wpa fails with draytek vigor 2600 series routers
Last modified: 2009-09-08 09:29:17 UTC
reproduced here. the mac mini can connect, but sb2 with fw13 can not.
Can connect via WPA with Netgear WG311T but SB2 fails on Draytek 2600G
oh no, did this not get fixed??
Urgh...spent many hours trying to debug this to no avail. The problem seems to be in the 4-way handshake that's part of the start of a WPA session. The Draytek AP reports a "TKIP frame error (MIC)" and then times out on the handshake. This is in response to the EAPOL key response (the 2nd in the handshake) from the SB2. This is similar to problems noted in: http://forum.draytek.com.au/index.php?showtopic=725 and http://forum.2-com.de/draytek-vigor-thema2838.html I've also noticed that with firmware 2.5.6, the Draytek AP seems to send the 3rd handshake packet immediately after the 1st, without waiting for the response from the station. This doesn't seem to happen with 2.5.4, but the MIC error still occurs. I tried going back to earlier firmware revs, but had problems getting the WLAN to work at all. The MIC (Message Integrity Check) generation algorithm is fairly well established, so I'm not sure what the problem would be...especially since we work perfectly well with other APs that support WPA-PSK. The frame generated by the SB2 itself seems to be identically structured to those from another station (a Mac laptop) that was able to successfully connect. If anyone has success installing and testing with Draytek firmware revs under 2.5.4, I'd be curious to know the results.
Sounds like a bug in the draytek. Has somebody contacted their support folks?
Submitted a bug report Draytek Taiwan. Draytek Ticket Number is 2005071810000337 Got a reply asking for: 1. The 2600G's config file. 2. The user Manual of the Squeezebox2. 3. Please make some screenshots of the WLAN settings on the Squeezebox. 4. Please capture packets while you're connecting Slim to Vigor with WPA encryption, then mail it to us. I did 1, 2 & 3 but I have directed them here and asked them to contact Vidur for ethereal logs as I can't set my network adapter to promiscuous mode under Windows. Hopefully we can get this resolved.
Created attachment 707 [details] draytek dump--vidur may need to comment on the contents
Created attachment 708 [details] second draytek dump marked deauth--vidur??
Vidur to update Draytek on the issue.
I have been testing with a Draytek vigor 2800 and WPA and WPA2 are fixed in firmware 43. I assume this means the vigor 2600 will now also work. This version is now in test and should be released tomorrow. Please re-open the bug if you still have problems once the new firmware is released. At the moment the WEP+WPA mode in this router does not work.
Firmware 43 is working with WPA2 on my Draytek 2600G using modem firmware 2.5.7
This bug was fixed with the 6.2.2 release which included fw48. If anyone is still having issues, they can re-open the bug.
