Apple TV doesn't show any wireless networks

Hi,
I was using ATV with my Belkin router for connecting to my home network.Recently, I got timecapsule and setup wireless network which I am able to connect to using iphone and my macbook.I had also setup ATV to connect to wireless network created using timecapsule.Recently my ATV doesnt recognise any wireless networks. There are around 20 wireless networks shown on my macbook, but ATV shows none.I tried restarting timecapsule, ATV and everything.,
Can someone please help?

micro usb to the back of the apple tv into the comptuer, open itunes, select the apple tv from the left and follow the onscreen instructions....
if apple tv is 2nd generation just use the micro usb
if the apple tv is 3nd gen you need the power cable and the micro usb cable
hope this helps

TS1453 Apple TV doesn't show up in my iTunes. I've done all the troubleshooting steps, updated all software, restarted Apple TV, wireless router and computer. Devices doesn't show up at all in my sidebar.Apple TV doesn't show up in preferences

Help. My Apple TV won't sync with my computer. I've done all the troubleshooting tips, but Apple TV doesn't show up in my Preferences under devices.
2. Reconnect Apple TV to iTunes.
Choose iTunes > Preferences (Mac) or Edit > Preferences (Windows), click Apple TV, and make sure "Look for Apple TVs" is selected.
I see no option to select "look for Apple TV's" in Preferences, and there is no device list at all in my sidebar.
3. If Firewall is on in Mac OS X (in the Sharing pane of System Preferences), make sure iTunes Music Sharing is selected.
There is no option to select iTunes Music Sharing in my System Preferences - see screenshot
I've updated all software, restarted Apple TV, my wireless router, and my computer. Both my computer and the Apple TV are connected to the same wireless network and both are operating properly. They just wont connect to each other.
Does anyone have any suggestions?

FIRSTLY: bookmark following for further reference (it describes basic setup, both to link for syncing and to stream - from any computer.)
Apple TV (1st generation): Differences between syncing and streaming" )
Now as to your problem: If you check under "Computers" in the "Settings" menu you will most likely see the name of your iTunes library Greyed out. IF that's the case, you'll basically need to re-setup your ATV., you can do so as follows (instructions are intentionally over described, but basically your disconnecting then reconnecting your ATV1. Downside (which seems to come with all methods is that you'll have to resync all your media)
**A (not ideal but effective solution)
If ATV 1 had been working but suddenly 'disappeared" from iTunes sidebar
The following solution will almost surely work to regain your ability to Sync:
QUIT iTunes
Select "Computers" from "Settings" Menu.
Select your "greyed out" iTunes library.
This will bring up a window named "Disconnect from iTunes"
You're now given the choice to Cancel, or disconnect. WITH THE WARNING that if you disconnect any content synced with iTunes, will be erased. (in fact it will be removed from your ATV but not your computer)
Assuming ALL of your media IS on your computer, Go ahead and disconnect.
Follow instructions in the Apple doc above about setting up your ATV as a paired computer.
After you ATV gen1 reappears in the sidebar. Reset all your desired syncing preferences,
Begin syncing.
All will be fine again, (at least till the next time this occurs.) I've had to do this twice this year.
ALTERNATELY:
SHARING (a QUICKER, less destructive TEMPORARY solution (if you just want to play your media now)
You CAN set your computer to Share by following instructions in the same doc under the heading:
"How to connect to a shared computer"
HOWEVER, this will not allow you to sync info.
I've read alternate solutions on this board, one involved changing the name of your iTunes Library etc... you may wish to try this first (if it applies) https://discussions.apple.com/message/17943841?ac_cid=142432#17943841
What I'd like to know: What causes this problem... I'm suspecting iTunes updates, or any iTunes database issues or crashes. Or maybe too many visitors connecting to your other Apple devices (ATV 2 for example) or heck the weather in Guatemala...

Wireless adapter not showing any available networks

I've recently discovered that my Intel Centrino Advanced-N 6235 wireless adapter in my Asus Zenbook UX32VD running Windows 7 64 bit is not working as it won't show any available networks while my phone can find plenty in the same area.
So far I've:
-Re-installed the driver. Before I did this the adapter wouldn't even show when trying to change adapter settings. When I looked at the adapter in device manager I found an error code 52 which disappeared after I re-installed the driver.
-Re-installed the client for windows networks installed for the adapter which did not make a difference.
-Temporarily turned off my AVG-free anti-virus which did not make a difference.
When looking at the adapter after clicking change adapter settings in the networks and sharing center it says it's not connected, but as stated above it doesn't show any networks to connect to.
Also, when I try to use the networks diagnostics tool I get the following error message:
Windows cannot find
'::{26EE0668-A00A-44D7-9371-BEB06...\resultPage?keywords=+Network;NetworkDiagnostics'.
Make sure you typed the name correctly, and the try again.
Any possibly solutions I've not already tried are welcome. Thanks in advance for any help.

Hi,
Locate to Services and check all services relating to wireless and network are enabled: Wireless Zero Configuration and WLAN AutoConfig, etc.
Also, make sure your NIC is working correctly from device manager.

Apple TV doesn't show up in my iTunes devices list

Hey, I tried to post this question an hour ago but apparently my crappy 2.16 GHz intel 2 core duo iMac with 3 GB, 667 MHz DDR2 SDRAM can't handle anything else while it is pointing out in iMovie '09 that none of my HD video is stable enough to take advantage of the stabilization feature.
Anyway, here's my second attempt at seeking assistance for the most pressing of the many complications I am faced with as a Mac user.
I can no longer see my Apple TV in the list of devices in iTunes on my iMac. This happened after I downloaded the most recent software update for my Apple TV, and after my step-father-in-law hooked me up with a home entertainment system. I have noted below with "CHECK!" the tasks I have performed in my attempts to maintain a love affair with Apple:
Verify that you have the latest version of iTunes installed. CHECK!
Verify that you have the latest version of Apple TV software installed. CHECK!
Verify Apple TV is powered and properly connected to your television and you can navigate the Apple TV interface. CHECK!
Verify Apple TV is properly connected to your network and the network is properly configured. When configuring Apple TV, if you do not see your wireless network, exit the selection screen by pressing the Menu button then go back in and the software will rescan. DUMB THIS ONE DOWN, APPLE. HOW DO I VERIFY APPLE TV IS PROPERLY CONNECTED TO MY NETWORK? WHY NOT SAY, "CHECK THAT APPLE TV SHOWS UP IN THE iTUNES DEVICES LIST" AS A TROUBLESHOOTING OPTION WHEN SOMEONE SAYS THAT THEIR PROBLEM IS THAT THEIR APPLE TV DOESN'T SHOW UP IN THEIR iTUNES DEVICES LIST". THAT'D BE HELPFUL.
Verify network connectivity on Apple TV by playing a movie trailer in Movies > Trailers. CHECK (BUT *** IS THAT "BIG MAN JAPAN" MOVIE TRAILER ABOUT?)
Verify that the computer you are using can access the iTunes Store. CHECK!
If you're using Apple TV in a school or office environment, make sure Apple TV is on the same network segment as your computer (check with your network administrator) or else iTunes won't see Apple TV. NOT APPLICABLE
For more information on how to properly set up your Apple TV, see the Apple TV Users Guide. UH, I BOUGHT THIS THING 1.5 YEARS AGO. DO I NEED TO REALLY GO BACK TO THAT?
Restart iTunes (Quit or Exit and then reopen iTunes). CHECK!
Reconnect Apple TV to iTunes OH THANKS. THIS IS GOOD ADVICE. *** DO YOU MEAN BY RECONNECT APPLE TV TO iTunes?
If that doesn't address the issue, then:
Reset HOW?
Restart your computer. CHECK!
Rejoin network (wireless) and/or Restart your network router ***? HOW? WHERE TO I CLICK?
Reinstall iTunes OH SNAP! I'LL DO THAT IF NOBODY HAS ANY BETTER ADVICE.
If you have Mac OS X 10.5 (Leopard), click here for information on configuring Firewall. SHOOTSKIE, I WILL NEED TO GO BACK TO THE WEBSITE TO CLICK THAT LINK.
For Mac OS X 10.4 and earlier, make sure UDP port 5353 (Bonjour) is open on your firewall. If you use Windows Firewall, follow the steps here. SHOOTSKIE, AGAIN, NEED TO GO TO WEBSITE TO CLICK LINK, BUT I AM HOOKED UP THROUGH A WIRED CONNECTION DO I STILL NEED THIS STUPID PORT STUFF?
Otherwise, if you use other firewall software or hardware, check the software documentation on how to open UDP port 5353. IT IS SO COMPLETELY, RIDICULOUSLY LAME THAT "OPEN UP UDP PORT 5353" EVEN NEEDS TO BE PART OF THE INSTRUCTIONS FOR GETTING MUSIC FROM YOUR COMPUTER ONTO YOUR TV."
If you use Windows, try disabling services and startup items that may be conflicting. UHH, WHY WOULD I EVER HAVE WINDOWS? I SPEND 10-12 HOURS A DAY ON WINDOWS AT WORK, CRASHING MAYBE ONCE EVERY FEW WEEKS. I SPEND 30-60 MINS A DAY ON MY iMAC, CRASHING 1-2 TIMES A DAY. SERIOUSLY THOUGH, WINDOWS ***** TOO. TECHNOLOGY *****. PERIOD.

Hi everyone. I am typing here on my brand new 24-inch iMac. So far it's great! However, the issue I had with the Apple TV is unrelated to the iMac itself, and I wanted to let everyone know what the solution was to my Apple TV issue.
Until early this Sunday morning when I discovered this solution, my iMac would not sync with the Apple TV. This problem began after the most recent Apple TV software update. I neglected to mention in my previous posts that my Apple TV was connected to the Internet via an Ethernet connection.
Prior to the most recent software update, I believe that my Apple TV communicated wirelessly with my iMac and via an Ethernet connection to the iTunes store. With the latest Apple TV update, the sync between the iMac and the Apple TV does not work if the Apple TV is connected to the Ethernet. My solution was as follows:
1. Disconnect the Ethernet cable from the Apple TV. Do not reconnect.
2. Restore Apple TV to the factory settings. I'm not in front of my Apple TV at the moment but navigating through the Apple TV menu to reset the settings was fairly straightforward for me.
3. After resetting the factory settings and following the instructions, I was able to see the Apple TV in my computer's iTunes, but I was stuck with the super old software version from summer '07 when I bought this thing (i.e. before you could rent movies or watch anything in HD on the Apple TV).
4. Look for the software update on the Apple TV (again, fairly intuitive by navigating the menu on your TV) and download/install the latest update.
5. If your problem was due to having your Apple TV connected to the Ethernet, I think this should do the trick! It should now show up on your computer's iMac and it should automatically start syncing your iTunes content although I did have to direct it to sync my photos.
p.s. Does anyone know how I can let Apple know that this issue exists with the latest Apple TV update? The guys at the Genius Bar at the mall I went to in Pleasanton, CA couldn't find any notes in their knowledge database about issues with the latest Apple TV software update and I think it's important that Apple knows about this.
p.s.s. I think Apple should make all of us, their consumers, more aware of how to let Apple know about these issues because this issue was so frustrating and throughout the whole troubleshooting process I felt very helpless and would have felt so much more positive about Apple if I just had a forum in which I could let Apple know I was having this issue (above and beyond this user forum through which I ended up losing much of my iTunes album artwork after following one person’s advice).
So if that forum exists, please let me know and let's brainstorm as to how to get more people like me to be aware of that forum so other people don't experience the same frustrations I have experienced.
p.s.s.s. I haven't tried reconnecting my Apple TV to the Ethernet in my home. While it will probably be slower to rent and download movies wirelessly, I don't care that much as I'm thinking I will start renting movies through Netflix instead and just use the Apple TV to watch my homemade videos on my TV.
But I am curious, why does Apple charge so frickin' much to rent a movie on the Apple TV? $4.99 for an HD movie? Everyone who has NetFlix tells me it is sooooo much cheaper and very easy to use. And to be honest, this makes me mad. Not that there is a cheaper option for renting movies/TV shows. That makes me happy. What makes me mad is that Apple charges so much to rent a movie when it doesn’t benefit them and it doesn’t benefit me. I think Apple does a lot of good things, but I think being able to rent (or even better, to subscribe to) media that you can watch (almost) instantaneously in your home is the wave of the future and still relatively new. If Apple wants to make money off of this service in the long term, they need to start by offering movies for super cheap, even taking a loss off the price they pay the production companies if they have to, because right now it's still all about adoption (i.e. getting as many people as Apple possibly can to think about renting a movie or *please please* a TV show through Apple ).
So I guess I feel like it's a lose-lose for Apple and me. Through Apple, to rent a movie (or *please please* a TV show) I will pay much more than I would with Netflix. But if Apple can walk away with an untarnished reputation after creating a special headphone input into their original iPhone device to make extra money out of nothing, then maybe they can do no wrong and we just need to keep blindly giving them our moolah? Can somebody please let me know how I could get a better job or at least a raise so that I can give Apple all of the money they are trying to squeeze out of me?
p.s.s.s.s. I am soooo sorry Apple, but the other day when I was at your store looking for the Firewire adaptor I needed to transfer files from my Firewire 400 on my old iMac to my new iMac via the Firewire 800 adaptor, I just couldn’t stomach the huge markup. I imagine you guys make a ton of money by ridiculously marking up your accessories over what one could pay elsewhere.
I know the rest of your consumers are happy to pay $50 for buying the cable in your store and I would like to apologize right now for using your in-store computers to search for the alternative pricing which I found for $19.99. I don’t believe any of your other customers saw me doing this, but if they did, please accept my sincere apologies. In the current economic environment, reputation is everything and it would be unfortunate for all of us if the Apple masses felt they were being taken advantage of.
Wow, I think I’ve got some issues with Apple that I need to work out. Anyone know a good therapist?

Mac Mini Airport Extreme - Cannot detect any wireless networks

Hello,
Last week my Mac Mini (Power PC)'s hard disk crashed. So I did a DIY replacement. I managed to re-install all the software, and installed all the latest updates.
However, for some reason, the Airport Extreme is not detecting any wireless network after the re-install.
My own wireless network router is a third-party, which has been working well for the last 2 years. My Window PC and laptop still connects to it fine.
I can see the Airport icon but it doesn't how any detected networks (and there are quite a few in my neighbourhood). I did Apple Hardware Test and it shows the Airport card to be working ok.
Any help would be wonderful!
Regards,
Leng
Mac Mini G4 Mac OS X (10.4.9)

It still may be possible that the antenna wire is not placed properly within the Mini. Here are an excerpt of the DIY instructions for installing the wireless antenna. Hope it helps...
- Make sure that the antenna cables are firmly seated in the mezzanine board.
- Pass the antenna cables through the gap at the rear of the internal frame.
- Carefully lower the internal frame down onto the motherboard. Make sure that the wires are routed to the right of the interconnect board.
- Snap the AirPort antenna onto the black plastic column next to the rear port panel.
- Tape the AirPort antenna wire to the edge of the DVD drive.

Mac Mini - Core Solo - Won't See Any Wireless network

I have a Mac Mini, first gen Intel, Core Solo, that won't see any wireless networks. However, it will see my extreme basestation, and my two airport express devices over bonjour, which makes me think that the wireless device is working.
I've reset the PMU, with no luck.
Any suggestions?

Does an Airport card show in the system profiler?
Is Airport switched on in your mini - the Airport icon in the menu bar should show at least grey bars rather than an empty white 'fan' shape?
With Airport on, when you click on the Airport icon, does it show any network?
If you click on 'Join Other Network' and type the name of the wifi network you run, what error message does the system give?
How far away from the wifi base station is the mini? What kind of structures and environment is it in?
If you move the mini to be in close proximity to the wifi base station, does it show any signal?
When you download a copy of AP Grapher (http://www.chimoosoft.com/apgrapher.html) and run it, what does it show for signals, noise etc?
How is the mini seeing any wifi devices via Bonjour - do you have it wired into your network? If so, the fact that the devices appear via bonjour doesn't mean they are transmitting wifi, nor that they are in range.
By the way, the Core Solo mini doesn't have a PMU to reset. If you used the PMU reset procedure it won't have helped, and may actually have caused problems. The correct procedure for an Intel-based mini is an SMC reset, as follows:
-From the Apple menu, choose Shut Down (or if the computer is not responding, hold the power button until it turns off).
-Unplug all cables from the computer, including the power cord and any display cables.
-Wait at least 15 seconds.
-Plug the power cord back in, *making sure the power button is not being pressed* at the time.
-Then reconnect your keyboard and mouse to the computer.
-Press the power button on the back to start up your computer.

Can't connect to any wireless networks

My macbook pro can't connect to any wireless networks outside of my home router. I've just taken it on holiday and I can't use it in any free wireless coffee shops or hotels.
Whenever i select a network it shows it's connected with black bars in the radar icon but I cant access the internet or mail. Most frustrating is it's working fine in windows when I use boot camp.
I hope someone can help

Sometimes they can be stored in your Router and/or Modem, but having them in your Mac makes it so you don't have to rely on what's in or not in other's Routers.
I don't understand DNS...
Simply put.. you type in apple.com, your Browser goes out to a DNS Server somewhere with the request to link to the number of that name, then comes back with 17.254.3.183... if you ever wonder, you could type in that 17.254.3.183 IP, if it doesn't load Apple, then you are not connected to the Internet, yet if it does, and apple.com doesn't... then it's just that nothing is looking up the addy!

Cannot detect any wireless networks on my HP ENVY TouchSmart m7 j120dx

Hello,
My laptop won't pick up any wireless networks at all - I'm having what seems like a few different problems:
1. Because the laptop won't pick up any wireless networks, I can't of course connect to the internet without using my ethernet cable.
2. When I try to turn my adapter on using the F12 key, all it does is toggle airplane mode - which isn't going to help me connect to the internet.
3. When I go to 'Network' under PC Settings, I can toggle airplane mode but the bluetooth is greyed out and can't be toggled and it doesn't even give me an option to turn back on my wifi adapter.
4. When I went into the Network and Sharing Center to enable the adapter that way under 'Change Adapter Settings', I couldn't even see the adapter listed there. All it showed was Ethernet and Hamachi because I use LogMeIn Hamachi on my computer.
By this point, I was like "Oh, great - the adapter might somehow not even be there even though it was last night," (I was online wirelessly the night before) so I went into the device manager and then expanded Network Adapters I only saw the same two Ethernet and LogMeIn adapters.
5. So next, I tried downloading the adapter - but the problem is, I have no idea what kind my laptop is supposed to have. Going to the download drivers section in the support area of the hp website, I found many options and none of them seemed to work. I also tried redownloading the Wireless Button Driver (whatever that's called) and that didn't work.
5. I even tried doing a system restore to a point of about a week ago - this also did not solve my problem because the same things were happening and the same things I tried above still are not solving the problem either.
I know countless other people have had the same problem(s) mentioned above (simple Google search told me that) with their HP ENVY Notebook PCs, so I'm hoping that someone can help me and finally solve this problem for me.
The model is HP ENVY TouchSmart m7 j120dx, the model number is E8A11UA#ABA, and my computer is running Windows 8.1 64-bit.
On another note, here's the names of the only 2 adapters that show up in my device manager list (one is for LogMeIn Hamachi);
Realtek PCIe GBE Family Controller (Ethernet)
LogMeIn Hamachi Virtual Ethernet Adapter (Hamachi)
The wireless was working fine before with Hamachi installed, so I doubt that has any significance.
If there's any other information you need that I did not mention above, feel free to ask me. I look forward to someone replying as soon as possible and being able to find a solution to this problem for me!
EDIT: One other thing I should mention is that the wifi in my location is working fine for every other device I try (phone, gaming console, other people's laptops/desktops, etc.

Hello dginther,
Welcome to the HP Forums!
I understand wireless is not working properly. If the issue just began occurring, I would perform a system restore. I want you to bring the computer back to the earliest restore point possible, in an attempt to dodge whatever caused the issue. Here is a document on how to perform a System Restore: System Restore
Next, please try the steps in this HP document: Troubleshooting Your Wireless Network and Internet Connection (Windows 8)
These steps should be enough to resolve the issue. If not, you can try a manual reinstall of the driver:
1. Go into Device Manager, then Network adapters.
2. Right-click on the wireless driver, and select "Uninstall".
3. Restart the computer. This will force the driver to reinstall itself.
Please let me know the results of your troubleshooting. Thanks!
Mario

I have just changed internet providers from BT to Virgin, and now my iTunes doesn't show any of my airport express devices.

I have just changed internet providers from BT to Virgin, and now my iTunes doesn't show any of my airport express devices. I assume that I have to reconfigure them to the the new wireless but how do I do this frmo my PC? Thanks

I would recommend that you start by performing a "factory default" reset on each of your AirPort Express base stations. Once completed, you can use the following Apple Support article to configure each base station for streaming.

Apple TV doesn't show main menu and cannot connect to iTunes store

I've been using my Apple TV almost everyday for the past week and i've had it for awhile and all of the sudden it only shows the "computer" and "settings" buttons. It looks like it's connected to the internet because it has an IP address, but it still doesn't show any of the usual buttons on the main menu. When I go to test network it says "cannot connect to itunes store," and says the same when I put in my username and password. I just entered same same username and password in my itunes with no issues so I know the username and password are correct. I've restarted my apple tv a couple of times. I tried to restore it and it says "the update was not successful. The apple tv update couldn't download at this time. Try again later." Agh! I don't know what else to do! Any suggestions are appreciated!!!! Thanks!

A reboot will reset the connection to the network, as those 2 icons are the only ones that don't require an internet connection they are the only ones that will show up in the event of such an issue.

Can no longer see any wireless networks

Hello,
I've had my macbook for just under a year now and have never had a problem seeing/connecting to any wireless networks in the past. However, over the past few days I have had issues connecting to my router. It keeps kicking me off every 15 or 20 minutes and when I try to reconnect it often gives me a timeout error. I have reset the router countless times and have even reset it to factory settings and triple checked that the firmware is up-to-date. I felt it was a router issue until this morning; it kicked me off so I reset my router and turned my airport off&on but now I cannot even see the network nor the other 10 (or so) networks that are typically viable. Since I cannot even see the wireless networks across the block anymore I seems like this has to be a computer issue (or at least the computer has to be involved to some degree).
I've tried to make an appointment at the genius bar but they are booked solid, as in they don't have any available appointments available at any time, even days in the future. Has anyone seen this problem before? Is my wireless card is on the fritz? Does anyone know of any potential software issues that could cause this?
Thanks in advance.

You can skip the Genius Bar and just call AppleCare directly.
However, a couple of suggestions:
• create a new location in your Network preferences; does the problem persist?
• create a new user and log in to that account; does the problem persist?
This one's more extreme: Do an Archive and Install, which will completely reinstall the system but preserve user accounts and data:
http://support.apple.com/kb/HT1545
If these don't help, then it may well be hardware.
Good luck!

My old PowerPC G4 no longer sees any wireless networks

My old PowerPC G4 no longer sees any wireless networks. The PowerPC and my new iMac was powered off for a week. When I powered them on, the iMac found the usual wireless networks that are seen around here but the PowerPC did not see ANY! Even though they sit next to each other!! The G4 worked fine before and was connected to the internet.
The G4 has an AirPort card in it and IS enabled. Is the problem with the card (how do I verify?) or did something get turned off on the re-boot?
BTW the AirPort card does shows up in the system info and has firmware version 9.52 but states that "wireless network not available" under the Current Wireless Network.
How do I fix this?
Please Help!

As this is an old G4, I presume you have a PCI network card.
I had a similar problem on my son's old G4. After a lot of messing around thinking it was a software problem, I discovered that the antenna was damaged and did not make a good connection to the card. I could get it to work intermittently by pushing it on. The solution was to buy a new card.
So try manipulating the antenna connection at the back of your mac to see if you can get a signal.

Cannot see any Wireless networks

After installing the latest security update for 10.3.9, I can no longer see any wireless networks. I have tried reseating my airport card along with unpluging the antenna with no luck. I have also repaired permissions and trashed the Network Interface preference file, again nada. Another suggestions would be greatly appreciated.
I have a relatively new Airport Express base station at home and I have also tried testing the connection at several wireless hotspots.

I had the same problem and that's why I ventured here for the first time after an hour's battle this morning.
My solution: restart the computer. Just when the menu has gone out of sight, you get the Keychain pop-up box informing you that the airport application has been changed and whether you wish to allow Keychain access to this new version as well. Here's the tricky part. You must react within 1 (one) second to the pop-up screen and click the "always allow"-button. Once the computer has rebooted, you should have access to your Airport network once more.
Clunky? Yes. With me, the problem was even more bizarre. I could see my trusted network in the Airport drop-down menu but even if the computer seemed to connect to it, I couldn't get an IP. Sometimes the whole upper right corner icon bar would freeze if I tried connecting.
Puzzling? You bet. I'm rather perplexed as to why I couldn't just solve this problem by removing and re-adding the Airport Keychain entry with the new version. I can only conclude: thank you, Apple, for making patches that work.
Experienced people: how do I relay my bug report to Apple?

No longer detetects any wireless network

Hi
My macbook was correctly connected to the Internet via my wireless network, and then it suddenly disconnected. It no longer detects any wireless networks (and there are quite a few usually!)
I tried to turn airport off & then back on, but no change.
I then tried to reboot my macbook, but no change either.
When it searches for wireless networks, it is very slow (sluggish).
I also booted on Windows 7 (dual boot), and it has *exactly the same* problem. Leads me to believe that it is a hardware problem, more than a software one..
The only recent change: I moved from the UK to France few days ago => new ISP & new router (but I doubt this could be the source...)
Is there anything I can do?
Replace the wireless card?
Thanks

By the sounds of it, I've been having exactly the same problem. I will be using my macbook and suddenly the airport will drop out for no reason. Sometimes I can reconnect but often I'll have to try a dozen times or more, with the connection timing out each time. I've actually set up two differently named wireless networks at home to solve this - for a while, if one dropped out, I could reconnect to the other one. Even this has now stopped working. I've tried flicking airport on and off, restarting the airport base stations, I even have one of the wireless networks configured as WDS sending to an airport base station within a couple of metres of where I normally use my machine. Nothing works. I've tried deleting ~/library/preferences com.apple.internetconfig.plist and com.appleinternetconfigpriv.plist and rebooting - for a few times that would fix it, but not any more.
The strangest thing, though, is that if I switch user accounts, I can access the wireless networks again no problem.
It's almost like there's something that needs flushing in the user account's wireless settings - a buffer, or a cache, or something. It'll generally only happen once I've been using the machine for a sustained period of time.
I'm running 10.5.8 with Wireless Card Type: AirPort Extreme (0×168C, 0×86) Wireless Card Firmware Version: 1.4.16.2 if that's of any help to anyone.
