Also, there is no mac filtering presently set.

Subject: [sdw2003] Wierd Question about Wireless- new laptop not getting IPaddress

What we have:

2 Linksys WAP 4400N Access Points
On a domain- with DC, DHCP, etc.

We have 15-18 laptops here of different age and time of use.  Lately we have purchased 5 new ones and other than wireless- all is well.  What we got here is that(when setup correctly like the other machines), the wireless nics on the newest laptops are in a vicious cycle of acquiring the IP address and stopping> acquiring IP( all day long).  I can tell you that there are sufficient IPs in DHCP(50-60% free) and the gui for the WAPs are accessible(and all looks fine there).  I am using all the correct config into to grant access.  Nothing has changed from the stand point of the WAPs.  

At home I have no trouble to connect to my WAP.  Our WAP is the only one that seems to reject these machines.  Linksys is no help(because the WAPs are responding as desired for others) and the WAPs have no logs to really track the discussion between the NIC and WAP/DHCP(not that I am aware of).  What is strange is the fact that the older machines continue to be connected and not manifest the same behavior.  Only the new MACs to the WAP or DHCP seems to have problems.   

This issue is really bothering me and I am confused.  Nothing I do seems to make any difference at this point.  CJ
