today something strange happened.

all of a sudden my wired port on my pc stopped working like ity was disconnected.
i checked other wired ports on my router and they seem to be down as well(lights on ports were out)
router was up and runnning and wan connection was still working as well as wifi,

this is what showed up in the log.
at that time nothing was happening on my pc and it was not shutdown
anybody any ideas

Take ports 5 to 8 out of service and just use 1 to 4. Those messages are from the internal switch that controls those ports, and it looks like it may be failing.
 
ok, but switch port 3 logical port 11 maps to physical port 1 which is connected to my pc.

at the time of the problem both port 1(pc) as well as playstation(port5) had problems
at that moment i was doing something on the ps4, i think changing the video output

so could things on port5 cause problems on the rest of the ports(1-4)

if that is the case i might change some things so that ports 5-8 either do not get used or get used by appliances which are static
 
Problems with the switch controlling ports 5-8 can, and likely will cause problems elsewhere, from the gui to wifi. Stick to 1-4 for now, see what happens.
 
On Monday evening, I had exactly the same experience on my W11 desktop PC (for the first time) with an AC86U. It was like I suddenly had no network connectivity - or so I thought, because the first thing I tried to do, was access the web interface of the router, but the page wouldn't render.

I couldn't work out why my router had stopped responding, checked it from my (WiFi connected) phone and it appeared to be fine. I put this down to a combination of 1 or more of:

1. Event viewer showed: "Name resolution policy table has been corrupted. DNS resolution will fail until it is fixed. Contact your network administrator. For more information: read policy table for rule {5abe529b-675b-4486-8459-25a634dacc23} failed with error 0x57" - so this was kind of a Windows side failure, that would explain my ethernet connection apparently going down.

2. Edge appeared to be getting updated at the time - and I am always suspicious of impacting artifacts when that happens.. (Fun fact: You know when your PC goes screwy - for no apparent reason? Outlook -> Office Account -> Update Actions -> Update now - and I bet you have an update waiting)

3. For the past two days, on this PC, I have been unable to access the web front end of the router - as there is no HTTPS and Edge/Chrome is flagging it as insecure - although it is still accessible in InPrivate mode. However, this morning, all is fine - and I can't identify anything that has obviously changed.

Bottom line, I am only saying this because it might not necessarily be a switch problem at the router side - as I had the same symptoms (caused by Windows) AND I see other folk reporting that after an update to 386.13 they couldn't access the web front end either - so I wonder if that coincided with a similar client side problem?

This message is worth what you paid for it etc - and I could be barking up the wrong tree (often am).
 
Is the router rebooting It may be similar to this issue
