@zsojka - the easiest way to get lspci installed, assuming you have WAN, is to go to the console, and enter the following commands:
opkg update
opkg install pciutils
afterward you’ll be able to run lspci -v to verify what cards are detected.
I’m having the same issues as you and I think it’s a firmware issue. Sad that we’re left stranded after paying good money and waiting so long for this device
