Hey Andre,
I had some trouble trying to find a compatible gateway.
I bought a current one (1y ago?) and it didn’t work, so I gave it to a friend.
I was lucky and found two old China market pieces in a shop in my city (Athens, Greece) that actually worked.
I don’t remember the exact product code and I’m not home right now but I’m certain I’ve posted about it here.
I’ll look it up and let you know.
Edit:
Here’s my post on that issue.
DGNWG05LM was the EU version that didn’t work.
DGNWG02LM are the two CN versions that I still use.
By the way, all that was back in January. I don’t know what the current situation is
