A small number of routers are not compatible with the LeapPad or may require additional steps to connect.
The vast majority of routers operate on 2.4GHz. LeapPad's Wi-Fi operates on 802.11 b/g/n 2.4GHz networks and won't be able to find your network if the router is in 5GHz only mode.
Check your router's manual to verify you are not using it in 5GHz only mode.
This troubleshooting tip applies to LeapPad Ultra only.
The LeapPad may require a firmware update before it can communicate with the combined modem/routers supplied by TalkTalk or Sky.
To get this firmware update:
Some routers such as the Linksys E series have a secondary network in addition to the main network. On these routers you must use the main network to connect the LeapPad.
This refers to using a wireless device such as a laptop to create a network, rather than using a router to broadcast Wi-Fi.
A router assigns an IP address to each connecting device. An ad-hoc network requires the user to assign an IP address to each connecting device. The LeapPad does not have a feature where you can assign an IP address, so you would not be able to connect it to an ad-hoc network.
