R8000 5G modem drops connection when large files are copied
Hi I have R8000 Triband router that has been working very well for years (except of the DNS issus for which I had to downgrade). I just bought a new Minisform UM560 which has a rz608 wifi 6e card (...
have you tried copying the large files between other devices?
6E is pretty new and maybe there's an issue with that specific card/device.
I should have mentioned it in my original post. I have copied the same set of large files between the same NUC and an older laptop using the exact same 5g Modem and had no issues.
Thanks

If it only happens when connected to the new device, it kind of points at that new device as the issue.
Got a spare usb wifi adapter around you could try it with on that device to see if its related to the card or the windows install?
The issue is that the R8000's 5G radio becomes completely inoperable. i.e. all my other devices connected via 5G lose internet connectivity. Devices connected via 2.4G still works fine. Regardless of any new device, I would expect the Router to protect itself from going down.
Thanks
Rockmeister64Long post... I wanted to provide the latest update.
Issue: The 5G radio stops working when copying large number of files with PC using rz608 wifi 6e card (rebranded MediaTek MT7921K).Router Hardware: R8000
Copying files from: An Intel NUC PC that has a direct hardwired Ethernet connection to the router
Copying files To: Minisform UM560 which has a rz608 wifi 6e card (rebranded MediaTek MT7921K)
Details: The files starts copying and I see a speed go up to 50MBps and then within seconds the R8000 5G radio stops. All other devices connected via either of the 2 5G radio lose connectivity. The only fix is to reboot the modem
First Attempt with Firmware: V1.0.4.68_10.1.75
Next Attempt: upgraded to the latest stock Netgear firmware V1.0.4.84_10.1.84 and turned on IPV6 set it to "6To4 Tunnel" for the DNS issue. Tried copying the same set of files and had the same issue of the 5G radio stop responding with in seconds. There was nothing written to the log. I cleared the log before starting the copy, the only entry was
[DHCP IP: (192.168.1.XX)] to MAC address XX:XX:XX:XX:XX:XX, Thursday, Aug 04,2022 00:16:24
Third Attempt: Took a Google Nest router from a friend and did a factory reset and went through and setup it all up from scratch. Tried copying the same set of files and was successful. Throughput around 30MBps
I believe there is an issue on the Netgear R8000 handing PCs with rz608 wifi 6e card (rebranded MediaTek MT7921K).
I have been on stock firmware for the past 6 years and the Netgear R8000 hardware has been rock solid. I may have to venture into open source firmware as a last ditch attempt to keep it going. I am not into any fancy QOS, VPN or other features. Just need stable WiFi and good throughput. Any pointers on which open source firmware to should I try? DD-WRT, Fresh Tomato or OpenWRT???If you are still reading! Thanks a bunch!!!
