HELP, why do I get 1.5-2M DL speeds on Vodafone Red Network (New Lynn) using G604T


Ive applied the latest firmware and ensured the settings are all correct.


using speedtest.net I seem to average anywhere between 1.5 - 2M download speeds. If im lucky and its around midnight
that can increase up to a whopping 3 - 4M ! yay. yeh right.


The exchange is about 1km max away, however my line is underground until the street where I suspect its overhead from there.




Thoughts anyone?


Cheers
Goose

Can you tell us more about your house wiring, ie how many phone points, with how many actually got phones, faxs, Sky boxs fitted. Is there a central alarm in circuit.

What does the line stat say, ie attenuation, Noise Margin(S/N) sync rate etc.

sure, have a wired splitter at the POP. Sky box not connected to the phone line. Only have two phones connected to the line and it doesnt make any noticeable difference unplugging these. There is a alarm in the circuit, however as stated the splitter is at the POP and the Chorus guy orginally ran a new run to where my router is plugged in.

SNR down= 9 UP=-10 dB
Line ATT down=27 UP= 13 dB
Data Rate down=11682 UP=165 kbps

Gooseybhai:Data Rate down=11682 UP=165 kbps

There's your problem, your upstream is only 165. This should be much higher if on the read network - as they are all FS/FS. This low upstream limits your connection to about 3.5Mbps max.

I suspect your router is syncing on RE-ADSL. Try locking router to DSL1 only, or ADSL2+ only and see if you can sort your upstream speed.




Chorus has spent $1.4 billion on making their xDSL broadband network faster and even more now as they are upgrading their rural Conklins. If your still stuck on ADSL or VDSL, why not spend $195 on a master filter install to make sure you are getting the most out of your connection?

Ok, so your sync rate is correct for your attenuation so I dont think there is a DSL issue and with a professionally installed filter all should be good on that front, but it may pay to check the stats page for any ATM dropped frames, if there are lots of errors and corrected frames then you may have a problem.

Obviously with a 160kb/s uplink dont expect TCP throughput to exceed 4-5Mb/s.

What are you using to check your throughput, if you go to www.speedtest.net and use the Auckland server what do you get.

Thanks for helping me Cyril

using ADSL2+ Multimode as modulation type, is this correct?

Ok, well until you change your plan to Fs/Fs I dont think you can expect much diff although I would still expect better than 2.15Mb/s D/L with a sync rate of 11Mb/s. I suggest you take it up with Voda, and change to a Fs/Fs plan.

Multi mode will let it use the best it can sync to, which appears to be 2+ so all is good. As I say the modem is syncing at 11Mb/s to the link to the DSLAM is not an issue, however the 160kb/s uplink is an issue and potentially some other limiting factor above that, but I dont think its a problem with your physical layer DSL link.

Firstly change to a Fs/Fs connection, there will always be limitations while on a limited US, although more like 4.5Mb/s not 2.

Other than that talk to voda see where you get to, but I dont think its and issue with your line or connection to the DSLAM.

If on the Red Network, connection will be FS/FS. So either there is a fault, you are not on Red Network, or the router is syncing funny.
Lock router into DSL1 only (ADSL muilti mode on d-link "advanced/ADSL" page). Post back sync speeds.

I discovered if you threw your G604T out the window and buy a new router you will love yourself.

I did that with my G604T and got one of those Thompson routers.

And to my surprise my sync speed suddenly changed for 5mbit to 14mbit :p

So that's how crappy that G604T's are. I even had the ADSL2 firmware on it which did absolutely nothing.
