RBR50 dropping wifi often

[AMG1978]

Had the rbk50 combo since 2017 no issues till now. Running 2.7.2.104 and twice yesterday and twice this morning anyone on wifi couldn’t access the internet. Not sure if they could access lan as I didn’t try. Anyone on Ethernet has zero issue. Power cycle and back online.

Do you remember when the Orbi updated to 2.7.2.104?

As far as you can tell, the Orbi WiFi signal remained active and devices remained connected to the Orbi WiFi?

No idea when the update was done. Sorry. Wifi says connected and strong but you can’t do anything. Ethernet was good to go 100%. I was actually active playing Rust a few times when the wife claimed wifi down and I confirmed it didn’t work but was connecting. Rust never lost my game connection via Ethernet

Next time it happens I hope my wife isn’t on a conf call and I have time to
Troubleshoot it vs needing a quick reboot resolution

It happened again a few minutes ago and this time my Ethernet experienced the same issue as wifi.

I confirmed I could ping 8.8.8.8 and 8.8.4.4 with 20-30ms response times but could not resolve anything in nslookup which was pointing to the local gateway IP. On the router my dns servers are google now at 8.8.8.8 and 8.8.4.4. Until today they were default from provider so Spectrum / TWC servers.

A reboot in the GUI fixed the issue. After it came online both wifi and Ethernet can resolve and go online properly. Whaaaat? Weird!

I am downgrading both rbr and rbs to 2.6.1.40 which is on netgear to download. Will see if it helps

Try a factory reset and setup fom scratch next time.

[AMG1978]

Confirmed it is related to dns on the router. It stopped working even though router is google 8.8.8.8 and 8.8.4.4

Updates my Ethernet ipv4 setting and it worked. Not a solution.

Is your NTP settings set correctly?
