Networkspeed

  • Is the networkproblems that where in 7020 still in the 7025? I try to flash via the webinterface but in my switch I only see CRC errors and even when I turn down the speed to 10 Half Duplex there are problems.


    The switch I use is a Cisco 2924 XL and it worked with my 7020 as it should but now with 7025 it is impossible to flash.


    My box broken or is the same old problem with 7020 still there?

  • If I use Dreamup and flash the box it works as it should and I am able to flash the box but if I tries to use the webinterface it fails all the time.


    When the image is in place with Dreamup there are no problem with the network but during the webinterface flashing it does just not work.


    Output from my switch on the port conected to my 7025.

  • Looked even more close into this and discovered following.


    Woth bootloader 44 which my box has it never enters 100 Full Duplex mode it just goes to 10 Full Duplex and of course this will give errors when the switch operates in 100.


    Question now, is my box broken since bootloader does not use 100 even when I set it in the "bios" or is bootloader 44 broken???


    /WeeGull

  • So been changing lots of switches at home now and either it is my Dreambox 7025 that is broken or there are a bug in bootloader 44.


    No matter which switch I use the Dreambox runs at 10Mbit Full Duplex and it does not matter what setting I use in Dreambox it always anyhow use 10 Mbit Full Duplex.


    This is in the webflashmode only. If the box boots and Enigma2 starts it runs in 100 Mbit Full Duplex without problem.


    So bug in bootloader 44 or broken Dreambox 7025? Is there anyone who can just enter webflashmode and at that moment telnet to the Dreambox and check which speed the Dreambox use?


    Tested switches,
    Cisco 3524Xl
    Cisco 2924 XL
    HP Procurve
    Netgear DS108
    D-Link DI-624

  • Now I talked with 2 friends that also have 7025 and they do not have any problem with uploading new images via the webgui which I have.


    Will take my box to the store tomorrow and have it changed into a new.


    /Weegull

  • Well, auto in settings on the Dreambox and auto on the switch which result in that I am not able to send new image via the webgui, I dont think that is strange.


    Just been trying with different switches to see if the problem is related to one switch or not. Only way to get a image uploaded is to set the switch in 10 FD and in the Dreambox it does not matter which setting I use it always use 10 FD.

  • Of course I changed cable to the dreambox and even tried to upload the image from 2 different computers. The only thing I so far has not been able to change is the dreambox.

  • okej, my Dreambox got "real" IP but of course a firewall between it and Internet.

    usually in a private Network the ip-Adress starts with 192.168.....

  • It's possible, though i'm not sure, that the speed setting won't always work, or fall back to autoneg in any way. If there is no NWAY support on your switch (some early, expensive 100mbit equipment doesn't, nearly all consumer-grade does), it falls back to 10HD.


    I'll check that.


    I don't think your hardware is faulty. If you want to check that, use linux, and check from there. Don't use the secondstage as a reference for that.

  • Got a new box today and it looks the same in bootloader.


    Is it a typo or do you mean that the fall-back is 10 FD och HD? The Dreambox goes to FD.


    The strange thing is that my 7020 works as it should and operates in 100 FD as it should ( or it did sold it today).


    My thoughs is now that bootloader is little buggy and needs more code from 7020 since that worked.

    EDIT, why fallback if you set the speed and duplex manually? It should not do any other speed than what I manually set otherwise why is there the manual setup?

  • It's just not easy to force the speed on the Realtek 8139, that's all. The code is not completely implemented, that's all. That will change.


    It *was* easy on the network chip used in the 7020.

  • Hi,


    could it be a problem of your Cisco switch?
    In the company where I work we only have Cisco switches and we have a few issues with the speed negotiaten. We then have the same problem with the CRC errors.....
    Our network guys says that is a known problem of Cisco switches in combination with certain network chips.
