I updated AOL and since then I cannot get my Kindle HD to connect to my wireless (it says out of range when I'm sitting next to the router). My laptop and mobile phone with the same settings are working OK. Could the update of AOL cause the problem?
There is a big possibility that because of the update the WiFi settings changed. Use your Kindle and go to the Settings menu followed by Wireless. Select your own network and "forget" it, then perform a new scan and connect again. If you still have problems, try resetting the Kindle to its default state from Settings > Privacy.
