Laptop connection problem

[DevilSniper666]

Hi Guys!

I recently got a new laptop (Acer aspire 5750) and I am having trouble connecting to my home network. I can connect when I am upstairs, not far away from the router but when I move away to the end of the house it will have trouble connecting to the internet. It shows 2 or 3 bars with a yellow exclamation mark. When I click on the symbol it say 'Limited Access'. I have tried the Troubleshoot but it cant find any problems.

I know that I am in range (not that stupid ) because my brother's laptop will connect from far away. Also because it will show my network in Network selection box with 3 bars next to it.

Do you know what I can do to solve this strange problem?

Thanks in advance!
