User-Agent: Opera/9.80 (X11; Linux x86_64; U; en) Presto/2.9.168 Version/11.52 My laptop has the following WiFi-card, which uses the iwl4965-driver: Intel Corporation PRO/Wireless 4965 AG or AGN [Kedron] Network Connection (rev 61) Since upgrading to Fedora from Ubuntu, which used the iwlagn-driver, the quality of my WiFi connection has been very bad. I mostly experience problems making TCP/IP-connections and bad performance with 11n disabled and occasional high ping and packet loss added when 11n is enabled. Reproducible: Always Steps to Reproduce: 1. Try to use the network with the iwl4965-driver out of the box Actual Results: Bad performance, problems making TCP/IP-connections, occasional high ping and packet loss Expected Results: Good performance, no problems with connections or ping and no packet loss There are some messages continuously coming up in dmesg in 11n-mode, no messages with 11n_disable=1. Some snippets: iwl4965 0000:04:00.0: iwl4965_tx_agg_start on ra = e0:69:95:98:88:34 tid = 0 iwl4965 0000:04:00.0: Aggregation not enabled for tid 0 because load = 0 Also happening with tid 2, but much less frequently.
Which kernel version was on ubuntu? There are lots of regressions on iwl4965, introduced between 2.6.38 and 2.6.39, where Intel split driver between iwlwifi and iwlegacy. I'm trying to fix them but it take time. If you used ubuntu with 2.6.38 kernel or older, that would be regression I mension. If ubuntu has newer kernel, that mean the bug is caused by different behaviour of user space i.e. NetworkManager.
I used 2.6.37 vanilla with the iwlagn-driver. So yeah, that must have been before the split is I now use the iwl4965-driver.
[mass update] kernel-3.3.0-4.fc16 has been pushed to the Fedora 16 stable repository. Please retest with this update.
If this still happen on 3.4 or never please reopen that bug, I'm closing it.
