I have at home a network of 3 PCs (all Windows 7), 4 cellphones, 2 gaming consoles and a printer connected to the same router (Netgear D7000 Nighthawk); every single device is able to connect to the Internet and to the home network without problem, but I have a 4th laptop (windows 7 32 bit) which can't connect to the wifi, only via LAN cable. It can establish a connection to the Wifi network, it can see and can be seen in the home network, it pings the router with a lag of 2ms but it doesn't connect to the external network. It can't ping any external website as well as any external IPs, giving me a "general failure" error. Here's what I've tried so far:
- Flushing DNS list
- Flushing IP table
- Giving it manual IP address and DNS
- Giving it automatic IP address and DNS
- Disable IPv6 connection
- Completely removed and reinstalled up-to-date Wifi drivers
- Temporary mode with networking (is it called temporary mode in English?)
- Changing DNS at the router (pretty much pointless since every other device connected to it doesn't have a problem with the network)
- Giving it a fixed IP from the router
- Disabling Avast antivirus, Avast firewall and Windows firewall
- netsh interface ipv4 reset and ipv6 reset
- Voodoo magic
- Begging
- Hitting it with a baseball bat
- ???
Nothing of the above has worked so far. It's a computer that sits all day on the desk and act as a home server for my external drives, so I don't install any program on it, it just sits there. I know that I could just format it, but it took me so long to configure it as a multimedia server, and I don't really fancy doing it again. Some technical details:
Windows 7 32 bit, Intel core i3 M 350, 4GB RAM, Intel Centrino Wireless-N 1000.
I am completely at loss, any idea will be much appreciated, thank you.
