Yikes
I have had an ASUS router since January, which has been working really well. When I set it up, I tried to be a good tech consumer and clicked the button looking for any firmware updates. It said none were available. I also clicked the "Check Signature" button, which cryptically (no pun intended) returns a worrying message "Signature update completely".
After reading this article I went to the ASUS web site -- something I should have done on the first day -- and discovered there had been FOUR firmware updates released since the August 2015 date when the out of the box firmware had been released. It's good ASUS is releasing updates (and giving credit to those contributing security fixes). But how hard is it to wire that stupid button to a working updater service?
FWIW, my previous WiFi router was an all-in-one combined with a cable modem. In the US, that means that ZERO firmware updates can be installed by the end user. Any updates have to be pushed from my cable company. Good luck to anyone relying on that.
