I have a strange problem that I'm hoping to get some help here for. I have an in home network of an Airport Extreme and Airport Express, extending the wireless network via a MOCA network. I am pretty sure the MOCA network is working fine because I have a home office... Mac and Dell computers, and a Tivo Roamio Plus serving multiple Tivo Roamio Minis over the same network. No way I'd have multiple HD streams working at this slow rate. So I downloaded a speediest app to my iPhone 6s Plus and when I run it downstairs while I'm connected to the Airport Extreme, I get pretty 10-20mbps up and down. When I'm upstairs connected to the Airport Express, I'm getting less than 0.5mbps up and down. If I run a speed test from a computer upstairs connected directly to the MOCA network by cat5, I get 60mbps down, 10mbps up, which is closer to what I should be getting. So why am I getting such slow speeds through the Express? And also why am I get about 1/5 the speed I should get from the Extreme via wifi... although that is plenty for my phone. Any ideas? I've tried the usual reboot of everything.
