Home Wi-Fi doesn't work on laptop, but home Wi-Fi works on other devices. Home Ethernet works on laptop, and laptop seems to work on other public Wi-Fi networks (Windows 11, Lenovo Legion)

This is such a dumb problem. I have a Lenovo Legion (16IRX9H) laptop with Windows 11 Home (version 24H2).

I work from home with this laptop and use ethernet 99% of the time. The ethernet works great.

I recently noticed my Wi-Fi wasn't working when I changed rooms. I observed the following:

• I see my usual home wireless networks available (same network, but 2.4ghz and 5ghz versions)

• When I try to connect to them, it thinks for 30 seconds and says "No internet, secured"

• The Windows troubleshooter says "Can't connect to the internet because your current IP address is for a local network only" - the remaining troubleshooting steps never work (see below)

• My phone and other devices in the home connect to these WiFi networks just fine

• I was visiting family in late June and used their wireless network without a problem. I experimented today and was able to connect to McDonald's WiFi, no problem

I have done a lot of reading and found many reddit threads with similar or adjacent problems. Here is what I have tried so far:

• Restarted Wi-Fi adapter
• Restarted modem and router
• Ran diagnostics on my router - all was fine except "DNS #1" was "Fail," but it didn't suggest any fix
• "Forgot" wireless networks and re-added them
• Changed DNS from Automatic to CloudFlare (1.1.1.1 / 1.0.0.1) and Google (8.8.8.8 / 8.8.4.4) DNS services (neither worked)
• Switched from a public network to a private network and back
• Went to command line (as administrator) and did a bunch of things suggested by redditors (netsh winsock reset; flush dns, registerdns, release, renew)
• Checked for Wi-Fi adapter (Intel® Wi-Fi 6E AX211) driver update (already up to date) but reinstalled driver anyway from Intel website
• Disabled Windows firewall
• Checked for updates: there were no windows updates available (last update was 7/13), and Lenovo had a BIOS update so I updated that (didn't help, but I didn't expect it to)
• Virus scan including Windows Defender offline scan (no problems found)

I've seen other posts express concern about the NIC being bad, but I got onto McDonald's Wi-Fi today (as a test) and streamed a long youtube video. (I don't tether to my phone and I had mobile data off on my phone) - it was definitely Wi-Fi

Let me know if I can provide any other information.
