Connection Dropped on 1.13

[hillbilly]

Hi,
I've just flashed a Netgear WNDR3800 v5 (128Mb RAM) with 1.13. I have a Linux Laptop connected to the Ethernet port on the router, I was copying a large file to a Windows 10 PC using SCP from the Linux Laptop. PC is connected via WiFi. Half a minute into the copy, I noticed:

1. Other computers are not able to access the internet
2. The router became unresponsive, such that it wouldn't respond to ping or the Web Admin page.
3. The file copy (scp) continued, it was running at around 10MB/s

I rebooted the router and repeated the copy, same thing happened again.

I'm sure I've done this on version 1.12 on a TP-Link Archer C7 without any problem. Any ideas?
Thanks.

Once the scp copy completes, the router comes back to live immediately.

You mean a wndr3700?
Are you attempting to use WPA3 encryption for wifi?

[hillbilly]

Yes you are right, it's the WNDR3700 v5 (mt7621-wndr3700v5).
WiFi is set to WPA2 PSK, not using WPA3.
