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.

I'm seeing significant slow downs and drops on several networks. Two main issues: 1) Wifi slows down significantly for 10-60 seconds. It appears no packets are getting through, as all browser requests churn, Flash games show connection errors, pings don't work, and Software Center/Update Manager/apt cannot connect. The connection always returns eventually. This is happening once every few hours to many times an hour. 2) The wifi connection disconnects and quickly reconnects. This is also happening between once every few hours to several times an hour. I cannot spot a pattern or a trigger, but it's happening a lot. It's occurred on all three networks I've connected on. Two were standard secured home wireless networks, and one is a corporate wireless network. I have the Sputnik sources that shipped with my Linux installation, and added the two PPAs as well. I'm happy to provide logging or try some debugging steps -- please let me know how I can help. --- AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24.
