DSL - A modem is a modem is a modem, right?

    In the config I am working with I have a UHP DSL Modem (Earthlink
    supplied) connected to a 11b/g wireless router.

    Repeatedly (and often) the modem enters this 'diagnostic' phase where
    is blocks internet access and displays Earthlink's "Fix and/or Retry"

    - The modem is currently in DHCP/NAT/PPPoE Mode, I'd like to disable
    this and have the Router do the PPPoE dialing.

    - The modem is supplying DHCP to the Router. Seems it would be better
    to hard code some static IPs in there between the Modem and the
    Router, right?

    - re: the Subject Line, I have another, extra, DSL modem at hand and I
    am thinking to swap it out to divide and conquer the 'problem'. Any
    problem(s) with swapping DSL modems like lego blocks?

    Well, I _am_ running the PPPoE via the router now. I just let the IP
    numbers etween the router and modem take care of themselves.
    Yeah. Thx Jeff, so far with the modem in 'I'm only a modem' mode all
    seem well, no swapping to report as of yet.

    Yeah, sorry, I've been less than precise with actual details. I
    changed the modem to bridge mode and the router to PPPoE to do the
    connecting, etc.

    I'm just posting quickley tonight, more details in another thread.

    This may or may not be applicable, but I installed a rwifi outer on a
    Verizon DSL and discovered that the DSL modem was a one port router.
    To get things working, all I had to do was change the default address
    on the wifi router I was installing. That router had a mac clone
    feature, but I didn't need to use it.

    What I was hoping this thread was going to cover is quality of DSL
    modems. Pretty much you use what the ISP "gives" you, but certainly
    some DSL modems work better than others in terms of bit error rate,
    etc The Prestige modem I got with Covad would hang once in a while. I
    complained to Speakeasy, which sent me a "free" modem from Creative.
    No hang conditions, but the power on reset internal to the modem is
    crap cubed. Get a power glitch and it can't restart. I have a few more
    months before my contract expires, that is, I can't dump Speakeasy
    unless I want a bill for that piece of crap they sent me.

    It's an analog world, dammit! Quality is not a feature checklist.

    Asa you probably know, the wall-wart is farmed out to China. It is the
    one piece that could get a company in serious trouble since it
    connects to the AC line. Best to let some other vendor deal with the
    wrongful death lawsuit. Oh wait, sue a Chinese company. That won't

    The broadband review site didn't really have want I want. I'd like to
    see bit error testing at different SNR. Yes, I ask for too much.

    Too bad the FCC isn't purging political appointees with no radio
    communications experience, much less anything the FCC is mandated
    to regulate. At one time long long ago, most of the staff had
    a radio amateur ticket.

    Funny thing is my most dependable DSL setup was from Direct TV, the
    old Telegy (Telogy?) out of Cupertino. Unfortunately, the modem
    didn't work with other ISPs. Also unfortunate that DiectTV decided to
    can the company after buying it.

    Yeah. (I'm the OP) I was also hoping for DSL modem lists of have and
    have nots, quality wise.

    And yeah, I understand about posting in a wireless NG, but I get my
    networking from a wire, before it goes wireless.


    Well, my follow up so far is that by removing the duty from the DSL
    modem to provide both connectivity and DHCP to the router (I believe
    it's in BRIDGE mode now) I have avoided the 'Earthlink is going to run
    diags now..." bullshhhhh it got to doing every night.

    So, I never got around to changing out the other DSL modem after all.

    Not that I know what the VPI/VCI is, but how do I change it? Somewhere
    in the path, I have covad as a provider, with Speakeasy essentially
    reselling the bandwidth, if that makes a difference.

    Well yeah, I did the google first, saw the number of hits, and

    Mine is just a modem, not a modem router. I don't have it at hand for
    obvious reasons. It is the model that had both ethernet and usb.

    Just a FYI. Fry's has the Diamond dsl602e on sale. $44 in the store,
    plus there is a $15 rebate. The good or bad news is it uses the TI
    chipset, AR7 to be specific. I say bad because some claim there is a
    bug in the TI chipset, as shown here:
