I confirmed that the issue happened again when an additional laptop was started up (connected to wifi), as my work computer (with cisco anyconnect) fully lost connection and had to reestablishthe secure connection, but not until 2-3 minutes later when it reconnected to the network. I've looked in the router settings and have not found any way to change QoS, is this something that can be modified at all? Or does Cox not allow for changing these settings within their products? Thanks for your replies, I very much appreciate it. Re: Why does my wifi disconnect whenever my roommate's phone or computer connects? The modem is a Cox Panoramic Gateway. The PC is hardwired, but even if it weren't, a single device connecting to the network shouldn't cause all other devices to drop their connection. Not for the amount I'm paying for Gigablast internet with "the best available modem." Re: Why does my wifi disconnect whenever my roommate's phone or computer connects?

Every time he gets home, or starts up his pc, my phone/ps4 briefly loses internet connection via wifi.
