Interesting. That must be an ISP 40/10-style cap then as IP profiles for upload are always 20 mbps aren't they?

MHC seems to think its a possible provisioning problem at Openreach end, as the BT WBC IP Profile is 20 Mbps every time I check the BTw speedtest. As I'm on consumer BT Infinity and its been the same for 18 months, I'm not going to risk the help(less) desk. The business desk is a lot better. One good reason to migrate to a new ISP smile

Type a [ bracket then type PRE then ] bracket before the text, and [ then /PRE and ] after.

All here in the FAQ (link in the top bar):

Comparing these other data, I can spot two main differences from mine: the attenuation seems much higher, and the SNRM much lower.

Are mine upstream TX Power(dBm): -16.1 -31.2 -2.0 are ok?

Length of line directly affects attenuation. SNRmargin also varies based on how much interference/noise, and the longer a line the more noise it will pick up so more margin needed to hold the connection.

My SNR is very high at 13.6dB on downstream? Are these healthy or bad?

With an attainable of 100+ mbps you can't have much to worry about... tongue
