No B10As on auction at the moment. Lots of B10Ds though and very cheap. Obviously on the info above I'm going to the B10A but what's the difference if you'll excuse my ignorance please?

The B10D variants use a slightly inferior chipset and have been widely reported to achieve lower sync rates (this may be the chipset, or skimping on the input filtering, or a combination of the two). I don't see any reason that they couldn't be used with the 1508 patches, given zyxels excellent open source policy (insofar as they provide a source package that makes working firmware), but most people who care about 1508 also want the highest rates too, so it has not been done yet.

I recommend the Zyxel VMG1312-B10A as it contains a BCM63168 which is 1 of Broadcom's better performing chipsets. It also has an additional noise filter not seen on the D variant. The D variant uses a budget Broadcom Chipset which syncs considerably lower for me/most others.

The 8324/8924-B10A shares this chipset and noise filter combo with the 1312-B10A.
They have Gigabit LAN ports over the 1312's 100Mb LAN ports. The 8924 also has 5Ghz AC WiFi.

Used as a pure bridge though the 100Mb LAN port isn't a bottleneck and you won't need the WiFi.

The 8x24 probably stands better.
The 1312 wall mounts much better though.
I wall mount mine right next to the master socket. The 8x24 comes with a bracket to wall mount that makes it hang out from the wall so there's space for the Ethernet cables on the back. I'm not a fan of the design.

Thank you all. The friendliness and amount of advice here is awesome.

Johnson pointed me in the direction of an 8324 on ebay on auction and I got it for a fair price. There were no 1312s on auction.

I'm delighted and so pleased you guys have been so helpful.

I'll come back with an update of how I get on when I've received it and got it up and running. I'll also get what stats I can from the TP-Link before I swap over. Is there anything specific you want me to get/look out for?

Thank you, from what you say, any of them would do for me. Working in IT, I have excellent knowledge of networking, routers, servers, you name it, but when it comes to broadband, it's not my area and I'm completely stumped. As you say, I don't need gigabit ethernet, as the modem passed straight into a Unifi USG. This then passes into a gigabit switch which passes the network around the house. Wireless is carried by 3 Unifi AP-AC Lite access points so WiFi isn't a concern on any modem/router. In terms of cosmetics, the 1312 would have been best because it's format would have allowed it to lie nicely on a 1u rack shelf. The 8324 however was less than half the price in the end.

B10A is supposed to have a high quality analog front end because if some sort of filter which is absent in the B10D. Others will know a lot more though.

I am not sure if this matters at all if you have a good quality line, or if you have VDSL2.

I have bought a load of B10As. (I have three lines.)

Analogue filter helps keep down errors I find on my line with the B10A and I think Roseway has tried the B10D and found the A better. I am on VDSL2.

I did try the VMG1312-B10D quite a long time ago, and its DSL performance was poor compared to the other Zyxel devices mentioned above, but I've never used a B10A.

There's another product from the same family which has excellent DSL performance, the VMG3925-B10B, but I don't know if it supports baby jumbo frames. I'm using one now as a full modem/router, and I'm very happy with it. It also looks better than the horrible glossy black models.

[Off topic : I rather like the glossy black of the B10A, don't know if this is included.]

RESULT!

Despite buying a Zyxel VMG8324-B10A, a VMG8924-B10A turned up. Not fussed, put on johnson's vustom firmware from 30th June and all is well. No longer am I losing traffic to failed packet fragmentation, but I'm getting some more speed.  Still syncing at 65Mbps but speedtest is 61.55/18.33, 3-4Mb faster down than before.

If there's a better command to get stats, let me know.

Code: [Select]

Thanks roseway. I've had to attach the output in 2 files as it was over 300kB and too long for a post. I don't understand any of it of course...
General opinions and consensus welcome.
