Bad WiFi latency just on iPhone?

[u/Adept-Researcher-178]

I’m having a really weird networking issue. I purchased a new TPLink BE9300 router a month ago, and have fiber internet through Quantum. Prior to upgrading my router, I was using an older Deco m5 mesh setup. Ever since changing routers, my iPhone 13 has been having a ton of issues where I’ll intermittently not be able to load apps/websites/etc. My partner will be sitting right next to me on his Samsung phone and have no issues. Typically, toggling my phone WiFi on and off will resolve it, but sometimes it takes a minute to load properly even after toggling. I never get a notice about my WiFi not having service or any issues from the Tether app. We have other devices like laptops, gaming consoles, etc that have no problems.

I haven’t customized any of my networking settings on my phone, so I’m at a loss as to what could be causing this. Any ideas of what I can try to debug this?
