[Bug 836250] Re: [Oneiric] [Regression] Intel Corporation Centrino Ultimate-N 6300 poor networking, packet loss and very slow Lenovo X201 and T500 laptops
I would like to add that I have a Lenovo laptop with an Intel Centrino Wireless N (forget the model number) running Ubuntu 12.04 amd64 as well and that laptop does not experience any of the issues that my Samsung laptop faces. This makes me think that the issue might not be just a driver issue alone as this uses the iwlwifi driver as well. It probably is a combination of driver + model. -- Aravind -- 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] [Regression] 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/linux/+bug/836250/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

The power management and wireless-n disable changes did not help. Disabling IPv6 seems to have helped. I have still disabled power management and wireless-n though.

Hi. I have a Samsung laptop with Intel Centrino-N 130 wireless card. My wireless router is a Netgear WGR614v7. It only supports b/g. So, even if I am connecting to a 'g' network, my connection drops almost every minute and I have to disable and enable wireless connections for it to reconnect. I have tried the workarounds suggested - /sbin/iwconfig wlan0 power off and options iwlwifi 11n_disable=1 but both do not work for me. I have not tried both workarounds together though and will try that today. If that fails too, I think that I give a try with ndiswrapper and windows drivers. My question with ndiswrapper would be, how can I be sure that iwlwifi is not loaded and windows drivers are loaded? Do I blacklist iwlwifi?
