The original network card in my MacBook Pro Early 2011 13” does not seem to have great network range. I have tried reseating the connectors on the network board with no success. Any help would be appreciated.
If you have a second mac system in the same series you could compare the signal strength. Click on the WiFi menu icon while pressing the Option key it will allow you to see the signal levels and version info. You can also run WiFi diagnostics as well. With a second Mac you can do a side by side comparison.
