Constant Port Errors/Disconnections on 4mbit ADSL

I am an Axxess client who recently shifted a 4mbit uncapped service for household use.

Since moving over, I have begun encountering massive numbers of disconnections identified as 'port errors' by phone technicians. My internet speeds are stable, but these disconnections take place extremely often and disrupt my experience.

These disconnections normally take place in the afternoon and evenings, with a modem restart fixing the problem until the next disconnect.

Telkom has dispatched technicians who weren't able to fix the issue.

The most recent technician stated that they could fix the issue by moving me from 'Eligwa 3 to MSAN' by asking at a nearby Telkom retail outlet (I live in the Vaal area). Can someone explain to me in layman's terms what this will do, is it likely to fix the issue and how long will it take?

I was told by a family friend that Telkom is doing maintenance or upgrade work on many exchanges in the Gauteng area and is causing higher speed internet users to have these issues, but lower speed users are fine. This seems consistent with the fact that I moved from a 1mbit MWEB service to 4mbit Axxess service and the issue appeared. Can anyone verify if this is true? May I receive a layman's explanation on how to fix this if it is true? I was told by my friend that if I wanted completely stable internet, I would have to downgrade my internet package's speed until I found a stable speed. Is this true?

Please and thank you.

No, it should say SNR/Attenuation and the measurement is in dB.

Yep,

Stats look good, but to improve them i would select ADSL in "DSL Mode" instead of ADSL2+, it should be in the configuration page and repost the new result.
 
I cannot find the DSL Mode setting you have mentioned. It doesn't appear to be under most of the Configuration menus. What would changing this setting do?

Also, if anyone could answer the questions in my original post, that'd also be great.
 
This is puzzling, I've also got good line stats BUT like you my line refuses to sync at the correct rates, 4096 down and 512 up. Lately my line has also been disconnecting randomly and has had times of no throughput with low attenuation and high SNR aswell. My line only syncs at 4090 down and 500 up, although this difference is insignificant many it points to a port issue! It used to sync at the correct rates and I never had a problem

Its not "wrong" sync speeds, its the ADSL type you select, if you select ADSL2+ it will show up as 500 (odd) instead of 512. But if you change the mode to ADSL (GDMT) you will see your stats increase and the sync speeds will become even.

I'll give this a try but my router has always been ADSL2+ IIRC

EDIT: one time it was also showing 4095 down and 511 up, also negligible but possibly pointing to a port issue?

those type of sync speeds I am seeing more often with people complaining about the same problem, I too have had to speak with Telkom a number of times about it.

the generic response was that it syncs at the highest attainable speed.

I played along with their theory, and asked them then to change the profile to a 2mbps connection, in other words if 4090 was the highest 2048 should not be a problem, but it sync'd at 2040...

changing the setting on the router to ADSL from ADSL2+ as suggested, did not make a difference in my cases. (maybe the port side setting needs to be changed to ADSL from ADSL2+ as well??)

I have seen this before many years ago and cannot remember what caused it. for some reason I keep thinking its a configuration mistake on what ever device makes the level 1 connection possible....


note: changing to g.dmt on the router side made a difference at one client, not the rest. thx for that.

I am seeing increasingly that some routers are not compatible with ADSL from Telkom, especially the HUAWEI equipment in the exchange.
Routers that give trouble on HUAWEI MSAMs include many Cisco/Linksys products.

for the time being... NETGEAR seems to be the best choice.
