Re: Go ports are crashing wireless (AX201)

Hello Bjoern,

I subscribed PR 279717, and I got this problem of fetching from go ports. I
do some rtorrent tests (sometimes for several days) with 100GB downloads
and conection is steady.

As I remenber I think I always connect with vht/80:

```
wlan0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
        options=0
        ether xxxxxxxxxxxxxxxx
        inet 192.168.1.188 netmask 0xffffff00 broadcast 192.168.1.255
        groups: wlan
        ssid OpenWrt-5 channel 40 (5200 MHz 11a vht/80-) bssid

        status: associated

```

Thanks,
