Network Speed Drops with Phone Connected
To try to make the explanation simple, if my phone (Pixel 10 Pro XL) is connected to my WiFi network, the speed drops by about 7-10x across all devices, this only happened maybe last couple weeks after having the phone on the network prior with no major changes for about 4 months.
Spectrum Gig, all Spectrum hardware. My first tests in fact were with speedtest, but at the time of initial troubleshooting it was drastic/repeatable enough for comparison at least (I did try iperf tonight, more below). Therefore I do not care about actual speeds, just the comparison with the phone being connected. But just to show how repeatable it is, I can turn WiFi off on the phone mid speedtest on the laptop, and the speed instantly jumps up.
Ethernet to router when I first was troubleshooting was ~600Mbps on a laptop. At that time of testing with phone disconnected, same laptop was ~350Mbps on WiFi. WITH phone connected, dropped to ~50Mbps.
I have no idea if I did this correct, but did try iperf between my PC (tp-link PCIe adapter) and same laptop as before. Phone connected was 11Mbps, phone disconnected was 48Mbps. Again no idea how relevant those numbers are or if I ran it correctly (set laptop as server, on PC connected to laptop IP).
It took some troubleshooting to figure out it was my phone (just noticed low overall speed at first). I tried simple things like restarting modem and router, restarting phone, forgetting network and re-connecting. I tried disconnecting other devices to see if it was some kind of device limit, no change.
There are no large updates happening or syncing through the phone, especially the behavior happening this long. I even tried changing my Spotify off of lossless quality just as a random thought. I suppose next logical troubleshooting would be to reset the phone, but I'd like to avoid that (it's only a little over 4 months old)
I would guess it'd be something phone related, so I started searching there without much luck. I figured posting on a network sub might be my best bet. Let me know if I need to clarify anything or need more info. TIA!
