Re: [SLUG] ADSL download speed/settings.
Silicon Chip mag this month suggests some ADSL routers are line-polarity sensitive. Try swapping around the incoming phone wires to see.

Gives you a pretty good idea of what sort of speeds you can expect in your area compared to what TPG customers are getting.

Hey mate, gonzo01 said: Line Attentuation Upstream 31.5 Line Attenuation Downstream 44.0 Are these figures reasonable? They may be reasonable for your distance from the exchange. Either way, 44 dB attenuation is not my idea of fun whether it’s able to be improved or not. Havent found anything usefull by Googling. I generally find the Whirlpool community to be most knowledgeable and helpful regarding ADSL. In particular this Whirlpool wiki page has some good links to get you educated: http://whirlpool.net.au/wiki/dslam_speeds Is there anything I can check/do to increase downstream speed? Apart from moving closer to the exchange? Standard rules apply: make sure the phone line going from the modem to the wall is as short as possible. If you have a fax machine, try temporarily disconnecting that. If you use an ADSL splitter, try bypassing that to see if it’s lowering your sync. Apart from that, there’s not a lot you can do. In extreme cases, the only solution is physically shortening the line — i.e. getting connected to a RIM. [0] Although that’s not suitable for all cases. [1][2] The other thing is to check for crackling on the phone line. If you don’t hear anything, call someone else and ask if they can hear anything (from experience, it can sometimes be heard only one way). Do you get dropouts at all? Most modems will show you how long the line has been connected for. If you leave your modem switched on for 24 hours, and you check the stats but the Internet has only been on for 30 minutes (and the “always on” setting is ticked), then you’re experiencing dropouts and that should definitely be followed up as a fault with your ISP. Cheers, Jeremy. -- [0] A RIM is basically a mini exchange that is usually closer to your house than the exchange. [1] If you are using an ISP that has connected you directly to their exchange, then moving to a RIM may NOT be what you want to do, as they would charge you more for the service by needing to go via Telstra Wholesale. [2] I work for an ISP that mainly services an area where only Telstra Wholesale ADSL is available, so moving to RIMs is not a problem for my customers. signature.asc Description: OpenPGP digital signature -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

Yes your lead from socket to Adam is a huge problem.

Depends how far you are from the exchange, as you've said. Hit the following web site http://www.adsl2exchanges.com.au and type your address into the Address lookup box on the left of the screen. I've found the estimates provided by this site to be reasonably accurate (plus or minus about 10%). If the suggested rate varies more than that from what you're seeing, you can try the following. 1) Remove ALL extension cables from your phone socket to your modem - get the line connection from your modem on as short a piece of cable as you can before it plugs into the actual modem. 2) Pay someone to re-terminate your phone socket from the boundary point - usually in the street - with new cable and socket. 3) Make sure your modem has the latest possible working firmware on it. 4) Call your ISP and see if they can help.
