A wireless router hooked up to a wired router


Recommended Posts

Hey,

I recently just hard-reset both my routers.

The first router (wired) gets all of my internet config from my host.

The second router (wireless) is supposed to get the config info from the wired router.

When both routers are hooked up I lose my wired connection.

Am I supposed to set up my PPPoe info on both routers? My iPad connects to the wireless but cannot access the internet.

Both routers have the same ip 192.168.1.1 so to access the router through the browser I have to unplug one or the other to access.

I set it up fine a long time ago but I forgot how to set it up.

Thanks for your help.

You have conflicting iP's first of all, make your master router (wired) is192.168.1.1 and the slave (Wireless) be 192.168.1.2 (or any number you want in the same range) - this will solve one issue.

Wireless router should plug into port 1-4 or any open port on wired router to receive signal. But plug WAN on Wireless into numbered port so you fool the wireless into thinking it is getting internet from ISP.

It is up to you if you want to assign DHCP to devices plugged into wired router, but beware - don't conflict them, or they generally cancel each other out.

This is one way to do it, but you will be double firewall / nat-ing when connecting through the wireless router. Which will be fine in most cases if your not gaming or vpning when connected to the wireless.

Normally what I do is set both routers up with unique IP addresses, same as medfordite explained. Then I disable the DHCP server on the wireless router, plug one of it's LAN/switch ports into one of the LAN/switch ports of the wired router connected to the internet. This way your wireless router will pass along the DHCP IP requests from your wired router to your wireless clients. You also will not be going out through the wireless router's firewall, but instead going directly to the wired router, and its firewall / NAT tables.

No -- if you were going to double nat like that, you sure and the hell would not want the same network on both sides of the nat.

abysal gave the correct instructions on how to setup 2nd router as just AP on your current wired network. You would never want to double nat, ever! It complicates the network, and adds overhead for no reason - it can work yes. But you would need want 2 different networks 192.168.1.0/24 on wan and say 192.168.2.0/24 on the lan of the second router.

Please don't do it that way - or your just going to be back here asking why it doesn't work when you want to port forward something behind the 2nd router.

And NO you would not setup PPPoE on both routers.

Runs sheepishly in the corner and whispers *I stand corrected. :blush: *

I was going to suggest disabling the DHCP on the wireless router, but guess I forgot to in real. I have used this type of set up in the past but instead of router, using a PC as a firewall/router using things like ClearOS or Smoothwall.

WOW! I feel pretty dumb now. :)

If you would disable dhcp on the wireless, and connected it to first router with its wan interface - no clients would get IP, be it wireless or wired to the router.

Your instructions were kind of a mix between AP setup, the same network different IP - just forgot to connect to LAN and disable dhcp.

Does not matter what your first nat device is - you would pretty much never want to double nat, the only times you would do such a thing is when you don't have a choice. Say for example first nat router is NOT in your control, say from isp and its a gateway device (modem/router) and you can not put it in bridge mode and want to use a different router/firewall solution. Then double nat can work, just put 2nd routers wan in dmz of first device and then double nat (with 2 different networks on each side of course)

Personally I would just buy my own modem in that case ;) So I could setup the network how I want - or worse case change isps.

Double nat can work - **** I have seen triple nats setup and work. Just WHY??? Is the question.

why can't you just get a nice wired router and then get an access point? That's the easiest thing to do. the router is the DHCP server that way. Also most modem+router combos from ISPs have very limited firmware like the superhubs and you can't alter the NAT or much of the IP settings.
