Here is the situation :  I configured the router (dir-655) to use 192.168.1.xxx DHCP range of addresses. Everything is fine when I connect to the router with a wire. When I connect to the WPA secured wireless with the passphrase, I receive this ip address : 192.168.0.100 and I have no access to internet. I tried to open the router page in a browser (http://192.168.0.1) and I get to the login page of a Dlink DIR-601 for which my admin password does not work.

When I manually enter a static IP address for my wireless adapter, in the specified range (lets say 192.168.1.20), I can access the right network (mine) and all is fine.

How can I obtain a wrong IP address from what seems to be another router when I choose the wireless network and input my own passphrase??? I am mystified. I did try to change the SSID to be sure it was not duplicated and all of the other networks in my range are secured in some way.

Any clue?

Thanks
Richard

It almost sounds like your connecting to a different router wirelessly. Change the SSID to make sure it's your router your connecting too. Also make sure your not connecting to the guest Vlan.

I agree...it sounds like you are picking up on a neighbors wireless signal.  It is entirely possible that you both have default SSID setings and routers from the same company..DLink...for example.

I would also suggets you change your SSID to something more easily identified for your needs, but not so easy that a nosy neighbor could see its yours....not that anybody ever has nosy neighbors.... 8-)

I did change the SSID to something that is unique and still have the problem. It seems like a nonsense to me. All networks arount my building are secured so I should not be able to pick-up an address from them. I did a reset on the router and still the same. I wiped out all the info for my wireless adapter et refreshed the network list, chose mine, entered the password and still got this damn 192.168.0.100 which is wrong. Should I try to reinstall the firmware (seems like I have the most recent).

Thanks again for your help.

Router IP address is : 192.168.1.1
Subnet is : 255.255.255.0
Device name : archer
Local domain : blank
Enable DNS relay : checked

I just noticed in DHCP client list of my router that there is a DIR-601 router connected to my network. Obviously, I pick my ip address from that router instead of mine (which I still don't understand). I could probably ask the owner of that router to change its subnet. How can I find out where that router is located??? There is 85 appartments connected to that network!

If this is the info for your 655 then it appears you changed the IP address for the router.

Try logging into http://192.168.1.1

[Ronneske]

can you check the neighborhood ssid's and explicitly try to connect to yours.
Maybe in the first attempt Windows has registered the 'not yours' router as the preferred one.

Unless you fix this preference it will connect to the stranger first !

I have no problem connecting to MY router and access to the setup page (192.168.1.1) when I enter an IP address manually for my wireless adapter OR when I connect with a patch cord.

When I ask for an address through DHCP wirelessly, I get a wrong address (192.168.0.100) and the setup page I can reach (http://192.168.0.1) is a DIR-601 for which I don`t have the password. I tried many times to reconnect ti MY SSID and make sure it is unique and still the same. Now I have been able to determine that the wrong router is located on 5th or 6th floor of my building by physically unplug those floors from the network. Then, I get a good address. Does not explain WHY it is this router that provides me with the wrong address. I guess I will have to knock on all doors of those floor and ask to see their router setup...

How are you connected to the Internet (Cable/DSL)? 
Did your provider give you a modem/wireless router combo and this is what your wireless is picking up?

[begs]

Connected through a dedicated DSL with a fixed address on a cisco router on which I have my DLINK wireless router connected.

It is also interesting to know that it has been working flawlessly for two years before I began to have this problem, this week.

You're right about your neighbours device connected to your router and effectively running two dhcp servers which are giving out ip's. But if your network is secured how is this rogue hardware connecting to your router? Seems to me something in your wireless security isn't quit working right. Are you using WPA2?

[begs]

My security is WPA2. I managed to find the appartment where my problem was. His router is connected with a patch cord to the network. That is why his DHCP was available to the network. I did change his range of address from 192.168.0.1 to 192.168.100.1.

I still do not understand how it could interfere with my 192.168.1.1 range but it did solve my problem. If any of you guys (thanks for your help) think of a reason, let share it...

[duffman]

So it was all connected by wires? Why is your neighbours ethernet plugged into your router?

[begs]

I manage the building. It is a retirement residence and we provide internet in the appartments through a local lan. People are free to use their own devices on the lan and they often don't advise me before.
