Hi, I'm having an issue where my wi-fi will drop for about 2-10 seconds. Each time it does this I am dropped from my sc2 game. This happens occasionally when I am in normal laptop usage but much more often when I run Starcraft (every 10-20 minutes).
I'm on a 100mb/s plan and typically get around 35mb/s on wi-fi. I live in an apartment with a lot of wi-fi signals available (~30) however only 5-6 devices connect to my router. Router sits in next room through 1 standard wall and I have full bars reception.
Laptop specs: Brand new ASUS S410U i5-8250 16GB RAM with 256GB SSD wi-fi adapter is qualcomm atheros QCA9377-3 802.11a/b/g/n/ac
Router specs: NetComm Wireless NF4V
Router settings: https://gyazo.com/19a2d9913c39b9fac02d3f1b77df36bc 2.4Ghz and 802.11n
What I have done: 1. Updated wi-fi drivers 2. used wi-analyser and changed my router channel to least crowded channel. (channel 3 - default chanels 1,6 and 11 are all very crowded). 3. Performed factory reset of router. 4. Changed router bandwidth to 20Mhz and back again
Have been trying to see if my phone drops at same time as laptop but very hard to test as it's only a few seconds anyway. Unfortunately my laptop doesm't have an Ethernet port so really want to resolve this problem. Could SC2 be the problem? Any help appreciated.

I'd probably blame this on your router, if it only supports 2.4 GHz then it's very old. Upgrading to a model with 5 GHz 802.11ac support will provide a much more reliable connection. 2.4 GHz is full of interference from not only Wifi, but pretty much all kinds of wireless technology - bluetooth, cordless phones, wireless headsets, microwave ovens, etc. 5 GHz is much cleaner since the signal doesn't penetrate as far.

I'm sure that wouldn't hurt. It's strange though, I played an hour vs AI no problem then first game vs a person I have the disconnect problem, it disconnected me from battlenet. It feels like it happens way more in SC2 than normal web browsing as well so is it some kind of trouble sending/receiving data to blizz server somewhere?? Often seems to happen during first battle when there are a lot of units on screen too..

Your issues would be far more noticeable in a game than a web browser
for a quick test you can open command prompt and run a repeated ping to a good server, e.g. "ping 1.1.1.1 -t" - exact spaces, no quotes. It'll ping every second. If you have a solid and stable connection then you'll have a similar ping each time, if it's unstable then the ping time will increase or you'll drop packets. You can do it with several servers/websites to make sure that the problem is on your end somewhere.
2/3'rds of the bandwidth not reaching you (if you're actually getting anywhere near 100mbit into the router) implies major connection issues
If you connect via cable and the issues disappear then it's obviously due to wireless connection issues as well

The chances are high that someone is 'appreciating' your wi-fi. You need to whitelist your devices and blacklist everything else by default.
From what you described, it could also be a CPU problem. Make sure that you don't have a virtual network modem booster running. If you do, then your wi-fi will slow whenever your CPU tops 99% usage.

edit - I'm retarded, didn't see you already did this.

Plug your laptop directly to the router by ethernet cord. If the problem persists then you know its your wireless connection. This happened to me as well, then I got a powerline adapter and I never had drops again.
