I have an Rt-AX88U on 388.1 fw and a RP-AC1900 on fw 3.0.0.4.386_49703. If i connect the AX lan to the AP wan, I can get the ai mesh to connect, but then it immediately says the connection is weak, even though the unit is 1 foot away (and still plugged in at that?). If I disconnect it, that's it, it's never connecting wirelessly, just like it couldn't be found wirelessly. I'm kinda at my wit's end with this. Any help would be really appreciated.
