Computer won't connect to internet?

Question

Recently our home computer (desktop) stopped connecting to our wireless router. It starts to connect and then as soon as it connects it disconnects and starts trying to connect again. We even got a new adapter to see if that was the problem, but that wasn't it. Any idea's on what I could try?

We're using one of those adapters that go into the usb port so you can connect to wifi, and we have a router that AT&T gave us.

Answer 1

I gather it used to work and stopped working. Do you have any other devices connecting wirelessly that are still working? If not it could be the router not the PC especially since you've swapped out the adapter on the PC side.



Have you tried unplugging the modem and the router while the PC is off. Then turn on the modem and wait a full minute or two. Then turn on the router. Wait a full minute or two. Then boot the PC. Sometimes that clears it.



Can you connect the desktop to the router with a LAN cable rather than wireless to see what happens.

Answer 2

it is possible, if your USB port is wobbled too much, that is has gone flaky on you - that happened to my mom's laptop - that's why there are USB hubs (saves your ports)!



really - the ethernet version of the modem is the best way to go. buy a $15 ethernet cable.

wireless N would be better than wireless G. try the belkin adapters for wireless dongles. and possibly if you can, mount it in the back of the pc in a PCI express card socket.



I know that because of the badly made firmware on most routers, they pretty much all need to be power-cycled once in a while. the only fix for that is dd-wrt (you have to flash the firmware with the google Chrome browser) if you are up to the task and the router has been purchased by you and is yours to keep (you don't have to send it back), and it is listed in the router database. Be aware that if you mess up during the flash process you can brick your router.



dd-wrt will make it rock solid, however there is something you must do to the firewall to make it more secure.

Answer 3

not enough information. I think you should call AT&T. If all your products are with them, it should be blatantly obvious to call them and walk you through it or send out a tech.
