Message-ID: <20101026104811.GA11357@pma.sysgo.com> Date: Tue, 26 Oct 2010 12:48:11 +0200 From: Pavel Machek <pma@...go.com> To: kernel list <linux-kernel@...r.kernel.org>, chunkeey@...glemail.com, linux-wireless@...r.kernel.org Subject: carl9170 disconnects under load Hi! I'm testing driver from -wireless testing, cca 2.6.26-rc7. It seems to work (up to 802.11n speeds -- I've seen iwconfig claiming 121 MB/sec), but disconnects rather quickly when under load: telnet 192.168.1.3 chargen > /dev/null The machine is powerpc mpc5200b board, with OHCI driver -- it is not capable of USB2.0 speeds. Any ideas?
