I have had a brand new Dell Precision 3541 for nearly a year now. Wifi speeds have been awful on it, download speed is never greater than 0.50mbps, whereas with ethernet wired connection on the laptop it is over 100mbps (same as every other wireless device I own). I have tried troubleshooting this as best as I can, I've installed new Wifi drivers, I've checked to see if SmartByte is installed and it doesn't seem to be. I'm really fed up, hopefully someone can help
