Modem power adaptor


My modem's power adaptor (the one that was provided with the sales pack)recently bacame faulty. So i purchased a universal adaptor from an electrical store. With the new adaptor, my modem could be switched on. However, only the power indicator lights up. All the other indicator lights are "off". I tried changing the voltage on my adaptor form 12volt(which is the output stated on the initial modem, so i assumed that the new adjustable power adaptor need to be set to the same voltage as well) to 7.5volts. And only one more light appeared(LAN indicator light). But my PC i not able to detect the LAN connection at all. So, i purchased another adaptor and the same happens with the other one as well. Lastly, i connected the first replacement power adapter I purchased, and it worked. I was using the the modem for a short time until the issue started again. When the modem is connected to the adaptor with the output set to 7.5volts(other volts options like 12v, 11v, 3.5v dont work at all) only 2 lights appear to light up-POWER and LAN(but lan cannot be detected by the PC)....wht should i do???

    With any luck, you should buy an original power adapter and quit screwing around with the voltage. Or, just wait and buy a new modem.

    A DC power adapter requires two things, voltage and current. The guess is that you have 12 volts and not anywhere near the 1 amp of current usually required.

On the bottom of the Modem, it usually lists the type of voltage/current ratio, for example, My modem is a 12VDC in, output is .75A Through the modem. Each modem has its own power requirements. Therefore if they dont match, you have the chance of either underpower (which means no use) or overpowering (and killing your modem permanently)

Best suggestion si the same as above by cnavarro, Buy the Right power supply for it, dont just try anything. get the matching one. Otherwise it will be Incident A or Incident B. Neither would work well, and you would end up buying a new modem all together.

I just replaced my 2-wire modum & now my NetgearWG111v3 router goes offline everynight. I have to go thru the "repair" process etc every morning to get back on the internet. I have been told...

To get the IP Address of your Modem you will need to call your Internet Service Provider to get that info, and they can as well assist you in getting that in the Netgear Router.
Or in you windows settings you can check the option in Network and Sharing Center
Click on Home Group and Sharing Options above,
mvincentc_50.jpg Then select Change Advance Sharing Settings... to see the pic/page below mvincentc_51.jpg
Click on the Drop Down of home network to see the exact page posted and select all turn on network discovery so every time you turn your computer ON it will detect you network right away.
I do not think this will be an IP Address issue from the Modem since it should be auto detected by the router.
But if that would be the case then calling your Internet Service Provider will be best so they can provide you the correct IP Address from the modem and help you enter it in the Netgear Router settings.
I hope this helps.
Have a nice day,

From the walljack to the modem, use the gray cable.

Disconnect the yellow cable from the modem to the PC.

Use the black cable from the router to the modem (where the PC was originally connected).

Use the 2 yellow cables for the PC and the laptop going to any of the 4 ports of the router.

Hope this helps!

The router occasionally goes off air. Unplugging it solves the problem. It's about 2 weeks old.

Something you may want to check is the temperature of the power pack.
You may also check the Modem's power pack.
I recently had a similar issue with my router, and it turned out to be the modem power pack over-heating and blinking out the modem for an instant.

ANOTHER COMMON ISSUE: If your modem keeps restarting once the power LED turns solid green, the most likely cause is the power adaptor. Replace the power adaptor and all should be well again.

Your power adaptor might be faulty.  Yes, you can measure to have 6 volts.  But due to faulty electronic component in the power adaptor, the 6 volts will be dropped to a very low level due to "loading effect"  when you connect to the router.
I had the same problem but could not find the original power adaptor.  I replaced it with a 3rd party power adaptor.  You must ensure that the 3rd party power adaptor can provide 6V output with minimum 2000mA (2 amperes) and correct connector size.

Modem connection problems

The DNS failing is because of your Broadband provider. When you purchased their internet, they were supposed to supply you with a modem. If they arent helping you with this, they are scamming you of your money and you need to go with a new provider. The DNS has nothing to do with what you do or what you can do. (Nothing you will do will controll this except for contacting an internet service provider.)
