even with current 5.4 kernels from 20.04 (9 years after this bug was reported), it's neccessary to set
options iwlwifi 11n_disable=2 if you have a Intel Centrino Ultimate-N 6300 card. Otherwise there is packet loss that prevents usable throughput rates. If this is not getting fixed upstream in the kernel, then Ubuntu should ship a configuration for systems with those chipsets, that mitigates the problem. Finding the cause of this problem is only possible for people with expert knowledge. Can you please add a mitigation for this issue in Ubuntu by default? -- 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: 8086:4238 Intel 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 [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
