It's still happening, Raspberry Pi 4 ( Raspberry Pi RAS-4-4G - Model B / 4 GB SDRAM (1822096)) and Ubuntu Core Servier 23.10
When I connect SSD drive to USB3 port (booted from SDCard), internal WiFi doesn't work, and most of the time I can see error: brcmfmac: brcmf_set_channel: set chanspec 0xd0.. fail, reason -52 (random data in place of 2 dots) I don't think it's a power problem, I use official 3A power supply, Also, I can use my additional USB Wifi adapter connected to other USB3 port - it works, when internal not. -- 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: Confirmed Status in linux-raspi2 source package in Eoan: Confirmed 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.
