This issue started a month or 2 and lasted for over a week. Then it dissappeared until the last few days (yesterday being the worse...lasted for around 2 hours).
The issue is - when trying to use the browers (on 2 PCs connected via cable (2 seperate ports) and 2 wireless devices) we get 'Server Not Found'. This happens intermittently (mostly in the evenings) and lasts around twenty minutes too a couple of hours and typically only occurs once or twice (that we know of).
However on third party software (Steam, Mobile Apps - inc Youtube & Twitch) the connection is fine, downloading at max bandwidth (70mb). So we're getting direct downloads, but when trying to access online sites the servers aren't found, as if not connecting or blocked).
Any advice? or people suffering the same issue?
