I've been having this strange problem for a few weeks but am unable to explain it (to the help desk people at least) and was wondering if anyone could give me any help?
The problem is that when someone starts to download a torrent it becomes impossible to view websites or do anything else on the internet. I looked and the torrents weren't even downloading just had a lot of connections open so they aren't using all the bandwidth. Also made sure nothing was being uploaded to saturate the connection but even when someone is not using torrents but has opened a lot of connections this happens.
I have a WRT54GL router and at first I thought it was a problem with NAT and the tables in the router getting full but this doesn't seem to be the case as it happens even when directly connected to the cable modem.
I have performed heaps of tracert's and the problem comes from what looks like my cable modem?
1 1 ms 1 ms 1 ms 192.168.1.101
2 1028 ms 45 ms 17 ms 203-97-105-1.cable.telstraclear.net [203.97.105.1]
3 15 ms 10 ms 11 ms ge-9-0-947.u22.telstraclear.net [218.101.61.50]
4 19 ms 20 ms 24 ms ge-1-2-0-819.ie1.telstraclear.net [203.98.23.1]
5 128 ms 123 ms 95 ms ge-0-2-0-1.xcore1.acld.telstraclear.net [203.98.50.251]
.....
Every single time when I try to do a tracert while i am unable to do anything on the internet the 203-97-105-1.cable.telstraclear.net seems to have high latency and eventually it will come up with "No Route to Host - the my cable IP address" or something like this
Tracing route to www.blah.com [194.243.135.33]
over a maximum of 30 hops:
1 1 ms 1 ms 1 ms 192.168.1.101
2 <Cable modem address>.cable.telstraclear.net [<Cable modem address>] reports: Destination host unreachable.
Trace complete.
I am able to reproduce this on every computer in our flat also.
Is this a problem with my cable modem? Or is something happening that I don't know about?
Thanks for any help.
