My HUB 3 reboots when using my PC for browsing but if I turn on VPN the connection is stable.
I have tried different browsers to access web sites which may be stable for a few minutes then reboots without warning. This started about 2 months ago and have had two engineers out to try and fix the problem, the first removed an attenuator from the input of the router then said should be ok, the second replaced the router, removed an attenuator from the junction box outside my house and replaced a splitter and again said should be ok. If I turn on VPN (I use NORDVPN) then the router is fine and works well and stable all day, as soon as I turn it off when I need to access location sensitive sites (TUI Holidays etc.) we may run a few minutes then back into re-boot mode.
On reboot, the power light initially flashes, then goes red then all lights go green and go through the process of reconnection which tends to take an age.
I am connected by CAT 8 ethernet cable but have tried disconnecting with wifi only, also disabled wifi card with ethernet only but result always the same.
