High ping, slow speed on win 10

[Dmitrii]

I am experiencing abnormally high ping (500 + ms) in games (and pretty slow download speed for 1000mb plan).

The issue is somewhere in router (tg3482g, firmware TG3482PC2_4.0p1s1_PROD_sey), I checked it by connecting to another wifi that I set up from my cell phone on verizon. Also, I've tryied to run the same game on my Mac and I didn't find ping issues. So I beleive, there is some weired settings on router specifically against windows.

But I have no Idea how to fix this, so I'm asking for help.

P.S. why wifi settings on a router are managed automatically and I can't change it? this makes me call support in order to diagnose my problem that, I am pretty sure, I can handle by myself.

I have no option to test wired connection, but I know that I am able to play if I use my iphone personal hotspot (verizon) and I am able to play via same network (xfinity) from my mac.

Maybe I should replace the router? I think if this will not be resolved I'll have to use that "early termination" thing.

Just replaced XB6 with Netgear AC1900 (C7100V) - Still spikes, wifi performance became little bit worse.
