There are lots of news articles and discussions about the 'KRACK' attack vulnerability affecting WiFi client devices.
In summary, this affects WPA2 (and WPA3) (as well as being an additional insecurity with TKIP) And is actually a bug in the WiFi spec - ie the design wasn't thought out properly. So any implementation which follows the spec is vulnerable. There is more technical information about this in the links below.From an customer of AAISP point of view, we do sell DSL routers with WiFI as well as WiFi access points but, this is a vulnerability in WiFi clients rather than the routers themselves.
Generally, the fix for this vulnerability is on the client side - ie the computer or mobile device connecting to a WiFi network, and so customers should look for software updates for their devices and operating systems. There are links below regarding devices we are involved with which contain further information.
We'll add further information to this post as we receive it.
