ER605 v2 is still supported (your model)

ER7206 v2 is still supported (beta released)

The model your pictured is the ER7206 v1 and was EOL like 2 years ago, same with the ER605 v1.  They are very different units.

  @GRL Hi

I know they are both different unit my concern for asking is that after FW 6.2 has a lot of new which feature  says that they require in gateway 6.2 FW, so I want to know will ER605 will Be getting any further updates that will help us use all these features. 
 

a few days back I had asked a question regarding speed test feature for ER605 and @MR.S told me that ER605 doesn't support the below feature as there has been no firmware update for the ER605 yet.

so I would like to should in retain my ER605 to be able to use these new features or should I update to a new getaway, and If I do upgrade which one should I buy. Thanks 

below is an explane of the feature I would like to use. 

1. Added support for on-demand Speedtest in Site > Dashboard and scheduled Speedtest in Site > Network Config > Network Settings > Internet: initiate a test on any WAN or set daily/weekly/monthly schedules; results are graphed and stored historically (requires gateway 6.2 firmware).

yes, as i said, the ER605 v2 is still supported and will be getting the update, it just hasnt been released yet.  The ER605 v2 tends to be the last one that gets a release of every new batch of firmwares.
