We have a LAN connect to Internet through ADSL Modem of ISP. The problem is when we use 8 ports of DLINK Switch within the LAN and connect to Internet, then the access speed is OK. But when we use 16 ports of 3COM or DLINK then connection speed drop from 512kbps to 30kbps, unbelievable. We have replace the new switches with the same 16 ports, but the problem still happen the same thing.<br />
<br />
Why we are facing with slow connection when we use 16 ports of network switch? While 8 ports is OK, nothing wrong.<br />
<br />
Remark: The LAN connection is OK, it only happen on Internet connection; the speed is very slow when we browsing the web.<br />
<br />
Please advise.<br />
<br />
<br />
Thanks,<br />

Networking hardware includes the physical devices facilitating the use of a computer network. Typically, networking hardware includes gateways, routers, network bridges, modems, wireless access points, networking cables, line drivers, switches, hubs, and repeaters. But it also includes hybrid network devices such as multilayer switches, protocol converters, bridge routers, proxy servers, firewalls, network address translators, multiplexers, network interface controllers, wireless network interface controllers, ISDN terminal adapters and other related hardware.

The term broadband commonly refers to high-speed Internet access that is always on and faster than the traditional dial-up access. Broadband includes several high-speed transmission technologies such as digital subscriber line (DSL), cable, fiber optics, wireless (for which there is a separate topic), satellite and broadband over powerlines (BPL).

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.
