Yealink T54W: Connecting to Wi-Fi

Phone System Yealink T54W WiFi wireless network setup By Cade · Updated 03/04/26 10:50 PM
The Yealink T54W has built-in dual-band Wi-Fi, allowing it to connect to your network wirelessly instead of using an Ethernet cable. Note: a wired connection is always preferred for better call quality. When to use Wi-Fi: Only use Wi-Fi if running an Ethernet cable to the phone's location is not practical. For best call quality and reliability, wired Ethernet is strongly recommended. Connecting to Wi-Fi: Step 1: Make sure the Wi-Fi antenna is attached The T54W ships with a small Wi-Fi antenna that screws into the back of the phone. If the phone is using Wi-Fi, this must be attached. Step 2: Enable Wi-Fi on the phone Press Menu > Basic > Wi-Fi Toggle Wi-Fi to On if it isn't already. Step 3: Scan for networks With Wi-Fi enabled, the phone automatically scans for nearby networks. Your Wi-Fi network name (SSID) should appear in the list. Select your network and press Connect. Step 4: Enter the Wi-Fi password Use the phone's keypad to enter the Wi-Fi password. - For letters: press the number key multiple times to cycle through letters (like old cell phone texting), or use the 123/ABC toggle softkey to switch between modes - Press OK or Save when done Step 5: Confirm connection The Wi-Fi icon appears at the top of the screen when connected. The phone will register with the phone system over Wi-Fi. If the phone keeps dropping Wi-Fi: - Move it closer to the Wi-Fi access point - Check that the antenna is firmly attached and positioned upright - Consider using a wired connection instead — Wi-Fi dropout directly causes dropped calls - Check if the access point is using a 5GHz-only network — the T54W supports both 2.4GHz and 5GHz Switching back to wired: Plug an Ethernet cable into the phone's PC/LAN port. The phone will prefer wired over Wi-Fi when a cable is connected.
