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.
