Think carefully before buying the Linksys XAC1900. It’s a great performer, and the software is really good, but it lacks VDSL support yet still costs more than other routers.
Premium pricing without premium performance is a touch disappointing, when other Linksys routers have performed so well.
The Linksys XAC1900 is a convenient and compact way to get the full complement of a modem and a high-end router. For most users, though, combining a standalone router with a free router from their ISP is likely to be the cheaper option.
