rikytik,
you will need to flash the firmware of the router (wrt54g) with a new firmware from sveasoft (it cost a few $ to subscribe to sveasoft )
if something goes wrong you can always flash it back with the original stock firmware.
I've been running mine at higher voltage for over 7month straigh (no problem so far) i also have a cantenna attached to my lynksy to boost the signal even more.
Now i can effectively get connection always over 70% around my house and withing floors i can even walt down the street and still get reception.
