Will Never shop Dell again! Purchased an expensive laptop a year ago, following 3 other dell computer purchases. At the time I had no knowledge about the difference in network cards. Well, apparently mine came with a single band and it cannot be upgraded to a dual band (what I need)! And NO ONE informed me of this when purchasing it. | I will never make a DELL purchase again! They lost a long time customer to Apple! I recently purchased a Mac and the dual band comes standard! Even my older PC comes with it standard. But I guess Dell expected me to know that I would need this then and pay even more for it then, as if I didn’t pay a lot to begin with. And now, in order to get what I want I would have to buy a entire new laptop system! This is highway robbery. | No worries, when I do purchase another laptop it will be a Mac. Because apparently they are built to last and grow with customers needs. With all of the Tri-band and dual band routers out on the market for year now, Dual band should be standard and if not standard, make it so that it can be upgraded if a customer so chooses! | I am on to you Dell. But that was the last dime of mine you will ever get! | I purchased my product speaking to a representative in America! Now anytime I need tech support (purchased a 3 year warranty) I am routed to India. What?! DELL is the absolute worst! and I am very dissatisfied. Just today I was transeferred 6 times in one call. I am not going to even go into how frustrating it is to be routed to people who cannot even assist you because they are outsourced employees only. Save yourself! Save your money! Save yourself the headache and buy APPLE! At least, they have locations that you can walk into to if you need tech support or customer support. Dell is done!
