FTTC in Londonderry - 5Mbit/s

A week ago, I got FTTC installed to my home in Londonderry (NILDW exchange) with the ISP Goscomb replacing ADSL from TalkTalk n�e Nildram. Download performance has been very disappointing.

Speeds per second:
Speed checker estimate: 30Mbit / 7Mbit
BT Engineer check: 37Mbit / 8Mbit
Actual speed: 5Mbit / 8Mbit.

I realise that the engineer's check is going to over estimate the speed as there is overhead to take into account (I wasn't supposed to see the result, probably to stop unreasonable expectations). However, my actual download speed is woeful. It does fluctuate quite a bit, I briefly got 34Mbit/s but often get 1Mbit/s - I think 5Mbit is about average.

I have a Belkin N300 router, which replaced a Belkin Pre-N router which had the same poor performance. Plugging the BT modem directly into a PC also gave the same poor performance. I have a PPPoE connection and the MTU set to 1458, as recommended by BT via Goscomb's support.

Goscomb's support, who it has to be said have been very good and helpful apart from the small issue of getting this fixed, are on it. Which is to say, they've asked BT to get on it. A week later and still no improvement - it's a 12 month contract, I wonder if I can get out of it as they're not delivering what they said.

Well the problem appears to be ISP or equipment related as you appear to be SYNCing at 37Mb, therefore the line is capable of higher speeds.

and run all the tests - you should be prompted to run the third test as your rate is likely to be well below the minimum acceptable for that product.

Hi i live in derry as well and i got fttc and i am getting full speed where`s about do you live

Also on same exchange in Lisnagelvin area and i get full speeds 24/7 with BT Infinity

I live off the Limavady Road, probably just over a mile from the exchange (it's on Irish Street, right?). Johnct, where do you live?

I ran the speed tester a while ago and got about 6Mbit down. The third test (Tap3, I think it was called) wouldn't run. I will try it again when I get home. I'm regretting my choice of ISP, especially as the 80GB cap goes a lot quicker than I'd expected!

The fibre all goes over to NILDM though.

What does speedtest.net give you? what speedtest are you using?

Run the BT speedtest and post the IP profile.

I live near yep exchange on irish street i would say turn off the router for 15-30mins and reboot after this and do another speed test to see what you get
and yes your 80gig will go very quickly !!
