Asking for some suggestions here
Recently I just upgraded to 1Gbps fiber plan, with symmetric speed
I'm using UCG Ultra with Asus AX88U as AP
However, I noticed a problem...whenever I restarted the UCG without restarting 88U...I wont be getting IPV6 from clients under the AP
Probably be changing out the AP, but U6 Pro doesnt seems to be that good for 1Gbps plan? Also, my house is right beside the airport which means 160mhz would constantly getting DFS and fell back to 80mhz
Looking for some suggestions for hardware
I have 6 wired devices, 10+ wireless (half of it are wifi 7 capable)
Need a powerful AP for the front of the house, while having an inwall AP at the back for a single room
When DHCPv6 PD change, a properly functioning router will multicast a new Router Advertisement.
If only WiFi client have the problem, then it's very possible the Asus block it due to some configuration.
There are quite a number of setting that reduce airtime utilization like multicast enhancement, which basically transmit only selected frame and to each client independent instead of using base rate.
ARP proxy learn the ARP, cache them and will eat up all future ARP transmission and just read from cache.
You need to try disabling those one by one till you found the culprit. But sounds like a firmware bug in Asus.
