Family cannot access secure sites, hotmail, mail etc. they say this has happened since they bought a wireless router.
I doubt this because the PC in question is connected direct by cat5 and since the problem, they have purchased a laptop (wireless) which has no problem with any sites.
They're running XP pro, I've read lots of threads. I have reinstalled IE7, reset all security settings, I've installed Firefox, disabled firewall, nothing works; normal sites okay.
Any suggestions I think I disabled AVG, but no joy. Any other avenues you can suggest?
