i got an big problem with 2 zyxel NR7101,

It allays loosing connection to the LAN networks after some hours, sometime days, randomly

It only can be resolved by reset to default and reenter all data, then it works for some time
the WAN connection of the router will still work, but it will not send any data to the LAN

Also the ARP table of the IP4 protocols are near empty

I got exactly 2 units with same problem

I have allready the newest firmware on it, from telekom

It have an DHCP server on Bridge 1 running and an Zyxel WAC6552D behind
the system runs before for years without problems

I also got an fixed IP from my provider now,

But i think its an Communication problem with the LAN

Und the WAC hotspot are only connected 5 arlo webcams

    Any network switches in-between that could be causing issues or any old/damaged ethernet cables? Are you more than 100m away from the NR7101? How old are the NR7101 units as sometimes a failing PoE injector could cause weird issues.

    worked 2 weeks now,
    Now same problem again 🤬
    i can access the router over the internet and LAN, but it will not transfer data to next WLAN-Accesspoint WAC6552D, no trafic shows in ARP table to LAN-IP4
    reset to default works for few days, then same issue, tryed different 7101, allways same problems
    this looks like firmware issue
    now i have ordered an 7201 and an DLINK 5G router as replacement
