Trebao bi malo vise napisati o tom problemu, tj na koji nacin si pokusao odraditi.
Kako ja vidim da ti IP adresa na mreznoj podesena na automatsku, pokusaj kartici dodjeliti adresu u rangu adrese na ruteru pa pokusaj da se spojis.

i ja imam isti problem, sa istom karticom, pa me zanima, jesi li uspeo da rijesis problem,

Resio sam,valjda je problem ovo sto je poter napisao bio.Uglavnom iskopah na nekom forumu ovo,pa sam to i uneo

Any DHCP server (in your case, your router) will always assign a static IP via the clients Media Access Control (MAC) address of your Network Interface Card (NIC).
The MAC address is usually showed as a 6-group of 2 digits hex number.
(eg. 01:2a:4b:6c:8d:0e). its also called a physical address by some OS’s.

if your WRT54GC router is set up as such
Gateway: 192.168.1.1
Subnet mask: 255.255.255.0
DHCP client list: 192.168.1.100 - 192.168.1.149
then you should be able to assign any IP address
from 192.168.1.2 - 192.168.1.99
and 192.168.1.150 - 192.168.1.253

Best check with your OS on how to verify your MAC address.
ipconfig /all via command prompt (MS Win)
ifconfig -a should do the trick for Linux boxes

Once you have set your static IP make sure you check-enable it in the WRT54GC checkbox.

There are some cases wherein the Router does ignore the set up static ip for the client and still gives it a dynamic IP.
the easiest workaround would be to assign a Static IP directly on the client. just make sure you have the default gateway correctly set up in the client.
The DHCP Server then should respect the direct Static IP request.

sad ne znam za koji ti ruter treba....

elem,da ne otvaram novu temu,povezah ruter sa pcijem,i modem za ruter,al nemam internet(ikom cable).klonirao sam adresu,jer mora da prijavi ikomu nova mac adresa.u ruter administraciji,je nasao modem i sve je podeeno automatski.Mogu i da pingujem,i lap top koji je preko wirelessa povezan sa ruterom ima net.Kontam da je nesto jednostavno u pitanju,al ja nemam pojma o tome
