It sounds like you are focusing in on a radio problem but you have ignored the possibility of a traffic-related problem. You need to recognize that in a non-polling or a dynamic-polling environment, the upstream traffic from your clients will have an impact on the performance of your network and can quite literally overwhelm the processor on many access points.

One customer could be bringing the whole AP to a crawl, especially when they start pulling traffic. Look at customer re-transmits and see if you see any excessive problems. Make those customers better or turn them off for the benefit of the whole AP. 2.Have you tried changing frequencies. 900 is almost voodoo. Does your noise floor change? Has it changed since 10 days ago? 3.Have you tried changing feed cable as part of the re-wire process?

Backhaul to tower is TR-5plus 5.8 The AP is TR-902 NF with a 180 degree antenna. 50 TR-902-11 as clients All was working well until about 10 days ago when we noticed the speeds were starting to decline. Since then it is a nightmare speeds are usually good 3000Mbps up and 1.2 down] Then during the next 4-5 hour speed decline to about 100k up Speeds remain good and constant thru the backhaul We have done the following: Changed the AP Rewired the tower Replaced the power to the AP Any suggestions as to what problem is. We are a small company and this could break us NGL _____ ---------------------------------------------------------------------------- ---- WISPA Wants You!
