Yeah, I basically ordered one with an rtl8811au chip. Works fine so far. I'm able to get up to 116 Mbits in AC mode, 109 in N mode from short distance. I guess a miniPCIe card will do even better.

Thanks for your reply. This makes some things more clear to me. For the time being, I've ordered a USB-based WiFi AC speed card for testing purposes which works great so far. I'm just wondering why other cards may work while these ath10k cards have issues. As far as I know both the Espressobin and the Clearfog uses the Marvell u-boot from Github. However, I'm not really willing to flash a custom-built u-boot version (and probably find a way to incorporate changes to get it running) because some people have reported to brick their device when flashing a custom-built u-boot firmware. I'm absolutely new to this embedded stuff and have dig into this to figure out how to work with it.

Hi there, I've recently ordered a miniPCIe Wifi adapter for the Espressobin, so it can act as WiFi Access Point. The device does recognise the card (using `pci` in u-boot lists the device), but the kernel doesn't. All I can see is the following in dmesg output: [ 2.969072] advk-pcie d0070000.pcie: link never came up [ 2.974496] advk-pcie d0070000.pcie: PCI host bridge to bus 0000:00 [ 2.980995] pci_bus 0000:00: root bus resource [bus 00-ff] [ 2.986325] pci_bus 0000:00: root bus resource [mem 0xe8000000-0xe8ffffff] [ 2.993793] pci_bus 0000:00: root bus resource [io 0x0000-0xffff] (bus address [0xe9000000-0xe9) [ 4.435260] advk-pcie d0070000.pcie: Posted PIO Response Status: CA, 0xe00 @ 0x0 u-boot is at its latest version from the Espressobin website. The affected Wifi card is a Compex WLE600VX which should work with the ath10k driver. What options do I have? GlobalScale (the manufacturer of the Espressobin board) recommended to buy their miniPCIe Wifi module, which needs to be shipped from overseas which I want to avoid if possible. Thanks for any hints.
