We don’t recommend it because it’s frequently implicated/isolated as the problem in support incidents. I’m not sure whether that is due to a bad WiFi implementation or a weak CPU–we are usually dealing with these problems remotely, without the ability to do detailed analysis.
Apple has pulled out of that business…so the products also don’t get good ongoing support, and the last one was released quite a while ago, so they generally aren’t up to the performance of something more modern.
I don’t necessarily hold Broadcom in such high esteem-for a long time they were making chips that would misbehave as soon as a non-trivial amount of multicast UDP traffic was present, and they were totally unhelpful/unresponsive to the issue. I avoided them for years. At the time, the Atheros chips were far superior. Same time period as when Apple was designing their routers, btw, though I’m not sure if they used one of the bad ones or not.
