Model: Archer A7  
Hardware Version: V5
Firmware Version: 1.1.0 Build 20201120 rel.50399(5553)

TLDR;

Test Computer -> cat5 cable -> New Router -> Switch -> Bridged Router -> Router -> Spectrum Cable fails

Test Computer -> WIFI -> New Router -> Switch -> Bridged Router -> Router -> Spectrum Cable works

 

I bought a TPLink AC1750 router as part of me hardwiring the house for ethernet. I can get some wifi, but prefer the wired if possible. Anyway, changed it to access point mode, changed the admin password and SSID name and not much else. I connected the incoming internet line (WAN port?) to a switch which is connected to another router in bridge mode which finally connects to the incoming line from Spectrum. As I type this, I anticipate the comments on complexity. I'm with you, but bear with me.

 

Anyway, before hanging the new router in it's new home, I tested another computer against it. This test computer can do a wifi connection just fine to the suspect router. But if I connect it via a wire, it fails.

My journalctl shows the following

 

Dec 15 00:16:00 woodsman-office-closet NetworkManager[14858]: <warn>  [1639545360.8675] dhcp4 (eno1): request timed out

Dec 15 00:16:00 woodsman-office-closet NetworkManager[14858]: <warn>  [1639545360.8767] device (eno1): Activation: failed for connection 'eno1'

 

When I connect the same cat5 cable from the test computer to another router, it works fine, so I ruled out the cable.

 

What else should I check?

 

Test computer is Linux FC30.

@woodsman7452 

 

So you are going from a router to a bridge router to a switch to a 3rd router.  This is a werid setup.  My first question would be how is the bridged router bridged?  Is it still routing or just passing through traffic like a switch?  Is it using WDS bridge and acting like a range extender?  The new router, which i assume is the TP-Link router, what mode is it in?

 

Let's start there.
