installed Tahoe 26.0.1 on a Mac Mini M1 from 26.0, now it fails to connect to the internet via wifi. Rebooted router, re-entered wifi password. The only change was new MacOS version.

In WiFi try using the "Forget This Network". Reboot and set your WiFi back up.
Did you reboot your Mac? I have not seen this issue on my Mac Mini m4. Did you check your network setting to be sure you are on the correct network?
Hi, I've the same issue since I upgrade macOS 26.0.1 on my MacBook Pro M4 Pro. my Wifi is disconnected every few minutes and especially when I use a lot the bandwidth for activity like big files download.
it is definitively an issue due to this version of macOS.
please Apple, fix it ASAP !
I tried many actions including rebooting the router, rebooting my Mac, forgetting this SSID and reconnect, try another Wifi and there is definitively an issue !
It appears only after the update 26.0.1 and worked perfectly before (26.0.0 and before)
@apple please fix it.
Happy to help identifying the root cause by proving more info...
Yes, I rebooted the computer, forgot the network, made sure that I’m on the correct network.
What version of LS are you using?
