Question about magicJack Two, 2 Magic Jack Plus Voip Phone With Or Without Computer In Box

Why will my magic jack work plugged into the wall outlet?

All of a sudden my magic jack stopped working while it is plugged into the wall. I had to move it and plug it into the computer. Last year the plug stopped working and you sent me a new plug in free. Is that what is going on now. I tried everything, I unplugged magic jack and the phone from the outlet and plug them into the computer and it is working. However, I want it plugged back into the wall. I am also having problems talking and hearing as it fades in and out all the time. What is going on? Please advise.

This is a common problem with the magicjack. It works when plugged into a USB port on the computer, but not when plugged into an AC wall socket.

Problem:
The separate power converter module has failed.
When the magicjack is plugged into your computer USB port, it is getting power directly from the 5 volt source in the USB port.
In order to use AC wall current to power the magicjack, a power converter module is needed. That module contains a transformer and rectifier that coverts 115V AC into 5V DC. That module is no longer supplying 5V to the magicjack.

Tech section - you can probably skip this part:
The problem is poor quality low ESR electrolytic capacitors in the power module. ESR is Equivalent Series Resistance. A low number is good, high is bad. The ESR of a capacitor is measured with an ESR meter.
The 5V output of the power module measured only 3.5V. I took the power module apart to to trouble shoot. I found two 220uF 10V capacitors that were labelled "Low ESR" (C8 and C9). I measured the ESR of these caps and C8 measured 1.5 Ohms. I replaced the C8 cap and it fixed the problem. 5V output was restored.

Solution:
I do not recommend repairing these power modules. I did it out of curiosity. These modules are very cheap.
Magicjack is aware of the problem and offers a replacement. To contact them, go to www.magicjack.com and go to "support". They will ship you a new power module for about $5.50. Some people have reported that the replacement modules from Magicjack are no better than the originals and have had repeat failures.
Consider getting a power module from another source. There are lots of AC to USB power converter modules available on Ebay for only a few dollars. Search Ebay for "magicjack power adapter".

My magic jack phone stopped ringing and the handset says no line


It sounds like the magic jack is not getting power. Is it plugged into the computer, or a wall outlet? Is the blue light on?

If it is plugged into a computer then unplug the Magic Jack and reboot the computer wait until it reloads and then plug the Magic Jack into a different USB port.

If it is plugged into the wall, Then unplug it for 5 min and then plug it back in.

If it doesn't come up and it is still covered by Magic Jack open up a chat with them at the link here. http://www.magicjack.com/contact.html

My magic jack is not working it is saying no line


The Magic Jack needs power. If it is plugged into your computer or the wall jack, but your unit still doesn't have power, the jack could be defective. Why not unplug the jack from where it is plugged in now, wait for five minutes, and plug it back in. If the device still doesn't work, there is a possibility the jack no longer works.

Magic Jack Plus worked in USB and then Internet on computer stopped working


It's got the wrong gateway setting. Without a gateway (router) to the Internet it can only see local network stuff. I suspect the Magic Jack is still trying to be the gateway but it has no Internet. Stop Magic Jack doing this and it should work.

My magic jack plus will not work and I am wondering if the electrical connector is bad.


Go to the magic jack website and update your adapter. Also try different USB ports and reboot your computer with magic jack connected. If the computer does not recognize the adapter, try disconnectin and reconnecting into different ports. There is a update option on magic jack website and tech support as well.

My computer doesn't recognice the MagicJack


Magic Jack reserves the first empty drive letter number after your hard drive letters. The problem is that it cannot share this drive letter with a flash drive -- in that when Magic Jack is out, some newer flash drives (such as 4GB Kingstone DataTraveller) cannot claim the same letter, and therefore the flash drive does not work. The reverse is true also in some cases too. if you plug in an older flash drive that uses say letter G when G had been previously claimed by Magic Jack, and you click on the Magic Jack icon (tha references G at this time) the Majic Jack stops working on that PC for good. This seems to have come up recently (late June 2009) withthe Magic Jack's new software update. The annoying beeps also have been introduced with this update. Somthing enters digits into Magic Jackphone number dialing buffer that looks like a memory leak from another part of the computer RAM due to poorly written drivers or invalid shared interrupts or DMA regions.

I tried to chat with tech persons so many times and tried many methods but when they say "now unplug and plug in" , then magic jack home page opened on chating window (always) and stopped chating.

and still I'm getting same 'warning' message.
