I faced problem on fedora server while it is connected to internet via wifi.
I have Fedora Server 31 (kernels: (5.5.8-200.fc31.x86_64(primary)),(5.3.7-301.fc31.x86_64))
Server has wifi adapter TP-Link with “Qualcomm Atheros AR9227” chip on the board.
The problem is, that after some time on ping i can see “no buffer space available” message.
To solve that problem I can simply “REBOOT” adapter via nmcli
nmcli radio wifi off;sleep 1;nmcli radio wifi on
But this thing happened again while using ssh (via sslh)(or even via internal vpn)…
On internet i founded that this is a problem with wifi drivers, but on ubuntu this can be solved with installing (ath9k)… which is already installed with fedora…
Can anyone help me to solve that problem?
