I have a frustrating problem with my new laptop. On bootup the internet connections seems to link up, then drop and then reconnect. The moment I try to use an internet connection eg do a search on Google Chrome, the internet drops and won't automatically reconnect leaving me to manually connect at which point it seems to stay up. Anyone else with this problem and any solutions?

Update=we have what looks like partial success. on a clean boot up the wireless network connection seems to stay on. However I put the Laptop to sleep rather than shutting down this morning whilst I popped out for a few minutes. Upon my return I start up the machine and initially the wireless connection was working. I went to a news site when into a new story page and then after loading the page the connection dropped leaving me to manually reconnect. I rebooted the system and wireless is fine again. So the problem appears to have gone at boot up after the updates but remains if the PC goes into sleep mode. 

Issue remains coming out of sleep mode. 
Update=Resolved-I changed the Killer setting as suggested and ran the troubleshooter on the Network Adaptor. No problems detected but the Laptop connected after going into sleep mode after that.
