Apple has posted a knowledge base article addressing a problem where some iPads do not automatically rejoin known Wi-Fi networks.
Symptoms
Under certain conditions, iPad may not automatically rejoin a known Wi-Fi network after restart or waking from sleep. This can occur with some third-party Wi-Fi routers that are dual-band capable when:
● Using the same network name for each network
● Using different security settings for each network
Resolution
If you encounter this issue, try the following:
● Create separate Wi-Fi network names to identify each band. This can be done easily by appending one or more characters to the current network name.
o Example: Add a G to the 802.11b/g network name and an N to the 802.11n network name.
● Ensure that both networks use the same security type (WEP, WPA, WPA2, and so on)
If the issue persists, reset your network settings using Settings > General > Reset > Reset Network Settings.
