I have an early-2015 MBP running 10.11.2 and have been having wifi problems on certain networks ever since buying it.
At home, my internet connection will drop every 10-15 minutes – according to the Network menu, I'm still connected to my router, but I get a timeout anytime I try to visit a page. This is not a problem that happens with any of my other devices. I've tried resetting my router and restarting my laptop, to no avail.
My router is a Cisco DPC3825.
Any ideas?
here's the exact error I get in Chrome:
This webpage is not available
DNS_PROBE_FINISHED_NO_INTERNET
I should add – despite the error – this is not a DNS problem, I've tried various DNS server combinations and none have helped.
Furthermore,my laptop doesn't want to connect to any wifi that requires browser-based authentication – e.g., ShawOpen and Starbucks networks. Not sure if this is related to the other issue but it's still irritating.

WiFi problems have been a constant problem with OS X over the past few releases. El Capitan is supposed to have fixed them, but problems still persist.
Fortuntaley, there is a fix and it invloves trashing your wireless setttings and starting again from scratch. OS X Daily has a good write up on how to accomplish this.
