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

2 Answers

We have a problem with the majic jack adapter. It does not work when plugged into the wall. It only works when plugged into the computer. This is a new 5 yr warranty majic jack that was working when plugged into the wall and after less than a year, the adapter no longer works. However, we got a new adapter, plugged it into the wall but it only worked 5 - 10 minutes before going dead again.

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. On the magicjack plus there is a blue power light near the word "plus". If that light is not on, then it is not getting power.
The problem is in the seperate magicjack power supply module.
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. It is that power converter module that is failing.
The power converter module has an AC plug on one end and a USB socket on the other end. In order to power the magicjack from the AC current from the wall outlet, you plug the power adapter into the wall socket and the magicjack into the USB socket on the power supply module.
I had the same problem with my magicjack. I measured the 5V output of the power module to be only 3.5V. I took the power module apart to figure out why it failed. I found two 220uF 10V capacitors that were labelled "Low ESR" (C8 and C9). I measured the ESR of these caps and C8 was 1.5 Ohms. I replaced that cap and it fixed the problems. These two caps are circled in red in the photo.
I do not recommend repairing these power modules. I did it out of curiosity. These modules are very cheap. There are lots of AC to USB power converter modules available on Ebay for only a few dollars. Search Ebay for magicjack power adapter.

Your actual MagicJack is causing the adapters to short out, prob. drawing too much current from the wall outlet, that is why your not having the problem when it is hooked up to your computer...cause its regulated there.

Connecting the majic jack go phone to my closed caption phone.

Make sure both jacks are connected together.Some are not. Open all the wall jacks in the home to insure they pass the red and green wires on to the next jack. Connect any that are not, color for color. When all the jacks look like the wiring is OK then try the CC phone again.

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.

I can call out on my Majic Jack Plus but cannot receive calls. The majic Jack is registered and set up on my modem.

This could be failure of the power adapter module.
Is your Magicjack plugged into the wall power thru a power adapter? Try bypassing the power adapter and plugging the magicjack directly into a USB port on your computer. If the magicjack work correctly now, then you have a bad power adapter module.
I had a similar problem. My Magicjack was plugged into a wall socket. First the dial tone became inconsistent, then I could no longer receive calls, then it died completely.
I plugged the MJ into a USB socket on my computer, and it then worked normally.
If you have a failing power adatper, it will continue to deteriorate, and it will eventually fail completely. The blue power on the magicjack will not come on when it is plugged into the power adapter, but it will illuminate when plugged into the USB socket on the computer.
Note: the computer must be on to power the magicjack thru the USB port.

Magicjack is aware of the problem and offers a replacement power adapter module. To contact them, go to 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".

mcdevito75 here, You cannot access the internet and make a phone call also unless you have DSL. You can get an adapter for your phone line. This adapter will go into your phone jack and be able to hook up 2 phone lines, 1 to your computer internet and 1 to your phone, however you"ll have to dis-connect from the internet to recieve or make a call, and if your on the phone you can"t get the internet. This phone jack adapter is available in Radio shack or even some dollar stores. You can of course make a phone call with a cell phone while connected to the internet.
