Dell Studio 1747 with Broadcom BCM43224/4353 here. It would see and connect to the router, but zero traffic happening.
I have now disabled 802.11N directly in the router and am using G instead. This works fine, but should only be seen as a temporary workaround. While troubleshooting, I was connected by cable as well as by the "zero- traffic" wifi connection. I noticed then (when being logged in to the router) that my router was seeing both connections, but listed them BOTH with the SAME MAC-address, namely that of my ethernet adapter. Just hoping that this observation helps with solving the problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to 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 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/836250/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
