To check if the Fenvi card is defective I would suggest installing it in a Windows 10 system. You would need to manually set/change the Wireless channel on your router to fix this. See screenshot below:īoth using Channel 44, moving your AM wireless network to another channel might help with the throughput. You might want to look at changing the Channel for the AM Wireless network, as you are using the same channel that AirDrop uses by default.

Please let me know if you need more information about the current build.īig Sur won't work with the standard AirportBrcmFixup.kext.Am I missing something? Should I use any particular kext or change my actual EFI config?.Could this be a defective card? How could I check that?.Disconnect Bluetooth, no noticeable improvement (I'm not injecting any BT kext).Move the card to a different Pci slot, no noticeable improvement.Installed AirportBrcmFixup, no noticeable improvement (TBH I got confused when reading this, I'm afraid it's not as simple as installing the kext, but not sure what should I do there).Use the TPLink antennas, no noticeable improvement.Tried to remove some of the antennas, no noticeable improvement. Activated beamforming in the router, slight improvement.Disable 2.4GHz in the router, no noticeable improvement.I've moved the tower just next to the router and the values improve a little, but still having a very low RSSI (~80dBM).I saw other users mentioning the same problem, but couldn't find any thread with the same problem.Ĭomparing both cards (see the screenshot, you will find the TPLink vs Fenvi), I found it quite odd that the RSSI is so low in the Fenvi, and I guess that is the biggest indicator of why I get a slow connection: Know the sad news is that the signal strength and speed are slow, even slower than the TPLink I had before, which I don't understand. At this moment I'm not worried about the BT, one problem at a time I've removed the previous kexts, installed the card and it simply works! AirDrop is there and it actually works. Grabbed a Fenvi T919 since I read good feedback about the card (that works OOB) and I could finally connect to ac network. Thought about upgrading the card since I would like to have higher speeds, I'm working on a MacBook Pro and that sits in the same desk and the Wifi speed is almost double in the MBP. I have a TPLink (TL-WDN4800) 450Mbps wifi card that works using both I O80211Family.kext and AirPortAtheros40.kext. I've recently moved from Clover to OpenCore and I'm on BigSur (11.2.3).
