For example, each time you visit a web page on the Internet, you download the information on the page, including any pictures, to your computer. If not, check the documentation that came with your router, or see if it's printed on a label somewhere on the hardware itself. If the modem for some reason is incapable of upstream DTU, then (depending upon chipset) it is possible to update the firmware so that it can simply acknowledge safe receipt of data (RRC) in the downstream direction only. While IP Passthrough essentially turns an Opengear into a modem-to-Ethernet half bridge, some specific layer 4 services (HTTP/HTTPS/SSH) may still be terminated at the Opengear. Within the DOCSIS segment, time-division multiple access (TDMA) is used to separate downstream and upstream - in contrast to television broadcasting, a network connection needs to be bi-directional. Any problems on the downstream digital channel of HFC Network 18 can cause errors in the data received by the modem resulting in packets to be lost.

Arris said it is working with Intel on a firmware fix for the SURFboard SB6190, a DOCSIS 3. On a DOCSIS3 cable modem system, the CMTS sends a packet called an MDD (Mac Domain Descriptor) that tells the modem specific details about the cable plant, they determine whether the cable modem attempts to boot up in IPv6 or IPv4 mode. Obviously it doesn't seem to be affecting my service but I'm curious none the less. A power cycle on the modem got the sync speed back to 110/110 in both directions and everything is behaving normally now. A flashing or blinking us/ds means that the modem cannot connect or establish a connection due to a missing signal. Upstream I only have a cable modem, so the IP address of Mac #1 is my ISP-provided external IP. 0 technology allows TC7650 to deliver speeds 24x faster than DOCSIS 2. Reducing the allowed downstream throughput per cable modem – By reducing the maximum downstream transmit rate in the appropriate DOCSIS configuration files, cable modem users are not able to download at as high a rate in the downstream direction and downstream congestion is relieved. TRENDnet’s AC750 Wireless VDSL2/ADSL2+ Modem Router, model TEW-816DRM, offers a combination high performance modem for internet access and a powerful wireless AC750 router.
