    Not a whole lot to play with in the downstream SNR though. I don't think it would do 50Mbit but no harm seeing I suppose.
    Aye, that's what I was thinking too about my downstream SNR. I'm in two minds whether to ask Vodafone to rise my profile or leave it alone until vectoring comes in. I'd be concerned that moving up a profile could leave me with connection woes?

    I'd like higher upload speeds though. Damn greedy I am, considering I only had half a meg mere months ago! :)

    Not sure if they can do 40/15, that should be ok, but vectoring should be enabled soon. I'd leave it alone a while. Stability is more important than an extra few Mbits at these speeds.

    I was told I could get anywhere from 43Mb+ download and I should "expect" to be able to get 20mb upload. I think I'm around 400 metres from the cabinet. I don't have Fibre yet but those this sound right to anyone? Thanks.

    You'll get 50/20 at that distance at least. Maybe 70/20 with vectoring.

    I take back what I said about Eircom Broadband phone support techs, lad I spoke to was straight to the point and reprofiled my pre-vectoring profile.
    Now getting 30Mbps down and 4Mbps up, while I'm 1500m from the cab.

    After further testing, while my modem has sync'd at the higher speed the real world download/upload speeds (From HEAnet's FTP site) are still capped around that when it was syncing at 7/1Mbps.
    They prob don't have enough capacity in my cab, or the distance is still a factor? Confused anywho

    I'm about the same. Getting 50/20

    That's not how it works.

    You either have vdsl or you don't. The number of lines into a cab is of no concern as long as you are one of them.

    How are you testing the speed? Wired connection?

    @kerbdog - your current SNR at the higher profile speeds are barely adequate. You may be getting lots of packets being re-transmitted due to errors and thus you are not getting much improved throughput. At the distance you are from the cabinet you might be better on a lower speed profile until such time as vectoring is turned on. Your previous good SNR values were a reflection of the low profile you were on and not vectoring - certainly not three months ago.

    On phone with them now to try a lower profile. Gone to 25Mbps down and still kinda the same

    How will I know vectoring is enabled?

    Well I would imagine if vectoring is enabled your SNR values will increase in comparison to their value on the same profile. If eircom are switching profiles for you on request (you must have a good contact there!) then you will notice your SNR changing. It's difficult for you to know if vectoring is enabled unless you have a before and after comparison on a particular profile or if eircom tell you it's enabled!
    Three or four weeks ago I had a temporary improvement in SNR but it went back to its original value after a day or so. I reckon they were testing, but it has not been switched on since. I log in to the modem every day to check, but really I'm more than happy with my 66Mb down and 17Mb up!

    Cool, will keep an eye on it so. Now on the 25Mbps down and its the same. Looks like the errors keep racking up

    That's some increase - how do you get moved onto the 100Mb profile?

    Appreciate that - how or when does he get moved onto 100Mb? Will the operator do that automatically?

    Re-profiled, after evision discontinued, to 70/20. I'm 190m from the cabinet. SNR is poor but adequate and should improve with vectoring to allow 100/20. Line attenuation has dropped by 50% on TX/RX. Connection has been stable with no drop-outs for several days.

    I've a similar SNR and it's not dropped out once. I think once it stays above 6 it's ok.

    Hi all, just recently got eFibre installed (70Mb/Unlimited package). I'm ~650m from the cabinet, the router stats show a 30Mb link and speedtest results are in the ~25Mb ballpark.

    Fairly ok with that, wasn't really expecting to get the top rate due to distance from the cabinet but just wondering from these stats if I'm on a lower profile than I could be on. Probably more interested in a stable link and unlimited usage rather than outright data rates but fasters always better if you can get it right? :)

    As far as I know vectoring hasn't been rolled out where I am yet so might I be best holding off for that first to see where it gets me?

    Your attenuation puts you much further than 650m... if vectoring improves your SNR another bit then yes you will no problem go close to 50Mbit. Hold tough a few weeks more.

    Thanks for the feedback.

    Using runkeeper app on my phone it's bang on 650m from cabinet to front door but I suspect the cabling takes the scenic route around the estate.

    Will hold off for vectoring to be enabled to see where that gets me.

    Cheers.

    Hi Nonoperational,

    I followed the same methodology described in the bridging the HG658 thread.
    In a nut shell, the items which are hidden have a 'style = display none '
    So I found an item which is visible, found the attainable entries and replaced the style values from a visible entry

    Hope this makes sense ...

    I asked a Vodafone rep on the official vodafone community site [ not on boards ] if he could check my profile and if possible bump it up as I had read that my town had been enabled.
    I noticed the increase yesterday , so don't know if it's thanks to the VF rep or if they have bumped up other users too ...

    My router config with Magnet got a bump in SNR margin a few days ago (increased from ~14dB to 21dB). (It's hard to post a comparison with the stats from VF or other routers, this Magnet one is fairly basic) I'm on 70MB already, does that mean there should be room to move up to 100MB?

    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.
