Supported VDSL devices not through snapshots!

Hi, can anybody suggest a reliable working device that is currently available for purchase that is supported.

Snapshots do not count, have already had my fingers burnt by going down that route (2 x DM200 soft bricked with snapshots, no solution to load lede via community support)!

I have been through the lede supported device lists in which there are so many, but most if not all of these are not available for purchase because their versions have been replaced with newer version.

All I am needing is VDSL support to work in bridge mode as all the device will be doing is bridging to a Mikrotik.


You can turn your current VDSL device into a modem-only.

Turn off DHCP, wireless, and the firewall, and set the connection type to bridge or IP passthrough (whichever is available).

Then, bridge it to a router-only (LEDE-friendly) and let it do all the work.

Page 69 of the dm200 user manual explains modem only.

Hi guys, appreciate you pointing out to me how to set the router into bridge mode but I dont have any issues doing this.

The issue is that with the netgear software there seems to be a throughput issue once the line capacity is maxed out.

Example, when I use my ISP modem (which is in routed mode and which we cannot put into bridge mode) on maxing out the ISP download bandwidth a graph showing the throughput shows a straight line.

Now, when I use the Netgear modem in either routed mode or bridged mode, the graph that is showing max throughput does not flatline, it peaks, then backs off, peaks then backs off, rinse and repeat.

Its as if they have optimized it for to keep tcp constant over pure throughput, or the buffers set are two small, or they are have not enabled flowcontrol on the ethernet port.

What ever the reason, the modem is useless to me while acting like this, hence the reason for wanting to put lede onto it to see

1/ If the characteristics are the same with regards to max throughput
2/ To be able to install cake to do QOS on the interface

Hope this is clear

Except you are unable to get the DM200 working on LEDE, so that option is fading.

Yes, obviously and Netgear 'support' is also proving non helpful. So I am faced with two options, return the modems or wait out for lede snapshot that works.

On a positive note I have heard back from the person who assisted in making lede available on the DM200, so hopefully something may be done!

But why are you so bent on using OpenWrt on that DM200? As far as I understand your initial question:

... it connects to a proper router anyway. If you use the DM200 just as a modem, it will not introduce any shaping itself. You can use your Microtik to do that, like you mention with SQM/Cake if you like..

If only the DM200 worked as it should but it does not.

For all intents and purposes it looks like either there is something wrong with how the device interacts with my ISP infrastructure or there is some form of shaping undertaken by Netgear!

Also (we are going off topic here) Mikrotik cannot do what cakes does! It can do something 'similar' but is in no shape or form as good at what cake does.

My guess is the opposite: Your ISP modem, the one you can't even put into bridge mode, introduces some shaping. The DM200 does not, and in bridge mode even should not, and that's why the line is congesting.

Also, silly me, I was under the impression you had OpenWrt running on the Mikrotik.


I cant comment if there is some shaping on the ISP modem, the only thing I know is that when I use the ISP modem and saturate the download, its stays flatlined at 50mbps, the Netgear in its current state does not.

It could well be the ISP has some shaping on their modem but I highly doubnt this.

Yeah, very easy thing to do, especially if its something you yourself had done in the past, i.e. use openwrt on a mikrotik device!


Just as a clarification, judging from your other thread, snapshots have never been your problem. Your particular issues seem be caused by a newer OEM firmware instructing the OEM bootloader to do stricter checksum verifications, you would have fallen into exactly the same trap with a release image (if it would exist).


Yes, its exactly as you said, but of course, it had to be pointed out to me by someone who is more experienced than me!

At least we know where the issue lies, hopefully some sort of workaround can be found.

Who is your isp and what is the model of the isp modem.

Wouldn't a stable release imply that it works.

ISP: Cytanet (Cyprus)
Device: ZXDSL 931VII

On cytanet forum, one of the moderators has suggested placing the ZXDSL 931VII in DMZ mode. It might help to reserve a static IP for your mikrotik router first.

I know that is not the same as bridged mode but at least it's one step closer. You also would want to disable NAT on the ZXDSL 931VII.

It is not an ideal solution but worth testing.


Worth calling ISP and asking them to remotely setup up your modem to bridged mode.

Yes, your suggestions are very good, so much so ive been through all those option before


Though recently I have managed to get the ISP to allow me to bridge their modems!

However, there is no perfect solution, currently playing with cake on lede but I can only do that with the DM200 in routed mode.

Its all a fine balance of what we want to get out of the hardware!
