They're looking very nice now, apart from the upload speed which hopefully Vodafone will fix.

My downstream SNR has risen to 15, does anyone know what that means?

Vectoring has been turned on...... It's getting repetitive at this stage...

Vectoring has always been on for me as I only joined Vodafone recently.

Apologies for the questions, I'm just not sure what they all mean!

How can you be sure? I also only joined VF recently but AFAIK vectoring is not enabled yet, at least I hope not, because currently I'm only getting 30/8 and am expecting a significant improvement once vectoring is enabled!

I sync at 100/20, if I wasn't connected to a Vectoring enabled cabinet I'd only sync at 70/20, if not less.

That's how I can be sure! :pac:

This is correct. Have to be vectored to breach 70mb mark.

Snrs fluctuate though. Don't read a huge amount from it. That said, it could mean a change from card vectoring to dslam vectoring. Or it could be nothing.

Yeah I'm not worrying about slight changes too much but I find it interesting to see that it does change.

Could be due to the fact my modem has been on for 30 days though :P

Well just had a technician out again and he again confirmed my upload stats from the socket showing over 21mbps yet I am only getting 11-12mbps over wired/wireless/homeplugs. He showed my the stats on his meter and download was 128mbps attainable and upload was about 24mbps attainable.

The technician also told me that Eircom/KNN would have to charge me up to €400 if they were called out again for no reason by Vodafone.

Is it not strange that the download speed drops significantly when wired changes to homeplug connection then drops again for wireless connection yet there is no difference between the upload speed for all three connection types?

This is normal.

The download is much faster than the upload so it gets throttled much easier. On gigabit ethernet you have 1000Mb each way, plenty to run your VDSL over. On homeplugs say you have 70 each way, that limits download, not upload. On Wifi say you have 40 each way? Limits download more, still doesnt limit upload.

Okay so efibre was installed on Thursday and while it defiantly an improvement I can't help but feel like the it should be better than this, the guy who installed it said the speed should increase when the "line settles down"
is this true or was he just making stuff up??? if it is true then how long does this settling down process take???
I'm approx 250m from cab

Are you sure you're 250m from the cab? The attenuation is very high which would suggest either you're connected to a cab much further away(8-900m) or there's a line fault.

These are my aunties stats.

Sorry if the layout isn't right as I'm on my phone.

What's the distance from the Cab would you think?

Can the line take more?

Thanks.

The cabinet is a good bit away, the estate is very long and her house is at the back!

The cab is outside another estate but I think it serves this one too.

I wonder is this particular profile rate adaptive or is it set?

Can't say if its FR or RA but either way its syncing at the best it can right now.

If the area happens to be unvectored then she might make 60 later.

It's still in Carlow so I'm guessing it's Vectored.

Very far away from the cabinet walking distance.

_Whimsical_

These are my stats.
Obviously I'm pretty disappointed with my speeds so far. They range from 1mb up to 20 on a good day. The cabinet is on my road so it's only a short distance away. These are wireless speeds but homeplugs so far aren't much improving things. Sometimes they double the speed.
Is there anything in the stats I should be concerning myself with ?

Thats a good sync. Somethings wrong. Most likely wifi/homeplugs.

Can you connect a laptop directly to the modem with an ethernet cable and run a speedtest?

I did and I got 94mb pretty consistantly over the day.
I have tried homeplugs wired that get me around 35-40 mbs but even with the wifi extender and boost on the homeplugs the highest wifi speed I've seen is 14mb, and thats not consistent.
I really need wireless in my house though.:(

The question is do you really need 94Mb wireless? Probably not.

10-15Mb would be more than ample for the vast vast majority of cases. Any devices/systems you have needing more than that should be wired rather than wireless.

Personally I don't like the thoughts of running data along electrical cables - it's never going to be as reliable as using proper dedicated network cable, especially as you add more of those devices and if your wiring is old or a bit of a mess.

The booster slows you down! Get rid of it.

Good homeplugs CAN work. But not always. If somethings making noise on your grounding then they slow down.

TBH if you're paying for a good connection(€50+ x18 months) may as well invest in some decent gear to use it. Run some CAT6 into the middle of the house and connect a high end wireless access point there, that should give you better results. 5Ghz is a good idea if its an apartment or terraced house.

Well I use it for downloading and for streaming, which is now buffering an awful lot,I used to never experience much buffering and stopping and starting. Also I had dead zones in the house now.
If I'm paying for a good connection,and capable of receiving it I'm not happy that I'm stuck with a wifi router than essentials chops 90% of it off and causes me problems.

I would have no idea where to start with running wires etc and it's not my house so it might not be so welcome.
How do you mean the booster slows you down?

ED E

Think of wifi like walkie talkies. You talk, over, they talk, over. And so on. Cant talk together.

When you use a booster:
Router "Hello"
Booster"I heard you"
Booster"Router says hello"
Laptop"I heard you"
Laptop"Hi Router"
Booster"I heard you"
Booster"Laptop says Hi Router"

Not very efficient as every action is doubled but the signalling rate is the same.

They have their places where really needed, but are a last resort.

If you're renting, try and optimize the homeplugs. Dont put them on power extension leads, direct to a socket only, and try turning off all other devices to see if something is affecting them by trial and error.

ED E I loved your little analogy haha :P

I have cat 5 cable going into a few rooms in my house but I really should've used cat 6 for future proofing!

I would recommend that they buy a good 802.11ac router over Home Plugs as they seem to be quite iffy in use.

I have decided to give up on Vodafone who's only answer is to send the Eircom Technicians out yet again to check a line that is perfect. Eircom/KNN have told me they will definitely charge the next time they are called out and it will be in the region of €400 and it is the householder that is charged.

Rather than become piggy in the middle between Vodafone and Eircom I have decided to contact ComReg and ask them to investigate why Eircom can prove my line speeds are 128down and 20.8up yet Vodafone can only provide less than 13Mbps from their modems.

My stats as of today, Is the upstream output power supposed to be a minus figure?

Your download speed jumps right up when connected directly to the router. As suggested above, your upload should be much closer to 20Mb though.

My download and ping is very similar to yours, I guess your upload should be very close to mine also:

I am beginning to think that the difference in upload speeds might have everything to do with the ISP.

Can anyone on the 100/20 profile with Vodafone post their speeds to compare please

Read this tread and you'll find some Vodafone customers with 100/20.

It is the ISP but I believe it's because of you upstream noise margin (upstream SNR). Vodafone limit it to 9.0db, which prevenst more speed on your line - at least is does for downstream SNR, so I reckon it's the same for upstream SNR.

I don't believe Eircom limit their SNR to 9db, but you'll have to confirm that with them. If they don't limit it, I suggest switching to Eircom if you want faster upload speed. If I was in your position, I would switch for higher upload speeds.

The lowest the SNR can go is 6db before you usually have intermittent disconnects or "drop-outs" has they're called.

AlanS181824

If Vodafone's max upstream line attenuation is 9 and mine is 2.2 then does that mean that there's potentially a lot of room for a better upload?

I hope that soon Eircom allow for 25Mb or even 30Mb upload speeds.

Foggy Lad I've posted a few speed tests of my 100/20 connection on this thread.

I'd post a new one only I'm On my tablet.

airuser

I am still on NGB. Have been following this tread with interest. A couple of questions.

Can EIRCOM dictate the speeds provided to others?

Or

Are non Eircom providers unable to provide speeds which they advertise?

According to a recent article I believe published by "Silicon Republic", ISP on average only supply about 75/80 % of the published speeds.

Please forgive me if I am on the wrong forum for these question
