Hi,

If you have factory-reset the router, then connected your wireless devices and they disconnect within 10 minutes, then it seems there is a technical issue with your particular AX6000 unit.

If you still have warranty left, then you should probably contact the place from where you purchased the router and ask for a repair or replacement.

Thanks for the response woozle!

I continued playing with it...

once the LAN cables were removed, things went back to normal... does this even make sense??? is there a link between a potentially faulty LAN cable and wifi password??

  @wertzy 

I don't see any obvious link between the LAN ports and the problems you have.

Does the AX6000's Wi-Fi only work if no LAN cables are plugged in at all or is it only one particular cable that causes the Wi-Fi password problem?

If you can trace it down to one particular cable, then test if swapping out that cable makes any difference.

While you are at it, can you also check if your LAN cables might be routed very close to (i.e. touching) something that generates strong electromagnetic fields, like a large power supply / transformer or power cable of an appliance that draws big amounts of power? (i.e. >1000 Watts or so)

In case there is, then try to achieve a few centimeters (couple of inches) of physical separation between those and the LAN cables.

Again- thanks for the response.

I will check and report back.  It is very strange...

I hooked some of the cables back, and everything was fine and stable... will hook all of them and see what happens.

There are no large power consumers near the router... just some external hard drives

Thanks again for the help!
