Router的安全問題

if u are not using the wi-fi router, it is sure that there is no 無線網絡. =.=
if u are using the wi-fi router..
there is a page that usually called ''wireless settings'' in your setting pages,
which is going to setup the wi-fi channel, and protection.
there are several choices, u can choose a type of encrytion.
if u dont understand, u can tell me that what model of your router is, i will show u the detail step.

actually, although u set the protection, somebody who knows the cracking method of
wi-fi protection still can crack your password. but i think if u did set, then it lets somebody who doesnt know computers cant use your network.

最好既方法係一定係set密碼
