Thank you for the post. So far we do not have information that i350-T2V2 is the revision for the intermittent problem of i350-T2.
I will further check on this.
Further checking, the change is to accommodate an AUX power component change which enables a decrease of in-rush current during power supply start-up, there is no change in the functionality.
With regards to the intermittent issue, you may try upgrading to latest driver https://downloadcenter.intel.com/SearchResult.aspx?lang=eng&ProdId=3395
