I just got my GL-E750. Everything works great. I connected the router to my Google Home Wifi through the ethernet port. When I try to do a speed from my Google Home wifi, the test always fails. In some cases, the Google app reports the download and upload speeds are 0.
So I guess the Google Home Wifi cannot access the test server through the router. I check the firewall settings and I am not blocking anything.
Yes, I can run tests on speedtest.net. If I search “speed test” on Google, it pops up a tool and it works as well.
I think the issue is not with my Internet access in general, but what server Google Home is trying to access when it doing the speed test.
My Google Home was able to run the speed test when connecting to other routers, and I don’t think my mobile network provider would block whatever server the Google Home tried to use for speed testing.
