After checking the Proxies, APNs Server and TCP Ports, things are very easy to
solve by paying attention to your Wi-Fi coverage and capacity.
There are two different scenarios:
If your school is currently planning an iPad deployment, thinking about the Network coverage and capacity should be the first step. But, if you’re part of a school that has already deployed iPads and are facing issues, it’s important to first check the proxies and firewalls, and then investigate the infrastructure.
Make sure the Wi-Fi signal reaches all areas where Wi-Fi will be used. You’ll need to consider not only classrooms, but also common spaces, such as the gym and cafeteria. The power output of each access point will need to be reduced to prevent the Wi-Fi signal of one access point crossing into multiple classrooms. So, be sure to plan the distribution of access points according to the channels. Make sure your network supports the number of devices at your school. This will impact the amount of access points your institution will need.
Tip: Check out the signal quality setting of the school access points. If
the device is being used far from the access point and a minimum quality is not
setup, the device will keep the connection but the quality will not be sufficient
to receive commands. It is recommended to setup the access point to a higher
minimum quality, and when the signal is lower, the connection will drop.
Keep in mind the access points should only serve to distribute Wi-Fi - not amplify the network signal. Because of this, it’s best practice to plug each access point into the network via cable. In doing this, you’ll drastically reduce any interferences in your Wi-Fi.
