I'm experiencing the same issues with the XPS13 (A08) and Ubuntu 13.04. The WiFi frequently slows down, and pings to my router vary from 1ms to 1000ms and sometimes >10,000ms. I've both tried disabling power saving on the wifi card, and also disabling 802.11n (which drastically reduced cut-outs, but not eliminated them).
When this slowdown occurs, all other devices connected to the same router also suffer from poor connection speed. It is immediately rectified if I disable wifi on the XPS 13. However, the connection is still very unstable compared to other machines on the same network. At it's best, it's as fast as my other laptop. As it's worst, it gets 0kb/s for seconds at a time... it seems to alternate between each state every couple minutes (as evidenced by my Steam download graphs!) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1091372 Title: wifi slows and/or drops frequently To manage notifications about this bug go to: https://bugs.launchpad.net/dell-sputnik/+bug/1091372/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
