Network 2?!!

Hi my network is named Network 2 and I don't understand why since I have just one computer and also it says that I'm on a (homegroup) JOINED network.What does that mean?Thanks in advance.

Hi anyone please?

Is this a laptop on a wireless network?

No, its not its cable internet with a modem.I just started using this ISP they don't use phone lines or routers just the TV cable.

Go to - Control Panel >> Network and Internet >> Network and Sharing Center

Click "Change adapter settings" then let us know if their is more than one connection listed.
Click "See full map" then upload a screen shot of the full map for "Network 2".

I believe that means you have created (or joined in the past) a homegroup which is new and available only through Windows 7 and future Operating Systems. Anyone with Windows 7 on your network and knows the Homegroup passkey can join your Homegroup. It's a bit different than the usual networking we have used for so many years.

When I click "change advanced adapter setting" I get only one Icon named local area connection network 2 and when I click see full map I get this:
"Windows cannot create the network map.Responses from the device on the network are delayed or there is an incompatible router on the network."
Last two days I set my network "Public network" since I don't actually have passkey set I thought this way is safer.
What do you recommend?
And how do you post screen shot here?

The Public network is an UN-secure connection and is not safe. I recommend using the passkey (may require creating a passkey) that has been configured for your router. Setting a passkey within the router will block anyone trying to access your network that does not have the passkey or direct connection to the router.

I was told (by my ISP) that My modem has its own passkey and that I don't need one(!) it was strange but anyway...so how can I find out what is my modems passkey?...and how can I make my connection safer?

Thats a mis-leading statement, if your router already has a passkey then use the passkey or change it (I assume all passkeys can be changed).

Thats hard to say sense all modems are different and the setting for the passkey will be found in different locations. I know some ISP's will place the passkey they assigned (probably a random generated key) on a label and stick it to the modem. If the passkey is not on a label, there should have been paperwork with the modem that has it somewhere.

By using any encrypted connection and never using the "Public network". Public networks are used in public for anyone to use that wouldn't know a passkey. It is advised to use extreme caution when using one of these networks in public. When you create a Public network at home, you are in a sense inviting anyone to use your Internet connection and possibly access to your computer.
