Dual Networks

[DustyV]

I don't know alot about anything, I know alittle bit about alot of things. That's how I get in trouble.
I've had aLinksys E3000 router network at my motel for a couple of years, everything was working fine for a long time. Just moved into a house and ordered Time Warner for TV, Internet & Phone. Ok, the box they gave me was a router & phone connection. I told them I already have a couple of networks running and didn't want the router. Had to use it anway for the phone. I don't want the phone but the whole package was cheaper with the phone. OK, so now I have the TW router. The cable guy said just to run my old router to the new one. I did, it works but now I can't access the E3000's set up page. I assume that's cuz it's going through the new router (which setup I can access). I would just take the new one out but I'd need a cable with cable connector on one end and ethernet on the other or some type converter. Can't find one. Anyone have any ideas how to make these 2 routers play nice together or how to get the E3000 to get cable?
As usual, comments orflames are welcome.
Tnx,
Dusty

Are they both set to the same IP address perhaps? It shouldn't cause any issues when you connect the old router WAN port to one of the new router's LAN ports as long as both routers give an IP address from a different subnet. Say, new router 192.168.2.0 and old one 192.168.1.0.

Thanks for the reply. As it sits the router addresses are:

TWC = 192.168.0.1 (main)
E3000 = 192.168.1.1 (2ndary)

I can connect to the TWC router setup but not the E3000
Just for S&G I ran speed tests. The E3000 clocks at 36.8 Dwn & 6.4 Up and the TWC clocks at 16.8 Dwn & 4.6 Up. That does not sound right to me but then, what do I know <grin>

Tnx,
Dusty

Hmm, did you try https as well? Sometimes happen to cause issues if you use http.
Currently it is: Internet - TWC - E3000, right? What is your PC IP when connecting to TWC?

Try removing E3000 from other networks and only connect the PC to it. Does it connect now?

 

[DustyV]

The TWC modem/router has to be the main because it has the cable connection.
The way it's set up right now the TWC is main and a cable runs from one of the mains Ethernet ports to the Internet port on the secondary router (Linksys) I've been reading (oh-oh he's thinking again) maybe I need to run the cable to an Ethernet port on the secondary and not the internet port? BTW https makes no difference. Oh yeah, I don't know if it makes any difference or not but the computer is wired to a main router Ethernet port. IP 76.178.131.78
Tnx,
Dusty

My Linksys would stop responding to http requests sometimes, then I would have to power cycle it. However, once power cycling didn't fix it and I had to factory reset it (check the manual, something like push the pin at the back for certain amount of time etc).

I'm a little puzzled about how you have things set up, but my guess is that the E3000 isn't routing your PC traffic from its internet side, basically*. (and you might not really want that...)

Did you have two subnets before adding the TWC? (the two being 192.168.0.0 and 192.168.1.0 that you mentioned)
If not, do you want it like that for any reason?

I'm also a bit puzzled as to why your PC has a public IP address (76.178.131.78), or do you mean to say that IP address is the internet-side of the TWC?
I'm in the UK and wouldn't know a TWC router if you threw it at me, but it still sounds odd. Type ipconfig into a cmd window on the PC to check.

I'm guessing that you don't really need/want two IP subnets, and that you just want to use the E3000 as a switch to plug more kit into, or for its wifi. If so, yes you most likely should plug the TWC into an ethernet port (not the internet port) on the E3000. Then, give the E3000 an IP address in the same subnet as the TWC and you should be able to talk to the E3000 through the TWC.


*For you to be able to communicate from one subnet into another, you need a router, but you also need the router to know specifically about the subnets and that it should route between them. Perhaps your E3000 is doing that if the internet-side interface where you have connected to has been given an address by DHCP from the TWC (if it hasn't, then it's almost certainly not). If so, then it's probably the firewall in the E3000 preventing what it sees as 'outside' traffic trying to get 'inside' - exactly what it is designed to prevent.

Rick, you are only confusing OP at the moment. What you say is correct but OP can't open the management interface so can't disable DHCP (which is an essential step in such a configuration) and can't change the LAN IP. He should try it after gaining access.

Regarding, routing info - the current config should work, no need to open anything or change routing.

Dusty, are you absolutely sure you are trying the correct IP to open the interface?

 

[DustyV]

Yes, I think that's what I'm trying to say <confused grin>. I can't access the setup pages for the secondary router (Linksys) to change the DHCP setting (and SSID, passwords Etc.) Yes, I'm sure of the IP's I'm trying to connect to;
Primary = TWC = 192.168.0.1 Can connect to setup
Secondary = Linksys = 192.168.1.1 Can not connect to setup

As it sits right now everyone is connected to the Linksys router with no problem. It's working as before for them. I just need to change passwords Etc. I doubt that it makes a difference but I'd better throw it out here. My main computer is connected via an Ethernet connection to the main (TWC) router so it's independent of either network. It's just more of less the "control module" so to speak.
Tnx,
Dusty

Alright, makes more sense now. Please move the PC to a LAN port of Linksys or use another PC which is on LAN of Linksys. Currently, you are trying to connect to it from the WAN port and actually trying to remote manage, which is by default disabled. Once in, you can enable remote management but best is to follow Rick's advice: set Linksys IP to 192.168.0.2 and disable its DHCP. Then connect Linksys LAN to TWC LAN port. This way Linksys will act as a switch and access point.

 

[DustyV]

Thanks, that sounds reasonable. I'll give it a try when I get back into town on Friday. I'll let ya know how it turns out.
Tnx,
Dusty

Idisconnected the PC’s Ethernet from the LAN port on the TWC (primary) routerand plugged it into a LAN port on the Linksys (secondary) router. Still can’t connectto the Linksys’s management pages. I still get the “page cannot be displayed”message. I’m stumped. You post made more sense than any other so far. I’m readyto toss the whole thing into Lake Coeur d’Alene. Lol, that or buy a cheap cablemodem and make the Linksys the primary (read only) router. Just one morethought (oh-oh, there he goes thinking again) Maybe if I disconnected the cablefrom the primary router to the “Internet” port on the secondary router toaccess the management pages?

Sorry, very tried from traveling,

Dusty

When you connected the PC to the Linksys from the LAN port, did you check if IP was from the same subnet of Linksys?
- Make sure PC's IP is on auto and once connected to Linksys run in cmd:

ipconfig -release
ipconfig -renew

This should get an IP from Linksys DHCP (if it is working). Also test whether you can ping the Linksys.

If still no go, try factory resetting the Linksys.

Another thing to check is read the manuals and learn which subnet both routers use by default. (Sorry if this was already covered, didn't check the 1st page )
