2 lines in same house, 1 synchs 3x faster than the other?


[link to this post]
 
Hi all,

For the past couple of weeks i've been trying everything to get my "backup" line working as well as my primary line.

My main line synch's at about 2.5MB which i'm happy with (i'm very far from the exchange). However my backup line, never sems to get about 900k/s synch rate?

Things i've tried

Tried 3 different routers (BT 2700, Speedtouch 585v6 and a 546).
New RJ11 cable to master socket from router
Always plugged into master socket, not extension
Plugged into test socket
new ADSLNation microfilters in master socket as well as extensions
Changed extension sockets to be pre-filtered ones.

But nothing seems to make any difference? I've spoken to my ISP who says they can't find any real fault, but could arrange a BT BB Engineer to visit, but that will cost £144 or thereabouts.

Before I take the plunge, I'm just wondering if there's anything else I can possibly check at my end?

Many thanks

// Carl

Line stats from the two would be useful. Also does the "slow" line have any issues with voice - if so at your telephony provider to look at those first.

Looks like the bad line is noisy. It actually has better attenuation figures that the "good" line!

If there's audable noise on voice try to get BT to look at that.

I can't say i've noticed any noise on the line tbh when making voice calls, no crackle or anything, I guess I could raise a fault with BT but I can just see them coming out and charging me.

Which ISP?

I see you are on BT IPStream. What are results from BT Speedtester?

Bad line only been up 5 mins. Is that cuz you only just started using it, or has it suffered a bad sync event?

Good line = Zen,

Bad Line = Total Web Solutions, although was previously on Zen for the backup line but changed ISP, made no difference to synch speeds.

Bad line had been down as i'd put a new pre-filtered faceplate on there.

I'll download Java and try speedtester, don't have java installed.

My guess ? They have different E-side (green cabinet to exchange) routing. The only way you are going to get that checked/addressed, is to get an Openreach engineer out.

Does that matter? Unless they have vastly different attenuations, which they don't.
