Hello,
I've installed Mojave on my Dell E7440, and everything is working except for WiFi, original WiFi card was an Intel card, I've replaced it with a WiFi card DW1703 got some kext from YouTube and installed in on S/L/E, WiFi card is active but websites are taking a lot to load (around 3 minutes) I've checked the WiFi card on a Windows drive and everything is okay.
I ran a test on speedtest and got 0.03mb/s download and 0.01 mb/s upload, how can i fix this?
