I will stump everyone with this one!!!

[Eltano1]

I have a LAN network with a DC (Server 2003 Standard), which also is my DHCP server with a range of IP, to limit how many IPs assign. My three PCs are running Win XP Pro, every one of them connects to each other and the net with no problem. But when I connect my D-Link DI-524 wireless router to the network, to get an IP for my Laptop (WinXP Home) and work in the net, BOOOMMM there goes my internet connection for the networked PCs. They can see each other on the network, but they can NOT go out to the net. No matter what do I do, even if I hardcoded the IP in each PC, and in my laptop, the PCs can not go out to the Net. Meanwhile the laptop is out happily surfing with no problems.
Can someone tell me what is going on?

best regards

I knew it. So far no replies.

disable DHCP on your wireless router.

you have two DHCP servers on your LAN, bad mojo.

 

[PC Freak]

I agree with spidey. you are saying you have 2 DHCP servers running. Disable the one on the D-Link.

Probably dishing up the wrong gateway on the second DHCP server. You don't explain how (without the router) you normally connect to the net (ICS on the 2003 box?), but you'll need to update that DHCP server (if the router is the sharing devices now) with the router address as the dished up gateway address

Thanks guys, here is my LAN configuration, which btw it is wired:

ISP===ROUTER===FIREWALL===DHCP SERVER===PCS

I have a PC on the other side of the house, which is wired connected as well:

PC===HUB (I need it to connect when troubleshooting and fixing my clients PCs) and from this HUB I connect my D-Link Wireless for my laptop.

I hope this would make it clear. I have a question, if I disable the DHCP in the wireless router how would I be able to connect to the net?

Best regards

does the wired part of the Wireless Router feed the network?

 

[PC Freak]

WHen you turn off dhcp on the wirelss it will act in bridge mode. your laptop will then get it IP from same dhcp svr as the other pc's.

 

[Eltano1]

Dennis, the asnswer is no, the wireless router only feeds my laptop. Thanks PC_Freak, will try that.

Thanks to everybody, I'm glad that I did not stump you guys.

I tried what PC suggested, but when I opened the interface I found that the router had already DHCP disable. What I also found was that this router has the same IP address as my firewall, so I changed it and here I'm surfing with my laptop, and nobody has complained yet. I will keep you guys posted.

Have a great weekend guys

Don't connect anything to the WAN port of the wifi router and disable DHCP. Assuming you have a 4 port wifi router, connect any of the ports 1-4 to the switch which is fed by the DC. It will then act as an AP bridge or simply a switch with wifi access. Also using static IP might be better.

Second that. I have 7 linksys wrt54g's hooked up that way on various networks. I turn off dhcp, hook only to the switched ports, and give them the "bacardi" address
(blah.blah.blah.151)
It happens to be out of the dhcp range of the server, and is easy for me to remember

^^ 151 is the exact same address that I give mine

Thanks guys, don't need to celebrate anymore for me. It was what I thought it was, having two devices with the same default IP address. Changed one of them (my wireless D-Link) and no more problems.

Best regards

glad you got it figured out.

Interesting.

I have the almost the same thing happeneing to me.
My setup is like this:



Cable Modem

--> Wired Router (10.0.0.1) DHCP ON

-- -- --> Wired PC's (10.0.0.100+)

-- -- --> Wireless Router (10.0.0.2) DHCP OFF

-- -- -- -- --> Wireless clients



Now what happens to me is that the wireless router stays up, but the wired router dies and has to be rebooted. Everything was working perfectly until the wireless router was added to the network.

Wired Router = DLink DI-704P
Wireless Router = DLink DI-524

Duncan, you can try a couple of things.

1) When you can get away with it, pull the wireless off the network. Attempt to duplicate a bunch of traffic and DHCP requests like normal. See if the problem was really the wireless, or just a bad coincidence. I had a 704P die on me earlier this year, so I am a bit suspicious.
2) Turn off the DHCP on the 704P, and turn it on on the wireless. Make sure the gateway is set to the wired router
3)If possible, use the wireless router as the router, and either set up the 704P as a dumb switch or replace it with a switch <best choice>. I understand that it may not be possible with the necessary location for the wireless, the current location of the broadband connection and modem, etc.

 

[Sparky Anderson]

I would have gotten rid of the 704P but i'm keeping it because it acts as a print server also.

I'll try your ideas when I get home tonight.

Thanks.
