Adsl vs Adsl 2

[feral]

My Adsl 2 is dropping out.:twisted:

The first plan I was on for Adsl was 256, then went to 512. This service was very good and reliable. It hardly ever dropped out.

With the new plans I found I was able to go to Adsl 2 with a 25% drop in downloaded megabytes.

My problem is that it drops out heaps....every night at least 10 times over 6 hours.

I have a Netcomm NB5 Plus 4W modem router. I have upgraded firmware for it and have the latest drivers for the wireless laptop.

Any ideas before I tackle my ISP? I'm also not that much of a computer geek so treat me nicely :cool:

Which ISP is it ?

I would first try locking the modem to G.DMT (This is ADSL1) and see if your drop outs stop, that'll tell you if it's the DSL2+ thats the problem.

If you've got an the version of modem I think you do you need to go to 192.168.0.1 in ie
it's usually admin for the username and admin for the password
-click advanced settings in the lower left corner
-click setup at the top
-click modem on the side under wan setup
-change it from MMODE to GDMT and save settings

Had much rain lately - mine always drops out when it rains.

Adsl2 is pretty sensitive to interference. If you haven't already, it's worthwhile disconnecting as much phone equipment as possible. I've removed all but one handset - much easier when it's all cordless phones. I also disconnected all of the extra phone sockets, so that there is only one phone socket in the house, and the modem, splitter and phone all connect to it.

Also try and identify which is the socket that connects directly to the street. The idea is to have as little distance from the street connection, and as few cable joins as possible.

This may or may not improve your dropout problem, but it's probably the first thing you'll be asked to do when you make the call.

The other questions are usually about things like interference from cordless phone handsets, or microwaves if you are running wireless - don't put them next to each other.

Another possibility is to swap your line filter for another, can sometimes cause a problem.

Oh, and do you have any fancy accessories on your line, faxstream, pair gain line, etc. that might interfere.

Or just call them, they'll reboot the modem at the telephone exchange, tell you that they've upgraded the firmware and that all your problems are fixed.

Then when you call back because the problem hasn't been fixed they'll send a maintenance report to Telstra, but they'll probably stall you a few times before they actually send it off to Telstra.

Eventually you'll give up and either lodge a complaint with the Telecommunications Ombudsman, or you'll just switch to Internode.

My ADSL2+ also drops out when is rains or when the wind blows (above ground telephone lines).

I believe most of my drop outs are caused by Telstra's poor quality copper telephone lines and connections at junction boxes and exchanges.

You can get Telstra to come and check your lines but if they find nothing wrong (and do they ever find anything wrong) you will pay through the nose for it.

I recently upgraded from ADSL to ADSL2+ (best thing i ever did), previously i was getting constant dropouts to the point that as soon as i put any load on firefox it would disconnect and then continuously dropout/re connect every 5 to 10 mins. I hadnt changed any hardware in over a year so was perplexed as to what was causing it, i was about to get my isp to send someone out when just by chance i thought i would try updating my lan card drivers . This did the trick and now i sync at 4400 kbps and often get up to 5200kbps and i live approx. 3k's from my exchange.

Try changing ( Reducing ) the size of your MTU's though your Router menu. bigger size packets can cause data flow issues and drop outs.

Edit: I have the same Modem Router Netcomm NB5 + 4 port .

Our recent experience was for 8 months from September 08 we had constant ADSL drop out had 2 different techicians come to check house wiring as the iinet and telstra boys said tests from exchange to house showed no problems.

1st techician disconnected some wiring previous owner had done as home jobbie, moderate improvement in connection time but still had drop outs.

2nd techician installed a new line from front of house to computer point and installed a new outlet.

2nd techician who also worked full time for telstra got out his telstra detection equipment and traced a fault in line within 500 metres of house, he said the connection of the cabling uses some material is porous and water seeps in and corrodes the line causing the interference to enable drop out. he gave us some mumbo jumbo code phrase to give to iinet techical boys that indicated someone who knew what he was saying was true about the telstra line was corroded. Within week telstra were out repaired the corroded connection and since then we havent had any drop outs.

Lyndon,

I'm a consultant - and have always found the NB5 series of modems to be very sensitive to line noise. Interestingly enough, the NB6 single port modem I've found to be a rock solid device - even to the point where I've used them as replacement modems at businesses running them in a bridging scenario because they prove to be a very cheap and reliable alternative to paying 400-500 for the business grade ones provided by the ISP's.

I'd look at seeing if you can get your hands on an NB6 or NB6plus4W (4 port wireless version). I'd stay away from the Linksys WAG54G's as well as anything from D-Link if you have a noisy line.

Also if your filters are old, replace them. The white square ones that have an adsl and a phone port on them I find work best - the single port yum-cha ones provided with some modems just seem to die really easy.

Also, as mentioned on a previous post, try dropping the MTU back to 1492 and if still no good back to 1450. If it doesn't work at 1450, then MTU changes aint going to fix.

Last of all, try to work out which is your "first" point in the house. Most pre 90's houses get wired to the first point, then subsequent points from that port. I would then plug your modem into that port, then test without anything connected. If that proves well, then put one phone on with a filter, see how that goes... then two etc.. till you find if that is the cause of drop outs.

Let me know how you go.....

I changed to ADSL2 from a Wireless Broadband, and the ADSL is useless, takes about 5mins to upload a 520k picture file, and sometimes 5 mins to load a web page, other tmes its just so so, Telstra say that its working fine, and Wireless is always better and faster than a wired line! Any Thoughts?

Distance from the exchange impacts dramatically on ADSL2+ performance.

ADSL 2 or Adsl? Remembering your upload speed is always going to be a lot lower than your download speed.

1. If you know how to log into your router, then log in, go to your status/statistics page, and see if you can find the info on your DSL line. You should see an Down speed and an Up Speed. You may also see an Down noise margin and an Up noise margin. Post these results so we can look at what you have.

2. Really depends on your location and distance from the exchange - do you know roughly how far you are from your exchange location? You can see where your exchange is located by going to this link:-

Australian Exchange Guide v3.0 (http://whirlpool.net.au/wiki/'tag=Australian_Exchange_Guide)

On TPG's website, they have a very cool tool for their ADSL2+ enabled exchanges that they can determine what speeds you should roughly get from the exchange from your location.

TPG's DSLAM Coverage Maps (http://www.tpg.com.au/maps/?exch=RCMD)

To find out yours, have a look at the first link to determine your 4 letter exchange code, then replace the last four letters in the 2nd link and that should bring up the coverage area of your exchange. Note this will only work on most ADSL2+ Metro and Urban exchanges - wont work out in the bush where only Telstra's available.

Cheers,
-Adam.

I have not had a singlr drop out for 2 years.
My ISP is Internode and on ADSL2 with a Linksys wireless 4 port modem.

Not sure why its been so solid but touch wood, and all is looking good.

Try a different modem and see how that goes.

[feral]

I'm still trying to work all this out.

It looks like I am 3 - 4.5 k's away from the exchange so I imagine this drops the speeds down.

Here are some stats which you may find very interesting :spudnikwhat:

Modem StatusConnection Status Connected
Us Rate (Kbps) 773
Ds Rate (Kbps) 5313
US Margin 11
DS Margin 9
Trained Modulation ADSL_G.dmt.bis

Peak Cell Rate 1823 cells per sec

DSL Statistics

Near End F5 Loop Back Count 0




According to Adam's links the stats for my area upload was about 7000kbps.

There is a bit of difference.

The modem is connected on the 3rd or 4th line connection in the house. I imagine this would make a difference.
