A few general things that may or may not apply here:Ive also used my iPhone 11. Either fast.com or speedtest.net. Still getting around 90-95. I’ll probably reach out to the install company and see if they have any ideas. Thanks for all the info.
You'd have to check to make sure the correct protocol is being used. Some routers and/or devices will default to a lower bandwidth setting like n, which provides less throughput but greater range than ac. You might have to manually override the settings.
Another factor is that some routers might apply the protocol for the lowest bandwidth device connected to it across the board. So if you have an older b device actively connected, your modern n/ac iphone might get a downgraded connection. At least this used to be an issue, not sure about now.
