Unstable WiFi: Who's fault? Router or USB WiFi Adapter?

[Eirwn]

Hello Community,

I have 2 computers at home.

1 - With Ethernet cable: Super Stable internet connection, no problems in general.

2 - With USB WiFi adapter Netgear WNA 3100.

The 2nd computer have some stability issues that appear as high Ping while playing League of Legends. While doing a speed test i can see these kind of "bumps" on the graph provided by the OOKLA speed test and I believe that they are pretty much normal, cause my Netgear USB adapter is quite old and wasn't very expensive etc etc.

THE ACTUAL PROBLEM

I am thinking of connecting Computer #1 with WiFi as well, because the Ethernet cable is running through the living room. I am not planning to be cheap about it and I am thinking buying this ASUS PCE-AC68 Wifi adapter.

Although I am afraid that there is a chance that my ZTE ZXHN H108N Modem-Router (given by the internet provider - Vodafone Greece) is the actual problem, and it doesn't provide a good enough WiFi signal, therefore my 90 Euro ASUS PCI adapter is going to be as bad as my old one.


THE QUESTION

How can I test how good is the WiFi signal provided by the Modem Router before I go and buy a new and expensive PCI WiFi adapter?

Usually the modem/router combos do not have very good hardware. But you also did not list how far away you are from the router or how the area is setup. Best thing for quality is to have the ISP configure their hardware to be a Modem only, and then get your own Router where you can pick what you want. http://www.tomsguide.com/us/best-wifi-routers,review-2498.html

Well, the router at the moment is at the same room with the Computer, but when i get my home office set up, It won't be.
