Hey guys, I've just noticed an issue after I wake my laptop up from sleep, the wifi network connects back up as normal but I lose internet connectivity, swapping to other networks fixes it for a split second but am not able to get working internet until I restart / shut down. Now I have full functionality of the Wifi Card as shown here including 5GHZ and AC speeds.

These are the patches I'm using atm for the BCM4352, this is GM drivers so maybe it could be that they're not fully compatible?

Why two whitelist patches?
And FakePCIID is a better solution for Airport branding than the patch.

To be honest I just left them there as I pasted them in from Toledo's patches. But I took your advice and removed them as well as the Airport brander and replaced it with your PCIID kext in the EFI folder and it seems like it was working but after a minute or two the unresponsive internet repeated itself, but unlike last time swapping network connections seems to resolve it temporarily. Strange

Started diagnosing the issue a little more, the current clover patches that I'm using for BCM4352 card on El Capitan are exactly the same as the ones for Yosemite. I've also noticed I only lose connection to the WiFi network I was connected to previously, (In my case Khan 5G) swapping to Khan 2G gives me internet access however connecting back to Khan 5G results in unusable internet after a few seconds of browsing.

Could this be patch related or DSDT related?

5ghz patch is the same 10.10/10.11.
BT handoff patch is different 10.10/10.11.

There are no DSDT patches required for BCM4352, so I'm not sure what you're referring to.

I mean the loss of my current Wifi network and inability to have internet access with it after sleep, could it be due to a messy DSDT? When dual booting onto windows 10 it doesn't seem to have this issue and neither did Yosemite before my upgrade.

I'm not sure what you mean by "messy DSDT".

Probably the wrong word to use, but just patches that are applied and that shouldn't be there I guess, when originally trying to get my laptop to full functionality in Yosemite I did a lot of unnecessary patching back then.

Maybe. You can always do it over.

So I just tried your suggestion, I made a new DSDT and patched it accordingly with the USB 7 Series/8Series patch as well as the XHCI through USB 2.0 patches as well as some others that I normally do and still the same result.

However I tried a completely untouched DSDT (One i got from using clover) and there seems to be no wifi issue on wake!

However by using my raw DSDT Im suffering from the instant wake issue once again. So Ill have to try and isolate which of those 3 patches I mentioned above will fix instant wake but not affect it so the wifi isn't messed up.
