Oh dear, it seems as though those El Capitan WiFi issues are back again form some Mac users, as we have heard from some of our readers that the problem has been hampering their iMac devices this week.
Some of the issues we have seen before is where their wireless connection would often disconnect and then reconnect on its own. However, this week we have noticed that when some users try to visit websites the page would just hang. The only solution for them is to right click on the WiFi icon at the top right and turn off WiFi, and then turn it back on. Then just refresh those webpages and things will work once again.
It does seem strange that this issue has cropped up once again, and this is not even after performing any sort of update.
There have been similar issues in the past, and it had seemed that OS X 10.11.1 fixed them, but this does seem to be one of those persistant problems that refuses to go away.
This has now led to some users wondering when the OS X 10.11.4 release time will be, as it is needed for these WiFi issues.
Remember, only some users are having these issues snd so it is more likely to be an issue with your Mac and so there are a few things you can try to fix things.
The first is to trash your existing Wi-Fi Preferences for a fresh start. Failing that, you could create a new Wi-Fi network location by using a custom DNS. Full details on how to do these can be found on OSXDaily.
