[Solved] Upgraded, can't connect to internet, nl80211 not found.

So after an upgraded I enthusiastically rebooted my computer to find that now I can't connect to the internet.
My technique was that I had manually set up a wpa_supplicant configuration with wlp4s0 as my interface, and had
dhcpcd wlp4s0
run on boot.
Now however, this won't connect automatically so I tried running that command and got
wlp4s0: interface not found or invalid
So I thought okay, maybe the interface changed I'll check, so I ran
iw dev
but that simply spits out
nl80211 not found.
iwconfig gives a similar response with
lo no wireless extensions
So I thought perhaps my wireless drivers are no longer working, but when I run lspci it still picks up my card as
Network controller: Qualcomm Atheros AR93xx Wireless Network Adapter (rev 01)
so I guess not.
Netctl and wifi-menu also don't work.
What should I do?

Ah, well thank you for helping me realize that there is something horribly wrong with how I've set up /boot. I have it on a separate partition that I've apparently not been booting from.
Edit to avoid double post: So I unmounted my /boot partition. And then ran pacman -S linux to reinstall it to the /boot directory I was actually starting from, and now everything works! Thanks!

[SOLVED] Upgrading after four month (version `GLIBC_2.16' not found)

Hi all!
After some time I decide to upgrade and starting with read the manual at the site.
Firstly, I run
pacman -Syu --ignore glibc,curl
this exit successfully
Secondly,
pacman -Su
but this give me error
pacman: /lib/libc.so.6: version `GLIBC_2.16' not found (required by /usr/lib/libarchive.so.12)
pacman always return this error, so I don't install glibc manually
help me, pls
i tried to untar glibc-2.16.0-4
tar -xvf glibc-2.16.0-4-i686.pkg.tar.xz -C /
it exit with
tar: lib: Cannot create symlink to `usr/lib': File exists
tar: lib64: Cannot create symlink to `usr/lib': File exists
tar: Exiting with failure status due to previous errors
ok, glibc untared(symlinks created with my hands in ramfs mode), but nothing happens (only kdm not start, but startx works) and error while i'm trying to use pacman is same
pacman: /lib/libc.so.6: version `GLIBC_2.16' not found (required by /usr/lib/libarchive.so.12)

[SOLVED] Upgrade hard drive: Grub error 22: Partition not found

I'm trying to move to a different hard drive. I booted a live cd, created the partitions, formatted, and used "cp -a" to copy all the files over. I also updated the fstab on the new drive, and now I would expect everything to work. However, I can't get past grub.
When I boot up, I get "grub error 22: partition not found".
Here is my setup ("Arch Linux - SSD" is the entry not working):

Another note, is that grub-install takes a very long time to run after I update the menu.lst (5+ minutes), but the update does work without errors, and the new items do appear.
Any help would be appreciated, I'm wondering if I've just been looking at it too long...

I solved this by using the uuid instead of the root:
# (0) Arch Linux
title Arch Linux - SSD
uuid 128a4425-c9ae-433f-b604-5488d55a14b3
kernel /boot/vmlinuz26 root=/dev/sdb3 ro vga=775
initrd /boot/kernel26.img
Also, I got "grub-install" to run much faster by removing the fd0 from the device map.

Since upgrade, can't connect to internet on my p.c.

After recent upgrade of Firefox on my p.c., I cannot connect to the Internet although I can send and receive email in Outlook. The error message says: Firefox is configured to use a proxy server that is refusing connection.
I'm sending this from my laptop after Firefox just upgraded again. Too many upgrades.
== This happened ==
Every time Firefox opened
== Firefox upgraded to 3.5.? I think.

The problem is that Windows Vista and Windows 7 treat all IP addresses as IPv6 so your PAC file will fail unless you make changes to it or Disable IPv6 completely or BOTH.
==============================================
WINDOWS 7 IPv6 disable (though I wouldn't, because it might screw up other M$ things)
==============================================
From this web site: http://windows7themes.net/disable-ipv6-windows-7.html
# Open up the registry.
# Uncollapse [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters\]
# Next, we create a new 32-bit registry key: “DisabledComponents”: By the way, even if you are on 64-bit system you have to create a 32-bit registry key only, because it only reflects the size of the registry key. A 32-bit registry key can store a maximum value of 2,147,483,647.
# Enter: “DisabledComponents” when prompted for a name.
# Double-click the newly created registry key and copy and paste the value: ffffffff (8 F’s) [His documentation only has 6 f’s]
# Restart your PC and you are done: You just disabled IPv6 in Windows 7!
==============================================

After Mavericks upgrade, can't connect to internet

We upgraded our MacBook Pro to Mavericks, last night. Immediately afterwards, the wifi stopped connecting to the internet. It will allow us to join our WPA Personal network, but says it has a self-assigned IP address. I can't figure out why it would have connected just fine before the upgrade, but won't, now. I feel like it's probably just a setting we need to click, but have been at this for over 2 hours, now, and can't sem to find the right box to click.
Thanks,
Elizabeth

Nokia E61i can't connect to internet / Country not listed

Hi all,
My new airport express works fine with my powerbooks but my Nokia E61i does not always get internet access or see the network. I've tried changing various settings such as the channel, closed network or not, the security settings, but I can't seem to find the magic bullet.
I noticed in the wireless clients list of the airport utility that the signal level of the powerbooks is usually around -80 while the e61i is -1.
So my hunch is that it has something to do with the power level or frequency of the radio transmitter.
The Nokia was bought in the USA and the airport in Thailand. I'm wondering if changing the country setting in the wireless options to the USA would have any effect, but I can't seem to find out how to add new countries to the list. Under the wireless options it lists these countries only:
Argentina
Bangladesh
Chile
China
Korea
Nepal
Pakistan
Taiwan
I can't find any mention of what changing the country would do exactly. I assume it has to do with adhering to the various regulations of each country regarding radio transmission, which might also affect compatibility issues.
Thanks for any advice you may have.

Thanks Duane, but unfortunately the e61i still has trouble connecting.
I suspect that there are other differences besides just the channels being used between countries. Changing from one country to the next does nothing to change the list of channels available. It is always 1-11 for me.
So changing the country must change something else, otherwise why include the feature at all? My guess is there are also amperage differences and various frequency ranges within each channel to make sure the airport doesn't interfere with other transmitters in each particular region.
It would be nice to figure out how to get all the countries on my Airport Express, but have read elsewhere that people have simply exchanged their airports with Apple when moving to a new region.
Changing country non-withstanding, I am tempted to believe the problem is with the Nokia. I have noticed that the e61i likes to be the first one on the network when it does connect. I also recall it not always playing nicely with my 2wire router back in the states, causing interference for my macs, etc. Nokia calls the wifi connection wlan, which leads me to believe the compatibility issue stems from Nokia's noncompliance with the WIFI standard. Thinking that maybe Nokia got on the wifi bandwagon in a later release, I updated the device to the latest firmware (Nokia gave me the thai or lao firmware) but nothing changed.
Unfortunately neither Thailand nor Laos are listed on the airport express though it was bought from an authorized Apple reseller in Thailand. So I am back to square one.
Hmmm...

Can't connect to internet on my old g4 flat screen, network + airport ok

I installed an airport card on the g4 (dome) and connected to our wireless network, which gets a signal, (though the status is "not available"). I can't connect to internet (server not recognized), and every time I check the internet assistant app, the setting has been changed back to modem. The router is in the basement: my iMac is on the first floor and works fine, the g4 is on the second floor. Is that too far away? Do I need to update the g4? Two minis also work fine, one on first floor and one in basement. Any help appreciated.

Which iMac G4 do you have? Some iMac G4s are 802.11b while the later ones were 802.11b/g.
If your wireless network is configured for "802.11g only", the older 802.11b iMac G4 won't be able to connect.
If your wireless network is configured for "802.11n only", the iMac G4 won't be able to connect since it isn't compatible with that.

Can't connect to Internet via Airport

I have a PPPOE ISP account. Before upgrade to Lepoard, just fine. Now I can only connect to internet using cable via my router moderm. I cannot connect my wireless router.
The wireless router will appear to be connected but it said self assigned IP. If I hardcode an IP eg. 192.168.11.2 to it. The Airport status will become connected but still cannot dial into my PPPOE account. An message no PPPOE service will appear. But if I plug in the LAN cable, everything work fine. Why this happen? My wireless router work fine with my Window XP and my Mac (before upgrade to Lepoard) What configuration should I change? I am an idot to networking. I have download all patch and has tried boot to safe mode etc.
Anyone can help?

By power downs do you mean Sleep?
One thing that might work is to set the IP to Static in Network>Configure IPv4>DHCP with Manual Address.

IPhone 5 and 5c can't connect to Internet every 1 or 2 days with iOS 8.0.2

After having upgraded my iPhone 5 and my wife's iPhone 5c to iOS 8.0.2, they both can't connect to Internet every 1 or 2 days.
They can't connect via wifi neither via 3G.
If I restart the devices they start to connect again.
I tried to reset the network settings and also to restore the devices from scratch via iTunes like the Apple support suggested me, but the issue still persists.
I'm very frustrated also because I bought to my wife an iPhone telling her she wouldn't have had all the issues she used to have on a previous Samsung smartphone...
Anyone has having the same issue?

After the update, try resetting your cellular network settings on the phone. Make sure the airplane setting is correct and try shutting it on and off to see if that works.
See if that helps.
Good Luck!

Pcc can't connect to internet

Hi Chazamsk,
Welcome to the community,
This sounds like you could be behind a firewall or an antivirus program is not allowing this device to work online.
I would suggest going through your firewall settings and add PC Companion to the exceptions list.
let us know how you get on.

New problem, after pcc can install in my pc, now it can't connect to internet. It makes "not accesible". I have tried to find other solutions from other resource. But none of them works to solve my problem. Please give best solution....

Can't connect to Internet thru WRT300N

Hi all, I can't connect to the Internet thru my WRT300N after a few reboot after I have setup the Router. I use the normal WEP, Mac address filtering and SSID (VADER) broadcast setting.
When the problems happen, I can't connect to the Internet either thru Wire (Port) or Wireless. But my PCs is shown connected to my Router. Without turning off the Router and Modem, I set the Router to Factory Default and the Internet Connections came back immediately.
I have tried upgrading the Router's Firmware to the lastest and and did a setup again. The problem came back after a few reboot.
Is there anything that I have done wrong or have not did ? Please advise. Thank you all.

Thank you for the reply.
It happens to both Wired and Wireless even though both shown connected to the Router. But noticed that when it happens, the router can't communicate with the DNS Server, that's may explain why I can't connect to Internet.
Both without shutting down both Modem and Router, I reset the Router, either by hard or soft, the Internet Connection comes back immediately.

Just got new ipad2 and can't connect to internet...recognizes wifi network but won't connect

just got a new ipad2...recognizes wifi network at home, but can't connect to internet...help???

I just had a similar problem. Both the ipad 1 and ipad 2 in my household quit connecting to the network even though it seemed to recognize it. if you think it is recognizing your network, just not connecting, check to see if bluetooth is turned on. i had to turn bluetooth off and then manually enter the DNS number.
My solution also came after I re-started my network and reset all the settings on the ipad2. The DNS number then showed along with IP submet Mask and router. I used that dns number to enter into ipad1 after turning bluetooth off on it.
Totally unscientific fix that may have been more coincidental than correct but you might try it. BTW--no idea how bluetooth even got turned on to begin with.
