Question Issue with desktop gaming forcing wifi to turn off

[Solidjake]

Good morning guys. This problem has been persistent the past two months with my ARRIS SBG6580-2 wireless modem. (internet provider is Spectrum). If I do a speed test on the desktop (ethernet cable) the speed is around 300 mbps as it should be. When I check the speeds via my Pixel 2 XL/macbook on 2.4ghz speed goes down to 35mpbs and at 5ghz its higher but around 70mbps.

Now, when I launch games (such as Project Cars 2 even with career mode) the wifi drops and I can't connect to it via my laptop, phone and google home mini but once I shut down the game it restores connection. Wifi ONLY stays connected is with the wireless on 5ghz. I do not have options to have 2.4/5 on at the same time and I need 2.4 for the wifi boiler downstairs.

Modem settings for windows 10 (1903) is set to max performance and power saving setting has been turned off with the same results. I do not see anything in the settings for the modem itself that would create this problem.

With Spectrum they only allow certain modems/routers so I won't have to pay extra per month. The one that I saw that might be better is the Netgear N750 WNDR7300 unless you see one that's better. I have the 300mbps plan but I assume up to 400 should work as well.

Any help would be appreciated.

Out of curiosity, does the wireless router you're working with have any firmware updates? Perhaps your system is bogging down the speed because it's drawing data for an update...? Which BIOS version are you for your motherboard?

It say it's the latest and confirmed the same on the ARRIS site. That might be possible but during those times Steam does not have any updates for any games including the ones that I'm playing. Later on today I can check with Origin/BFV. Bios is the latest F8 from what I recall.
