Hello
I am new to networking of computers. I already have the wireless set up on main computer. I want to setup second computer wireless, to use my connection to get on the internet, both computers are located in the same room. And be able to share printers on both computers.
The second had been setup at another location at one time/Daughters house, with her Qwest DSL Modem Wireless Gateway (Model #GT701-WG) .
I installed a new Trendnet TEW-443-PI wireless pci adapter with drivers, so that I could network the two pc's to use one internet connection here at my home.
Have not done anything with any of Qwest programs that were already on this pc.
Do I need to uninstall anything, from the 2nd computer?
How do I go about networking these? How to turn off firewalls?
How to find my IP addresses and all information necessary to get these going?
I know that prior trying to get help from Qwest, they pass me to MSN, then MSN passes me back to Qwest. Laugh! Qwest lists Tech Support Guy as a link for getting help with networking.
Please help
