Hey i got 54db for line attenuation .. how to improve the statistics? From the 1st page, if 50db~60db is poor and might experience connectivity issues .. please advise thank you

is this good???

Hi,

Need help if anyone can advice my line status and what need to be done. it seems Line Attenuation is high right?


Noise Margin - UPstream : 25
Noise Margin - Downstream :12

Attenuation - Upstream : 31
Attenuation - Downstream : 59

Data rate(Kbps) - Upstream : 512Kb

hi, anyone can help me clarify my doubt regarding the SNR margin for the Upstream for my modem

modem problem ?
can u try other modem to see if it modem problem or not?

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

Hi, can I know where to check the snr margin in my Riger DB102 modem? Thanks.

Guys,

Sometimes around 8pm to next morning, the line become unstable or very slow speed, during the day, the speed was around 1.3mbps to 1.6mbps.
However, during the night it can be 0.2mbps to 0.3mbps only.. BTW, im subscribing 1mb package.

If I subscribe to 4.0mbps package, will it increase the night time speed to at least 1.6mbps? or still become 0.2 to 0.3 mbps?

Anybody subscribing to 4.0mbps having slow speed to less then 1mbps?

mine is as below pls advice

noise margin upstream: 23 db
output power downstream: 0 db
attenuation upstream: 3 db

noise margin downstream: 33 db
output power upstream: 9 db
attenuation downstream: 0 db

how to set the modem type and modem port? ><

hello, i think i experience the same problem with you, i didnt notice the snr margin but my attainable download rate and actual download rate drop drastically, usually i get 2048kbps for dwnld and 512kbps for upld but sometimes dwnld rate drop to about 100-500kbps but upld rate stays the same.. sometimes i pick up the phone and then put it back and the speed comes back to normal...

haiz damn sienz... just moved to pj ss2. the line attenuation 60db + really cjb. at kota damansara my line attenuation up stream and downstream 0db.

i got a slow line speed...
below is mine config, any adv?

internet always disconnect/no respon, can't access router, need restart it

line problem or modem?

where should i see? the up streams or the down streams?

This is what i have. Any idea this data is good? Any sifus out there. Tks

I need some help here
All my readings are fine
I just realise my attenuation is sky high
Attennuation Down stream 124 Upstream 84.
Does tht means the socket have problem?
I tried remove to connect directly to the wall socket without a spliter and still show same readings.

how is my connection? Is it good, or bad?
