iPad is a new tablet from Apple which just started shipping to the customers. As happens with most of the devices in their first version, iPad also has some software level refinements needed to make it a reliable device. This is the reason why we have lots of firmware upgrade on our devices. Recently many customers who just started using their fresh new iPad devices have reported Apple iPad to have problem with joining the wireless Wi-Fi network.
The problem is that when iPad is restarted or wakes from sleep state, it fails to join the known and remembered WiFi wireless network.
As Explained by Apple :
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
Solution To iPad Unable To Join WiFi Network Error
To solve the problem of iPad not joining back the known wireless network, follow the steps below as suggested by Apple :
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.
- 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.
Note: Always ensure that your Wi-Fi router firmware is up to date.
