Slow Speed Faults: Difference between revisions

(Still Under Construction)

This page is to help customers diagnose a slow speed problem on their line.

Please see our [http://aa.net.uk/broadband-speed.html broadband speed code of practice]

=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==

Run some pings to our PPP endpoint - 81.187.81.187, run at least 100, and either look for loss in the final statistics, e.g.:

ping -c 100 81.187.81.187

PING81.187.81.187 (81.187.81.187) 56(84) bytes of data.

64 bytes from 81.187.81.187: icmp_seq=1 ttl=49 time=11.0 ms

...

64 bytes from 81.187.81.187: 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==

*'''TalkTalk Wholesale:-''' For TalkTalk Wholesale Customers, please run the speed tester at [http://internet-speedtest.net/ 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.

*'''BT Wholesale:-''' please run the speed tester at [https://speedtest.btwholesale.com speedtest.btwholesale.com]

Please also use our speedtester [https://speedtest.aa.net.uk speedtest.aa.net.uk] and let us know the results.

Please do run the various speed testers at different times of day, as this can help determine if there is congestion at peak times.

-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.
