After I manually edit the:

vi /etc/config/wireless

file, what should I do to apply the modifications? Until this day I rebooted the router, but aren't there any better solutions? (and no, www is disabled on the router)

From the Unified Configuration Interface:

No need to reboot

After changing the port uhttpd listens on from 80 to 8080 in the file /etc/config/uhttpd, save it. Then do

uci commit uhttpd

And then a

/etc/init.d/uhttpd restart

Done. No reboot needed.

This is for httpd, but I can't figure out the wireless as was in the Q – gasko peter Jan 25 '13 at 10:05

There is special wifi command. There is a lot of references but I didn't find any standalone manual for it.

Usage: /sbin/wifi [down|detect|reload|status]

To apply wireless settings use

wifi reload

It is a good practice to reboot the router so that new wireless changes can be applied to the wireless portion of the router. Alternatively, you can use:

wifi down
wifi up
