Sprint broadband 595U aircard disconnects

[circuitcode]

I have a laptop with wireless LAN and blue tooth keyboard/mouse. I installed Sierra Wireless 595U USB aircard with Sprint Connection Manager. I disable wireless LAN to connect 595U aircard. Connection manager connects and I link to Sprint speed test. Download speed test usually completes at around 956 Kbs/sec but Connection Manager goes to "no device" and then to "disconnected" in the middle of the speed upload test. Click on "GO" and connection manager connects and stays connected for two to five minutes and then goes back to "no device" then "disconnected" scenario.
I have disabled or turned off all firewalls and security processes without improving the Internet connect time.
Does anyone have any idea of what might be the problem?
Any suggestions appreciated.

Sound like a battery issue with it, try using the card with the charging base.
