Okay so im having a problem with a computer ive been working with. Recently I had to change the wireless security password on my network. When I did so the network went from being completely stable to giving sparadic internet. I tried messing with the wires. Resetting the modem, router, and computer in turn. Giving them power off time. Released and renewed the ip on the computer. All the settings are set to automatic. Im running windows vista. Ive tried plugging the modem straight into the laptop and it seems to not take the internet through it or a network connection however it connects to the network fine wirelessly. Ive found a slight workaround which I dont know if it will help narrow down the problem. With the router settings page up if I release then renew the ip from the router settings page I get internet for about 2-3 seconds before it drops off again. I prefer not to have to buy a new router and get my isp to give me a new modem. Also When I did reset the network password I had to remove the old saved network settings and disconnected to reconnect with the new password. So maybe the pc was seeing both passwords still like a ghost image of the old one and the new. So I renamed the network to a new name and it was still having the issue. Help please.
