connected to a network but can't browse net in vista

[frozenfire03]

Hi guys,

I am Jerald, IT head in a hardware company. I want to share my problem to all you readers..
I have a desktop computer that has a internet connection, or let's say it is my server.. I am using D-Link Ethernet Broadband Router which has an IP Address 192.168.1.1. This router is not a wireless router. I bought a wireless router named Linkysys.. I configured it using Automatic Configuration -DHCP, with a router name WRT54G.. i used the D-link router ip address as it's gateway (192.168.1.1). I disabled the DHCP server.. in other words, i am using a 2 router, a non-wireless connected directly to my desktop computer and a wireless router connected to that D-LINK broadband router..I tested the connection using Windows XP laptop and by then it works.. I can connect to my wireless network and browse the internet.. On the properties of my loptop wireless network i configured it as "obatain IP address automatically and "Used the Following DNS Server' i used Preferred DNS: 124.217.127.238 and Alternate DNS: 202.138.128.54. I click on the "ADVANCED" button and add a gateway using my D-LInk router IP address 192.168.1.1. Suddenly one of our customers want to connect in our wirless network.. He is carrying a Windows Vista laptop.. I connect it to linksys wireless network but i can't connect to internet. obviously it has an X on its connection to the internet. But if i look on it's wireless connection it says IT WAS CONNECTED, and it displays EXCELLENT on it's status.. I wonder why i can't connect and browse the internet..

Please help me how to configure it, no problem with windows xp..it's on vista alone..

Thank

Jerald

Can you explain exactly how that secondary router is configured and how it's connected to the primary router? FWIW, here's how I connect secondary routers to use as WAPs to avoid the issues of double NAT layers.


Connecting two (or more) SOHO broadband routers together.

Note: The "primary" router can be an actual router, a software gateway like Microsoft Internet Connection Sharing, or a server connection that has the capability to supply more than one IP address using DHCP server capability. No changes are made to the primary "router" configuration.

Configure the IP address of the secondary router(s) to be in the same subnet as the primary router, but out of the range of the DHCP server in the primary router. For instance DHCP server addresses 192.168.0.2 through 192.168.0.100, I'd assign the secondary router 192.168.0.254 as it's IP address, 192.168.0.253 for another router, etc.

Note: Do this first, as you will have to reboot the computer to connect to the router again for the remaining changes.

Disable the DHCP server in the secondary router.

Setup the wireless section just the way you would if it was the primary router, channels, encryption, etc.

Connect from the primary router's LAN port to one of the LAN ports on the secondary router. If there is no uplink port and neither of the routers have auto-sensing ports, use a cross-over cable. Leave the WAN port unconnected!

This procedure bypasses the routing function (NAT layer) and configures the router as a switch (or wireless access point for wireless routers).
