Connectivity Issues

First, this may be more of an OSX issue rather than a system but I wanted to throw this out there and see if anyone has some thoughts.

System is a XPS 9350 w/ the DW1560 Wifi card. The system is used by my wife and is/was working great for a few days but didn't have much usage. I went to use the machine this morning and found that wifi; while connected to our network and receiving an IP from DHCP did not have connectivity on the local network or out to the internet. Pings results in timeout from both the XPS and from another machine - but the weird thing is that if I take the network down and then backup for a split second anywhere from 1 - 3 ICMP packets will go out then simply start to fail.

Now, last night Filezilla was put on the laptop and we had noticed it installed iDoctor along with it, my wife removed iDoctor following their instructions and went to bed. I feel like that removable may also be a key to the issue if it isn't system related. I checked and no weird DNS or proxy stuff, I flushed the routing tables and dns cache. I also tried other wifi networks\same issue.
