Nexaira Business Class 3G/4G Router (BC2) - Firmware 1.2.4.8
[R-SI-NEX-BC-B209]

Absolutely awesome router. Easy setup, and tethers to both my iPhone 3GS and 4 flawlessly. I was able to eliminate my home ISP and save some money by using my iPhone as my primary ISP. I don't stream video, so the ATT 4 gb cap is no problem. I was able to change my SSID, setup WPA2 encryption using the AES algorithm, and enable mac address filtering with little effort. Although, the mac addresses have to be entered in the format two digits, colon, two digits, colon, etc., and it took me awhile to figure that out. Also I miss being able to label the mac addresses so I know which is which, but I can live with that. The documentation that comes with the router is weak on instruction, but other than that, it is a great piece of equipment. The best part is that I can use my wireless printer once again and print from the internet via my iPhone.
