Wifi Drops - Hardwire fine.

Any luck on this? I think I'm in the same boat. Similar setup as OP: RBR850 with 2 satellites, both on ethernet backhaul.   I've had this setup for 2 years now. It's been fine until the past few ...

What Firmware version is currently loaded?

V4.6.8.2 on router and the 2 satellites.


What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?

Motorola MB7621. I'm with Xfinity.

 

What is the size of your home? Sq Ft?

3000


What is the distance between the router and 📡 satellite(s)? 30 feet or more is recommended in between RBR and RBS📡 to begin with depending upon building materials when wirelessly connected.

Around 25-30 feet for both. They're both on ethernet backhaul though.

 

What channels are you using? Auto? Try Auto and 48 on 5Ghz. Or try setting manual channel 1, 6 or 11 on 2.4Ghz and 40 to 48 channel on 5Ghz.

Auto and 48 on 5Ghz


Any Wifi Neighbors near by? If so, how many?

No. I'm in a single family house. I can see some of my neighbors' networks but signal is much weaker than mine.

I was just poking around the logs on the Motorola modem. I see these messages that look suspicious.

Also, I take back what I said about hard wired devices being fine. I do recall now that sometimes they have problems, too.

    30 feet or more is recommended in between RBR and RBS📡 to begin with depending upon building materials when wirelessly or ethernet connected.

     

    Also try turning down the power output of the RBRs wifi radios from 100% to 50% and see if this changes anything. Under Advanced Tab/Advanced Settings/Wireless Settings

     

    Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly.
