wg1608 with RM520N-GLAP possible?

[MrEdLu]

I purchased an RM520N-GL(AP) variant before I knew the difference between AA and AP.

• RM520N-GLAA supports USB and PCIe.
• RM520N-GLAP supports only PCIe.

When I plugged it into my WG1608, nothing happened. It doesn't detect the board. Is there any way to get RM520N-GLAP working in my WG1608 16m? I'll assume that I need some PCIe driver. Has anyone gone down this rabbit hole?

Did you solve this, I am in the same boat

No, wg1608's m.2 slot is USB only. I went as far as installing openwrt on WG1608 and running the lspci command. Wg1608 does not see the RM520N-GLAP. Dead end here.

Having this RM520N-GLAP that I can't return, I tried ordering a desktop PCIe to m2 card and loading Ubuntu on my PC. It sees the PCI modem but I get this error during ubuntu boot up

Once booted up, running a lspci shows

I have also looked for Windows PCI drivers and couldn't find one. I can't seem to get any further with my RM520N-GLAP. I would appreciate any chime in on getting this working any way possible.

BTW, The PCIe to m2 desktop card that I order is "M.2 B Key USB3.0 & PCIe Dual Bus Interface 5G WWAN Card Adapter Support 3042/3052 m2 3G/4G/5G Module for NANO SIM Card" https://www.aliexpress.us/item/3256805348610910.html
