Wireless Router 

As noted before, the MT8733 has a unique Wireless Network Name/SSID 
and Wireless Security Key/Password printed on the MT8733’s bottom label.  
Set up your wireless devices to work with this SSID and security key, or with 
the SSID and security key you specified, if you changed them. 

Note that wireless performance depends on a number of factors.  Please keep 
these things in mind: 

 

Where possible, put the MT8733 in a central place so that it’s not too far 
away from your wireless devices that need Internet access.  

 

Try to avoid interference from Bluetooth headsets and stereos, microwave 
ovens, WiFi-capable printers, and 2.4 GHz cordless phones and base stations. 
Try not to put the MT8733 close to these interfering devices.    

 

Sometimes it helps to change the MT8733 wireless channel frequency to 
reduce interference with neighbors’ wireless networks. This is discussed in 
the Troubleshooting section of this Quick Start.  

 

Wireless range can be limited by a variety of issues, including weak wireless 
clients and challenging building configurations. Sometimes devices with a 
weak wireless signal will connect to the MT8733, and often those devices can 
slow down your network’s WiFi. If you need greater wireless range far away 
from your MT8733, you could add a Range Extender. For more information, 
please see 

www.motorolanetwork.com/extenders

 

If you have coaxial cable running near your router and a distant wireless 
access point, HDTV, or other device, MoCA is often a good way to connect 
the router to the device. MoCA can share the same cable used for cable TV or 
cable Internet. With the Motorola MM1000 MoCA Adapter, speeds are up to 
1,000 Mbps. Please see

Telephone Adapter 

The MT8733 includes two telephone ports that support standard (land line) 
telephones and other devices. The MT8733 is designed to work with Comcast 
Xfinity voice service only.  

To use the telephone ports, first make sure you have subscribed to Xfinity 
voice service. This service may be provisioned to support either one line, 
Tel1, or both Tel1 and Tel2.
