BT Fibre sync speeds

got Fibre 2 (Infinity 2) from Zen a few weeks ago

first time I connected, and quite a few times after that after rebooting router etc I got 50Mbps download

noticed a few days ago I was getting nearer 60Mbps....router must have restarted or maybe brief powercut as I didnt touch it

restarted the router tonight to see what speed it synced at...went back to around 50Mbps, so restarted it again, went up to 54, restarted again and is just under 60 again

is that normal with BT Fibre? or is it likely to be the router/cabling/master socket causing the variation?
 
Stop restarting the hub and let DLM adjust itself.

It'll learn the best sync rate which is stable for your line.
 
ok I appreciate that, but....is it normal to get different sync speeds after a restart with Fibre

with standard broadband the sync speeds were consistent, within a few 100k, almost 10Mbps difference with this. Just wondering if that's normal

if it had stayed at 50 after i restarted the 1st time tonight that would be fine, but it's getting a better sync speed after each restart....have only done it a few times as I know it'll just upset things doing it oo much :)
 
The longer the router stays without a restart, the higher your sync speed gets, due to DLM seeing it as stable and seeing if it can get your connection faster. Just restarting it will make DLM think the line is unstable and will mess up your speed, hence why you're seeing different speeds when you restart as it's trying to find a stable speed.

ADSL is like this as well but it isn't as aggressive as FTTC.
 
Your internal wiring could also be affecting your speeds.

I recently replaced my very old Master socket (Naughty Naughty :D) with a new NTE5 and also fitted a filtered faceplate. I also bought a Cat5e cable to connect the router to the master socket. My speed has improved from about 64/65Mbps to around 69Mbps on a 80/20 package (Estimate was 76Mbps).

I still need to investigate the internal wiring in the loft to see if I can tidy that up.
 
I also bought a Cat5e cable to connect the router to the master socket.

Does this mean you connect a network cable between your router and master socket. My master socket and modem only accepts rj11 style phone cables. Is this something new or are you manually wiring an rj11 plug onto a cable designed for Ethernet? I'd be interested in any way to improve speeds given I sit a mile and a half from my fibre enabled cabinet so it's slow. :(

Do you have an NTE5 Master socket ? Are you using a filtered faceplate or plug in type filters ?
 
Nope, it's a DSL cable with RJ11 ends. Cat5e is the thicker cable that connects the white VDSL modem to the router and/or router to a PC/TV/etc. But you can use a cat5e cable, you just need to make sure to have the right connectors on both ends of the cable.
 
Yeah you get the cheap flat type cable with Routers. I bought my items from Run-It-Direct who are hopefully not classed as a competitor as they only sell Telecoms gear.
 
Just to add to this, I just bought a TP-Link AC2600 router. It's currently connected to the faceplate by RJ11 to it's RJ11 DSL port. High quality cables on the internet are RJ11 to RJ45.

Will the router acceot the VDSL connection (Infinity 2) through it's WAN port if I buy a 0.25m RJ11-RJ45 cable? I'm trying to eek out the best signal I possibly can. The original cable is from a BT Home Hub.

Does that Router have a built in modem ? Or are you using a separate modem ?

It has a built in modem (I've bypassed the old Openreach modem), so I assume I have to go through the DSL port or I'll end up bypassing the modem?
 
I'm with Sky but I've got up to 15Mbps variation in sync speeds over the two months I've had it. Seems normal from what I can gather.

Yeah if you have a DSL port then you connect from there to the faceplate. That is how I do it with my TP-Link VR900.

If you look on run it direct website they have the vDSL Cat5e patch leads with RJ11 to RJ45. That is where I got mine from.
 
There seems to be two versions of the AC2600, does the one you bought state it has a VDSL modem?

I think it's the C2600 (sans modem) and the AC2600 which has the VDSL modem. I have the latter.

This is still confusing me. The DSL port is RJ11, not RJ45 isn't it? I'm going to have to check when I get home! The shot below is the back of the modem, an RJ45 won't fit into there will it? (Again, guess I should try when I get home)
