We have put together a short survey to capture your feedback in terms of what BT can do when you experience home Wi-Fi issues. We would appreciate it if you could take a couple of minutes to complete a short survey. Read more from here, Fix my home Wi-Fi
There have been issues with ubisoft games but so far no issues for me with Landmark or ESO.
What are your line stats?
I appreciate the link, but it seems to be 41 pages of problesm with no working fixes/solutions - have BT said if they are doing anything to fix this as 5 weeks of this **bleep** is far too much considering the price we pay.
Have you tried doing any pings or tracerts to the servers in question?
Have you tried a vpn just to see if that's the issue?
Are you using wired or wireless?
If wireless have you tried changing the wireless channels?
Have you tried totally uninstalling any firewalls and/or antivirus you have installed?
The reason I posted the link was to show you the extent of the problem and that it is most likely not a problem with your equipment or set up which should save you trying to sort it out at your end.
