So far, I'm delighted with the 8800NL.
I'm using it on VDSL2, and the stats are all visible on MyDSLWebStats, via BaldEagle2 & Ronski's excellent monitoring and logging software.
Same username as on here, if anyone wants to take a look.
The GUI doesn't display software version, CPU Version, or CFE version (yes, in the GUI, only CPU has "Version" instead of "version", so a slight inconsistency there.
Firmware version is displayed as "A2pv6F039g1d24m", with change detected 15/09/2014 at 02:50 (yes, I'm an insomniac).
You are welcome to any other help I can give with testing (I'm something of a tech, having set up some pretty major networks in my time) so reasonably competent at gathering debugging information.
I do try to keep good uptime, as I'm in the NTP Pool.
