[SOLVED] A wifi PITA

business_kid · 07-09-2022, 08:07 AM

Slackware-15.0, kernel 5.15.27 on a medium weight x86_64 box here.

I'm doing stuff with my connection so I have this script below in place of /etc/rc.d/rc.inet1. It was working fine until I started using this Ralink 5370 wifi dongle

Code:

bash-5.1$ sudo lsusb
Password:  
Bus 001 Device 002: ID 148f:5370 Ralink Technology, Corp. RT5370 Wireless Adapter

A dodgy chip, I know. But it has a kernel driver. Now it fails on bootup, bud if I restart the network, it comes up fine. Why the double-take on startup? Here's the script with the line doing the work in bold:

Code:

#!/bin/sh
# With thanks to montagdude

function print_usage ()
{
  echo "Usage: rc.inet_mine start|stop|restart"
}

function inet_start ()
{
  /sbin/ip address flush dev  wlan1
  /sbin/ip link set wlan1 down
  /sbin/ip link set wlan1 up
#  /sbin/dhcpcd eth1
  /usr/sbin/wpa_supplicant -B   -i wlan1 -c /etc/wpa_supplicant.conf && /sbin/dhcpcd  wlan1 
  /usr/bin/protonvpn connect --cc IE

#  In case I have to set up eth0 some day
#  /sbin/ip address add 192.168.88.9/24 dev wlan0
#  /sbin/ifconfig wlan0 192.168.88.9 netmask 255.255.255.0
#  /sbin/ip route add default via 192.168.88.1
#  arp -s 192.168.88.1 xx:xx:xx:xx:xx:xx(bridge MAC address)
}

function inet_stop ()
{
  /usr/bin/protonvpn d
  /bin/killall wpa_supplicant
  /sbin/dhcpcd -k wlan1
  /sbin/ip link set wlan1 down 
#  In case I have to set up eth0 some day
#  /sbin/ifconfig eth0 down
#  ip route del default via 192.168.88.1
}

if [ $# -lt 1 ]; then
  print_usage
  exit 1
fi

case $1 in
    start)
        inet_start
        ;;
    stop)
        inet_stop
        ;;
    restart)
        inet_stop
        inet_start
        ;;
    *)
        print_usage
        exit 1
        ;;
esac

Thanks for all the many replies, Guys - not!

Solved it. I figured I was asking the dodgy usb wifi chip to do something uncomfortable. This solved it.

Code:

#!/bin/sh
# With thanks to montagdude

function print_usage ()
{
  echo "Usage: rc.inet_mine start|stop|restart"
}

function inet_start ()
{
  /sbin/ip address flush dev  wlan1
#  /sbin/ip link set wlan1 down  ### Commenting out this line fixed it from power up
  /sbin/ip link set wlan1 up
  /usr/sbin/wpa_supplicant -B   -i wlan1 -c /etc/wpa_supplicant.conf && /sbin/dhcpcd  wlan1 
  /usr/bin/protonvpn connect --cc IE …

The restart does a stop (which brings wlan1 down) and then starts it again. The line was redundant, and possibly detrimental.

Mind you, trying to mind read these dodgy usb dongles brings me back to my misspent youth fixing Italian motorbikes. Beautiful to look at, offering bursts of speed inevitably followed by mechanical disaster with a dearth of spares and the most insane problems. I bluffed my way into a mechanic's job fixing real bikes with my hard-won experience.
