Speed issue..

Estimated speed was 71 - 80.
Max throughput speed at the best of times with wired connection - 60
Max throughput speed at the best of times with wireless connection - 42

Why is there such a significant drop in speed on wireless?
Wireless laptop is in the same room as router.!!

Because the Sky Hub only supports 802.11n which is not that fast. Also wireless speeds are heavily influenced by proximity to the router and the device used e.g. phones are slower than laptops generally.

The Sky Hub will report your exact connection speed, so you can check if wired speeds at hitting the mark.

Other people using other wireless networks in nearby homes can affect your wireless speed.

Sky Hub only supports 2.4 GHz which gives less choice than those that also support 5 GHz when there are a lot of people using WiFi around.

Because the WiFi cannot transmit at that speed.

Wireless N is rated at, iirc, 300mb/s. So a real world transfer rate of about 35MB/s

So, getting 42MB/s is pretty good.

The laptop I tested speed on is within 10 feets of the router...
Yes speed is low on mobile - 29 mbps.

How do I find out speed reported by sky hub?

My account says if line speed is 63.6 mbps or less, it is significantly lower than my estimated speed. And if they cant rectify it I have option of leaving.

Which speed are they referring to here? Is it throughput on a wired connection?

Hmm thats bad to do an inferior router then.
Probably neighbours are with ISP s who give a better hub!!

Really?
If thats the case there isnt any benefit of taking package of more than 38 mbps as most people use internet wireless.
So I think people should be getting better speed on wireless too..

Anyway whats a reasonable / usual percent drop in speed on wireless (compared to wired) provided the laptop is sitting very close to the hub?

Same place as adsl stats

I tried both urls > http://192.168.1.1/sky_system.html and http://192.168.1.1/

but getting the message this page cant be displayed..!!
tried in opera and IE.

If so close to the router then why don't you use Ethernet all the time ?

Hmm.. I dont sit that close with laptop always..
I meant the speed I posted was at that distance..
And if I go upstairs speed even drops which is understandable. But I cant digest the significant drop when very close to router or at least in the same room of the router..

I think this is the easiest way to find your connection speed on Sky:

http://broadbandconnection.sky.com/speed-finder

Alternatively, the router actually runs on http://192.168.0.1 (username: admin, password: sky).

The speed they will be referring to is the speed you get when connected to the router with an ethernet cable.

Any provider who lets you leave because you have rubbish WiFi speeds is not going to be around very long.

WiFi is such a pain in the rear end, I only use it for my tablet and phone, and thats only because they dont have ethernet ports.

Anything that has an ethernet port has a cable in the thing. Its the best way to make sure you're getting the speeds you are capable of.

I will say though, my Home Hub 4 on the 5Ghz connection to my Galaxy S4 does give me the full (give or take a mb or two) the exact same speed as my ethernet connected PC.

No, ISPs only ever quote connection (sync) speeds. That is all they have control over.

ISPs don't have any control over sync speeds on fibre. They are obviously referring to throughput.

Obviously? How about, e.g.:

In reference to www.dslchecker.bt.com/adsl/ADSLChecker.TelephoneNumberOutput:

Downstream Line Rate(Mbps)

Throughput/download speeds will be less than line rates and can be affected by a number of factors within and external to BT's network, Communication Providers' networks and within customer premises.

Perhaps "control" was too strong a word for you. Maybe "influence" will suit you better. Don't they influence the various connection parameters controlling the DLM?

The ASA guidelines indicate consumers should do speed tests to confirm what they have been sold, not check their sync speeds.

Your link says ADSL, but this thread is all about fibre as I said.

What linkh? You mean the one that starts:

Featured Products Downstream Line Rate(Mbps) Upstream Line Rate(Mbps) Downstream Range(Mbps) Availability Date

High Low High Low
FTTC Range A (Clean) 80 64 20 20 -- Available
FTTC Range B (Impacted) 79.6 52.9 20 12.2 -- Available

Linky?

Do you agree this thread is about fibre not ADSL so ISPs cannot control the sync speeds?

No. DLM is controlled by Openreach not the ISP.

Yes, the speeds quoted by any ISP are sync speeds for all DSL regardless of who 'controls' them. That is the point I am addressing.

I think ISPs have two options, Stable or Super Stable and that's it. Most probably don't know they have these options.

3 options, "Standard", "Stable" and "Speed". I'm not sure if those are the official names though.

I can't see those options affecting the sync speed though, only the throughput.

I think they just affect the error thresholds for DLM.

And if interleaving kicks in fttc takes a sync speed hit, hence G.INP now appearing

I think G.INP is more about throughput not sync speed.

My line has improved interleave, now only depth 8 rather than depth 1021, and I've seen download speeds improve by a few meg. However upload is worse, but my logs are incomplete.

Seen people lose sync speed at the same time interleave is switched on, and see some gain some of this back once G.INP appears.

Interleaving on VDSL2 has always been a much harsher tool than it was on ADSL/ADSL2+

The further from the wireless aerial the slower your WIRELESS connection will be. Once a wall or floor is between the aforementioned the connection will be considerably slower.

Newer houses have plasterboard walls with a foil backing for insulation. This causes a wireless signal to struggle even more.

We can't have everything. Lower heating costs or great wireless signal.

What is the wireless modem built-in to your laptop? Try an external USB adapter.
