Anyone know why my wifi sees 5G but won't connect?

I have an Air Port Extreme router, the new tall one. Full 2.4/5ghz Dual-Band. Of course all my Apple devices will connect and activate 5G and I see between 800mbps to 1200mbps connection speeds. However I've tried THREE different brands of Wifi AC Dual-Band devices for my Windows gaming rig and while ALL will see both the 2.4G and 5G router wifi connections, any attempt to connect to the 5G will just see it ignored and it connects to the 2.4G. Signal quality for both is 100%.
I even have the 5G set to 40mhz (channels 48-187) and it won't work. If I set up the router to split the 2.4G and 5G as two access points, the 5G won't even show up for my Windows box.
Has anyone run in to this? Is Apple up to shenanigans or am I not understanding how this works? For now my rig is on 2.4G and seeing 144mbps instead of the 800mbps I am seeing on my Apple's 5G connections.
Thanks for any help.

Are you using SMB compatible names, ie short, no spaces and pure alphanumeric.
Obviously a different name for 2.4ghz and 5ghz.
Try removing the security.. just for a test. If it won't connect with name correct and no security then there is something wrong in the computer.. but each wireless device should have a different driver.. if not make sure you download the latest driver for it.
Put the wireless security back as soon as you finish testing of course.

Vista laptop sees printer but won't connect

Vista laptop sees printers on xp server network but won't let me connect telling me "access denied" and "you do not have sufficient rights to perform this operation". What's up with this?

Yes, getting XP and Vista to share correctly is no small feat. I don't think you have a printer, printer software or driver problem. I think you have a Windows sharing problem. Have you googled for solutions in other areas? Microsoft's forums?
I was able to help someone else yesterday with this post (and some of their ingenuity as well). Maybe it will help.

C205 Internet/WIFI is on but won't connect to web.

So, my C205 was working fine yesterday. The computer is mainly used for playing video games and in the recent months had a RAM upgrade. Anyway, I was playing a game on it yesterday and after I stopped playing it, it usually causes my PC to slow down afterwards. So the typical solution for me is to reboot it and it'll be fine. Well. I rebooted it last night and it said the wifi wasn't connected to the internet but it was on.
Okay, that's weird.
I turn it off and go to bed. I wake up about 9 hours later and try it again. Wifi is on but the internet isn't connected. I tried it with local and local doesn't work either.
Tried resetting and disconnecting my router/modem, disabling and reinstall drivers, running a full virus scan (and discovering nothing) and even system restoring but it won't fix the problem.
The Lenovo PC is the only one in my household that has this problem. Every other device with internet and wifi seems to be working but the Lenovo. Is there anything I could do to fix it? The PC will be a year old two days from now. Also, this is the first time it's ever had this problem.
I'd really appreciate some help. Without the internet, the games installed on it will not work and I need this computer for school.

Hi Heosphoros,
Can you try updating by using ThinkVantage System Update? (my support site is not coming up right now, but I will post a link to the update software asap)
*edit* http://support.lenovo.com/en_US/detail.page?LegacyDocID=migr-61432
I would try uninstalling the graphics driver and reinstalling it if that update doesn't help.

Does anyone know why pages, numbers, iPhoto, keynote, etc won't open since installing lion?

It's iWork '09 which is the lastest version. iPhoto isn't working either but iMovie is, I'm so baffled and it's really frustrating. I've never had any problems at all with my mac. The crazy thing is, it's almost as though they are open but I can't see them? Is this possible? I thought it could have something to do with the multiple desktops that are available on Lion but I scrolled across and.... nothing.
I really appreciate your help. Thank you.

After doing some research I'm afraid that eventually you have to delete and reinstall iWork.
But I suggest, that you prior to such a drastic step check the following:
Have you installed the Lion upgrade to iWork 9.1?
http://www.macupdate.com/app/mac/25548/apple-iwork
Corrupted fonts also can cause this behavior, so check the fonts by opening font book, click left on user and then in the menu bar on file -> validate
That will show up any problematic font. If there are red warnings, delet the font.

Windows XP MCE sees network but won't connect

Hello
I've managed to get my AAEB working with two of my computers, one is a regular desktop which is connected through the wired outputs, this works like a charm.
The other is my personal laptop, an Acer Ferrari with Windows XP pro, this now also works perfectly on the wireless system.
Now I'm trying to get my brothers laptop to connect to our network and internetconnection through the AAEB. His laptop sees the network but when I try to connect to it it's not possible, I never even get to the part where I have to enter the password.
I'm using WPA/WPA2 for security and as stated having no problems on my own computer that's running WinXP Pro, but this one that runs WinXP MCE can't connect.
I've tryed disabling the security on the AAEB and when I do that it's possible to connect with the WinXP MCE.
Please help :'(

Thank you very much for your suggestion.
It might be me who doesn't understand fully what you mean but my problem is that I can't get the PC to connect to the wireless network.
If I plug in a ethernet cable everything works like a charm however. But I just get an error when trying to connect to the Wlan that the network might not be available anymore, eventhough I'm using it on my personal laptop at this very moment.
edit in response to your post also, I never get far enough for it to even try to recieve an IP

Airport card sees networks but won't connect.

I'm not entirely sure why.
Wired ethernet works fine, and our G4 Desktop's Airport card works fine.
Mine, however, is being a bit wonky.
I shut the computer down for the night about a week ago.
Brought it back up and got the "There was an error joining AirPort network *our SSID*".
Fine, sometimes it does that. I wait and it usually works in a few minutes.
Not this time.
We rebooted our Linksys WAP and our Cisco router, no good.
Shut the iBook down again, reseated the Airport card, fired it back up and paid close attention to the verbose boot this time.
Nothing abnormal, no errors.
Still no wireless connection.
I've tried connecting to other wireless networks around us, and we even defaulted the WAP back to out of box state (i.e. it was wide open and not passworded), but nothing. Every other wireless device in the house (G4 desktop, Dell laptop, and a Toshiba tablet) works just fine.
The computer can SEE wireless networks, but it can't connect to anything.
There have been no major system updates recently, and the only program I've installed in the past 3 MONTHS has been the World of Warcraft Burning Crusade expansion. Nothing else has changed, which is what's stumping me.
I'm starting to wonder if:
A) I'm overlooking something incredibly simple.
B) My airport extreme card is dying.

firstly, tesserax, a tremendous thank you for your help. unfortunately, i tried each step you suggested, but the problem continues.
step 1: i have tried and failed to connect to several different networks in a handful of locations (home, work, friend's house, local coffee shop, etc.).
step 2: i have disabled my own wireless encryption as well as the wireless encryption at a friends house, however, to do so i had to use their ibook, as my own either didn't list the base station in the AirPort utility (although it did list the base station in the AirPort status pull down), or it asked for a password even though the base station wasn't password protected (maybe this may add some insight into the issue?).
step 3: i have connected the computer directly to the modem using an ethernet cable and was able to go online - perhaps this means the problem is related solely to the card.
step 4: i moved the the com.apple.networkConfig.plist file and and the SystemConfiguration folder to the desktop and restarted. unfortunately, OS did NOT rebuild the files. instead, i had to go through the network diagnostics to rebuild them manually. while the files were replaced, the problem was not solved.
step 5: i reset the PRAM, but the problem still exists.
step 6: i reset the PMU, but the problem still exists.
i then tried various combinations of your suggestions, including moving the files out of the preferences folder and then reseting the PRAM and the PMU, but still nothing.
after having attempted every fix i could think of (and that was before posting to this forum) i did a full erase and install of the OS. since that's usually the cure all to whatever ails the computer, it's my assumption that the issue is a physical (hardware) one. that said, if you have any other suggestions i will be more than happy to give them a shot.
thanks again,
brad

HT4199 Every time I introduce the WPA2 passwords I can´t connect. I can only connect to open wi fi networks? Does anyone know why? Thanks

Every time I introduce the WPA2 passwords I can´t connect. I can only connect to open wi fi networks? Does anyone know why? Thanks

Some users with various Wi-Fi connection problems have reported that they were given the following instructions by Apple Support, sometimes with success. I can't vouch for this procedure myself. After completing the procedure, you'll have to recreate all your settings in the Network preference pane. Make sure you know how to do that before you begin. Taking screenshots of the preference pane may be helpful.
Step 1
Back up all data.
Triple-click the line below on this page to select it:
/Library/Preferences/SystemConfiguration
Right-click or control-click the highlighted line and select
Services ▹ Reveal
from the contextual menu.* A folder should open with an item named "SystemConfiguration" selected. Move the selected item to the Trash. You may be prompted for your administrator password.
*If you don't see the contextual menu item, copy the selected text to the Clipboard (command-C). In the Finder, select
Go ▹ Go to Folder...
from the menu bar, paste into the box that opens (command-V). You won't see what you pasted because a line break is included. Press return.
Step 2
Reset the System Management Controller

Have Mac OS X 10.5.8. Want to upgrade to safari 7.0... it will not let me! Anyone know why?
Thanks,

Of course it won't let you. You need to be running OS X Mavericks to run Safari 7.
Run "Software Update" and you'll get the latest version of Safari that's supported on Leopard. You can't use a newer version, as the OS doesn't support the APIs that newer versions of Safari require to run.

My apple tv main menu no longer displays the "movies" section, just internet, computers, and settings. Does anyone know why or how to get it back up? Recently rented a movie directly through apple tv but can't see the movies section in main menu now.

Welcome to the Apple Community.
Check the location setting for the iTunes Store is correct.
You might also try restarting the Apple TV by removing ALL the cables for 30 seconds.
Restart your router.
If you are still having problems try a restore.

Turn router off then on Try turning your wireless router off then back on.
Change or turn off wireless security You may want to try toggling the settings on your wireless router, switching from WPA to WEP or vice versa, or, as a last resort, turning wireless security off altogether. For AirPort routers, this can be accomplished with the AirPort Admin Utility. For other routers, this can usually be accomplished by accessing the router’s configuration page — open a browser and enter the address 192.168.1.1.
Reset network settings on iPad. On your iPad, open Settings, then navigate to “General” in the left-hand pane. Scroll down and tap Reset, then select “Reset Network Settings.” This will delete any stored WiFi passwords and other information, but may result in a more stable connection.
Adjust brightness upward. Oddly, a number of users have found that they can resolve this issue by simply adjusting the iPad’s brightness level upward and off the lowest setting. To do this, tap Settings, then select “Brightness & Wallpaper” from the left-hand pane. Slide the brightness bar upward, then wait 1-2 minutes and check for an improvement in signal strength. Speculation holds that a power delivery issue associated with the screen brightness affects Wi-Fi.
Change thresholds in router settings. Access your routers configuration screen (for most routers, open a browser and enter the address 192.168.1.1), then change the fragmentation threshold and the CTS/RTS threshold as described here. Some users have found success with the settings Fragmentation= 2048, RTS = 512.
Change 802.11 spec on router. Try changing your router’s wireless spec mode from B, G and N to G only or vice versa. For AirPort routers, this can be accomplished with the AirPort Admin Utility. For other routers, this can usually be accomplished by accessing the router’s configuration page — open a browser and enter the address 192.168.1.1.
Switch routers. Although a far-from-ideal solution, some users have found success with switching to a different wireless router.
Turn off “Ask to Join Networks.” To do so, tap Settings on your iPad, then select “Wi-Fi” from the left-hand pane. Slide “Ask to Join Networks” to off. Speculation holds that leaving this option on causes the iPad to constantly seek networks, resulting in some type of interference with the network to which it is connected.
Forget network then rejoin. Tap Settings on your iPad, then select Wi-Fi from the left-hand pane. Choose the network with which you are experiencing difficulty, then select “Forget this network.” Go back to the previous screen and rejoin the network.
Turn off Bluetooth. Some users report that, perhaps due to interference issues, turning off Bluetooth can boost Wi-Fi signal strength. To do so, tap Settings then tap General in the left-hand pane. Tap Bluetooth in the right-hand pane, then slide to off.

Hello i recently had a virus on my pc so i had to restart it to factory settings, while doing that i realized that my itunes got erased too so now im trying to download itunes but it wont do it correctly does anyone know why?

And then I have to save it manually. Does anyone know why this happens?

Doublechecking. Have you also tried a complete uninstall of both iTunes and all the other related software components and then a reinstall? If not, try the instructions from the following document:

A reply to similar question (Q & As , in product page Apple Store) says:
"...dissable the internal reader hardware from devices setup. Then plug the external usb superdrive and that's it." Answered by Enrique T from Lima Oct 25 2013.
If you can locate an external Apple USB 'Air" superdrive for earlier model MacBook Air, that should work. The newer one for the Air is the same as for iMac, now.
You may be able to use other brands of external USB optical drive with your older intel-based iMac, as some of them function capably. A few should also be able to see system discs or other bootable utilities on DVD.
Hopefully this helps.
Good luck & happy computing!
