Connecting a ADSL router to a wireless router. What am I doing wrong?

Question

What is the correct way to do it? This are the steps I have taken:

1. Disable DHCP in Wireless router
2. Setup a fixed IP (192.168.1.2) and telling that the default Gateway is 192.168.1.1 (the ADSL router)
3. Plugged the Ethernet cable from the ADSL router to the "Internet" port in the wireless router.

It does not work.

Solution 1

Tried again from zero and works right away (The magic of PCs :)

Things I did:

1. Leave the IP of the Wireless router in automatic
2. Change the internal IP to 192.168.5.1 (I think here was my mistake last time)
3. Leave DHCP ON and starting with IPs 192.168.5.100
4. Presto! All works like a charm in 5 minutes.

Thanks all for answers!

Got a little complicated whilst writing this - 1 refers to your modem, 2 refers to your wireless router.

This is one thing I hate doing as it can change based on device manufacturer and features. Personally, if you can upgrade 1 and 2 and just have one device, you will be better off.

For a start, if your 2 actually supports this e.g. has an Ethernet WAN port instead of a smaller telephone line adapter, you may not even have to disable DHCP anywhere - simply make sure the 1 works (connect it up to one pc) and if it does, plug it in to to the 2, and then it should "just work" - if it doesn't, your 1 is more likely to be an actual router (just with one port).

so, if 1 is actually a router instead of a modem, I would recommend that you see if you can change the mode of 2 and basically disable all routing and change it to an access point, this will then do all the DHCP and everything else at 1 whilst just providing an access point to wired and wireless devices - by far the best way. (After changing this, you may have to first manually set the ip of 2, this will mean that all devices are pingable and accessible on your network and the easiest to manage.

step by step - you seem to have done some of this already, but this certainly works

1. go to the wireless router setup and turn off its dhcp server and set up a fixed ip address to it.
2. connect the wired router and the wireless router - lan connection to lan connection (as odd as it sounds)
3. check if you can access the wireless router from a box connected to the wired router 4) if so test the wired connection, then the wireless.

This worked in a similar setup for me and others

here is a good article, 4 ways to do that. It is very easy:

Is the ADSL device a modem or a router? Your question text and the title seem to conflict.

[Rook]

In addition to what the purple pixel said above, name the model of the "model" (which I'm guessing could be "modem"/router)

[Eduardo Molteni]

I'm trying to avoid bringing specifics models of routers to learn about the process, but I guess it is different in every case. Weird

[Rook]

Actuaally, it's rather similar in most cases. But while learning, it is better to view one specific example (model), than to go "the general route".

superuser.com/questions/104043/… possible dupe BTW. The answer/answer is identical

[Eduardo Molteni]

I've guessed that it would just work, but spend 3+ hours yesterday trying to make it work. The thing that makes no sense is that some say to plug the cable to the standard (numbered) port of 2. I will try to make it an access point tonight

[Thalys]

it makes no sense... but it works. Its something to do with vlans i suspect- that connector is a network segment on its own

[William Hilsum]

@The Journeyman geek, it is not vlans - it is simply subnets, routing tables, NAT etc... it is just the way the devices are designed to "route" information... Routers are designed for two (or more, model depending) networks - typically commercial ones have a built in modem and switch, but if you go back (quite a few now) years, when you didn't get so many "all in one" type devices, you really start to learn what features each device brings - and how they work from a deeper level (Hope this comment makes sense... very tired writing it!)

no, this is wrong. you had the step 3 in your original instructions backwards. superuser.com/questions/116255/… has it right, you need to connect them lan-to-lan. This is why you disable the 2nd dhcp server first.

[user23307]

The instructions are wrong, step 3 should be to connect the 2 routers lan port to lan port, not lan port to internet port.

[Eduardo Molteni]

:confused: Maybe you are right, but this setup just worked (and I will no touch it)
