Hi Vikki,
It does not happen as often as it was before the tech come out, but still happens.
It can happen when I am within a few foot and direct line of sight, as much as on the other floor of the house.
It happens to some of the devices on WiFi, but also noticeable on wired devices as well. Theee is no discernable patten though as not all the devices are active at the same time.

Switched to Modem Mode: 21 May
Current set-up: SH3 in Modem Mode - TP Link Archer AX50 in Router Mode - M200 Fibre / Maxit TV - Talk Weekends (Now via the SH3 -which is great in a power cut)
