Due to power brown-outs, surges and outright loss of power at times, we are planning on hooking up the Network Extender along with our DSL modem/wireless router to an uninterruptible power supply (UPS). Low power devices can operate for at least 2-3 hours on a small UPS but at this point I cannot find out how much power the Network Extender will draw. Knowing the power supply specs doesn't tell the story.
Our ADSL modem/router uses approx 12 watts when actively transmitting and receiving data....guessing the Extender would be in the 6-8 watt range.
Anyone had experience with this?
Won't matter much since the extender doesn't work without an active connection to the internet. If the Internet is still coming through the wire, assuming the sub station isn't affected, this might work.
Am aware of that issue, but DSL providers over phone lines - unlike cable - have emergency power that under most circumstances keeps phone lines/DSL active. I have tested my setup with ADSL modem/wireless router, have had the system on UPS battery backup and actively using the modem/router throughout the house. So far has remained on for over 3 hours.
Just trying to estimate what the addition of the Extender will do to the time the devices can remain powered up.
Trial and error I suppose. Given it has to power a GPS module and a broadcasting antenna, I imagine it uses much more than a router, more than a modem, and about the same as a modem/router combo.
Most manufacturers seem to be reluctant to publish power consumption figures, but did discover a couple of websites that have power consumption figures for a variety of more common devices.
As you suggest, trial and error is probably the solution. I will record times with modem/router and then run the same test with the Extender attached and use the cell phone a few times to make the test more realistic. Then we can deduce what the draw might be, but maybe someone out there has actually run tests using proper equip.
Thanks for the responses.
READ the output rating on the network extender's AC Adapter name plate. Multiple volts times amps to get watts and multiple that by .75 for the load in watts it can use. Multiply that by the efficiency factor of the UPS and add to the total load for the battery load. The battery manufacturer has a load chart you can download.
Thanks...that is very useful info. BTW our UPS provided over 4 hours with the Comtrend ADSL modem / router so am confident we'll still have good up-time with the Extender plugged in.
Jdalittle, thank you for the details provided. Are you experiencing difficulties with your Network Extender? Please share details.
