Thanks for the quick replies.
I have access to only Router B, that's why I am connecting my computers through Router B. I cannot connect my desktop nor my laptop to Router A directly because I only have one line coming from Router A, I could connect either desktop or laptop to Router A directly.
I cannot connect to the internet on the laptop if I enable DHCP and IP Setting automatic on desktop and laptop. But I am able to get through on the laptop if it is disabled. The problem is that I get disconnected a few minutes afterwards. I can reconnect the laptop by pulling out the laptop connection and sticking it back in, but in order for me to use internet, I would have to do this again and again every few minutes.
If I connect the connection from Router A into Router B's Internet port, instead of one of the 4 other ports, neither the desktop or the laptop could get online.
If I swap the desktop and laptop connection slots on Router B, the laptop connection still disconnects after a few minutes. And I could reconnect if I pull out the laptop connection and stick it back in.
If I change the cat5 wire used for connecting the laptop, same result.
I am puzzled because I was able to get this exact setup to work for hours previously. I did not change anything on Router B, my desktop or my laptop.
What are the range of things it could be? I think I've tried what you guys have mentioned. Are there additional ways of troubleshooting this? Thank you for your inputs.
