A software update is removable which was intended for the iPhone OS?

I have a 6 s iPhone, iOS 9.3.1 and I updated the last update but my iPhone 6s has not been good since.  Unable to connect to wifi properly.

The update was for the iPhone 6se but didn't know I shouldn't have installed.  This update may be removed from iPhone6s?

The update was for all iPhones 4 s from

I have a 6 more on 9.3.1 without problems - with regard to the WiFi

Please do the following and after each test to see if the problem is resolved - if yes, then you can omit the following steps - I tried to list them in ascending order of the effort at least on a Mac and / or an iDevice

  1. Please see recommended settings of WiFi routers and access Apple points.
  2. Check if the problem is related to a single device and if other devices connect normally-
  3. If the 2 answer is 'yes' - try to connect the device assigned to somewhere else if possible - coffee or the University
  4. Perform a forced - restart cela do not delete or purge all data and allows to solve many problems - here is how - press and hold the Off / On Home button and at the same time for about 15-20 seconds, until the Apple logo appears. Allow normal startup upward.
  5. Settings - WiFi - < network name > - Click on forget network - do a restart forced according to 3 and then add again the network
  6. If home - reboot the router by unplugging it for 60 seconds (power) and the plug and reconnect - obviously, this step can be done in a public place like a cafe or airport or University. While you're there - make sure your router is working on the latest firmware (check manufacturer's website)
  7. Settings - general - reset - Reset network settings - remember to have very practical WiFi passwords because it erases the WiFi passwords
  8. If it is a new specific net device in your home - make sure that the router gives enough DNS for all numbers which must / wants a connection - stuff like the printer, Chromecast get overlooked - ask for more details on this so not sure option
  9. Backup the device to iTunes - restore as NEW (no) - see if solves problem - if yes - restore backup
  10. An appointment of 'Genius' to an Apple Store, or select another authorized service provider.
