I have an ethernet LAN at home with my computer acting as server and 3 others connecting to my computer for internet. Recently, I purchased a new laptop and added it to the network.
The internet worked perfectly but then I noticed that the internet connection on one computer was disconnected and on another computer it worked sporadically, i.e. connection to a website was established 2-3 mins later.
There was a correlation between the sporadic computer and the new computer. If the new computer was idle, I could access the internet perfectly on the sporadic comp but then the internet connection on the new comp became sporadic and vice-versa.
I connected all the computers using a Linksys Ethernet hub which has 6 ports. One port is for uplink-which my computer uses as it is the server. Out of the remaining 5 'client' ports, 4 are now used. If I disconnect the new comp from the hub and the network, the internet on rest of the computers works perfectly.
I get a 1.1 Mbps broadband connection from my ISP and connect using a USB modem without any inbuilt router. I have also set the netword card speed to 100 mbps full duplex on each computer.
Each computer has the same DNS and is given an IP for the network using DHCP.How should I overcome the problem so that the internet connection is not compromised on any computer? Is it because I have used 4 out of the 5 available ports or it is something else? Do I need to buy a hub with 8-9 ports? Please advise. Thanks.
