I'm hoping someone can give me some good detailed instructions and advise on the proper way to set up a network. I have no formal training in the IT industry but I know considerably more than the average user as I am self taught. I am a veteran who has started volunteering a a veterans outreach center to help other fellow vets. They need me to set up a network for them. They have very little money to spend so I have to try and make do with what equipment that has been donated to them. (I'm trying to get newer equipment donated). They have 3 PCs that are 10-15 years old running Pentium 3 processors (886 Mhz to 1.2 Ghz), very little RAM and small hard drives. There is a cable modem with a Cisco Lynksis WRT110 wireless router. 2 printers. 1 PC is hard wired into the wireless router as is both printers. The other 2 PCs are using wireless G USB adapters. The 2 PCs with the wireless G adapters get very weak signal so I'm thinking of get 2 wireless N adapters. I need to set up me as the administrator and everyone else as users with limited access. I also need to set up a share folder, allow them internet access (but with restricted site access). Can anyone out there help me with this or direct me to a good site that would help me? Me and my fellow veterans thank you ahead of time.
