My experience with the new Sky Broadband Hub

https://helpforum.sky.com/t5/Broadband/SR203-Downstream-Line-Rate-slower-than-previous-ER110/m-p/343...

Likewise, I'd like to see the research done on the routers and router stats for the comparisons on improvements om SR203 compared to ER110/ER115?

@lettice 

I've never seen the DSL firmware change on the ER110/ER115 when I had one for few years and I doubt the DSL firmware changes on the SR203/SR204 either? As for DSL leads, I understand that G.fast usually has better leads but VDSL2 it should really make zero difference with a fly lead less than 2 metres and twisted in both cases and long as it confirms to standard and that be same on both routers?

I'd rather enjoy talking about why that user has a 7Mbps drop with VDSL2 with SR203 as it a fact proved on the thread. I'd like to now see your proof?

Re firmware, meant it changes with each router model not changes through the life of the router.

Re cabling, the SR203/4 does come with two cables and it does insist on using the correct coloured coded ones.
I agree with you but its just one of those oddities to try, hence mentioning it.

Just read that thread, does seem odd but as I said have not seen it and had a similar swap over very recently, as I mentioned above.

I just dug out my old Sky Q hub Er110 (in fact have a few of them).

It has the same dsl firmware as the mentioned user, the speed was 79987 20000 on there, exactly as I get on my SR203.

Sorry, so long, but the SR203 does seem to take a while resyncing on reconnection when the Q hub took very little time. Have often noticed that.

I know your expertise and did wonder in this specific case, if the swapover is not syncing correctly because of  a mac address issue. 
Does the cabinet and/or cabinet/echange system not hold the mac address and its sync speed and for some reason its holding onto the Er110, but the SR203 is being seen as new/different.

Maybe picking at straws here 🙂

I'm wondering whether it is an issue with the frequency spectrum at the mid to higher end of DS2 band and only related to DSL firmware on SR203 with its interaction with ECI DSLAM? It is certainly an interesting case the thread pointed to and we as a community should just be aware of it, but it is unlikely to impact many lines but worth keeping an eye on those synchronising at around the 50-55Mbps synchronisation with is usually maximum utilisation on DS1 & most of the DS2 bands in general.

There is likely a slightly sore spot in the chipset spectrum utilisation at a set frequency (around 7Mhz?) for that line with ECI & SR203 DSL chipset together. As I realise every line, router and DSLAM has its own unique characteristics but 7Mbps is a lot of difference for just swapping the router over with 300-400KHz wide sore spot!

I'm not suggesting that it would impact every line or that the SR203 isn't good on different types of lines as @jamesn123 has found with another community member.

@lettice 

The poster concerned had an SR203 connected for sometimes as I thought the same as you with DSLAM not adjusting according to the router, line and DSLAM with DLM.

I have taken my new SR203 out and have went back to the SR115.

the signal on the 203 was so unreliable, sometimes down to 0.5mb and it there was nearly riots in the house when the kids couldn't use x box etc reliably.

Put the 115 in and it is much more stable, still drops regularly but much better than the new one.

Havent got a clue why as the 203 was claimed to be much better than previous models.

thanks i was thinking about up dating my broadband but having read the comments on here, i am going to put that on hold, until they sort out all these sort of problems.

having been talked into the q box, i wish i had stayed as i was, being disabled i had 2 tv using the same box, since they installed the q box only one works, so my bedroom set now does not work as the fitter cut it off, saying one box one tv, well it was a fitter that told i could do this in the first place years ago, and every other fitter that had been better the q fitter, has said its ok, you have the booster in the loft and here so its all good, until q.

now i have to have silence when having i lie down, i miss afternoon films.

the last 5 months have been extra hard.

any way thanks for the updates even if i dont always understand what you are all talking about.

is is exactly the same as my experience. We just got tot he stage when using the old e115 router with oiur Q box, 2 minis and powerline adapters to the pc and ps4 that everything was working well enough with no lag to online games.

Go sent the new sr203 by Sky and suddenly the pc and ps4 are lagging like crazy with packet loss regularly.

The powerline adapters are also showing the red light for poor speeds.

Change back to old router and powerline adapters work fine with no lag and all lights green.

Whay would the new router change the poerline adapters so that they can't feed enough data to play without lag?

[mae-3]

@kippercat 

You are certainly not the first to report an issue with lagging on a PS4 with latest SR203 router but without router ER115 and SR203 stats, etc... to compare the difference it won't be known precisely what the issue was in your respect?

[mae-3]

I've looked at the technical information on dynamic spectrum management and notice that power back off on the upstream side has a beneficial benefit to the downstream of about approximately 7Mbps. With this 7Mbps that was lost on downstream with the poster on that thread at the 50-55Mbps mark, I believe that the upstream power backoff has a slight issue in the SR203 for VDSL2 that needs addressing for that line had better upstream speed additionally and that will impact the downstream when the upstream power is higher than needed?

I am looking at sky broadband and can only receive the essential package where my next door neighbour can get the super fast package, I have been with sky for 15 years and would love an answer why this is. 

[mae-3]

@Stephen+Chi 

You be better opening your own thread on that topic, but basically its either a line length issue or DSLAM cabinet is full.

[Stephen+Chi]

That does not say much for sky when they cant supply the goods to loyal customers.

[mae-3]

@Stephen+Chi 

It's not Sky's infrastructure it's BT Openreach's and that is the end of the topic on this thread, off-topic.

[Chrisee]

@Stephen+Chi if Openreach cannot supply Sky with a connection on your line then Sky cannot sell you a service. Nothing to do with loyalty. There a limited number of fibre connections on each cabinet so even in if your neighbour is connected to the same cabinet, which should not be assumed, it may simply be a capacity issue.
