Where's the cabinet, in your front garden?

But the attenuation is quite high, even though the SNR's are excellent, which would indicate a further distance. My attenuation is 8.3dB down and 2.5dB up on a 350m distance from the cabinet. i had a 15dB SNR down at install (Nov 2013) which briefly improved to 17.3dB mid February, but has since dropped back to 13dB.

Nice lift overnight. SNR has increased nicely. Attainables are well up. Attenuation remains as is - I still believe there is a poor physical line to the cab from my house.

Got my profile changed today - extra 10 up and down.

30Mbit at an attenuation of 31.8? That seems very impressive.

with those stats

60/20mb should be possible
70/20mb if there is no line faults

100mb/20mb sync Nenagh - go vectoring

He might be right. Its worth a call to have them test it.

Cool, will call tomorrow so

Paying for up to 50 with Eircom. Must look into the other packages and see if I can get that wee bit extra.

Signed up for up to 70Mb with eircom. Distance by road from nearest cab is 450m although from what I've read on here attenuation seems very high for that distance.

Weird thing is i'v had these stats since early December when I got it installed. Looking at the Attainable Net Data Rate you'd think vectoring was enabled but they hardly have it enabled on our cabinet since December.

call to get yourself on a vectoring profile

with your stats you should be able to get 90mb/20mb

Network termination unit. The new phone point on the wall.

How long can it take for a profile change to take effect? I rang Eircom 3 hours ago about possibly being bumped up to 70mb and was informed my line could take it and it could be 15-20min before I would see a change and my modem would reset but there's been no change on my line at all since.

It can be hard enough to get an agent who knows what you're asking for so hoping I won't have to call them back again.

Will Eircom change the profile/bandwidth automatically or is it necessary to ring them?

Regards...jmcc

I got the change a 30min ago

I'm not getting the 70mb in speed or download tests though, speeds are the same as before.
