How do I unbreak router?

NeonSpyder

<div class="IPBDescription">Why do I keep coming back here for tech support...</div>Hokay, I'll make this short and sweet. I borked my router while attempting to get a different router to work.

Essentially my situation is that I have a cable modem which works fine, a Linksys SPA2102-r VOIP router which works correctly except this is the router I was trying to alter. I then have a second router which has more then the input/output connections of the first router, but this is the one I broke.

While attempting to get my routers to work together in such a way that I could set my PC as the DMZ host, I managed to disable the routing function of my second router, I can no longer connect to it's default 192.168.1.1. address.

The *how* of how I broke it was thus:

I turned DCHP off for the second router but kept it on for the first router (ip 192.168.7.1.) I then attempted to change the IP address of the second router to 192.168.7.2, however it gave me an error related to my having the WAN network on the second router sharing a subnet mask (I believe it was a subnet mask) with the LAN network (the one I was trying to change.) The WAN address was peculiarly already set to 198.162.7.3.

So, after it gave me that little error about sharing a subnet and promptly restarting the router, I now cannot access it at any of the above IP addresses or connect to the first router (linksys) through the second router (borked one).

Any.. uh, suggestions?

*bows at the wisdom of the mighty NS off topic forum*

(Hmm, anybody else notice a lot of those "My stuff is borked, yo'!" threads lately?)

Press the factory reset button on the back?

Edit: You might need a paperclip.

Okay, the router is now once again in an non-broken state, I thank you. However I am still without properly configured internet-ness so I must continue my quest of router breakage and un-breakage until I figure out how to do what I want without breaking it. Oh the joys of technology!

Thats a dodgy network setup you got going there... Am I to understand you have something like this?

Intarweb > cable modem > router1 "Linksys" > router 2 > computers/laptops and what not, why 2 routers?

Also what is the problem with the internets? DOes your router "Linksys" have an IP adress and all the DNS names and servers on the status page? If not you might want to do a DHCP release/renew

I almost posted the same thing. This setup doesn't make any sense. What gives?

NeonSpyder

You're right Kouji, that's how the network is setup. Now this is obviously not my preference, but because I'm using a VOIP phone I need to connect the first router directly Internet -> cable modem -> VOIP router.

Problem is, the voip router has only ONE network input and ONE network output, so I have to channel the network into the second router which is my old one (which is now working properly)

I did a bit of digging, and I think the best way to make this work is to just turn the second router into a makeshift hub.

Internets work fine for the most part, the only problem is for pretty much everything that uses TCP or UDP. Every game I try to play online will timeout after 5-10 minutes while everything else online will remain connected.

the VOIP router (linksys) is properly communicating with my ISP. The voip router is running DHCP and is properly connected with all the proper DNS information. I'm using this network to type this right now, but if I were to try to run a game in this setup it would DC because I haven't figured out the right way to do this yet.

I'm in relatively unfamiliar territory here, I'm rather used to configuring a single router to do what I want, but having two routers trying to work together is a bit of a hassle... I've turned off DHCP on the second router and it still works, so that's really nice. But at the moment it's like this:

Linksys 192.168.7.1 -> second router 192.168.7.2 WAN || 192.168.1.1 LAN, with the default WAN gateway to 192.168.7.1 (first router).

I've set the first router to set the second router's 192.168.7.2 address as a DMZ so ports will be forwarded to it, and I've told the second router to set my local IP address as the DMZ. So it's First Router (7.1) -> DMZ'ing the second router (7.2/1.1) DMZing my local IP (1.102)

Man technology is hard <img src="style_emoticons/<#EMO_DIR#>/confused-fix.gif" style="vertical-align:middle" emoid="???" border="0" alt="confused-fix.gif" />

Um.... thats basically the entire internet dude. I mean, theres ICMP I guess, but thats not worth much on its own.

We also have a voip router, but since it is provided by charter (as is the intertubes) it connects directly to the cable so its on its own separate network.

Your description of the configuration sounds right (as right as this setup can be anyway, what with the dual NATing and all). Are you sure thats how this thing is supposed to be used? Who's service are you using?

Edit: Ok so I looked this thing up, and it might be possible to do it like this:

Interblag -> Cable Modem (not actually a modem, but thats irrelevant) -> Non-voip router -> You on port A, Voip Gateway on port B

You will have to enable STUN in the SIP settings page, which will require a STUN server's address that you'll need to get from your provider.

Replacing the 2e router with a switch or disabling the router functionality of the 2e router seems to be the easiest solutions.

Having 2 Routers in the same net is bound to cause trouble!

A router always connects 2 logical subnets. Gateways are for physical ones.

WHat you want could be solved by the following setup:

WAN->Router->Switch->VOIP ATA & Other devices.

That would be the hardware setup.
Now assign your subnets and put the ATAs IP in a DMZ. Tada good to go.

NeonSpyder

I threw away the second router and bought a switch. Everything works now.

Of course it does. Switches are made of win and awesome.

Nooo, switches are made of multiple bridges on steroids.

Now someone give me a good paint representation of that mental picture...

Edit: Another thing:

Most homeuser routers are preconfigures to act as a dhcp server. So by plugging 2 routers into the same net you have 2 dhcp servers fighting over control <img src="style_emoticons/<#EMO_DIR#>/biggrin-fix.gif" style="vertical-align:middle" emoid=":D" border="0" alt="biggrin-fix.gif" />

They weren't in the same subnet, one was in the other's subnet. He configured the one on the outermost subnet for static addressing anyway, but if he hadn't there wouldn't be any conflict because the otermost router is on a different subnet than the PCs.
