I recently installed a Motorola HPNA 3.1 Adapter (from the Xbox 360 Hardware Kit) to connect a computer to my coax-based HPNA network. I noticed that CRC errors increased dramatically especially when my 2 IPTV receivers are active. I suspect that the HPNA adapter cannot handle multicast flooding lea

Some TV channels (cnn, apl) freeze after about 10 seconds and then I get the "uverse signal has been lost" message. This started in Dec 2017. I have read through all the posts on this topic (going back years) and it seems to be a network problem. Is it related to unicast/multicast mode?Has anyone fo

Hi, I cannot access my home network's Apple iTunes shared media libraries on my wired Windows 10 PC or any of my wireless iOS devices ever since ATT installed this 5031nv router a few weeks ago.

Is this to be expected with ATT Uverse Internet? I had Uverse installed a few days ago:Video quality exceeds the quality of SuddenLink ( Good! )Internet download speeds are *much* slower than SuddenLink's solid 50 Mbit / second ( This is expected )Each active TV receiver reduces Internet download by

I want to limit the impact of IPTV multicasting on network devices that do not require this capability. To that end, I have ordered a Netgear GS105Ev2 Prosafe Plus gigabit ethernet switch. This switch implements IGMP Snooping (V1, V2, & V3) to block multicast to ports which do not require access to
