DSL doesn't like my router

[comp615]

Just got a new Linksys WRT54g or something like that (Wireless router) and was trying to get it to send my DSL wirelessly. GOt everything hooked up right and I thought it should just work like cable. However, I can get Internet for a few seconds then after a minute or two it cuts out. I've tried disabling PPPoE on the DSL modem and putting it on the router and using auto mode on the router with PPPoE on DSL to no avail. I updated the Firmware on the router because I think it had had some glitchs with DSL and it worked for about 10 minutes, but when I came back....poof. Any ideas on this one?

I'm assuming that you can get the internet while wired to the DSL modem...correct?

Do this:

Connect the computer to the DSL modem, and if the internet works, then do this:
START>RUN and type in CMD. When you get to the DOS prompt, type in "ipconfig" (no quotations.

Take note of the IP address given. Assuming that the internet works, got to www.whatismyip.com and see if the address given is different.

IF AND ONLY IF the addresses are different, you have a modem that is a DHCP server. Your router may also be trying to be the DHCP server. Internet will only work if one of the two of these is doing that job. The solution is to disable DHCP on the router, if you only have one machine connected. Otherwise, you might have to put the DSL modem in bridge mode so that it doesn't do any address translation, but instead just forwards to the router.

One warning, however, be careful to run the procedure I explained above and make sure your outsiide IP address is different from your inside IP. If not, your computer is wide open to the world.

Sry my fault...time for more info.

1. The DSL works fine when hooked directly into the computer

2. The Modem is a DHCP server, however, I could not figure out how to turn this option off so I had to turn the DHCP in the router off.

3. I cannot ping the modem when hooked to the router (or connect to it by IP)...I was told that this was because the computer can't see past the "Default Gateway"....but...

4. Now heres what I think the problem is, the subnet of the modem is 255.255.0.0 whereas the routers is 255.255.255.0 I cannot change either (Modem will not change at all, and router goes to 255.255.255.55 etc, changing only the last number)

5. Even though all of the above, I was in fact able to access the internet with the computer through the router for a short time....soooo?

Is there just one computer connected, or more?

I've had this same problem with a Netgear router and a DSL modem.

If you open a browser and type in 192.168.0.1, you should get some kind of UI for either the router or the modem. That will tell you which one is actually serving as the gateway

Sorry, posted that a little early.

When I had this problem, the Netgear router actually SAID it was connected to the internet, but it really wasn't. I couldn't get it to work with DHCP shut off in the router either.

The solution was to put the DSL modem in transparent bridge mode, and then set the PPPoE settings in the router so that IT signed into the ISP instead of the modem

I hope this is helping you...

Ok, so I looked at Linksys's online guide to your router.

Unfortunately, these situations get kind of complicated, but I've been through this, just recently.

The ONLY way I could get it to work properly was to set the modem to bridged mode and then set up the connection protocols in the router. The easiest way to do that, at least with the Netgear--I would think that the Linksys should be even better at this:

Connect the modem directly to a computer. Reset it in bridge mode. This WILL cut off your internet connection. Shut off the modem.

RESET the Linksys to the factory defaults. There should be a switch on there you hold down for a specified time period to accomplish this.

Shut off the computer.

Connect everything, and turn on your network IN THIS ORDER:

1) Modem, and wait for 2 minutes or so. You will not see the dsl LED come on.
2) Router, and wait for a minute or so.
3) Computer, then run the set up wizard for the router. It should auto detect the settings for internet. You'll need your ISP's user name, password, and you should have the DNS servers handy, unless your ISP feeds them to the modem.

Once you're done with that, your problem should be solved.

One thing to consider: You should go ahead and connect the computer to one of the ethernet ports on the router, rather than do this through the wireless. Once you reset the router to factory defaults, it's going to want to hunt down the computer and connect it. Get it connected to the internet and then deal with the wireless connection. To do this may require disabling the card in your device manager and using an ethernet jack, provided you still have one.

ZOMG triple post!!! Neways, I will try to do that....maybe the wizard will work better. I tried bridge mode and got nothing but that was hand setting the DSL info. Also, Bridged means I should have the router assigning IP's correct? I think I messed that up before :-P

Yeah, sorry about that--got to thinking more about it, and thought of more things. These things can be SO confusing. It just happens that I fought my way through it a week ago and this was how I got it to work.

Yes, bridge mode will allow your router to set IP addresses on your LAN. Right, now, it sounds like they're both trying to manage the LAN. That won't work. You can reset the router to the factory default, meaning that when you power up, it will look to configure itself again.

Also, in bridge mode, you can't set any ISP information. The modem is just a passthrough at that point. That's why you lose your internet when you set it like that. Then the router picks up the modem's dsl protocols (password, DNS server info, etc). The Netgear I use at my office LAN autodetects all that stuff. Yours should too, but you really have to set it to the factory settings again.

1. Switch your modem to bridge mode.
2. Connect it to your router, reset the router to factory defaults.
3. Log into the router (192.168.1.1) and set the router for PPPoE with username and password - keepalive, 20 seconds.
