Question : Problem: Not able to ping the router and cannot connect to internet.

Hello,

I'm having a problem to access internet through my new wireless laptop. This is the hardware/software I currently have:
1- Desktop computer with LAN cable connected to the wireless router(DSL): No problem to access internet.
2- Old wireless laptop: Dell latitude D600, Windows XP Pro, WEP encrypt(64bits), static IP(192.168.1.34), Symantec Antivirus: No problem to access internet. Replay when pinging router.
3- NEW wireless laptop, HP Compaq nc6400, Windows XP Pro: HERE IS THE Problem, apparently same configuration as old laptop: WEP encrypt correctly defined, static IP (192.168.1.35), Symantec Antivirus: CANNOT ACCESS INTERNET and not able to ping router, gives time-out. However wireless network connection properties indicates status "Connected, signal Strength:excellent"

OTHER INFO:
In both laptops this configuration is defined:
- IEEE 802.1x authentication: Disabled
- Windows firewall = OFF
- Network authentication=Open, WEP with 64bits.

Summing up:
-Old laptop has internet access, can ping router.
-New laptop with same configuration, cannot access internet, unable to ping router (192.168.1.1). On trying to access for instance www.google.com it says "The page cannot be displayed"
-Internet LAN settings: Only Automatically detect settings checked and "never dial a connection checked".

I've spent many hours on trying to set up this but now I'm exhausted :S Any help is greatly appreaciated.

Thanks in advance for your help!!

Answer : Problem: Not able to ping the router and cannot connect to internet.

dtechnolgy is right. Try entering it first in TCP/IP properties for the Wifi adapter, DNS may not need to be edited if this works

Default gateway entry tells your IP to go to a certain address when you 'travel' from on address range to a different scope. In this case your router is the gateway for your address range denoted by the .1 at the end.

Your ISP will have assigned you either a fixed address or a dynamic which is a proper unique address, the 192.168 range is as you know the common scope used for internal networks. the background to this is a good read if you have sleeping disorders so won't bore you with this.

In order to access the Internet your PC needs to be able to find the router hence it's IP should be in the def gw field in the TCP/IP properties.

This is a good argument for the DHCP, unless you need to have the static IP set fo operational reasons you should think about it. Simply reserve the address in your DHCP scope and fix it to the MAC address of your wireless adapter (cmd => ipconfig /all , then note down the mac address). WHilst your at it sort out access control in the router and make sure the only devices that can connect are identified by their MAC. That way you add some other element of security above WEP (which I think you need as your old laptop may not be able to wifi to WPA)

Hope you are sorted now.
