Dlink DSL 2500u v2 Questions

[tp3to]

Hi guys.

I have a question regarding my modem.

Say for ex you have two ISP's. Instead of replacing each ISP's information every time you want to switch over. Can't you maybe instead insert both? So if one is slow just click to enable? Maybe even better, go over automatic if the primary ISP goes dead?

I just want to find the reason why you can put in multiple ISP information in this modem and what the benefits would be?

Unfortunately I don't know of any ADSL modems that allow you to easily switch between different ISP's, except perhaps the ones with 3G failover.

You should be able to simply Enable/Disable those PPPoE connections using the Edit button, but I think the modem would still require a restart.

There are scripts available for splitting traffic with the D-Link ADSL modem on this site or its thread.
I'm fairly sure that you should be able to modify the script so that you can easily toggle between accounts without rebooting the router. All you need to do is delete the default route and then add it to the one that you want to be active.

Determining whether the ISP's connection is offline isn't an easy task, especially if you can't prioritize like ping packets and limit the other traffic to like 80% to allow ping response times to remain lowish.

I know this isn't really a solution, but I took a backup of each ISP's settings so that when I want to change ISP's I just do a restore of the relevant backup.

If you're the only person using the ADSL modem, then putting it in bridge mode and then dialing the ISP accounts from your PC would be the best & easiest option.

Restoring backups on the ADSL modem is a bad idea in general, because its persistent storage has a limited amount of write cycles - not that you would easily exceed it though

can be done on some routers via ssh, but that's beyond general scope/accessibility. but yeah can be done, tho its easier to just set up a server or proper router...

I guess you would need to have some ADSL modem in your "router" (read box with multiple NICs) and some script to flip configurations between ISPs.

Intuition says no, but, is it possible to have two ADSL modems on the same line (ie: same copper pair) ?

You can't have 2 ADSL modems on the same telephone line, because the ADSL modems will try to operate on the same frequency ranges, which simply won't work.

All of the ADSL modems (that I know of) also include a router, but their routing capabilities differ quite a lot!
The D-Link DSL-2500U has a terminal and you should be able to run a script in Windows/Linux to switch between ISP accounts.
I have previously posted links in this thread to where you can find scripts for it...

Why not just create multiple PPPoE connections in your OS, can't be easier, takes seconds to switch accounts.

Why don't you just use PPPOE dial-up from your pc instead then you can choose whatever you want to use without going into the router and trying to setup everything

 

[ichigo]

You must also put your router in half-bridge or bridge mode I think to use PPPOE, although sometimes it is already setup on some routers

Thank you for all the replies guys
