I went to Sky fibre over 12 months ago. From day 1 it has been stuck at 37.6/8.6. No limits, no droppages, no buffering.

My ADSL with Sky was miserable - more to OR cabling than anything else, but since FTTC - brilliant!

Ive already opted for plusnet but SKY are cheaper. Is SKY Fibre any good? OR should I stick with Plusnet?

If you've already opted for Plusnet, aren't you on an 18-month contract? You would have to factor in the early termination charges (which don't amount to the full cost of the remaining period, but nevertheless need to be considered).

P.S. I have found Plusnet FTTC to be brilliant, personally, but others may beg to differ.

P.P.S. Looks like I went back to fast path again at 4am - see BQM!

Yeah Im going to stick with Plusnet. Think my mind was already made up. As I said, Ive had a bad experience with SKY so its time to give Plusnet a go

When is your install date?

Sorry Ronksi, I missed this reply, think I had forgot to put me reading glasses on. The installation date is 19/09/2013. A couple more of my neighbours have upgraded to fibre optic. They have chosen BT Infinity. Looking forward to having my infinity installed next week.

Lucky you having the cab just across the road

Bare in mind that PlusNet have UK support, whereas BT's is a foreign call centre.

Also with Plus Net you can get a referral discount, so could in theory if you refer enough people get your broadband for free, or they even end up paying you money. If you go with PN ask your neighbour for their referral code, which is their username.

It's possible Sky have not installed their link at the exchange yet. ISPs that use their own back haul like Sky & TalkTalk need to link the FTTC equipment to their own equipment and need to get a special link installed, sometimes they can be a bit slow getting this done.

Why is this lucky? Im curious because I didnt think distance mattered as much with fibre Optic?? The cab is about 20 metres away from my house (give or take a couple of metres). As I said, my install date is 19th of sept. Kind of looking forward to it

Thank's to the misleading advertisments that IMO ASA should put a stop to you seem to think(from what you have posted here) it's Fibre optic to your home, FTTC is fibre to the road side cabinet only, the remainder is the very same copper cable that your phone and adsl are supplied on, hence the distance from the FTTC cab, and of course how many joints are in that cable and it's quality ect, so if you are 600mts from the cab you ain't gonna be able to get 80mbps

As Tommy says, with FTTC there is still copper from the cab. The broadband signal on FTTC travels over copper from the FTTC cab to the PCP, from there it joins your original copper line to your house, so the total distance it travels is from the FTTC cab to PCP, then to your property.

I'm around 450 meters, but get only 42Mbps (was estimated 57), some at my distance are lucky and get 60 to70 Mbps, others further away get substantially less, once you reach around 1000 meters you could be as low as 20Mbps. Due to the higher frequencies used with VDSL they degrade quicker over distance compared to ADSL, there are also power masks which limit certain frequencies to restrict crosstalk. Cross talk will also affect longer lines more than shorter lines. When vectoring is brought in this should boost a lot of peoples speeds, and possibly extend the range, but that is some years off, and is only just being trialled by BT. Lines that are made of aluminium, or have many joins will also deteriorate faster and I doubt vectoring will help with these lines much.

The lucky few that live within 150 to 200 meters will most likely get full speeds, so you should get the full 80/20 sync speed, and see speed test results of around 78/18.

That said 42Mbps is still a good speed, and four times what I was getting.

Hope that makes things clear and your install goes well.

Just one thing, if the max IP profile is 77.44 So a max throughput of 73-74mbps could be achievable the upload would be 18 -19mbps
although from what i have read the max thoughput can depend on the hardware used, Both modem/router as well as if pppoe or pppoa is used due to the difference in overheads or was it MTU size as the max on PPPOE is less (1492 ) and i dare say max thoughput and if a customer is able to gwet that max speed 24/7 or not will be down to the ISP and BT or who ever is responsible for the link from exchange to ISP , because if that link gets congested then speeds will slow,

I'm not sure on the exact speeds achievable with a 80/20 sync speed, but they will of course be less. And there will always be a bottle neck somewhere, I have an upload of around 8Mbps, but the highest I've ever seen on my cloud backup is around 3Mbps. Same with download, there will be a bottle neck somewhere, whether it's your link speed or a congested server you're downloading from.

upload speeds are much harder to max out due to buffer issues.

eg. outlook requires a key changing in the windows registry to get fast speeds uploading emails.

basically windows has a quite low default buffer size with each app able to use its own value if coded in, most apps either dont change it or set it optimised for lower speeds. some apps such as ftp clients allow you to set your own value. firefox allows it to be configured so if uploading to cloud via firefox that could help.

try in the registry editing this.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\AFD\Parameters
DefaultSendWindow to 524288 dword32
setting DynamicSendBufferDisable to 0 may also help (also dword32). Each of these changes requires a reboot to apply.

This doesnt work for everything as some apps hardset low buffers ignoring that value and it can also slow some things down.

running this in command prompt will show if send buffer autotuning is on or not.

netsh winsock show autotuning
