rpi3 b+ usb LAN adapter issue (to win10 samba)

    Dear community

    I have a weird issue with the new rpi3 b+ and samba. It keeps disconnecting and explorer freezez on win10

    I can see folders but a few moments later it disconnects. (tried to copy, and stream videos from connected external hdd... it worked before with openelec)

    Libreelec version is the newest 8.2.4

    I make min smb to 1, max 3, tried minmax to 3. Tried a different openelec smb.conf, a libreelec smb.conf file from another topic, but cant fix by myselft.

    pls help with a step by step easy description if you know how to fix it!

    thx

    same board, same libreelec version, the same problem... No matter how many data you transfer but after 15-20 minutes it drops off (for ecample: after 15-20 minutes of watching movie remotely vlc stucks and throws "BAD file descriptor" errors) and after 1 minute it is back again. Forcing other SMB versions does not help. Plus I can not use wireless at my home because I have too many wifi active connections around me causing instability and poor bandwidth.
    Former RPi3 B was ok with that but on Rpi3 B+ is the same configuration faulty.
    I am kind of desperate..

    So, is there any known planned fix or we have to report bug?
    And yes... I expect "blocked until raspbian ethernet drivers are woring" or something like that....

    Try 8.2.5 which includes LAN driver and firmware fixes for 3B+.

    There are still remaining 3B+ LAN driver and stability issues which the RPi developers are aware of and actively working to fix. Hopefully these issues affect only a minority of users (those with unusual network VLAN/duplex/cable configurations, or 3B+ boards with slightly marginal RAM chips that may require a voltage bump) and will be fixed sooner than later in software when we will release an LibreELEC 8.2.6 update.

    I seem to have the same LAN performance from 8.2.4 -> 8.2.5. I have two 3B+ units with different modes of connection - 1) Direct LAN via switch 2) LAN via wireless bridge. Both units show odd SAMBA performance as they did with 8.2.4. WinSCP doesn't seem to have the same same dips/crashes in throughput (See attached).

    I believe I would not fall into an unusual network configuration for at least one of my units. I've attempted a memory over volt (over_voltage_sdram=1) with no change in performance.

    TDown I don't know what the graphs represent, are you reading from or writing to the 3B+? If you are writing to the 3B+ then where is the data being written - if SD card, could that be the bottleneck?

    I have the following:

    RPi3+, SanDisk Extreme Plus (32GB), wired Gigabit ethernet, running latest Milhouse LibreELEC 9.0 build (Samba 4.8.0)

    Windows 7 PC with SSD, Gigabit Ethernet

    Both clients are connected into the same dumb/unmanaged 8-port GigE switch.

    I'm able to copy a video file from the RPi3+ SD card over Samba to the Win 7 PC at a sustained rate of about 42MB/s - this basically maxes out the 3B+ network connection, which is the bottleneck.

    Copying the same file from the Win7 PC to the RPi3+ (to the SD card) copies the file at an average rate of about 30MB/s as now the SD card is the bottleneck (it can't write any faster than about ~25-27MB/s).

    I'm using a Class 10 Sandisk and a Class 10 Samsung, 16GB and 32GB in my two units. The graph was copying a video file to the Pi via unmanaged GbE switch. The issue is not max speed, 20MBps is spec. The issue is the constant dips down to 0. I do not experience this with Workstations on the same network.

    I'll test some more and possibly explore different SD cards.

    Tested the new 8.2.5. still not ok :(

    Millhouse, can you please send me that 9.x version of your image file please?


    And how can I raise speed above from 11 mbps on windows 10?

    What component is slow on my rpi3b+?

    -sd :class10 sandisk

    -maxtor 1tb external disk usb3 60mbps speed when connected to pc (maybe this? cos only usb2 on pi?)
