andrew55 wroteGeorge, try a different modem and at times when you experience a speed drop check your SNR and rate.

@DjSam they must be giving you more than 8 Mbps. lucky!
Yes I am currently looking for a new modem to get. My SNR has been more than 26 dB even at the speed drops. I am running a tool to monitor it every second. It has to be the modem or a throttling from their part.
If it's throttling then everyone should experience that.

I don't get how Sodetel is the only ISP that offers 16 Mbps!
Can anyone state the best settings to use in modem configuration for higher performance/ping/speed (and a brief explanation if you feel extra nice D )?
QOS type
Encapsulation
Virtual Circuit
DSL modulation
MTU+ size
..
it turned out FUP got applied on my account hence the speed drops. A sodetel support guy just confirmed it.
@nefe_lpmk I set my MTU size to 1400 since it gets fragmented above that but you need to find out on your own from cmd. If you don't feel like wasting your time just set it at 1400 (anything below that you'd get a speed reduction). ADSL1 sometimes improves pings and SNR on some lines. You can try resyncing to see if it helps. I don't think tweaking the other options you mentioned will help a lot but i'm not too sure..

George, are you downloading a lot??
It depends how much "a lot" is... I used to download a lot more than now and never been FUPed. Seems they are more strict now.
Well for example, IDM is setting an FUP if subscribers download more than 3 GB per day on unlimited plans which are a lot more expensive!
If they set it when we download more than 3GB by night on limited plans it would be really strict.. anyways when I restart the modem the speed is back to normal for a couple of hours so their system is flawed :p
By day i am downloading at 800 KB/s and + , after 12 it drops to 100 KB/s .
unacceptable limitation

So i'm not the only one!

PS: it's the 4th night in a row.. yesterday I didn't download anything.. not even in the day and FUP still applied...

I was just downloading at 100KB/s so I rebooted the router and your trick worked, downloading at around 3.2Mbps (400KB/s) now. Thanks.

Don't talk about it too much :p They might notice alot of people doing that and fix it .
The speed is back to 4M and the torrents are incredibly slow at 100 Kb/s peak speed on 44$ plan
I hope this will work out starting August 1. Maybe now it's just a testing period.
Finally... 55 GB with no throttling at 12 AM
No throttling basically because the free internet starts at 1 am :P
Btw george, how come you got 55 gbytes? didn't they downgrade you to the 4mbps plan?
I got 55 gbytes, 6mbps. sent them an email to upgrade to 8 mbps waiting for their reply
they upgraded back to 8 after I called them... i advise you to call them I think It's better. They'll monitor your line again and upgrade back to 8 if your line supports it.
sent them email yesterday, if they do not do anything about it by tomorrow i will call them then
what is your SNR after upgrading back to 8mbps? and average speed on speedtest? and are you disconnecting aw no disconnections at all? :P
