At this point, I'm just brainstorming, and would like some input. (I hope this thread is in the right place)
I'm trying to find a setup to connect to free wifi hotspots that are far away, and share that connection to a group of devices locally. For example, this solution may be useful in a boat or an RV, when you're not particularly close to a free access point.
There are commercial solutions like the Rogue Wave however, this doesn't do anything to authenticate through the Terms of Service (TOS) pages that are frequently used at free access points.
This is what brings me to using Android. There are Android apps which automate the process of accepting the terms of service. My favorite right now is WebWifiLogin (I'm familiar with the security risks involved in using public wifi; and may also have the Android device to also establish a VPN connection when doing this.) (I can't find an equivalent macro-authentication solution that will run on a PC, which would make this much easier.)
So here's my proposed solution:
1. Start with a powerful omnidirectional wifi antenna (Possibly add an in-line amp if needed. Also perhaps a directional antenna may be better for non-mobile use.)
2. Connect the antenna to any Android device that supports an external Wifi antenna. I found several Android TV devices which should work. Like This, or possibly this.
3. Set up some kind of local access point/bridge. One option may be to use fqrouter2 which supposedly uses the same Wifi radio for the local WLAN, while it also connects to the remote one. Another option may be to USB or Ethernet tether to a DD-WRT Router.
The Android device has a range to connect to a free hotspot up to a mile or two away, then automatically accepts the TOS using the WebWifiLogin app, and shares that connection locally to a handful of devices.
So am I crazy? Is this too complex to work correctly? Is there a simpler solution that I'm missing?
