From mboxrd@z Thu Jan 1 00:00:00 1970 From: Thomas Gabriel Date: Sun, 04 Oct 2009 14:58:43 +0200 Subject: [ath9k-devel] Performance Issues with BGN TP-Link TL-WN951N Message-ID: <20091004125843.210690@gmx.net> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: ath9k-devel@lists.ath9k.org Hello togethter, i just bought a WN951N BGN Atheros based 3*3 MIMO Card for my Linux-box to act as AP in Mastermode for my new N-Network. On The other Side there is an Atheros based D-Link DWA-160 (Rev A) ABGN USB-Card connected to a Windows XP Laptop. thee good: The WN951N just worked out of the box with a new kernel and newest hostap-version. After i played arround with the hostap.conf (especially with the ht_capab param) i get a stable link-connecten. but performance is not that good i expected. I made a few test with uploading a 1 GIG file to / from the Linux Box: WN951N --> DWA-160: 5713,27KB/s DWA-160 --> WN951N : 5292,08KB/s Windows display during these test in the WLAN-Utility a Link-Speed between 240 and 300 MBit. When i put some of the [SHORT-GI-40] or [GF] or [SMPS-STATIC] parameters in the hostap.conf, hostapd wont start (in case of [GF] or [SMPS-STATIC]: not supported by device) or the link between WN951N and DWA-160 always disconnects after a fews seconds (in case of [SHORT-GI-40]). do you have any hints for me for better link performance? PS: Are there actually 3*3 MIMO ABGN (DUAL-Band) PCI-Cards (not miniPCI) aviable supported by ATH9K? Will there be a possibility to put one card in master-mode in A and G mode simulaniously - so i have 2 AP's with one card?

This functionality can be used both as a local authentication server # for IEEE 802.1X/EAPOL and as a RADIUS server for other devices. # Use integrated EAP server instead of external RADIUS authentication # server.
