Linksys 12-volt AC Adapters Put Out 16-22 volts

    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?

    i think somewhere there is a page that tells that the voltage regulator is good from like 3.5 to 25 volts. so this shouldnt pose too much of a problem. but at 3.5 volts the unit draws like 3 amps so its more economical to run it at 16-18 volts.

    Are you measuring that inside the router, while powered up, or with the power connector in hand... When it is plugged in, and powered up, the voltage will be less....

    doesnt matter the voltage can be in that range (3-25Vdc)and still be in the safe operating constraints of the router. the only concern is heat generated by the current at low voltage
