My MacBook sometimes can't connect to the internet. Chrome displays "Resolving host" but a web page doesn't appear. Safari also doesn't work. Interestingly, sometimes Google seems to work as the only web page (also auto complete in Google). After some time (or sometimes when I call "dscacheutil -flushcache") it works for a few minutes and then the issue occurs again.
Other devices always work so it has to be related to my MacBook. I'm using two DNS servers pointing to 8.8.8.8/8.8.4.4. When the issue is present Ping doesn't work (ping: cannot resolve www.google.com: Unknown host) and Lookup doesn't work too (www.google.com -> The operation couldn’t be completed. (kCFErrorDomainCFNetwork error 2.))
A few month ago I had the same issue. At the time I had to delete some files in the LaunchDeamons-folder but I can't remember which ones…
Anything I could try?
Update: If I add a second "Location" (in the Network preferences) I can simply switch to the other location and I'm back in the Internet… pretty tedious solution…

Does the issue eventually come back when creating another location? If not, this is being caused by settings.
