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:
/etc/systemd/system/network@wlan0.service
With content:
[Unit]
Description=Network Connectivity (%i)
Wants=network.target
Before=network.target
BindsTo=sys-subsystem-net-devices-%i.device
After=sys-subsystem-net-devices-%i.device
[Service]
Type=oneshot
RemainAfterExit=yes
EnvironmentFile=/etc/conf.d/network
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
[Install]
WantedBy=multi-user.target
and
/etc/conf.d/network
with content:
interface=wlan0
address=192.168.0.102
netmask=24
broadcast=192.168.0.255
gateway=192.168.0.1
Your IP / gateway may vary. You will also have to edit file:
/etc/resolv.conf
So it contains DNS servers that You’re using. Example:
nameserver 192.168.0.1
and then enable service:
systemctl enable network@wlan0.service
and reboot.
After the reboot my card was connected.
[root@wishthinkpad andrzejl]# journalctl -b | grep wlan0

Thanks again Boohbah I wouldn’t be able to solve that without You.
Hopefully someone else can use it in the future.
Regards.

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.
