AX6000v1: Wired devices slow to connect
A couple months ago I purchased an AX6000 (which I later discovered to be hardware revision "1") to replace a miserable old Netgear, largely because I was going to be traveling for several weeks and needed the OpenVPN server function. The good news is that the VPN server performed quite well while I was on the road and I was mostly able to do what I needed at the time.
I installed the router with somewhat minimal testing before leaving for a trip, though I was excited about having eight GbE LAN ports because my previous routers have never provided enough physical connectivity. Soon after returning home and beginning to tinker with it I began to realize that all equipment physically connected to the router via cable is experiencing a rather irritating delay before being granted network access. The behavior is reminiscent of issues with autonegotiation and is most noticeable when powering on my living room television or PS5 - both of which sit at a "this feature is not available because you have no network access" screen for 10-20 seconds before finally reporting a successful connection.
Otherwise the router appears to behave fine. Logs available via the web management portal provide zero useful info. I contacted TP-Link support via chat and was instructed to wire a laptop to the router and get the full speed test results there, and then with the same laptop connected directly to my modem. Okay, fine... but my chat session timed out before I could report the results and frankly it's not going to help me here.
Any advice?
