dear all,
I would like to inform me why I don't have any DNS service through my laptop. It takes IP address, but when I hit URLs, there is no response. What should I look for? Below is the configuration of the router:

If you do an "ipconfig /all" on your laptop (assuming windows) what is the DNS server ?
On your router you have -
dns-server X.X.X.X X.X.X.X
under your DHCP config. What is this DNS server and can it resolve internet names ?
Jon

I manually configure the DNS service at my laptop to be router's (877w) DNS which is the X.X.X.X (dns-server 193.92.150.3 194.219.227.2)
My laptop and the router cannot resolve DNS names.
02-23-2010 01:53 PM
Where did you get these DNS server IP addresses from ?
Jon
02-24-2010 01:24 AM
I set them up manually at the running configuration. These DNSs are provided from my ISP.
02-24-2010 06:51 AM
Can you actually connect to a website by using it's IP address ?
Jon
02-24-2010 07:13 AM
I was told to try:
ip name-server x.x.x.x x.x.x.x (DNS server for your ISP)
I will let you know after configuring it.
