So yesterday I was having some internet issues and restarted the router. Now, whenever I try to connect to the computer on my desktop, it will either be stuck on connecting or it will connect with limited access (yellow exclamation point). However, the laptop that I have connects to the internet fine. I've tried restarting multiple times, restarted the router (both unplugged and held the reset button for 10 seconds), and did a system restore. Nobody else in the house is having an issue. I do not use an ethernet cable. In the device manager, there is a yellow exclamation point next to the Microsoft 6to4 Adapter, the ISATAP adapters (two), and the Teredo Tunneling Pseudo-Interface adapter. I have tried uninstalling and reinstalling all of these to no avail. When I go into the network adapters, there are three available; Local Area Connection, Wireless Connection 8 (DW1525 (802.11n) WLAN PCIe Card) and Wireless Connection 9 (Microsoft Wireless WiFi Miniport Adapter). The only one that ever connects is 8, but with limited access, and frequently cuts out. I've tried googling the problem rather extensively but thus far haven't found an answer, so any help would be greatly, greatly appreciated Edit: Also, firewall is disabled. Edit 2: I can access the internet when the encryption is TKIP, but not when it's AES, as it should be. TKIP is ridiculously slow.
