I got this Thomson TG585 modem free from Telecom so I could get ADSL2+
According to Telecom's website I should be able to get ADSL2+
My street address is OK
My Plan is OK
The Thomson TG585 is ADSL2+ compatible.
When I tried to use it it was slower than Dial up!
They sent me a replacement after spending over an hour on the phone one night with support.
The replacement is also slower than Dial Up.
The Nokia M1122 that I have had for many years works beautifully still, but is not ADSL2+ compatible. It gives me 832 upstream and 7616kbits/s downstream. It has been up for the last 35 days without any problem.
But when I switch to the Thomson it is useless.
I do not use filters as I had a technician come to the house many years ago and install a separate ADSL line (split the line?)
Any suggestions?

Nobody can diagnose this for you from a distance I would suggest. If two fail, one would need to look at your line/port. Only Telecom can do this effectively. It looks like more than a helpdesk from whoknowswhere is called for.

What I would suggest you do is look in to the sync speed of the Thomson TG585 in the router status page, post back with what speeds it's sync'ing at.

Then, go to speedtest.net and post the results here
Then, go to pingtest.net and post the pingtest results here.

Lastly, see here: http://chillingsilence.wordpress.com/2009/11/23/the-importance-of-a-good-router/

Edit: BTW - Yes it's quite possible to diagnose remotely, just gotta ask the right questions and get the right answers ;)

Before I disconnect the Nokia M1122 and connect the Thomson TG585 I ran speedtest and pingtest with the Nokia.

Speedtest results: Ping 86ms. Download speed 6.48Mbps. Upload speed 0.63Mbps

Pingtest results: Packet loss 0% Ping 44ms Jitter 0% Grade A (Excellent)

Where do I find the Router Status Page in the Thomson TG585 interface?

Browse to the modem's ip address - probably 192.168.1.254

With the Thomson TG585 connected

Speedtest: Ping 63ms Download 0.93Mbps Upload 0.69 Mbps

Pingtest: Packet loss 0% Ping varied from 35 to 55ms

Jitter varied from 2ms to 44ms

Sometimes Grade A Sometimes Grade B

Yes I did that but could not find anything about Rouster status or sync speed

Unfortunately I don't have any of those handy to check with, I'm not a big fan of them.

Do you use the Wireless? I'm presuming not, since the Nokia isn't a wireless modem?

With that in mind, I would strongly suggest you try getting something such as the Linksys AM300 or the Draytek DV120, and seeing if either of those have better results?

Something else for you to try: See if you can force the TG585 in to ADSL1 mode? That said, the WebGUI on those is *the* worst I've ever seen for a router, so I wouldn't worry if you can't decipher how to.

Click on Broadband Connection and DSL connection shows sync speed. Mine shows 16,300 down so is adsl2+.

Here is some information from the Thomson Interface. It states it is synching? at 945/17.778 but speedtest.com tests show that it is not achieving those figures. Download speed is around 1.0Mbps compared to around 6.5Mbps with my old Nokia M1122 ADSL1 modem

Could you confirm that you are doing your speed tests while your PC/laptop is plugged into the router, rather than using wireless?

OK I have solved my problem. The problem is the CAT5 cable that I have running from the modem to my computer. It is a CAT5 cable which is quite old and is about 15m long. The strange thing is that it works OK with my old Nokia M1122 modem, but for some reason does not work properly with the Thomson TG585v7 modem with ADSL2+

Any reason why it was able to carry 7Mbps from the Nokia but only 1.0Mbps from the Thomson?

I connected my laptop to the Thomson with the CAT5e cable that came with the Thomson modem and it gets around 14Mbps. Thats twice as fast as the Nokia. So ADSL2+ is an improvement for me.

The wireless with the Thomson works well too delivering around 8Mbps

So, what cable should I buy to replace my old 15m long CAT5 cable? Does the length matter?

Do I need CAT5e? Does ADSL2+ require better cable?

Thanks

You are talking two different things here - the cable from the modem to your laptop is an ethernet connection which can run up to 100Mb/s (or even maybe 1000Mb/s) and you can go 100metres with it.
The cable from your modem to the phone jack on the wall is the ADSL2+ part and is simply an extension of the phone line back to the exchange - the longer it is the slower your line rate.

OK I accept what you say. But why do I get lousy results using the 15metre long CAT5 cable but I get great results using the half metre long CAT5e cable? And why is the 15metre long cable just fine with the Nokia but lousy with the Thomson?

Everything else is the same. Same cable from wallsocket to modem. Same laptop. The only difference is the ethernet cable.

Very strange - my guess is that the Nokia modem had 100Mb/s ports which only use two of the four pairs.
Maybe the Thomson uses 1000Mb/s ports which use all four pairs and one of pairs 3 or 4 is faulty.

Wild guess though -

I went down to Dicks Smiths today and purchased a new 10metre CAT6 ethernet cable, and lo and behold I now get around 14Mbps download. So it was definitely a faulty ethernet cable that was causing the poor performance.

Many thanks for all the advice.
