I had to ask Cerberus for my PPPoE details as the OR installer was setting up the ONT. I received it within a few minutes.

I see, I'll sort that the day before appointment so I have ample time to prepare things my end, unless it ends up being on Monday in which case I'll have to ask on the day first thing. Thanks.

I couldnt find an answer to this question when scanning the previous threads, does Cerberus provide a router/modem or do we have to get our own?

I know people prefer using their own kit, which is understandable, but do we get anything from Cerberus as far as router/modem?

No they don't provide a free router on FTTPoD - you can buy one from them if you want:

Zyxel VMG3925 ADSL2/VDSL2 FTTC 802.11ac 1600 Wireless Router - £79.00
Delivery - £11.25

Hey, sorry I've been travelling with work this week and just got home.
So latency is probably the best I can expect. I can't really complain too much.

Guess my next question why my single thread speed is so slower Typically around a third of my multi (80-110mbps)

I saw a few of you guys getting 4-6ms

Depends on how far away you are from London, where your ISP's POP is likely to be, as is whatever it is you're pinging.

Light in a fibre optic travels at about 200,000 km/s. So every 100km further away you are adds another 1ms to the round-trip time.

I am on FTTP and about 3.5 miles (bird's-eye view) from Telehouse and I get the following:

Hi

How are you testing? Is it wired Ethernet from a Windows PC?

If a Windows PC, it might be worth resetting your network back to defaults (search for 'windows pc reset network stack'), this is in case anything has played with the network settings.

What router are you using? Where you on VDSL before? If so did you have any similar issues with single thread being below multiple threads? What speeds do you get if you go to speedtest.net and use the single thread option?

Regards

Phil

Ethernet wired and same results on different laptops.

Good point on resetting the network stack. Will try that and will update.

Router wise, I'm using an Ubiquiti AmplifiHQ. I did have VDSL before but never tested single Vs Multi thread.
I'll try an borrow a different router and see if that shows any different results.

Results are the same/similar at speedtest.net so at least I know it's TBB's speedtest.
Could peering be an issue at the exchange?

I'll raise a ticket with Cerberus to see if they can look into it. I wasn't home when the connection was finalised so didn't see the engineers results but I'd assume they tested both single and multi.

Thanks

Ohh, i'll probably create a separate topic to save cluttering this one.

You should connect your laptop directly to the ONT without using your router and check your speeds to rule out an issue with your router. Also check you don't have any QoS or traffic shaping enabled which may be limiting single threaded speeds.

The OR installer doesn't perform any speed checks - they just check the light signal levels.

Sadly no news from Openreach about a confirmed appointment, which either means they could turn up by surprise on Monday morning early, or that they might still turn up some point next week, or possibly more likely they won't turn up until the week after by the time a confirmed date is given.

They definitely won�t turn up unannounced, so I would just sit tight & wait for the call. For my install appointment, they (some Openreach Manager) called me a week in advance and asked me to choose a time slot for the following week.
