To get as close to the latest kernel, etc, I tried the daily build of 17.10 server. Its kernel 4.12.0-13-generic #14. It behaves like the 16.04.3 and 17.04 desktop versions. That is, it half works. You can see the wlan0 device, but you can't scan and find any stations. It also has a very funny lag, as if the system is doing lots of extra processing and can't keep up. The syslog is filled with "rsi_91x: rsi_interrupt_handler: Failed to Read Intr Status Register" messages.
I suspect you've broken the RSI 91x driver or RSI SDIO driver. I suspect they've been broken for some time. The last working version for me was 16.04.1. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1715741 Title: Wi-Fi broken in 16.04.3 and later on Dell Edge 3003 Status in linux package in Ubuntu: Incomplete Bug description: The built-in Wi-Fi on the Dell Edge 3003 is not working.
