Actiontec MI424WR causing ham radio interference

I wonder if any other amateur radio operator has experience interference from the wireless/modem/router?

For me the problem is on 147.21MHz (our local repeater output). On my station rig with the antenna on the roof top, I can

squelch out the interference with the squelch at maximum. On my HTs (mutiple) I'm unable to squelch the interference until I'm about 50 feet away from the house.

I have called Verizon Fios tech support and they cannot find any other reports of this type interference. If I can find a friend using FiOS with the Actiontec modem, I'll see what happens at their location with an HT, but so far they all have a different modem.

lol, i heard this was possible before, but never encountered anyone that had it happen to them lol

wifi is pretty simple radio technology uses a similar bandwidth as some other simple radio technologies ....

try just changing the channel on the router

That doesn't seem to be the problem. Wireless portion is turned off so there should be no sending/receiving on channel 11 or any other channel.

Are you sure the signal source is the router? Since the router is intended for residential use, I believe it needs to be a class 'B' device, so it isn't permitted to radiated much energy in licensed spectrum.

So the first priority is to find out which device is radiating the energy, if it is the Actiontec, it is time to contact Actiontec and the FCC.

There are many other devices that could be radiating, and the first priority is to figure out which one. Display devices are notorious, and 141.7 could be the pixel rate on a display device.

Once you are sure where it is coming from, it will be much easier to figure out what to do about it.

Yep, when the power to the Actiontec is 'off' the interference is gone. Also 'direction finding antenna' also physically points to the modem. I suspect some switching circuit internal to the modem is the problem.
