# **Section 1 — Fixing Wireless Connection Issues**
Many Epson Workforce 645 printers connect via Wi-Fi. Wireless problems are a huge reason printers go offline.
## **Step 1: Reconnect Wi-Fi**
1. On the Epson Workforce 645 control panel, select **Home > Wi-Fi Setup**.
2. Choose your Wi-Fi network.
3. Enter your Wi-Fi password.
4. Wait for confirmation that the printer is connected.
## **Step 2: Move the Printer Closer to Router**
If the signal is weak, the printer may show offline even when connected.
### Tip:
Keep the printer within 3–5 meters (~10–15 feet) of the router for best signal strength.
## **Step 3: Restart Your Router**
1. Unplug your router from power.
2. Wait 30 seconds.
3. Plug it back in and wait until the lights stabilize.
## **Step 4: Check Your Network Name (SSID)**
Ensure your Wi-Fi network hasn’t changed after a router reset or update.
## **Step 5: Check for IP Address Conflicts**
Sometimes, routers assign new IP addresses. If the printer’s IP changed, the computer may still try to send print jobs to the old one.
### How to Fix:
1. On your printer, print a **Network Configuration Page**.
2. On your computer, go to **Devices and Printers**.
3. Right-click the Epson printer > **Printer Properties**.
