The tplink doesn't need to use the Ethernet port except for initial configuration, it is a wifi router, but it will not solve your Internet access issue. If you have a smartphone and your data plan allows it, any smartphone can create a mobile hotspot for 5 or more devices. Alternatives are to biy a hotspot device from your mobile carrier (often called MyFi or MiFi devivlces) or to the Internet through your phone via USB and use the software I linked to allow the EZ-B to connect to the tablet.

@Richard.

No worries.

@Alan.

So it sounds like the mobile router I linked to in post#8 (which I believe is a MyFi device) will do the trick then. I just wanted to be sure before I paid out for something, or started a 12 month contract on a device that wouldn't do what I wanted to. I kind of like this approach as it can easily be installed in the robot and will maximise signal strength (depending on cellular coverage of course).

Thanks guys.

That device does not have a built in 3G/4G modem. It looks like you need a USB 3G/4G modem to connect to it. If you are doing that, might as well get one from your carrier with the WiFi router already built in rather than cobbling together parts from multiple vendors.

@Alan.

See, I told you I didn't know what I was talking about, lol. Seriously though, good catch and I see what you mean now. I'm guessing this is more like what I should be using...

I thought you could insert a SIM card in the other one, but looking over the specs again I see that this is not the case.

Thanks again.

Yup, that's the kind of device you need.

Alan

Lovely. Thanks.
