I'm looking for a router with the following specifications:
- Wireless N
- OpenVPN client support (to connect to an openvpn access server)
- Built in 3G/4G Modem with SIM slot (3G: 850MHz/2100MHz, 4G: 700MHz/1800Mhz)
I have found Industrial M2M Routers such as the Netcomm NTC-140W matching my needs however I don't wish to spend as much as $800.
