I've been encountered Wi-Fi problems with my MacBook Pro 15" 2011 (early). After browsing different forums I still have not found a proper answer on what can be done to fix the problem nor troubleshoot.
The Wi-Fi on the laptop is only connecting in certain rooms. For example, in my bedroom, the wifi can not be found on the MacBook (but the wifi can be found on my LG Nexus 4 as well as Lenovo laptop - we also tried with an old MacBook from 2009). So it is certainly something wrong on this specific laptop. I am able to get connection in a room close to the router, but then only if the screen is tilted. So - for me, it seems like its some hardware problem (I've read that the Wi-Fi card is somewhere close to the screen, so it might be some cable issues). When using an ethernet cable, it works perfectly fine.
My question to you guys is if there is someone else who have had the same problem? And if so, if you were able to solve it. Im currently thinking of making a clean reinstall to see if it makes a difference, but due to my so far troubleshooting, I am afraid its a hardware problem.
Is there anyone out there who have had the same problem and actually solved it? And if so, how did you do it?
Is it just not connecting to WiFi at all in certain rooms, or is it connecting to a different WIFI (perhaps your neighbour's signal strength is stronger in certain rooms than others and is interfering with your connection there?)
Maybe a WiFi extender would solve your problem?
It just seems odd that your Mac connects in some places but not others, to me that suggests that it's not a hardware fault, but an issue with the WiFi signal being strong enough.
