50Mb connection feels laggy (power levels?)
 

Hi,

I'm on the VM 50mb broadband, and although I get full 50mb on speed test the web browsing seems a little laggy.

Could it be anything to do with my upstream power levels being too low? Also, my SH2 co-ax cable has a (forward) 20dB attenuator as my property is very close to the cabinet and the tech used one of the higher taps.

Re: 50Mb connection feels laggy
 

Can you describe what you mean by "laggy"? If you do a ping test, do you get high or intermittently high pings?

Set up one of these to get a good graph of your connection: http://www.thinkbroadband.com/ping

Honestly though, if your latency and speeds are fine, then any "lag" you're feeling is probably your computer.

Re: 50Mb connection feels laggy
 

When I say laggy I mean websites at times seem to load slowly. Ping test to bbc.co.uk averages around 28ms.

Re: 50Mb connection feels laggy
 

Have you tried a different browser? Preferably one without any addons installed or whatever.

Re: 50Mb connection feels laggy (power levels?)
 

can you zero those rs errors as well and then we can take a look at them again this evening

Tbh dude I wouldn't start worrying about it atm. I know my connection is absolutely fine but I noticed first thing this morning that most websites weren't loading as fast as they normally do and it has got worse throughout the day. Your connection within VM's network might be mint but you have got to remember that it is Sunday afternoon and loads of people all around the world are sat at home so there might be a heavy load on some sites.

Re: 50Mb connection feels laggy (power levels?)
 

I've reset the counters now (5.20pm).

Re: 50Mb connection feels laggy (power levels?)
 

I have just spat some squash all over my keyboard. I was typing out "I wouldn't worry about it too much dude, it has just taken me 3 seconds to load this page" and then I remembered I had some torrents running so I had a quick look to see how much juice they were taking up and nearly died:

I know it is a bit small but it says 1.9MB/sec up and it is holding between 1.8 and 1.9

Re: 50Mb connection feels laggy (power levels?)
 

^^ That would probably account for your slow connection! :)

Here's another download stats taken just now after light browsing (which probably doesn't help much):

Re: 50Mb connection feels laggy (power levels?)
 

Those power levels are fine and you havent got any more post rs errors

Re: 50Mb connection feels laggy (power levels?)
 

I suppose why the browsing has felt a little better too. Oh well, I'll keep an eye on it, although the lag seems to have been prominent since the latest firmware upgrade (v2.01.03) a few nights ago...

Thanks for your help though... :)

Re: 50Mb connection feels laggy (power levels?)
 

create a thinkbroadband ping monitor like Kush has suggested above and then we'll be able to see if you have got any on going issues. You get a nice pretty graph of your pings which will look like this:

https://www.cableforum.co.uk/images/local/2016/03/1.png

If all is well it should like mine does for the last couple of hours where it is pretty much flat green with a bit of blue and yellow running along the bottom

Re: 50Mb connection feels laggy (power levels?)
 

On their website they state that you need a static IP for the monitor to work. VM do not provide static IP so how did you manage to get it to work?

Re: 50Mb connection feels laggy (power levels?)
 

your ip is semi-static. Unless something goes wrong, you'll pretty much always gets the same ip back when your router renews it. I have had the same ip for at least two years and I haven't done anything special to keep it. If I wanted a different one I would leave my router offline a couple of days in the hope that the ip gets given to someone else.

Re: 50Mb connection feels laggy (power levels?)
 

Kinda scary getting so orgasmic you spit a drink over your keyboard because a torrent is apparently going faster than normal.

A bunch of explanations why so not going to speculate just yet. I'm not sure what is being trialled and where, or even if it's just a simple technical issue.

Re: 50Mb connection feels laggy (power levels?)
 

Kids these days...

Re: 50Mb connection feels laggy (power levels?)
 

I was genuinely blown away (pun intended). As pages were taking longer than normal to load I was expecting to see my upstream saturated and thought I might be getting 1MB/sec max with it being a Sunday. When I saw it was nearly hitting 2MB/sec my keyboard got a shower.

Re: 50Mb connection feels laggy (power levels?)
 

Meh, 2MB/sec will be pretty normal for me come next week.

Infinity 2?

Re: 50Mb connection feels laggy (power levels?)
 

How is this out of 10?

http://www.thinkbroadband.com/ping/s...14-07-2015.png

Re: 50Mb connection feels laggy (power levels?)
 

6. The yellow and blue should be a lot less fuzzy. I'll leave my connection idle for today so you can see what it should be like (ideally) (you'll have to wait for it to clear itself throughout the day):

https://www.cableforum.co.uk/images/local/2016/03/1.png

Re: 50Mb connection feels laggy (power levels?)
 

Yes. Rather suspiciously, a few days after I wrote a complaint to Openreach some fibre contractors dug up my road and suddenly I have FTTC available.

I suspect the events were connected in some way but I just can't put my finger on it.

Re: 50Mb connection feels laggy (power levels?)
 

sweet, so do you think you'll get the full 76/20? Have you had a look at the speed estimator thingy? I have just had a look and I think it has gone downhill but they are obviously trying to cover their asses. They have been quite specific the last couple of years are said 53/13 as a minimum but now it says 45-64mbits download and mentions nothing about the upload.

Re: 50Mb connection feels laggy (power levels?)
 

Almost certainly, yes. Less than 60m from the cab and line length of about 80m.

Estimate is 70-80Mbps down, 20-20Mbps up (Clean) and 60-80Mbps down, 12-20Mbps up (Impacted). Last place had almost exactly the same estimate on exactly the same cab and was getting full 80/20 (with headroom).

Re: 50Mb connection feels laggy (power levels?)
 

Surely that's somewhat coincidental? It takes weeks to get that kind of approval, surely?

Re: 50Mb connection feels laggy (power levels?)
 

Let the man think that his complaint resulted in previously unplanned street works to be planned and implemented within a matter of days, it harms no-one :)

Re: 50Mb connection feels laggy (power levels?)
 

I'm sure it's entirely coincidental. But still a suspicious sequence of events. The irony being, after I complained about them giving inaccurate fix dates, they gave me an even more inaccurate fix date

And I thought my sarcasm detector was bad...

Re: 50Mb connection feels laggy (power levels?)
 

aaaaah, has somebody's feeling been hurt? :ghugs:

Re: 50Mb connection feels laggy (power levels?)
 

Not me, I have fast internets again :D

So fast that remote desktopping to my home PC to get my modem stats isn't a complete chore anymore :D
Evidently, a lot of crosstalk, but just look at that upstream margin! I could be uploading at 30Mbps!

Re: 50Mb connection feels laggy (power levels?)
 

I would love 30mbits up. A long time away for me unfortunately (if VM ever get there).

Edit: I would hazard a guess at 10 years which is when I expect they'll be cracking on with fttp or some equivalent

Re: 50Mb connection feels laggy (power levels?)
 

I don't think it'll be that long. Within 5 at the outmost, if you ask me.

Re: 50Mb connection feels laggy (power levels?)
 

Good point, we'll be on 500mbits in 5 years time and it will need 30mbits up minimum

Re: 50Mb connection feels laggy (power levels?)
 

Meh not really; 500Mb will run fine on 15-20Mb up.

30Mb/s up won't take 5 years; I'd say you'll be seeing 30Mb/s+ upload speeds on VM's network in production to some scale in 12-24 months.

Re: 50Mb connection feels laggy (power levels?)
 

I don't think. I imagine the next tier is going to be 300/20 and going by the last 3 lots of upgrades it is going to take them a year and half to roll it out and then they are going to be doing even more relief work and what I am assuming is going to be shub3 and 16 channels down and hopefully 8 up. We can put a calendar up now and start taking bets if you want. I am going to go for two and a half years time so my bet is announcement in November 2016 for rollout to start February 2017.

Re: 50Mb connection feels laggy (power levels?)
 

You're going for two and a half years' time and have given dates a year and a half away? :)

Re: 50Mb connection feels laggy (power levels?)
 

yup, I am going for a 1.5 year rollout out + .5 year delays + .5 year testing new cpe/capacity upgrades/channel bonding

Arse, I see what you mean. I am going for November 2017 announcement with rollout starting February 2018

Re: 50Mb connection feels laggy (power levels?)
 

Given the current, relatively consistent, ratios on the tiers wouldn't 300/24 be more appropriate?

Re: 50Mb connection feels laggy (power levels?)
 

2 of the 3 tiers run with upstream of 6% of downstream speed though, and until the 120->152Mb upgrade upstream was 10% on the top package?

Unsure where you're getting 8% from, 152/12 is the only time I've seen that ratio on VM products?

Re: 50Mb connection feels laggy (power levels?)
 

I am going to have to start triple checking my posts. I missed "so" off again.

Re: 50Mb connection feels laggy (power levels?)
 

I fail at math.

Remind me what the current tiers are again? 50/3, 100/6, 152/12? Somehow I had 3-6-12 in my head and jumped to 24.

O/T Necro:

Swapped to a Rev 2 HH5 and also disconnected long-ass extension wiring my flatmate left connected, maximum data rate has gone up to 92/33

Re: 50Mb connection feels laggy (power levels?)
 

Nice!

Re: 50Mb connection feels laggy (power levels?)
 

And we're pretty much already at worse-case scenario for crosstalk, some vectoring with a tier increase should have us at 120Mbps download :)

Re: 50Mb connection feels laggy (power levels?)
 

120Mbit download I am not bothered about, but that upload is sweet.

Re: 50Mb connection feels laggy (power levels?)
 

No plans for vectoring beyond an extremely 'tactical' deployment to increase coverage of 'superfast' speeds to achieve regional targets.

No plans for a new speed tier.
