  1. I need to know the maximum possible length of ethernet cable a MOTOROLA SURFBOARD SB5120 can do. I am going to put on a ethernet cable and a wireless router at the end. I need to know how much cable I can use before the signal is to slow or weak. Good Luck Guys!

    not specific to Moto

    From this site:

    Fast Ethernet: 100 baseT (100 mbps)- 100 meters
    10 baseT (10 mbps)- 100 meters
    This is with RJ45 connectors. Since any modem, including Surfboard, relies on ample signal strength, I would think these specs would apply. ( Google can be your friend!)

    Are ya pilfering a signal from the other end of the football field? :angel:

    Don't forget you can use a Switch to push it farther than 100 meters. Acts like a repeater of sorts.

    If you get close to the maximum, you may notice some signal degradation in the form of lower speeds... I think you can do something to shield the cable and squeeze another 10-15m out of it, can't really remember though...

    If you're just trying to get a wireless router close enough to one of your systems to get a solid signal, you could try installing a directional antenna on your wireless router... I did that because I had lots of walls and pipes b/w my computer and the router, and it worked remarkably better.
