I have had the VR2800 for nearly one year.
I get the occasional connection problem which I have been trying to diagnose without much success.
We are with Plusnet and we get approx 20Mb down and 6Mb up.
We have approx 15 devices connected (all wireless). Mobiles, laptops, firestick, sonos, etc. All 2.4GHz except for the firestick (5GHz). No wired devices.
The symptom is that a video (or even just audio) call will suffer a connection loss. It was bad yesterday - I lost connection 5 times in 90mins. Other devices were impacted. Ended up powercycling the router. After the restart it seemed to improve.
I have a command prompt where I continuously ping the local router address. The response time is normally low (<5ms), the occasional peak coinciding with other activities. When I lose connection on a call, the pings timeout for the duration of the problem. Given that these pings are local (to the router), does that suggest a WIFI problem rather than a problem outside of the house?
