Wireless Access Point problem please help/advice
We have a 4 wireless Access Points in our science department, one in each classroom the brand of the access points are Planet. We have 18 laptops that students use for each lesson to connect to the network wirelessly. The AP are configured to pick up IP from our PDC and WPA PSK security is set. But the laptops are connecting very intermittently and sometimes they search for IP for minutes and eventuly say SLOW OR NO CONNECTIVITY. We have done the following:
, Laptops are updated with all Microsoft updates
, The network cards of all 18 laptops are upgraded (from the manufacturers websit Intel)
, Planet technical support were of no help
, Firmware updates were not authorized by the Planet, they think the firmware is up to date
I strongly believe that these AP are total rubbish and there is something wrong with hardware. We have now called our contractors who initially installed the APs to change it with a stable brand but they say they wont change it and blames our configuration (but how difficult is configuring an AP ?). but please Advice me of anything that you think i should do that you think i missed to do.
Also we are going to install another 8 AP, please advice me on what brand should we go for, that you think is good and will support 20 clients to connect to the AP in the same time.
