Given that other windows users are not having any issues, it seems this might be an issue that’s specific to only some setups…
The specs posted so far are more than enough for Channels, and the disk speeds are plenty as well.
That leaves the network, so it’s worth double checking that you’re using gigabit on both ends. On windows, run this in the command prompt or powershell:
wmic NIC where “NetEnabled=‘true’” get “Name”,“Speed”
For example, I see:
C:\Users\tmm1>wmic NIC where "NetEnabled='true'" get "Name","Speed"
Realtek PCIe GBE Family Controller 1000000000
and then go to http://my.hdhomerun.com, click on your PRIME, click System Status, click System Log, and look for lines like this:
19700101-00:00:03 System: network link 1000f
19700101-00:00:04 System: ip address obtained: 10.0.1.4 / 255.255.255.0
If both ends show gigabit speeds, then consider swapping out the network cable that’s attached to the PRIME. We’ve heard several isolated reports that the ethernet cable that comes with the PRIME can cause issues.
