How to fix an unstable Wi-Fi connection

Check whether there is wireless interference introduced by other APs. If the Wi-Fi networks around are using the same frequency channel they might be causing the interference as well. Use the proper Wi-Fi tools, such as Wi-Fi Analyzer, to analyze the quality of wireless channels. Put Ultra Stream and your smart phone close to the same AP and compare the Wi-Fi signal strength on both ends. If both ends have weak signal strength, a different channel or AP which provides good connection should be switched to. Otherwise, go to the next step. Change your modem to the 5G (802.11ac) frequency when the Ultra Stream is placed close to the AP. Use the Sub Stream for APP preview.
