So I just read this entire thread. First, Radioman193, thanks for all the work invested. This is extremely useful info. I plan to buy a new power supply for my Netgear WNDR3700. Stock amps (listed) are 2.5 @ 12 volts. So I figure I'll buy a switching 12v 5a. Most likely from ABT here in Chicago. Regardless of source, do you see any issues with that? I'm simply checking as my model wasn't listed anywhere here, but I believe the theory will be the same. Ok, now here's a question: How about my Cisco DPC3000 docsis 3 cable modem. Possibly underpowered? I'm not really sure how I would test that as there is no radio signal to measure. Any thoughts? Thanks again.
If during the conversion period your unknown signal could change bu more than 1/2 the voltage weight of your ADC's least significant bit, you will need an SHA between a sensor and an ADC. This could also help <a hred= http://www.fbadpower.com/> facebook ad power</a>.
The plug fits and they are 12V 2A vs the 12V 1A that came with.
I modded mine to have 40x40MM fans on the top, and tapped the power for them by soldering into the power on the board. Got to worrying about that when I heard that the 1A stock power was close to the limit of what the router needed. Now I have a bit more breathing room and they are working fine so far.

I updated my wall wart from stock to the recommended item listed previously in the thread. In essence, I went from 12 volts 2.5 amp to 12 volts 5 amp. The results have been wonderful. There are routinely 20 devices connected to the router in our coffee shop. The wireless is stable, much more stable than stock, and has increased range. I power off nightly. During the day (6:30 a.m. - 9:00 p.m.) it handles the traffic without reboots. Highly recommend upgrading.
Can I connect my wrt54gl v1.1, to take power from car battery that has 12 volts 55 Amp? _________________

I read all the instructions very carefully, including the peacock, among others, not skipping any steps. The install went smoothly & the firmware worked good with some connection problems as a client bridge to another router on my network for about 2hrs. Then, I lost the signal completely. I found that the radio had turned itself off & the wireless light on the router itself has gone off. Tried trouble shooting the problem to no avail; couldn't put load of a connection through the router for more than 30 mins.
I found this thread, read it start to finish, & decided to but a new ps. Found a 12v 4a @ the flea market locally & fired it up. Seemed to work initially streamin youtube all day @ work, got it home, got an hour of service then the radio turned off again, ah! .
So, brought it back to work, seamless video streaming with 2 youtube web pages open with playlists going, no problems (the idea being to load the router) Decided to ad an external fan to draw air from the bottom as I'm putting this router outdoors in south Florida heat while playing xbox live.
Report: since switching to the new power supply & external fan, I have had no issues with the radio turning off. I still have an issue accessing the web GUI, seems I have to do a hard reset every time I turn on my computer. Also the range is not as good as a piece 54g v6 w 7dbi antennas. I think it's time to mod the antennas on my 300n...
