brossj,
Sorry to be so harsh in my first post. If it sounded like I was trying to scare you, well, I was. (I literally cringed when I saw your post.) Aside from violating basic network security practices, certain industries (Financial, Health, Insurance, etc.) have specialized rules that they MUST follow to safeguard sensitive data and remain in compliance with relevant Federal and State agencies. Your IT department at work is familiar with such rules. Putting your own wi-fi access point onto a company network is akin to installing your own door into the building. A door that either does not lock or for which your boss does not have the key.

That having been said, I'm gonna throw you a bone. If you really want to connect your IT to the Internet from work you have two options-

1. Bluetooth via PC- It is generally not considered a security problem to tether a handheld device/PDA to the Internet through your PC via bluetooth. The reason for this is that bluetooth travels only a few feet, whereas wi-fi goes much much further. Definitely ASK your IT department for permission/help first. But chances are it won't be a problem and that at least one of them owns an Internet Tablet and can assist you.

2. If you are allowed to plug in your own laptop via Ethernet you can get a USB ethernet adapter and do the same with your tablet. However, only some adapters will work at all and the required drivers are not included by default. So #1 is probably your best bet.

hope this helps,
