Hello, I have a strange problem. I have about 65 users using wpa+PEAP+FreeRadius with Linksys WAP4400n APs. I have 3 buildings with 19 AP's per building using POE and wired back to a switch and each switch in each building uses an ethernet cable to tie into the main switch connected to the server. I have no LDAP or mysql backend and am just using the users file. Here is one of my users in the users file that is having problems: username Calling-Station-Id != "00-0F-B5-B5-35-2E", Auth-Type := Reject username User-Password == "password" Now this user sometimes connects successfully and sometimes he gets this error: Mon Feb 19 17:06:42 2007 : Auth: Login incorrect: [username/<no User-Password attribute>] (from client ShmAp-12 port 0 cli 00-0F-B5-B5-35-2E) Mon Feb 19 17:07:44 2007 : Auth: Login OK: [username] (from client UNKNOWN-CLIENT port 0) Notice the timestamp, this is not the only user this happens to about 20 of about 70 people on this setup. Please let me know what information I could provide that would help isolate this problem. I have found a hotfix put out by Microsoft, hotfix# 885453-x86 and it seems promising but I want to do some more testing before I recommend it. Thanks for any help or ideas, Jon
