Our Lan e Wlan are based on Cisco devices. But now, we are experiencing some strange behavior on our Wireless network. Here, we deployed a simple wireless environment, since our needed are very simple: just permit internet access to academic community from all places in the campus. So, we bought AP Aironet 1100 and 1200 series and put it on strategic places on each build. Ok, it was simple. Coverage area Ok! :). But now, I'm investigating a strange situation: the client connect on the wlan (without WEP/WPA, etc), but it cannot receive a IP Address from DHCP Server. I checked my core switch, edge switches, my dhcp server (a linux box), re-certified the cables that connect AP to edge switch, change DHCP Server from Linux box to MS DHCP Server, and back to linux again.. etc etc ... without successful The problem don't have a specific period, or specific location or any relation with some event. Just the clients cannot connect on WLan (in fact, they connect, but don't receive a ip address). On my dhcp server log, I saw the DHCP DISCOVER packet from client, and the DHCP OFFER, from my DhcpServer to client. If I restart access-point, the problem is temporary solved. (Look, this strange behavior occurs with all 1100 and 1200 AP's, on different time, on different days, without a logical order). Did anyone experienced any problem like this during the deployment of Wlan environment ? Unfortunately our Cisco partner just limited to sell and deliver the equipment Sorry about my bad English, and my long post Best Regards -- Alexandre Bastos -------------------------- Fundação Edson Queiroz Universidade de Fortaleza Gerência em Tecnologia da Informação - GTI ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/. ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/.
