I have the same problem, and it is very frustrating. I have my old Dell Inspiron 1505E with xp, and it never does this. I am new to computers, so this is hard for me. I get limited access with yellow warning triangle over the bars and can't connect. Sometimes it drops every minute, like tonight. This morning not so bad. Dell has to know about this problem and should fix it. I would love to take this computer back, but I'm sure another one will do the same thing.
I tried this settings in my dell inspiron 3521 laptop and it fixed the wifi issue. Thanks a lot Saharsh and Dell Support. I have been facing this issue for almost a year... luckily i found this answer few days back. it would be great if Dell optimizes the driver or provide support with these steps in the mydell application itself.
try bridging your network adapters on your laptop. go to the control panel and you know where in networking and while the connection is active just select both adapters and right click and select bridge connection.

My laptop is a Dell E4300 with dual boot Linux/Windows.

I tried all the software solutions but didn't help even after I had all the right version and settings. So I opened up the laptop (we were past warantee and would have cost the same amount we spent for the laptop to have someone take a look at it), disconnected and reconnected the wifi network card/adpater (there are video instructions on the internet), and afterward haven't had any problem since. Something must have gone loose. The model we have the card was under the keyboard.
