Having a bit of a nightmare with O2 BB!


[link to this post]
 
First post on here so be gentle, I'll try my best to give people the information they need to try and figure out the problem.

I've been really annoyed with the speed im getting recently from O2, I cant even play a youtube video without having to load every 5 seconds!

Did a quick test to find this:

I remember running a test in December which I still have the screenshot for that shows I was getting just over 3mb d/l speeds, which although not great is much better than what I seem to be getting now. The last 4 months have been a constant 1mb.

I've called O2 numerous time and sent in a complaint to which they gave me some compensation (£14 thanks) but nothing has changed.

Here are some stats from the O2 Wireless box II

Uptime: 0 days, 1:21: 08
DSL Type: G.992.5 annex A
Maximum Bandwidth (Up/Down) [kbps/kbps]: 1,088 / 2,569
Bandwidth (Up/Down) [kbps/kbps]: 1,083 / 1,835
Data Transferred (Sent/Received) [kB/kB]: 0.00 / 0.00
Output Power (Up/Down) [dBm]: 12.0 / 16.0
Line Attenuation (Up/Down) [dB]: 31.0 / 54.0
SN Margin (Up/Down) [dB]: 6.5 / 7.5
Vendor ID (Local/Remote): TMMB / BDCM
Loss of Framing (Local/Remote): 0 / 0
Loss of Signal (Local/Remote): 0 / 0
Loss of Power (Local/Remote): 0 / 0
Loss of Link (Remote): 0
Error Seconds (Local/Remote): 0 / 0
FEC Errors (Up/Down): 4 / 3,958
CRC Errors (Up/Down): 4 / 3
HEC Errors (Up/Down): 61,995 / 2

I also live in a new build property so don't have a master socket, just an external NTE (I think its called).

Any help appreciated.

The sync speed is reasonable for te attenuation - could be a little higher but not too far out. It is your throughput that is very low.


Have you done a complete power cycle reboot? Maybe leaving the router powered off for 15 -20 minutes.

What about tests on the TBB speedtester - they will be recorded on your profile.

Go to http://www.dslreports.com/tweaks and run their test - what advice does it give?

Connected at 1.8Mbit at 54dB? Sounds low in the first instance.

Our old ADSL was about 55dB and we got over 3Mbit and our line is made of wet wool and held together by engineers spit by the looks of it.

Not sure what is up with the error counts listed. Seem rather strange.

Downstream sync speed of 1835 kbit is 2691 kbit slower or 41 percent of the average for connections with the same downstream attenuation of 54dB.

SNR Margin of 7.5 indicates you have noise problems on the line.

Output power of 16dBm indicates a line problem.

I suspect there may be some wiring problems between your external NTE and where the modem is plugged in.

Snip the bell wire in the external NTE, then reboot the router and see what they stats look like.

Im amazed how clever people are on this site being able to draw all of the above from the stats I posted. (bear in mind most of it is another language to me,lol)

TBB Speed test is here: http://www.thinkbroadband.com/speedtest/results/id/1...

Here are the results from dlsreports:

What number is the bell wire plugged into?

Here's the NTE -

Also, this is a pic of the closest socket to the NTE (just after the radiator), would that be classed as the first socket and so gett a better connection?

Currently have the router connected to one futher away in the living room.

Number three, the orange/white. I would also go around and remove it at each socket -- otherwise you are effectively leaving an aerial connected.

Quite likely. (But then who knows how long is a piece of string, without measuring it. wink )

Disconnected that orange wire in the external nte and it's gone from just over 1mb to 2mb, I'll post some more stats later. So you think it'd be beneficial to disconnect this also on the individual sockets?

Should I buy a master socket with an adsl faceplate and replace one of the extensions?

Yes, I would systematically go around to every extension socket and ensure that only the blue pair is connected. (Blue/white stripe to IDC2 and white/blue stripe to IDC5.)
Should I buy a master socket with an adsl faceplate and replace one of the extensions?
If you are going to do that, you should identify the location of the first socket after the XNTE and replace it with your own NTE5/A. Ideally you would remove the surge suppressor, capacitor and resistor from the NTE5/A before fitting it -- otherwise your pair will be doubly terminated. That said, I have seen situations where an OR engineer has left a circuit doubly terminated . . .

Once you have your NTE5/A fitted, then install a SSFP and take your telephony pair from its IDC2 & 5. If it is not convenient to plug your modem/router in at the location of your NTE5/A + SSFP, then you could run a data extension (using CAT5e cable) from the A & B IDCs of the SSFP.
