R7800 5Ghz Highly Unstable with Firmware v1.0.2.52

R7800 5Ghz Highly Unstable with Firmware v1.0.2.52

Upgraded my firmware yesterday, and sat down this morning to an extremely unstable connection.

 

Video and voice chat and real time games showed extremely violent drops in connection, such that I would miss sections of conversations and characters in games would teleport around violently.

 

I connect using a Netgear A7000, and watching the genie application showed me that the connection was frequently dropping from the 390-790 Mbps range down to 48-54 Mbps, though only for the time of a single refresh (maybe seconds?)

 

I have since downgraded back to firmware v1.0.2.46, and the issue seems to have gone away.

I also had problems on my R7800 after updating the firmware to V1.0.2.52.  I never had problems with any of the other updates except this one. After the update, the router would lose connection about every 15 to 20 minutes. I'm pretty sure there is a bug in this version (V1.0.2.52) so I have reverted back to V1.0.2.46. So far, no disconnects but I'll continue to monitor the stabillity of the router with the older version and report back to the community.

No issues regarding WiFi here in my testing so far. Try factory reset and don’t use backup config, as in manually reconfigure. Sometimes changes can cause issues with old configs. I factory reset after updates to avoid issues.

Thank you for the excellent and timely advice, I didn't even think of that after the flawless past firmware updates. I'll give the new version another try tomorrow, my eyes are getting buggy now.

I did not try a full factory reset, as resetting all of the fixed IP's and the like I have is kind of a pain. May have no other choice though.

 

I did try the following troubleshooting steps:

 

1. Moving around Router and Adapter antennas.

2. Running 5Ghz on it's own (making it so SSID didn't match with 2.4Ghz; my normal operating mode is they match)

3. HT160 off/on

4. Changing the 5Ghz channel

Yeah I keep asking them to give us a modular backup option. Like Attached devices icons/names and reserved IPs.

I also experienced where the names of my "Attached Devices" were erased with V1.0.2.52. I also experienced disconnects every 15-20 minutes with that version. I did a factory reset as suggested by Avtella. The disconnects disappeared but I had horrible download speeds, somewhere in the range of 10-12 Mbps even after I manually configured the router to it's previous settings. Nothing I did in the past 2 days helped the speed, even called my serice provider to run a diagnostic on my cable line. Downgraded back to V1.0.2.46, did a factory reset, reconfigured the router and was back to normal. Download speeds now back to 233-236 Mbps as before. I have the 200 Mbps Plan. Never did figure out what the problem was in V1.0.2.52 but I know for sure that it is buggy on my R7800. I always install the newest version of firmware on the router as I feel my system is more secure but I'll have to wait for the next upgrade because this latest version is not fully campatible with my R7800.

I also noticed two issues.

 

5G drops each morning. requires a restart.

Attached device names are gone.

Re: R7800 5Ghz Highly Unstable with Firmware v1.0.2.52

I upgraded to v 1.0.2.52 a few days ago, did a factory reset, and configured the router manually. I have not seen any radio dropouts, and wired and wireless performance has been the same as on v. 1.0.2.44. I have a 1 Gbps down and 50 Mbps up service from my local cable ISP. Running the speedtest.net app at 6:00 am to my local ISP, I get 650 Mbps down on 5 GHz using my iPhone 8 and a Dell XPS 13 (late 2017); both located 10 ft line-of-sight from the router. Wired download speed is 920 Mbps.

Re: R7800 5Ghz Highly Unstable with Firmware v1.0.2.52

I spoke too soon. Three days after upgrading to v. 1.0.2.52 (with reset and manual configuration), the 5 GHz radio dropped out. The router was still working with wired connections and 2.4 GHz. For a period of five hours, the 5 GHz devices would connect once per hour for less than one minute and then disconnect. I power cycled the router, and things have been fine the last 12 hours.

I re-upgraded to the new firmware, did a factory reset. Had the issue for a while. Restarted everything, realigned some antennas, etc. Once I got it to stop misbehaving, I restored my backed up settings. Didn't re-break it.

 

It has been okay for about 24 hours now. Keeping an eye on it.

From another thread: I managed to keep the router running for 24 hours on this firmware by disabling the automatic firmware update and diagnostic reporting.

Re: R7800 5Ghz Highly Unstable with Firmware v1.0.2.52

This is still definitely an issue.

 

It seems to be happening less frequently with my PC connection, but I am having periodic outages by a Nest device and a Chromecast device, neither of which have changed their position since this firmware update.

 

The 5Ghz drops out and the Nest seems to not recover automatically; the Chromecast falls back to 2.4Ghz which leads to it not being interrupted but instead to a MASSIVE decrease in video quality.

 

I can only recover it by causing the modem to refresh either by restarting it or reconfiguring the 5Ghz channel.

Re: R7800 5Ghz Highly Unstable with Firmware v1.0.2.52

I have been up for 12 days without any problems on v 1.0.2.52, which is  after the power cycle because of the 5GHz problems I reported in the earlier post. The three 5 GHz devices I am monitoring remotely (Nest camera and two laptops) all experienced the same symptoms I described in that post. These three devices are only connected to the 5 GHz SSID, so the laptops did not reconnect to 2.4 GHz, which was still working.

 

For several months when running v. 1.0.2.44, I had trouble with the Nest camera dropping the 5 GHz connection once every week or two, but it usually reconnected within 30 mins. I was not monitoring additional devices connected on 5 GHz at that time, so I am not sure if this problem only affected the Nest camera or all the 5 GHz devices. These problems always seemed to happen when I was at work.
