Recently I expanded LAN in my office from 3 to 10 computers.
Structure star topology, one ADSL Modem connected to One Switch which is again connected to 10 computers.
Also we have Wifi device Netgear which is connected from switch.
ADSL Modem acts as the DHCP Server, all the system will have default gateway IP (ADSL Modem's IP)
Network latency is now become very high, All the chat severs disconnect often like google talk, skype etc, also internet become very very slow. when all the computer turned on.
We have 4 Mbps Download and 100 Kbps upload Net speed.
Its look like ADSL Modem cannot able to handle all the connections. I tried to setup a system as default gateway which will connect to modem, not sure how to do this.
Please advice on this.
