The 2.4GHz is getting more crowded but more widely used due to the fact that many devices are also using 2.4GHz band(mobile device, tablets?) and because of this, you will get the signal interference with the wireless connection when you use the 2.4GHz band. By changing the band or channel of the wireless connection, you can decrease the signal interference.

The wireless and Bluetooth combo card share the same bandwidth and the antenna, and when the Bluetooth function is turned on, the total throughput will be shared by wireless and the Bluetooth connection. Theoretically the throughput for 802.11n, 2.4 GHz band with 20 MHz channel is 72.2 Mbps on Intel AC 3160, but the actual throughput will be lower due to the environmental signal interference and the Bluetooth's shared throughput. For the AC WLAN adapter, you can get the maximum performance by connecting with a compatible AC router and 5GHz band connection. If you have the 802.11n and 2.4GHz band for your connection, the throughput of the wireless connection on AC 3160 will be lower due to the reasons mentioned above, and you may be getting a unstable connection. To improve the stability of the connection, we suggest 1. Find the optimize wireless connection by adjusting the settings for the router and the WLAN adapter. 2. Turn off the Bluetooth function if you don't have any paired devices and avoid the shared throughput.

For more detail settings of the WLAN adapter, please read through the FAQ file from the blow link.

Why don't you just stop lying?

I have been using my 2.4Ghz Wi-Fi connection whithout any problem with all my previous laptops and computers.
The Wi-Fi is OK on my GS 60 2PC Ghost only when the GPU is OFF.

I tried everything I found on the internet but nothing worked.

The problem has nothing to do with interference or user settings.
The GS series is defective by design, stop blaming the customers.

I can't afford to RMA my laptop right now as I use it to work.

have you 2 tried doing wifi driver update? i just did that myself and right now i'm testing to see if my problem remains since my 5GHz band keept droping out lately at download speed 8-10MB/s then it dropped out and 5GHz band wifi disapeared on list so i had to disable wifi and re-enable it to make it appear again and then shortly it would drop out again so i will return and see if issue remains now after i did driver updates.

durring test i googled this isuse around and one site gave me this

Intel support then asked me to disable U-APSD (only available in the 17.0 version of the driver).  This seems to be working.

You can disable this setting by doing the following:

Load Device Manager
Right click the Wi-Fi adapter ?> Properties
Click on the Advanced tab
Set U-APSD to disable.

have you then tried disable the bandwidth management on killer network manager? since wifi will allways give you higer ms what so ever depending what router you use :) if you got wireless N router you wont get much mbps speed if it's old N versio nthen you may only recive 30mbps max and that could give you an 600-800ms if hosted/server is located on other side of world.

The theoretical throughput for 802.11n, 2.4 GHz band with 20 MHz channel is 72.2 Mbps on Intel AC 3160 while by using 802.11n, the same band and channel, you may get a higher throughput on some 802.11n WLAN adapter(depends on different spec of the adapter). For the Intel ac 3160/7260 WLAN adapter, they have their best performance by using 802.11ac, 5GHz band with 20 MHz channel.

just a note msiTechNB the issues people are having has nothing related to speed or w.e they use 2.4GHz or 5GHz the issue is whenever they play they get good ping and fps but shortly both ping and fps drops down to very low well ping becoms higher while fps drops then it returns to it's original state again no lagg nothing and shortly it happens again so what your stating has nothing to solve this problem.

I spoken to al3xandruc about issue and what he is telling me is that when he goes into bios and changes primary display from SG to IGFX the spike on fps and ping never ocoures but once he put IGFX back to SG and play like CS:GO then issues occoures again.

So either nvidia gpu is eating more Voltage so wificard retrives less to handle signal state so ping raises to 1200-2000ms then drops down to around 60-120ms again and then back to around 1200-2000ms and so on but it never happens when nvidia gpu is disabled then ms remains stable.

Update: Just tested some CS:GO wireless on 5GHz band on my GS70 - 2PE and issues that everyone get doesent happen to me i didnt get any lagg at all so yeah i wonder why everyone else is getting it :/

Hi,

I've sent my cousin's GS60 2PE to the service center couple weeks ago because he has the ping spikes problem when playing DOTA2. After we got the unit back, the situation gets improved. According to the service center, they've added some shielding materials to the unit to improve the situation. You should contact with the local service center and ask them if your unit needs to add those shielding materials.

Good luck!

Not all laptops have 2 antennas.... Some have 1 some have 2, and in some of your more powerful builds, 3.  It all depends on the card, and if its both Wi-Fi and Bluetooth...
