Hi all,
I am a student and I live in a house with 3 of my friends in Bristol BS8 area. We have Virgin Media Broadband XL package and about 2-3 months ago we started to get very bad latency spikes and packet loss. Some of us play online games from time to time and these became literally unplayable. We reported this to Virgin and apparently 2 faults have been found in our area that can cause this. Both were fixed but we are still having the same problems.
The problem persists even if its one person using the Internet which is extremely weird considering we are on the best package Virgin has to offer.
Our usual set up is a NETGEAR WGR614 router. Some of us use wireless but my PC, for example, is connected to the router by an ethernet cable and I also have the same issues as people using WiFi, so it's not like its a wireless problem.
Our modem's trade name is Ambit and I tried rebooting everything / leaving it to cool down for a bit but that doesn't seem to help.
I also tried bypassing the router by testing the connection by connecting my PC directly to the modem - still the same performance.

Here is a quick ping statistic using Colasoft Ping Tool. This is me running it at night, when no-one else is using the Internet. So you can imagine what's it like at 6pm on Sunday:

Location:United Kingdom
Packets Sent:134
Packets Received:125
Packets Lost:9(6% loss)
Response time Minimum:12ms
Response time Maximum:106ms
Response time Average:32ms
I tried checking latency to the router when we are getting bad latency to outside network and it seems fine (while we are getting 200-500ms to virginmedia.com, ping to router seems to be 1-2ms).
netstat -s -p tcp command:
Segments Sent = 250846
Segments Retransmitted = 2114
After downloading a 700MB file from Virgin Media server:
Segments Sent = 485279
Segments Retransmitted = No change
At this point I am running out of ideas of what to do. Could someone recommend further diagnostics?
P.S. Saying all this, the download speed is very high. The above 700MB was downloaded at 2-2.5 MB/s. The problem is noticeable only in games and sometimes when browsing (web-sites will load very slow or not load at all and then suddenly start loading very quickly).
