Apple Airport Extreme 802.11G

OKay so I have an Apple Express airport 802.11G yeah it's old, but I haven't had any issues with it until today. My dog knocked it off the desk and before I could save it, the airport hit the ground.
Picking it up I put i back in its place and then got on my iMac the internet connection is fine. But on other Devices( i.e my lap tops Windows and MAc, Phones (iphones and Androids) it isn;t connecting well at all. The Connection will be there and then go away.) But the connection to my Game consuls seems to be fine. ( Tested this buy playing netflix movies/shows on them).
I have already tired unplugging it and plugging it back in many times but things just kept on being as I stated before. I wanted to know if anyone out their can help me. And if you can please do, cause this is getting frustrating.

What I have found that If I take my phone close to the airport I will have a strong connection but If I go into the other room that is like 10 feet from the airport the connection disappears.
Any ideas?

You may have only a few ports damaged or is it totally wireless? If it is Ethernet you can swap ports to see which is damaged, wireless I would be looking at hair line fractures in the circuitry, either way a new one is required. Computers, animals and fluids don't mix generally
