I'm kind of fed up with having a relatively slow upload, so i've been looking around at various options (from satellite - high latency - yuck! to bonding multiple ADSL2+ lines together) and during my research i've stumbled across something odd.
I'm 0.3 miles from the exchange (the 'DSLAM', right..? and I get around 16.5Mbps down and 0.7Mbps up, on my ADSL2+ connection in speedtests. I was looking at the numbers on the router's stats page and figured i'd do some research into how good/bad they are. The modem (a Linksys WAG200G) reports:
DSL Status: Connected
DSL Modulation Mode: ADSL2+
DSL Path Mode: Interleaved
Downstream Rate: 21174 kbps
Upstream Rate: 912 kbps
Downstream Margin: 1 db
Upstream Margin: 8 db
Downstream Line Attenuation: 11 db
Upstream Line Attenuation: 3 db
Downstream Transmit Power: 9 db
Upstream Transmit Power: 16 db
As I understand it, the attenuation etc isnt bad, but the downstream margin of 1db is horrifically awful. I also notice that i'm in Interleaved mode, which I understand is to combat line noise.
I'm guessing that at 0.3 miles from the exchange, this is not normal, right? I have not yet done an isolation test (that'll be my next step), and am considering buying one of those faceplates with the separate ADSL port, which I understand are generally A Good Thing.
I guess for a standard ADSL2+ connection, I cant really complain about the rate im connected at - is the speedtest result i'm seeing consistent, though? I know you should expect to lose some bandwidth to overheads etc, just want to make sure im on the right track. I'm just wondering if the modem is having to do a lot of error correcting etc, slowing things down.
Apologies for all the noob questions
Any guidance would be greatly appreciated!
EDIT: I meant to say, i'm *pretty* sure I have a proper master socket in the house, and thats what the DSL modem is connected to. There is, however, an extension fitted to it (behind the socket) that was put in by our builder...
