    I was recently given a Linksys WRT54g v5 wireless router. However, the unit's power supply was not included. I also have a v3 and v6 and wondering if I can use their power supplies to operate this v5 hardware.

    Or does the v5 require a different AC adapter? What are the specs of the v5's AC adapter? 9 volts, 12 volts, etc? how about the amps it uses too; 1amp, 1.5amps, 2amps, etc.

    I have a universal AC adapter that I thought I could possibly use, but want to make sure I set it correctly instead of overloading it and possibly burning this v5 up. Any info would be great.

    The v2 through v3 and maybe v4 had adapters that were 12v and 1 amp. Later versions at some point had adapters that were sometimes as low as 500mA, but still 12V.
    The smaller amount of RAM and a smaller board in the later versions must use lower amounts of power.

    Anyway, the voltage is all the same so go ahead and use the older power supplies.
    The higher output is not an issue. The router only pulls what it needs, it won't burn up.
    It's like using a 1000 watt power supply in a computer that pulls 100 watts. Yes, it's not very efficient, but do damage should result.

    You can also check around at thrift stores. I sometimes find generic ones at those types of stores that work fine and cost $1 to $2. Just look for 12V 1 amp and the right connector.
