Wifi Slow/Unresponsive since El Capitan 10.11.3

Please start up in Recovery mode. In the OS X Utilities screen, select Get Help Online. A clean copy of Safari will launch. No plugins, such as Flash, will be available. While in Recovery, you'll have no access to your saved bookmarks or passwords, so make a note of those before you begin, if they're needed for the test.

Test. After testing, restart as usual and post the results.

Hi,

In recovery mode all works but as soon as i reboot, same problems

I've stopped all software from loading when starting up and rebooted - same problem as above.

Not sure what to do now....but this is been going on since the el captain update 10.11.3

I solved the issue by uninstalling ESET anti virus - took me the whole bloody day to figure out what was going on.....

Don't just remove it from startup - just uninstall completely. ESET has been informed of this issue

Great - i've got Eset on the horn now - waiting in line. I didn't by ESET for nothing - i want to know what they're doing to fix this...

I'll let you know what they have to say, ok?

Ditto but I really want ESET so what next? Is it up to ESET or Apple to resolve this conflict?

I just spoke to ESET - they admitted that they have a problem, since december. They told me that most anti-virus software have this problem.

They told me uninstalling en reinstalling could do the trick but they can't say how long this solution will work.

They also said they're working on a solution but they can't say anything about a solution

Same issue was also chasing my tail around then went to the l' googles. Thanks for the info. Wish us small folks had SLA's and could get a refund for the time that we can't use ESET's product. Will follow the thread and hope someone updates it when we can install ESET again in a proper working order.

I'm asking for a refund and the guy told to send them email. They will respond within 24 hours.

If they decide too, no idea but it can't hurt to ask. Assuming that ESET is the cause if this problem is nog right.

This may very well be a bug by apple or a combination - so I'm not holding anyone responsible. Also, we're dealing with hard and software, this can happen.

I never ever buy ESET again. It took for me 4 hours, even ordered my FIOS router replacement. Poor job, ESET, very poor job. Eset now is busy with Ukranian cyber attack on their FaceBook page. ESET!!!! Come back home , fix our problems first.

To uninstall this "masterpiece" of software you have to download the installer here http://www.eset.com/us/support/download/home/ it took for me almost half an hour to download it since Eset blocked the access.

Thanks!

I've had the same problem, although in my case it wasn't just wifi related. I experienced the same problem when switching over to my thunderbolt ethernet adapter. After i uninstalled eset from my machine i can confirm that internet browsing works fine again.

Same with me - any browser based connection was very slow - Ethernet, thunderbolt and WiFi. Internal (NAS and Switches) and external web pages were all affected - funnily enough with the exception of the management page of my firewall !.

You don't need to download an installer.

Go to applications in finder and find ESET. Right click to "Show Package contents". Navigate to Contents -> Helpers where you will find an uninstaller.

By the way: this problem only occurs with http:// websites - https:// should be fine

ah ha.... that's why the management page of my firewall was un-affected

Yup 🙂
