My wifi keeps randomly disconnecting and reconnecting

"By disappears, I meant the name of the network yea. But It eventually comes back after like 3-20 seconds by itself. I only included that to clarify that it wasn't just me disconnected, like the actual wifi is gone and I have to wait for it to come back instead of it just making me disconnect for some reason. I've restarted my phone but I'll try these things again thank you"

Reset your Network Settings:

Make a record of all of your connections' credentials, and then reset your network settings. If you don't keep a record, then it'd be lost. So, to play it safe, backup your iPhone(to a computer) and then perform the reset. If a network reset doesn't not work, then restore from the backup you created.

"My wifi keeps randomly disconnecting and reconnecting: [...]When it disconnects, it doesn't just disconnect and I go to wifi tab in settings and rejoin, it disappears from the wifi tab for a few seconds, usually anywhere from 3-15 seconds, and I'm really confused why.[...]"

Troubleshooting WiFi Connections:

What "disappears"? If you are referring to the SSID (the name of the network) vanishing off of the list of networks, then restart your router. over it off for 30 seconds and then power it back on.

Perform a Force Restart:

Try Force Restarting your iPhone. Save any information that need be prior to doing to. Then try the connection, once more.
