Building a redundant router setup with Open Source Software (part 2)

In part 1 I went over the basics of failover. The problem with such a setup is that TCP connections will not survive a failover from ar0 to ar1, or vice versa. The main issue is that both routers have a different WAN IP, and in this case, seamless failover will never work.

Force wireless clients to connect to your 5GHz network

This is something that has been bothering me for a long time. I use the same SSID for both my 2.4GHz and 5GHz networks, so that clients can roam from one network to another. However, in this setup, the client decides what network it think will work best. And unfortunately, most clients just suck at making this decision.

Usually my clients end up connecting to the 2.4GHz network, unless they are in the same room as the AP. There's a simple explanation for this: the 2.4GHz network usually has a stronger signal strength, simply because the lower frequency penetrates walls easier.

U2F on Linux

Little over a year ago I ordered 2 Yubico U2F security keys, through the Github offer. When they arrrived, I was immediately annoyed by the fact that only Chrome (and Chromium) supported the U2F standard. At that time, my main browser, did not support U2F at all, and the feature request had been open for a year, with no real progress. Sigh.

I2S audio on XPS13 with Linux 4.5

While upgrading the Linux kernel on my XPS13, I noticed that I could no longer find the option to enable the ASoC driver that is needed when the sound card is running in I2S mode. The symbol (SND_SOC_INTEL_BROADWELL_MACH) was still there, but it didn't show up at the expected location. I also had all dependencies enabled, so I was a bit surprised it didn't show up.

After looking again, I noticed this in the dependencies:

DW_DMAC_CORE [=m]=y
