Hi there,
Have been following these forums for literally years but finally figured I should post and ask a question.
We've been trying to troubleshoot our FTTC connection for a while now as upstream speeds have been dropping over time and eventually realised that we're connected to a Huawei cabinet - which didn't seem to be playing nicely with our Vigor 130 modem's chipset possibly due to line length.
With the Vigor we were seeing sync of around 31.8Mb/s down; 6.2Mb/s up but swapping to an elderly Broadcom based Asus DSL-AC68U bumped sync rates back up to 38Mb/s & 8.7Mb/s. By playing around with DSL settings it seems possible to push speeds higher but at the expense of stability.
Much more interested in the upstream gains however as we upload a lot of photos (pro photographer) and run online backups etc.
Screengrab of current line stats attached - probably ought to add that this is after about 4 days of reconnecting every 7-8 hours on average!
What I'm hoping for is recommendations as to a rock solid modem for this connection.. I'm not 100% sure now if the line's stability issues are down to the DSL-AC68U generally being awful or something more fundamental as we're seeing it dropping/reconnecting every 7-8 hours along with an ever growing collection of CRC errors (10's of 1000's) while it's connected. Performance however seems fine so no idea if those are actual problems or if we need to be getting someone out to investigate some sort of physical fault (suggestions on that front more than welcome too!).
In terms of a modem, guessing it needs to be Broadcom based but is there a more current "good" option other than the original Huawei OpenReach units or old Zyxel's?
Thanks!!

There is alot of info already on this forum, you will also find out that your current modem-router is worse possible option to use with FTTC connection. If you are on long line then probably zyxel VMG1312-B10A is your best option. You can also try newest zyxel XMG3927-B50A (if I good remember) with latest broadcom chipset good wifi etc. Also pined thread with several others modem-routers and different chipsets may give you some ideas, especially if you looking for modem-router with broadcom chipset.

The Asus DSL-AC68U does not have a Broadcom DSL chip. Any apparent stability issues are probably due to the Asus.

Thanks - that was why I posted. Updated it with the Asuswrt-merlin firmware this morning which has transformed it but could definitely do with finding a better option.
Suppose I’m a little astounded that there’s not really a better option than the B10A - will see if I can track down a B50A or failing that, hit EBay.
Thanks for your input!

Thanks - would explain one heck of a lot. Bought ours a good few years back. Seems they used to sell them on the strength of “Broadcom” chipset when that’s just for WiFi.. the DSL side is Mediatek. Ah well!

The best modem for VDSL2 is a Billion 8800NL (it has best broadcom chipset for FTTC) trust me cos I used this Billion for the last 5 years. Ebay does have it for £25 inc P&P
-
The statement above does need qualifying. The original 8800NL was a champion among VDSL2 modem/routers, but it's not available now. The later R2 version employed a Broadcom budget DSL chip, and was Billion's budget model, and it wasn't rated highly at all. I don't know what version Max has.

I don't believe there is a single "best" VDSL modem. Everyone on here raves over the ZyXeL 1312-B10A - I found it WORSE than my two Huawei HG612's I've had for years and years.
There is a "best for your line" though - but we can't tell you what that is. I believe this is a case of experimentation, because every line is different.
-
What's worse is as crosstalk changes, which modem is best can change too. ???
When I first got the Zyxels they performed identical to the HG612s on my lines (though granted they don't have the filter of the 1312), but as my lines have deteriorated I found the HG612s now perform better.
Granted I'm on an ECI cabinet so my experience will be completely different to the Huawei.

I've not heard that one - very interesting.
I probably ought to give the 1312 another go just to ensure my previous results were still connect. Wonder what I will do if my 612's die....

I was surprised, I'm guessing it was some specific interference that made the difference.
I mean obviously two modems syncing at full speed, its going to be near impossible to tell the difference. But even once I started getting crosstalk I didn't notice any marked difference until recently when things took a dive even further.
-
Crosstalk is nothing to do with different modem! Make no difference! But, my cabinet does have crosstalk reduced from 108320kbps (2014) to 90260kbps (2020) with PN 80/20 with Billion and Zyzel - make no difference

I do not agree, modem sensitivity will differ so the bitloading could be drastically different between two modems. What one modem considers too noisy, another might better differentiate and be able to cope. How else would you account for a consistent difference between modems?
Granted modem firmware and even two identical modems could potentially differ, depending on component quality.

Yup, for my line zte mediatek based router gives more attainable rate and really better line stats than a broadcom tp-link router.

Sorry old post but
Is this the same
Billion 8800NL R2 Wireless VDSL
-
No, the R2 version has an inferior DSL chipset, and isn't a good performer. You need the original version, but you'll be lucky to find one.

Oh poop
Sorry about this old post
Is there any new broadcom chipset modems or routers with a good DSL and 5ghz WiFi that are still sold today

Zyxel has:
XMG3927-B50
VMG8825-B50
VMG3925-B10
All still sold today.

Thanks :)
I was looking at a Zyxel VMG4005-B50A-EU01V1F
but its out of stock and now not sure on how good or what the chipset is
I think its broadcom but as I've been advised there are bad and good ones
So is this the one to go for, I need a good chipset and fast DSL sync (fttc)
XMG3927-B50
I know the sync thing is how long is a piece of string
the old OR modem at 8 plus up and more at one time

It's worth it, currently replying to you over an xmg3927

I'm looking for a replacement for my Vigor 130, which did not play well with my new VDSL service.
Having read through many threads here, I'm getting the impression that there is no perfect option out there. Ideally, it would have:
- Broadcom chipset for use connected to a Huawei cabinet
- Support for jumbo frames without custom firmware
- Wall mountable
- Available brand new
Have I missed a product that has all this? I'm not looking to squeeze the last drop of performance out of my line, but I do need stability.

@purple52,
welcome, whats wrong with your vigor 130?

It wouldn't stay in sync; constant dropouts over two days with steadily decreasing sync rates. It had behaved perfectly for ADSL, but clearly didn't like me upgrading to VDSL2. I swapped it with a ZyXel which was stable straight away and sync rate recovered. I would like to swap it back and give it another try at some point, but I am trying to catch an intermittent line fault currently using ISP supplied equipment.
