Do I need a new Airport Extreme card?

I recently bought a used MacBook Pro. I can log onto my home wifi when I am within 8 ft. of the router, but if I walk to the next room I lose signal. Another Macbook we have has no connection loss even at greater distances.

Do I have a bad Airport Extreme card?

I also have a problem using Ancestry.com on the two Macs I have running Snow Leopard. Other versions of OS X have no problem. I tried to install a newer version and I think that my MacBoo Pro 1,1 cannot upgrade because it is not a CoreDuo 2, only a Core Duo. Any suggestions?

Is this a good question?

Sadly, there is no answer for your application problem we can offer you here. The maker of the App will need to help you. I suspect they don't support the older hardware (OS-X) with their latest version of the App. You'll need to use your newer system.

As to your AirPort card problem. It sounds like you have an antenna issue Vs a bad card if it is able to work at all.

What I would recommend is downloading from the App Store a good WiFi signal monitoring app and install it on both your good & bad connecting MacBook systems. Then compare what frequency and noise to signal ratio. Are they the same? You may be connecting on different frequency bands (2.4 Vs 5.0 GHz).

  • The 5.0 GHz band does not go though walls as well as the 2.4 GHz. But the 5.0 GHz is able to transmit at a faster rate.
  • You maybe sitting on an area of the band that others are also on near you which also effects throughput.

Consider altering your WiFi Router (AP) so it's on a different area in the band as well as label your routers AP's so if you have a dual WiFi unit each of the bands are uniquely ID'd. I add the number of the band to the AP name as an example: ACME2 & ACME5. That way I know which I've connected to.

Your answer sounds logical and seems to be good news. I do not know how to change the router settings. I think you have put me onto the right track. I will look into it further. Thank you for your help.
