Need guidance to correct a wireless access point setting.

Here is the scenario.
I have a car dealership that I use a SonicWall TZ200 to manage the network.  All workstations have a static ip address and gateway address pointing to the SW TZ200.  When technicians use a pc that has a static IP address, they are able to login to their manufacture's service website and click on a link that gives them information about a specific vehicle's history, etc..
I have a Linksys Wireless G WRT54G2 that I have configured on the network to provide wireless access to 3 laptops in the service bay.
The laptops are taken home at night and do not have static ip addresses.  I assigned a static IP address to the Linksys router, disabled dhcp server and changed the setting from gateway to router.  The technicians who use these laptops can login to the secure car dealer website but when they click on the vehicle history, to get these reports: a new browser window opens and the page starts to load and eventually it times out.  I have tried a new access point, same settings, same result.  Do I need to port forward in the linksys?  I did call Linksys and the tech suggested redoing the wireless security, which I did, ( I turned off the wireless security), same result, no joy.  ANy ideas?

"a new browser window opens and the page starts to load and eventually it times out."

how long has this been happening?

can you access the website correctly on your network elsewhere, not using these laptops?

you should have to port forward anything. this would seem like a website issue or browser related problem.

Evidently it's been going on for a while but they were assuming the problem was with their laptop's browser settings.  You can access the website and the subsequent links from any desktop that is not going through the wireless access point.

I guess I'm missing something.

When the laptops connect to the wireless network, how do they get an IP address?
You say that they do NOT have static IP's set, because they are taken home at night, but if I understand correctly you have turned off DHCP completely  on both the SonicWall (because the machines that connect to it have static IP's, and don't need DHCP) and you've also disabled DHCP on the Linksys.  Is that right?

If you could provide a little more clarity on this, it shouldn't be too hard to figure out what's going on.

But I *think* the way you want to configure things is:

Set the Linksys up as a router.

Give the Linksys' WAN port a static IP address in the range of LAN addresses handed out by the SonicWall, making sure it's not already taken.  So, if the SonicWall gives out LAN addresses in the range 10.0.0.X, you could give it, for example.

Set the Linksys' Gateway address to the LAN address of the SonicWall; so, this would be, if we're continuing with the numbering scheme described above.

Turn DHCP Server ON in the Linksys, and make sure that the addresses it's handing out are not in the same range as the addresses handed out by the SonicWall.  So, for example, you could use 10.0.1.X.

Put universally accessible DNS servers (like and in the Linksys.  (You have to do this, since it's got a static IP address, and isn't querying for an IP address, or for DNS settings, from the SonicWall.)

Now, let the laptops connect to the  Linksys should get their IP addresses via DHCP from the Linksys.  Anytime they seek an IP address that's not in the 10.0.1.X range, the Linksys will hand it off to the Sonicwall out the Linksys' WAN port, since the Linksys' gateway address is the Sonicwall's address.


Turn DHCP off in the Linksys (making sure, though, that it has the SonicWall's LAN IP address as its gateway address, and that the Linksys has a static IP address that's within the range of LAN addresses handed out by the SonicWall) and, in each of the laptops (assuming they're running Windows XP), do this:

Go into Control Panel / Network Settings  and select Properties on the Wireless card.

scroll down to Internet properties (tcp/ip), and press the Properties button.

On the "General" tab, pick Obtain IP address automatically, and obtain DNS server addresses automatically.  This way, these machines will work fine when taken home and connected to a network that's handing out addresses through DHCP.

But now, click the Alternate Configuration tab, and, on the alternate configuration page, pick User configured, and set these machines up EXACTLY as the desktops are set up, only each with their own IP address in the same range as the desktops, but not with the same exact IP address. Then "OK" your way out.

Now what happens with the laptops is that when they're connected to a network with DHCP, they get their addresses through DHCP.  When they're connected to a network with no DHCP (like your dealership), they TRY, but FAIL, to get an address via DHCP (since there's no DHCP server.)  When that happens, they then use the static ip address information on the "Alternate configuration" page.  If you set that up the same as the desktops, then if the desktops will work, so will these.

You need to set your Linksys Wireless G WRT54G2 in access point mode.The SonicWall TZ200 and the Linksys Wireless G WRT54G2  are both gateways/routers, and they conflict with each other over the ip adress. Thats why you get a web page time out.

Here is a how to:
To convert your WRT54Gs to a wireless access point:
1. Disconnect it from everything except one computer that is wired to it.
2. Give it a fixed IP address (one that is not the same as the wired router). So, find the wired router's IP address and add one. Example: if the wired router is, you are going to set your WRT54GL as
3. Disable the WRT54G2's DHCP server.
4. Save the settings.
5. Connect any (yes, any) LAN port (not WAN, LAN) on the wired router to any LAN port (not WAN, LAN) on the WRT54G2.
6. Is the WRT54G2's WAN or "Internet" port empty? It should be! If it isn't re-read step 5 9 more times.
7. Now, you have a LAN port on your wired router connected to another LAN port on the WRT54G2. If you don't, re-read step 5.
8. Set the wired router to be the DHCP server. Make sure that is not within the DHCP range -- you wouldn't want a conflict.
9. Done.

I hope this will solve your problem.

Thank you for the info.  Let me clarify a bit regarding the DHCP.
The SonicWall is controlling the DHCP but upon advice from SonicWall, I excluded the numbers that I had used for static ips from the DHCP range and any other devices that are not static receive their Ip automatically from the SonicWall.  
The linksys setup does not allow for a default gateway number.  
I set the Lan IP address and I get to put in the subnet of
I also disabled the DHCP server on the setup page of the Linksys.
I like the idea of the alternate configuration, I will try that this week.  Thanks.

If the Sonicwall is handing out DHCP addresses, then (under my first proposed solution), you wouldn't need to give the Linksys a gateway address...it'll just get it from the SonicWall.

Furyan's suggestion to use the WRT54G as an access point is also a worthwhile approach.

do you have the linksys connected to it's own interface on the sonicwall or do you have it connected to the network switch that connects to the sonicwall LAN (x0) interface?  if on the switch, then the access point should be bridging the wireless to the wired network and handing out IPs for the LAN network.

Sorry everybody but it turned out to be an issue with the website itself. All is well. Thanks for your interest and my apologies for not getting to back to you soon.
