Best Answer: From my understanding "anything is possible." Someone on the internet could very feasibly connect to your Wired network using your machine as an entry point. I would say the risks are extremely small, however. Employ software or hardware firewalls between the networks and disconnect from the internet whenever possible by unplugging or turning off your wireless adapter. If the information is extremely sensitive or valuable on your wired network, I wouldn't recommend connecting to the internet at all. Keep in mind that a strong motivation would be required from a Hacker's standpoint to try and surmount your security or single out your network as a target worth his/her time.

Re:For general Broadband Internet connection (Wired and Wireless) you need both Hardware and software Firewall as well as "Cleaning Tool".

For the Wireless Component you need to set the decurity settings of the Wireelss part of the network.

Re:For wireless, you need to be using WPA, either with TKIP or AES (preferred). You can use WEP, just make sure that if you do you use 128 bit, and that you change the key on a regular basis. Also use MAC filtering. Turning SSID broadcast off can be a good thing, but if you're using encryption then it doesnt really matter if you do. Someone skilled enough to crack WEP keys is skilled enough to find your network even if SSID broadcasting is disabled. If you want to get extreme and you have the ability to control the power output on your radio, you can turn the power down to cover only the range you need wireless access in. No point in broadcasting the signal half way down the street if you only need it in a couple of rooms. If it's a G access point, and you've got all G clients, then you should disable access to B clients…vice versa if it's a B access point.
As far as ports go, every port coming into the network should be disabled to the outside. Firewalls do this. Only open up ports you need, such as for a web server, or for games. Only open them up to a specific host inside your network.

Re:Tell us what router you have. Some companys have been installing backdoors that need to be disabled.

Re:At the least on wireless, use WEP and turn off SSID broadcast. Try 64 bit WEP first and get a feel for performance. Then try 128 bit and see if you notice the performance degradation. Closing ports depends on what you want to do online.
