Streaming from network devices stops due to constant DHCP lease renewal?

I've had nothing but trouble with the orbi system but mostly we have battled to a stalemate. The one remaining thing I can't tolerate is constant dropping of streams from Apple TV, Amazon Fire sticks...

As a sanity check I used scapy to query DHCP and found only one response on my network... so it's likely not caused by a rouge DHCP server on the network unless it's popping in and out of the network somehow.

Have you tried a full factory reset on the system and set up from scratch?

Set up some IP address reservations. I would change the IP address pool from default to .100. thru .200. Then add reservatsions for your devices.

Also power cycle your ISP modem OFF for 1 minute as well then back on.

Set manual wifi channels, 1, 6 and 11. Streaming should be happening over 5ghz if your not streaming wired.

I haven't tried a factory reset/setup from scratch on it yet. I already have set reservations for the Apple TV but I do actually want this to work with dynamic reservations as well... either way it doesn't help.

At this point I am going down the rabbit hole. I've telnetted into the thing and oddly the lease file it is supposed to be writing out in `/tmp/udhcpd.leases` is empty. The udhcpd configuration is set as:

pidfile /var/run/udhcpd.pid start 10.0.0.2 end 10.0.0.254 interface br0 remaining yes auto_time 5 lease_file /tmp/udhcpd.leases option subnet 255.255.255.0 option router 10.0.0.1 option dns 10.0.0.1 option lease 86400

However the lease file at /tmp/udhcpd.leases is empty even though its configured to be written every 5 seconds (seems agressive but whatever). I'm looking into why that would be now...

Lets try a factory reset and setup from scratch and change the default IP address pool as suggested...

Let us know how it goes.
