Can anyone please tell me why Firewalls are important? I use router with WPA security and I think that this much security is enough for my computers and laptops, which get connected to the internet from these routers. Guys please comment, because I am thinking of installing a Firewall.

I have a serious problem. I am using Windows 98 and I want to know whether my port is open or closed, because I want to see my control panel with the use of a website, having online services and for that I need ports 8087 and 8088 open. I have one more computer, which runs MAC but there I can access the control panel and both the computers are connected with a wireless router.

Hello friends,

I am using a shared internet wireless, in my small office but I am facing signal coverage problems.

It does not cover all the area in the office, so what do I do now?

Please Explain all type of networks.

I am a new student in this field and would thank any one who can explain them to me.

Please explain the different types of wireless networks and how they work?

When I am using my VPN at home, I am unable to get a steady connection.

When at work, I use the same laptop to connect to the same VPN.

It works fine when I am at work, but gets disconnected every 3 to 5 minutes when I am home.

Somebody please help me.

Nowadays, wireless LAN is widely used, as it is very convenient for building a network easily, without managing physical cables.

So please, I want information as to what unauthorized actions might be committed easily, in a wireless LAN environment.

Thanks.
