View Full Version : [ubuntu] Connection is slow, with packet loss to router

December 6th, 2010, 09:26 PM
In the past week or so, I'm experiencing connection problems-
The connection is there, but very slow, and usually i need to refresh pages once or twice before it fully loads. This symptoms is on a desktop connected directly to the router, and on two laptops.
Now, this happens on a windows-running laptop, so this might not be an ubuntu issue (unless there's a culprit process running on my machine or something).

Thing is, when i sometimes try to connect to/ping the router ( it times out / there's a packet loss.
I tried a factory reset, which seemed to help for a couple of hours.
Any suggestions?

Sounds like a router issue if its on all computers on the network. For starters try checking out bandwidth usage on the router or even try to make a some vlans to test each port usage.
If you plug directly into the modem do you still get the same network issues?

do you have bittorrent or another app that opens a large number of small connections? some routers can't deal with the shear number of partially opened connections, and start responding to everything as though it were a syn attack.

What tool should I use to check bandwidth usage on the router? the one I looked (bmon, tcpdump)- don't seem to tell that, but I might be missing something.
I'll read up on vlans.
The connection is good directly through the modem, although I tested it only for a couple of minutes.

That's possible.. I'll close that app and see if there's any improvement.

Thank you both.

Turns out it was due to ktorrent- I switched to Transmission on another port, and connection is great...
Thanks again.
