Except it doesn't. I have two HH2's and a BTHub4, all have been reset to factory prior to testing. The HH2's do not make a connection to broadband.
Yes I'm using a wired connection.
ADSL connection information from my BTHub4:
19:46:43, 21 Mar. ( 59.510000) DSL noise margin: 11.00 dB upstream, 9.00 dB downstream
19:46:43, 21 Mar. ( 59.420000) DSL line rate: 448 Kbps upstream, 352 Kbps downstream
I have alternated between the test socket and regular socket.
Just switched back to the regular socket:
20:55:11, 21 Mar. ( 4167.970000) DSL noise margin: 11.00 dB upstream, 8.20 dB downstream
20:55:11, 21 Mar. ( 4167.900000) DSL line rate: 448 Kbps upstream, 384 Kbps downstream
