Backhauled P9s causing slow internet across all units
I have Deco P9s connected in a star arrangement. MY ISP in the UK is Virgin.
The main deco connects to a small 5 port switch (originally a TP-Link switch, later a new Netgear one - no difference at all) and the two backhauled P9s connect to the switch. I have three Deco E4Rs (firmware: 1.4.3) connected by WIFI only.
It works great at first. Then, a couple of times a day, connection speed will grind down to a halt. The LEDs are still white. The slowdown affects all units (the usual 300mbps goes down to 1 or 2 mbps). If I simply pull the connection from the main deco to the switch and reinsert it, all is well (300mbps again) until the next time.
I have seen other posts suggesting that the backhaul functionality does not work correctly. Is this a known issue, is there anything I can do to fix it, or should I give up?
