Router working for some computers and not others

Specs: Windows Vista
I just installed a new router (D-Link DIR-632). I am using all 8 ports on the back - these ethernet connections go to either a switch to 1 or more computers or to wireless hubs. Some "hardwired" computers work, others do not. Some wireless computers work, others do not. I have approx. 20 computers total using the feed off this router. Any suggestions to get internet to all computers or what may be happening that it works on some and not on others. There is also no consistency on the operating systems - I have vista, Windows XP, Windows 7, and Windows 8 and it works on all 4 operating systems just not on all computers. Thanks for your help.

The following excerpts are from the manual:

Computer with the following: • Windows®, Macintosh, or Linux-based operating system • An installed Ethernet adapter Browser Requirements: • Internet Explorer 6.0 or higher • Mozilla Firefox 3.0 or higher • Safari 3.0 or higher • Google Chrome 2.0 or higher
Windows® Users: Make sure you have the latest version of Java installed. Visit to download the latest version.
Computer with the following: • Windows® 7/Vista®/XP (Service Pack 2 or higher) • An installed Ethernet adapter
• CD-ROM drive

Before you Begin

In before you begin it states you must use the last computer connected to configure the router and you must use a wired connection with that computer.

I would compare a working machine to a non-working one.

Open an elevated command window: Start menu, type CMD in search box, right-click on CMD and Run as administrator.

In the command window type: ipconfig /all >%userprofile%\desktop\ipconfig.txt (You can copy then right-click in the command window to paste)

That will place a text file on your desktop. Do this on the two machines and compare, or paste the results here and someone hopefully can interpret them.
