So for the last 3 days my WiFi signal has become slow and intermittent at best, at worst it is non-existent. This I find strange as my WiFi has typically been very good, especially as Virgin say that my router is working just fine.
Some devices are incredibly slow to load or play videos. Other devices cannot connect to WiFi at all. The WiFi on my phone is serviceable, but many Web pages won't load and give me the error message 'Access Denied', this has never happened before.
I could really do with some advice, my network log is below if anyone can make sense of it.

The issues are with both WiFi and ethernet connections. It's a Hub 3 and the light on the front of the hub is solid white, no other lights.
I'm wondering if it is a fault with the hub.

OK nothing amiss in those stats, that and a constant white Hub light suggests there are no network disconnections occurring - but to nail that we need to see the BQM
Are you sure its dropping on an ethernet connected device - if so have you tried on a different device and with a different (new) ethernet cable?
on 03-12-2021 16:02
Yeah it's definitely dropping via ethernet. For example my PS4 is connected via ethernet and cannot connect either by LAN or WiFi. However if I use 4G to Hotspot my phone to my PS4 it connects just fine.
Similarly, my phone is incredibly slow when connected to WiFi and won't load most Web pages. However when I connect to 4G or a different WiFi network it works fine.
Could this be fixed by replacing the router? I have an engineer coming tomorrow morning, so hopefully he can find the source of the issue.
