Default Can i share my 3G with my router?

I have and use a rooted Droid. I share the 3g connection with my laptop using the Barnacle app. My question is... can I set up my Netgear WNDR3700 to accept that ad hoc beacon from my droid and share the 3g connection over the rest of my network through the router? In other words, can I share the 3G connection from my droid over my whole network through my WNDR3700? If so, how?

I know some routers can act as repeaters, but I don't think you can repeat an ad-hoc signal. Maybe if the Droid could broadcast infrastructure mode (I think some phones can). I'm not sure about this though.

A quick read of the specs for the WNDR3700 didn't reveal a WiFi repeater ability. So short answer is NO, not with your current set up.
There are only a handful of WiFi routers that do the repeating. The ones I know of and use are:CradlePoint CTR35 & ASUS WL-330gE,
The remaining are:
Engenius ETR9330
Dlink DAP-1350
Netgear WGR101
Good luck!

Default Repeating an ad-hoc signal

Hello, this is only my second post -- but thought I would share my success story in accomplishing this (albeit with slightly different parameters)...

I was tasked with setting up a wire-FREE connection for where I work (i.e. no wires between rooms, thus no switches & ethernet connections, also no ISP could wire the building -- strictly no wires). I had to make it work given a Sprint EVO 4g and some old B repeaters (that I ended up not being able to use). These old repeaters obviously did NOT have the level of depth required for this, but having used an alternate router firmware called DD-WRT (read about it HERE) I thought I might be able to set it up -- but you will need a newer supported router....

Here's a GENERAL guide to how I did it (from memory, as I don't have access to the hardware at this moment -- will check the exact settings if there is any interest):

**Please note that you must have DD-WRT successfully installed on a supported router to do any of these steps.

1. Set up the router with DD-WRT loaded fresh directly next to the phone in wireless tether mode.
2. Set up router as a wireless bridge, then go into the wireless settings and try to connect the router to the ad-hoc connection (you SHOULD be able to see it, if not perhaps the hardware of the droid differs from the EVO 4G and this wont work).
3. Once connected, in THEORY the router should repeat the wireless signal from the phone no problem. I ran into a problem at this step, however, because the router would not repeat the signal at all -- big problem! I had almost given up but then I saw the setting for a virtual interface.....
4. Create a virtual interface, then link it to the repeated wireless connection (this is where my memory is the fuzziest about the setup, unfortunately -- I don't recall there being any other steps though). Viola! The signal repeated strongly, though there was the minor annoyance of there being two SSIDs (or three if you are very close to the phone). I have NO idea why the virtual interface makes any difference, but it did for me.

Other than those minor annoyances, it worked! Speeds aren't fast enough for the multiple PCs I hooked it up to, but in a tight situation it works well enough.

Hope that helps someone out there!
