Ever since a recent power outage I've been unable to connect to wifi using my IPad. All blue lights on router are blinking. Tried resetting to no avail. Called customer service and, being out of warranty, they tried to set me up with one of their "plans" to rectify. Tried reconfiguring using info. on their website but when I type 192.168.1.1 into Safari it says, "Safari can't open the page because the server where this page is located isn't responding." There must be a way to rectify this without having to pay for it. Everything was working fine before the power outage.
Perhaps you can use the "reset" button to revert the router to it's factory settings. There is a recessed reset switch on the back of most modems. First unplug the router for a minute to two then power it back on and press and hold the reset switch of 10 seconds. Your router with then be reset to factory settings. The ID and passwords will probably be set to "admin". You can Google "Linksys router defaults" to confirm the settings.
