[Desktop-packages] [Bug 836250] Re: [Oneiric] [Regression] Intel Corporation Centrino Ultimate-N 6300 poor networking, packet loss and very slow Lenovo X201 and T500 laptops
I believe I've found another interesting aspect to this issue. I believe it is actually capable of forcing my Motorola Surfboard 6120 cable modem to reboot. When using a wireless connection to do a git repo sync with Cyanogenmod (or anything that involves a substantial download), my cable modem will reboot every few minutes with the following logged errors. Cable Modem Reboot due to T4 timeout ;CM-MAC=XX:XX:XX:XX:XX:XX;CMTS-MAC=XX:XX:XX:XX:XX:XX;CM-QOS=1.1;CM-VER=3.0; Unicast Maintenance Ranging attempted - No response - Retries exhausted;CM-MAC=XX:XX:XX:XX:XX:XX;CMTS-MAC=XX:XX:XX:XX:XX:XX;CM-QOS=1.1;CM-VER=3.0; Ranging Request Retries exhausted;CM-MAC=XX:XX:XX:XX:XX:XX;CMTS-MAC=XX:XX:XX:XX:XX:XX;CM-QOS=1.1;CM-VER=3.0; No Ranging Response received - T3 time-out;CM-MAC=XX:XX:XX:XX:XX:XX;CMTS-MAC=XX:XX:XX:XX:XX:XX;CM-QOS=1.1;CM-VER=3.0; If I use a wired connection and disable wireless, I can do these synchronizes without a problem on the cable modem. Other machines on the network don't have issues, pointing directly at this Intel wireless problem. What I find most interesting about this is that there is a wireless router, switch and Linux router in the networking path within the house. I don't know enough about networking to understand how the wireless driver/hardware could possibly be creating packets that flow through the network and crater the cable modem. Very strange indeed. I'm pondering whether I need to re-install to roll back to 11.04 where networking was stable. I see that there is ongoing conversation with the Intel wireless driver folks, but does anyone have an idea if/when this might be fixed? -- 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] [Regression] Intel Corporation Centrino Ultimate-N 6300 poor networking, packet loss and very slow Lenovo X201 and T500 laptops Status in The Linux Kernel: In Progress Status in “linux” package in Ubuntu: Triaged Status in “network-manager” package in Ubuntu: Confirmed Status in “linux” source package in Oneiric: Triaged Status in “network-manager” source package in Oneiric: Confirmed Status in “linux” source package in Precise: Triaged Status in “network-manager” source package in Precise: Confirmed Bug description: This may be either network-manager or kernel, depending on triage...

After reading through this chain, I'm not entirely sure what I can/should do at this point to get a reasonably stable connection until all of the fixes come through. I'm on a Dell Studio 1558 machine with Intel Wireless card. When I start doing anything with any significant download, my Netgear WNDR3300 AP crashes and restarts. I had been running DD-WRT on that router, but based on these issues I reverted it to standard firmware with no improvements. I'm running in G mode, but I don't believe I have the disable N option set at this point. I'm also dealing with a backlight issue that Kamal fixed via PPA, so switching kernels is a bit tricky. $ - uname -a Linux craig-Studio15 3.0.0-14-generic #23+kamal~fix~stuck~backlight4-Ubuntu SMP Fri Nov 25 23:59:25 UT x86_64 x86_64 x86_64 GNU/Linux 03:00.0 Network controller: Intel Corporation Centrino Advanced-N 6200 (rev 35) I'm running Network manager and I'm willing to switch to WICD if it will get me a stable connection. I'm OK if the connection isn't N if it doesn't crash the AP. I would appreciate some direction on best approach for the short term. -- 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] [Regression] Intel Corporation Centrino Ultimate-N 6300 poor networking, packet loss and very slow Lenovo X201 and T500 laptops Status in The Linux Kernel: In Progress Status in “linux” package in Ubuntu: Triaged Status in “network-manager” package in Ubuntu: Confirmed Status in “linux” source package in Oneiric: Triaged Status in “network-manager” source package in Oneiric: Confirmed Status in “linux” source package in Precise: Triaged Status in “network-manager” source package in Precise: Confirmed Bug description: This may be either network-manager or kernel, depending on triage...
