First time poster, long time lurker. I have 4 Rokus in total. Three Roku 3's and a new Roku Ultra. Currently my Ultra is running production release 7.2.2. All 4 devices are hardwired to the same gigabit switch which in turn gets 50Mbit FIOS (that 50Mbit up and down).
Using the hidden SpeedTest app (similar to Ooka Speedtest). I typically get ~40Mbit-60Mbit download speeds on all of my Roku 3's depending on the time of day and sever selected. But on the Roku Ultra, over both hardwire and 5Gbit Wifi (WAP is in adjacent room so signal is approx -30 Db) the best the Roku Ultra can do is 14-18Mbit. When I hook up a PC to the Ultra's network cable I get the full 50-60Mbit (Verizon tends to over provision).
Additionally, the Roku Ultra seems to buffer / drop streaming resolution quite a bit more than the 3's. This is exacerbated whenever I try to do 4k (obviously) and especially 4k HDR. But overall the network performance of my Ultra seems to suck using both Ethernet and Wifi. In everyone other way -- interface speed, picture quality (when its not sucking) is better than the 3. I had the ultra hooked up to my 1080p plasma before my 4k arrived, and I was amazed at how much better the picture looked coming from the Ultra at 1080p than from the 3.
Anyway, for those of you that have an Ultra could you try the SpeedTest channel and compare to one of your other Roku models? Just trying to figure out if I got a dud. Or if the OS build isn't fully optimized for the new chipset/etc.
Are there any other speedtest apps or hidden menu tests I should run to benchmark the Ultra's network performance? Maybe the speedtest in the Vudu app (Netflix app might have one as well -- or just connectivity). I'm having a lot of issues holding onto a 4K stream in the Netflix app. Amazon seems to be a bit better. Hoping when OS 7.5 comes out things will improve.
I have a 1 Gig fibre internet connection. My ultra is normally connected by Ethernet and i get a speed of just below the 100 Meg capability of the ethernet adapter. I thought I might improve things if I use the WIFI ac since I felt the speed was being throttled by the ethernet and ac is capable of much higher speeds. I was very surprised to find that the WIFI ac was significantly below the Ethernet speed. I know my WIFI is capable of running at much higher speeds because my Laptop in the same room get speeds of 250 to 300 Meg.
`The WIFI on the ULTRA is certainly not meeting specs.
Its not really a problem for me because there is nothing I am doing on the ROKU that needs more that I am getting on the Ethernet.
I am using a Private channel app to measure speeds.
