I have a Telewell TW-EA510v4 ADSL modem+WLAN router configured as follows:
Mode: 802.11b+g Security Mode: WPA1 Pre-shared Key WPA Algorithms: TKIP
Connections from only certain MAC addresses have been allowed and the MAC address of my Mac is in that list. The WLAN works just fine with iPhone and an old Acer laptop.
It has worked for about two months or so with my MacBook Pro (year and a half or so old model). Ocassionally i've had minor problems with it, which have required either reboot of ADSL modem or reboot of my Mac. However now, for the last week or so I haven't been able to connect to it at all.
This is what is what i get in the console when i try to connect:
5.5.2010 20.54.53 airportd Apple80211Associate() failed -3924 (Invalid PMK) 5.5.2010 20.54.53 Apple80211 framework airportd MIG failed (Associate Event) = -3924 (Invalid PMK) (port = 104599) 5.5.2010 20.54.53 SystemUIServer Error joining WLAN-M: Invalid password (-3924 Invalid master key)
The pre-shared key I use is not incorrect. I'm 100% sure of that.
The Error Log from the router only says this when I try to connect to it:
May 05 21:09:54 home.gateway:i802_1x:none: <my mac address> associated May 05 21:10:00 home.gateway:i802_1x:none: <my mac address> disassociated May 05 21:10:01 home.gateway:i802_1x:none: <my mac address> disassociated
Any ideas or tips to troubleshoot this further?
