Hello. I am having problems with both wifi connectivity and signal strength on my home network with the iPhone 5. On other wifi networks it seems fine, when brought in to the apple store it worked fine there and the hardware checked out okay. I reset the iPhone 5 and also its' network settings. I tried turning off encryption and making it an open network with no difference. Also I tried changing channels of the router, updating firmware, and resetting both the cable modem and router multiple times with no luck. I am using a Linksys WRT54G modem that seems perhaps around 5 years old at least. I asked on the Linksys forum and they suggested I buy a newer router. Do I have any other options? What router should I get? I don't want to pay a lot of money for it, up to $40 if I can help it. I would be happy buying a used router as long as it works well. Any and all suggestions will be appreciated. Thank you.
