I'm having serious issues with my internet connection, but before I phone Virgin, I wanted to make sure it's nothing my end causing the issues. First a bit on info, as my network is a little overcomplicated, due to living in a house with thick brick internal walls which cause all kinds of wireless issues. - I've got a Virgin 20Mb cable line coming in. - The default modem is connected to a Netgear WNR2000 wireless router at one end of the house. - I've got a second Netgear WNR2000 router located at the other end of the house, connected to the first with a ethernet cable. DNS is disabled on this router. - Both routers have different SSID's, and use different channells, 1 & 11. - There are 3 computers on the network. My server / media center connects to the second router using an ethernet cable, whilst the other two (my main computer & a laptop) connect wirelessly to whichever router is closest (wireless G only though). I've also tried a different configuration, where my virgin modem is attached on a long cable, so that only one router is used at the end of the house that has all the computers. The problems I'm having is that of poor internet on occasions, not all the time. Tonight for instance, I can't watch internet TV without it buffering every 30sec and missing 3/4 of the rugby match I'm trying to watch. SpeedTest.net suggests that my connection speed is decent, always coming back above 13Mb, and usually not far off the 20Mb I should be getting. However when I try a test on PingTest.net the Packet Loss test always fails (I've opened ports 5060 and 8080 on the routers), and my overall results come back as F = very poor. If I ping google.com from the command prompt, one fails almost always. I have the same problems from all three PC's, meaning poor wireless connection is not an issue, as the server / media center is connected using ethernet. Should I get straight on the phone with Virgin, or should I test my network even further first? Thanks in advance for any help. Edit. Here are copies of my results from Speedtest.net and Pingtest.net. Speed a little slow tonight. Retried the pingtest and got a D rating this time. Still not acceptable imo.
