internet connection dropped

[fivealive]

so i was reading a news article on the steam client (related to skyrim at that)

and all of a sudden steam said no connection i look over at my wireless indicator by the clock and it shows no connection but that its trying to reconnect

so i go check the modem thinking maybe it reset since its done that a few times and no it didnt reset it was still running so i check the event viewer and this is what i found

The TCP/IP NetBIOS Helper service was successfully sent a stop control.

The reason specified was: 0x40030011 [Operating System: Network Connectivity (Planned)]

and

Name resolution for the name _ldap._tcp.dc._msdcs.phub.net.cable.rogers.com timed out after none of the configured DNS servers responded.

any idea what could cause this and what these events mean and thsi is the first time iv ever had this issue and is it something i shoudl worry bout

and also of note iv gone thru the event viewer

and this was allso there
