My Windows computers:
- Desktop - connected to LAN. Error: LAN connection / Ethernet Adaptor may have a problem
- Laptop - connected via WiFi Error: "Limited Access"
- Laptop - connected via WiFi Error: "Limited Access"
All of my Windows computers are not able to connect to the Internet. The errors are written above.
The service team from my Internet Service Provider tried to connect their laptop to our LAN and WiFi, and both worked fine for them - so they assume that our problem is caused by a virus. The weird thing is, my Macbook, iPhone, iPad, and Nexus 7 can all connect to the Internet with no problems.
Also, it might be worth noting that I can boot into Windows 7 on my Macbook, and can connect to the Internet using this.
Any ideas on this? The only thing I remember doing lately that may have contributed to this problem is that I tinkered with our WiFi security settings (changed it from WPA2 to WPA-Personal) and changed the password. I've already changed the properties for all of my computers to set our connection to WPA-Personal.
Here are the things that have I have already tried (and failed):
- Disabling and enabling the LAN connection (desktop) and WiFi (laptop)
- Hard reset the router
- No changes in any proxy settings
- Reset the TCP/IP Winsock
I can't really pinpoint what virus this could be (if it really is a virus causing it) because it seems weird that it'd attack 3 computers - all of which have Antivirus programs, and 2 of which I don't even use that much. Any suggestions would be appreciated.
