Good coverage but the speed go down!!! Please Advice.
Hi all, i have a 4402 controller with 17 ap on line, i am using this system to give wireless service to several machine in a manufacturing plant, if i go to the terminal the coverage is very good but the speed on the card go down until only get 1 MB of speed. I am wondering if this is problem of overlapping, saturatio IT's a big problem., please advice.
Re: Good coverage but the speed go down!!! Please Advice.
likely you have a lot of noise in your your environment. Review your SNR via 'show dot11 ass all'
this could be caused by co-channel interference (CCI), where two APs are on say channel 1.. Or it may be adjacent channel interference (ACI) which is when you have one ap on channel 1 and the other is say on channel 3. Other sources COULD be machinery, cordless phones, microwaves etc.
You may want to look into borrowing/renting/buying a spectrum analyzer.
