Dlink DSL-300G+ DHCP Server query

    Has anybody managed to change the default lease time from the 20
    second default?

    My SonicWall SoHo2 keeps shutting down randomly because it
    cannot find the DHCP server.

    Have tried changing it using the console, but no joy. It gives no
    error but makes no changes.

  2. No, you cannot.
    Indeed. Report it as a bug to Dlink and they might fix it, if enough
    of us do.

    You've managed to use the console port???? GIVE DETAILS PLEASE!!!!!!

    As for the DHCP leasetime, I took it up with my ISP who (after some to-ing
    and fro-ing) suggested I take it up with the manufacturer. I've taken this
    up with D-Link about 6 weeks ago.... talked to "tech support" who were going
    to investigate it and, if necessary, get me to return the kit... still no
    reply!
    Incidentally, I re-flashed the Modem with the latest firmware from the
    D-Link webby, still no joy!

    Sorry, I should have made myself clearer wrt the console port.
    I actually telnetted onto the modem and used the default password
    of private.

    Have you seen the command set that should be available to us?
    If not do a search for "ATMOS Console Commands Reference Manual"
    Quite enlightening.

    Will call D-Link and complain about their crappy implementation of
    ATMOS.

    I've got the Ref Manual - but I also noticed in those links on google other
    stuff about telnetting to a 604 router by frigging the flash firmware and
    re-loading it. Is this what you did, or have you got better instructions on
    how to telnet to the 300G+ ?

  6. After my experience with a D-Link 504 router the best thing to do with
    any D-Link product is to pick it up manually and throw it in the bin .

    All I did was to telnet to 192.168.0.1 and when asked for the
    password, enter "private"
    The prompt then changed to 192.168.0.1> and I was in....

    However the dhcp server on the modem is a pile of poo.

    Session as follows....


    192.168.0.1> dhcpserver
    192.168.0.1 dhcpserver>
    192.168.0.1 dhcpserver> dump

    Don't know enough about atmos to understand it, but I suspect that
    there is an error in the config somewhere.
    I have been looking at the configs in the flashfs system, but found
    nothing .

    Any suggestions?

    Having just got one of these modems myself, I'm frustrated to say the
    least. My log files are filled with useless garbage about renew/release etc.

    I know zilch about the subject but this list appears to suggest that you
    can change renew times? Having tried a few combinations around time 5000
    5000 etc, it appears to have no effect at all. Dusty bin awaits, I guess.

    Yup, I get the same as you. I hadn't noticed that before.

    If you change the renew times in the dhcpserver section, it seems to
    accept it, but nothing is changed. It still has that crazy 20 second
    renew time.

    It looks as if there is a serious problem with these modems.

    D-Link don't seem interested in fixing it.
    My modem was bought second hand, so I am well and truly knackered...

    If you have recently bought it, I would take it back for a refund.

    I will try a bit more fiddling later today. I wonder if trying to edit
    with firmware with a hex editor will prove any use. I can't return mine
    for a refund either. I don't really mind if it craps out. You live and
    learn and I guess dlink have just lost a customer here. I've also got a
    dlink 804hv router which is actually pretty darn good, but this modem is
    pants.

    Hmmn, nosing around the ip parameter and the device submenu in telnet
    shows the mtu fixed at 1500. Maybe this doesn't matter but my
    understanding is that a lesser one is used in the UK? My isp keeps them
    all to 1460 anyway. Attempts to change this crash the thing.

    Well they *do* work. The only problem with the dhcp server is that
    it fills the logs up. My temporary solution was to change the dhcp
    client I use under Linux to only report changes to the leased IP
    address, with a summary every hour.

    hi I'having dsl modem too, and I'm not very happy with that product.
    I'm trying to access via the telnet with the default password, but it doesn't work.

    can anybody help me please?

    Well, D-Link have told me today that they reckon my modem is faulty and have
    given me an RMA number to return it. Seems a bit mad that, since the support
    guy agreed with me that a lease time of a few seconds was wrong. Surely this
    should just be a firmware update.

    I'm going to talk to them again tomorrow and see what happens. More news to
    follow.....

    Interesting. I've just called them about the same issue and got the same
    reply. I will say that their support line was answered very promptly and
    the guy at the other end was constructive and helpful.

    I agree, their support line is very good, and the people a re helpful.

    Not satisfied with getting an RMA I spoke to someone in 2nd line support. He
    has suggested that I change the Encapsulation setting from "VcMux" to "LLC",
    and report back to him!!

    So far this seems to have provided me with a more reliable connection,
    however the log in my router is still showing lots of DHCP Requests. I am
    going to run it like this for a couple of days, and then do the same without
    my router, and check the lease time on PC, to see if it is the same 10
    seconds or whether it has changed.

    I think it is worth everyone who is experiencing this problem calling D-Link
    and reporting it. The more who do, the more likely they are to release a
    fixed firmware, if that can solve the problem.

    Freephone number is 0800 917 5063, this is for broadband and wireless
    products.

    I just tried LLC. I've also tried PPOE as well. Both appear to work but
    make no difference to the DCHP release/renew according to my DLink 804vh
    router's log which is still at 6 seconds.

    I'm also having a go at rma'ing the router. This has a bug in its syslog
    so far as I can tell and, interestingly for a vpn router, apparently
    fails to encrypt L2TP and PPTP sessions when acting as a server though
    it won't tell you that so your traffic is en clair. A guy in the States
    just discovered this from DLink US support who told him straight up if a
    posting elsewhere is to be believed. Firmware troubles again, they said.
    The UK Dlink support guy was a lot more cagey when I broached this one
    with him. Could just be a BS rumor, I guess. It still makes a darn good
    firewall.

    I agree, my router still has DHCP requests every few seconds, and when I
    connected the modem direct to my PC I got a lease time of, wait for it,
    ......... 30 seconds!!!!!!!

    I am going to keep like this over the weekend, and then call D-Link againon
    Monday, and see what they suggest next.
