Humming Problem

Posts: 6 · Posted: Thu Mar 24, 2005 9:23 pm Post subject: Humming Problem

Setup is as follows:
Linksys cable modem
DLink DI-614+ router
Linksys PAP2 Vonage adapter (less than 24hrs old)

I have no line noise at all when I pickup the phone, like I would think I'd have if there was RF in the office or something.
Once I start dialing a number I get a humming noise on my end, from what I've been told it's not noticeable on the other end.
I've replaced network cables and phone cables
Moved the power supply to the router and the PAP2 to different plugs
Changed phones
Moved lines around on the router
I'm not sure what else to do.
Any help and/or suggestions would be appreciated

sounds like you don't notice the noise because the dialtone is drowning it out. is that possible? is it noisy when there is no conversation while you're on the phone? check this:

Are any of the components near a dimmer-switch? My phone buzzes when I am near the dimmers in my house.
Check the surrounding area... tvs, timers, even a computer, etc., they all could cause buzzing.

That's just too odd. I have a fax machine plugged into Port 2, so shorting it out isn't going to work for me. I did however send a fax on line 2, and placed a test call. Clear as a bell. Once the fax was through howver, the noise came right back.

Will Linksys send out any (better) replacement adapters? or am I going to end up returning the Linksys and finding another adapter
**Edit...never mind...went back and read all 5 pages on the other post. In sum it up...CRAP...no choice but to deal. I've email Linksys to see what canned response I can get Mad

several people have contacted linksys before. there's nothing they will/can do for you. it's a Vonage issue and they will send you another or place you on a list for a "fixed" one...if they ever come out.

Boy you hit the nail on the head with that prediction. Didn't seem to matter that I actually purchased THEIR product...they just passed the buck right back to Vonage

Is it really worth going to Vonage for a replacement until they come up with a real fix?

From Linksys:
Unfortunately at the moment the only solution for the "hum", noise that you're experiencing for the PAP2 is for you to have it replaced through Vonage. This problem has already been raised to our Product Managers and the solution that they've given us is to advice our customers to have the product replaced through Vonage since the PAP2 has already been provisioned by Vonage.

I’ll be glad if this helps. Thank you.

Have you considered the possibility that you may be experiencing ground currents? You may have an ungrounded device in the circuit. If you have been using "ground-busters", 110v AC connectors that eliminate the three prongs and create a two pronged plug for the AC wall current. Do you live in an old building that doesn't use three pronged AC sockets. I think you get my point. Every device must be plugged in in the identical way. Hot to Hot, Neutral to Neutral, ground to ground. Even if one wall socket has been miss wired you may have trouble.

Rotating your AC input won't help if so much as one socket has a problem. You will have to find the source of the bad wiring this will put 60hz through your ground, causing 60hz hums, as well as the possibility of shock between one unit and another.

I considered that, but every plug in my office is shunt grounded (from the ground on the plug down to copper pipe drove into the ground under the house.
I took a LONG CAT5 and moved the adapter to another room...no change. If it was internal to my office, I'd think I'd get the noise when I picked up the phone...I only hear it once I dial a number.
I took a RJ11 and shorted the 2 center pins together like the other posts suggested, and the noise goes away. Pull the plug out and the noise comes right back

some people are offered a replacement and some are offered to be put on a list. not every adaptor has the problem. it's your call.
