Access Control; allow others on your wireless network
There a couple of ways to protect your wireless network from uninvited visitors. The most used one is probably the WEP protection; you make a key…. if someone want to get onto your network – you give him or her the key = and they have access to your network.
What happens if you do not want that one on your network anymore…??
You change the key – and everybody who wants to enter your network will need to change into that new key.
What if someone (by accident…??) gives that key to someone else…?? You probably will never notice that uh…??
The protection I use…??
I use the Access Control option; wireless routers/modems will have this option - you will enter the MAC-addresses of computers you allow on your network…. As a MAC address is an unique identity of the network card; someone else is not able to get onto that network… !!!
Combination of Access Control and WEP would even be the best security…. !!
In case you do not want someone any longer on your wireless internet; you just remove that person his MAC address from your router !!!
To find the MAC address; go to your Network Connection – double click the connected wireless card – the Support Tab – Details – Physical Address is your MAC address !!
Does my mac adresse change if I upgrade my computer with some other hardware? For example change the graphic card?
The only hardware which will make your mac address change; are network cards AND the wifi usb sticks….
Graphic card is not going to change it….
