Problem connecting to office network

[nichy]

Hello,

I have a desktop computer (Dell Optiplex GX520). It has intermittent connections to the company network. Means that when I open a page like google, etc etc from the browser, the connection does not last long. It breaks in between.

I tried pinging to other computers on the network, it can ping. And from other computers, I can ping my computer also.

These are the output for ipconfig and routing table :

Hi there,

If you are getting disconnected using the Internet connection, the issue might be due to low subscribed bandwidth or others in your network are heavily utilizing the bandwidth. Yes, you are able to ping another computer, but this is not related to the internet issue.

Are you part of the IT Department? If not, you might want to contact them and ask for assistance.

What could be the cause for the problem?

Hi nichy,

In addition to what 2xg suggested: Pinging IP address over the network would only check the LAN connectivity but not the connectivity to the internet.

Does the other systems on the network works fine on the internet. You should also try booting to safe mode with networking following the steps below:

Hope it helps.

Today I spent some time to monitor the network again. What I did was :

1) Use the existing LAN cable and connect to the same LAN port.
2) Open browsers (e.g Amazon.com & youtube.com) and left them on for the whole office day.

What I noticed was there was no intermittent connection (no breakage in internet connection).

So I believe what 2xg suggested was correct (the internet usage was high, while the bandwidth was low).

I even tried to access unix servers through putty. I could access without problems.

Affirmative, that's more likely the case.

Hi nichy,

Its great to hear it is working fine now. Heavy traffic on the network with low bandwidth causes the system to intermittently disconnect from the internet.

If you have any queries in future feel free to contact us.
