Good evening

I am wrting to you i hopes of getting some help

I live in Portugal and i recently bought 2 tp link re450 repeaters/AP .

I have a CAT6 structured network at home all connected via tp link gigabit switches.

My ISP's router wifi is off

Both re450's are setup as access points and get their ips from my ISP (NOS)'s router, so their DHCP is off.

Both have same SSID and password for 2.4 and 5 GHz.

Summarizing, the router acts as DHCP server, RE 450s are set to AP mode, with DHCP off and auto ip detection.

I have tried different SSID's for both APs

I have attributed an ip to each ap vinstead of having it being auto detected.

Both AP's will at random, seemingly lose ip connection to the router, their ip becomes innacessible.

Today my own computer could not get ip ....

What can i do, what settings should i look out for that could be causing issues?

Thank you
