I'm now using one of these. You can see the results on MDWS. I stopped uploading from the HG612 at 15:28 and started uploading from the 8800NL R2 at 15:39.
I haven't tested the WiFi yet because I have little need of it, but I'll check it later. One small observation is that Billion recommend that you use this router in a vertical orientation for best WiFi performance. But it's so light in weight that if you do this the cables tend to drag it off the desk. It does have screw slots for wall mounting, so I suppose this would be the best way to orientate it vertically.
