Hi guys! I have a big problem! I have to use the WAG54G in Italy (ADSL over baseband POTS) but i have bought it in Germany (ADSL over ISDN)! So I wish to know if i can install firmware "Annex A" on my WAG54G-DE (that natively support "Annex B" firmware)!!! So the question is: the difference between WAG54G Annex A and Annex B is only in firmware or even in hardware??? Help me! Thank you very much and Merry Christmas!
