Troubles with Wi-Fi connection

Dear all,

I am facing troubles with Wi-Fi connection. My 13" MacBook Pro is almost 5 years old (Mid 2012) 2.9GHz.

The Wi-Fi coverage is very poor. I have to be very close to the Wi-Fi router in order to connect to internet (5 meters max).

All the software is up to date.

Would you please tell me if the problem is related to software or hardware?

If hardware, is it related to Antenna or Modem?

THANK YOU

I doubt you have a AirPort card problem, but the antenna cables or the ribbon cable could be damaged.

I would start off trying some diagnostic tools to see what they tell you. I would get this app from the Apple Store: WiFi Exporer Which I find is a great tool to have. Using it you could be able to see the different WiFi bands your router's Access Point (AP) is offering out. To isolate out which band your system is connecting you'll want to alter the AP names so the 2.4 GHz band is called something like ACME_2-4 and the 5.0 GHz band is called ACME_5-0. That way you can choose which band to use from your Mac. Now once you have altered the naming reconnect your Mac to each one to see which antenna connection is failing or if both are bad.

Review this IFIXIT guide: MacBook Pro 13" Unibody Mid 2012 AirPort/Bluetooth Board Replacement jump down to Step 7 inspecting the antenna connections are any loose or the wires not cleanly fitted in the slots? If they look OK, then you may want to try replacing the ribbon cable as shown in Step 5 MacBook Pro 13" Unibody Airport Card Flex Cable - Apple P/N 922-9780. If the antenna cables are damaged you'll need to follow this IFIXIT guide to get the display off to replace the antenna unit: MacBook Pro 13" Unibody Mid 2012 Display Replacement so you can slide off the clutch cover (slides to the side then pops off) and you'll need this part: MacBook Pro Unibody Airport Antenna - Apple P/N 922-8782
