NOTE: The current modems are new Engineering Samples with the newer Firmware Revisions: EM20GRUR01A08M4G and/or EM20GRUR01A07M4G.  Production versions DO NOT exist.  They may or may not be compatible with the some version builds of WiFiX/GoldenOrb/ROOter without first downgrading the firmware to EM20GRAR01A06M4G per THIS tutorial. 

UPDATE:  Our newest WiFiX firmware supports all EM20-G firmware revisions.


NOT RECOMMENDED for use with the M2M NEXG H721 due to this router’s high rate of burn out failures.  We will warranty NO modems that are used in the M2M NEXG H721 router. 

IMPORTANT:  Exercise extreme caution while installing MHF4 connectors to the modem antenna ports.  The ports are delicate and easily damaged.  Assure that the MHF4 connector is perfectly centered, level and aligned with the modem port.  The MFH4 connector will then snap into place using minimum pressure. Do not apply excessive force.  A damaged modem connector port is not covered under warranty.

It is strongly recommended to invest in a quality power strip surge protector (i.e., APC, Belkin,…) to use behind a router and/or electronic equipment.  This will help protect against Transients (momentary spikes/surges in voltage or current) that can be detrimental to expensive equipment.  Transient damage to modems are not covered under warranty.  Protect your equipment!

    This modem is the cats meow when it comes to speed. This modem blew away my old MC7455. My speeds have increased by 50% from my old modem to the EM20-G. If you are looking for the fastest modem, this is the one. Thanks Jim for providing really great prices and super fast shipping!

    Upgraded from EC25-AF to EM20-G. Best decision of my life. Speed went from 10 Mbps to 70+ Mbps with MIMO and AC. Please note that this does not support band 71 for T-mo

  3. 5 out of 5


    Upgraded with this little guy from a Mofi4500SIM4 Model. Much more band for you dollar in this package! Combine this with the WG3526 router from here and you got yourself a MACHINE! It supports 4×4 mimo antenna configurations for more speed and a crap ton of Carrier Aggregation! If your tower is capable, this modem is the BEST option for any build I have ever seen!
