So I purchased a Vigor 130 recently with the intention of replacing my BT HH5B with a three device setup; the Vigor 130, an EdgeRouter and a Ubiquiti UniFi AP (and a computer running the UniFi Controller software).

It all went well, but in just over 2 days, the sync speed dropped from pretty much full speed to 73999. My IP profile was lowered to 71.55 Mbps (cab is a Huawei).

That was just after a restart (the second set of stats). Before the restart, the 'Xdsl Link Times' field was showing 8 suggesting that the device reset the VDSL connection 8 times in a 2 days period. Whatever it was, DLM lowered my IP profile.

Unplugged it all, plugged the HH5B back in. Unfortunately, despite it being online for over 13.5 days, it is stuck at 74000 and refuses to go back up to 79999 (which I got consistently for 4 years).

Should I restart the HH5B to force a resync or just leave it alone for a few more days? I want my old speed back! Thanks

Welcome to the Kitz forum. 

I doubt that a resynchronisation event will achieve any positive effect . . . It might induce the DLM to take (what it thinks to be) even more "corrective action". I would advise leaving the HH5B alone and just use the circuit. If you must monitor the statistics, just do so at the same time each day.

In all seriousness, would you have noticed the difference in actual synchronisation speed from normal usage of the circuit?

Fair point. I'll leave it well alone for a few more days (weeks?). Why is the damn DLM thing so touchy?

Not under normal usage, no. I still get sub 10 ms pings and the line works absolutely fine. But that's not the point - I want the speed that I know my line is capable of achieving

[gt94sss2]

I think the Vigor 130 has a Laniq chipset - unlike the HH5B and the Huawei cabinet which both have Broadcom. There is a theory that it's beneficial to match chipsets for better performance.

Yes, been reading up on these very forums. I'm on the lookout for a Billion or ZyXel router I can run in bridge mode

If only we knew.

Acknowledged and understood.

I am fairly certain (> 99%) that is correct . . . but let's return the missing t to the name! 

Lantiq, a subsidiary of Intel.

Did you manage to get this sorted as I have the same problem

[highpriest]

Did you manage to get this sorted as I have the same problem

Nope, got rid of it, switched to a ZyXel VMG8324 and have had no problems since. I switched ISPs last year and during the migration, a reset was performed. It has since been syncing at the full speed.

Based on my experience, I would not recommend a Vigor 130 if your line is connected to a Huawei cab.

[vipermk2]

Cheers for the response, not sure what cab I have outside, I can see it from the window but it's too dark to make out, it's only 50m away so I'll look tomorrow.

I'm thinking of moving over to Zen, just need to bide my time until the years line rental runs out.

[burakkucat]

. . . not sure what cab I have outside, I can see it from the window but it's too dark to make out, it's only 50m away so I'll look tomorrow.

Just take a look at the statistics that are available from the Vigor 130. At the bottom of the examples highpriest has shown, above, there is a line which reads --

DSLAM CHIPSET VENDOR    : < BDCM >

The BDCM is an abbreviation for Broadcom and knowing the chipset vendor, we can identify the cabinet based DSLAM.

A Broadcom chipset implies a Huawei manufactured DSLAM, whilst an Infineon chipset implies an ECI manufactured DSLAM.

Sorry to hear of your woes but my experience with the Vigor 130 has been excellent - I'm also on an Huawei cab. Whilst the max attainable is a meg or two lower on the 130 versus the HG612, the 130 still syncs at the full 80/20 on my TalkTalk connection and pings are slightly lower v HG612.

Anyway I've got FTTP On Demand on order from Fluidone so in a few months time all this FTTC cab brand, modem chipset, SNR margins, DLM malarkey etc will be a thing of the past. My only dilemma on FTTP will be which router to use...Asus RT-AC5300 or Netgear R9000

That's good to know. Speeds were fine, the attainable was broadly the same as the HH5B. But it all went horribly wrong very quickly for me. Within 3 days, my line got permanently banded (74000 kbps); this is a line that synced at a solid 80/20 for, well, since they rolled out 17A many years back.

OK, I could have had a faulty unit, but others here have had similar experiences.

Wow, nice I dread to ask how much that cost

[psychopomp1]

Wow, nice I dread to ask how much that cost

FTTPoD cost me £3700 in setup (construction) charges and then £300 per month on a 3 year contract

Obviously not cheap but I see it as a worthwhile investment.

Psychopomp1 - good for you. I would love to know how you get on, not to hijack this thread though.
