You type the password, it looks right, you hit connect — and the same password prompt pops back up. This authentication loop is different from a network the Chromebook has completely forgotten; here the network is recognized, but the handshake keeps failing.
Quick answer: Forget the network entirely and rejoin it from scratch, typing the password carefully with “show password” enabled. If it still loops, the router’s security type (WPA2 vs. WPA3) or a saved-but-outdated password on the Chromebook’s end is usually the cause.
Why Does the Wi-Fi Password Prompt Keep Coming Back?
- A typo slipping in from autocapitalization or autocorrect-style behavior on the on-screen keyboard, especially with mixed-case passwords
- The router’s Wi-Fi password was changed recently, but the Chromebook is still trying its old saved credentials first
- A mismatch between the router’s security protocol (WPA2, WPA3, or WPA2/WPA3 mixed mode) and how ChromeOS is trying to authenticate
- Corrupted saved network data for that specific network, distinct from a general Wi-Fi adapter problem
- An enterprise or captive-portal network expecting a username and certificate rather than a simple password
If the Chromebook doesn’t just loop but actively deletes the network from its list each time, that’s a related but distinct issue — see Chromebook keeps forgetting saved Wi-Fi networks.
How to Fix a Wi-Fi Password Loop
- Click the network in the Wi-Fi list and select Forget to remove any stale saved credentials for it.
- Reconnect from scratch: select the network again, and when typing the password, click the eye icon to show it in plain text so you can confirm every character before submitting.
- Double-check for characters that look alike, like a capital
Oversus zero, or a lowercaselversus a capitalI, especially with router-generated passwords printed on a sticker. - If the router was recently reset or reconfigured, confirm the current password directly in the router’s admin panel rather than relying on memory or an old sticky note.
- If it’s a WPA3 or WPA2/WPA3 mixed-mode network, try temporarily switching the router to WPA2-only in its Wi-Fi security settings to see if that resolves the loop — some older ChromeOS network profiles handle WPA3 transition modes poorly.
- Restart the Chromebook after forgetting the network, since a stale network daemon state can also cause repeated failures even with a correct password.
Still Looping After Forgetting the Network?
If a clean forget-and-rejoin with a verified password still fails:
- Test the exact same password on a phone or another laptop — if it fails there too, the problem is the router’s password, not the Chromebook
- Check whether the network requires enterprise authentication (username plus certificate) rather than a simple shared password — this is common on school or work Wi-Fi
- Try a full network settings reset to clear any deeper corruption in saved network profiles
- If only this one router causes the loop while others work fine, see Chromebook Wi-Fi problems with specific routers
FAQ
Why does my phone connect fine but my Chromebook keeps looping?
That usually points to a ChromeOS-specific saved network profile issue rather than the password itself — forgetting the network and rejoining almost always fixes it.
Could this be a sign of a hardware Wi-Fi problem?
No, a genuine hardware failure usually means no networks appear at all, not a password prompt that keeps reappearing. See Chromebook Wi-Fi adapter not found if that’s what you’re seeing instead.
Does changing the router’s Wi-Fi security type fix this permanently?
Switching to WPA2-only is a useful test, but if it resolves the loop, you can usually switch back to WPA3 or mixed mode later since most of these issues are one-time saved-profile glitches, not a lasting incompatibility.
