Unstable connection?


[link to this post]
 
Since a few weeks, I've been experiencing an unstable connection., or better said, small interruptions.

Symptoms are pages that don't load sometimes, but when refreshed load instantly, streaming video that freezes and buffers a lot, and many attempts before I'm able to connect to my office VPN (timeout or loss of connectivity according to the VPN client, Cisco AnyConnect).

When this started I was using a Belkin 7633 Modem router, with WiFi disabled and connected to a D-Link 825 for WiFi. The 825 started losing connectivity with internet every minute or so, so I swapped the 7633 with an old ST546v6. This fixed the lost connection every minute, but now I'm experiencing the symptoms noted above.

These are the 546 stats:

Uptime: 0 days, 0:47:34
Modulation: G.992.1 annex A
Bandwidth (Up/Down) [kbps/kbps]: 448 / 1,792
Data Transferred (Sent/Received) [KB/KB]: 0.00 / 0.00
Output Power (Up/Down) [dBm]: 12.0 / 16.5
Line Attenuation (Up/Down) [dB]: 31.5 / 63.5
SN Margin (Up/Down) [dB]: 6.0 / 7.0
Vendor ID (Local/Remote): TMMB / IFTN
Loss of Framing (Local/Remote): 0 / 0
Loss of Signal (Local/Remote): 1 / 0
Loss of Power (Local/Remote): 0 / 0
Loss of Link (Remote): 0
Error Seconds (Local/Remote): 4 / 0
FEC Errors (Up/Down): 0 / 5,189
CRC Errors (Up/Down): 0 / 51
HEC Errors (Up/Down): 0 / 41


I know my speed sucks, since I'm far from the exchange, but in the past I was able to sync at around 2200 with a very stable connection.

The site at http://adsl.tin2tin.net says I have these problems:
Down sync is low (63% of the theoretical maximum).
Only connecting on ADSL1 not ADSL2+.
The power values are out.
There have been 1 local loss of signal.
There are at least some error seconds (upstream*).
There are some FEC errors.


Any help would be appreciated.

G'Day alesarco,

Could you let me know how you're connecting the modem to the socket? ie: extension socket, test socket, filters/ssfp.

And with the power supply, is it in a plug by itself?

Kindest Regards,

Hi Azzaka, thanks for answering.

The modem is connected to an extension socket, which also connects the WiFi router, a printer and a laptop. Do you think this might be the problem? Should I try connecting to a wall socket by itself?

Please.

The extension cables/sockets can pickup noise and cause no end of trouble. Try thats and then let me know how it goes.

Also it could be that the wifi is causing some issue as well, hence I would suggest setting the channel to 3, 7, or 9.

Kindest Regards,

Well, plugging in the modem by itself seemed to have improved a bit, pages not loading are scarse, but I still have tons of FEC errors, and why I am connected to ADSL1 instead of ADSL2+ ?

ok something has changed on your line. See if the phone is running ok with no noises. If it has clickes etc on it then report a phone fault (not mentioning adsl at all !!) and see if this can be fixed
