Using router in "static" mode with a "dynamic" connection?

    My ISP (Charter Pipeline) offers only "dynamic" broadband cable service. I've found that when using my D-Link router in dynamic mode (default setup) I often have problems with false "404" DNS errors (i.e.; "this page cannot be displayed") and/or web pages that download with (red x) place markers where small graphic images should be. Updating my router's firmware to the latest stable version improved it's performance however the errors still occur albeit less often.

    On the other hand, if I switch the router to "static" mode and manually enter the necessary settings, everything works great. Since I seem to be unable to fully resolve the problems in dynamic mode I'm wondering what sort of future issues I'm likely to encounter if I go with static mode on a full-time basis. To be more specific, my understanding is that the ISP will change certain settings from time to time since this is the nature of a dynamic broadband connection.

    With that in mind, my questions are:

    1) What settings will most likely be changed by the ISP?
    2) How often might the changes occur?
    3) Are there any workarounds to minimize the inconvenience?

    My router is a D-Link "DI-624" (Version "C", firmware version 2.42). If it makes any difference, the router has an option to set a "Static DHCP"

    Thanks in advance for any words of wisdom ;-)

    You should not encounter any problems unless your ISP changes DNS servers or if your WAN IP address were to change.

    DNS server changes: Depends on your ISP, min has changed theirs once in 5 years.

    WAN IP Address: Depends on your ISP. You may be better off asking them these questions directly. Static DHCP....kind of an oxymoron isn't it? I have never heard of such a thing.

    Hey that's encouraging.Thanks for the info! If you're curious about the "Static DHCP" I've attached a screenshot jpg of the setup dialog box.

    Thanks,

    Are you settign your local computers statically or the router? If it is your internal LAN then there is absolutely nothing to worry about.

    You're talking about the LAN side, it doesn't matter what you do there, as far as your ISP is concerned. Their interface is the WAN configuration of the router.

    would setting static routing increase bandwith at all?

    Not a bit. The only thing that DHCP does is set the IP address for the lease period of time, then the traffic is identical between the two methods.
