Hi everyone.

I have a certain situation that really has been annoying me for the last two months and I can't seem to fix it. For the last two years I've been paying for a 4mbps line from Telkom. Since it was installed I have had no problems with it, having a constant 400kbps down speed. Recently it has been dropping to speeds under 200kbps during the day, and sometimes disconnecting. But what I have noticed is that after 12 at night, the speed shoots up and stays constant between 250 and 400 kbps. Also, I have switched all the cables and filters, changed the adsl mode in the routers setting to specifically adsl 2+ just to see if that might have been the problem, but still no luck. Also what I noticed is when the internet speed drops, or the internet diconnects and somebody makes a call from the landline, the internet works fine again for while(the times vary) but only at a speed under 200 kbps.

The router is a billion 400g and it has been working fine for the last couple of years.

I have tried factory resetting the router.

Any advice will be appreciated.

Try a different ISP during the slow times

How many devices do you have on your telephone line? ADSL modem, telephone, alarm, etc.?

Disconnect them all and plug you modem cable directly into the wall jack. If it works fine then it could be your POTS/ADSL filter or one of the devices is causing interference (especially cordless phones).

If not then it is a Telkom problem (Openserve or ISP). To determine which one...

Get a freebie account from another ISP - Mweb, Afrihost, Crystal Web, etc. and test with it during one of your bad times.

If the freebie tests 100% then your Openserve line is fine and the problem lies with Telkom Internet (your ISP).
 
I have the adsl modem, telephone, and an alarm system. It isn't the filter because I have bought a new one and it still gave the same result.
 
Also check on your modem for your line statistics and post them here.
 
The line statistics are:
Upstream: 512000
Downstream: 4096000
Snr margin upstream: 14 dB
Snr margin downstream: 29.5 dB
Line attenuation downstream: 52.5 dB
Line attenuation upstream: 29.5 dB

When you the line drops again you should check the stats again.

Who is your ISP, it does should like it could be shaping or throttling.

Okay so I made an freebie account from Mweb, it all connects fine and the internet works but it is really slow

Filters - checked
Modem - checked
ISP accounts - checked
Alarm - not checked.

Unless it is your alarm then it is Openserve related. This could be exchange congestion or a fault on you cable.

Phone 10210 and ask them to do a FULL line test, not the mickey mouse one that they do from the call centre as you suspect that there is a SHORT on your line.

Hahahaha will do thanks for the help
 
I had a issue a while back where the line would randomly drop and the sync and speed was all over the place, that is when I discovered the alarm company simply stripped open my phone line and connected the alarm like that, so every time the alarm company would "ping" my house the line would disconnect.

Your SNR is really good, the attenuation is bad but should be good enough for 4Mbps.

It could be that everything is 100% and you just need to buy a new modem, do you maybe have someone you can borrow a modem from to test.

I always ask about alarms!! Some very dodgy "techies" doing their installs.

Hi,
I had a similar problem on my line. Battled for months with Telkom until in the end they admitted it was a cable fault and they could not fix it.
I used this program: RouterStats http://www.vwlowen.co.uk/internet/files.htm to log and graph info from my Billion router. Pay attention to SNR. On my setup it used to drop low and then router would disconnect. If I picked up the handset of the phone the load on the line would discharge the capacitive buildup on the line and the connection would be fine for a while. The problem would also "dissapear" when the linesmen started testing the line with their handsets, thus claiming that the line was not faulty. The routerstats program helped me to prove to them that there was a real problem.
I got beter internet now since going on the uncapped LTE!!

True. First test is to disconnect all devices connected to the phone line and pug the router at the point where the line enters the building. This means that one must trace the incoming line to the wall socket and not simply assume that the socked you can see is the entry point.
