My laptop has two WAN interfaces. One is wireless LAN and other one is wire LAN. Is it possible to double WAN speed with that two WAN interfaces? If yes, how to do that? I have heard that Load balance software is needed. Is that correct? If yes, please recommend me which software is suitable and easy to use?
I assume you are trying to increase your downloading speeds by combining both your internet connection and possibly a neighbors via unprotected wireless. Load balancing will allow more users/applications to have higher speeds but it will not combine the speeds of both lines. If you have two 1mb connections you will not get a 2mb connection by load balancing them, you will allow two users/applications to run at 1mb simultaneously.
