A wired network is more reliable and has generally a higher bandwidth (is faster..) than a wireless network; while it constraints to the availability and length of connection cables, can be more expensive than a wireless network and may not fit specific situations such as reaching some remote areas or being used with mobile devices.
Advantages and disadvantages of wireless network
Advantages:
* Flexible if there is ad-hoc situation when additional workstation was required. * Implementation cost is cheaper than wired network. * Ideal for the non-reachable places such as across river or mountain or rural area. * Ideal for temporary network setups.
Disadvantages: * Lower speed compared to wired network. (of course!) * Less secure because hacker's laptop can act as Access Point. If you connected to their laptop, they'll read all your information (username, password.. bla..bla..bla..). * More complex to configure than wired network. * Affected by surrounding. E.g: walls (blocking), microwave oven (interference), far distance (attenuation)
| Wired/Cabled | Wireless | Installation | Wired connections are easier to set up. With most modern computers you can simply plug in the cable and get on the Net. | Wireless requires configuring the router and at least one extra step on the computer’s side: searching for the correct network to connect to. | Cost | Hardware components such as Ethernet cables and switches are relatively inexpensive, and the software required for connection sharing may be obtained for free | Wireless equipment such as routers and wireless cards are comparatively more expensive. | Reliability | Ethernet cables, hubs and switches are extremely reliable, mainly because manufacturers have been continually improving Ethernet technology over several decades. | And like cordless phones, problems increase as you get farther away from the router.
