Mac Connected to Wi-Fi but No Internet? How to Get Back Online

Your Mac shows full Wi-Fi bars in the menu bar, but Safari spins forever and email won’t load — you’re “connected” but there’s no actual internet.

Why: The Wi-Fi radio link to your router is fine, but something above it is broken — usually a stale or bad IP address from the router’s DHCP server, a wrong date/time (which breaks the security handshake to websites), or a half-corrupt saved network. So you fix the network layer, not the radio.

Fix 1: Renew the DHCP lease (the fastest real fix)

This makes your Mac ask the router for a fresh IP address — the single most common cure for “connected, no internet.”

1. Apple menu > System Settings.
2. Click Network in the sidebar (scroll if needed).
3. Click Wi-Fi (or the active network service), then click Details….
4. Click TCP/IP.
5. Click Renew DHCP Lease, then click OK to confirm.

Try a website. If your IP address field was blank or started with 169.254, this is almost certainly your problem.

Fix 2: Check the date and time

A clock that’s off by even a few minutes breaks the encrypted (HTTPS) handshake, so pages silently fail to load even with a good connection.

1. System Settings > General > Date & Time.
2. Turn on Set time and time zone automatically.
3. If it’s already on but wrong, turn it off, set the correct time manually, then turn it back on.

Fix 3: Restart the Mac and the router

• Restart the Mac (Apple menu > Restart). This automatically renews the internet address and clears transient network state.
• Power-cycle the router/modem: unplug it, wait a couple of minutes, plug it back in, and let it fully start up before testing. If other devices (phone, another laptop) also can’t reach the internet, the problem is the router or your ISP — not the Mac.

Fix 4: Forget the network and rejoin

A corrupt saved network profile causes a Mac to “connect” but never route traffic. Removing and re-adding it rebuilds that profile.

1. System Settings > Wi-Fi.
2. Click Details… next to the network you’re on.
3. Click Forget This Network, then Remove to confirm.
4. Reconnect from the Wi-Fi menu and re-enter the password.

Then run Apple’s built-in diagnostics: press and hold Option while clicking the Wi-Fi icon in the menu bar, choose Open Wireless Diagnostics, and follow the prompts.

FAQ

Other devices work fine, only the Mac doesn’t. Start with Fix 1 (renew DHCP), then Fix 4 (forget and rejoin) — those target Mac-specific network state.

Everything is offline, not just the Mac. That points at the router or ISP. Power-cycle the router (Fix 3) and check for an outage.

My IP starts with 169.254. That’s a “self-assigned” address, meaning DHCP failed — exactly what Fix 1 (renew DHCP lease) addresses; if it persists, power-cycle the router.
