Optimising your Broadband Connection

[IanMax]

Well, If the main line is the only one you have, and if the MAIN SOCKET into your house from outside has no other telephones on it you can get away with it, but if you have the 1 phone line and use this phoneline for voice calls also and have lets say 2 telephones plugged into it and a sky tv set top box plugged into the socket also then you would need a total of 4 filters, 1 for every device thats plugged into the phone socket to be safe. Many phones and extensions can cause slow internet connection speeds.


The best way would be to unplug everything as i said above and start from there to find out what causes your sync speed to drop to 3mbs.

Good luck.

Right, Ian.. Back from the office.

I've checked the setup. I have a junction box in the hallway from which one wire goes externally to my office and the other wire leads to a hallway socket. The hallway has 2 things connected. ie: 1 x telephone, 1x extension which leads to a skybox in lounge 1 and from skybox 1 there is an extension to the second lounge which has another skybox (multiroom). There is one filter.
The other wire leading to my office has connected to it via a filter my modem and a telephone.

I have just done a speedtest and exhibit the results at present as follows:



I've also checked the netgear router page and get the following:

Port Status TxPkts RxPkts Collisions Tx B/s Rx B/s Up Time
WAN PPPoA 10523 13637 0 66 414 10:14:52
LAN 10M/100M 15214 14850 0 433 112 10:15:47
WLAN 11M/54M 3666 0 0 40 0 10:15:37

ADSL Link Downstream Upstream
Connection Speed 4256 kbps 768 kbps
Line Attenuation 33.0 db 20.5 db
Noise Margin 15.6 db 14.0 db

The noise margin again seems high. I've checked all filters and they are fine.. or appear to be to my untrained eye anyway. I cant afford to unhook the phoneline going to the sky boxes as sky have already written to me once
I cant afford to connect this pc to my hallway telephone line since it will be difficult to work from a hallway! Any and all advice would be appreciated. On the router setup page it suggests i am getting 4256kbs downstream. i note this generally goes up and down though it has never in the past gone beyond 5mb.
Please help..

Having disconnected the phone from the filter in my office i note that the noise margin has actually dropped and the router page is saying i get 6.5mb! speedtests give varying results upward of 4mb.

System Up Time 10:50:36
Port Status TxPkts RxPkts Collisions Tx B/s Rx B/s Up Time
WAN PPPoA 1821 2216 0 776 5494 00:06:28
LAN 10M/100M 36978 30222 0 1100 205 10:50:34
WLAN 11M/54M 4087 0 0 42 0 10:50:24

ADSL Link Downstream Upstream
Connection Speed 6656 kbps 768 kbps
Line Attenuation 33.0 db 21.0 db
Noise Margin 6.9 db 13.0 db

The point i note is that the noise margin has significantly dropped by taking the phone in my office( not really required anyway) off the filter.

I'm much happier.. still dream of a faster connection though!

[ash91]

just a quick question guys:

which net adapter should i select for the optimiser? (i'm not very technically minded so can't decide!)

one says

1394 connection
connected
1394 adapter

the other says

Local area connection
connected
Realtek RTL8139/810x Family...

thanks

Hi again,

It seems that you have either a dodgy filter or a phone that causes problems.

6meg is not too bad but you should get about 8mbs.

The best thing to do i think is to unplug everything from the hallway ( as a test only not permanantly ) and only have the office line connected. If you have to plug in the office extension to the front socket of your BT socket then put a filter before the extension so extension is plugged into the filter, then put another filter at the office end where your router gets plugged into it. So you have the following. Master socket - ADSL Filter - Telephone Extension - ADSL Filter - Router cable. Whatever else you have plugged into this line remove for tests sake. If this makes even more of an improvement then only plug your hallway stuff in 1 at a time ( each time rebooting the router ) so you refresh the sync everytime you plug something back in. This way you should be able to see the MAX connection you can get with only the extension plugged in.


Another note would be if you have a wireless pc or laptop then plug the router into the main socket ( the one that enters the house ) with no filter and nothing else plugged into it just the router, connect wirelessly and get the stats wirelessly from the router and then you will see if your office extension is also causing problems.


I would definately say on a 33 attenuation you should get 8096kbps at which case if you do recieve that speed and you can change extensions etc... to plug in all your other phones / sky box's whist still connecting at 8096 then im sure you would get around 12mbs on adsl2+ but i think sky put you on adsl1 because of the noise casued by your phone or extensions.

I would get to grips with using something called mognuts utillity to get your detailed router stats ( this utillity logs errors and maximum sync speed )

The link is here Sky Netgear DG834GT utility version 0.4 , Just goto get detailed stats , and then click back on internet explorer and click on download and click open and select wordpad to view the file.


Hope i covered everything, let me know how fast it goes.

Hi ash91,

The

Local area connection
connected
Realtek RTL8139/810x Family

should be set.

As this is what is used to connect your pc to the router.

Thanks a lot man

[Mildoo]

Thanks
