I have two laptops and one wireless connection but there is a problem?

i have an old laptop which I still use and I recently purchased a new laptop. both are connected to the same wireless network. But I am having a problem with the new laptop. When I am using my old laptop, the internet access bar at the bottom corner of the task bar shows full..All bars are filled and the signal strength is high. But when I switch off this laptop and open the new laptop, I have noticed that the signal strength is low and only two bars are full showing a weak network or limited connection. I can browse the internet on both laptops. Even when both laptops are on, the signal strength on the previous or old laptop is very high whereas on the new one it shows very low. My internet connection has high connectivity. I am not able to understand why this is happening . Can anyone tell me what's going wrong with my new laptop?

As your old laptop has good network controller where the new laptop doesn't have and check here the laptops specifications matter after checking you will notice the chipset used by your old and new laptops are different.

In my point of view your old laptop has the good network controller which spread the radio waves longer, which has high frequency whereas the new laptop doesn't have and there is specific difference in 802.11b/g/n, if these models differs the spread area.

One thing is check whether your new laptop got connected any other network which might be open network the signal of that network might be low so check the WiFi settings to which network you are connected to.

Might be your both laptops are not placed in the same area and if the area differ the signal strength also changes due to distance from the router and If you have smartphone place the two laptops and smart phone connect them to your router and you will come to know the exact difference
