Current setup: VM 200 mb fibre connection, connected to a Tp Link AV600 homeplug (TL PA4020P). A few devices in the house also connected with other TP600s, all working fine. Office / shed at the back of the garden also has a few TL PA4020P and one TP-Link TL-WPA4220. The office is electrically connected by an armoured cable to the fuse board, with it's own circuit breaker in the shed / office. Distance is about 60 - 70 feet including runs. Issue: The homeplugs in the shed / office drop on a really irregular basis. They can rock solid for a few weeks, then go to hell for a few days where I'm just rebooting everything all day. I've updated the firmware on all devices, tried to isolate different devices, removed all devices and re added using the TP software and the drops still persist. It's always when 'er indoors is WFH as well! Solution? Do I either look at a different Homeplug brand, install a wireless repeater router near the back of the house or just bit the bullet and get someone to install a Cat 5E or 6 connection? Any advice greatly appreciated!
