Not a clue... all I know is the router is an Asus RT-AC87U and boasts about its super gaming abilities and bandwidth so would assume this would be something that would enhance the bufferbloat... but hey technology... 1 step forward and about 2 million back...

I can tell you the built in asuswrt downstream policing is junk to the point its useless, but the built in upstream QoS should at least reduce the upstream bufferbloat. My downstream policing is my own custom tc based script. In my view the downstream limit on the asus firmware can actually increase bufferbloat, so try setting the downstream speed to "higher" than your line speed leaving the buffering isp side, and only manage the upload on your QoS..

Well I found it to be a little helpful but I did have to set the bandwidth considerabley lower on downstream to take affect and even then it wasn't much.... I've since disabled it all and just let the QOS on HG612 doing its thing... it seems to do a better job!

Will look into again when I have an ISP that isn't constantly playing up... I'm having some browsing difficulties on certain websites at the moment... which is pain in the [censored] to say the least!

Hi Roberto

Hope you are well I happened to notice your post as someone had pointed out that thread to me to ask what AAISP use (WBMC Shared).

She seems to thing the default is Shared MSILs but with an option for Dedicated.

Not sure where that has come from, because I certainly dont think that If anything Shared is an extension of the Dedicated product and not the other way round

There are 2 main products WBC and WBMC.
The main difference between the two products is that WBC MSILs connect to a 3rd party supplier, whilst WBMC MSILs connect to the Core.
WBC nodes (both for WBC & WBMC) are the entry point to the 21CN backhaul.


WBMC is further split
- Dedicated for those ISPs who purchase their own bandwidth at the MSILs. As with WBC ISPs they have total control of their bandwidth and routing.
- Shared is for those ISPs who can afford to rent MSILs, so BTw buys the MSILs and shares the bandwidth between all ISPs who use shared. They dont have control of any the MSIL bandwidth or routing other than to chose where they connect to which is usually a central point in London. They purchase bandwidth in a different way to Dedicated or WBC. Termination off the Core is presented to the ISP in the form of a 'host link' at a location of their choice.

The MSILs are at the the APs - ie the InterConnects dotted around the country.
They aren't Centrals - nothing like. In fact its the Host Links that are comparable to Centrals as they both directly connect[ed] to the ISP gateway. The MSILs could be hundred of miles away from the [shared] ISP gateway.


I cant think of any simpler way to put it other than this - WBC, Dedicated WBMC & Shared WBC in a nutshell which has been up there for >6yrs.


But if it helps to take it down to a very basic level. Think of the APs as being ports in the back of a router only its a very big router with lots of ports that provide access to the 21CN backhaul.

The MSILs are like LAN cables to connect to a different switch/router. They are the cables which connect to another network - so either the Core (WBMC) or a 3rd party network (WBC).

There are hundreds/thousands of MSILs around the UK which connect to the Core both Shared & Dedicated.
Because there are so many for shared, then it is possible to get on a different one by doing a PPP disconnect. That would also depend on how many host links the ISP has, the locations, and also how the ISP has their Steering server set up. (ie if they are directing specific EU's to specific gateways).

I said on the PN forums way back in February that if PN were flat out denying there was an issue with the host links, then the other likely point would be the MSILs. Since Rev K is also noticing some of the Core entry points being hot and is also griping to BTw about some of the core node locations, it certainly does look like there could possibly be an issue with some of the shared MSILs.

Well just done a quick test as noticed some "extra" issues with my browsing...

Rather Interesting Result!

So with 24-48 hours until my migration to Zen the comparison already looks better

What a week !

And you were testing this on an idle connection?!

Something doesn't add up with that speed result and ping response.

Yes and I know it don't add up.. but checked the network to make sure and the only thing only the network with any sort of activity was Sonos system streaming Radio!

It's back to normal slow browsing now!

So not long been connected with Zen this morning and already seeing the difference in performance, also my baseline ping is around 6-7ms compared with Plusnet's 10-12ms...

Sonos Radio Streaming is working correctly again... no stutters and lags, also took 1-2 seconds to connect to the station instead of 10-25 seconds that it has the last few weeks.

Had a quick blast on some online gaming this has also now stopped lagging.

I can't compare speed to Plusnet currently as I've lost 8000Kb/s sync speed due to DLM resetting the line and losing G.INP but here is the first test!

So currently, it's what I've been looking for all the time... a stable connection and technical support was very helpful this morning, even looked for links to guides on Asus's website in case I needed them...

Soooo!, far superior to Plusnet's services, but then I suppose you pay for what you get!

No doubt you'll end up complaining about something (or multiple things) and taking them to arbitration in due course though.

Of course..... If I find something wrong that is!
