Just FYI, played The Division 1 game for about two hours last night with the xbox wirelessly connected to the R1 and played with a friend with MS Chat running. No issues.

Ok, so I connected my R1 with v.207 loaded to a NG CM series cable modem and then connected my Xbox One X (Not Series X) via 2.4Ghz and logged in. Just had a long private xbox chat party conversation about NG routers wtih a friend of mine over the wireless thru the R1. Could hear and talk just fine. Last time I checked was with a different NG modem and the R1 and Xbox One at the time was all ethernet connected. Not sure if the CAX80 would have been a cause of my last reporting of the R1 and MS Xbox chat not working or something else. The CAX80 would have been in modem only mode. I'll check with some gaming and in game chat to see if that works. I'll have to come back to this after a while. I believe the CAX80 will be back in play then so I'll check again on this. Would be good if other R1 users can test this out as well if they still have one.

Just wondering two years later if this was fixed in v.207 FW?

You'll need to contact the ISP and have them send a tech out and have one wired PC connected to there modem. Have them review the ping plotter information and results. Something I mention to cable modem users so may not all apply to your ISP or configuration but give some direction: Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly. Be sure there are no coax cable line splitters in the between the modem and ISP service box. Be sure your using good quality RG6 coax cable up to the modem. Start with removing any amplifiers, signal attenuators, or splitters from the coax. From there check the line for kinks, damage, moisture in the line. Check the connectors for improperly made ends, foil touching the copper coax line, loose connections, bad/old/cheap connectors, or corroded connections. Replace them if you do. Be sure to power OFF the modem for 1 minute then back ON. https://www.duckware.com/tech/solving-intermittent-cable-modem-issues.html https://highspeed.tips/docsis-events/ Good Luck.

Something to try and see if this might help recover the wifi radios:

@jodafi I wanna confirm with you that your telnet process WORKS. I had a 2nd XR700 that I got off fleabay last year and probably spent too much money on it. It was loaded with DD-WRT and I thought if I got it, I could revert it back to NG stock FW. Ya, that didn't work entirely. After loading NG stock FW, the wifi radios become non functional. After going thru TFTP and such, I talked to someone about it and they said DD-WRT has a bad method of changing NVRAM items around on this particular model router. Would need to find something to blow that away and we couldn't find anything or information to resolve that. So Router sat for months collecting dust. YOU DID. THANK YOU VERY MUCH. After connecting to the router, it already had v.20 loaded and just enabled Telnet and after running the commands, BOOM, back up fully. Only took a few minutes. I can't give enough KUDOS to you and Kamoj as well. I've used his stuff before. Just didn't know he would have this info. Possible that this may work for other models though I can't confirm that. So this one XR700 is now working and back on NG stock FW. I might leave it on v.20 FW for now as I have a 2nd XR700 that's loaded with the Duma Beta. Ya I have two XR700s. Hehe. Please let Kamoj know this works for getting NVRAM and WiFi Radios back up and running should there be some bad state, OR if the XR was loaded with DD-WRT and NG stock FW was sent, users will need to load up v.20 FW, enable telnet, then run the R9000 commands from the telnet console and after the reboot, the unit should be fully back online and working normally. THANK YOU AGAIN. 💘💯

Did you first test packet loss with Pingplotter app on a wired PC connected directly behind the ISP modem or ONT with out the XR router being in the middle? What brand and model ISP modem or router are you using? Whos your ISP service.

What got on my XR700 with a 1Gb/50Mbps ISP service line with the beta FW loaded:

Last version was .50 for the XR700. I presume if that fails as well, the wifi radio maybe a bust. If this is the case, only option would be to disable all radios on the XR router, then connect up a different router or wifi MESH and configure AP mode on this system and connect it to the XR router. Then you can continue to use the router portion. Besides there are better wifi systems than the XRs radios. I wasn't really impressed with the used one I got several months ago. Even with Dumas Beta loaded.

Have you downgraded back to NG stock FW? The last version that was released from NG?

Try using NMRPFlash to TFTP. This is supposed to have the ability to catch the point where TFTP is enabled and send the FW to the router.

If keeping both wifi enabled, then needs to ensure wifi channels on each unit are far apart and keep the two units far apart in placement as well.

Disable ALL wifi radios on the ISP modem, configure the modems DMZ/ExposedHost or IP Pass-Through for the IP address the NG router gets from the modem. DMZ will work here and is recommended.

Should work I presume. I'll check and see what I find.

Unfortunately my ISP doesn't have anything over 1Gb yet. I asked last week and the agent had no idea if the ISP was going to put something faster out. My ISP still hasn't put up support for IPv6 yet. Sounds like someone gave some feedback though. In addition, I presume two or more devices should see same speeds if the SPF port was being used for the internet access. Though remember, all the RJ45 ports on the LAN side are 1Gb max. So you'll not see much over 900Mpbs there.
