Wifi stopped working after upgrade, Asus N13

Hi,
A couple of days ago my wireless stopped working after I ran a full upgrade. I have tried to identify the problem to no avail. I attempted to use the Ralink drivers for my chipset rt3072 but those worked very poorly compared to the rt2800usb driver in the kernel and it kept freezing my system.
My relevant lsusb entry:
Bus 010 Device 005: ID 0b05:1784 ASUSTek Computer, Inc. USB-N13 802.11n Network Adapter (rev. A1) [Ralink RT3072]

I am using wicd but I have also tried with NetworkManager (I have made sure to systemctl disable the one not under test).
I tried using wireshark in monitor mode on another computer to capture the exchange for authentication. I can see my computer request authentication and I can see the router reply back. The reply is an authentication successful message, but then my computer immediately tries to authenticate again.
Any help would be appreciated.

Hi,
I have the same device and a similar issue.
Connection works but pinging the router shows extremely high ping (over 3000ms) and high packet loss, especially when the network is under load.
The connection drop randomly and wont reconnect until I manualy unplug and replug the usb device.
Downgrading the kernel fixed the problem.
Which kernel version did you downgrade to?
I also have the same device at home and I might face the same problem when I go back home next month.

Kodak ESP 3200 stopped working after upgrading to Yosemite

Kodak ESP 3200 stopped working after upgrading to Yosemite

Kodak has posted an unsupported hack that has been reported to enable printing to a Kodak printer not supported in OS X 10.10 ("Yosemite"). Perhaps it would have the same effect with some other kinds of printers that aren't supported in Yosemite. I have no information about that, one way or the other.
I have not tested the hack myself and I don't know all the possible effects. As far as I know it will not break the compatibility of printing software that is already compatible with Yosemite. It may degrade the security of the web administration interface of CUPS. That interface is not enabled by default, and will not be enabled by the procedure described here. Even if it were enabled, I know of no way it could be exploited, with or without the modification. Nevertheless, if you have enabled the web administration interface, you should disable it if you decide to follow these instructions. If you don't know what the web administration interface is, you haven't enabled it.

Office 2004 Applications Won't Work in Lion
You must have Office 2004 which is a PPC-only suite and will not work in Lion. You need to upgrade to Office 2011 - Mactopia - or you can try the freeware suite, Libre Office, that is functionally similar to Office 2007 for Windows except it works on Lion.
You may want to consider as well:
These two suites are similar to Libre Office but not as current or as well-supported:
NeoOffice
Open Office
And, then there is Apple's iWork suite:
Pages - word processing and layout
Keynote - presentation
Numbers - spreadsheet
Each can open and save Office compatible files. They may be purchased separately via the Mac App Store for $19.99 each.
(Access to the Mac App Store requires Snow Leopard 10.6.6 or higher and an Apple ID.)

Windows media player stop working after upgraded from firefox 6.02 to Firefox 7.01 yesterday.

windows media player stop working after upgraded from Firefox 6.02 to Firefox 7.01 yesterday.
the plugin for win media player is already installed and working fine in FF 6.02 before upgrade. i have Google this issue without any result so far. so i reinstalled the old version 6.02, until fix is found.
anyone has the similar issue with Firefox 7.01 in Win 7 32 bit ?

The issue was not with FF 7.01. VLC player version 1.11.1 is conflicting with windows media player when FF 7.01 tries to play media files! Which was not happening before in FF 6.02.
VLC and plugin media player need to be uninstalled first, then uninstalled FF 6.02. Install FF 7.01 and then win plugin media player again.

WIFI stopped working after I woke the computer up, now says connected to the network but not the internet, all other coputers and devices connected still with no problems, have pinged IP address from router and got the message "4 packets sent none receive

Hi,
WIFI stopped working after I woke the computer up, now says connected to the network but not the internet, all other coputers and devices connected still with no problems, have pinged IP address from router and got the message "4 packets sent none received"... Help
I have tried network diagnostics which doesnt help... The only other ting is, when I woke the computer up it said tat another device was using my IP... My wife had plugged her phone into the computer to charge etc but even when i turn wifi off on the phone there is no change... also in settings on the phone the IP address is different...

The answer to your question is - neither!
Your PC should to configured to obtain an IP address automatically, and to obtain DNS server IP addresses automatically, from the Airport Express. This is the way Windows (and Macs for that matter) are configued by default, and that is the way most people have their computers set up. If you manually configured your PC's IP address to be the same as your wife's Mac, it certainly explains why your PC is not able to access the internet.

WiFi stops working after install of latest 10.8.5 update on MacBook 5,1 third time reinstall OS X

WiFi stops working after install of latest 10.8.5 update on MacBook 5,1 third time reinstall OS.
MB used as email and surfing tool when on vacation. Worked fine for months. Installed the latest security patch (update) and WiFi quit working. Two days later (still on vacation) WiFi started working again and worked fine for the next 2 days.
Came home and formatted and reinstalled 10.8.5 and all was fine again. We are selling the MacBook and setup new user, everything worked fine.
The update came up again so I decided to install it and WiFi instantly stopped working after the restart.
Does anybody have any idea what is happening.
Thanks

Not really, although WiFi has been a longstanding problem for lots of people. I fix for some breaks others.
However, if you are trying to sell it, you need to revert it back to the OS that shipped with it. You cannot sell your copy of Mountain Lion with the Mac. It is only licensed to you.
You also need to include the system disks that came with the Mac. If it came with Leopard (10.5), and you have a Snow Leopard (10.6) disk, you can install that if you provide that disk also.

I have a similar problem, but after following your suggestion of deleting my iphone backup and then turning backup back on again, I needed to plug my phone into my computer to sync the backup. I re-tried to do an icloud backup and it again told me that "the last backup could not be completed"... since I had deleted the backup, it says the "Last backup: never". Ugh. I reconnected my iPhone 4S to my computer and iTunes so I could sync my phone and do a backup... it's still "waiting for sync to start"...
For your iCloud backup, you may have an app that is preventing the backup from succeeding. To locate which one, go to Settings>iCloud>Storage & Backup>Manage Storage, tap the name of your device under Backups, under Backup Options tap Show All Apps, then turn them all to Off (including camera roll) and try backing up again. If it succeeds, then the camera roll and/or one of your apps is preventing the backup and you'll have to located by process of elimination. Turn the camera roll On and try backing up again. If it succeeds, turn some of your apps to On and try backing up again. If it succeeds again, turn some more apps to On then try again; repeat this process until it fails. Eventually you'll be able to locate the problem app and exclude it from your backup.
If you turned iCloud backup off and try to sync to create a backup on your computer and got a "waiting for sync to start" error, it may be caused by a corrupt backup on your computer. You could try deleting your last backup by opeing iTunes and going to Preferences>Devices, clicking on your last backup and clicking Delete Backup. Then try again.

Why does the ipad 2 speaker stopped working after upgrading to ios 8

WWhy does the iPad 2 speaker stopped working after upgrading to ios 8 why plz respond

Hi A_S85,
It appears your iPhone has an issue relating to sound. The following article may help you find a solution:
If you hear no sound or distorted sound from your iPhone, iPad, or iPod touch speaker - Apple Support
Can't hear anything from the built-in speaker of your iPhone, iPad, or iPod touch? Maybe you can hear, but the sound is distorted, muffled, intermittent. Or maybe you hear static or crackling noises. If your iOS device has any of these issues, follow these steps.
Follow these steps and test the sound after each one.
Go to Settings > Sounds and drag the Ringer And Alerts slider to turn the volume up.
If you can hear sound from the speaker, then the speaker works. Continue with these steps to find the setting or switch that's affecting the sound. If you can't hear sound from the speaker, contact Apple Support.
Make sure the Ring/Silent switch is set to ring. If you can see orange, it's set to silent.
Restart your device.
Open an app that has music or sound effects. Adjust the volume with the volume buttons or the slider in Control Center.
Go to Settings > Bluetooth and turn off Bluetooth.
If there's still no sound, connect a headset. If you can hear sound through the headset, remove it and clear any dust or debris from the headset jack of your device.
If the device is in a case, make sure that the case doesn't block the speaker.
Use a brush to gently clear any debris from the speaker and Lightning connector (or 30-pin dock connector). The brush should be clean and dry and have soft bristles.
Update your device to the latest version of iOS.
If you followed these steps and still hear no sound or distorted sound, contact Apple Support.
Thank you for contributing to Apple Support Communities.
Take care,
Bobby_D

WiFi (Key) stopped working after upgrade to Windows 10

I thought I would post this on the forum for those who are having the same problem because help for this issue is few and far between compared to the number of pleas for assistance from HP owners. When I upgraded to Windows 10 on my Pavilion, the WiFi stopped working and I could not turn it on using the hot key (F12). I searched for answers and worked hours trying to solve it until I came upon the only suggestion that worked for me: I had to disable fast boot (power options, change what the buttons do, "change settings that are currently unavailable" (?!?)) , so I could get into the bios and then I went into the bios by pressing f10 during boot. Reset them to defaults. (Changed from default back to what I wanted) saved and the wifi button turned white after pressing during windows 10 boot up. EDIT: If it does not turn on right away, try turning it on through the wifi settings. I hope this can help a few, who like me, struggled endlessly for a problem that few HP mods seem to be responding to. Cheers.

Put your part number (PSKK2U-028002) in here. It will take you to a page that has 12 Windows 10-compatible downloads. Unfortunately, a WiFi driver is not one of them.
But there is this:
Your selected Toshiba PC is supported for upgrade to Windows 10, but not all of the software for the upgrade is available at this time. Additional software will be posted here when it is ready. Please check back at a later time.

Upgraded to Windows 10: Wifi Stops Working after about 20 minutes operation

Upgraded to windows 10. Everything was working fine. Then WIFI stops working. I reboot and again, things are fine then as the computer goes to sleep, WiFi stops working and won't reconnect unless I reboot. All other computers in the house using either Windows 7 or 8.1 are connecting just fine. Need some help or I'll roll back to 8.1. This is frustrating to say the least.

I have a HP pavilion X2 (10-j000na) which I have upgraded to Windows 10 and I have the same issue. Every so often the wifi signal is lost. When I go to the device manager it says there is an error with the driver for the Broadcom 802.11 abgn Wireless SDIO adapter. The only way to resolve this issue at the moment is to uninstall the driver and then re-installing it using the latest Windows 8 driver (sp68594.exe) in compatability mode for Windows 8.
But even then it is only a matter of time before the driver corrupts again and needs re-installing. We need an updated driver for Windows 10 and fast!

My wifi stopped working after a update last year and I have updated since, can this be fixe

MMy wi fi stopped working after a update early last year and I have just made do since then by using i pad at home. I was going to upgrade my phone but need to clarify if it was the upgrade that broke my wifi and can it be fixed? I have heaed of Apple replacing phones affected by this problem. Please help

If those solutions don't work your iPhone 4s has developed a hardware problem. The permanent solution is to get it replaced. I have not heard of Apple replacing long out of warranty iPhones.
You can search the internet for heating and freezing solutions that might work (at least for a while).
For example, see here: https://www.youtube.com/watch?v=nj10bz5bI6A

Keyboard shortcut command-w stopped working after upgrading to OSX 10.9.4

Dear all,
after upgrading to OSX 10.9.4 the keyboard shortcut command-w stops working after about 30 min of having the machine powered on. Interestingly, this phenomenon is not restricted to a certain app (Safari, etc.).
In system preferences > keyboard all settings have been set to "default".
Anybody else having the same issue?
Many thanks,
wolfgang

Hi folks,
just as quick documentation for possibly other error sources for the problem "shortcut command-w not working":
If problem persists close all applications (allL!). Then open one app like Safari, open several tabs and check whether command-w works.
Reason: it could happen that you've set command-w inadvertently in another app like Snagit. And when setting this the app did not tell you "listen dummy, this is a standard command, do you really want to replace a standard command with a app-specific command. Don't be surprised if it doesn't work when the app is running."
This is what happened to me. So close all apps and check whether problem persists.
reg,
wolfgang
