Bluetooth not working in MacBook air

The Bluetooth in Macbook air 2020 doesn't switch on after waking up. This occurs after I updated to Big Sur. It only resolves after restarting and then again happens after waking it up from sleep. Too frustating

MacBook Air 13″, macOS 11.5

Ventura Bluetooth issues. Why is Apple dragging its feet when addressing the Bluetooth issues created with the Ventura OS 13.0 update? It is impossible to connect my keyboard to my Macbook Pro since the update and all of my mice have a terrible lag as if the buffers get full and then empty out. I can never tell where the pointer will be at any given time because it seldom follows my mouse. The keyboard and mice work fine on all other Bluetooth enabled devices, but NOT on the one device I have with Ventura. (And, yes, I have done all the troubleshooting. Nothing makes it work properly for more than a few minutes.) It is sloppy and anti-user to let this bug continue! I left PC's to get away from this kind of shoddy workmanship!

Wifi interface is missing after updating mac OS Monterey Hello all, Surprisingly, I am facing a wifi/Bluetooth interface issue in my MacBook Pro in early 2015 13" inch after updating the system software. The wifi symbol is showing with a '!' mark. Bluetooth is working fine for now. But I can't see any wifi/Bluetooth interfaces to add, minus, or edit in the list. right now I am using the internet via LAN cable. I have found similar articles but with a different OS and MacBook device also. I would like to know the technical aspects behind this issue if possible. I have tried soft reset also. If anybody has any idea on this, please do suggest to resolve the issue. Any suggestion is appreciated. Please find the images inserted. Wifi enable/disable option is greyed out.

Keyboard and trackpad stop working after upgrade to Ventura 13.0.1 After i upgraded my macbook pro M1 14" to Ventura 13.0.1, the keyboard (external Apple bluetooth keyboard as well as the built in one) and some functions of the trackpad and Bluetooth mouse stop working. If i restart the computer, they resume working for a short time but inevitably fail again regardless of what software I am using. The issue appeared immediately after upgrading to Ventura and no other updates are available.
