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.

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:

It depends how your provider initially set this up and how you want to set it up.

The setup you allude to is where the ADSL modem is connecting to your provider as well as routing and taking care of DHCP, etc.

A preferred setup is where the ADSL modem simply handles connecting to your provider. Often this means the router has to be configured to do PPPoE, authenticating to the provider via the modem. The router can then handle DHCP, NAT, filtering, port forwarding, etc. Sometimes this setup requires setting the modem to some sort of pass through mode.

Post your exact device information for better help.

Your instructions are correct, but you'll also want to disable NAT on the modem.

You may be having an IP conflict. Did you release your DHCP IPs from your client machines before installing your wireless router? Maybe you assigned your wireless router a 192.168.x.x IP that was in use by another device.

Without knowing what devices you use: if one of them (preferably the wireless router) supports "bridging mode" then that device can be thought of as being some kind of "slave". The other device will then take care of assigning IP addresses and the routing; the "slave" will just take care of passing everything to that device. This will solve a lot of problems in one go (like "double-NAT" issues).

Unfortunately, the term "bridging" is used in many different meanings, like an Apple AirPort Express can act as a bridge in three different ways:

  • If you have an existing wired network, it can bridge this network to wireless clients. (This is what you want.)
  • If it is set up as a WDS remote or relay station, it can bridge the wireless network to wired clients.
  • If it is set up as a WDS remote or relay station, it can bridge the wireless network to wireless clients (or "wirelessly extend" the range of the network).

So: we need more details to tell you the name used in your situation (or maybe point you to duplicate questions here at Super User).

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!

Connecting BSNL(ADSL) modem to wi fi Router(Netgear)...At First Configure your Modem with your PC/Laptop. After login with your User Name & Password( which has been given from your service provider),connect Internet. If it is O.K.,remove cable from modem and connect in your wi fi router, then login in your wi fi router(Cable modem)with User Name"admin" & Password- "admin or password". In internet page, just change to "internet IP Address from static Address to "Get Dynamically/Automatic", after that change "Domain Name Server" from "Use these DNS" to "Get Automatically from ISP". I have done these method and successful.

  1. Make DSL Server the router and in the LAN setting make DHCP enabled
  2. Make the wireless "Bridge" instead of "Router" in WAN setting, and disable DHCP for its LAN settings
