Can't connect two machines simultaneously

I got a D-Link DI-524 WLAN router and two machines (one notebook running
Vista Enterprise English and one media center running Vista Home Premium
German).
Connect from a single machine to the WLAN works fine. Both at the same time
does not work.
If I ping the router (192.168.0.1) from both machines I can easily see that
one stops getting reply as soon as I connect the other and vice versa.
DHCP in the router's web config shows a valid lease and an IP address for
both machines. I also tried with and without security - makes no difference.

Any idea?

Kind regards,
Willi

Hi
When each one connects what is the IP that it is connected with?
Try a static IPs.
May be the DHCP provides only one IP.

Hi Jack,

Maybe I did not put my words exactly, but the DHCP seems to be fine.

The dynamic IP addresses the two machines get from the router's DHCP server
are 192.168.0.186 and 192.168.0.191, respectively. (BTW, they also have
different local IPv6 addresses).
I also tried to set the same IPs to static - makes no difference.

Kind regards,
Wiilli

Hi
D-Link (and other brands as well) have problem with some of their older
Router. Vista's TCP/IP stack was revamp and some Routers can not deal with
it. Email D-Link might be that your Router (the Dl-524 is an old device)
falls into this category.

Actually I bought the router just a week ago...
But thanks for your help, I will ask D-Link.

Hi
You got it a week ago, never the less, the 524 model is few years old pre
Vista time.
