I returned home after being gone 3 days. Sometime in that 3 days my Roku Ultra did an upgrade because there is a new background on the Home Screen. Ever since that upgrade, I have had poor connection speeds. From 1-3 Mbps when I test the Roku. I am normally hard wired to an Ethernet switch, but I have also tested 3 different wifi networks I have in my home. a 5ghz, a2.4ghz and a separate wireless connection that I normally use just for security. All show between 1-3 Mbps. I have tested phones and iPads and they are between 300-800 Mbps depending on the network connection.
I have unplugged the Roku and replugged it back in. I have rebooted both routers for the two separate networks.
I am at a loss to fix these connection problems, but they are causing constant buffering which is unacceptable.
