Recently my customer changed from iHug to Xtra and immediately encountered frustration with the new connection .. slow websites, websites not responding, VPN remote access to terminal server very slow etc etc.
A test to speedtest.net initially showed good results but repeating the test showed massive variations, eg downloads as good as 15Mbps but mostly poor and as low as 0.2Mbps.
Ping tests to trademe.co.nz showed little sign of any packet loss. Tracert testing also showed nothing abnormal.
Connect rate throughout all the testing (now spans about 2-3 weeks of frustration) seems to be steady and high:
Downstream Speed 17136 kbps
Upstream Speed 879 kbps
ADSL Modulation ADSL2+ (ADSL2+)
Signal to Noise Ratio Average/Minimum
Receive 17.0 dB/ NA
Receive 9.5 db
Transmit dB db
Network switch glitches have been excluded by various testing from different LAN clients, and total router throughput has been compared with testing throughput just after a speed test to exclude LAN congestion.
A throughput test to the youtube speed test video with quality set on 720p HD superimposed with the Windows network monitor shows an interesting cyclical pattern of throughput - ie bursts of data with intervening zero throughput - and masses of dropped packets.
After lots of ranting we finally got Chorus to attend the fault yesterday, but the tech had a glance at the connect rate and declared everything ok. We were desperately hoping for a port change.
This fault seems very similar to this earlier one... and I wonder if the customer has ended up with that other dodgy DSLAM port.
Hoping that someone can help with further diagnosis and maybe some help in moving the incredible Xtra Chorus wheels along.
