I have a Dell Inspiron M5010 that runs Windows 7 64-bit. Due to some technical difficulties I had to reinstall the OS. Now my computer will not connect wirelessly to my wireless router. I have connected to my router using an ethernet cable and it works just fine. While looking in the Device Manager I noticed that my network controller had the yellow triange with the exclaimation point. After opening up the properties it has indicated that"The drivers for this device are not installed. (Code 28)" I have gone to the Dell website, but I do not see anything listed under the drivers for my computer and when I do a search I get several hundred pages. Does anyone know which drive I can use to clear up this problem.
