Don't know if it is the same, but I can't connect to my wireless network from a Dell Studio 1749. It seems like my networkcard starts to rescan before it even can't connect.
Everything was working well on 11.04 and shortly after an update to 11.10beta. Troubles began with updating about a week ago. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/836250 Title: [Oneiric] Intel Corporation Centrino Ultimate-N 6300 poor networking, packet loss and very slow Lenovo X201 and T500 laptops Status in “linux” package in Ubuntu: Confirmed Status in “network-manager” package in Ubuntu: Confirmed Status in “linux” source package in Oneiric: Confirmed Status in “network-manager” source package in Oneiric: Confirmed Bug description: This may be either network-manager or kernel, depending on triage... I have verified this on both a Lenovo X201 and a Lenovo T500 laptop. Both work perfectly with fully updated 10.10 and 11.04 versions of Ubuntu. However, booting into a fully updated 11.10 (as of 28/08/11) I get very poor wireless networking performance. Between 6-10% packet loss, very very slow connection and transfer rate. All in all, practically unusable. I have reported the bug on the X201 laptop, I will add the similar logs from the T500 also if required. As soon as I swap back to either 10.10 or 11.04 I get perfect wireless, it's only on 11.10 that I get problems, this would suggest it's not hardware or configuration on my side. I have had this since first installing 11.10 which was a little after Alpha 2. Wired connection is fine.
