Hello james1333,
For using 1 WAP561 here is the performance tested listed on the data sheet: http://www.cisco.com/c/en/us/products/collateral/wireless/small-business-500-series-wireless-access-points/data_sheet_c78-727995.html
Performance |
Wireless throughput | Up to 450 Mbps data rate (real-world throughput will vary) |
Recommended user support | Up to 64 connective users, 30 active users per radio |
Other issues that could cause issues:
Complex passwords, some devices make take to long to to process a complex password and it will cause connection issues and possibly delay in the processing of some devices.
The wireless environment. May need to use an app like: http://www.ampedwireless.com/wifianalytics/
This app will also let you know if other Access Points (AP) are using the same wireless channel as you.
Other aspects is your physical environment. You will want the best line of sight you can get to the AP to eliminate any interference of the signal.
Other than these basics if you need assistance with more diagnostics of the WAP561 I recommend to contact Cisco Technical Support to allow us to take a look at the AP.
Regards,
Michael D.
