I would stay away from Linksys routers, particularly the EA series. Do a search on “Cisco Linksys forced firmware upgrade” to find some gory details on a company WAY overstepping their bounds. I just returned my EA4500 and replaced with an Asus.
It gets worse. After reading several tech articles on this incident it appears that Cisco is still reserving the right to update router firmware remotely, even if auto-updates are turned off, if they deem it is necessary. Scary.
