If it is enabled on this machine, then DNS resolution over wireless fails, even though it says “Not connected.” If it is disabled, everything works. This is the Microsoft Virtual WiFi Miniport Adapter. But what? Even specifying the addresses of known good DNS servers in IPv4 properties did not fix it.
Investigating further, I found that it was possible to ping remote sites by IP number, but not by name. I tried various things – reset the TCP/IP stack, updated the Realtek wireless lan driver, even tried with a different wireless access point, but still it did not work.Ĭuriously, a wired connection to the same router worked fine. Nevertheless it could not resolve a ping. I did the usual ipconfig /all and noticed that everything looked OK on the wireless adapter – IP address, default gateway, DNS servers. At least, it connected but there was no internet connectivity.
Today I was asked to look at a Toshiba Satellite Pro laptop that would not connect to a wireless network.
