How fast should ADSL2+ be? [Archive] - Australian LS1 and Holden Forums

Ok, I have been doing a few line speed tests over the last couple of days and the line speed is always between 2 and 2.5mbps.
I am on Telstra's Bigpond liberty ADSL2+ plan, I have a Thompsen TG782T modem and live about 2500m by foot from the exchange.
I have tried the speed tests with our home phone and associated filters all disconnect and there is no change to the speed.
Can anyone give me some guidance on how to work out what speed I should be able to get? No matter how much I read on the topic I cant figure out if my speed is normal or not.
The current speed has never been a problem but recently we have got a smart telly and I would like to be able to watch HD movies but cant (Bigpond movies doesn't download to the device anymore, its live streaming so a slow connection makes it impossible to watch HD movies)

Below is the DSL connection details from my modem but I have no idea how to decipher it.

Uptime: 4 days, 5:56:07

DSL Type: G.992.5 annex A

Bandwidth (Up/Down) [kbps/kbps]: 620 / 2,853

Data Transferred (Sent/Received) [MB/GB]: 368.91 / 1.56

Output Power (Up/Down) [dBm]: 12.0 / 18.5

Line Attenuation (Up/Down) [dB]: 36.5 / 46.0

SN Margin (Up/Down) [dB]: 5.5 / 5.0

Vendor ID (Local/Remote): TMMB / BDCM

Loss of Framing (Local/Remote): 3 / 0

Loss of Signal (Local/Remote): 13 / 0

Loss of Power (Local/Remote): 0 / 0

Loss of Link (Remote): 0

Error Seconds (Local/Remote): 59 / 0

FEC Errors (Up/Down): 162 / 4,567,046

CRC Errors (Up/Down): 162 / 27,958

HEC Errors (Up/Down): 24,396 / 23,796

Any help would be appreciated.

Depends is the answer...

number of subscribers in your area
quality of the copper in the ground
age of the exchange
time of day
carrier
weather etc

I've used www.speedtest.net and although I'm on ADSL2 I only get around 1.2Mb down and 600K up.
Our exchange is overloaded and there's not much else they can do except wait for NBN.

2.5k doesnt help but your SNR and attenuation is junk that's why your sync is slow. Could be bad copper somewhere down the line. I feel your pain as I'm in a similar boat and am only 800m from exchange. Bring on the NBN

Your down stream attenuation figures suggest that your theoretical attainable speed will be somewhere around 5800kbit\sec for ADSL1, and 6800kbit\sec for ADSL2. It suggests a line length of approximately 3330m. Forget ADSL2+ as you simply won't be able to achieve it with that line. This is only an approximation of course and your actual attainable rate is well below this.

Do you have anything else on the line like a back to base alarm? If not do the isolation test again using the first phone socket in the house and post the statistics up again.

Good ping. Slow transfers. Silly question but have you tried turning off your modem and turning it on again? Then speedtest again

At work we've got loads of Telstra ADSL connections scattered in regional locations all over the country and we've solved a lot of our problems by locking the modems to ADSL1 profiles but we're using Cisco 877s which are a bit more stable than typical home appliance modems. Otherwise, if NBN is available then go for it. Failing that, if there's Telstra or Optus cable in your street then get on that. Both are much more reliable and less susceptible to noise and prevaling weather conditions than ADSL.

I moved into a new area about 18months ago and signed up with iinet. I was told no ADSL2+ and they could hook me up on ADSL, which is more expensive than ADLS2+. Also if I pay an extra $10 a month I could get a boosted speed to up to 8mb. I struggled to sync at 5, and youtube meant everyone else in the house would be lagging. A while (read <1yr) later with no changes to any exchanges in the area etc, I swapped to SCTelco due to better pricing and downloads, and magically I got a ADSL2+ "DSL Speed (DS/US)11973/1019 Kbps" (current) connection speed.

Checking line details I'm 6860m from the exchange. So I'm happy with the newer provider.

How do you find your distance from the exchange Kev?

Ok, I have been doing a few line speed tests over the last couple of days and the line speed is always between 2 and 2.5mbps.

SNR is OK at 5.5/5 - mine is 5/4
Attenuation on your line is about avg too - mine is 33/43

I would do the basics - go around the house, check for other phone lines - if any, ensure they are filtered.

Personally, the Thompson series modems are shite - pretty much all modems under $150 are ordinary.

If you can find someone with a Fritzbox modem that will plug in and help, I believe this will help you get better speed.

Your non-remediable errors are very high (the CRC error) as are your Remediable errors (the FEC error) - I am guessing a bad line, or on a RIM. Distance is not really the issue - you are about the same distance as me and I am synching at 13721 kbit/s

You can get an estimation here http://www.adsl2exchanges.com.au/detailedsummarystart.php
Otherwise your ISP can give you a more accurate distance.

That's about what they all should be, minimum IMO

Sometimes I get a decent DL speed but crap UL speed and it can make it seem really slow (except when actually just DL)

No back to base alarm or anything else on the line but I plugged the modem into the only other point in our house and got these results.

That's a big improvement. In my house I moved the first connection into my linen closet to minimise noise. The original telstra connection was quite poor

The above are similar to the speeds I see at home on ADSL2+ but at work on the same ADSL2+ I see the below (proves that infrastructure means everything with ADSL)

The other thing to remember is once your speed drops below 8M on ADSL2+, its actually better to lock your modem into ADSL as ADSL2+ is more prone to interference due to radio bewteen 1100KHZ and 2200KHZ the copper acts as one big antenna, once you get more than 3km from the exchange ADSL2+ is useless unless you have minimal noise. ADSL uses below 1100KHZ and doubling the bandwidth to 2200 doubles your speed, depending on the DSLAM and the profile you may be able to get ADSL to around 11M

Also you will find your SNR will increase and your speed will increase to a point, the re-transmits are less. Basically, lower SNR, higher att. faster speed, less reliable connection. There are exceptions but they are few.

This is assuming your have moved your modem to the first point in the house and all other house points are hanging off the ADSL splitter.

20meg down on DSL is unheard of - you literally must have under a kay of good copper back to your exchange.

The above are similar to the speeds I see at home on ADSL2+ but at work on the same ADSL2+ I see the below (proves that infrastructure means everything with ADSL)Nah the infrastructure for any ADSL is pretty much the same (copper). Distance from the exchange (sub-exchange) means everything. The longer you are on copper, the more attenuation, the less signal you get, the slower the speed.

A vast improvement, looks like the lines in my house are the issue.Quite simple to fix with a central splitter. Basically with a central splitter all the internal phone wiring is bypassed, and a new dedicated wire just for your ADSL is used instead. I am almost exactly the same distance from exchange (downstream attenuation of 47.5 which = around 3.4km from exchange) and I get stable connections at around 7,400 kbps with a SNR of around 5.5 - 6, so your new results are right on the money.

Ok , spent the day playing with the wiring and have sorted the issue.
Not sure how the wiring is suppose to work but the way it is in my (very old) house is this.
1st point (ie. the line coming out of the ground under the house goes to this point) is in the main bedroom, the 2nd (and only other) point piggybacks of the first, while I was able to get 8.5 from that point it is too far from the lounge room to get a good wifi signal to the TV so I still couldn't get HD movies working on bigpond.
While I had the modem plugged into the 1st point I thought I'd try plugging the phone into the 2nd point in the lounge room, we only have one house phone so the house phone has always been connected via a filter in the bedroom. Anyways the phone wouldn't work when in the lounge room so I am starting to think something is fishy here.
Pull the 2nd point out of the wall had a look at the wiring, it looked ok and the colours were in the right spots according the schematics I could find on google.
Pull the 1st point and check the wiring noticed the wiring doesn't match the schematics I had, so I swapped the wires around on point 2 to match point one and I now have...
pin 2- green
pin 3- red
pin 4- black
pin 5- yellow

Not sure if this is right or not but I now have consistant 8.5mbps download with the modem in point 2, and I can get 9mbps if I disconnect the phone from point 1, I guess my filter needs replacing also. Watched a HD preview on bigpond and it was still a little jittery but once I disconnected the phone from point 1 it played perfect. Will have to test it out with a movie tonight after the kids go to bed.

Thanks everyone for the advice on this topic.

while I was able to get 8.5 from that point it is too far from the lounge room to get a good wifi signal to the TV so I still couldn't get HD movies working on bigpond.

That would be the modem - unless Telstra are providing 'N' series wireless now, it will be only a 'G'. If the funds can stretch, I would be looking to upgrade.

Is the TV wifi only? If it has an ethernet point, I'd run a line from the modem so it's hardwired.
I can understand WiFi for mobile devices, but a TV is hardly mobile.
The speed will always be around 100Mb for the cable connection, no interference from heating your dinner in the microwave etc.

Yeah, I probably should run a cable but I just havent got around to it, cable would have to cross a doorway so I'd have to get under the house to run it which I'm not really a fan of.

Just watched a HD version of "The last stand" (Not a great film by the way, ZL1 vs ZR1 car chase wasn't as good as I'd hoped it'd be) on Bigpond and it paused once for a second or so but was faultless for the rest of the movie so it does what I need it to now at least.

We're out in the middle of nowhere on a dead end road so I suspect the lines which run down our road are quite old...... :confused: We're also on Bigpond ADSL2+ and had the usual Thompson modem till it died in a storm, now how a basic Billion modem. I do a speedtest.net test every so often and have had ping results vary from 26ms to double that (typically mid 30s), download speeds from 1.55 to 4.13Mbps and upload usually 0.32. No significant differences overall between modems i.e. they each vary up and down.

I forgot to mention that's over a wi-fi connection too. One day I'll get my wife's laptop and try it wi-fi then hardwired. Also made negligible difference turning the modem off and back on as someone suggested.

Thanks Kev - almost exactly 3km according to that but given we live in a very lightly populated area I'm guessing the lines are old.........
