Is there a problem with my network card?

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.

 

Are your drivers on the new notebook up to date?

 

There appear to be more reports concerning this model. Perhaps they've only used a single antenna (to save costs), or routed the wires incorrectly; all panel manufacturers warn of this. But yes, check drivers first.

Spoiler: display lid and wifi antennas

 

What Wi-Fi card is it?

 

So I downloaded the intel driver utility to update the drivers and I noticed a very slight improvement, still goes very slow and drops connection, sometimes even when close to the router.

In my device manager it is a Intel Dual Band Wireless-N 7260

 

Are you using the 5ghz band or the 2.4ghz band?

I'm using WHQL Intel driver version 18.0.0.11 with an AC-7260 that should work fine for your N-7260

You can also try WHQL version 17.16.0.4

If you have a U-APSD support setting in the WiFi card's advanced properties make sure it's diabled

 

I'm not sure how to check which one I am using, they are both set to to auto values under the advanced tab.

 

Your router setup should have different names for the 2.4ghz SSID and 5ghz SSID if it's a dual band router
Which router do you have
Select channel 7 for 2.4ghz and 153 for 5ghz and see how that works.
Select WPA2 AES(PSK) as your wireless encreption.

click on the white bar icon in the taskbar near the clock to select the 2.4ghz SSID name or 5ghz SSID name

 

I'm not sure if it is dual band router. My old router was and broadcasted both 2.4 and 5ghz, however the one im currently using is a combo router/modem from the ISP.

 

Still it does have a sticker with a model number somewhere, doesn't it?
