Tests to run
Look at the CQM Graphs
The CQM Graphs can show visually the quality of your line and can help diagnose problems. the CQM Graphs page on the wiki has examples and help.
Ping
Rus some pings to our PPP endpoint - 81.187.81.187, run at least 100, and either send look for loss in the final statistics, eg:
ping -c 100 8.8.8.8 PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data. 64 bytes from 8.8.8.8: icmp_seq=1 ttl=49 time=11.0 ms ... 64 bytes from 8.8.8.8: icmp_seq=100 ttl=49 time=11.6 ms --- 81.187.81.187 ping statistics --- 100 packets transmitted, 100 received, 0% packet loss, time 99160ms rtt min/avg/max/mdev = 10.433/10.951/14.150/0.411 ms -This shows 100 pings sent with no loss, and an average time of 10.951 milliseconds - this is a good line.
Speed Testers
For TalkTalk Wholesale Customers, please run the speed tester at internet-speedtest.net (and submit your line number once complete). Please run this test at least 3 times, and preferably during various times of the day/evening Please enter your line number without any spaces! These results will then be available to AAISP staff as well as TalkTalk Wholesale staff.
For other Customers, please use our speedtester speedtest2.aa.net.uk and let us know the results.
-Bear in mind that online speed testers are not always 100% accurate, and should be used with a bit of caution. Also, run the speed tested on a wired connection rather than wifi, and without any other traffic happening on the line.
Traffic Capture
If your service is slow due to huge amounts of other traffic then do a Traffic Dump from the control pages to see what the traffic is.
