Whether you’re setting up MAC address filtering on a router, registering a device on a school network, or just trying to figure out if weak Wi-Fi is the reason everything’s slow, both pieces of information are in the same place on a Chromebook.
Quick answer: Click the time in the bottom-right corner, select your Wi-Fi network name, then click Information at the top of the network details box. This screen shows your IP address, IPv6 address, and MAC address (labeled “Wi-Fi”), along with the current connection’s signal strength.
How to Find Your MAC Address
- Click the time in the bottom-right corner of the screen.
- Click your connected Wi-Fi network name.
- At the top of the network details panel, click Information.
- Look for the field labeled Wi-Fi — this is your Chromebook’s MAC address, formatted as six pairs of characters separated by colons (e.g.,
00:1A:2B:3C:4D:5E).
This is the address you’d give to a router’s MAC filtering allowlist, a school’s network registration form, or IT if they need it for device tracking.
How to Check Wi-Fi Signal Strength
- Click the time in the bottom-right corner.
- Look at the Wi-Fi icon — the number of filled bars gives you a quick visual read of signal strength.
- For a more precise reading, click the network name to open the details panel, where signal quality is shown alongside the connection speed.
If you’re troubleshooting a weak connection, walk closer to the router and watch the bars change — a big jump confirms distance or obstruction is the issue rather than a router or ISP problem.
What to Do with This Information
- Weak signal in one part of the house: consider a mesh Wi-Fi system or relocating your router.
- Setting up MAC filtering on your router: add the MAC address exactly as shown, including colons, to your router’s allowlist — a typo here is the most common reason filtering breaks a device’s access.
- Registering for school or work Wi-Fi: some networks require pre-registering your MAC address before you can connect — see our guide on Chromebooks that won’t connect to school or work Wi-Fi if you’re stuck after registering.
- Signal looks fine but speeds are still bad: the bottleneck may be your internet plan or network congestion rather than signal — see our slow Wi-Fi troubleshooting guide.
Still Having Trouble?
- MAC address field is blank or missing: make sure you’re actually connected to a network first — the Information panel only populates fully once you have an active connection.
- Signal shows strong but connection keeps dropping: that points to interference or a router-side issue rather than distance — see our guide on a Chromebook that keeps disconnecting from Wi-Fi.
- Need the MAC address of the Ethernet adapter instead: the same Information panel shows a separate entry when you’re connected via USB-C to Ethernet rather than Wi-Fi.
FAQ
Does my Chromebook’s MAC address ever change?
Some ChromeOS versions use MAC address randomization for new or unfamiliar networks by default, as a privacy feature. If a network requires a fixed, known MAC address, check your Wi-Fi network’s privacy settings for a “Use device MAC” or randomization toggle in the network details.
What’s a good signal strength number?
ChromeOS shows signal as a relative bar indicator rather than a raw dBm number in most versions. As a rule of thumb, if you’re consistently down to one or two bars, you’re too far from the router or something is blocking the signal.
Can I find my MAC address without connecting to Wi-Fi first?
The Wi-Fi MAC address is tied to the network adapter itself, but the details panel that displays it is only accessible through an active or previously connected network entry.
Is my MAC address the same as my IP address?
No. A MAC address is a fixed hardware identifier for your Wi-Fi adapter. An IP address is assigned by the network and can change each time you connect.
