Assuming you have the latest intel wifi kexts, and your bios is setup correctly everything should work the same with the L13. From what I can tell it has the same WiFi/Bluetooth card as the Yoga I have (some newer Yogas come with the AX201). Check your settings and config.plist to ensure it is setup correctly. Maybe reset you nvram. Otherwise I'd have to take a look at your EFI folder to offer further suggestions.

Resetting NVRAM or just hard reset of the notebook might help. The hard reset swich of the notebook is at the middle of the buttom. Also take care as sometimes the system does not boot, as some data is preserved in the NVRAM.

Following up on the issue with Airdrop. Seems to be a limitation of the Intel WiFi kext:

Does it support Apple's Continuity Framework (Airdrop, HandOff)
Only Handoff and Universal Clipboard works with AirportItlwm, other features are not supported.

Handoff and Universal Clipboard are the only supported Continuity features

I just noticed the released a new version of itlwm for Intel wireless cards. Maybe give it a try.

Answer 5 · 2021-04-21T21:14:40.000Z

I can confirm, the new version of itlwm really improves the experience. I get now 110mbit/s instead of 30. It also seems less buggy, but I've only been using it for a day or so.

hi,I updated AirportItlwm_v1.3.0_stable_BigSur.kext,WIFI can work well.Thanks for everyone.

For me it did not work, so I had ro revert to v1.2. Did you upgrade the opencore to 6.8 too?

Answer 8 · 2021-04-29T09:29:43.000Z

I stayed on 0.6.7 and it worked fine. Odd, what macOS version are you running?

Answer 9 · 2021-04-29T09:47:09.000Z

Big Sur 11.2.3

Answer 10 · 2021-04-29T12:35:33.000Z

Big Sur 11.2.3,Open Core 0.6.6

@sdombora same for me, odd. Do you get any error messages when booting in verbose mode?

I did not look at it, I had connection issues - the WPA2 connection was recognized as WPA and I had a warning that the encryption is weak, and the connection was dropped frequently too.

@DAlexis74 I'm similar to hagenest and sdombora. I haven't experienced any of the issues you've described after updating to v1.3 with OC 0.6.7. I plan to update to MacOS 11.3 and OC 0.6.9 next week when it comes out. I'll update the guide when successful.
