The ZBT WG3526 has a mini PCIe interface, which can be used with a 3G/4G module as advertised by the manufacturer.
I would like to use the mini PCIe interface with a WiFi module. I am using a Sparklan WPEA-128N which is Qualcomm Atheros QCA9880 based (ath9k driver).
However, when I plug the WiFi module, OpenWRT doesn't seem to see the WiFi module.
The only difference I could observe in dmesg with the WiFi module plugged-in are the following lines:
[ 1.980000] pci 0000:00:00.0: bridge configuration invalid ([bus 00-00]), reconfiguring
[ 1.990000] pci 0000:00:01.0: bridge configuration invalid ([bus 00-00]), reconfiguring
[ 1.990000] pci 0000:00:02.0: bridge configuration invalid ([bus 00-00]), reconfiguring
The output of lspci:
00:00.0 Class 0604: 0e8d:0801 pcieport
00:01.0 Class 0604: 0e8d:0801 pcieport
00:02.0 Class 0604: 0e8d:0801 pcieport
01:00.0 Class 0280: 14c3:7603 mt7603e
02:00.0 Class 0280: 14c3:7662 mt76x2e
03:00.0 Class 0101: 1b21:0611
Anyone can help ?
