HELP New E-fibre install - intermittent access F2000

jones

Folks,

Just want to pick your knowlegable brains on my issue.
Basically i had a new efibre line installed last tuesday in my home. It's on a "country road" so we're only getting 9mb fibre and i was told this before installation. We were previously on 3.5mb so this was amazing news to us and we were told the very nature of e-fibre we'd have a lot less issues. Previously the old dsl connection would go every few weeks/months with problems on the line.

My problem started exactly a week after installation. For the first week everything was humming along nicely we were getting great speed and the F2000 modem was a joy and played nicely with all my devices. We praised to lords for efibre and even with the measely 9mb, by other peoples standards, worked brilliantly for us. Netflix, PS4, spotify, general internet use was all instantaneous.

Tuesday just gone i noticed something was not quite right, the modem appeared to be working (all lights on DSL, internet etc) but when i tried to get anything from online it basically froze and then returned a screen to say could not connect to internet. I logged into the F2000 modem and it told me everything was perfect but no matter what device i used to connect to the internet (both wired and wifi) it would just hang as if there was no internet. If i do a reset be it hard or soft reset when the modem turns on initially it seems to work perfectly again for a few minutes before the back hole returns. this cycle seems to repeat through the day but it appears as if it has never stopped working according to the modem and eir's line tests.

Basically it seems to have intermittent connection problems but the modem itself tells me everything is ok. Eir checked the line and can see no issues either but they also couldnt access the modem at certain times while i was experiencing these issues and they couldn't tell me why so they are sending me out a new modem claiming the wifi might be dodgy on that particular box. The problem is even cabled in the internet keeps going intermittently so i'm not sure what the WIFI has got to do with it.

Any ideas? I am hoping its a dodgy modem as that's the easiest thing sorted but it's strange that it worked perfectly for a week and does seem to work after a reset or some sort.

Thanks and sorry for the long winded post,

A very frustrated Jones

9Mb isnt a profile they use, so its set to 10 or 12 and "doing its best"(Rate Adaptive). If theres anything wrong this will cause regular drops. Have them lock you to 7_1 and hope its stable. If you're out at the 1800m+ range your upstream attainables may be barely 1Mb or less, if thats the case, cancel and revert to ADSL, you won't get it fixed.

Thanks for the reply,

It was originally 7_1 but they turned it up to 9.1mb the other day they said that can sort certain problems out. It must be the adaptive rate your talking about as eir didn't know what speed it was until he changed it.

Speed tests have my upstream at exactly 1mb at the moment and download around 8.5mb. Is that sufficient?

It's just odd as it worked perfectly for a week with a lot of heavy traffic on it (I'd been offline for 3 weeks so I'd a lot to update) surely if it couldn't handle the fibre it would of crashed straight away?

Nope. Your usage doesnt have a huge amount to do with it. Eir support were ill advised upping your profile.

Copper lines pick up noise from other lines and everything electrical nearby them. Within the 2KM of cable you're on there are probably plenty of noise sources. If a line runs at 90% then if theres a little burst of interference it can usually handle it, but if its 100% the ratio of signal to noise is such that bursts of noise cause it to give up and do a full reconnect process. This takes 1.5-3mins during which you have no connection.

Have them lock it to 7_1 again and hope that holds.

The Very odd thing is since they upped the speed I haven't had a single issue.. touch wood. I logged onto router and checked settings I'm getting the following info:

Upstream noise safety coefficient 8.2
Downstream noise safety coefficient 9.4

Upstream line attenuation 23.9
Downstream line attenuation 35.3

This means nothing to me of course but does it mean anything to you?

Thanks for your replies on this

Just to update anyone interested, my efibre has been perfect ever since this droppage (TOUCH WOOD). Eir sent me a new router but i'm not going to change it unless this happens again. I'm not even sure what the new router could possibly change as i dont think its anything to do with the router.
