Hi, I have Intel 6300 on my laptop: 02:00.0 Network controller [0280]: Intel Corporation Centrino Ultimate-N 6300 [8086:4238] (rev 35) And since I have had this laptop (1,5 years now) I have had to disable 11n (11n_disable=1) to get stable wifi, otherwise the TCP connections would stall or get really slow. I have been hoping to properly debug this at some point but, as usual, never found the time for it. But today I noticed that this is still a very common problem: https://plus.google.com/u/0/100920064738447422284/posts/Q32wEwyumdC Does anyone know what's causing this? Is this bug (or bugs) tracked anywhere? My AP is Netgear WNDR3700 running openwrt (10.03, r25221) and ath9k. Laptop is Lenovo x201 running Ubuntu 12.04.1 64 bit with various different kernels. -- Kalle Valo -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
