I have Spectrum (formerly TWC) internet in the LA area. I'm connected through an Arris SB8200. The only thing I've done today so far has been to reboot the RBR850. Unfortunately, having my internet working consistently has become more important this week as my current client has essentially closed their offices and asked everyone to work from home indefinitely. I'll update this thread once I've been able to downgrade and reset my satellite and router.

MeGrimlock · ‎2020-03-10

I had already downgraded the FW on both router and satellite, so now i've factory reset the system and my FW is still on 3.2.9.2

All other settings are where they should be - now we wait

I would revert back to v3.2.9.2. Manually load the RBR then factory reset the RBR and setup from scratch. Not sure if the RBS needs to be downgraded as well. Up to you to try. Seem like the RBR is effected by the recent FW rather then the RBS is.

Still Disconnecting same devices with 2347 CTS/RTS

Thanks for pointing this out. I've always remembered mine being set to 2347, but I did just check and it was set to 64. i set it back to 2347 so I will see if that helps. Would the latest FW have set it to 64?

Hello Orbi AX Community,

May you check your CTS/RTS threshold under WiFi settings. If it's set to 64, may you try setting it to 2347 and update the thread with your results.

Thanks,
Christian

FURRYe38 · ‎2020-03-10

Ok. Your CTS/RTS values should be 2347 by default.

Let us know how it goes.

MeGrimlock · ‎2020-03-10

Even after the Factory Reset and running older firmware, same devices are still disconnecting at the same rate. I'm at a loss now. Need to wait for NG to update us on this issue.

Are your CTS/RTS values at 2347 on the RBR?

Have you rebooted or power cycled your wifi connected devices? I would do this.

What channels are you using? Auto? Try setting manual channel 1, 6 or 11 on 2.4Ghz and any unused channel on 5Ghz.
Any Wifi Neighbors near by? If so, how many?

Ensure WMM is enabled. Under Advanced Tab/Advanced Settings/Wireless Settings

Try disabling the following and see:
IPv6 and Set 20/40Mhz Coexistence to 40Mhz only. Set Short preamble instead of Long preamble modes. Save settings and reboot the router and satellite(s).

I'm not sure any of this matters. I'm having issues with wired devices as well. Why would any of these wireless settings impact my wired devices?

FURRYe38 · ‎2020-03-10

They won't. Was to see about wifi.

Thank you,

I'll PM this info after work.

Anyway, I put my old Asus router back and set my Orbi to AP last night. No more disconnects and everything is stable again.

I have been commenting on one of the other threads: https://community.netgear.com/t5/Orbi-AX/Orbi-Firmware-v3-2-10-11-seen-on-your-RBRs-FW-update-check-...

I PM'd Christian with details and my NG support case # as well.

FURRYe38 · ‎2020-03-11

If you can, help collect WAN/LAN and debug logs and send them to Christian and include them with your support ticket. Might be helpful.

Thanks for your help. Hope NG will get this fixed.

xnolightx · ‎2020-03-11

Debug logs have been attached to my NG support case. I will send those logs to Christian as well momentarily (once I figure out how).

FURRYe38 · ‎2020-03-11

Ok, if they are attached in the support ticket, Christian should have access.

Thank you.

MeGrimlock · ‎2020-03-11

Just sent you a PM Christian, thanks

My wired desktop is also having connection problems now after the latest firmware

FURRYe38 · ‎2020-03-11

Only 1 desktop wired or do others as well?

What kind of problems are you seeing?

Has a factory reset and setup from scratch been performed since last FW update?

Be sure that CTS and RTS values are changed to 2347 under Advanced Tab/Advanced Settings/Wireless Settings

I'm having the same problems as everyone else here, tried all the troubleshooting and still disconnects. This couldn't have happened at a worse time since my company went to a work from home model and my VPN drops every 5-10 minutes!

Please get this fixed ASAP.

Agreed! My wife works from home, but she doesn't need a VPN. However, our Ooma Telo keeps dropping her phone calls because of this.

Have you tried putting your Ooma device into the RBRs DMZ by chance to see if this help any?

I just put the Ooma's IP into the "Default DMZ Server" field under the WAN Setup. We'll see what happens.

Poolrad · ‎2020-03-11

Yep did that, also sent Christian a PM with my info and offered to email him my logs that I captured while debugging this while it's been happening. Waiting on a response.

While on the phone with a level 2 NG tech yesterday we reverted my firmware back to 3.1.5.23. We initially had just set the RBR850 to AP mode, but out of curiosity I went ahead and put it back to full router mode. That has completely eliminated dropped connections and I'm not experiencing any issues.

What ever was broken in 3.2.11 seems to have also been broken in 3.2.9.2. I wasn't keeping up with the firmware version numbers that my RBR850 had installed prior to having 3.2.11 but it seems it was not 3.2.9.2.

I hope this helps!
