• Just a question about reducing line attenuation
    5 replies, posted
I currently have a modem setup with a line attenuation of 32.5 dB upstream and 54.5 dB downstream. As a result, my internet speeds are extremely slow, reaching 2 mbps at the most. (My current plan is ADSL 2+, and the average download speed of ADSL 2+ in my area under the same provider is about 5-7 Mbps) It seems like the biggest cause of my line attenuation is because I have an extremely long telephone cable (Over 5 metres) connecting my router to the modem, as my nearest phone port is all the way in the kitchen, so my wire is against the wall and winding all the way around the walls to the kitchen. Unfortunately I don't really want to move my modem to the kitchen as I would prefer having direct sight of my modem in case anything happens to it, and because it seems a bit risky keeping a modem in a kitchen. What I'm wondering is, if I had an electrician run a cable under the house and create a new port, would that reduce my line attenuation? I have a few doubts, would the cable under the house be made of the same material as the phone line above my house? If so, would that remove the aim of reducing the length of phone cables I'm using? [img]http://i.imgur.com/EX71jp8.png[/img] I've made a quick diagram in MS paint showing my situation, the brown box being the phone port's location and the blue wire being the phone line. The red wire is where I am planning to put the new telephone port. Would moving the telephone port up to the study reduce the amount of line attenuation? If not, are there any other things that I can use to reduce my line attenuation? I've tried a new cable, and that didn't achieve much. Thanks for any help!
It's highly unlikely that any cabling in your house is making any difference unless the cable/ends are damaged. I run a 50m reel of telephone cable to my router/modem, makes no difference compared to a 1m cable connected directly to the master socket

Is the cable running past power cables or other high voltage equipment? Is the cable still intact?

If you have windows in the kitchen and study, try running the phone cable out the window from the kitchen and into your study and keep it out of that rats nest of wire.
As said by a few people above line attenuation is extremely unlikely to be affected by the cabling in your own home, I'm using a 20m cable around my living room and it's easily capable of holding 23mbps down with 15-20ms min ping and only 2-3ms of jitter. the problem is likely the external wiring. You say the average in your area is 5-7mbps, so assuming 5mbps is the lowest in your area and you are getting only 2mbps you should call your ISP and tell them you want the problem fixing as long as you're getting below their rated minimum they have no grounds to refuse
