Wifi doesn't work after sleep

I'm having an issue where my wifi will stop working after sleep. This isn't the same problem where the network had to be manually reconnected--
The "radar" will be grayed out, and I can see the networks if I click on it, but I cannot reconnect, disable wifi (make the radar the pie shape). The only thing I can do is do a hard reset holding the power button until the computer shuts off.
In fact, if I select 'Apple -> Restart,' nothing happens. I have to hold the power button down.
Any thoughts?

M3800 Developer Edition: wifi doesn't work after sleep

I have an M3800 Developer Edition (2015 model). Ubuntu is factory-installed 14.04, with hardware enablement stack installed. Recently (past 1-2 weeks) wifi doesn't work after sleep (lid closed or open doesn't matter), and only rebooting gets in back. Tried rmmod and modprobe with no success. Has anyone else seen this, and/or are you aware of any open bug(s) for this?
Relevant ouput:
lsmod when problem exists:

        Hard blocked: no
3: hci0: Bluetooth

rmmod the above, then modprobe iwlwifi. Does not fix problem, only rebooting does:

Why the wifi doesn't work after the upgrade to iOS 5?

The problem is that after the upgrade to iOS 5 the wifi doesn't work. I mean, iPad is connected to the wifi but not to the internet and also the connection on the other device doesn't work. So I had to turn off the router and then turn it on.

Try a hard reset first to see if that does any good. To do this, press and hold both the Sleep/Wake and Home buttons together long enough for the Apple logo to appear.
If no luck with that, you'll need to manually connect your iPod to your iTUnes library in recovery mode using the instructions in the Apple support document below. Doing so will allow you to bypass the passcode and restore the iPod.

Wifi doesn't work after screen replacement

My husband was gracious enough to replace the screen on my ipad 2. However, now, I can't connect to wifi unless I'm right next to the router.The antenna needs alot of signal to see any network. He verified the antenna isn't broken. Any ideas on how to fix this problem?

Some things to try first:
1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
4. Go into your router security settings and change from WEP to WPA with AES.
5. Renew IP Address: (especially if you are droping internet connection)
    •    Launch Settings app
    •    Tap on Wi-Fi
    •    Tap on the blue arrow of the Wi-Fi network that you connect to from the list
    •    In the window that opens, tap on the Renew Lease button

WiFi doesn't work after repair

Hi,
Today I received my iMac 27" back from repair. It had the screen and the optical drive replaced since both were defect.
According to the papers, nothing else has been replaced, but WiFi doesn't work now. I can't connect to my own network (Time Capsule), and only very few networks show up in the list -- quite often, mine is not there, and sometimes there are none at all. Checking with a laptop right next to the iMac, I can see plenty of networks (and my own network works fine).
Could the Apple guys accidentally have screwed up something? I thought about looking at the antenna connectors on the AirPort card (a guide is available on iFixIt), but it seems quite complicated (and I don't have the necessary screwdrivers).
Thanks,
Michael

And if it under warranty you do not want to open it up and void your warranty.
When the authorized tech installed new memory modules in my 09 Mac mini, he shorted out my wireless card and they had to order a new one and install it. I would take it back and have them figure out what is wrong.

Wifi won't work after sleep

I close my Macbook Air and put it to sleep. Then when I open it to wake it up, the wifi will not connect. The 'Fan" wifi icon shows it is searching for a connection but after a moment it stops.
This happens at work, home and school.
I have to turn the wifi off and then turn it back on to get it to work.
Any suggestions?

Bluetooth doesn't work after sleep mode wake up

Okay, so my computer goes to sleep while in Windows XP and I wake is up. I have my bluetooth mouse and keyboard hooked up to it and I try to wake them up. My mouse doesn't reconnect. I notice that my computer also says that it's not connected to my wireless network, but the my web browser and messenger still connect fine. I check my bluetooth preferences to find out that nothing is connected and when I try to reconnect it doesn't work. This never used to happen and it just recently started when I reinstalled windows this past week. The only way I could get the devices to reconnect was to reboot and even then when my computer goes back to sleep they still disconnect.
Anyone else have this problem... or better yet, an answer?

any help appreciated, this is very annoying.
I installed all latest updates to windows/bootcamp. Did not help.

HT4528 iPhone 4s' wifi doesn't work after upgrading to iOS 7

My Verizon iPhone 4s will not connect to wifi after upgrading to iOS 7. You would think Apple would have figured this problem out before releasing iOS 7 to the public. Any fixes?

After having trying everything out on the web, I found a fix that worked out. The thing to do is to deactivate your phone and then reactivate it. The way to do it is to first power off the phone. Then take out the SIM card. Then power on the phone and make an emergency call for about 5 sec. Turn the power off. Place the SIM card back into the phone. Power on the phone and plug it into the computer and to itune. Itune will then ask for your user name and password. The wifi will be working.
All you have to do then, is reinstall your saved restored file.
That's it !!

One of these may help:
1. Go to the Network and Sharing Center > Change adapter settings (in the left pane), right-click on the connection you‘re using, click Properties > Networking Tab. Now remove the tick from the IPv6 box. If it makes no difference or causes other problems
it is completely reversible by ticking the box.
2. Right-click Computer, click Properties > Device Manager (in the left pane). Expand Network Adapters > double-click the wireless adapter > Power Management Tab and make sure the check box is cleared against ‘Allow the computer to turn off this

WIFI doesn't work after IOS5...

Brand new iPad2 can't connect to wifi after the update.
I was using a 63 character passphrase WPA2 Personal AES that worked great on IOS4.
Now it tries to connect forever (small flower) without being assigned an ip address.
I'm using dd-wrt on the access point.
Any ideas guys?
Apple, my Google Nexus One is working fine and my Microsoft Windows computer.

Hello johnnyh494,
Wifi is an excellent way to supplement additional data needs. I’m always streaming internet radio, YouTube, and update apps on wifi! Not to mention, the device uses less battery power when on wifi, which is another advantage that isn’t often identified. It will be my pleasure to assist in getting your wifi connectivity working for you.
May I ask what company is the provider of the wifi service that you are using? Also, what security setting are you using? It’s traditionally recommended to use WPA2 for the security settings for home wifi networks. On the device, you are not having any data connectivity issues with 4G, correct? If not then I would recommend a hard reset on the device. Below is a link on how to do so on the Droid 4.
http://support.verizonwireless.com/clc/devices/knowledge_base.html?id=51224
As always, I recommend backing up all personal information prior to completing the hard reset. Contacts can be saved using Backup Assistant Plus. Also, contacts and calendar entries can be archived on your Gmail account. Once the reset has been completed, there is a brief tutorial on how to activate and setup the device. After completing the tutorial, please test all voice and data services as well as the wifi functionality. Please post your findings as I am eager to know the results.
Thank you…

Wifi doesn't work after 4.0.1-1 kernel update

Hi. I use 64bits archlinux, today I've updated linux from 3.18.6 to 4.0.1 and then my wifi card cannot connect to my net, network manager asks me for my password (although the password is obviously well typed). Downgrading linux to 3.18.6 solves the problem and internet connection works 'out of the box' as ever worked
I've compared dmesg and journalctl between both, 3.18.6 and 4.0.1 kernels.
dmesg-4.0.1: http://pastebin.com/ZyMvnmKm
journalctl-4.0.1: http://pastebin.com/r0r5Hd4z
dmesg-3.18.6: http://pastebin.com/1f18z9rh
journalctl-3.18.6: http://pastebin.com/HZkFASGw
I've found a warning in journalctl in 4.0.1 kernel that could be related with my problem
abr 30 14:58:51 surface NetworkManager[276]: <warn> Connection disconnected (reason 15)
However I'm really not sure what it means, any help would be very appreciated
PD: my machine is a Surface Pro and its wifi card has TONS of problems in linux, see https://bugs.archlinux.org/task/44269 and https://bugzilla.kernel.org/show_bug.cgi?id=69661 . However I believe that this problem is not related with those older bugs

David, there is no 'reason 15' in my journalctl.
However, for linux 3.19.3, there is 4-way handshake completed messages:

But during the time linux 4.0.1 kernel was active there is no 4-way handshake message, however I found the following messages in journalctl during the time linux 4.0.1 kernel was in play:

Thanks David for suggesting this!
