This week, Google Chromecast Audio devices were shown to cause certain routers to crash or boot-loop, but now there's a workaround.
BT HomeHub routers seemed to be most affected by the issue, which also involves the Chromecasts themselves crashing or boot-looping, and in some cases seems to occur with other Chromecasts such as the Chromecast Ultra.
The problem seems to have stemmed from a firmware update, with a member of the Google Cast Community Team saying on the support forums that it is down to "a Chromecast Audio running firmware 1.21.72444 on select wifi routers."

Now Google has advised users affected by the problem to find a working router which they can use to connect the Chromecast in order to update to the latest firmware.
Once connected to another router, Chromecast users should use the Google Home app Preview Program option to download the version 1.22.77272 firmware update which comes with a bug fix.
Once downloaded and installed, the update should ensure Chromecast Audio devices work with the BT routers as normal.
It's not an ideal fix, as it requires a working router, which is exactly the problem in the first place, but another Google representative said on the forums that the company is 'looking at other options'.
Plus Net One routers are also said to be affected by the boot-loop issue, and for the time being, the 'find a router that works' advice remains in place for them, too.
We'll update you as soon as Google announces any other fixes for the problem, but for now, it looks like you'll have to dig out an old router or ask your neighbour nicely if you can use theirs.
