Comment 49 for bug 1091372

Michael: Before switching to an unsupported kernel, please use first try the linux-image-generic-lts-raring kernel. Since you're using an old BIOS version, please update that as well. Also, if you bought the XPS 13 Developer Edition, note that you are entitled to help from Dell ProSupport. (I am with Dell but not in ProSupport. Also, note that ProSupport is different from our normal consumer support. I'm sorry that you've had bad experiences with us in the past.) It would really help us with resolving wireless issues if our support people were able to work directly with you on this issue.
