So Where’s My Low Voltage DC Wall Socket?

That's true. My aging but still well-functioning WRT54G router had its 12V 2A wall wart die on me last year. At the same time, some USB cable had its micro B end accidentally ripped of.

So I thought, why not, opened the router,and lo and behold, the DC circuit is perfectly happy with 5V and 1.2A or so, and converts it down to I believe 3.3V.

So I drilled a hole in the router and soldered the working end of the damaged cable to the power input. Other end is pluggend into the useless USB TV port. Has been working fine ever since. Neither TV nor router runs hot, which I couldn't say about the old wall wart.

In theory, USB should negotiate the required amount of power It turns out the TV manufacturer decided to simply wire the port directly to the internal 5V rail connected to both USB ports, so it should be able to give at least 2x2A.

Yeah, it was probably cheaper to just buy a new router. Got a bit nerd-sniped there I guess ;-) .

Should've let this thing die. Do you actually have devices hooked up to this.. the speeds you're getting and the likely security holes you have (especially if you don't have this properly behind some other device) are concerning me.

Dont worry, there is a decent enough firewall built in to the ISP modem. And my ISP is more than slow enough that the speed of the router doesnt matter much. And when all my computers are off, so are the router, the modem, the TV and all the other stuff.
