I face SNR problem before...
Solution: reconnect/change the connector which connect ur home line with the poll line (Main line)... DIY..

Another factor...
a phone line connected before the splitter...
all phone line must connect after the splitter..
Sign: when phone ring, or u call... ur internet line will DC...

Good or not ? Please advise. THankiu.

is mine okay?

Added on June 16, 2011, 8:03 amI faced frequent disconnections too...not sure is my modem problem or line problem.
I'm using Riger DB108-WL.

Please help

hi guys,

mine is 4mb bb deals.

DSL Status: Connected
DSL Modulation Mode: ADSL2+ AnnexM
DSL Path Mode: Fast
Downstream Rate: 4092 kbps
Upstream Rate: 511 kbps
Downstream Margin: 14 db
Upstream Margin: 30 db
Downstream Line Attenuation: 36 db
Upstream Line Attenuation: 9 db
Downstream Transmit Power: 15 db
Upstream Transmit Power: 19 db

i saw my Downstream Margin: 14 db is too low.
what happend if my Downstream Marginis lower than 12db?
will dc always?
isit higher cap will make Downstream Margin become lower?

u guys who keep posting snr margin and ask if it's low or high..
do u even read the first page ? it's clearly stated there...

if wan answer then answer this


don think u r too clever. not everybody can understanding clearly like u.
if u don like don reply, dont answer something not related. waste post.

read the manual or check the company that made that modem...........or try google

read the 1st post, seems cant understand to relate on my case.

Streamyx 1Mbps package.
facing slowness of internet connection for 4 days now.
can someone help me bout the SNR reading..

[attachmentid=2287286]

I have this figure and I read the first post.

SNR, Attenuation are good enough.

The Power (output/TX Power) goes until 18db

and currently (this 2 weeks) i am facing frequently call drops which might occurs every second in the time.

modem changing, tel line, splitter are changed again and again

phone calls made and technicians came as well

any suggestion?

previously my snr and attenuation is excellent, now it become bad..snr 18, attn 39.

any idea what happen? streamyx or my problem? thanks

Hi Guys, just realize I should have post my question here

According to the info in the 1st page, I think my signal reading is quite...err.....terrrible....

For SNR Margin, I constantly getting less than 7dB for downstream but my upstream is 18dB, which is borderline OK I think.

My signal attenuation is constantly more than 50dB for downstream and my upstream is about 20dB.

But even though my signal reading is quite bad from what is stated in the first page, I don't experience frequent disconnection. In fact, my connection is quite OK. There is one little issue though, the speed will not last long and will degrade over time.

I can get more than 100 kb/s download when it first started but eventually the speed will go down over some period of time and in the end, I'll be forced to restart my modem to get back the speed.
I wonder if this got something to do with my signal reading. I have been facing this kind of situation for so long that I think its normal for Streamyx. Now I'm not too sure.

Besides I'm not too sure whether my interpretation of the signal in my modem page is correct. I have attach the screen shot of my modem below. Hopefully the master here wil take a look at it and give me some advice. notworthy.gif

Btw, my Downstream Line Rate has dropped to around 1100kbps lately. When I first upgraded to 1mbps, I can easily get around 1200 ~ 1300 kbps. Sometimes I can get 1400kbps but lately its getting harder to pass 1100kbps. I'm stuck with 900kbps for a whole day when I connect during the weekends cry.gif

I'm not too sure whether I should complain to TM or not. My only concern is that they don't entertain me only.
Wonder what should I do sweat.gif

I am getting 2 different reading using 2 different modem.. Anyone know what's the cause behind it?

hi guys, not long ago my side here has been experiencing a lot of lightning strikes.

after one such event, i experienced severe service degradation on my internet service.. line attenuation used to be around the 15-20db mark but now it's at 122 Downstream, 149 Upstream! SNR still around the same.

can someone explain what's wrong? could my splitter be damaged?

hello, this is mine. pretty slow though, not as fast as before, 180KBps, now only 100KBps, max pun 120KBps saja.

how to get this page? im using riger modem

Hey your connection not stable? from the statistic you shown, it should be outstanding connection (SNR Margin) among so many ppl.

But the attenuation seem high. ><

But you might look it again after 30minutes see any change on those SNR Margin and Attenuation.

Added on October 2, 2011, 2:12 amHi,

First one [Aztech 605EU],
SNR Margin for download is bad. and it might experiencing frequent disconnect issue?
This is the key -> Trained Modulation ADSL_2plus_AnxM
You might change it to G.dmt and see how it reflect.
If still the same, please call TM and let them know your connection is in bad condition and need to check the physical connection from DSLAM toward your connection including DSLAM.


Second one [TP-Link],
SNR margin still in safe rate. but the attenuation is quite high.
Did you always get dc status?


*Note, for the best connection it should no exist the CRC error. Before this i did try to troubleshoot with TM about this issue and unable to fix permanently. That is my experience i not sure about others.

Added on October 2, 2011, 2:22 amPlease take out the splitter and make a direct connection from your phone line to the modem.
From there, you able to know is that splitter damaged?

---

Added on October 2, 2011, 2:27 amTry to change the mode to G.dmt instead of ADSL2.
See that this able to solve your problem or not.

Thanks war3boy for ur advice.

I tried to change the mode to G.Dmt but the signal reading doesn't improve.
Its OK bro, I've accepted my fate. As long as I'm staying in this house I will be forever 1 mbps

Oh, no Unify as my landlord does not permit TM technician to drill holes for the fiber optic cable

guys i want to ask, my stats are:

Downstream Upstream
Data rate(Kbps) 1536 512
Noise Margin 7 23
Output power(dBm) 53 31
Attenuation(dB) 122 185

its very bad rite? pj area anyone facing this?

Need help, I'm using innacomm. Connect wireless.

oard ID: 96333AW2G
Software Version: W3400V-4.02L.03-TM
Bootloader (CFE) Version: 1.0.37-5.12
Wireless Driver Version: 5.10.85.0.cpe4.402.0

This information reflects the current status of your DSL connection.

Line Rate - Upstream (Kbps): 512
Line Rate - Downstream (Kbps): 1536
SNR Margin - Upstream (0.1 dB): 240
SNR Margin - Downstream (0.1 dB): 303
Attenuation - Upstream (0.1 dB): 110
Attenuation - Downstream (0.1 dB): 205

The problem, very bad connection when playing online game. Keep lagging and disconnect.
Any solution to it? The stats of modem looks bad =.=''
