[Kernel-packages] [Bug 1861338] Re: RPI4 wifi unreliable when usb3 storage is attached
I just did a test, could not reproduce this issue. Maybe your usb storage consumes too much power, could you please change other usb sticks to redo the test? on the usb-serial console, my Wifi is enabled and ping a website: ubuntu@ubuntu:~$ uname -a Linux ubuntu 5.3.0-1017-raspi2 #19+otg SMP Wed Jan 29 12:45:11 CST 2020 aarch64 aarch64 aarch64 GNU/Linux ubuntu@ubuntu:~$ ifconfig lo: flags=73 mtu 65536 inet 127.0.0.1 netmask 255.0.0.0 inet6 ::1 prefixlen 128 scopeid 0x10 loop txqueuelen 1000 (Local Loopback) RX packets 10 bytes 842 (842.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 10 bytes 842 (842.0 B) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 wlan0: flags=4163 mtu 1500 inet 192.168.2.104 netmask 255.255.255.0 broadcast 192.168.2.255 inet6 fe80::dea6:32ff:fe0e:9bc5 prefixlen 64 scopeid 0x20 ether dc:a6:32:0e:9b:c5 txqueuelen 1000 (Ethernet) RX packets 58 bytes 7614 (7.6 KB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 69 bytes 7950 (7.9 KB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 ubuntu@ubuntu:~$ ping www.sohu.com PING fbx.a.sohu.com (123.126.104.68) 56(84) bytes of data. 64 bytes from 123.126.104.68 (123.126.104.68): icmp_seq=1 ttl=57 time=10.4 ms 64 bytes from 123.126.104.68 (123.126.104.68): icmp_seq=2 ttl=57 time=6.75 ms 64 bytes from 123.126.104.68 (123.126.104.68): icmp_seq=3 ttl=57 time=4.80 ms 64 bytes from 123.126.104.68 (123.126.104.68): icmp_seq=4 ttl=57 time=17.3 ms 64 bytes from 123.126.104.68 (123.126.104.68): icmp_seq=5 ttl=57 time=5.55 ms 64 bytes from 123.126.104.68 (123.126.104.68): icmp_seq=6 ttl=57 time=5.24 ms 64 bytes from 123.126.104.68 (123.126.104.68): icmp_seq=7 ttl=57 time=5.08 ms 64 bytes from 123.126.104.68 (123.126.104.68): icmp_seq=8 ttl=57 time=6.37 ms 64 bytes from 123.126.104.68 (123.126.104.68): icmp_seq=9 ttl=57 time=6.56 ms 64 bytes from 123.126.104.68 (123.126.104.68): icmp_seq=10 ttl=57 time=4.25 ms 64 bytes from 123.126.104.68 (123.126.104.68): icmp_seq=11 ttl=57 time=7.62 ms 64 bytes from 123.126.104.68 (123.126.104.68): icmp_seq=12 ttl=57 time=4.09 ms 64 bytes from 123.126.104.68 (123.126.104.68): icmp_seq=13 ttl=57 time=7.59 ms 64 bytes from 123.126.104.68 (123.126.104.68): icmp_seq=14 ttl=57 time=7.78 ms 64 bytes from 123.126.104.68 (123.126.104.68): icmp_seq=15 ttl=57 time=6.42 ms 64 bytes from 123.126.104.68 (123.126.104.68): icmp_seq=16 ttl=57 time=4.29 ms 64 bytes from 123.126.104.68 (123.126.104.68): icmp_seq=17 ttl=57 time=4.03 ms 64 bytes from 123.126.104.68 (123.126.104.68): icmp_seq=18 ttl=57 time=4.06 ms 64 bytes from 123.126.104.68 (123.126.104.68): icmp_seq=19 ttl=57 time=13.3 ms 64 bytes from 123.126.104.68 (123.126.104.68): icmp_seq=20 ttl=57 time=4.16 ms 64 bytes from 123.126.104.68 (123.126.104.68): icmp_seq=21 ttl=57 time=11.1 ms 64 bytes from 123.126.104.68 (123.126.104.68): icmp_seq=22 ttl=57 time=6.45 ms 64 bytes from 123.126.104.68 (123.126.104.68): icmp_seq=23 ttl=57 time=5.60 ms 64 bytes from 123.126.104.68 (123.126.104.68): icmp_seq=24 ttl=57 time=3.86 ms 64 bytes from 123.126.104.68 (123.126.104.68): icmp_seq=25 ttl=57 time=5.81 ms 64 bytes from 123.126.104.68 (123.126.104.68): icmp_seq=26 ttl=57 time=6.88 ms On a console via ssh, we can see a usb stick is plugged into the usb3 and mount it to /mnt/ [ 142.964958] usb 1-1.2: new high-speed USB device number 3 using xhci_hcd [ 143.065593] usb 1-1.2: New USB device found, idVendor=0781, idProduct=5575, bcdDevice= 1.27 [ 143.065609] usb 1-1.2: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [ 143.065620] usb 1-1.2: Product: Cruzer Glide [ 143.065631] usb 1-1.2: Manufacturer: SanDisk [ 143.065640] usb 1-1.2: SerialNumber: 20043109300EAD30F6EF [ 143.117186] usb-storage 1-1.2:1.0: USB Mass Storage device detected [ 143.119025] scsi host0: usb-storage 1-1.2:1.0 [ 143.119391] usbcore: registered new interface driver usb-storage [ 143.124401] usbcore: registered new interface driver uas [ 144.130229] scsi 0:0:0:0: Direct-Access SanDisk Cruzer Glide 1.27 PQ: 0 ANSI: 6 [ 144.131441] sd 0:0:0:0: Attached scsi generic sg0 type 0 [ 144.132701] sd 0:0:0:0: [sda] 15223808 512-byte logical blocks: (7.79 GB/7.26 GiB) [ 144.134146] sd 0:0:0:0: [sda] Write Protect is off [ 144.134161] sd 0:0:0:0: [sda] Mode Sense: 43 00 00 00 [ 144.134745] sd 0:0:0:0: [sda] Write cache: disabled, read cache: enabled, doesn't support DPO or FUA [ 144.152487] sda: sda1 [ 144.156442] sd 0:0:0:0: [sda] Attached SCSI removable disk ^C ubuntu@ubuntu:~$ sudo mount /dev/sda sda sda1 ubuntu@ubuntu:~$ sudo mount /dev/sda1 /mnt/ ubuntu@ubuntu:~$ ls /mnt/ '1 Unit 1.mp3' 2.nshEFIFlash.efi Fpt.efi M.nsh SKL_DT_AIO_RVP_KSC_v01_04.bin 'System Volume Information' fparts.txt 1.nsh BOOTEX.LOG FCNTRL.BIN

** Description changed: On RPI4, if you set up netplan to use wifi, and plug in a usb3 storage device to one of the 2x usb3 ports (the ones closest to the ethernet port), wifi will sudden stop working.
