Router/Version: Netgear R7800
Firmware: 43516
Mode/Status: AP, QoS, DHCP, SMB, FTP
Reset: No
Issues/Errors: Samba crashes. Sometimes it brings down the router.
For me, I can make it happen by:
1. Connect to the Samba share from a Windows10 machine. I use the \\IP\share way in Windows Explorer.
2. Open/close some files.
3. Put the Win10 machine to sleep.

Code:

Wireless devices that change over from broadcom APs disconnect for 3-5 seconds before being associated with the Atheros AP. Swapping from Atheros to Broadcom looks to be seamless.

Router/Version: Netgear R9000
Firmware: DD-WRT v3.0-r43516 std (06/25/20)
Reset?: N
Status: Working (with issues)

two issues I have come across,
First SNMP seems to be working but it is cranking at 25% cpu usage (do not recall this previously occurring on my firmware from dec 2019 can't recall exact version)

2nd issue, the reboot button under the admin tab no longer seems to work, it goes to the reboot screen (with the moving bar) for a few, then just returns to the previous page,, without restarting/rebooting the router/device.
