A recent update broke Wi-Fi #
This can happen with some operating system updates. Windows 10 updates in mid-2020 had bugs that stopped some users from connecting to their Wi-Fi networks or even seeing Wi-Fi connections at all. Similar updates to iOS, Android, and other platforms have also created bugs in the past that disrupt Wi-Fi connections.
When something like this happens, it’s best to wait for a patch that fixes the problem. In the meantime, remove the update and roll back your system to an earlier version to help get your online connectivity back.
While routers can last for years without needing a replacement, keep in mind that some problems can develop with age — a router may start lacking support for new device updates and similar issues that prevent it from working properly (as seen when Apple discontinued the AirPort Extreme, for example). That’s a sign that it’s time to look for a new router.
