Makes your wireless card a full modem T. Ceglarek October 28, 2007
I use this router with a pcmciaa Sierra aircard on the Cingular/ATT network. I'm very pleased it extended the capabilities of the card from simply allowing access from my lap top to using it as my overall internet connection at home. Speed is sufficient to play Final Fantasy on the Xbox and even hook up the Vonage router to make phone calls. It's certainly not as fast as my old wired dsl connection but that is not the router's fault just the fact of the cingular/att wireless network. For me this router saves me 50 bucks a month by allowing me to drop my wired connection. I grab my aircard when I leave for work in the morning and then after work and weekends just leave it in the DLink router for around the house always on internet connection. Great router I bet it would be a big seller if more people knew about it.

Check you Service provider TechsysT June 16, 2008
The router worked as promoted, but I purchased it to host a internet camera at a remote site. At&t does not allow hosting on their broadband cards, so the service provider was the problem. Its in their contract. Check your service provider details for their cards before purchasing. Amazon was GREAT, they allowed me to return the product. I will use Amazon for all my purchased for now on.

D-LINK Sucks ! Brazuca January 20, 2009
I bought this router to use with a 3G modem. I did a firmware upgrade and it worked for 15 minutes and after that it keeps rebooting after each 30 seconds !!! No way to buy D-Link again !
