Fortnite (and other games) keeps freezing, using Advanced Gateway with pods

[ucla1995]

I've rebooted dozens and dozens of times. Just cannot play Fortnite or any other game anymore. Web browsing works fine. Using Advanced Gateway and have 3 pods. Speedtest shows solid speeds in the 100s. Port forwarding doesn't help either.
Should I try to swap out the Advanced Gateway box? Or are Advanced Gateways just bad for gaming over WiFi?  I cannot go to a wired connection, not practical in my house.

thank you in advance

I should add I've tried pulling all the pods and sitting next to the gateway and it still happens.

Perhaps MoCA adapters may be an option for you. Google "MoCA adapters" for more info.

Unfortunately a Moca adapter solution won't work since I mostly game off an iPad (i.e. no way to wire that connection even to a coax outlet).
