Need Internet with WRT54GS router

Hey everyone - I have 2 privates subnets : one (192.168.0.0) for my wire network and Internet, and the other (192.168.1.0) for the wireless. I want to setup a wireless network with a linksys WRT54GS router and have access to Internet.

SHEMA

(X)-------------------------(X)__________________(()) Router A (wireless) Router B (wire) Internet

192.168.1.0 192.168.0.0

Note: Router A address (WRT54GS) : 192.168.1.22 My internet is plugged into Interface 0 (Internet)

I already set the configuration on the router and the communication is established with the wireless network. My problem is when I'm trying to browse.

From the administrative tool of the WRT54GS I can easily ping or traceroute, for example

formatting link
(64.233.161.104), without any problems. BUT on the DOS console (cmd), if I try to ping google or whatever I can't get a response from the destination

I get this error when I'm trying to ping

formatting link
in the console prompt:

1) Ping request could not find host
formatting link
Please check the name and try again

I know this mean that there are no communication with the DNS

2) It's not better doing this: Ping 64.233.161.104 : request time out

3) 192.168.0.9 (DNS) doesn't work either

However when I type Ipconfig /all into the console, it gives me this stuff and find also the DNS

IP Address. . . . . . . . . . . . : 192.168.1.100 Subnet Mask . . . . . . . . . . . : 255.255.255.0 Default Gateway . . . . . . . . . : 192.168.1.22 DHCP Server . . . . . . . . . . . : 192.168.1.22 DNS Servers . . . . . . . . . . . : 192.168.0.9 203.108.60.11 203.108.60.12

I'm aware that my wireless and wire networks are in 2 differents range of IP and it's probably the reason why I can't get internet with the wireless device.

Remember that all works fine on the router. I am able to ping or traceroute google or my DNS. It's only with windows and my browse that I can't access Internet.

Any help would be greatly appreciated, I really need a solution

tyvm all

Finally here is my router config, if it could help

Why are you creating two subnets.

I have two Linksys WRT54GS connected toether with one connected to the Internet and they are both on the same subnet. Reem ber the 4 wired ports on the WRT54GS is a Ethernet hub...

Hi my friend, I'm using 2 subnets cause I need to make a distinction between the wire and wireless network. In the case that I only use one subnet, how can I change the value of the DHCP starting IP Address (192.168.1.X) for

192.168.0.X.

I mean, if you look closely in the DHCP router feature, you can see that you can't change the value of the starting address. It must start by 192.168."1".0 . Then 192.168."0".X is not possible. My Internet must come from 192.168.0.0

ty for your answer

You are absolutely correct in stating that the Linksys WRT54GS supports only one DHCP address range.

Please post the Operating Mode and Routing Table for both of the routers

Setup -> Advanced Routing

I think I should create a route in advanced routing through

192.168.0.0. I try several things but it doesn't work.

For example: Route Name : Internet Destination : 192.168.0.0 Subnet mask: 255.255.255.0 Default Gateway: 192.168.0.10 Interface: WAN (Internet)

I never did this before, so maybe i'm taking a wrong path, any advices would be greatly apreciated ty

Here is my routing table as requested

operatig mode router

Destination Subnet Mask Gateway Interface

192.168.1.0 255.255.255.0 0.0.0.0 LAN & Wireless 192.168.0.0 255.255.255.0 0.0.0.0 WAN (Internet) 0.0.0.0 0.0.0.0 192.168.0.1 WAN (Internet)

I unfortunatly dont have access to the other router.

To confirm, you have access to router A (wireless) but not to router B (wired).

IP subnet 192.168.1.0, can you ping any IP addresses in subnet

192.168.0.0 (other than 192.168.0.22) ???

I suspect that the problem is that router B (wired) does NOT have a route to 192.168.1.0 via 192.168.0.22 ...

Why is anything set as wan? I have mine set to lan and wireless, and just start the wireless dh addresses at .101 (wired at .1, seemed reasonable to start wireless at .101, that keeps em seperated)

Do you have two Linksys router in your environment ?

If so then that is a good approach, the OP only has control over one router, but he could place it on the same subnet and use a DIFFERENT DHCP range than is being used on the router over which he does not have control

and yes connecting it to the LAN & wireless interfaces would be the way to go in your topology

I'm not sure you can do that with the LinkSys firmware. However if you switch to the Sveasoft firmware it's fairly easy to do. (I haven't checked to see if HyperWRT firmware supports the GS model, but if it does it would be even easier.)

The problem is the way LinkSys automatically manipulates the route table. With the third party firmware you have total control of routing as you can add or delete after the Firmware does its thing.

Getting your routes to survive a reboot is a little convoluted, but not actually difficult. (It's fairly obvious to anyone who has experience with unix systems administration, and probably not at all obvious otherwise.)

I use one WRT54G that has a default route to 192.168.0.2 (a firewall router that is the LAN interface to the Internet), connects to the LAN using the ethernet ports rather than the WAN/Internet port. That network does not use DHCP on the wireless, but all of the static IP addresses are in the

192.168.1.0 subnet.

With proper routing it can be configured for a number of different connectivity options.

1) All 192.168.0.0 and 192.168.1.0 addresses can communicate, and all have access to the Internet. 2) Any of 192.168.0.0, 192.168.1.0, or the Internet can be isolated from the individual wireless (192.168.1.0) addresses.

Sure you can.. I'm looking at the screen right now , and where it says "Starting IP Address" (below the local IP address which can also be changed)..

Router IP Local IP Address: 192 . 168 . 1 . 1 Subnet Mask: 255.255.255.0

--------------------------------------------------------------------------------

Network Address Server Settings (DHCP) DHCP Server: Enable Disable Starting IP Address: 192.168.1. 100 Maximum Number of DHCP Users: 50 Client Lease Time: minutes (0 means one day)

Now that I think of it, have you updated the firmware for that device? The lastest (and an installer) is dated 01/03/2005 and is available at.... go to

formatting link
the right side click on Firmware, and you will get a page that starts with (in HTML of course instead of text...

WRT54GS - Wireless-G Broadband Router with SpeedBooster v1.0

Firmware Date : 1/3/2005 Firmware File Size : 3.43MB Firmware Version : 3.37.6 Click here to download the firmware file.

Click here to download the version information.

================================================= Update your firmware and look again... There will be square blue boxes around the numbers that can be changed.

Then you need a D-Link 614+ router. That is the number my router starts with 192.168.0.1

Tyvm all for your answers,

I solve my problem !! Instead of using 2 subnets, I only use

192.168.0.0. I finaly have been able to change 192.168."1".0 for 192.168."0".0 on the DHCP feature of the WRT54GS router. I also use the router as a hub now. I can easily determine the wireless network by the range given by the router

ty again for your answer
