[solved] BCM94352Z has slow wifi speed with BT

[rexx0520]

I have fully enabled the Wifi and BT function by several different ways, but they all comes with a problem--When BT is enabled,the wifi speed is extremely slow.
When the BT is disabled, the speed comes back.
Windows does not come with the issue.
Has anyone ever faced the issue before?The problem also occurs on Sierra..

You're using 5ghz or 2.4ghz?

You're using 5ghz or 2.4ghz?

2.4 ghz
but 5ghz also slows down with BT enabled

The speed is well on Windows, so it should not be a hardware issue.
Have tried several different ways including Clover fix, SSDT, AirportBrcmFixup... all of them have the same issue, so it should not be an operating issue..

Make sure "Wake for network access" is disabled in SysPrefs->Energy Saver.

Otherwise...

Should be interesting... sounds like you tried a lot of wrong methods.

I dont think so...
The new method is absolutely easy.Simply install BrcmPatchRAM2 and the Repo kext, FakePCIID and _Broadcom_Wifi in L/E, Lilu and AirportBrcmFixup in Clover/kexts/Other
And the Wifi and BT is enabled with Handoff and LE.(Seems that AirportBrcmFixup will automatically fix the Handoff and LE problem?)
