Hi Bought a Linksys WRT54G yesterday. A friend told me to try the dd-wrt.v22.prefinal5. I tried to upgrad the unit but it said wrong file. S/N CDFB0EA71539 I didn't find a s/n like this in the list. Is it possible that my WRT54G is a new V6? thx for help PS: I tried the newest firmware from linksys too. Same error.
