Problems such as occassional lose of browsing, streaming services, and/or your MMS dropping off line, may be the result of the DHCP or DNS settings on your MMS.
We recommend using a static IP address on your MMS. This may either be configured as
(1) setting a static IP address on the MMS configuration page
(2) setting the MMS Configuration to DHCP with an IP reservation on the network router.
In either case, we recommend the use of Google's DNS servers
