Q: MacBook Pro drops wifi connection...
Hi there!
My MacBook Pro is constantly dropping wifi connection, sometimes every hour, sometimes every several seconds. It is very annoying and I have no idea what the problem might be... All I can see is that my MacBook does not have assigned IP or has self-assigned IP. It is the only device in my house that has such issue, the rest work fine (several iOS and Android devices, an Acer laptop, smartTV, network attached storage and so on...) I tried using DHCP with manual address, and static address as well (I set Mac's IP to static in routers settings while using that). It helped for a few weeks but it seems like the problem is coming back. I tried deleting wifi settings and restarting both the MacBook and router... Reinstall of OS X also did not solve the problem. If you know or have any ideas what could help me I would really appreciate this.
My hardware is:
MacBook Pro 15" Retina (Mid 2012),
BTHub 4 (Type A).
Software:
OS X El Capitan v10.11.3
If you need any more informations about either hardware or software just ask. Thank you all in advance
MacBook Pro with Retina display, OS X El Capitan (10.11.3), MacBook Pro 15" Retina (Mid 2012)

Wi-Fi problems can be somewhat difficult to diagnose because there are many things that can influence the performance, but there are some tools available:
system preferences > Network > Wi-Fi > ( assist me ) > ( Diagnostics )
this will check once for gross problems. But it tends to find none when your Wi-Fi is working, and not run at all when your Wi-Fi has dropped out.
--------
Hold down the Option key while you click on the Wi-Fi Icon on the MenuBar. This displays a number of important parameters about Wi-Fi performance. it will look a little like this:
what values are you showing for PHY Mode and channel?
What RSSI or signal strength?
what transmit rate?
and very important, how many other networks do you see listed?
--------
Note also that there is an entry for Wireless Diagnostics at the end of this menu. This is NOT the same simple-minded diagnostic as in the System Preferences > Network panel. This one can be invoked from this menu for a more comprehensive look at your Wi-Fi setup. Obvious problems will be pointed out, but when completed, you can also choose to leave the window open to monitor your connection.
If you do this and go about your business, Any unusual events will cause an alert message to appear.
