I just realised most of the time calling tech support for network (espec streamyx) takes a very long time to solve the problem, and usually a frustrating process (not to mention causing "heart attacks" and "hypertension" and "strangling t*n*t's neck syndrome). Here are things which I found out and it helps greatly espec for the technical support side and yourself. At least it would speed up the the process on getting the appropriate actions done.

All this is taken from ZTE ADSL 831 Modem webpage. You can get the info via telnet too but i don't think everyone knows telnet .

1. If your case is having frequent disconnections, meaning suddenly got signal and no signal, first thing u should is check ur SNR ratings in ur DSL Param.



Check your local and remote SNR margin. the higher the better. the ratings below is for local SNR margin.

30 and above = Good, u shouldnt have disconnections problems.

15 - 30 = Maybe a few when peak time, probably your line needs to be changed

15 and below = Very FREQUENT disconnections. You should consult telekom to have your line checked, most cases are because the line are too old and once they are changed they're fine (the lines on the telephone poles). If you're using a lightning surge protector. REMOVE it. they are known to weaken the signal by around 50-70% in order to prevent the surge on devices.

I found this under WAN -> DSL -> DSL param

ADSL filters does not affect the signal quality for streamyx connections. they only filter out noise for your telephone. Using it or not shouldn't affect your data transfer at all.

As for attenuation, the lower the better. but i don't know the effects other than these yet anyway it shouldn't go above 40dB....most of the time attenuation increases with the decrease of SNR .

2. I have DSL signal but I can't login =(.

Check your ppp details.



Check your last fail cause.

Last Fail Cause: Indicates the action that ended the previous PPP session:

No Valid PADO Recvd: The unit initiated a PPoE handshake but did not receive a packet in reply from the ISP.

No Valid PADS Recvd: After the initial handshake, the unit did not receive a confirmation packet from the ISP.

Stopped by User: The user stopped the connection (for example, by changing the Configuration Manager settings for the PPP interface.)

No Activity: The PPP communication timed out, in accordance with the timeout period specified on the PPP Configuration page.

Auth Failure: The ISP could not authorize the connection based on the user name and/or password provided.

PADT recvd: The ISP issued a special packet type to terminate the PPP connection.

VC down: The Virtual Circuit between the unit and the ISP is down.

Internal failure: A system software failure occurred.

This is found under Routing -> PPP -> click the magnifying glass.

3. I can login but i can't surf!

Be sure to set your DNS servers...
202.188.0.132, 202.188.0.133, 202.188.1.5

4. I can't even login to my router page now, sometimes I can't even get ip address and i can't ping it.



Chances are you got into your router's blacklist......disable and clear it...remember to commit the changes. use another pc to login to it.

Try changing network cables too...for some reason it doesn't like CAT5 cables very much....i'm using CAT 5e cables now even though my CAT 5 cable is working fine with another network .

this is found in Services -> Firewall

For username and password for the modem...check under the pinned router transformation guide.

5. For more troubleshooting to find out which link is causing problem (gateway,dns server, international link)
Open cmd window, and type: (-t denotes infinite)

ping 219.93.218.177 -t
this would ping streamyx gateway infinitely,this is to test the link between u and TMNET gateway. if there's a lot of timeouts here, then u knw where the problem lies. typical ping here is around 50-80ms

if there's no problem, then do this
ping 202.188.0.133 -t
this would ping the DNS server infinitely, to test connection to DNS servers (typical ping is around 80-150ms)

ping google.com -t
this would ping google.com or any other sites, to test international links. for google.com its about 300-400ms.

basically the route path is
You -> Gateway (219.93.218.177) -> DNS server (202.188.0.133) -> Destination

Other DNS server ip
202.188.0.132
202.188.1.5 (my personal choice)

Latency needed to get data across the pacific is around 300ms.

6. Mis-capped case - how can i get back my "actual" bandwidth?

1. Save a screenshot of your router page with the upload and download bandwidth.
2. Make a call to streamyx hotline.
3. Tell them that you have been mis-capped.
4. Tell them that you are sure it has been mis-capped because :
i) you discovered about it when u accessed your router configuration page (IMPORTANT!). And make sure the screenshot includes the date on the taskbar so that you can ask for a rebate (you don't have this they say they cant check bla bla bla and say you cant rebate cuz in their system its correct since the day its been activated)
ii) you have a screenshot of it if they demand proof and u say u will send it thru email to them if necessary
iii) add frustration and unsatisfactory tone (VERY IMPORTANT TOO)
iv) be confident that you have been mis-capped. dont let the technician think ur a newbie
5. wait for 2-3 days, should be fixed by then. if not. continue to call, or just go to clickers and demand them to change on the same day or see their manager.

- I was a victim of mis-capped case too 2 years ago, got 512k instead of 1M. unfortunately i had to resort to step 5. Remember, you're the customer, dont need to be "understanding" to them. after all, this is their mistake, not yours.

*** tip by masamura! ***

By the way.. I'm here to let you guys know what to do if you are miscapped. Recently through my own experience of TMNet's crazy mood of purposely downgrading my 1Mbps link to 512Kbps, I've taken some steps that assured my restoration of speed. So here goes:

1) Make a report through 1300-88-9515
2) Call them once a day with the SAME report number that you initially got.
3) Call them till it's the 3rd *working* day.
4) Call them again on the 4th working day and tell them that you've just got "Suruhanjaya Komunikasi dan Multimedia Malaysia's" complain form and if the problem is not fixed by 7th day, you'll post it through POS-DAFTAR.
5) Continue to call them and also write e-mail to custcare@tm.net.my and tell them that you are going to complain to MCMC on the 7th day.
6) On the 7th day if they haven't fixed your problem(which I assure you, they will by now...) Go to http://www.mcmc.gov.my/consumer/complaint.asp and download the form, fill it in and send it to MCMC via POS-DAFTAR (for confirmation purpose).
7) MCMC will write a letter back to you within 3 working days. Scan this letter, attach it to custcare@tm.net.my and call 1300-88-9515 with the MCMC reference and let them know and tell them to update it to your report that you've complained to MCMC (it's part of MCMC's proceedure).

Finally..

Sit back. Continue to call them everyday.. be nice and talk to them nicely. Within 15 days, MCMC will call you and tell you that TMNet is going to send their technician the next working day + refund your lost of speed for that amount of time.. hehe! Personal experience!

Anyway, lesson to learn here is... Complaining at TMNet and LowYat do no good. If you *really* want to complain, go to MCMC!

>>> http://www.mcmc.gov.my <<<

p/s: As for me.. the technician came on a Sunday night and TMNet's senior engineer called me on the same night to confirm with me if my line have been upgraded to 1Mbps package. Took me about 1 month to get them to upgrade my line back + refund!

****************************
hope this helps......and please post here for extra suggestions here too.

p/s : i'm just a normal college student, i have no affliations with tmnet or whatso-ever.

WLFung : pretty much average...maybe u'll have some problems in surfing during peak times =.=.

strynch : at least ur downstream is good...upstream...oklar...not so bad

yeah ADSL filters/splitters affects a lot of they are spoilt, including disconnections when u pick up the phone or no dial tone to phone.

anyway, use internet explorer to login to the modem website. it doesn't load correctly in firefox most of the time.

siaush : i think urs quite ok leh..despite the high attenuation, ur SNR is still quite high. u shouldnt have many dc problems.

gold3knight : Try connecting direct without filter. if still no improvement, you have to wait until telekom come and change ur cables...

[W]HIT3_@NG3L : CRC error ar? CRC very hard to say wor...might be streamyx might be the router that ur data hopped on got errors or attenuation....

ampbuster and darkjedi : WAH........omg...so high..the stats same like my streamyx connection back in my hometown.....dc every few mins and then have to wait over 1 hour only can connect back ><. are u using any lightning surge protector?

timothyy: 2MB ADSL? *jaws dropped. ur SNR looks quite ok ak....make sure ur modem doesnt autostop when there's no data transmitting lor....

Morpheusyeng: if u want to access ur router via telnet, u have to go into the web interface first,make a username and password in authentication (i think). den run hyperterminal or cmd -> telnet ip address and enter ur username and password that u created. aztech telnet is a bit hard to use though, so be careful when u fiddle wif stuff via telnet. as of modem status, u check ur web interface -> under dsl, there should be a status about what ur modem is doing....

wk1168 and yyteik : ur SNR a bit low...maybe thats y always dc or got packet drop lor....is ur modem directly connected from the wall port or it got split at a filter /telephone splitter. if not, maybe ur line old oredi lor...check with ur frens nearby about the SNR margin and see....

amenlo9:a lot of thunderstorms around ur area? how about construction?

CRC errors generally are due to the data are changed/damaged/loss en route to ur. maybe due to attenuation or routers error. each data packet has a crc checksum for the router recalculate to see if the data packet received is 100% complete. if its not, it will be discarded. basically there's nothing much u can do about crc error,most of the time the cause is due to the fault of the transmission medium. in other words, ur telephone line (most probably).

interleaved - slower but less error
fast - fast but might have more error
these are posted somewhere in the forums but i cant recall....

i try to answer the rest of the questions later k...i doing assignment now......hard disk kena bad sector today just got replacement

SNR means the stability of ur connection, it does not have anything to do with ur connection speed. connection speed depends on latency and bandwidth.

davidsk2002 : should be quite stable..maybe 1 day 1-2 times dc......are u connecting directly to ur phone port?

amenlo9: hehe..thats the common cause .

BlitzAce : looks like telephone line problem lor...........the port quite far from ur area?

amenlo9 : there are many factors due to SNR drops, it doesn stay stable all the time, but it shouldnt have much drastic change, unless something drastic happens.

unstoppable: thats good

bluesky87: never liked hotmail....i think its the routing problem...since yahoo mail can open.

anyway guys, try this.
open ur cmd window, type

ping 219.93.218.177 -t
this would ping streamyx gateway infinitely, u can see whether the problem lies where. if there's a lot of timeouts here, then u knw where the problem lies. typical ping here is around 50-80ms

if there's no problem, then do this
ping 202.188.0.133 -t
this would ping the DNS server infinitely, to test connection to DNS servers

ping google.com -t
this would ping google.com, to test international links

basically the route path is
You -> Gateway (219.93.218.177) -> DNS server (202.188.0.133) -> Destination

Other DNS server ip
202.188.0.132
202.188.1.5 (my personal choice)

updated first page with this info.

for crc error, please do a google on it. i think u can find more accurate information abt it. (sorry im just not good at explaining )

bluesky87: routing means the way tmnet direct ur packets....
in simpler sense : the road u take when travelling, maybe the road u take got road block or got landslide, so got delay.

osxchd : u have a very big problem there...nothing wrong with tmnet...i think u should telekom to come have a look at ur wire...u staying at a very old housing estate?

SeeD: weird stuff happens sometimes....like my distribution box last time terbakar also i dunno...change it and i got 40++ SNR already.....got a shock when i open it that time .

artline : very obvious is miscapped case lor...and remember to print a screenshot of ur whole router page, and forward it to tmnet for rebate...dont be like me last time want to claim but forgot to print screen..no proof to show that they miscapped me .

osxchd: what exactly did the technician do?

those having frequent dc problems, please refer to my first post on the ping test..that way u'll knw where the fault lies....

edu: just wait for abt 5 mins.that should kill ur connection...

[W]ee[D]: miscapped case, go call telekom and tell them they miscapped ur line . REMEMBER TO TELL THEM THAT U KNOW ITS MISCAPPED FROM THE ROUTER CONFIGURATION PAGE. if not, they won't bother correcting it.

those having Aztech DSL600E, sorry i cant help u with it cuz i nvr use it before.if anyone use it before and know how to obtain parameters and information please post it together with pictures....if permitted i will merge it together with the first post.

osxchd : hehheeh good to hear...ur SNR went up by tonnes ^^. i share the same experience too, the technician came onli to find that my telephone cable was real BLACK and after i touch it half the cable crumbled to ashes ><.

stevenlys : 2-3 days dc once is quite random,but ur snr is still pretty low, and ur having a lot of crc error. try running the ping test so isolate the problem. CRC errors are quite remote and hard to isolate as they can happen anywhere along the data path.

Jehuty : it could be anything. its hard to pinpoint the problem exactly without doing trouble shooting. well most of the time, and sadly, the problem lies in faulty / old phone lines.

osxchd : CONGRATULATIONS !

3den: very common with aztech routers when there's too much load...always happens with my fren's router (argh he still refuses to lend me his to do "software dissecting", if he lends me i might be able to come out with a guide for u aztech router users out there.) the web commander version is the same for all aztech routers right?

phantom opera: despite ur high attenuation, ur SNR is ok, so i dont think u'll have any problem perhaps only 1 dc every 1-2 days

Anderson : check under the admin -> alarm. anything written there? is it congested? if it is, reduce firewall max tcp connections to abt 65.

dEviLs : i think ur gateway(192.168.1.1) is set as a relay dns server, thats why ur dns server is ur gateway. as long u set those 202.188.x.x ip's in ur gateway there shouldnt be any problem.

shadow: i think u need to off and on ur modem...the modem prolly over-worked...


p/s : i updated the first post with masamura's miscapped tip, i admit most of the tests and tips in the first post might be outdated, will update them when i have time (busy with compiler assg now). btw, tmnet's service is getting lousier and lousier from day to day, after i saw a slight glint of hope in their service a few months ago...



This post has been edited by SnoWFisH: Dec 14 2005, 01:43 PM

rewlie : what i meant is

your pc : DNS server : 192.168.1.1, gateway : 192.168.1.1
your gateway / router : DNS relay mode : on / true, dns servers : <dns server ip>

For those who experience downtime,
Just to save time when u call the streamyx help line. before u call please try connecting with ur windows xp dialer and note down the error number (eg. error 678). when u call the tech support, give them the error number. that would help speed things up a bit.

Those having slow connections....im not sure whether u can get this info from the operators but try asking how far is ur port from the exchange...if its 4km-5km that isnt much they can do cuz thats pretty much the limit of ADSL...

Theoritically, for your download speed of 2048 Kbps, your max fastest dl speed would be 256 kBps. Your downloaded speed is 215 kBps, so this is reasonable.

However, you mentioned you upgraded to 4MB, so your ds speed should be 4096 kbps, with a max dl 512 kBps. I don't think this is right. Even if its actual data stream, it shouldn't be that bad.

p/s: Been ages since I last look at this thread lol.
