Hi guys,

i would like to make my own 3G router :slight_smile: and was trying to find out if anyone knows which combination has the lowest power consumption?

How about “underclocking” etc. How low can you go? and which RB would you recommend?

RB411UAHR not bad. Power consumption only 3,6W with idle wireless and 3G

Thanks :slight_smile: - your wattage is that based on 12v?

do you know if Lenovo branded Sierra 3G modem works on the ROS?

I have one of them around here somewhere. Or is there a better and less power hungry 3G card?

all those 3G cards are more or less the same. plug it in and see how it works. if it doesn’t - email support and we will see if we can make it work

Did you ever get the Lenovo Sierra Wireless card to work? I have an MC5725 MiniPCIe card that is giving me fits.

this list shows that the card is supported:

Yes sir, I understand that it shows as supported. I have 2 of these MC5725 cards from Lenovo laptops and they are acting very strange. They will only show in system/resources occasionally (actually only once). I have an MC8775 and it works like a charm. Could the problem be with firmware written ONLY for the Lenovo laptop?

Thanks

Some of the 4G cards are POWER HOGS !!
The 300U even has an internal Btty. to aid in transmit power drain…
The Btty charges durring idle time and drains durring transmit..

The 301U I belive does NOT have this issue.. (runs cooler as well)..

Just some handy info..
