Dell at least sold the XPS 13 9310 with 32 GB RAM in Germany (https://www.dell.com/de-de/shop/laptops/neu-xps-13/spd/xps-13-9310-laptop/cn93212) with the QCA6390 device. With around 2300 EUR, this offer is still expensive but it's less than the 4000. In the delivery notes they called the Wi-Fi card "Killer Wi-Fi 6 AX500-DBS (2 x 2)" (part number 555-BFPF) but in the current version of the linked listing this is now "Killer Wifi 7 AX500". I'm not sure if the "DBS" part has anything to say. > > I had the same problem as well back in the days, for me enabling > CONFIG_IRQ_REMAP helped.

I noticed that the Wi-Fi card is behind a PCI bridge which is also disabled, could this be a problem? 00:1c.0 PCI bridge: Intel Corporation Device a0b8 (rev 20) (prog-if 00 [Normal decode]) Flags: bus master, fast devsel, latency 0, IRQ 123 Bus: primary=00, secondary=56, subordinate=56, sec-latency=0 I/O behind bridge: [disabled] Memory behind bridge: 8c300000-8c3fffff [size=1M] Prefetchable memory behind bridge: [disabled] Capabilities: [40] Express Root Port (Slot+), MSI 00 Capabilities: [80] MSI: Enable+ Count=1/1 Maskable- 64bit- Capabilities: [90] Subsystem: Dell Device 0991 Capabilities: [a0] Power Management version 3 Capabilities: [100] Advanced Error Reporting Capabilities: [220] Access Control Services Capabilities: [150] Precision Time Measurement Capabilities: [200] L1 PM Substates Capabilities: [a00] Downstream Port Containment Kernel driver in use: pcieport -- ath11k mailing list ath11k@lists.infradead.org http://lists.infradead.org/mailman/listinfo/ath11k
