What might be the issue?

[jamesjohnson]

I'm dealing with an issue where my Raspberry Pi 3 Model B was damaged, and I've since substituted it with another identical unit from my spares. However, this replacement seems to have a problem with its network card not being recognized (when I run ifconfig, it only shows the loopback address and no eth0). I'm currently using WTware version 5.6.24. Can anyone shed some light on what might be the issue?

Identical unit will not work if it's Model B+. B+ has another network card and released later than 5.6.24 so unsupported by 5.6.24.
