The UGREEN case was bought on Amazon : https://www.amazon.fr/gp/product/B07D2BHVBD I don't have the UGREEN packaging, but according to product number on Amazon description is should be : https://www.ugreen.com/product /type_c_to_sata_external_hard_drive_enclosure-en.html If I plug an USB key on either USB2 or USB3 there is no problem. -- 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.
