My wifi range extender stopped working after a few years. I plugged my desktop into it with a LAN cable and it gave excellent speeds and without it I'm on wifi N which just crawls. My range extender stopped working after a few years so I bought a new one, and couldn't get it to connect to the internet. So I returned it and bought a Linksys RE6300 but It has the same problem and won't connect to the internet either. I plug it in and follow the instructions. I select it from my phone's wifi list and it says that it will not automatically connect to the internet. The auto-connect switch is turned on but it doesn't make any difference. I've never had a problem connecting these devices before with my Actiontec M1424WR router.
