I am a technician with a very large electronics retailer. In October, 2006, I noticed that the 12-volt AC adapters that come with the Linksys WRT54G series routers always put out at least 16 volts and sometimes as much as 22 volts. I have seen this in both 500mA and 1000mA adapters. Linksys tech support responded that these AC adapters are not defective at 16 volts and that the voltage will be regulated by the router. They ignored the problem posed by 22 volt adapters. I believe that over-voltage such as this will lead to premature failure of the router. Given Linksys current fiasco with the WRT54Gv5, I am losing faith in them. Has anyone else observed this problem? What do you think?
