No Default Gateway

I've got a problem similar to this guy: http://www.computerforum.com/189722-cannot-ping-win7.html

Wired Router: Linksys RT31P2
Wireless Router: Linksys WRT54GS

I'm trying to Port Forward. I understand Linksys routers use 192.168.1.1 as their default IP. However, because there are two routers, I think one of them might be a different IP. Here's a picture of my cmd-->IPConfig

and here's me pinging 192.168.15.1 successfully and getting a timeout with 192.168.1.1 .

So, you'd assume that I'm running off of 192.168.15.1 . I went in there, changed the recommended settings, and opened a port for my program. I went back into my program, tested out the port and it gives me funny messages. The first time, I let it test both my bandwidth and network. It gave me an error with both. The second time, it didn't give me an error with the bandwidth, but told me my port was still closed. Then, I disabled the bandwidth test and it gave me a network error.

Which router are you actually attached to? I don't think you can actually access the other router without configuring the second router to allow it through.

You may want to change the ip addresses so they are like so.

first router - 192.168.1.1
second router - 192.168.1.2
 
I'm confused with this gateway thing, because the only gateway a router should have is a modem unless you are using one as a bridge. The gateway on your computer should be the same IP for the router you are connected to.

So with that said, you can access one of your routers via 192.168.15.1? Assuming that is the router you are hooked up to, you should change the gateway on your computer to that address.

Edit: You could try disconnecting 1 and configuring them one at a time. Making sure each assigns itself a different IP address from the other to avoid conflicts and most likely where your weird message is coming from.
 
I have a WRT54GL (with Tomato) and a cheap speedstream broadband modem, and I can access the modem's config pages just fine without any extra configuration. All I had to do was to go to my router's (WRT54GL) settings and find its default gateway IP (which in my case was 10.1.1.1) and use it to get to the modem's settings.

I have the wrt54gl and a linksys modem and I can't access the modem login page.
 
I'm really not so great with software/networks. Could you guys help me through step-by-step? I'm assuming we're going to start with the 192.168.15.1, no?
 
I don't want to derail ScottALot's thread but isn't a DSL modem a dumb device. All it's doing is changing the incoming line (eg phone line) to digital. It's no different to a cable coming out of the wall. You simply connect the router to the modem, normally supplied by the ISP/phone company to protect their lines. I have a modem router so it's not an issue!

Edit: To add some useful comment, the physical configuration has not been posted as requested by johnb35 in post #2. In addition I ask why there are two routers? That may be related to the physical setup.

The other "cannot ping" thread turned out to be including a leading zero in the IP address which Win7 does not seem to be able to handle.

Honestly, I don't think there is any alternative to DSL here... our Charter ISP sucks pretty hard (it steals bandwidth from people when someone else needs it because they don't have enough to cover the whole city).

I'm not sure. I think we ran out of physical ports on the wireless one. I wasn't the one that set it all up, it was either our ISP or my dad.

Ah, so I was right in creating my own thread :D

Still not trying to derail the thread! My comments were related to the question of whether the modem settings could be accessed. All I was saying is that I thought the modem was a dumb (transparent) device to the user and you can ignore it. You only care about your router; the router that is connected to the Internet being the gateway.

Thanks for the other replies. Now the layout is known I'll leave it to others to give the best config (but I'll be watching in case no responses).
 
Yeah I don't know if this wasn't understood before... but our cable goes through a modem and then into a wired router. The wireless router plugs into the wired router. I still have to figure out which one I'm hooked up to (I guess that's what's important...)
 
I interpreted your earlier description being that the wireless router was connected to the Internet and the wired one was added due to lack of ports. It doesn't matter which is which, other than to make it easier for someone to refer to the "wired" and "wireless router" rather than "the one that's connected to the Internet" and "the one that's not connected to the Internet"!
 
To jog things along, it's not even clear whether all the PCs and routers are working (whatever the settings) and all PCs can connect to the Internet.
 
ScottALot:

The simplest solution to get all ports forwarded to your wireless computer. On such a complex setup, your best option is to use DMZ.

Start by accessing the router that's directly connected to your modem from a hard wired computer on it and enable DMZ with the wireless router's IP as the destination.

Then go on your wireless router's configuration from your wireless computer and enable DMZ towards the wireless computer's IP.

That all being said, it wouldn't hurt you to hire someone to configure things properly as this setup will always cause you headaches each time you have any connectivity issue to troubleshoot.
 
Well I need to do this all by myself. Now, the wired router connects directly to the modem. The wireless connects to the wired. I think my Xbox is plugged into the wired one. If I unplugged it from the wired and put it in the wireless one, would I need to change anything with the Xbox? Would I get a significant increase in lag? Because if I did this, I could plug my computer into the wired and wouldn't have to go through two levels of routers to forward my port.
