Problems in the company's networking

[Karim Kahale]

Hi all, I am experiencing network problems.
The first laptop(windows 7 home 32-bit) : I am getting a yellow triangle when trying to connect to wireless internet or either ethernet through wireless lan. I only get internet working when I plug the lan cable directly to the internet port (NOT ON THE WIRELESS ROUTER PORTS).
The second and the third laptop : I tried to use usb to fast ethernet to connect them, first time it worked, the 2nd laptop which has a lan cable internet plugged in procured internet to the 3rd laptop and the internet sharing worked fine but after 15 minutes it was gone, I got the yellow triangle again.
Please can you help me as fast as you can as I am responsible of the tech stuff in this company !

Hello Karim,

Verify that you have enough Auto IPs assigned or DHCP Scope.

Bandwidth subscription plays a big role in the network if there are a few employees connecting to the internet.

Policy restrictions on websites is also a 'must'. I would not give anyone access to P2P sites, video streaming such as Youtube, Netflix, Hulu etc...
