checking our the specturm, it's looking much cleaner.

Still not so keen on the almost sinewave like motion on the connection but think @coffeebaron has outdone himself again.

66/8 on 8b is not bad! also the drop in attenuation is great!

Coffeebaron - thanks for doing a neat job of putting in the master filter, very professional. The connection stayed live on the Huawei router over the weekend (we were away so I wanted to check it didn't hang straightaway!)

I have found a beta firmware from Asus for my other router so will keep an eye on how that goes, unfortunately the Huawei seemed to drop randomly (undiagnosed, perhaps due to rogue phone/filter issues), and it had issues issuing internal IPs via powerline adaptors...

To sum up, since I joined, I've gone from 53mb (8.8dB / 2.0 dB attenuation):

to 62mb (Hio tinkering + changing to another jack):

to 66mb (changing to new master filtered jack):

Thanks to both Hio and Coffeebaron... Hopefully the guys at the Asus forums are as helpful!

Cheers

Charlie

hio77:

can't that ETP simply be replaced with a... reasonable one?

No, its a multi line feeder to the units, so would need Chorus to install a more modern multi dwelling ETP. NB: picture was of course before I finished securing cables and filter etc. :)

Feel like your Asus? modem there is slightly miss reporting attenuation FYI.

once ddDLM hits you, i'll be very interested to see how you line goes!

i suspect jumping to a good 80/30 would not be impossible..

Thanks Hio. It's a beta firmware so perhaps the stat's aren't accurate!

Is there a max on the Spark VDSL package - for some reason I had 70 as a maximum...

Max depends on linecard, Broadcom linecards will do 100/50.. Ikanos will do 70/30.

For reference double checking graphs, your on a broadcom linecard.

Quite close to cabinet, so certainly potential for a bit more speed once DLM & ddDLM have some time to adjust.

Reason i put it down to ddDLM is attenuation wise its not quite 17a. But should be..

With ddDLM doing 17a via diagnostics this would be a perfect candidate

A likely story. I am sure you just zip-tied the master filter onto one of the terminals and then left the ETP slightly open so a bit of water can get in.

Toteslegit bro.. toteslegit.

Line test results are in, looking very clean indeed! next to no errors there too :)

I must complain, there is a bit of variance around bin 594, guess you might have to go back out @coffeebaron :P

I must have not turned that screw that extra 1/8th turn, sorry about that :)

After having solid internet since the filter install, it dropped again this morning (same issue with DSL up, but can't keep a ppp session going). Going to pursue the modem firmware side of things now...

On the plus side, we're up to 70/28 speed wise. @Hio77 you mentioned that I was on a broadcom card and should be capable of 100 downstream - does this mean it should keep adjusting upwards? It shows a max speed of 111mb on the router.

Hio - one more question - there's a router setting for VDSL Profile (30a/17a/12a/8a) - what should it be set to? God knows if it has any impact - it appears to get this automatically, it's moved from 8b to 17a as you can see on the logs (was this your doing?)

I did some more digging online, and I've reset the lcp echo interval to 60 (I believe it's 0 by default) - it seems to be maintaining the PPP session, but who knows for how long.

You appear to be on a ikanos. I may have been mistaken.

Put simply your maxing the 70/30 limits now
