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 getting the RZ608 driver straight from mediatek?

The issue seems to be the Netgear firmware.  I upgraded to the latest V1.0.4.84_10.1.84 firmware and turned on IPV6 and set it to "6To4 Tunnel" for the DNS issue.  However, the DNS issue remained unsolved.  I tried reverting back to V1.0.4.68_10.1.75 the DNS issue was still there!  Tried IPV6 to Disabled and still the issue remained.  By now I was on thin ice with wife and kid!!!  Between the unsolved DNS issue and the current issue, I was done with the Netgear firmware.

Did some quick research and chose OpenWrt as the firmware replacement.  Used their wiki https://openwrt.org/toh/netgear/r8000 to install the router and https://openwrt.org/docs/guide-quick-start/basic_wifi to setup the Wifi.

No DNS issue (obviously) and the large file copy went through with out an issue.

 

To recap

Issue: The 5G radio stops working when copying large number of files with PC using rz608 wifi 6e card (rebranded MediaTek MT7921K).

Root Cause: Netgear Firmware (both V1.0.4.68_10.1.75 and the latest V1.0.4.84_10.1.84) has issue handing large file copy

Solution: Use OpoenWrt firmware

 

Hope this helps others.

Thanks

    I put my R8000 FW v.84 online behind my CM1200 modem. 

    Connected a RAXE500 router wirelessly (wireless bridge) to the R8000 on a 5Ghz radio. Smart Connect disabled so I can ensure I'm connecting on a 5Ghz radio. 1300Mpbs connection rate seen on the RAXE500 connection status. 

    Wired PC connected to RAXE500 on 2.5Gb LAN port with 2.5Gb ethernet adapter on PC. 

     

    Sent a 4Gb file up to a drop box with no problems or disconnections being seen. 

    Sent a 32Gb file up to a drop box with no problems or disconnections being seen.
