Please forgive if this is "too basic" or otherwise beat to death elsewhere, but I just cannot seem to find the answers I need no matter how or where I look!
In short, I would like to know how to add an external yagi antenna to my existing home wifi network, and use that antenna to access a nearby public hotspot as an "alternate" along with my current internet gateway.
I already have an antenna and enough LMR400 to get that part setup, but I'm not sure what additional hardware I will need to do this.
My current home network consists of a primary XP Pro desktop computer wired to a LAN port on a WRT54G router (now running Tomato v1.28). The router's WAN port is wired to a cable modem. Then, 2 additional desktops, a laptop, an iphone 4, and an ipad2 all connect wirelessly to the WRT54G for ICS and network shares.
So far this setup is running well for me with mostly decent (but sometimes varying) signal strength and througput in most areas of the house.
However, my town has recently partnered with Google to provide several free hotspots in our area, and one of these new hotspots has a freshly installed access antenna that is within about 200 yards of my backyard (perfectly clear line-of-sight, too!).
Well... this "free" internet access opportunity is a bit hard to just ignore; and, if nothing else, I think that getting setup for access to the hotspot as at least a "back-up" would be a wise move.
So...with that said...I would greatly appreciate any help the group can provide to answer these questions:
1. What equipment do I need to establish a connection to the hotspot through my yagi antenna?
2. What equipment do I need to tie the hotspot connection (from the yagi antenna) to my existing network, and make the hotspot available as an alternate gateway to the internet?
3. How do I go about configuring the hardware/software required to do this?
(BTW - I also have a currently unused 3Com wireless AP available, if that could help me somehow).
Many Thanks in advance to all who offer help!!!!
