Nighthawk AX4 in AP mode connect to XR300
I hope this is the correct place to post this. I have a XR300 router. I have connected it with a LAN cable to AX4 router that I setup in AP mode. The XR300 will not connect to the AX4 router. (My...

I might look at going with a wireless solution because the cable will be very hard to replace.
How much speed do you actually need in this building? How many people are using the internet there at the same time? 100 mbps is slow for copying really large files, but it is ok for web browsing, email, wifi calling, and even video conferencing and streaming. So one option is to just live with fast ethernet speeds.
On replacing the cable - It might be easier to run a new cable (perhaps in another conduit) than to replace the old one. Though that depends on what else is in the conduit. If it is only the one cable, then it might be possible to pull a new cable through it (attaching a thinner nylon cord to the existing cable, pulling the existing cable out - leaving the cord in the conduit, and then pulling the new cable using the nylon cord). There are several youtube videos on this topic that you could explore. Another option (requiring ethernet transceivers on both ends) would be to pull fiber, which is thinner.
As far as wireless goes - there are point-to-point wifi solutions that can be used as a substitute for the cable (one unit on each building, with line-of-sight between them). I doubt you'll get gigabit speed, but you likely can get something faster than 100 mbps.

The WiFi SSID is not material to the discussion. There is no harm in having WiFi routers that are 100ft apart having the same WiFi credentials (and certainly makes it easier to move a mobile device between them). As long as you are aware that they remain separate WiFi routers. A mobile device will not actually roam between them as it would between units of a mesh WiFi system. What will happen is that performance when connected to one router will drop (and drop) until finally the device "gives up". Drops the WiFi connection as unusable. and begins searching for a suitable WiFi connection.
When the Spectrum router is replaced by the XR300, does the XR300 "work"? i.e.
- The XR300 reports having internet access.
- User devices connected to the XR300 function correctly?
Interesting that the LED on LAN ports blinking red every 5 seconds is not a condition shown in the R300 user manual:
100 ft. of Cat5e Ethernet cable is adequate for this application, provided that the cables are terminated correctly. As the problem is described, it appears that "something changes" when the AX4 is connected to the Spectrum router or the XR300 router. Does this 100ft Ethernet cable run directly from one router to the other, or are there any patch cables or switches involved?
