I have a Netgear wireless router WGR614 v5 with the AC adapter of 120V-60Hz-16W. I've moved to Europe where the electricity is 220V. Can I use an AC adapter of 220V for this wireless router? Thanks a lot...


Yes, make sure you have a new power supply with the right voltage output, enough current (if the new power supply is rated for more current output, it will be OK), and the right plug with the right polarity.

Check your power supply, some will actually work with a wide range of voltage, some actually go from 100-250VAC. 50Hz-60Hz

Will not power on


Hi!
Your description of the problem is somewhat lacking in detail. Here's, however, a few things you can try:
  • Unplug the router and use a bent paperclip or another pointed object to push the reset button on the back of the device. Hold it in for around 30 seconds. Hopefully this will reset the router to the factory settings.
  • If this doesn't work, your power supply might be broken. Look at the voltage, polarity and amperage on the label (located on either the power supply or the device itself). Find a compatible power supply used for something else and plug it in (make sure it's compatible). If the device lights up, good. If not, it's probably an issue with either the power supply or the router. Try to contact the reseller and ask for a replacement or a repair, if it's still covered by warranty.
I hope this helps!

2Wire 1000HG power supply went bad. Need to replace but having trouble finding one. Would like to purchase in a store


Ok there is generally nothing "Special" about mains, wall power supplies, they simply provide DC volts, via a step down transformer, or switchmode technology, now there are ONLY three important things to know and they are, the Voltages, and Amperage, and Power Plug Polarity. You can often find this A: In the manual under Power Supply Specification, B:Or on the Actual power Supply itself, If one looks carefully, there is always on a UL listed power supply, the Output Voltage & Amperage, often Polarity is indicated too. If not, that can be gleaned usually, by looking besides the power input socket, on the actual unit, and, it usually, has a little drawing, with a dot and a 3/4 circle around it, with a + & - showing what goes where. In almost all occasions, though, it is Positive to the CENTER, & Negative to OUTER, (or earth). All you have to do, is get any other power supply that has the SAME Voltage and Current rating, IE: 12 Volts @ 2.5 Amps. Now any 12 Volt supply that gives, the same or MORE than 2.5 Amps will do. You just need to ensure that the Plug is right, often the plugs are different, that too, can be overcome, simply, by cutting off the OLD, plug, and cutting off the NEW plug, and joining, Old, to New end on PSU. Again, usually, Positive is the Center, and the Negative is the Outer. Right go get that supply. eBay or Radio Shack, are good places to start. Also any other "Laptop" power Supply that has same specs as described, will also work. As a matter of point, switchmode is generally "Cleaner" power than a transformer one.. but it is NOT critical.

LOST THE CONNECTING WIRED FOR THE LINKSYS WIRELESS ROUTER WERE CAN I GET A NEW ONE


Which lead do you need? a Network cable or the power or the lead to the filter into the phoneline?

Power - Have a look on ebay and see if somebody has a 2nd hand router going for sale, you'll probably find that buying a new router is cheaper than getting hold of a proper power supply from linksys. The other thing you could try is look next to the socket and see if there is a voltage and polarity symbol in which case you could try run it from a universal adapter with the same settings.

Network cables/Filters/Phone Line leads - Try ebay again or somewhere like http://www.cclonline.com/

In moving I accidentally seem to have lost my power supply. The router shows 12 volts stamped into the back of it, but can anyone tell me the amperage and polarity on the router side? I found an extra...


If t says 12 volt then that is correct.

They are usually 0.75 A (750mA) for these modems

So long as you match those two numbers you will be fine DONT go less on either but you can go higher on the current rating eg you could go to 1.0A

It's indicated on the back of the router for the exact voltage. It could only be 9V or 12V. For the polarity, the inner pin is the positive.

Power supply for westell 327w


Replacing a power supply for the westell 327w is apparently a tricky thing. The official numbers are: Input: AC 100-240V 50/60Hz 21W Output: DC 12V 1000mA You should definitively read the last posting in this thread and see what this guy found out. If you can, try it! A lower voltage does not so any damage, but make sure the polarity on the connector is right. Very interesting! http://www.dslreports.com/forum/r20265443-power-supply-327w-what (Sorry - but fixya does not provide weblinks right now, so you have to copy the whole line and paste it into your browser.) If you have any more questions, just come back here and leave a comment - I'm happy to help.

BEFSR41 power supply?


Both the voltage and the polarity should be printed on the case of the router. The polarity should be right next to where the power plugs in.

The polarity information will look something like this:
--(-(+))--

If you take the router into a local Radio Shack, the clerk will probably be able to tell you which power supply you need.

Power Supply


Have a look an the underside or back of the unit and see if it has a label on it with the voltage and current requirements.

May be something like 12v - 1Amp or similar like 15v - 800mA,
12v - 1200mA etc. These will more than likely be DC as the power supply has the electronics to convert the mains AC to low voltage/current DC.
If you can find them it will be easy to shop around for a power supply to match. It may also show the polarity of the plug that plugs in to the router from the power supply. i.e. outer = Negative (-), center hole =Positive (+).
