Router to Router

[Vict0r]

(netgear WGT624) Router A- connects to modem
(netgear RP614v2) Router B-connects to router A
Router A: LAN adress: 192.168.0.1
Router B: LAN adress 192.168.0.10 (outside of Router A's DHCP range)
Subnet mask is 255.255.255.0


OK. I want to connect my Router B to A. But when I do the Wireless Cards on Router A cannot get internet. The computers connected to Router B all get internet, but the Wireless Card on Router A doesn't. Does anyone know why this happens? and help me solve it.

Thank you

If you're doing site to site VPN tunnels..you want the networks at each location to be in different IP ranges.

For example..
Site A 192.168.0.xxx
Site B 192.168.1.xxx

I am not doing VPN i just want to be able to connect more PCs to the network.
So router B should have ip of 192.168.1.xxx? and router A should be left like that???

Oh..in my speedreading..that's what "router to router" tends to mean with me.

OK..so you are running a router inside of another router..double NAT'ing. Not my ideal choice of doing things...but still, the same rule applies.

A router connects networks. It has a network on each side of it...in the case of common broadband routers, you have the LAN..the inside. And you have the WAN..generally the internet.

It needs to distinguish between the two. Thus..each network should be different on each side..else..it doesn't know which way to go..it'll be chasing its tail in circles of both networks are the same on each side.

What you wanted to do..was add an "access point"..to your existing router...not necessarily another router. You can get the wireless running as a router..change it's LAN IP to..192.168.1.1...leave the WAN set to obtain auto...and those wireless clients will have internet access going out through both routers. Networking between them won't happen easily..if you're doing file 'n print sharing. But basic internet stuff..most of it will work fine when double NAT'ing.

Ideally what you want to do..is flip your wireless unit to an "access point". I don't know if Netgear firmware supports this..most Linksys and Belkin units do. Look for that feature in the web admin, probably somewhere around advanced wireless configuration. Then..change its LAN IP to one in the same range as your main router..but a unique IP, outside of the DHCP pool. If your main router is say..192.168.0.1...make the wireless one 192.168.0.253. Apply. Now...log into it..on the new IP address..and disable DHCP. Apply.

Now...uplink the wireless unit..to your main router..using a LAN port on each of them. You will not use the WAN port of your wireless router. You may need to use a crossover cable, or an uplink port..depending on your routers.

Now you're using your wireless router..pretty much just as an access point..not even utilizing the routing part of it.

My main router is the Wireless one. K here I will draw a diagram to represent this

Now tell me what changes I need to make?

Based on your diagram, what you are describing..shouldn't happen. The primary router should not be affected by the secondary router..no matter what IP ranges each is.

Question though....why router B then? What it's purpose? Just to extend your network to more PCs? In that case...a simply switch is all you want.

Or are you trying to segment your network somehow?

Bottom line though..the rules of having each router on its own IP range still applies....you should not have both routers on the same IP range.

Well I am doing this, because Router A is in my basement and it connects 2 PC wirelessly. And from one of its LAN ports it connects another PC (PC3 in diagram). So i want PC 4 to have internet as well but i don't wanna buy a wireless card or run a second LAN cable for the PC 4. So I have a second router and I thought of using that to connect my 2 computers upstairs with cables.
And I cannot move router A. It has to stay in basement.

EDIT: WHen i change Router B's IP from 192.168.0.1 to 192.168.1.1 I can't access it anymore when I type 192.168.1.1 into my browser. Help PLZ
I'm not great with networking
Anyone???

Can some1 help me out:confused: :cry: :(
