Review on Wireless AirLink Enterprise Gateway Terminal Networking Products by Paul Lewis

Sierra Wireless Airlink ES450 for AT&T works as advertised. We installed an existing AT&T SIM card and got wireless Internet access through the Ethernet port. This product does what it is designed to do and does it well. This is NOT a wireless access point. This is a wireless modem for a fixed local area network. You'll need a little technical knowledge to set this up. There are also plenty of additional options to tweak if you like. The only gripe I have is that it seems you can set limits on data usage, but according to the documentation it doesn't prevent overflows. This was fine with me because I set limits on the router, but it can be a stumbling block for others. We all know how much AT&T charges for wireless data these days.
