can anyone tell me what the differences are between these two routers? the web-pages indicate them to be exactly the same, both Dual-Band Ac1300..

cheers

[Ronski]

The 8324 does not have AC WiFi. Look on the specifications page and you'll see only the 8924 has 5Ghz WiFi

[snadge]

According to their web page it does?

Edited my previous reply whilst you were typing.

[snadge]

their webpage is wrong? its title has AC/N dual-band

https://www.zyxel.com/uk/en/products_services/Wireless-N-VDSL2-VoIP-Combo-WAN-Gigabit-IAD-VMG8324-B10A/

strange...

[Ronski]

Yes it is wrong.

[snadge]

you wouldnt happen to have the ZyXEL 8924-B10A SoC specs on hand would you? 

cheers

[snadge]

I can get router specs but not what SoC it is, all i know is it is a broadcom chipset, possibly 63168 but what specs are they set at? ie. RAM, eMMC, CPU speed/core count etc

[snadge]

looking at the 63168 specs tells me the 8324 maybe 63168 but the 8924 has specs that dont coincide with it? namely AC 3x3 and USB3.0 x2 - the 63168 specs stipulate only N 2x2 wifi and USB2.0 x1..?

[siofjofj]

This is a photo of the front side of the PCB of my VMG8924-B10A. The command "cat /proc/cpuinfo" reports "system type : 963168VX" so I can confirm that the SoC is indeed a BCM63168. I also know that the VMG8324 and VMG8924 share firmware images, so are very similar.

As I understand it, the only difference between the two, as said by Ronski, is that the VMG8324 does not have 5GHz WiFi and the VMG8924 does. This is reflected by the mini-PCIe port (bottom left in the photo) not being populated on the VMG8324 (this is how the VMG8924 is able to offer AC 3x3 when the chipset does not support it, since it is provided for with separate hardware). The VMG8924 also does not feature USB3.0 (the ports are blue confusingly, but only have 4 contacts instead of the requisite 5 + 4 for USB 3.0). Both the VMG8924 and VMG8324 have two USB ports which are provided from the one offered by the BCM63168 using a USB hub chip (I believe this is the one to the left of the lower USB port in the photo, but I can't read the part number on my photo and am currently not in a position to open it to confirm).

As for more detailed specs, there are two cores (see cat /proc/cpuinfo below) and 128MB RAM (see cat /proc/meminfo below). The eMMC is a TC58NVG0S3HTA00 which is 1Gbit (so 128MB). I don't know the CPU core frequency I'm afraid.

No I haven't, but it looks like some one else has supplied the relevant info.

[snadge]

cheers guys/gals

so taking from the information above, WikiDevi mirror and on OpenWRT the spexifications for the 8924/8324 is:-

  SoC : Broadcom 63168
  CPU : Broadcom 4350v8 @ 400Mhz (dual-core)
  RAM : 128MB DDR2
  ROM : 16MB / 64MB / 128MB (unsure what the amount is for this model but all others are 16-128)
  USB : 2.0 x2
  LAN : Gigabit x4
  WAN : Gigabit x1
 WLAN : AC1300 (8924 only) / N300

[tiffy]

The VMG8924 also does not feature USB3.0 (the ports are blue confusingly, but only have 4 contacts instead of the requisite 5 + 4 for USB 3.0).

The XyXEL VMG3925-B10B modem/router has a single USB port which is also colour coded blue but I believe is USB-2 standard, indeed confusing and a bit naughty on ZyXel's part.

I've checked the USB socket on my VMG3925-B10B and can only see the 4 connector pins, having said that,  looking at my RPi 4B which has 2 X USB-2 ports and 2 adjacent USB-3 ports the pin count looks the same, can not easily see the extra 5 pins associated with USB-3 standard.

[snadge]

are their any routers (OR MODEMs) with better Broadcom chipsets that allow telnet, better features and / or similar connection speed etc..?

fancy trying a different one and see if my 16GB loss comes back UNLIKELY but i want new hardware

any recommendations guy? Im a bit behind with the times

[j0hn]

The BCM63168 still performs better than any other chipset.

The BCM63138 is newer but synced at an almost identical rate (a few kb lower).

There's nothing Broadcom based that will bring that 16Mb back.
Crosstalk can only be clawed back via Vectoring which isn't even possible on your ECI cabinet.

You're only likely to achieve a bump in sync with a Lantiq chipset and manually tweaking the SNRM down.

With FTTP coming I'd recommend not spending money on any additional xDSL hardware.
