My iPhone 3G iOS 3.1.3 can't find any wifi network.

I have nothing changed. neither the iPhone nor the Network. no Update anywhere.
There are several wifi hot spots around my home, but my iPhone doesn't show any wifi.
I have wifi with my iMac, iPod and all other devices.
I can't connect to any specific wifi network.
Shut down and start up doesn't help.
Resetting all connections doesn't help.
iOS: Troubleshooting Wi-Fi networks and connections doesn't help.
Maybe it is a hardware problem, but I hope there will be a software solution to solve this problem!

I Just purchased an original iPhone and "couldn't search for wifi" kept popping up. I have the airport time capsule 2013. Tried firmware restore and everything else I could glean from the internet. Wouldn't even find any of the neighbors? Decided it was broken. Middle of night I thought?? WPA2?? First thing this morning fired up my Cisco Valet Plus router, changed the security to WEP and voila, it works like a charm. I don't think I'm going yo change my settings on the Airport Extreme, since the phone is only nostalgic. This could easily be the problem on any iPhone running 3.1.3..

After I connect with my iPhone (3GS 5.0.1) to any Ad-hoc wireless Network then walk away out of the reach of my wifi network, my iPhone can't find any wifi Network afterwards, only by turning off the iPhone completely and turning on again.

switching off wifi and on again or going into airplane mode did't help!
This problem happens only with ad-hoc wifi networks not with normal ones.
(Ad-Hoc network was created on XP Computer)

Welcome to Apple Discussions
Sorry, but the 169.x.x.x IP address is internally generated by the iPod (and iPhone) and indicates that a network has been detected but no IP address has been issued. Your friends iPhone was not connected to your ad hoc network either - it connected to the internet through the 3G network.
You should read through the Vista help screens on ad hoc networking for some insight how this works. You should be able to get some ideas there.
In the mean time, $40 or less will buy you a very capable wireless router with four Ethernet ports and will simplify your network tremendously. Having used Windows ICS for a long time, the addition of a router and a real network simplified things so much.

HT1695 Can't Find any wifi Networks after updragding to 6.0.1

My iPhone 4 can't find any wifi networks after upgrading to iOS 6.0.1 and i can't downgrade what should i do ?
I swtiched off the connection from mobile and restared the router and nothing changed!
Note: My laptop found about 7 Networks my iphone finds nothing

I have the exact same problem.
It popped up on my 8gb iPhone (2.0.1) first time when i just purchased it. The Wheel spins as if it's searching for hotspots (and there are a lot of hotspots where i live). My MacbookPro finds them without any problems.
Second time i experienced these problems, it was after i didn't have a chance to charge the phone, and i figured it was a "Low battery, disable wifi" thing. But even though i charged it fully, it still can't scan networks.
I managed to discharge the battery, until the 10% warning popped up. I connected the charger, and sure enough, it was able to scan networks. Then when i tried to join a network, it stopped working again, and since then i've been unable to scan wifi. Now 3 resets, and a lot of fiddling later, i'm no further than i was before.
The fact that it was able to scan momentarily points me in the direction of the software, but i'm not so sure anymore.
Hope someone can shed some light on this.

IPhone can't find any wifi networks

I have an original iPhone. It originally ran on wifi networks and Edge, but for a while it has only worked on Edge. When I look under settings - Wi-Fi it says "Not Connected" and lists no networks. My MacBook is connected wirelessly via an AirPort and the wireless info on it lists at least 5 active networks in the area. I have tried toggling between Airplane Mode and not, turning off everything (including cable modem and AirPort) and then resetting network settings, resetting all settings, and erasing all content and settings. I have also tried "Other" under Wi-Fi Networks, but it can't find my home network.
Is there just something wrong with the device?

I have the same problem you did. Was your phone still under warranty or covered under Apple Care? My phone isn't under warranty anymore, so I'm just hoping that I'm not out of luck.

Macbook PRO can't find ANY Wifi network - only at home

Hi, i have a very strange problem with my *Macbook Pro*. I have 3 apple computers at home and one pc. On all machines Wifi works fine, except my new alu Macbook Pro. Important note is, when im with my macbook on other place, office, caffe, *Wifi works fine. But when im at home, this macbook simply can't find ANY network, it's blind.* Interesting thing is, all other computers are several years old and WiFi works fine on them. My friend also bought a brand new macbook pro, and this machine also couldn't fine any network at my home, or in other case when it found networks, it couldn't connect and recieve error message "Connection timed out". I noticed there is new Wifi network in our range, is it possible that this network can cause "blindness" on new macbooks?

*I have to say, I'm really glad you are trying to help guys.*
Well, router is almost on default settings, SSID is brodcasted and i'm not filtering MAC adresses. I tried changed channels, diffrent types of security or no security, no luck.
Guys, maybe i wrote it wrong, but this MacBook can't see ANY network. Around me there are 4-6 other networks which I'm able to see from other machines. So *problem is, this Macbook can't seen ANY network - not just mine.* BUT when i'm with this Macbook in office for example, or any other location, Wifi works....
And one more important thing, this happened suddenly. I was able few months ago to find any WiFi around me with this Macbook. No changes to router, no changes to mac. Problem is somwhere in the middle...try to focus on this: why i'm not able to see any of those cca 6 networks around me. I really think it has to do something with distorted signal and Wifi card used in new macbooks. It's really sick, because all other machines works perfectly (MB 07, MBP 06, PC, iPhone 3g)
I found a log on the router, and it's happening all the time:

IPad can't find ANY wifi networks or personal hotspot each time I return to my home network

I have an iPad 2 as well as iPad 4, iPhone 4 and Macbook Pro. Each of these connect fine to my home network, however my iPad 2 suddenly couldn't find any networks or my iPhone 4 personal hotspot, bluetooth or wifi.
I went to Singapore and hey presto, it could find and connect to wifi networks with ease.
Then I came home to Australia, couldn't find any networks or personal hotspots again. Went to work, same issue, couldn't find the network at work. So took it to the Apple Genius Bar and it worked automatically again without changing any settings. Reset to factory settings just incase this somehow helped getting it home.
Took it home, worked fine. Recovered from a previous backup and still worked fine.
Brought my ipad into work yesterday, couldn't find my personal hotspot or wifi networks. Took it home, can't find any networks. Reset my modem and it still can't find any networks (or my personal hotspot) even though all other devices automatically connect.
Any suggestions? I suspect when I take it to Japan next week it will probably work fine, then I'll come home and it probably won't. Is it some sort of software issue? Why would it stop working every time I take it out of my home network and bring it back?
I have all the latest updates.
Thanks in advance and reading through!

Does the ipad have any management software put on by your workplace ? If so this my be somehow disabling your wifi. The other thing it may be is the wifi channel your wifi is broadcast on but as it happening to you with a lot of access points it prob isn't this it may be a hardware issue, you could take it To an apple store and if it works there try connecting it to your phone. You could also try this, go to general > one of the last options (between VPN and reset) is profiles (This only shows up if u have profiles installed) if you have profiles go into it and delete the profiles then restart. this may help. Good luck

I have just unpacked My new IPhone after setting language The Phone can not find My wifi Network. My orter devices has no problem so there is no problem with My wifi net

My 13 inch Macbook Can Not find ANY wifi networks! Help!

I turned on my Macbook today only to find that no wifi networks are showing up, not even the neighbors! Im connected to the eather right now. My roommates laptop PC can connect fine. I need some help fixing it. Why is it not finding ANY networks at all?

Open System Profiler and check if the compter can still recognize your wireless device. Try resetting the SMC as well and see if this helps.

MacBook pro can't find any wifi networks. HELP PLEASE

Ok so my late 2011 MacBook pro15" starTed dropping out of my network every now and then. Rebooting it got it hooked back up again. Now just a few weeks ago its not picking up any real wifi networks (according to my phone and what my computer showed me before there's a bunch in range). It shows this network called setup as the only wifi network in range and when I click on it, there is this little grey picture of a computer where the wifi bars should be.
Xbox, phone and all of the roommates devices are hooked up just fine.
I've taken it out to a couple of coffee shops and its the same thing. Either seeing no networks or that setup thing.
I've tried restarting, verify and repair disk, deleting all of my preferred networks. I don't know what else to do.

Also I've tried to use one of those usb WiFi adapters that essentially bypasses the computers airport card. That shows all the networks in range but will fail to connect to any of them.

IMAC can not see any wifi networks at all?

IMAC can not find any wifi network at all. A few days ago the Imac suddenly had no wifi and on turning the WIFI on and off it became apparent that when it scans for wifi it can see no wifi networks at all. I have several other computers and they all see the wifi networks fine. I assume it is a hardware issue but the hardware test I preformed comes up with no errors. Anyone got any ideas?

My iphone can't see any wifi networks

my iphone can't see any wifi networks ... i tried to reset network setting and reset all setting and update the ios system but no way

I, too, fear it might be a hardware problem . I removed all security from my router but still no networks appear in the list nor can I connect directly by typing in the SSID. Tried two routers: Apple Airport Extreme and a Linksys something-er-other provided by Bell.
I will give HP a call tomorrow and see if they can sort this out.
Thank you for your help/advice!
Edit: almost certain it's a hardware problem: I clicked on the Help button while on that "Scanning for networks" dialog during initial setup and as one of the "helpful" suggestions, it said my Mac address was 00:00:00:etc.

TS1398 I can not find my wifi network on my ipad. My iphone conected fine.

I can not find my wifi network on my ipad, My iphone connects fine. I tryed restarting the ipad and router. Please help

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

When you say it "can not scan any wifi network" do you mean it is not detecting Wi-Fi networks?
Is Wi-Fi turned on in Settings > General > Wi-Fi?
Have you tried Settings > General > Reset > Reset Network Settings?
Is it just the home network that the device will not connect to? or any network?

My airport can't find my wifi network.

I have a Gateway 2wire that I came with AT&T Uverse. It has been problematic at times, but now my iMac can't find the wifi network at all. It doesn't make sense to me. Sometimes it works great, sometimes it keep dropping off. Me and my wife both have iPhones, my iPhone found the network no problem, hers could not, so I entered it manually and that worked. Then my iMac was working great on it, then all of a sudden, for no apparent reason, it stopped working and now it can't find the wifi network. I can't even enter it manually. The iPhones see it and work fine, my Wii see's it and works fine. But my new blu-ray can't see it either. So why are some of my devices working fine with it, and others can't even find it. I have worked with AT&T a few time and they keep saying it's not the 2wire. I don't believe them, I have read to many reports of similar problems with the 2wire with AT&T. Is there anything I can do to solve this. I keep thinking I wan't to get an Airport Extreme and connect it to the 2wire, I have read that it is possible and will work, but I wan't to know why this router is visible to some devices and not others. Does anyone understand this.

I'm not sure what you mean. You can't find the express to set it up.. or you can't find the network created by the express?

My iPhone 3G iOS 3.1.3 can't find any wifi network.
