[Phenom II]

Is there a way to prevent my Siemens Gigaset SE572 Router re-syncing on its own ?

I switch it off and on and it will sync at a decent rate, then by the end of the day its dropped its download sync down from 6300kbps to 4700kbps which on a 6meg line is very noticable. If I cycle the power again, it will sync back up and give me the real download speed back.

Annoying as it takes a while for it to come back online.



It doesnt touch my upload speed, just the download speed.


ISP is UK Orange

Bump ?


What are the main factors that play in sync speed ?

Can I replace wiring / router to gain a better sync ?

Increase SNR margin and you will lose speed but gain stability.. (Often you can do this router side but your ISP can also do it for you if they are willing)

Switch from Fastpath to Interleaved, your ping will increase but you will gain stability.. (This needs to be done by ISP)

Factors in sync speed are DSLAM Chipset and Router Chipset, Line length, Line noise leading to Attentuation... higher attenuation is bad speedwise..

Crap internal wiring, improperly filtered extension sockets (and extension sockets in general), faulty microfilter all affect DSL sync speeds..

http://www.adslnatio...cts/xte2005.php Fitting one of these on your NTE5 master socket will replace your Microfilter, your extensions wire into it and are filtered so they dont affect your speed...

If your running the DSL off an extension socket that can also affect speed, you should run it from your master socket in the house.

To find out whether any equipment is interfering with your DSL..

http://www.hmmm.ip3....cket-nte5.shtml

Access the test socket, plug in a microfilter and connect your DSL modem to it and monitor your stability... if its better or your sync speed is higher - something is affecting your line internally.

I'm guessing DSL?

its quite common to see an initial higher speed and then it to drop down to a slower speed as the router sets to the correct speed over a few hours/days. It takes time for it to decide on the correct upload download speed.

However if you are used to or are expecting a better speed you could try replacing the dsl filter, get a dsl faceplace, change the cable from the router to the socket.

You could get one of these adsl filters that goes in behind the main faceplate, can't remember what they are called.

If you have an NTE5 socket you can remove the bottom section of the faceplate and plug the DSL router straight in to the service port only, you could also check if you have any extensions in the house and make sure they have filters in etc.

I'm sure most of this stuff you probably already know or have tried but its the kind of things I would look for, also you can if the router has the function look on the web interface to check the SNR or errors and if they are too high speak to your service provider who may be able to do a line check

Thanks, and yea I have already checked out most of those ideas -

There is no test socket, it is in the master socket, Ive removed the ringwire, there are no extensions



what I have found though is these logs continously appearing in the router



Ive done a google, but cant really find anything about them, anyone have any ideas of the problem here?

TR 69 is remote router management, where the ISP can deploy new settings or firmware to the router automatically..

[Phenom II]

I have remote management turned off - do I need this on to get firmware updates ?

And would I set it as any client, or... - it sounds a bit unsecure

Its different than that setting, thats just allowing remote management of the web inteface.

Its dictated by ISP in the firmware and usually not able to toggle from web interface, it allows them to remotely provision and upgrade their routers firmware and settings en mass whenever required.

http://en.wikipedia.org/wiki/TR-069

Should be safe unless someone at the ISP maliciously provisions a dirty config

[Phenom II]

lol Yea I figured this was not the right setting,

Ah well, so... This is a Siemens Gigaset SE572 Router



How much better speeds might I get if I bought a much better router, and some suggestions on which ones would be good ?

I am on ADSL2+ connection

[hjf288]

Depends on your attenuation and ISP DSLAM Chipset... i.e. if your ISP uses Broadcom and your modem has Conexant it wont run at max speed...

Can you post modem stats? I.e. Sync speed, Attenuation, Modulation, Errors, etc..

Netgear Dg834v4/GT, DGN2000 are good modems when paired with DGTeam firmware...

[hjf288]

Is that from test socket?

You should be able to get around 7200Kbps Max on a good quality line... Your noise margin is 9dB which will affect speeds but introduces stability..

A SNR/Noise margin of 6dB is usually sufficient and provides more speed.. but could introduce more instability.. Not sure whether you can change it on Gigaset modems.

I'd recommend trying the netgears i listed above since you can customise downstream noise margin, they are very stable also.

They may not match Oranges DSLAM chipset though so im unsure how speed will be affected but you could probably make it up with SNR Tweaking...

There is no test socket - that is plugged into the old master socket - the house is pretty old with original BT lines and old sockets installed

What is Oranges DSLAM chipset? I have just tried Telnetting into the router but can not get in


I have had around 7200kbps sync once - but it only lasted a couple hours - im lucky if I get 6000kbps now
