There are three primary choices for Tablet connectivity. These are: 1. WiFi wireless 2. 3G connectivity if your tablet has a SIM slot 3. Hand-net (You remove and insert your micro-SD card from your tablet to your PC and vice-versa) There are other options which for you. Some work fine. Others have issues. These are: 1. Direct wired network connection. There are many tablets which have the VIA 8505 chipset also include a Mini-Dock. This mini-Dock has a 10-100 network connection. Note: Some individuals have had problems with the wired network connection. I am one of them. I had to manually configure my network connection for it to work. 2. Direct Tethering to your 3G Phone: Some but not many phones allow the phone to be used as a 3G modem via USB hosting. I have yet to see it work on an Android Tablet. But it should be possible. 3. 3G Modem insertion.This is using the 3G Modems that would go on your PC USB port plugged into your Tablet USB. This sounds like it could work. But I have played around with my 3G modem and no luck thus far. It is recognized by my tablet. But the tab does not seem to make that final network connection. You may have better luck. NOTE: Using a 3G Modem card on a Tablet really, really sucks the battery on your tablet. 4. IPhone MyWi or Similar AdHoc 3G applications. What these applications do is turn your 3G phone into an Adhoc WiFi access point. This thread describes how to set your tablet up for AdHoc WiFi. Remember AdHoc connectivity is not the same as a true Access point. It is more like a one to one conversation. The applications work, but do not expect robust speed. And the other ad hoc phone Access point may not have a great wireless antenna, so you might have a range of 1 Meter. 5. MiFi Routers or MiFi capable phones. This is by far the best solution for the Android Tablet user who wants connectivity. MiFi is pretty neat and offered in both dedicated router or built into a phone. I started using MiFi for my Tablet and it works great.Mine is a Novatel like what I have shown as a link. MiFi is NOT offered everywhere in the world so you might want to look at adhoc applications like a MyWi. The Droid X offers the mobile Wifi Hotspot. This is another option Best of luck on any of these.
