It installed kernel 2.6.34.7-0.3 built on 2010-09-20 Connection speed is 24Mbps-36Mbps - as router (DD-Wrt) says. Bandwidth Monitor reports 5Mbps to 10Mbps effective transfer rate (ftp download from server in local area network) So there is an improvement comparing to previous test environment/kernel. But connection speed is still below 54Mbps. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

At teh same time Connection Information shown by NetworkManager is 48Mbit, sometimes going up to 54Mbit. Pls also note Signal Quality at 60%, signal -44, noise -94, SNR 50. This is very strong, excellent signal! It means there is significant inconsistency between "connection speed" shown by DD-Wrt router (which is usually accurate on its data) and NetworkManager. Weird... BTW: as average download speed from OpenSUSE depository (downloading all updates recommended by YAST) is about 50KB-70KB/sec., and DD-Wrt Bandwidth Monitor shows max. transfer speed on Wireless (wl0) interface ~ 600Kbps, I think estimate of 2Mbps connection speed between AP and Wireless client is reasonable. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

AR9170usb is USB Wireless Adapter based on Atheros chipset (model TP-Link TL-WN821N). 802.11n, capable of 300Mbps transfer. Connection Information from NetworkManager also shows 1Mbit/sec., sometimes jumps to 6Mbit/sec.

This is new 802.11n Access Point, capable of 300Mbps (TP-Link TL-WR841ND Wireless Router, built on Atheros chipset). It is running native firmware. So, both Wi-Fi adapter and Access Point use same chipset, and should be able to communicate at 300Mbps (speed in Windows XP was close to this number) So, I think problem is not related to Access Point or adapter.

YAST software installer doesn't find any compat-wireless package

You can add http://download.opensuse.org/repositories/driver:/wireless/11.3-update/ as a repo to yast to install it and to have automatic updates...

For OpenSUSE 11.4 (nightly build) - Should I add http://download.opensuse.org/repositories/driver:/wireless/openSUSE_Factory/... repository to test up-to-date compat-wireless package, right? Are there any log files where I can check connectivity status and handshakes (association, authorization, "running", speed change, etc.)? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
