"semi EOL". Dell hasnt released any updated bios nor drivers anymore for the Venue 8 Pro since years. Yes, it is literally dead. And all the drivers are unstable, especially the wifi one.
All the drivers for the Venue 8 Pro work fine for me. The WiFi issue maybe a hardware issue and not a driver issue. Why would Dell update the BIOS, it not like you can install upgraded hardware.that requires new BIOS features.
