Plusnet isn't any better. Their DNS servers are obviously stuffed (technical term), while I can get online with the laptop and tablets/phone, none of my PCs can, though there is allegedly no problem - ping and tracert (using IP address work fine) but domain names just fail.
For weeks I've had to run a network cable through the house from hall to office at the back because my wireless bridge is not getting the necessary info back from Plusnet's poor service. Don't even mention their mobile (EE) coverage!
