[UPDATED] Bloody RT73 USB dongle wouldn’t connect at boot time.

Hi all.

I own this dongle:

Bus 001 Device 003: ID 148f:2573 Ralink Technology, Corp. RT2501/RT2573 Wireless Adapter

It’s plugged in to my “stationary” IBM Thinkpad 600E laptop. Only one network. Static IP. It would connect to internet when system was booted fully but not during boot time.

BIG thanks to Boohbah he sorted me out when I was loosing all hope…

To solve this issue I had to do this (as root):

Create two files:


With content:

Description=Network Connectivity (%i)

ExecStart=/sbin/ip link set dev ${interface} up
ExecStart=/usr/sbin/wpa_supplicant -B -i ${interface} -c /etc/wpa_supplicant.conf
ExecStart=/sbin/ip addr add ${address}/${netmask} broadcast ${broadcast} dev ${interface}
ExecStart=/sbin/ip route add default via ${gateway}
ExecStart=/usr/sbin/iwconfig ${interface} power off
ExecStart=/usr/sbin/iwconfig ${interface} rate 1M fixed
ExecStop=/sbin/ip addr flush dev ${interface}
ExecStop=/sbin/ip link set dev ${interface} down




with content:


Your IP / gateway may vary. You will also have to edit file:


So it contains DNS servers that You’re using. Example:


and then enable service:

systemctl enable network@wlan0.service

and reboot.

After the reboot my card was connected.

Thanks again Boohbah I wouldn’t be able to solve that without You.

Hopefully someone else can use it in the future.



EDIT 01: Adding pci=noacpi as a kernel parameter seems to make this temperamental USB device to behave slightly better…
EDIT 02: Power management needs to be disabled and the rate must be brought down to 1M otherwise card disconnects AND looses pings.
