R7900 5G-2 Band Drops Speed from 200mbps to 2mbps

Hi. Over the past week I've noticed the 5G-2 band on my R7900 will drastically drop speed for no noticeable reason. Last week I change the broadcast channel from 149 to 161, which I thought was the source of the issue. Router did a soft reset after applying new channel setting and speeds went back to normal. Fast forward a week and the same drop in speed happened again. This time I just did a soft reset and left the channel the same. Speed went right back to normal after reset. 2.4G and 5G-1 bands are never impacted when the 5G-2 band is having these issues.

I've tested the speeds with multiple devices ~1 foot away from the router. I'm using latest firmware (V1.0.1.4_10.0.12).

Any suggestions to fix this issue?

Thanks in advance.

I found the issue and have got a work around for now. I posted the solution to this new thread for anyone who runs into the issue. I believe it is a firmware issue but it can be mitigated until they fix it. Here is the link to the other thread... https://community.netgear.com/t5/Nighthawk-WiFi-Routers/Do-NOT-use-Dynamic-QoS-on-Nighthawk-R7900/td-p/1251916

I wasted enough time on this. Support can read my notes. Unless they want to pay me for my services.

Exactly one week since posting this and the problem has happened again, this time on both 5G channels. The 2.4G channel is fine throughout the issues. Any help would be appreciated.

Hi harryballzanya,

1. How many devices are affected?

2. Have you tried to reset the router to factory default? If not yet, please press the reset button at the back of the router until the power light turns amber. Manually reconfigure the router after the reset.

  Thanks for the reply and the help! ALL devices connected to the 5G bands are affected. I will attempted to reset to factory and reconfigure during low usage period and will report back. Thank you!
