    I am on a college WiFi network, and my connection drops 99% more than others I know on campus, even with poor download speeds and poor connectivity in the first place.

    I have 10.10.3 installed on my 2014 rMBP. I have looked through the error logs and can't tell what they mean, but I think it has to do with some kind of authentiation check the network runs every so often (if it does).

    Here is the Terminal data

    Code:

    Why don't report it the problem with report to Apple and let them see what is wrong with it?

    Looks like it's having issues resolving the DNS server on that network. Have you tried deleting the profile from your network settings and re-connect to it?

    Change your DNS server to Google or OpenDNS & see if that sorts it.
