Could you provide a link to the hardware you are using? like 4go board and ugreen usb 3.1 case?
And btw if you connect a normal usb flash drive, does this issue happen? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-raspi2 in Ubuntu. https://bugs.launchpad.net/bugs/1857760 Title: Raspberry Pi 4 loose Wifi connection when connecting external SSD Status in linux-raspi2 package in Ubuntu: New Bug description: When I connect an external SSD (Samsung 850 EVO 500 Go in a UGREEN USB 3.1 case) on my Raspberry Pi 4 (4Go) the Wifi stop working. It is easy to reproduce, either en USB3 or USB2 connectors. The SSD is mounted, only the Wifi fails. The problem does not occurs on a fresh Rasbian. The problem does not occurs if I connect the SSD case on my keyboard (a R.Pi keyboard including a USB hub). Only if I connect the SSD directly on the R.Pi. When I disconnect the SSD case, the Wifi generally gets back, but sometimes I had to set the wifi OFF then ON (through gnome gui tooling). I don't have to reboot.
