My lan connection seems to start and stop....

[nippyjun]

Hello,

My problem is as follows:

I'm using a windows xp sp2 system. We have a T1 connection in our condo building. I have a dlink router.

The problem is that when i'm surfing the net all can be fine, then suddenly pages stop loading as if the network connecion has stopped. Then after 5-30 seconds (approximately) everything is fine again. This can happen a lot, or intermittently.

The network connection is still present during these times. I've tried to disable my software firewall and antivirus but these don't help.

My motherboard has 2 built in ethernet connections, but the problem happens on both.

I'm not sure how to trouble shoot this. Can there be a windows service that is causing this, or a hosts file issue? Any ideas?

start continuas pings (ping ipaddress -t) to different network devices. Start by pinging your router. Then the next hop (Condo's router) then the next (ISP's router) and then an inet host (google).

See where you start dropping pings, i.e. your router, condo router, isp, etc.

Thanks for your response. I'm not that familiar with pinging. Do i literally type this at the command prompt:

"ping myrouteripaddress -t"

What will it show and how do i stop it pinging?

Thanks.

Yep. Open the command prompt, and if your router's IP address is 192.168.1.100, type in:

ping 192.168.1.100 -t

It's show lines such as:

Reply from 192.168.1.100: bytes=32 time=1ms TTL=244

When that line changes to something indicating that it's unable to reach the host, that's when you're able to conclude that there is a problem between your computer and that device.

You can also ping by hostname, such as:

ping google.com -t

Pressing control+c in an active ping window will cause ping to end, and you'll be dropped back to the command prompt.

You can also open multiple command windows to ping multiple devices at the same time. Then just use the process of elimination to see where the fault is... if you are able to continue to ping your router, but not the condo's router, then the fault is somewhere between your router and the condo's router.

Thanks so much. The problem seems to be with the condo's router and the administrater said he's going to check into it.
