Yes.
Expander is using an old firmware, though most likely that is not the problem, it should still be updated as mine improved performance considerably with the latest one, mostly when using a lot of devices, but if those errors persist after updating then there are other issues, I updated mine with Windows, easier since it didn't require installing anything else, instructions are included in a txt that comes with the download.
Also a month ago you posted this in another thread:
What hardware changed between then and now? Or was that an assumption? At the time I understood you already had that combo.
