Powerlines and Firewalls - A strange coincidence of high security and LAN disconnections
This article is about a connection problem of TP-LINK powerline adapters, seemingly solved with a rather strange solution! Before I get to that, let me describe how I am using my powerline adapters: I have a small home network of computers, smartTVs and cameras, served over 4 powerline adapters: a pair of TL-WPA4220 adapters along a pair of rather old TP-LINK-TL-PA211-AV200's. I am not using Wifi, because I have two small kids and no need to risk their health with possible implications of high frequency transmitters near them. Also, as our rooms are far away located, installing normal CAT5-6 LAN cables demands ruining the walls. So my only viable option is powerline adapters. My four powerline adapters were working fine with each other for over four years, providing my home with an almost cable-quality LAN. Speeds were up to 140mbps between the two old adapters and around 260mbps between the two new ones. These are maybe not great to transfer large files, but are
