TP kit drops bandwidth and after two days
Bought this kit brand new and I've suffered problems with it. My landlord previously purchased a Devolo powerline kit but that created jitter when watching movies hence the change to TP Link. I was running an AV600 at the Plusnet router and a TP-Link wireless router at the other end one floor up and it's been quite fine. We took out the Devolos and put in the TP Kit where the TP Link router was replaced by a Linksys network switch and the AV600 coming into the room was replaced by the small powerline plug from the kit and the bigger extender AV1000 on the landing. Cloned the Plusnet Router SSID and labelled the 5G seperately. Then the problems began, we was getting good speeds and then the 5G would suddently drop to 1Mb bandwidth and I was unable to access it via IP address to do anything. So it was reset and everything came back up only to go back down days later. So I've done the following where this result has been the mainstay of the network
Changed the 5G SSID to the same as the 4G - No change to the problem, my laptop would access the 4G on restart and I'd get good signal but dropped after a few days when the laptop started using the 5G.
Removed the AV600 from the Plusnet router and exchanged it for the small plug from the kit thus putting the AV600 local to my Linksys switch - According to the TP-Link PCL map, I was getting red lines of circa 11Mbps to 23Mbps to and from the small plug but everywhere else on the network was around 450Mbps, even the longest distance was 250Mbps but it still died a few days later. So the AV600 was put back and connected to the Plusnet and no joy, the red line stayed at 23Mbps but remained in one direction only.
So far, I have disabled the 5G SSID radio to see whether it decides to die again on the 4G or stay fine. As far as the network is concerned, my next option if it doesn't is return the WPA Kit back to the store, keep the AV600s and buy wireless routers to connect to them. Under the believe that these powerline wifis can't do two things at once but I know a non-wifi powerline is absolutely fine as I have been running them in line with a router for years and had no problems at all.
