By coexistence of wireless LAN and wired LAN, all are happy!
By using together, wireless LAN and wired LAN are more convenient, and they can do network environment effectively.
We introduce method of combination of wireless LAN and wired LAN connection and the safety this time.
At first, there are merit and demerit in wireless LAN and wired LAN each.
By knowing these characteristics, can use wireless LAN and wired LAN properly by place and Uses well.
Merit demerit of wireless LAN and wired LAN
There are following merit and demerit each when we compare wired LAN with wireless LAN.
Merit of wireless LAN
- It is not necessary to be connected with LAN cable.
Demerit of wireless LAN
- There is the risk of electric wave interference with other apparatuses.
- There is blind spot where electric wave does not reach in house.
- Transmission rate with apparatus which electric wave has weak becomes slow.
Merit of wired LAN
- Connection is stable.
- If other conditions are the same, transmission rate is faster than wireless LAN.
- It is hard to receive electric wave interference.
Demerit of wired LAN
- Cable is obstructive.
- Disconnection is possible.
It connects thing which wants to keep transmission rate to wired LAN, and it is recommended to tie thing which we want to use freely without minding speed to Network with wireless LAN.
For example, it will be convenient when we use desktop PC and notebook-sized personal computer when notebook-sized personal computer which often carries desktop PC in wired LAN connects in Wireless.
About wired LAN function of router
General wireless LAN router has wired LAN built-in.
Specifically, port ofWAN (Wide Area Network) and LAN is prepared for by the body and becomes able to connect there LAN cable.
If it is wireless LAN router of deferment type, WAN port X 1, LAN port around *4 are standard.
We connect WAN port to the Internet line with LAN cable and LAN port connects LAN cable each and can connect to PC and printer, digital AV household appliances.
Of course we can use together with wireless LAN apparatus, and LAN communication between apparatuses is comfortable, too.
As for the apparatus which does not usually move including desktop PC and digital AV household appliances, smartphone and tablet, apparatus to carry including game console should use wireless LAN using wired LAN.
In addition, there is apparatus which can get near transmission rate and stability from wired LAN if even wireless LAN is close in distance between apparatus recently.
For example, printers make Wireless type and can reduce cable wiring in house by installing close to router or repeater.
About safety of combination connection
When it connects wireless LAN and wired LAN to combination, it is the safety that begins worrying.
It is necessary for security side to be careful in particular with we wirelessly connect.
If security is weak, anyone becomes able to access wireless LAN unlike wired LAN.
Naturally we can access terminal connecting wired LAN with when we can access wireless LAN.
To keep safety
When you set wireless LAN to keep safety of wireless LAN, you must perform setting of security at the same time.
However, it is necessary to obtain commercial wireless connection utility when driver of wirelessly connecting does not enter the PC body.
It leads to using Network efficiently to enhance security of wireless LAN. When we make access point setting, let's perform setting of security at the same time by all means.
Router - very with high security capability recommends that we use router - which we can set which, at first, easily raises security recently as multi-model appears.
