Can someone please offer some suggestions with this network problem running under Arch 64bit.
In the past I have installed Arch and derivatives and using a Broadcom 4360 chipset adaptor. This uses the broadcom-wl driver. In the past as long as the driver was installed it just worked.

In my current installation I used an Intel card in an adaptor but for some reason an antenna got broke off so I got my old card out and installed it and loaded the driver but the card is not recognised.
lapci shows it is installed
iplink only finds the Ethernet card.

I don’t know where to go from here.

Thanks, Robert...

Fixed the problem. It turned out that the LTS kernal and the broardcom-wl kernal is not compatible. As soon as I changed to kernal 4.11.5-1-ARCH it worked. That leaves some discussion elsewhere about the kernals.

Whoopie! Thanks for the update and solution. My guesses would have maybe gotten there after a while.

Kernels do that stuff.
