Does TZ370 wireless support both 2.4GHz and 5GHz at same time? Or is it either 2.4GHz or 5GHz only?
Are there a lot of issues with TZ370, the forum seems to show that it locks up frequently and poor WAN throughput?
One or the other (as best I can tell). I haven't experienced lockups and WAN throughput issues you mention.
@moonraker (James Bond childhood memories) the Datashet for Gen 7 says:
All TZ integrated wireless models can support either 2.4GHz or 5GHz band. For dual-band support,
please use SonicWall's wireless access point products
Which is somewhat fuzzy, because Dual Radio would be key here to have them both, not Dual Band.
Otherwise, what @abhits said.
