Please help me out!

 

Hmmm...

Did your desktop work with the internet before?

 

Did you have the desktop plugged directly into a cable / DSL modem? You may have been using a crossover cable for this, which may not work with the router. Check the cable for any labeling that suggests it may be a crossover, or X-over.

desktop worked fine before. And I connected them correctly for sure. I tried numerous ways connecting cable. Is it possible to Bellsouth Blocked or make me not to use Router?

 

How many Internet users can be on at once. I know with comcast its 5 but what about yours?

 

What you mean?I thought I don't have that kind of limitation.

 

Oh yeah, only a certain number of computers can be on the internet at one time. It coulkd be that but something else. Did you do the Firmware, drivers?

 

No Since I can't go online with desktop I couldn't do it.
Should I connect with my original dsl and download it? Would you give me URL?

 

Tried but that doens't help me..should I exchange Router or should I change my dsl?

 

I would think to try to swap routers. You should be able to swap the old one for a new one. My advice to get a linksys. They havent been any trouble to me, the thing bad is there set up and you just have to know what your doing.

 

I am not sure I understand this right. If you plug the desktop directly to the cable/dsl modem, it works?
Is the desktop set to use DHCP, or does it have a static IP? Perhaps you set it to use static IPs when you used it as stand-alone without the router?

 

Yes, thats a very common problem. I think it is with the router the. Did you ever try the firmware and the drivers? Or Disabling the firewall? Or disable security?

 

I have the same router and plugging an ethernet into the router works.

I don't need to install anything, all I need is a ethernet from the router to any desktop and its automatically connected...

It's either the firmware or the router has a faulty wired connection..

 

tried everything set up tcp/ip. netgear doesn't work for me going to return this.
