Cannot connect to wifi, cannot change network settings [SOLVED]

Asus EeePC.
lspci -k shows
Broadcom Corporation BCM4313 adapter is the hardware, and appears to be working. Kernel driver in use is bcma-pci-bridge
In Gnome, Wi-Fi status shows "not connected"
"Select Network" shows a list of available APs, I click on ours which is set up as WPA2 PSK. Click Connect. Nothing happens. At all, no dialog for password, no attempt to connect seems to be processed by the computer. This happens with open networks as well (coffee shop or whatever). Click connect but nothing further happens.
From the applet I can't even seem to be able to "Turn off" the WiFi at all.
From within Wi-Fi settings in the applet, I can see a list of available access points but clicking on them does nothing. There is no available way for any user input, although I can click the toggle to turn off Wi-Fi from within there.
I can't forget networks in my history here either: click "History" and I can see a long list of previous networks. I can check box for them all and say "forget" but then they're back when I open the history again.
So it seems like my NetworkManager is just simply not working. Can't change the current state of "not connected" to anything at all.
When I attempt to connect using Wifi-menu I get:
Successfully initialized wpa_supplicant
>WPA Authentication/Association Failed {FAIL}
When I attempt to connect to any network. It never asks for password.
Gnome-Keyring is installed.
Netctl is NOT installed.
NetworkManager is installed and running according to systemctl
I've been running this Arch install on this machine for two years. This is not a new install problem. No hardware can be changed on this machine, so it's not hardware related (unless the wireless device itself crapped out).
Possibly related, I cannot shutdown the machine from within Gnome. I have to "sudo shutdown -h now" from a terminal. Seems to hibernate/sleep properly when the lid is closed though.
All of the results of searching on this indicate usually the problem is multiple network config softwares installed at the same time, like netctl and networkmanager together. Or not having a keyring manager installed That is not the case here unless it is one of those that is broken, but they don't seem to be.
I have no access to any wired connection at the moment at all, so I can't download anything to this computer at the moment. There's gotta be a way to get wifi working again, as it was just working last week. Haven't even done a pacman upgrade between when it last worked and when it stopped working.

I did mention the hardware is a Broadcom BCM4313
It may have been an issue with the Broadcom not working with iw. Not sure, as I haven't really changed things on this machine much (it's my wife's and I regularly update it but don't fuss with it much beyond "get it to work"). Like I said, the install is 2 years old, so compatibility may have even changed since I initially set it up.
I'm currently at work and without direct access to the computer in question. So I'll get those results later tonight.

Iphone4s no longer connecting to wifi and missing network settings

Earlier today I was using Wi-Fi at work then I went outside and the Wi-Fi went off. I was using the Wi-Fi on my iPhone 4s. When I came back inside it did not automatically go to the Wi-Fi I had to sign in and use the password it kept spinning and spinning and spinning it would never sign it at that time. I tried to forget the network reset the phone do all these things it never would sign into the network again I could never get back on Wi-Fi at work. Then I came home and my phone used to automatically attach to my home network so it did not and I had to use my home password and it gave the message unable to join network. So I tried to sign in manually and renew the lease but there was no renew the lease button. So then I was going to try to forget the network and start over but there was no forget the network button. So I tried to reset the network settings and that did not change anything there was still no renew the lease button nor forget this network butto I still cannot sign into my home Wi-Fi

Reboot your router by unplugging it for 30-60 seconds, then try again.

I just upgraded my iPad to ios6. Now my Epson iPrint crashes all the time. I called Epson and they had no answer...said to use AirPrint instead. But AirPrint stinks because you cannot change printer settings. Anybody know how to make iPrint work on ios6?

Anybody know how to make Epson iPrint work on ios6? Epson told me to use AirPrint, which stinks because you cannot change printer settings.

Epson needs an update to their app to support ios6. I'm sure they will in time.
Try deleting it and re download it. If that doesn't work, it's what I said above. :(

New imac 27(Intel based,bought 2013) slow wifi connection with my Verizon fios actiontec router. All other wireless devices in the house(ipad 3gen,MacBook Air ,hp laptop) have a much faster connection. Should I change router settings to G only,etc

New imac 27(Intel based,bought 2013) slow wifi connection with my Verizon fios actiontec router. All other wireless devices in the house(ipad 3gen,MacBook Air ,hp laptop) have a much faster connection. Should I change router settings to G only,switch channel from auto to maybe 6,channel width to 20mhz? Already changed security settings to WPA2. Currently router is running in mixed b and g mode.

If you have one computer running on G they will all run on G. All ROUTERS are backward compatible, in otherwords if you have a group of computers and all of them are N compatible and one or two are G They will all work but the N computers will run at N and those that are G will run at G speed not N.
It can get confusing but really it is simple. The newest is 802.11 AC and ic used with the newest Mac Computers made available in November 2013. So if you have the newest Airport Extreme that is 802.11ac and the newest computers that are AC compliant your speed will be 5 times faster than anything on the market right now.

IPHONE 5: can't receive calls & random error messages, such as "could not activate cellular data network" and "no connection - network unavailable, please connect to wifi or cellular network." This occurs even when signal strength or wifi is operational.

IPHONE 5: can't receive calls and random error messages, such as "could not activate cellular data network" and "no connection - network unavailable, please connect to wifi or cellular network." This occurs even when signal strength or wifi is operational, and it does not matter whether wifi is on or off. ATT went through the standard protocol - resetting network, resetting sim card, etc. No changes. Other phones working fine in same region with same carrier. Apple's solution is to restore software, but haven't gone there yet. Anyone successfully addressed this/these issues?

I should point out that it worked when the iPhone was set back to factory settings, but when restored with the backup, data/internet no longer works again, and I get the "Could not activate cellular data network" error message yet again.

Wifi connection ipad3 password correct but says I am unable to connect? Have reset my network settings but still cannot connect! Any help would be gratefully received thanks.

Hi. I am having problems connecting to the wifi at my caravan site. My iPad recognises the connection but when I put the password in correctly it says it cannot connect. I have reset my network settings in general but it has made no difference . Any ideas?

Some may not be applicable.
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

VPN Connection assistant (VPNUK via OpenVPN) cannot change network connection

I have an issue with using my VPN assistant via VPNUK.net.
The connection assistant will update the VPN connection with a new server IP and connection configuration based on what you select in the application.
There is no error specifically about the settings, but when trying to establish a connection im told that the connection failed. I then manually check the VPN in network connections and the new settings are not applied.
I suspect that the application does not have access to change the network settings, even if i run as administrator.
Are there any other privileges i need to set? Only a problem in windows 10.
Cheers
Mark

Hi Mark,
My name is Adam and I am with the Windows Beta Networking support team. I would recommend running procmon (click
here
for download link) when reproducing the behavior. You can then filter on the VPNUK process and scan for any status results such as Access Denied.
Do you get any error messages or warnings logged in event viewer at all?
Have you also engaged with VPNUK to see if they have seen issues with their client when installed on Windows 10 Preview?

I accidentally changed network settings and now I can't connect to internet

(I posted this on the board for OS X 10.4, but I figured my OS is irrelevant to my problem, so I thought I'd post it here for a better chance of getting help)
I accidentally changed some network settings on one of the computers on my network, and now it wont connect to the internet. All the other computers on the network work fine. I guess I need help getting things back to how they were.
I have absolutely no experience with networks, so I don't have a clue what to do. One thing I notice that might be of help is that when it's set to "Configure: Using DHCP," the section for "Router:" is blank. No address. The router address on all the other computers is 192.168.1.1. Similarly, the IP address on all the computers is some variation of 192.168.1.x, but on the problem computer it's a completely random number (as far as I can tell).
Any help would be EXTREMELY appreciated.
Thanks!

Open Network preferences on the computer, select the connection method, click on the Advanced button. Click on the TCP/IP tab and set the Configure IPv4 drop down menu to DHCP. Click on the Apply button.
BTW, you need to post your questions in the appropriate forum which would have been the appropriate Tiger forum. This is the Snow Leopard forum.

Internet connection not working: don't know how to change network settings

I have a Macbook Pro with an internet connection that normally works fine. However, in my apartment, we are provided with a cable modem that has only one ethernet cable hook-up. Since we needed atleast two ethernet connections for two computers, we bought a switch that we hooked into the cable modem to give us extra ethernet ports.
Recently, while hooking up my ethernet cord to the switch, I have not been able to connect to the internet. Network Diagnostics tells me my Built-in Ethernet is working correctly, but Network Settings are at yellow, and my ISP, Internet and Server have all failed. I have followed all instructions to check my connections, and restart the modem, switch and computer many, many times but there is no problem with any of these things. The other computer connects fine on the switch and cable modem.
Additionally, under Network in System Preferences, I am being shown that there is an IP address and Subnet mask, so I am assuming there is nothing wrong with the cord, modem or switch (which work fine on the other computer), but there is no Router number, which seems odd. If it helps narrow things down, I am also trying to connect to the internet via DHCP rather than PPPoE, which is what I normally use.
I am guessing I must have accidentally changed something to do with my network settings and it is not adapting to the cable modem any longer. Unfortunately, I do not know how to do this, nor what to change it to if I had to. My landlady knows nothing about what kind of network settings I need to connect to the internet service provider. Other than calling Time Warner Cable (who provides the cable modem with ethernet hook-up)is there anything else I can do or should be considering in order to get my internet connection working?

Office 2013 with Lexmark printer - Cannot change printer settings

I have a Lexmark x4650 and I can open the printer settings within all of the Office 2013 applications (Windows 7 64-bit). But after I change the settings to what I want, I cannot exit the printer settings dialog. If I click OK, nothing happens. If I click
Cancel, nothing happens. If I click the X in the upper right of the window, nothing happens. The only way to close the printer settings dialog is to force the Office application to close through the Windows task manager. I've tried re-installing both Office
and the Lexmark print driver/applications with no success. Has anyone else experienced this problem? Does anyone have a solution?
Thanks,
John

We need to narrow down the issue, to see if the root cause is on Office side or Printer side. Please try below steps for troubleshooting:
1. Try obtaining an updated printer driver from the printer's manufacturer. And update your PC, restart and try again.
2. Try to select another printer in Printer
drop-down list in any Office application, and try again to see if we have the same issue.
Printing is primarily controlled by settings in Microsoft Windows:
3. Please try to print a file outside the Office application, say a .pdf file to determine whether your printer setup in Windows is correct or using the Windows Printing
Troubleshooter.
Hope this can help you. Thanks.

Locked down computer (means I cannot see network settings) allows IE6 but Firefox always times out.

The tech guys have locked down the computer and I cannot see the network settings and have no access to the registry. Firefox always times out so I am forced to use IE6. How to set up Firefox to get round this?

Presumably, you're talking about your company's administrator. It probably wouldn't be wise to try and circumvent their network policy. It might get you fired even.
A better idea would be to show them how insecure IE6 is - ''it's no longer supported by Microsoft for example and exposes their network to all kinds of attacks'' - and that it's in their own interests to use a secure browser like Firefox 4.0
Maybe they'll even promote you!

Cannot change account settings anymore

When I try and view/change settings of an account I get a pop up message "An account with this name already exists. Please enter a different account name."
This only seems to have happened after the recent upgrade to 31.4.0, prior to this I have always been able to view/change the account settings.

HELP!
Have you done your homework?
Run DU, check/repair HD and permissions.
If that does not work, move following .plists to desktop; let system create new plists
try this one first:
com.apple.desktop.plist
reboot and see if this fixes it.
if not then move this one to desktop and repeat
com.apple.desktopscreensaver.rsspictures.plist

Verify: Cannot change sequence settings

So I just want to be sure that I understand this:
I cannot change the details of the sequence presets in FCE HD. Correct?
For example, I can choose the 'AIC 720p30' sequence preset, but I cannot change 30, to say 25?
If I have an existing clip (AIC codec, 1280x720 @ 25 fps) there is no way for me to bring this into FCE without the software rendering it (thus reducing the quality of the existing clip).
I just want to be sure I understand this correctly. I am very surprised that I cannot define sequence presets myself.
Thank you for any clarification you might provide.
BT

Thank you Tom - I really appreciate your response!!
I'm a software developer and I can't tell you how surprised I was when I discovered this limitation. So I decided to try to understand how these presets were defined by FCE.
It is actually very easy (if you are technically inclined) to create your own presets in FCE.
1) Find the FCE HD application in your Finder
2) Right-click on this icon and select "Show Package Contents"
3) Naviate to Contents/Resources/English.lproj/Final Cut Express Settings/Hardware Settings
Inside this directory you will find *.fcpre files that define the presets for FCE HD.
I am not going to explain how to modify these files but those among you who understand file formats should easily be able to create your own presets (it took me about 15 minutes to create a 720p25 preset).
-BT
PS: Do *NOT* attempt this if you don't know what you are doing. At an absolute minimum, make a copy of FCE before you start mucking around - if you mess something up FCE will fail to launch.

Cannot change print settings, print on foto size

When I want to print a webpages the printer (HP6380) prints in the format 10 x 15 instaed of A4. I tried changing the settings in printermenu but it did not help...

When reading your '''More system details...''' for the HPOfficejet 6300 series printer, the paper height is set to 11.0 and the width to 8.5 - '''inch''' settings for Letter size paper - not metric settings for A4 sized paper.
Where are you checking the setting for A4 paper?
{Ctrl + P} to see what is known as the "native print dialog", then check to make sure that printer is selected in the Printer - Name box at the top, and then hit the '''Properties''' button. The preferences that appear there are what Firefox uses. Settings that appear elsewhere or the "default" printer settings aren't what Firefox uses.
