This is my SNR margin, U see my problem is very very funny and it happen normally in the morning most days. When i awake and try to suft net, i found my browsing speed is very slow so i check my router statistics, it show that my SNT margin for downstream is like 0.1-10 which is very low but funny part is i just need to pick up my house telephone, without making any calls just wait for few second the SNR margin back to normal again. This already happen two months ago yet TM still cant solve it... try resetting port, downgrade to 1MB due to my area cant support 4mb.. bla bla but the same.. The only way to resolve this problem every morning is to pick up my house phone and wait for short while and SNR margin back normal.. sometimes it hav to be done for few times only to get back stable..

What the hell is this funny thing? why each time need to pick up my house phone in order to gain back SNR margin? Any idea? since TMnut cant even solve it..Zzzz
