Solved: 3G internet very slow over the network

Hi,
I have set up a network of 7 systems which are connected to each other using a switch and CAT 6 cables. All the systems are loaded with Windows XP service pack3. I have also purchased the 3G internet connection which uses a USB dongle. I have shared this connection using a proxy server which is called as analog x. The speed of the connection on the system to which the dongle is physically connected is excellent and very fast. The other systems on the network can access the internet and browse through websites. But the speed is terribly slow and half the pages will not open at all. Gmail will never load. The home page of most of the websites loads up correctly but then the subsequent pages will never load and just time out. This had become a major problem since it is a cyber cafe.
Could this be any problem with the cabling? Should not be actually since the games are working perfectly fine without any problems. But I must tell you that the batteries for the backup are placed very close to the cables. It is a stack of 8 batteries. Could this be any problem? Again it should not be since I tried connecting two systems using a cross cable ( one system with the dongle and the proxy server and the other one as the client) Again the same problem.

I need to get this sorted as soon as possible as I am losing endless number of customers.
Please help me out guys

Thanks a lot, Merry Christmas!!

 

Well I haven't tried ICS. Will give it a shot. I use this program so that I can give manual IPs to the systems. But let me give it a shot. Will keep you posted. Thanks TerryNet

 

Or get a 3G router capable router.

 

Thanks TerryNet and sorry for the late reply. ICS did the job well. It is working fine now. Happy New Year
