Wired backhaul
I have an m5 system with 6 nodes, three of them are on a wired backhaul with cat 6 cable to a tp link managed switch on a 500mb line
Last year I had a lot of problems wih the "abnormal WAN port speed error", which limited my download speed to around 90mb. After much discussion with TPlink I resolved it by replacing a cable, and swapping round the decos so a different unit was the main deco.
all worked fine until about 4 weeks ago the dreaded wan port speed error occurred.
I restarted the system and the error went, but now my three nodes that are wired back to the switch are not showing as connected via Ethernet in the app.
I have tried everything including replacement of all the Ethernet cables for brand new. One will work, and the then the other two will stop. I'll unplug restart and then another one will work and the others won't.
sometimes none work!
Anyone got any ideas what could be going on?
