Hello all,
I am very new to the delights of FTTP, as until last week I only had access to FTTC. I was wondering if any of you, more knowledgable, types might be able to answer a question for me: "What 'settings' do I need for my router to correctly use the FTTP service that is provided by OpenReach via my ISP?"
First of all, perhaps I should state what my (probably somewhat inaccurate) mental model of the set-up is and what I have observed, and then someone could explain what I've missed or misunderstood...
Mental model: OpenReach provides a physical connection via the fibre network which terminates at their ONT in my premises. This ONT then provides an ethernet port to which I can connect my router and network. The logical layer uses PPPoE - my router authenticates via a username and password and gets an IP service via ethernet (from the ONT.)
So - am I right in thinking that, as far as the end user is concerned, the service is pure Ethernet from the ONT - all the configuration needed is that PPPoE auth?
Here's what I have observed:
1 - My ISP (Zen) provided a pre-configured FritzBox router.
2 - On installation of FTTP and the ONT both the OpenReach engineer and I were surprised to see poor speedtest results: fine upload speeds (30mbps as expected) but terrible download speed (about 20mbps). He stated that "usually you just plug in the router and it hits the speeds straight away."
3 - I phoned Zen's tech support and a very nice man suggested that I set some settings in the Fritz Box (a couple of fields named 'throughput' up and down.) I did and this solved the problem.
4 - Later I wanted to use my own router instead (a Ubiquiti Edge Router) - this only had two settings for the PPPoE link (auth and MTU). Initially it worked very well, but after a few hours it fell back to download speeds of about 70mbps.
5 - This page (https://community.ubnt.com/t5/EdgeR...th-UK-FTTP-PPPoE-to-BT-Openreach/td-p/2224875) suggested that altering the MTU would get correct speeds. Adjusting the MTU did indeed get better speeds 130mbps (almost as high as the Fritzbox 150mbps but not quite.)
So - my question is this: What are the 'throughput speed' settings on the Fritzbox (I've never seen this kind of setting before) and why didn't the FTTP service work correctly without them? Are they just a different way of setting the MTU? Are there any settings to do with FTTP that a router should provide that my Edge Router doesn't?
Thanks
