Bandwidth (Up/Down) [kbps/kbps]: 1,282 / 11,684

Output Power (Up/Down) [dBm]: 12.0 / 19.0

Line Attenuation (Up/Down) [dB]: 20.0 / 36.0

Speed tests are not a good way to check your actual download speed. Try downloading from servers that you know are fast such as microsoft/apple and use multiple connections.

The thinkbroadband speedtest always reports low numbers for me too, whereas speedtest.net shows the true speeds I get.

For that downstream attenuation your sync speed is fine (I sync at 10500 with an attenuation of 39.5). If your line stays stable you could try tweaking your downstream S/N target to 3db using DMT (google it) which could get you another 500kbps.

Also make sure you're doing a speedtest when connected via a wired (not wireless) link as everyone and their dog now has a wireless network which slows them all down (unless you're on a very different channel).

More importantly, 802.11g wouldn't max out your connection.

Speedtest.net is garbage, as suggested you want to be looking for a decent sized file from a site that you know works well. Something like this.

my main PC is wired, and its the one i did the tests off of

this morning it sycned at 1,274 / 10,490
just downloaded the 100MB_nonzero.bin and its saying 100mb done in 4 minutes 3 secs - transfer rate 421kb/s

just tried it using my netgear DG384G, synced at 1095 / 10992
same file downloaded, saying 100mb done in 3 mins 36 - transfer rate 474kb/s

edit : with FDM download manager on IE7 i have been downloading some trailers at speeds between 800kb/s - 1200kb/s

philjohn · 23 Jul 2008 at 23:50

Downloading the 100MB nonzero I'm getting 1.0MB/s (megabytes), so there's definitely something screwy with your connection.

Whereabouts are you based? BE/02 have suffered from some contention issues down south (however I've just SSH'd into our office in london and on the BE line they have there I'm getting 1.66MB/s).

daveyp · 24 Jul 2008 at 00:13

you need to run tcp optimizer progy that will sort you out. You can find the proggy here http://www.speedguide.net/downloads.php

sunlitsix · 24 Jul 2008 at 01:04

ive tried tcp optimizer, its made no difference

philjohn · 24 Jul 2008 at 09:50

I think you should probably give o2 a call then and see if they can sort it out. They're tech support is typically pretty good.

Tested the 100MB .bin and is indeed fast. Maxed out at 2.21MB/sec.

its giving me the same speeds this morning so i will give them a call later on

sunlitsix · 30 Jul 2008 at 23:57

so i rang them up and he just told me to wait until the first 10 days had cleared due to line testing
my problem now is i cant play any online games, for example CSS gives me a connection error message after about 3 minutes ingame
i'll switch back to the DG834G and see if i get the same problems with that

oh and my stats today :

Bandwidth (Up/Down) [kbps/kbps]: 1,282 / 11,224
Data Transferred (Sent/Received) [kB/kB]: 0.00 / 0.00
Output Power (Up/Down) [dBm]: 12.0 / 19.0
Line Attenuation (Up/Down) [dB]: 20.5 / 37.0
SN Margin (Up/Down) [dB]: 6.5 / 3.5
Vendor ID (Local/Remote): TMMB / BDCM
FEC Errors (Up/Down): 408 / 670,224
CRC Errors (Up/Down): 408 / 199
HEC Errors (Up/Down): 22,047 / 159

theres a lot of errors there, could this be causing all my problems??

daveyp · 31 Jul 2008 at 13:36

have you tried this? http://www.dslzoneuk.net/socket.php?type=html

tolien · 31 Jul 2008 at 13:48

To know whether the error counters are relevant, you need the number of frames transferred too. The BeBox makes an awful job of counting errors though, so I wouldn't put too much importance on them.

sunlitsix · 31 Jul 2008 at 15:44

ah right ok, well ive just had a good 2-hours or so on xbox live with no disconnects or lag

daveyp said:

i will check the sockets now, i have tried plugging the o2 box straight into the main socket before though and it gave me the same results

tipsy · 31 Jul 2008 at 18:26

I've lost 1mb with the so dont worry :

down to 14mb now. I bought an xte2005 filtered faceplate & a shielded rj11 cable, dont know if ocuk sell these cables so I wont say where is came from. This has help my router stay stable so I'm happy here, google may help

sunlitsix · 6 Aug 2008 at 14:17

just a slight update the line has stayed synced at 1,287 / 11,216 for 3 days now, download speeds are still around the 200kb/s area unless a download manager is used

currently downloading the crysis demo using free download manager at 820kb/s

sunlitsix · 7 Aug 2008 at 13:04

Uptime: 0 days, 4:08:39
DSL Type: G.992.3 annex A
Bandwidth (Up/Down) [kbps/kbps]: 1,291 / 7,671
Output Power (Up/Down) [dBm]: 12.0 / 19.0
Line Attenuation (Up/Down) [dB]: 20.0 / 33.5
SN Margin (Up/Down) [dB]: 6.5 / 6.5

todays stats... is there any reason why the router now reports the DSL type as being G.992.3?

Phemo · 7 Aug 2008 at 22:57

G.992.3 is ADSL2 (ie. not 2+). Mine does that occasionally - just give it a reboot and it'll more than likely come up as G.992.5 again with a higher sync.
