My PC is hard-wired to the router, and the router DNS settings are for OpenDNS (208.67.222.222). Two days ago, everything was fine, then yesterday when I switched on my PC, it wouldn't connect to the internet. The router was working OK.
With the help of my ISP, I found that the DNS setting in the computer was for a specific address, not "automatic". Having reset that to automatic, it's fine again, but my question is - how could the DNS setting in the PC have changed, apparently by itself?
I can't tell you the specific address which was in there, because I didn't think to write it down, and now the field is blank, but I think it may have started 177....
