IP address reservation (x64 Windows 7)

[tekavec]

Hello to everyone!

I have a small problem which is, to put it simply, annoying. I use my home router with addres reservation on 3 machines, however, the x64 Windows 7 machine never seems to have the right IP address (IPv4). I assigned the IP address based on the physical address of the machine but Windows 7 never seem to get the right IP. I tried disabling IPv6 but it didn't help.

I have thought of setting my IP manually in Windows (I even tried it and it worked) but I do not want to have these settings since it is a labtop and I also use it for work and other networks...

If anybody know the solution to the problem please let me know.

Thank you in advance,

best regards.

Did you use the correct MAC address? Hope you realize, Windows 7 does not control the DHCP server so your problem lies there.

yes i used the correct MAC address since the router automatically finds all attached deviceshe and I also checed the MAC address via ipconfig.

Hello!
I have the same problem on Windows 7 x64.
I havent got a router, I have cable modem internet. (Motorola SurfBoard)
On xp everithings fine with the internet.
I have a Realtek RTL8169/8110 Family Gigabit Ethernet NIC with NDIS 6.20
If I repair the problem on the taskbar icon, then it maybe works. But if I turn of the computer for the night, and when I start it the next day the internet doesnt works. If I repair it maybe good, but when I restart only, it hasn't got problems.
Please help, because I don't want to repair every day! If there's a solution please tell!
Thanks!

tekavec - what kind of NIC is in your system?

I have a Realtek RTL8169/8110 Family Gigabit Ethernet NIC with NDIS 6.20

You should start a new thread because you dont have the exact same problem and it gets really confusing to reply to 2 ppl on one thread. teh OP has a router you dont. OP has 3 computers. See what I mean

Need to confirm that the DHCP service is in fact sending the correct IP address. You should probably use a packet sniffer for that just to be sure. If it is sending the correct information. There are only two things I can think of. Something you installed that inter-mangles with the network and DHCP client. Or the device driver for your NIC is corrupting the data. (Granted if the driver is corrupting data then packet sniffing would fail?)

I can assure you, Windows 7 is not actively disobeying the DHCP server on its own accord.

This is good news because you can rule out a hardware problem but a driver issue could still be to blame. Have you updated the driver?

I too am experiencing this SAME problem.
I also have Windows 7 x64, with a onboard Realtec GigE NIC, and Netgear WGT624v3 router.

I previously ran WindowsXP, and Reserved-IP addresses worked perfectly. So that means my router is fine.

Now since I installed Windows 7, I get a different IP everytime I power-up or wake-up my laptop!!!

So indeed, Windows 7 is DISOBEYING the DHCP server !!!

Any ideas??
