FTTP (Sky Ultrafast Plus) Speed Issues

Hi

Just had FTTP installed by OR, Sky Ultrafast Plus (min 400mbps, advertised 500mbps), was installed on Friday.

Since then I have had nowhere near the advertised speeds. Have not hit 100 even yet, wired in direct to the Sky router. Tried with another 3rd party router and getting the same.

Spoke to Sky and they said that it takes two weeks to "ramp up and settle" - I am aware that can happen on a DSL line, but I thought Fibre would be bang, there it is?

Anyone else had similar experiences, and is there anything I can or should do?

Sky is wrong: the full speed will be available as soon as it's installed.

Most likely the problem is with your end device that you are testing with: ultrafast speeds are very good at highlighting these limitations. If it's a Windows device, then antivirus and NIC drivers are the top two suspects.

Quick way to test: burn an Ubuntu Live image onto a USB stick, boot from that, and repeat your speed test.

Or find a friend who has a Macbook and try that.

Even on a poor day any smartphone from last couple of years would easy get >100Mbps on wifi alone.

Sky are trying it on.

If its "wired in direct" then it's unlikely to be a smartphone.

There is another possibility: a bad CAT5e cable, or a broken pin in an RJ45 connector, can cause the ethernet link to drop to 100Mbps. This will show as about 90Mbps on a Speedtest.

This can easily be checked: look at the network adapter settings and see if the detected speed is 1Gbps or 100Mbps.

Go back to them and tell them quite bluntly that they are talking rubbish. If they insist they are not, ask them to "turn up the dimmer" as that is obviously their problem! Then ask for tech support from someone who is actually trained in FTTP issues.

Make sure your network card is gigabit, and make sure it's set to gigabit!

I have Sky FTTP and from the moment it went live, I have had pretty much full speed. It doesn't 'ramp up' there is no training period like FTTC.

Any modern smart phone next to the router should connect at 866Mbps - you can check this in your phone network configuration.

Sounds more like a capacity / potential profiling issue at Sky's end.

Yes as FTTP doesn't involved any ten days training period and no DLM at all. Full speed from first installed.

Openreach FTTC & G.fast - no ten days training period but does have DLM at all times monitoring the line.

The problem at I had with my router was that lan ports were only 100Mb whilst Wlan was 1 gig
Could be cable , as stated previously.
Even my 4 year laptop has Gig ethernet
What do you get with WiFi ?

As has been pointed out above, there is no “training” required with an FTTP service - there is no variable analogue element as there is with FTTC services.l based on line length and noise. FTTP is *not* influenced by distance as implemented. Perhaps the Sky first line support person requires training!

Your issue is one of the following:

1. An incorrect bandwidth/speed profile has been applied to your service which would rate limit the available download and upload speed at the ONT. This is something only Sky can resolve with Openreach. I think it’s unlikely this is your issue though. More likely one of the following….

2. A router (usually customers own) that does not have the capability to pass the full throughput of the service. Again fairly unlikely given the router is ISP supplied and you have swapped with another router with no difference.

3. There is a copper cable (RJ45 patch lead) fault either from ONT to router or from router to your laptop/PC. Even brand new cables that otherwise look fine can be faulty. Ensure that you aren’t reusing old patch leads that only have 2 pairs connected (orange and green) - hold up the RJ45 plugs and you can see what colour pairs are punched down on the pins. Otherwise ensure they are ‘all pairs’ straight-through patch leads. Best to check on all kit that physical link speeds are at full duplex gigabit. Swap or get fresh leads as needed. Faulty leads will as noted generally manifest as connections which default to 100 Mbps rather than 1000 Mbps.

4. Your laptop/PC is either too old or too bogged down to be able to exercise the full bandwidth available. Usually this means on a direct cable test, the machine can achieve more than 100 Mbps but less than the full bandwidth. Typically a few hundred Mbps.

Given what you say about rates being less than 100 Mbps, I think you are quite likely looking at a copper cable issue.
