Title: Vodafone up to 76mbps DLM profile and latency
Post by: N0STIE on January 13, 2020, 10:04:00 AM
Hi,

My Plusnet contract ends this month and I am thinking of signing up with them again due to low latency (10ms).

Just seen Vodafone deal for existing customers as I got mobile contract with them. They offer up to 76mbps for £17.50.

Anyone already with their fibre package and can give me any opinion? What DLM profile do they use? Will it give me around 10ms as Plusnet do? How's they like stability etc?

Thanks!

I’m on Vodafone and can test.

But a 10msec ping to where? :)

@displaced

To servers in London, BBC, multiplay.co.uk etc.

Preferably from north west

I can only speak from my experience, but I've been perfectly happy with Vodafone, at least after a wobbly start.

If you do choose them, here's a tip: Ditch the Vodafone-provided Huawei HHG2500.  It's junk. 

I had 4 years of totally stable BT Infinity via an Openreach HG612 modem.  After switching to Vodafone, their HHG2500 router lost sync several times an hour, causing my line to be banded.  I got my PPPoE login details from Vodafone, reconfigured my existing HG612 with those details, and eventually got Openreach to reset the DLM on my line.  Since then, it's been great.

In two or three years with them (can't quite remember!), I've had maybe two disconnects and one case where there was noticeable congestion.  I think I recall that was due to a router failure on their side, rather than run-of-the-mill congestion -- and lasted only a few hours.

I can't speak for how good their DNS or Email services are, as I don't use them -- I've got email hosted elsewhere, and use a local caching nameserver that delegates lookups to Cloudflare's 1.1.1.1 service.

[edit to add:  I'm on the 76Mbit service, but my line is ~620m to the cabinet, so I get about 60Mbit down/10Mbit up with G.INP/interleaving etc.  So not a terrible line, but not a great one either.  Of course, that'd be the same no matter what VDSL ISP I use!]

Yep, they are!  In the first month or so they were handing them out. Then by the time I signed up they’d changed their policy and I had a good 4 hour argument to get my details.  About 3 months after that they withdrew the ‘our modem only’ policy and now hand out the info without any quibbles.

Standard

@kitz can you clarify as I am a little confused by this, so is it Standard of NGA FTTC or WBC?

ISP's known to use NGA Speed Profile: AAISP, BT, Plusnet, Zen.
ISP's known to use NGA Standard Profile: EE, Sky, TalkTalk, Vodafone.

So are we looking at NGA Profile (FTTC) or WBC 20/21CN, because they say different things for different ISPs.

Does that mean it will perform the same as Plusnet in terms of reliability/latency or worse as Plusnet use Speed profile as of NGA FTTC?

On the other hand, what DLM profile do Zen use as I am also considering them. Is this information up to date?

Thank you!

Vodafone use the NGA Standard DLM policy.

So most likely my pings will double compared to PN? I am on ECI cab 80/20 full sync very stable line 300m from cabinet

VDSL Link   Downstream   Upstream
Connection Speed   79995 kbps   20000 kbps
Line Attenuation   11.9 db   10.6 db
Noise Margin   11.3 db   9.8 db

Some stats from D7000 v2

Why? I changed mine from BT to TT and my ping remains at about 8ms to bbc.co.uk or google.co.uk
