Replying by phone; please forgive the top-posting (and potential typos)
that result from that.
Would it be possible to have *two* PCIe Mini Card slots, say one for WiFi
and one for 4g/LTE?
That would be awesome. Mom hates cables, and I mostly agree with her on
that... so look much easier, with the router in the front hall, to run WiFi
rather than Ethernet to the kitchen table, two rooms and ~30ft away...
