I know there have been various posts for older macbooks with weak wifi but I have not seen any postings for solutions or causes. I have a Macbook 2.0 Core Duo and use a D-Link 802.11g router. I've had the Macbook for 3 years and have been using this router for a year without any wifi issues. Then last week it the wifi reception suddenly cuts out and I have to put the computer literally next to the router for it to get any reception. I believe the problem might be with the Airport card, and I've been looking at different options to replace it. Has anyone tried replacing their Airport card using an ifixit kit? I'm worried it might be too difficult to install on my own. The other solution I thought about trying is using a USB wifi card/dongle. The only problem is I'm a little overwhelmed with the choices available and not sure which ones would compatible for basic use on my macbook. If anyone can suggest a USB wifi solution or any reasonable solution for my wifi issues I would appreciate it.
