Router SpeedStream 6520
Gateway 192.168.2.1
WPA-PSK ---TKIP
When using wireless, DHCP returns this IP
192.168.123.150 and a new gateway 192.168.123.254
It works fine if I change the settings for Static in the 192.168.2.???
I did many reset, reboot to factory settings but nothing works.
Could someone please help
Thank you

Log on to the router management page, then check for the DHCP setting and ensure you put in correct info. Looks like there is error on DHCP configuration.

If still not working, then you can try to configure the IP, netmask, gateway and DNS info manually on computer, see whether it works.

Hope helps..

If your gateway is 192.168.2.1 you must be pulling a ip from someone else's wireless router to get the x.x.123.x ip range.

Enable your ssid on the router so you know what network you are connecting to.

Are you ready for where Microsoft wants you to go today?

Sounds like there is another Router or Server running DHCP service.
Could that happen?

I have a distinct SSID
When I do View available Wireless Network, I only see my SSID
When I access the router through a browser
all the settings are fine and DHCP is enabled
the gateway is 192.168.2.1
I use a 13 character shared key. I just did a reboot to factory settings and the same thing is happening.
Can another router without SSID take over my DHCP? Is that possible?

Thanks for all the help

Yes !!
If you get connexted to your wireless router, you can also get an ip-address from another DHCP-Server in your network. This xould be another router with DHCP enabled.
Golden rule is:
ONLY ONE DHCP SERVER PER NETWORK.

If there are more than one DHCP Servers in one network, you'll never know which one will be seen first and gives you an ip-address.

Ok
I had to transfer all the user of this network to the T1 line which is much slower
All there is on this network is the SpeedStream 6520 with a wired connection to the computer I'm using right now.
On the laptop next to me I get the above mentioned bad IP.
There is nothing else on this network for now

Another router can't take over your dhcp unless you attached to that router. And then its not a takeover its just doing what it does. Which is why I mentioned the ssid so that you were on your network not someone elses.

Look at your tcp/ip properties on both the wired and wireless cards. I suspect you have a static ip entry and you need to remove it. Look at the alternate tab under advanced for the static ip on both interfaces.

Imagine the power if you knew how to internet search

The local connection (wired) is disabled
On the wireless interface, if I put my gateway
192.168.2.1 then the DHCP sends me IP 192.168.123.188
The ironic part of it is that it tells me that I am connected and my signal is excellent, but I cannot connect to the internet.

Do a ipconfig /all and see what is says is the the dhcp server , if this is not your router address then you know some other wireless router is handing those out . you could also try changing channels on your wap . You could also try downloading netstumbler and see if you can find out who is giving you addresses.

1) What is the scope for your DHCP server on your network?

2) Are you using a proxy server?

3) Off the DHCP of the router if you have another server giving out DHCP address.

4) Are the wired computers in the LAN having the gateway: 192.168.123.254?
If yes, you will be in a lot of trouble soon. cause they will soon start grabbing ip from the router

"On the wireless interface, if I put my gateway..."

Thynker what are you thinking here?

You don't PUT ANYTHING in if you are using dhcp.

Thynker you need to focus. You aren't following directions or answering the questions to eliminate issues so we can narrow it down to what your problem is.

1. set the wireless nic to "obtain an ip address automatically" and make sure there is nothing in advanced/ip settings tab.

2. did you setup your router?

answer back with the results of #1 and answer #2 please.
