Which classes of IP are not used or are totally banned?

Why am I losing connection with my WiFi? We have a WiFi installed in our house. After some configuration work my laptop was connected to it wirelessly and would automatically detect it every time I open my laptop. One day, after some months, I suddenly lost connection with my home’s WiFi and when I checked available connections my laptop showed another WiFi signal that I later learned belonged to my neighbor.

After several trial and error attempts, I discovered that I can only reconnect to my own WiFi if I shut down and reboot my computer. This thing happens every time my neighbor’s WiFi becomes available after mine. What must I do so I wouldn’t lose connection at the middle of my work? Thank you for your generous attention.

Hi,

I am running a wireless-N network with DLINK DIR-615. I have Windows 64-bit with Atheros wireless card.  Everything seems to work perfectly but at a certain time 2-3x in a day my wireless connection goes lousy.

When I ping my router, at average I lose 25%. I had already updated my wireless drivers and it seems to be the same.

Hey,

If I have a company and I'm implementing dial-up services to enable remote office employees to connect to the local network. The company uses several Layer 3 protocols on the network. Authentication of the users connecting to the network is required for security. Additionally, some employees will be dialing long distance and will need call back support.

I want to know about the newly launched networking site Google plus. How does it work ? How to get connected to this networking site.  Do I need any invitations from others to join this site ? Any help ?

What is the meaning of IP address. Naturally we see an IP address consists of several numbers. What is the significance of those numbers ? Who provides IP addresses? Is there any one who can answer all these questions?

Hey guys,

I am running a SQL Server and Windows 2003 server computers both on the same server computer.

I was trying to log in using windows authentication and the OS loads fine then I get this error message:

Cannot connect to MS SQL.

Additional information:

Cannot generate SSIP context. (Microsoft SQL Server)

OK

Any help guys?

Thanks.

I had my router for few years now and I know that there are newer models out there better than mine. I don't actually have problems with my current router but is there a way to get it updated?
