Cannot establish connection to router

[Daniel]

Hello,

I cannot establish a network connection with my new laptop Samsung X20
XVM 1730 V with Windows XP SP1. The laptop has Wireless LAN chip and an
UTP LAN card built in.
Yesterday I installed Win XP Pro (SP1). The drivers from Samsung are
installed, and both cards seem to work (device manager says both work
fine). I use a static IP (192.168.0.3) for WLAN and a static IP
(192.168.0.4) for LAN. For gateway and DNS I use my wireless router,
which is a Linksys WRT54GS with IP 192.168.0.1. There is also another
computer connected to the gateway with IP 192.168.0.2, and some other
WLAN devices, all work fine. I configured my WLAN settings, and the
WLAN connection gets established with a very good connection. I also
have connected the router with a UTP CAT-5 cable. Now I think,
everything should work... BUT:

If (on the laptop) I ping localhost or 127.0.0.1, everything works. But
there isn't a TCP/IP connection outside, i.e. if I ping my router or my
other computer which is connected to the router, every ping packet gets
lost. Even if I disconnect the LAN cable or switch the WLAN off, ping
doesn't work. And of course also the web browser doesn't work.

I cannot find the problem, and I don't know what to do. Has anybody a
tip how I can fix it?

Thanks in advance,
Daniel

first of all, you should not assign the same IP addresses to a multihomed computer. Leave one connection, can you ping from other computer (make sure no firewall block the ping)? or post the result of ipconfig /all.

I didn't assign the same IP address, I assigned 192.168.0.3 and
192.168.0.4.
But - I have solved the problem! The problem seemed to be my router,
which seemed to be overloaded or broken or something. Now I get a
connection, after I updated the router firmware.

Thanks for reading and thinking about my problem to all.
