Is my network card the problem?

[surge101]

So I bought an ASUS ROG GL551JN-DH71 about 2-3 months ago. Over the past few weeks i've been noticing that if i'm not in the same room as my router, the internet has been very slow and completely unreliable in maintaining a connection to anything. For a while i've been blaming my ISP and my router. However, today, I decided to turn on my old laptop, which I am posting on right at this moment and the connection is fine all throughout the house. I'm a little confused as to what the issue is exactly, because the wifi connection on my computer with the issues still shows 4-5 bars of connection on the task bar, also, if I reset the router, it usually works fine for a few minutes, which is why I initially thought it was an issue with the router/ISP. However, as I said, my old laptop works fine, my phone works fine, all on the same wifi connection. Not sure what to do at this point.

Does the ASUS have any network 'enhancement' or boosting software? Often these are the culprits in otherwise good systems.
