Connected but no internet

Question

I have an Inspiron 600m and after great difficulty I was able to get it connected to my wireless network and everything appears to be working fine (Good signal, no drops). Everything appears fine when ipconfig is checked. I can ping my router, my wireless access points, other computers on the network and even sites like yahoo.com but when I open my browsers (both IE and Firefox) the page cannot be displayed or times out. When I hard wire the laptop directly to router everything work perfectly. Any help would be appreciated.

jadedragonfly Are you running any firewall software?(Windows Security, Norton Internet Security, McAfee, Zone Alarm) You'll only need one enabled and properly configured.

I have waited to install firewall software until I could get it to work and have turned off windows firewall.

jadedragonfly Did you purchase your Inspiron directly from Dell? Unless otherwise requested, Dell ships Inspiron laptops running Windows XP and either Norton Internet Security, or McAfee from the factory. By default, both contain enabled software firewalls that can conflict with each other wreaking havoc on network configurations and internet connectivity. For troubleshooting purposes only, all software firewalls should be disabled. You can go back later and configure one firewall to work... Please, post a little more detail in replies?

I have recently reformatted and reinstalled the operating system on the laptop. Until now my laptop has always been hardwired. With the reinstallation I got a wireless access point and have being trying to get it working. At this point no firewall software is installed. I had hoped to install and setup the software but am hesitant now because if I can’t get this to work without a firewall, adding one will only complicate matters. In the meantime, I have Windows firewall enabled when I am not trying to get the wireless working. Thank you for your time.

Bit of a tough one here, but a few suggestions that may help... 1.  Please ensure you aren't connected via Wireless AND wired Lan at same time. 2.  Check your 'internet options' in IE (not knowing specifically about your network, you probably should have nothing check on LAN settings unless you know you are running through a proxy server or special configuration file...If you do...check those out as well.) 3.  Shell to a command prompt, issue the 'route print' command and check your routes. I doubt you have any persistent routes (especially after reformating and reinstalling) but take a look and see if you have (especially) multiple default gateways (normally, that is not a good sign!) 4.  It appears that only your browsers are having the issue (in which case I would look at #2) but can you validate that your other apps are working as well (e.g. EMail, IM, etc?)   LT

jadedragonfly If your router has a MAC address filtering configuration in it's utility, is your laptop's MAC address listed in the configuration for no internet access? Also, how does your wireless card list in Device Manager? Any yellow marks?     Message Edited by MRF4700 on 11-02-2005 06:08 AM
