Ultrafast BB (G.FAST) dropping out all the time,

Go to solution

Hi All.

 

Any ideas?

 

I've been running with G.Fast for over a year now (orginal trial customer) and over the past 6 months I've been getting PPP drops but this past months it's got really bad, dropping out mutliple times per day.  I did contact BT about 3 months ago, they tested the line, sent out a engineer and couldnt find a problem.  At the time I changed the DHCP lease time on devices connect to the HH as I thought I noticed a pattern in which mutiple devices would renew their lease and shortly after the HH would spit out a PPP error.  Anyway roll on this last week and it's really bad, phone line seems clear - no pops, static etc.  It feels to me like crappy firmware on the HH as when the uptime of the HH increases the fault seems more common.  I'm ready to bin G.Fast and go back to VDSL which gave me nearly 3 years of faultless connections.

MSAN/DSLAM is located  about 200m up the road - when G.Fast was installed the cable run from the cab to my house was about 300m which I was told was the upper limit of G.Fast.  Home LAN is a typical set up with Cat5e runs around the house connected with a Switch and the HH connected into that.

 

I've attached the HH model / firmware along with the logs.

Unfortunately the mods here cannot help with G.Fast problems as this is dealt with by the FTTP team.

Give them a ring on 0800 587 4787.

@pippincp

This looks like an FTTC connection, not FTTP.

@Keith_Beddoe I know it is but G.Fast is also dealt with by the FTTP team.

The router stats show the the modulation as being G.Fast  and the only number that deal with Ultrafast connections is the one posted by @pippincp as far as I know.

Perhaps there needs to be a redefining of what the help lines are called  or even a minor revamp of this site to include an Ultrafast board to cover both G.Fast and FTTP , not that the posters  get much help at the moment in most of the cases Smiley Sad

Thanks, I will try to remember that.

It just seemed a bit odd to me, but then a lot of the internal workings of BT have always been a mystery, even when I worked for them Smiley Wink

I agree it does seem odd. I think it's possibly because both G.Fast and the higher tiers of FTTP are marketed as Ultafast.

Same product, different method of delivery.

Thanks everyone.  I'll give the number a call but I dont hold much hope. 

FTTP vs G.FAST (FTTC) from what I understand is that both are 'Ultrafast' products with FTTC (G.Fast) being used where planning permission is needed to homes to Ultrafast services.  This esstentially comes down to telegraph wires vs underground wires for the last copper leg.  FTTP is much easier to deliver where properties are connected via telegraph poles as the fibre can be strung off the poles - different story when they need to dig up the road etc.

@oinkman It has nothing to do with planning permission where FTTP or G.Fast  is deployed. By no means all (in fact very little) FTTP is supplied via telegraph poles. This is normally in rural areas where no ducting exists otherwise Openreach use existing ducting. How many roadworks did you see for FTTC deployment? That involved fibre optic cable being delivered to every FTTC cabinet.

The only time any road/street works are required is when blocked ducts are encountered.
