New Router, some devices won't connect, "Password Incorrect"

This is a strange one. The router in our master bedroom went out a few weeks ago. Well, it "worked", but wass exhibiting a strange behavior where it kicked all devices connected to it off the network about once every 5-10 mins. Kind of a pain when you have a bunch of smart home devices connected to it. Since I have 3 other wired access points, I simply removed it from the equation. From a connectivity point of view, everything was fine. But the signal was a little week. The MB router was also the one that provided signal to our back porch/back yard.
So I jumped on amazon last week and picked up a TP-Link AC4000 and moved the TP link Archer AC3000 up to the bedroom. For the most part, I made the switch over, and there were no problems. However, a few devices wouldn't connect to the network, my wife cell phone, a couple of smart home devices on the 2.4 ghz network and 1 Alexa device. I kept getting an ""Password Incorrect" message, when the password on the network was the same. I cycled the network several times, forgot the existing network on the effected devices, etc, etc. Nothing worked to get them re-connected. Finally I gave up and went back to the last known working configuration. What I didn't try was connecting the new modem as an access point in the master.
FWIW, our network consists of a cable modem, primary router and 3 (2at the moment) hard wire access points over the existing cat5 cable. Roughly 4500sq foot home over two stories (Upstairs and basement). Except for the kid wearing out Youtube this summer, we're pretty light data users.
Any network experts have any idea on what was up with these handful of devices and things to try?

Those devices might not support the encryption method being used by your new router. For example, you router might be using WPA3 and those devices only support WPA2. Try setting the router to WPA2 and see if that fixes the problem.

After striking out a second time, I returned that router and replaced it with another one. After 10-15 mins configuring it as an access point, things appear to be working without issue. Getting 200+ Mbps in the master, which is about what we pay for. That also baffles me a little bit because it's hard wired with Cat 5 and the max thru put should only be about 100 Mbps. The only thing I can figure is it's connected to the primary router via a wireless bridge/mesh (that I didn't set up)? But I don't even know if that's possible.
I think it was a hardware/firmware problem with the previous router.

quote:Probably cat5e but even cat5 will probably do gigabit if the run isn't too long. The hardware doesn't know what type of cable is attached, it just tries the fastest speed it can. If it works, great, if not it'll try to negotiate slower.

The house was built in 99 so I'm pretty sure it's c5. But the run is only about 30' thru the floor so maybe that's it? Everywhere else I only get 100 mbps thruput, but those are older routers. I might do some a to b swapping (office to master) and see what happens.
ETA: So I did a network check and I'm getting 230-250+ Mpbs everywhere (well all the network ports that are hardwired and in use) except off the office Ethernet cable (I tested it with two different routers with the same result). Funny thing is, that's the shortest run of them all. The network distribution panel is in the basement literally directly under me. Who knows?

Could be a bad termination, kink in the wire, interference from high voltage, finicky NIC, or whatever. Unless that run is stapled I would probably get some cat6 and use the cat5 to pull it through.

Wanna hear the fun part? It's all five cable bundle, 2 cat5's telephone and 2 coax cables....

I was going to ask if the routers had the same SSID, because that can screw up device authentication with some router OSs. AP mode on the secondary router almost always worked well with me.
MFers are lazy. When I ran wire (including speaker wire) pre-drywall, I stapled everything separately (if it needed to be stapled to the 2x4s.)
On the positive side, you probably have zero use for coax now. You can also pull multiple Cat6 with the bundle. I had two main routers in the house, with nearly everything connected to the living room router, and I had two Cat6 running between the routers.
I bet they zip-tied the bundle in the wall, didn't they?
ETA: I hate fish tape. Die.

This is (basically) what's in our walls.
In reality it would be much easier to pull a line from the basement to the attic and back down into the wall. I have access to the top plate of the office from the attic.
