My distribution is Fedora 17 Gnome. Every time I reboot/restart my computer I need to run this command as root:
modprobe rt2800usb
How can I make it permanent?

1Hi, thanks for you first question. It would be nice if you could mention which linux distribution you're referring to :)– Bonsi ScottApr 3, 2013 at 19:53

1@BonsiScott The distribution should probably be added to the question text, as well, but the tag says Fedora.– depquidApr 3, 2013 at 19:59

@BonsiScott, your answer could well be useful for others...– vonbrandApr 3, 2013 at 21:57

On any distro using systemd you can automatically load the module via modules-load.d:
create the config file:
/etc/modules-load.d/rt2800usb.confopen it and edit like this (add the module name):
rt2800usbnext time you reboot the module should be automatically loaded
Troubleshooting:
Check if systemd service loaded the module:
systemctl status systemd-modules-load.service
The output should look like this:
systemd-modules-load.service - Load Kernel Modules
Loaded: loaded (/usr/lib/systemd/system/systemd-modules-load.service; static)
Active: active (exited) since Wed, 03 Apr 2013 22:50:57 +0000; 46s ago
Docs: man:systemd-modules-load.service(8)
man:modules-load.d(5)
Process: 260 ExecStart=/usr/lib/systemd/systemd-modules-load (code=exited, status=0/SUCCESS)
The last line contains the PID (process id) and the exit code. status=0/SUCCESS means the module was successfully inserted, confirmed by:
journalctl -b _PID=260
output being:
Apr 03 22:50:57 mxhst systemd-modules-load[260]: Inserted module 'rt2800usb'
In case of failure, systemctl output looks like this:
systemd-modules-load.service - Load Kernel Modules
Loaded: loaded (/usr/lib/systemd/system/systemd-modules-load.service; static)
Active: failed (Result: exit-code) since Wed, 03 Apr 2013 22:50:59 +0000; 43s ago
Docs: man:systemd-modules-load.service(8)
man:modules-load.d(5)
Process: 260 ExecStart=/usr/lib/systemd/systemd-modules-load (code=exited, status=1/FAILURE)
with journalctl -b reporting:
Apr 03 22:50:59 mxhst systemd-modules-load[260]: Failed to find module 'fakert2800usb'
When the exit code is 0/SUCCESS it means your module has been successfully inserted; running
lsmod | grep rt2800
should confirm that:
rt2800usb 26854 0
rt2x00usb 19757 1 rt2800usb
rt2800lib 64762 1 rt2800usb
rt2x00lib 66520 3 rt2x00usb,rt2800lib,rt2800usb
mac80211 578735 3 rt2x00lib,rt2x00usb,rt2800lib
If lsmod output doesn't confirm (despite the service exit code being 0/SUCCESS) it means something removed the module after being loaded by modules-load.service. One possible cause is another *.conf file that blacklisted the module. Look for a line like:
blacklist rt2800usb
in /etc/modprobe.d/*.conf, /usr/lib/modprobe.d/*.conf or /run/modprobe.d/*.conf and comment it out / delete it.

When I reboot, I still have to do the modprbe command. Isn't it listed because the listing is after I ran the modprobe command? Apr 3, 2013 at 22:49

If you need persisting module parameters:
options <module_name> [parameter=value]on/etc/modprobe.d/[filename].conf(access.redhat.com/documentation/en-us/red_hat_enterprise_linux/…) Jul 20, 2020 at 14:14
To load a module on boot, you create a file in /etc/modules-load.d/; this file can have any name, but must end in .conf. In the case of your wifi driver, you could for example create the file /etc/modules-load.d/rt2800.conf.
In the file, add a single line with the name of the module you want to load like so:
rt2800usbThe Arch Wiki page on Kernel modules has more information.
