NEW YORK (TheStreet) -- Shares of Aruba Networks (ARUN) are down 1.5% on Monday following the announcement that Hewlett-Packard (HPQ) - Get Report will buy the company for $3 billion in an all-cash deal. 

It's all about wireless, mobile, cloud and connectivity, TheStreet's Jim Cramer, co-manager of the Action Alerts PLUS portfolio, said on CNBC's "Mad Dash" segment. 

This deal gives Hewlett-Packard two of those segments, that being wireless and connectivity. 

Aruba Networks has proprietary technology that adds a slightly higher value to Hewlett-Packard at a time when investors have been worried about the company's non-proprietary technology in the PC industry. 

The acquisition also pits Hewlett-Packard against Cisco Systems (CSCO) - Get Report, as Aruba Networks is second only to Cisco in the enterprise Wi-Fi market.

It may seem odd that shares of Aruba Networks are down on this news, but the stock jumped over 20% last Wednesday when rumors for the deal began circling. The stock is up nearly 33% in the past five trading sessions. 

Aruba Networks will likely fall within the HP Enterprises division, once Hewlett-Packard completes the company's split later this year, explained co-host David Faber. 

"I was hoping" that IBM (IBM) - Get Report would make these types of acquisitions, in order to accelerate growth, Cramer added. 

Perhaps management is worried more about buying back stock to please shareholders like Warren Buffett, rather than making a bolder move instead, he concluded.
