Hi guys..
I tried to apply 4MB package 2 times,first one is last year but they said not enough port..
Then applied again this year,last week..The TM staff said that my area couldnt support..
Here is my SNR and Attenuation :
Downstream :
SNR - 12.3
Att - 63.5
Upstream :
SNR - 18.0
Att : 31.5
Currently Im on 1Mb package..I want to know whether my house really couldnt support 4Mb..?

By looking at your reading, I believe that your Line Attenuation value is over the recommended level.
A quick guide for ADSL SNR & ATT thing...
SNR Margin (AKA Signal to Noise Margin or Signal to Noise Ratio)
The higher is better
6dB or below is bad and will experience no synch or intermittent synch problems
7dB-10dB is fair but does not leave much room for variances in conditions
11dB-20dB is good with no synch problems
20dB-28dB is excellent
29dB or above is outstanding
Line Attenuation
The lower is better
20dB and below is outstanding
20dB-30dB is excellent
30dB-40dB is very good
40dB-50dB is good
50dB-60dB is poor and may experience connectivity issues
60dB or above is bad and will experience connectivity issues
