Apple admits some iPad users may have trouble staying connected to the internet, confirming reports from customers who purchased the new devices over the weekend.
The first generation of iPads accesses the internet using Wi-Fi networks. "Under certain conditions, iPad may not automatically rejoin a known Wi-Fi network after restart or waking from sleep," says a statement on the Apple support page.
The company says this can happen with "some third party Wi-Fi routers that are dual-band capable", and when both of those networks share the same network name, or when each band has a different security setting.
Wired reports that the dual-band routers are those compatible with both 2.4-GHz and 5-GHz spectrum bands, and usually both bands work as one network with the same name and password.
Rather than fix the iPad, Apple is suggesting customers fix their routers. Apple recommends users separate the two networks and "create separate Wi-Fi network names to identify each band--Example: Add a G to the 802.11b/g network name and an N to the 802.11n network name."
It also says users should make sure both networks "use the same security type (WEP, WPA, WPA2, etc)." If that doesn't work, Apple recommends that customers reset the network settings on the iPad.
Some iPad users have complained their internet connections are weak, even in areas where the Wi-Fi connection remained strong for iPhones. "My new iPad experiences great difficulty remembering/connecting to my home network," tweeted David Chen in Boston.
"Signal is spotty as we moved away from router," said Wall Street Strategies retail analyst Brian Sozzi. A second version of the iPad coming out at the end of this month will allow users to connect to the internet using 3G cellular telephone networks.
