I ran a test from your website.

All devices are showing up with poor signal strength, both hard wired and WiFi devices. All 3 gaming PC's are wired directly to the router.
The connection has been getting worse over the last month and is now making online games virtually unplayable. I am regularly getting disconnected from game servers, up to 10 or so times an evening.
I work from home, connecting into my work station remotely, and i see noticeable slowdowns occasionally during the day, but the biggest annoyance is in the evening as game servers are far less tolerant of poor connection that my work connection.
I am also seeing YouTube video stopping and only the sound remains until the picture can catch back up.
The connection had been poor previously and a new router was provided to replace my old hub that was several generation old, this made the previous issue go away. Could this router have developed an issue, or is there a problem external to our property?
