What happened to my posting

Mfr/Model: No switch exists between the RBR50 and RBS50s. All wired devices connect to a TP-Link 24p unmanaged switch, and the switch is connected directly to a LAN port of the RBR50. Both RBS50s were connected directly to RBR50 LAN ports.

Daisychain: Yes I had it enabled (checkbox ticked).

Size of home: 2250. RBS50-1 and RBS50-2 are both about 35ft with intervening walls. CAT6 path is obviously longer.

Storms: I have IP reservations for the RBS50, set to .2 and .3. I don't believe there are any IP conflicts; everything is DHCP; and I have about 6 total reservations defined.

Bear in mind, this system was working fine for many days (maybe 1 weeks?) after the FW upgrade. But at some point, downstream bandwidth dropped dramatically (upload speeds not affected), and ONLY on devices connected via WiFi to either RBS. The condition remained this way constantly. When I forced a WiFi connection to the RBR, it's bandwidth was NOT affected, nor were any of my wired devices, in either upstream or downstream.

BTW I did the FW upgrade while in the wired backhaul configuration, and did not do any special manual power cycling/resetting. I understand that you advocate the brute force wipe everything clean method but I did not do that.

At the moment I've got the wired backhaul disconnected and I've rebooted a couple times. Switched off daisychain also. Apparently I don't need it, since my backhaul status still shows "GOOD" on WiFi. No issues seen at this point with WiFi backhaul.

I REALLY need some stability in the network because I'm planning to drop my Dish Network and switch to YouTube TV streaming service in the next month, so even TV viewing will then be dependent on internet access. Technically I don't even really need a mesh system because I've got the CAT6 wiring I need to just use APs. Whatever; this is where I am right now.
