I am having trouble connecting lap tops to my WIFI. I have a Linksys EA4500 router that worked fine when i got it but now laptops cannot find my router. I've had a few different laptops try and connect to the router but none of them can find it. i can connect tablets, phones and games systems no problems. I've restored my laptop to an earlier date and uninstalled and re-installed my laptops wifi driver but it hasn't fixed the issue. I also reset and set up my router again and that hasn't fixed it. Any helps appreciated, Thanks!
