      Hello!

      I´m using a Pentium 4 with Pfsense 1.2.3.

      Using a USB WLAN Stick (b/g) i configured a AP with WPA2/AES.
      Everything works fine if the client have a Mac or Windows XP System.

      But if i try to connect with a Win7 PC the pfsense didnt give me a valid IP.

      I tryed the same Notebook Hardware first with xp(this works) and then with win7(doesnt work?)

      I treyed the AP in WPA, WPA2 and Both, TKIP, AES and both, different channels, without any password. Nothing works with win7???

      Have anyone a solution? ???

        I have a 64-bit Win7 laptop on my home network that successfully gets an IP address by DHCP from pfSense 1.2.3 over wireless encrypted WPA2/AES.

        What status does Win7 report for the connection?

        Have you looked in the DHCP logs to see if pfSense sees the DHCP request from the Win7?

        I had two Win Vista laptops on the home network that all of sudden (and at apparently independent times) stopped responding to DHCP assignments. A search through the Microsoft knowledge base suggested a registry patch might help and it did.

          THats wiered?!

          My RUM0 adapter(wlan) hast the ip 192.168.4.1 and the dhcp range is .90 to .99

          But if i try to connect with my win7 x64 notebook (in the ip4 tcpip ist auto ip selectet!) then the pfsense give me this log in the systemlog dhcp:

          dhcpd: DHCPNAK on 192.168.10.130 to 00:13:02:02:10:92 via rum0
          dhcpd: DHCPREQUEST for 192.168.10.130 from 00:13:02:02:10:92 via rum0: wrong network.

          The wierd thing is that the 192.168.10.0 Network is my home wlan but now iam in my business building?! In my home Wlan i use a EDIMAX N AP. and it works there. The last ip the EDIMAX gave my Notebook yesterday was the 192.168.10.130?

          But why is this happen.

          I tryed to connect with two other notbooks with win7x64 and win7x32 but the pfsense always give me the same message????
          (all of them i usesd yesterday on my home wan?)

            If you leave it connected for several minutes, does it eventually get an IP address from there?

                Maybe DHCP tried to renew your previous lease. Did you try releasing the DHCP lease before connecting to the new network?

                Is there anything about the two networks (home and business) that might lead Win7 to think they are the same network (for example same SSID)?

                    It does look as if Win7 is trying to renew the lease as if it thinks its on the same network (possibly due to a software bug).

                    Did you try releasing the DHCP lease on Win7?

                      This might be some kind of bug (or feature?) in the DHCP server used on pfSense.  I haven't seen it happen with the DHCP server on at least one other non-pfSense router I have.  They just give out a new IP anyway if the client requested something outside of the subnet or DHCP address range.

                        Yes i know! I have a secound WLAN in my business named with a nother SSID and if i connect to this i get a IP from the PFSENSE.(thats how i set it up).

                        But if i connect to the pfsense WLAN it doesnot work.

                        The interesting thing is that every XP Notebook works. And every Vista or Win7 Notebooks doesnt.

                        =?????? ???
