It shouldn't make a difference. The Ultra only has 100Mbit Ethernet, as it's designed for Internet streaming, where even 4K maxes out around 25Mbit.
I guess this is moot by now, but I got a 1GB internet, with a 5E ethernet cable, been a Roku customer for a decade... wireless it was 240+ mbs... after setting it up with the cable went down to 60mbs. So I got a category 6 Ethernet cable, installed that, went down to 30mbs.
Tried it multiple times, on multiple Roku's in different rooms. The 6 cable was 1/2 half the speer of 5e cable (15Mbs), the Wireless was an order of magnitude higher. If anybody else has experienced this or knows why would appreciate comments.
Router: Spectrum 6, service 1GB. Been on Spectrum 2 days ago, got 240mbs on the Roku. Different modem, router, and plan .. wireless fine, ethernet cable with 5e is about 60mbs, with 6cable 30 mbs. Roku's are 4660x.
By the way, my other devices show 700+ mbs, so it's possible to get that from the router. I mean I guess it doesn't matter, I don't have a 4K TV, but I don't know...
