The Hisense U6N runs Google TV and connects to Wi-Fi in the 2.4 and 5 GHz bands, and when it drops the connection, streams slowly or will not join, the cause is usually signal strength, the router's settings or a software state that a restart clears. Begin by finding out whether the TV or the network is at fault. Test another device in the same room on the same Wi-Fi, and run a speed test; if it is slow too, the network is at fault.
The checks in more detail
On the TV, open Settings, Network and internet and check the signal strength: a weak signal means the TV is too far from the router or something blocks it. Move the router closer or use a Wi-Fi extender, and if the TV is within reach of the router, connect an Ethernet cable if it has a port, since wired is the most reliable for streaming. Restart everything: unplug the TV for a minute, and power cycle the router and modem. Forget the network on the TV and join again with the password, since a stale record causes a failed connection.
If the router offers separate names for its bands, join the 5 GHz band for speed when the TV is near and 2.4 GHz for range. A congested channel causes slow streaming, so set the router to a less used channel. Turn off a VPN or a DNS filter on the router as a test, and check the router's MAC filtering or parental controls, which may block the TV. Reserve an address for the TV in the router if it keeps changing. In the TV's advanced settings you may find a setting for Wi-Fi power saving or network standby, which can drop the connection in standby, so turn it off if present.
Update the TV in Settings, System, About, System update, since Wi-Fi fixes arrive through updates. If one app, such as a streaming service, fails while others work, the issue lies with that app: clear its cache in Settings, Apps. A TV that finds no networks at all after a restart may have a failed Wi-Fi module, and this is a repair; contact Hisense with the model number and serial number from the back. As a workaround use a USB Ethernet adapter, if supported, or a streaming stick.
