gateway will not connect to my AirPort Extreme either.
-- Update the drivers/software - After connecting through the ethernet, I downloaded a new driver for the wireless card through software update and SP1. This fixed the problem for about 2 days but it has since stopped functioning again.
I really am at a loss as to how to fix the problem. Any suggestions would be helpful, I don't have the computer at the moment but when my sister stops by this afternoon I will have her drop it off.
Neither wireless router has any sort of security enabled by the way.
