Hi everybody

I am new in this community. I take the opportunity to say hello to everybody and apologies if I had to introduce myself in any specific thread

I changed the ISP router with an Archer AX53 as main router (PPPoE credentials) and I have Archer AX72 as acces point in mesh with a range extender (RE700X). AX53 is not in the mesh network as it is ot a big home and I prefer AX72 as main mesh device with the range extender. I have two points to ask some help:

1.- AX53 was working normally but suddenly it blocked Discord (quality went down dramatically) and acces to some application like League of Legends. With the ISP router it works. Could it be any "automatic" configuration from AX53?. My ISP shares public IP with other users (CG NAT) and I do not have acces to ports so I have not managed them

2.- I can see AX53 and the extender in tether app but AX72 is local and cannot be seen via Tether outside from the network. Why is AX72 "local" and not "cloud"? Could it be because AX72 is in acces point mode??, or is a mistake on my side on AX72 configuration??

Thanks in advance for nay idea that could help in both points
