Wifi problem since 10.11.2

I was able to fix this (for now).

Looking at Wifi diagnostics I noticed I had quite a bit of noise along with bad RSSI.

At the end it looks like the cause is a new USB hub 3.0 HUB I use from HooToo. Again I didn't have this issue on .2 nor Windows.

Disconnecting it from the Macbook made me connect to the Wifi Router np. :/

I have testes the MTU, after 4 days with everything working, the WiFi went dead again, and the solution still is to turn-off and on again!

Grrrrr.... so all the others possibilities solutions failed!!

I have noticed the last week (maybe a week or two after I did the update that my wifi was dropping once an hour for my laptop only...). Has worked fine for over a year (have router in the same room...). It just keeps dropping now, every 15 mins. My macbook pro is a 2014 model and still under warranty but I'm 3 hours from the nearest Mac store. I'm pretty savvy and have looked into everything, deleted the network connection, did a hard reset, updated/changed wireless settings all to no avail. My Ipad sitting next to me never disconnects though and I'm getting super frustrated. Any suggestions beyond the ordinary? It reconnects after 10 seconds but it loses the signal for a second or two and then reconnects.

hopefully these wifi issues will be solved with 10.11.3 being expected shortly. The 10.11.4 beta 1 is now seeded so I'm sure it could be any day 10.11.3 update will hit the app store.

I have MacBook Pro (Early 2015). I am also having a problem with my WiFi.

When I put my Mac on sleep at night.. in the morning it shows it is connected to the WiFi but there is not internet connectivity. Every time I need to turn off my WiFi and turn it again to get it working. I tried many networks. Since I just got it, I even tried erasing my drive and installing El Capitan again, but nothing is working. I cannot downgrade to any another OS because my Mac came with 10.11.2.

Any updates?

Turn off wifi-n if you can. You'll use wifi-g only. It's much slower, but okay for average internet connections (15-20 Mbps).

And at least, the wifi will be stable.

This problem is still annoying, though.

Its soo annoying the problem is not fixed with OSX 10.11.3, same issue in 5Ghz wifi still occurs, copy big files trough network from nas to iMac 5k stops after 2-35 GB without any reason..osx says wifi is fine but there is no data transfer possible till i reconnect the wifi.

-.-

Well, if you check the page where it shows what's included in the new update, it doesn't say anything about WiFi, so, yes, no WiFi fix for this update.

FWIW, IMHO everybody concerned should file a problem on Apple Bug Report https://bugreport.apple.com

okay thats true, there is nothing done on wifi in this update but i had the hope..

i have no error messages in console so i don't know what i should report...console only says that the shares (afp) not response, but the problem is not the shares or the nas server. OS X don't recognize that the connection is lost. (In the same time problem occurs all other devices in network have no problem)

I have to say I figured out why mine was going so slow sending to the server but receiving was fast.

I have an Asus RT-AC68U, which worked great under Yosemite. I could transfer nearly 75-100mbs per second on large files. After updating to El Capitan beta it got very slow on sending from what it was.

The problem continued on all betas and it was bad. I counted today and it took 40 seconds to send a 25mb file through the LAN. Last night I tried it on a cheaper version of the router at home and it worked fine. I thought that was strange. So I contacted ASUS and they had me reset the router to factory defaults (I had kept up on firmware upgrades) and reentered all my settings except I changed wireless network names so the MBA wouldn't try to use the same settings just in case that had something to do with it.

Right after entering just enough settings to get me connected to the server on an AC wifi I tried it out. Low and behold it worked! My speeds were faster sending now than receiving. I tested a 160mb file and it took 2.5 seconds to send. Between upgrading OS's and firmware updates something in the router needed reset.

Anyway, I just wanted to let you know that maybe resetting your wifi router (I know some of you did and it didn't help) may solve some of your issues too. It may be worth the half hour of time that it takes to do it.

As a thread's original poster just wanted to add - nothing eventually helped (even clean reinstall), so I restored back to 10.11.1 using Time Machine backup and stayed there untill 10.11.3 was released. Did an upgrade to 10.11.3 couple days ago only to find out that THE BUG IS STILL THERE!

Luckily before restoring back to 10.11.1 I've tried 10.11.4 public beta and it seems like the problem went away.

So I recommend anyone to give it a try!

I'm under 10.11.4ß and Wifi doesn't work.

I don't recommend trying the public beta 10.11.4. I tried it on my 27" iMac and it wouldn't boot when it was trying to install. I tried this twice. I'm just lucky I had Time Machine backups.

I'm having this issue too on my MBP Retina, Mid 2013. I started noticing recently with 10.11.2 and now with 10.11.3. It's not too too frequent but it seems to happen when I'm doing something internet intensive. I was thinking it was the router because I was the only one getting booted off the internet, but it seems like it's just me with the issues, not my roommates (they are on 10.10.5 and 10.11.1). I'll connect to my hotspot just fine though and have no issues, which is weird to me.

Well, this is getting ridiculous. They fixed the bug in 10.11.4 Public beta 1, but it came back in Public beta 2 и beta 3.

I even submitted a bug report with logs and everything, but was told that they aware of the problem (marked my bugreport as duplicate). So, maybe you could fix it, guys? The quality of OS X really went down to drain lately :-(
