IPhone 4s no longer seeing Wi-fi networks

I have an iPhone 4s that has been great. About 3 weeks ago my phone stopped seeing any wi-fi networks. I had been connecting to both work and home fine and my iPad 2 still does but not my iPhone. I have searched the forum but see no definitive fix.All help appreciated.

I should have added that I have done a complete restore on the phone and still have the issue.

IPhone 4S no longer seeing 5 GHz Wifi signals with iOS 7

iPhone 4S no longer sees 5 GHz wifi band.
With iOS 6 the phone saw and connected to the 5 GHz band.
I just updated to iOS 7 and the band is not even shown.
The 2.4 GHz band was always seen, and now it's the only one.
Restarting did not ameliorate the problem.
Solutions?

Try resetting network settings. General > Reset > Network Settings You will have to put your wifi password back in.

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:

If these don't help, then it may well be hardware.
Good luck!

Can no longer see ANY wifi networks

I have a 4.5 year-old PowerBook (titanium) 550... it seems my airport card is simply no longer working. No matter where I am, even when I know there is a network there and I have the password to access that network, my airport card cannot seem to see any networks. This includes networks that I control and know the settings have not changed.
This started about a month ago; for a few days I couldn't see any networks. Then, suddenly, I was able to, and connect without a problem, for about a week. Now, however, it seems the problem has returned and is permanent.
Any ideas? Could the internal antennas be messed up? Or do the airport cards sometimes just go bust?
thanks.

I have the EXACTLY same problem.
My Apple TV (3rd generation) does not attemp to find any wifi networks since two day ago. Sometimes it does find and connnects to my home wifi network, but it loses connection in a couple of minutes at the longest. When I plug in an ethernet cable, the apple TV works just fine. But when I disconnect it, same thing happens all over again. I have tested several modifications and now I am sure this is not an issue of the router or the network settings.
If anybody has a solution, please be kind to let me know. I can't even get my apple TV replaced since I'm overseas.

My iphone 4 no longer recognizes any wifi networks?

After updating my iphone to the newest operating 4.3.2 it no longer recognizes or seems to eb able to pick up any wifi networks. Have tried resetting networks, airplane mode etc etc
Thoughts?

Yep, looks like I'll be calling apple tomorrow. I downloaded an app off the Itunes store, and the app seems to have destroyed the wifi ability on both my iPhone and my Ipad2. The app is called Aplayer, and the developer website and the application support website are both MIA. Not happy at the moment, as you would think that Apple would keep updated info on the developers they put on their app store

My Mac-Pro can no longer see my local network after install

My older Mac-Pro hard drive died & I had to install Snow Leopard again from scratch. For some reason, now I can't see any of the Windows PC on my network. I CAN see the Internet (I'm on the Mac-Pro writing this) & I can see my old Mac with Tiger, but I can't seen any of the Windows XP or 7 systems. I know, they XXXX but, I still need to see them so I can taunt them & make fun of them etc...
Here's the troubleshooting part of the show:
I CAN ping them by name from Terminal & from the Network Utility.
I can NOT see them when I go to Finder > Go > Connect to Server & enter their names.
I've rebooted 4 or 5 times & installed the latest updates.
I could really use some help on this, I have about 20 computers on my network & I used to be able to see them all.

For anyone who may have this problem in the future, I thought I would post a reply myself on how I solved this problem.
The problem turned out to be my router. In the middle of the night I had an idea, so I rebooted my router & switches & now ALL the computers (even the Windoze ones) show up!

Installed XP, can no longer see MB on network

I installed boot camp on my new macbook and everything went very smoothly with that. I have internet access in both OSX and WIndows XP.
The problem is that I use my iMac and ChronoSync to sync up the two computers and to do so I have to connect them with one another via my wireless network. Before I installed XP on the MacBook both computers showed up as visible to each other automatically when they were both active, now they can't see each other for some reason. I still have the MB set to share files and nothing has changed on the iMac.
What could be causing this and how can I fix it? The only thing I can think of is if somehow there is a setting in XP that needs to be changed to allow sharing, but that doesn't make sense because I'm booted in OSX. Any ideas?

Hi,
this issue could be what your seeing. Please check to see if you have 2 Creative Cloud folders.

With the recent update of the Creative Cloud Desktop app (1.9.1.474) we unfortunately introduced a bug which causes the creation of a new Creative Cloud Files folder, and re-sync of all content. This will only occur the first time the sync application runs after the update. This has caused understandable pain and confusion, for which we truly apologise.
We have taken steps to ensure we increase our focus on quality in this area to prevent a recurrence.
Once sync has completed, you will have a “Creative Cloud Files (unknown)” folder. This is because the sync application moves your Creative Cloud Files folder to this location prior to the fresh sync. You should be free to delete this folder if you have no pending edits waiting to be sync’d to the cloud.

My Iphone 4S no longer connects to wifi networks

My smart-phone is not so smart and hasn't been since the last OS update.
I've tried to decipher where the problem is and it appears it occurs on networks where there is a "pop-up" asking you your log-in credentials (ie. airport hotspots, cable hotspots, hotels, etc.). The phone is not automatically finding and asking to join those networks. If I manually select the network in settings I get the unhelpful message that the phone is "unable to connect" to the named network
The forums suggest resetting the network but that's not an option in these cases.
I've tried resetting the phone, forgetting the network and trying again. etc. etc. but the problem persists. I thought the update to the update would fix it, but so far there is no change. I've tried manually connecting but that requires that I know the network password, protocol, etc and in most cases I don't.
It was a major problem on vacation, where I did not have cell service. The hotel had free wifi but the iphone 4S was unable to connect. (My friend's Android did, for what it's worth, and so did my ipad).
I'm one frustrated Apple consumer.

My iPhone 3GS no longer connects to home network but connects to others

I recently moved my router into another room and when I did, I messed it up big time. I fixed it and now the internet does work, BUT my iphone will not connect wirelessly to it. The network shows up on the phone, asks for a passcode and I input the pass and it it's right. It doesn't say it's wrong but it doesn't connect. This is making me mad because I can't be using my carrier's network, 200 MB can go quick when you download music or websites all the time. I'm almost over now, and I can't use my phone while home for internet until our next billing cycle.
SUM UP: Phone won't connect to wireless router anymore.

Problem solved!! I finally managed to pair the SE HCB-100 car kit speakerphone with the 3GS. I surfed the SE web site and it mentioned resetting the speakerphone. Tried it on 'one color ID' but it didn't work so I did it on all 'color IDs' and left it on reset mode when it 'accidentally' was picked up by my 3GS while searching!!! Found 'headset' and then recognised it as HCB-100. One happy guy for the holidays!!!

Adobe Acrobat 9.3.2 Update - can no longer see PCs on network (e.g. ping/offer remote assistance)

Hello - I just did the Adobe Acrobat 9.3.2 update in two different offices and the strangest thing happened while finishing 4 computers today.
I did the restart after installing the last update - 9.3.2 - and I can not connect to the computers again.
The workstations are Windows XP Pro SP3..on a SBS2003 network. The computers restart and the users can log back into the network and have no problems accessing network resources, Internet, etc. The only problem is that I can not ping the workstations from the server...I can not connect to the workstations from the server either. It's very strange how this has happened to the last 4 workstations today - when I had no problems with the other workstations yesterday.
I had the users restart the workstations several times - no luck - even shutdown/restart - no luck.
I am not in the offices to troubleshoot further in person....but I can have somebody be my "hands" onsite if need be.
Has anyone come across this before and know how to fix it - fingers crossed!!
Thanks!
Tammy

If iPhone 6+ doesn't see WiFi network after iOS 8.3 upgrade, restart router and iPhone

PROBLEM: After upgrading my iPhone 6+ to iOS 8.3, the iPhone initially would not "see" the presence of my Apple Airport WiFi network.
This was bizarre because the credentials were saved on the iPhone, the WiFi network had been continuously up, my Mac Air remained continuously logged in to the Airport WiFi, and the iPhone was able to see other WiFi networks I didn't wish to connect to such as xfinity's and the neighbor's. Just not mine.
Manually entering the network name and password had no effect.
SOLUTION: Restart the Airport WiFi router. Then restart the iPhone 6+. Now the iPhone 6+ sees and connects to the WiFi network automatically as usual.
Hope this helps some folks!

I Apologize for the long overdue reply. If your using a pc with your iPhone it is a common problem i noticed since i had iPhone 3GS, although it can occasionally happen with mac but you if backed the phone with the issue will get the same issue you had since it will be in the backup it backups software on phone as well you see.

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?

HT4942 After Creating a new document or editing an old document in Pages on my iPad I no longer see the changes in Pages on my iPhone. iCloud services are on with both devices.

After Creating a new document or editing an old document in Pages on my iPad I no longer see the changes in Pages on my iPhone. iCloud services are on with both devices.

Just thought I'd add my solution, I decided to go with WebDAV and I think it actually works better than the iTunes way, the steps are pretty much the same but avoiding the iTunes interface just makes things easier and faster.
I followed this guide but it does have a small mistake in the httpd-dav.conf file, on line 2, where it's WebServer/WebDAV">, it should be <Directory "/Library/WebServer/WebDAV">.
The tricky part is setting permissions which if wrong will give you errors when connecting with the iPad, I opted to set all to Read&Write since my home network has a hardware firewall. Another convenience was to add an alias to the webdav share on the Desktop.
I'm still expecting the call from Apple but even if they fix the iTunes I'm sticking with WebDAV, atleast until I see what's new with iOS5 and iCloud this fall which should bring true sync for documents (I'm hoping that they will offer encryption with my own keys, if not, then I'll probably keep using WebDAV).

When I open iTunes it is slow to open for one, and two when it does see my iPhone and i go to sync it this is what I get in return... The iPhone "My Name here" could not be synced because the iPhone could not be found on the network. that is a pop up box

The iPhone "My Name here" could not be synced because the iPhone could not be found on the network. that is a pop up box in middle of screen that says that it does it like every time I go to sync the phone after i do app updates. I am getting very frustrated by this can someone please help. I have made 2 other discussion topics about this and no replies on them. Please if anyone can help I ask for help. This has occurred ever since the iOS 5.1 update and the iTunes 10.6.0 and still continues with the iTunes 10.6.1 update just yesterday and perhaps even worse now. PLEASE HELP IF YOU CAN. I have looked through my network settings etc and everything looks good here on my side.
