Problem with the browser or internet connection ??

[coldman]

Hello there, this problem is from long time, some time my connection works great sometimes i have a lot of troubles. After i connect to the internet the browser are working fine, after some minutes i can not open any page, with Mozilla the site just stays like it was and with explorer i get the error The page cannot be displayed. I really dont know where is the problem. I have an lap topo and it works great with the same cable, with the same connection, but i have those troubles with my pc.
I need help, please let me know if some one knows what the problem is
regards

This sounds more like internet connection, not browser based. Assuming that initially the site displays fine, then it cuts out.

Some things to try:
1) Visit OTHER sites, if they're up, then it's related to the initial site (likely, unless it's an "untrusted site").
2) Ping the site Windows: "ping www.google.com -n 3"; Linux: "ping www.google.com -c 3"
3) If no ping response, try this "ping 209.85.173.99" (one of Google's IPs). If it's good, then it would appear to be DNS issue, check your DNS settings and set them to "static" if you have the required DNS server IPs.
4) If no response from the IP ping, then this is likely an issue with your connection, try the typical cable checks, make sure the router is up, and even run the command "ipconfig /all" if the results are blank, try these two commands "ipconfig /release" and "ipconfig /renew"... in that order.

Hope that helps!

I pings every site and that means that i the problem is dns and i dont have static ip address.
What to do ?

Ah, so the pings on the IP work, but on the domain don't, right?

Assuming the problem machine is a Windows box, then this is likely related to incorrect DNS servers. Do you have the "actual" DNS information from your IP?

To see what you have been using for DNS servers, run "ipconfig /all" and write down the info inside of the "DNS Servers..." field.

If it's blank, then the issue could be several things, include an incorrect gateway.

If it's populated, take the DNS ips and compare them with "known working" DNS servers for your ISP. If they match, then the issue is something else (likely). If they're different, then you'll need to manually set your preferred DNS servers.

Let me know what you find out.
