Roku's Wi-Fi article gives the sequence and a code table. Check your Wi-Fi and password: make sure you are on the right network with the right password. Test with another device: if a phone or laptop cannot use the network, contact your internet provider. Restart the Roku: Settings, System, Power, System restart, or unplug it for ten seconds. Restart the router and modem: unplug both, or the single gateway, wait ten seconds and plug them back in.
The checks in more detail
The code table: wrong password is 14.40, 14.41, 14 or 014, so retype it; a weak Wi-Fi signal is 14.20, 14.62, 14.64, 016 or 017, so move the Roku closer and restart the router and Roku; Ethernet cable issues are 012 or 013, so unplug the cable for ten seconds, try another cable or use Wi-Fi; slow internet is 018, so move closer and restart the modem and router; cannot connect to the internet is 009, 14, 14.10, 14.11, 14.30, 14.50, 14.62 or 14.64; and cannot update is 003.
Common messages: Unable to connect to wireless network during setup, follow the on-screen suggestions; Checking wireless connection with a red X means the connection failed, so restart the player or TV and modem and router; Not connected to the Internet means an app lost connection. A Roku needs a remote to join Wi-Fi. For advanced issues, Roku's networking article covers settings. Roku says to contact your internet provider if these steps do not help.
Run a speed test from a phone standing beside the Roku. If the phone is fast and the Roku is slow, the Roku's own placement or antenna is the cause, and Ethernet, where the model has a port, is the reliable fix. Note the error code shown on screen and the time it happened. Codes map to specific causes, and a pattern by time of day points at router load or a neighbor's interference.
