Help Understanding Wireless Routers + Net Speed

Hello All,

I am looking for someone that is knowledge in this subject. I always been experiencing wireless speed cutoff with ever router I ever bought. I have a 75mb down line but when I connect to the wireless I get like 20mb down. The up line is always normal but the down is always cut in half or sometimes even 1/3.

What is the reason that may cause behind this? I am currently using a Asus AC1750 i think.

Any information would be appreciated. If it is an setting wise, that would be great, I don't have to spend money buying a new device. Thank you in advance.
 
What wireless NIC are you using in your PC? You can have an AC router but if your NIC only supports G speeds then you will negotiate to G speeds.

Throughput also depends on congestion and signal strength. If there are a lot of neighboring APs competing for the same airspace it will degrade performance fairly quickly (mainly just a concern for the 2.4 GHz band).
 
Thank you for replying back to my post.

I am comparing it with my phone devices/tablets. My sister uses a Galaxy s4 and when she does a speedtest she gets 84mb down but when I do a speedtest on my Galaxy Note 4 I get 20mb down. I am actually unsure about the laptop and tablet's wifi adapter.

When G speed I assume it is 2.4 and N is 5.0? What is maximum speed in MB if possible can G speed go up to. Correct me if I am wrong. I never understand type of routers and higher speeds.
 
It seems like the device connecting to your router is the culprit. N can work in 5 Ghz or 2.4 Ghz.

G has a speed of 54 Mbps and N has a speed of 300 Mbps. Those are theoretical router speeds however, not you ISP's Internet speed.

On your phone, before running a speed test go to Settings > WiFi and click on your connected network, it will tell you the negotiated speed. It's possible her phone is connecting at a higher speed than yours due to many reasons.
 
I am an IT student with a very basic entry level of networking knowledge, but I would also consider the number of devices connected to the router wirelessly a possible culprit to this issue as well.

^ Device priority can also be set on some routers. Highest priority will get the most bandwidth, I believe.
