NetWorx version 6.2.8 not having speed test web sites listed.
After I did the NetWorx update today there are no websites in the list to check Internet speed using the Speed Meter.
In version 6.2.8 we have removed IP address logging. The reasons for that include general low popularity of this feature, disk space considerations, and most importantly it was not compatible with CPU-efficient monitoring.
This however has nothing to do with speed testing. You can still run your speed tests from the Speed Meter window, as you did before.
