Are there any Mini-PCIe cards supporting dual-band 802.11ac known to work with the RBM33G? It looks like Microtec's options for Wifi here are either 2.4 or 5G not both. Yes, I know the RBM33G has two slots but unless a modem can be but into the M.2 slot and still the other SIM slots. the second is going to be used by an LTE module. I know Intel and Broadcom chipsets don't work well but I'm a bit confused on which Atheros cards may solve this.
Thanks in advance.
