Constant ping spikes during gaming, faulty wifi excluded

Experiencing constant lag spikes, run a lot of diagnostics but to no avail. Anyone have an idea?

My PC would run at around 40 ping when playing online games, but I've recently had some lag spikes up to 300 ping every 10 seconds or so. I could live with it but I tried fixing it, which for some reason made it worse. I logged onto my router to try different channel settings but ultimately ended up just restoring to default, since it is programmed to automatically change to an uncrowded channel. Now I have constant ping from 100-400. I've excluded the possibility of the internet itself having a problem, since other computers on my network don't have any issues. So it's got to be my laptop. It's a HP ProBook with a Qualcomm Atheros QCA9565 802.11b/g/n WiFi Adapter. If I turn it on and off, I have a moment of clarity with 40 ping for a few seconds before sinus curve ping resumes. How do I fix or diagnose my wifi adapter?

Router and modem in one: Sagemcom-FAST3686V2
Laptop model: HP ProBook 430 G1
OS: Windows 8.1 Pro
Wifi Adapter: Qualcomm Atheros QCA9565 802.11b/g/n
Don't think any other information is relevant to the problem, but if you need it I can provide.

Depends how hard it is to get to the wireless card. They are all pretty much a standard size. If it is fairly easy and your girlfriend laptop really is the same you could test with her card to see if the problem goes away.

The only way to say for sure it is not the wireless is to run on ethernet and have the same problems.

You only THINK the router is selecting a uncrowded channel. The router makes a selection based on the number of SSID broadcast messages it sees on a channel. I can configure a router to send 100 different SSID on a channel if I want. These are tiny amounts of data compared to the actual data transfer which you can not see with a normal router. Someone using the bandwidth is much more important than a bunch of idle routers.

In addition the newer wifi standard use multiple blocks of channels. For example 802.11ac uses blocks of 4 channels even though the SSID is only broadcast on one them. So you really can't tell which are really being used.

WiFi has almost no options you can set. You can set the channels you use and stuff like channel width...ie 20,40,80. Everything else is related to security and has little impact on performance.

You are then left with stuff like faulty device drivers and all you can do is try to find newer ones either from the laptop manufacture or from the wifi chipset manufacture.

After that there is not much you can do. Games are extremely sensitive to wifi interference. The requirements games have and the way wifi works to reduce data loss are opposite. It is the worst possible combination.

Now this may not be a wifi problem at all. Games like to lie when they say there are network problems. They overload some part of the machine (normally video) or some other part of their code. They are so busy doing that they get delay looking for the network traffic. They then say their is network delay when it was really the game that was too busy to notice that he network traffic was waiting in the buffer for it.

Plugging into the ethernet gives me a really stable connection, 39 ping without any interference. I've tried looking for updates to my wireless adapter but the last version published was in 2014, which is when I bought my computer and ultimately, with the last adapter version. My girlfriend has the exact same laptop (same driver etc) and she has no problems with ping spikes. Would the best option be to purchase a new wireless adapter that fits in, if that's even possible?
