Wifi issue guidance

[capttony]

Self hosted on a server (VPS). The issue I am having is when I try to use Snapdrop at work on a public WIFI I can't transfer anything. I can see myself on other devices but no transfer. This works flawlessly at home on my own WIFI. I installed my own router and hooked it up to the guest wifi and that aloud me to see and transfer files. This worked great for several months. My work did some upgrades on the wifi and now it is spotty. By spotty I mean, I have to turn on and off the the wifi, switch between 2g and 5g, and refresh page several times to get noticed. again this works fine at home so I am confidant that it is a wifi issue. I use Portainer and I checked the logs there and did not see anything. Any Guidance would be appreciated. Thanks
