Things affecting the wireless comm.,

1. congestion >> since air is the shared media, frame retransmission also happens when transmission fails

2. Interference could also b a reason

3. Using broad bandwidth channels are prone to this

Please check for the number of clients , any overload situation ?

thanks , i found there were no more than 20 clients on one aps.

we have a 2504 WLC configured with 5 ssids. and a 5508 WLC configured with another 4 ssids.

is there any conflict between the two WLCs.

Hi,

get show ap auto-rf 802.11b or a <AP-NAME> and check whats near.

connect 1 client and see if that makes a difference.
