TS4036 I have an Iphone 4S. I used to backup automatically to the cloud. Since I did the software update I not longer can connect to any WIFI network! I getthe message that it could not scan for wireless networks

since I updated my software to the IOS 7.0.4
I am unable to use any WIFI network
i cannot connect to my home wifi network I am unable to do any backups. I have backed up my phone onto my Itunes account on my computer and I reset my phone...this did nothing but lose some of my pictures.. PLEASE HELP!

I read the article thanks. I tried the settings-general-reset-reset network settings-reboot system-go to wifi settings-select wireless connection-select the ">"-symbol-select auto for http proxy. I was optimistic about that because I thought I changed some setting somehow to cause this problem, but it didn't work. More specifically, I did connect successfully and browsed the Internet for a good while, but then I put down the phone for a minute, the phone went into sleep/power save mode, and when I picked it back up a moment later it was no longer connected. Dang. Had to select the connection and use my password yet again.
Another valuable bit of info for you. The only network with which I have this problem is my home. I use all kinds of devices at home and no other devices have this problem. Also, I use this iPhone all over with various wifi networks at hotels and starbucks and family's homes with no issues whatsoever. It remembers and automatically reconnects with every wireless network except the one in my own house.

TS1398 cannot scan for wireless networks on my iphone 4s

good morning. my iphone 4s is not "seeing" any wireless networks. the message I got is cannot scan for wireless networks
I have tried most all setting without success. could ther be a hardware problem?

Settings > General > Reset > Reset Network Settings.
Basic troubleshooting from the User's Guide is reset, restart, restore (first from backup then as new).
If none of this resolves the issue, then a hardware issue exists. The device is still under warranty... take it to Apple for replacement if it gets this far.

IPhone 4S - Could not scan for wireless networks - help needed please

Hi
Can anyone offer any advice please.
My 4s has developed an wifi issue. It cant scan for wireless networks My bluetooth is intermittent also.
I have turned it on/off, rebooted, reset all networks, reset to factory settings, set to airplane mode, set to do not disturb - everything and all to no avail.
I am under a two year contract with Vodafone and went into their branch at Merry Hill, Dudley today and they failed to help me saying it was nothing to do with them.
I am at a loss as to what to do. I have not had any accident with my phone and it is still in mint condition.
Can anyone please offer any suggestions on what to do.
Many thanks.

Apple's out-of-warranty policy is a feeble attempt at covering up it's issues and is a clear cut demonstration for their lack of respect for its user base. Their WIFI/Bluetooth dropping issues have been around for several years now and it started within the last 3 IOS updates. Apple engineers acknowledge this problem and don't have a solution yet... this was confirmed at the Genius Bar at their Nashua, NH outlet. My phone is 6 months passed warranty and my Verizon contract isn't up for renewal for another 6 months.
There are a lot of complaints about this (a LOT), yet Apple continues to stick its head in the sand instead of owning up to providing shoddy hardware and/or glitches software. They certainly don't want to be in the business of replacing phones, so they put the onus on us by charging $200 for a replacement... such a deal for Apple!
Apple's support communities are basically useless on this subject with a lot of screwy so-called solutions to work around their flaws. I've seen one fix where you heat up the phone with a hairdryer until the temp warning appears and then refrigerate it for 10 minutes... then BINGO, it's all fixed! Ya right!!!
Resetting network settings, or all settings (including a complete reset) is ineffective and appears to do nothing more than to further upset Apple users once they realize that they have wasted their time following Apple's so-called fix.
I just wonder if or when Apple pulls it's collective head out of the sand will they be able to see that their competition has surpassed them by leaps and bounds. There really isn't any good reason to stick with Apple now-a-days since their conscience passed away. Their competition offers superior technology while Apple continues to impress up with new connector technology and placement of their sockets.
I am finished with Apple and am incredibly sick of their spoon feeding what they want rather than what we want.
The best way to make Apple improve is to provide them with a taste of their own WIFI/Bluetooth offerings by DROPPING THEM!
They have abandoned us and have no problem trying to charge us to replace their flawed technology instead of doing the right thing!

IPad could not scan for wireless networks

My iPad 2 was bought in April 2011. And just a few hours ago it suddenly disconnected from my home WIFI.
I tried to reconnect it, but it either kept scanning the network or kept prompting the warning message "iPad could not scan for wireless networks".
My Macbook Pro, iPhone and another iPad 3 were all working fine with my two different WIFI points at home yet only my iPad 2 couldn't scan both WIFI at all.
I have tried to:
1. Reboot IOS (turn it off and on)
2. Take out sim card
3. Reset Network Settings
4 Reset All Settings
5. Restore iPad from iTune
I've called Apple, obviously they had no clues about this problem and they just adviced me to send in my iPad 2 for 1-to-1 change.
This seems to be a common unsolved issue for apple users. Has anyone solved this before?
Now I'm worrying will my iPad 3 get the same issue in future. it makes me quite frustrated

Look at iOS Troubleshooting Wi-Fi networks and connections http://support.apple.com/kb/TS1398
iPad: Issues connecting to Wi-Fi networks http://support.apple.com/kb/ts3304
iOS: Recommended settings for Wi-Fi routers and access points http://support.apple.com/kb/HT4199
Additional things to try.
Try this first. Turn Off your iPad. Then turn Off (disconnect power cord) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
Change the channel on your wireless router (Auto is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
Another thing to try - Go into your router security settings and change from WEP to WPA with AES.

TS1559 could not scan for wireless networks.

Wifi not working on my Iphone. All I get is "Could not scan for wireless networks." Does anyone have a solution to this problem?

If no change after powering the iPhone off and on and/or after a reset which is similar to a computer restart, try resetting network settings on the iPhone at Settings > General > Reset.
If no change after that, try restoring the iPhone with iTunes as a new iPhone or not from the backup but update the iPhone's backup immediately before doing so for later use.
If no change after restoring the iPhone with iTunes as a new iPhone or not from the iPhone's backup, the iPhone has a hardware problem.

"could not scan for wireless networks" iphone6 or iOS 8?

new iPhone 6 with iOS 8. Wifi works fine for a few hours and then drops. The wifi connect screen sits there spinning and if I attempt a manual connecation I get the message:
"could not scan for wireless networks"
Only solution so far has been rebooting.
No issues with older devices and iOS 8. Just the iPhone 6.
As this issue seems to come out every time Apple release new hardware I am hoping it's just a bug that will be squashed and as such wanted to bring it up on the forums. Will also report to support.

Hi Uncle Ook,
From what I've read, other iPhone 6 users have experience this issue too. I've read that by doing these steps it may help resolve your issue:
Open Settings
General
Reset
Reset Network Settings
Enter your Passcode if prompted
Tap Reset Network Settings
What this will do is reset your network settings. By doing this we'll reset any issues to default settings that'll help fix your issue by setting the network settings to default settings.
You'll see a series of different screens. This is normal. Just wait until it's completely done. You'll know when it's done when it takes you to the lock screen. You'll need to unlock your iPhone after that and try reconnecting to your wireless network that you were attempting to join. I'm not sure however that these steps will help permanently or temporarily, but I'm sure Apple will fix this issue within the next update that comes out. I hope this helps, and if you have any other questions please don't hesitate to ask.

Iphone 4s "Could not scan for wireless networks"

I haven't had any issues with wifi except for today, when I noticed that my phone would not recognize my home wifi. I checked, and the wifi here is working fine. My roommate's iphone is connecting fine. My laptop is connecting fine. When I try to connect manually to my network, I get the message "could not scan for wireless networks". I have tried restarting my phone. I've tried just turning wifi/airplane mode on and off and there is no improvement. I've also reset network settings and still nothing.
Forgive my ignorance, but I am not a tech person so if anyone can help you kind of need to phrase things like you're talking to a small child. Please though, if anyone has any suggestions I would SO appreciate it!

Could this be the problem?
iPhone 4 Modem Firmware : 3.0.04
iPhone 4S Modem Firmware : 2.0.10
Wifi is working on my iPhone 4, NOT on 4S -
Why is my new 4S I got yesterday using a 2.0.10 firmware, isn't that old?! Isn't the newest 4.0+?
I am so tired of trying to figure this out.
The Wi-Fi addresses in the About settings are different on both phones too.

Iphone 4S Message - "Could not scan for Wireless Networks"

For the last couple of days I have been getting a message, "Could not scan for wireless networks" when I try to connect to WiFi. WiFi connection is sporadic and intermitent at best when I do mange to connect. My phone is set to automatically recognize and connect to familiar networks. All other devices in the area currently have no issue recognizing and connecting to my home WiFi network. I have reset, turned on and off phone. Thanks for anyones suggestions. I have a feeling a trip dowtown to visit Apple is in the cards?

Hello there, MattBrear.
The following Knowledge Base article provides some in-depth steps to try in resolving your wi-fi connectivity issues:

Error: "can not scan for wireless networks" 1st gen iphone running 3.1.2

My iphone will no longer scan for wireless networks. I am running an airport network via my imac and the rest of the computers, as well as two iphone 3GS phones can see it, but my 1st Gen iphone now gives me the error "can not scan for wireless networks". I have done the Home + Power button thing, reset the network settings and no help yet.
Any suggestions?

OK. There are reports of bad wifi chips, but lets try some more things first.
I assume your router is set to b/g compatible & not "n" only, correct? The iphone only works on g. Next, try this: Shut down the WiFi, and turn off "Ask to Join Networks". Then turn the iPhone completely off, by holding the top button down until the red slider came up, slid it off, and wait a few moments.
Turn the phone back on, then turn on the WiFi, and then "Ask to Join Networks".
See if that helps.

My iPad will not scan for wireless networks.

I've tried all the obvious, on-off and then on again. I know there's a network here, but my screen just sends this message when I try to connect:
"Could not scan for wireless networks". What do I do?

it happends to me sometimes. put the plain mode for a few seconds. you can after go to normal function. normally my iphone start searching for the wifi just after that !

HT201210 I tried to restore my iPhone 4s through iTunes and received error message that Restore could not be completed due to error 2003. Phone now not recognized in iTunes, with prompt to restore, phone w/screen with iTunes symbol and can't use.

I tried to restore my iPhone 4s through iTunes and received error message that Restore could not be completed due to error 2003. Phone now not recognized in iTunes, with repeated prompts to restore phone. Now phone w/screen with iTunes symbol and USB cord can't use. It appears the phone has been restored, but I cannot activate it.
I disabled my anti-software, iTunes and computer software (microsoft vista) are both up to date, I restarted the computer several times. My usb ports are working properly. I followed the troubleshooting suggestions from apple.

yes did you buy it of somebody or a well known company such as apple or carphone warehouse?
and i mean the phone would have been activated in the first place with the sim card you get given when you first get the phone.
trying to activate the phone with another sim card that you did not get when you brought the phone may result in you not being able to activate it
no worries

HT1766 I backed up to my PC and attempted restore but I keep getting an error message that "iTunes could not restore the iPhone because not enough free space is available." I have a 32GB iPhone; only 13GB used!!! HELP! iCloud backup/restore did not work

I backed up to my PC and attempted restore but I keep getting an error message that "iTunes could not restore the iPhone because not enough free space is available." I have a 32GB iPhone; only 13GB used!!! HELP! iCloud backup/restore did not work either! How can I resolve this problem to restore from back up.

If you're not a developer then you really should not have upgraded.
I'm unsure how you can fix this as you have already done a back-up on iOS 7 and apple don't support firmware downgrades.

Bummer..my phone quit scanning for wireless networks

in Baja on vacation and my phone suddenly stopped scanning for wireless networks. Got any ideas? My partners iphone works fine. I reset my wireless networks in the settings window. I tried manually entering the network name and pass code. I removed and replaced my sim card. I'm hesitant to synch, backup and reset my phones settings since I definitely don't want to compromise it further. Been there done that.

Here is a solution that might help. I too had the unhappy message of " could not scan for wireless networks". Thinking it was a wifi hardware problem or software problem made me give up until an idea hit me. Maybe it was an app. that was giving me problems. So I deleted an app. I had , which was Devicescape Easy Wifi, and did a reset network setting. This solved my problem. So look at your app. list and delete any wifi app. and see if that works.

Stuck interrupt when scanning for wireless networks (Athero chipset)

I'm working on getting wireless running on my Thinkpad T40 with an Atheros AR5211 a/b adapter. The ath5k module loads automatically, and the dmesg output seems to indicate that it is properly detecting the card:
% dmesg|grep ath
[ 4.767272] ath5k 0000:02:02.0: registered as 'phy0'
[ 5.042780] ath: EEPROM regdomain: 0x61
[ 5.042787] ath: EEPROM indicates we should expect a direct regpair map
[ 5.042793] ath: Country alpha2 being used: 00
[ 5.042796] ath: Regpair used: 0x61
[ 5.478542] ath5k: phy0: Atheros AR5211 chip found (MAC: 0x42, PHY: 0x30)

[ 5.478553] ath5k: phy0: RF2111 2GHz radio found (0x23)
I brought the interface up using ip:
% ip link show wlan0
4: wlan0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN mode DEFAULT group default qlen 1000
link/ether [redacted] brd ff:ff:ff:ff:ff:ff
The trouble comes when I try to scan for wireless networks. I run "sudo iw dev wlan0 scan". At this point, the system becomes very sluggish, and the load average began to monotonically increase. The scan never completes; I left it for 15-20 minutes and cut it off when the load passed 3.5. The load average did not go down after iw was killed. Checking in top, the CPU was pretty evenly split between a kworker process and ksoftirqd, even with the scan terminated.
I've searched around, and while there are all manner of problems reported with getting various wireless configurations to work, no one seems to get tripped up at the scanning phase like this. Does anyone know of diagnostics I could try (or perhaps other scan tools?) to narrow down what is actually causing the CPU to get hammered?

I got a chance to play around with this a bit more, trying wireless_tools this time:
% sudo iwlist wlan0 scan
wlan0 Failed to read scan data : Resource temporarily unavailable
As before, the load average then continues to increase until the system becomes unusable. This would lead me to believe that I have a driver or kernel issue, since that would be the commonality between the two tools.
The other interesting output is this:
% dmesg|tail
[ 280.973316] ath5k: phy0: too many interrupts, giving up for now
[ 280.989985] ath5k: phy0: too many interrupts, giving up for now

[ 281.034543] ath5k: phy0: too many interrupts, giving up for now
[ 281.049984] ath5k: phy0: too many interrupts, giving up for now
[ 281.064543] ath5k: phy0: too many interrupts, giving up for now
[ 281.079983] ath5k: phy0: too many interrupts, giving up for now
[ 281.094544] ath5k: phy0: too many interrupts, giving up for now
[ 281.109122] ath5k: phy0: too many interrupts, giving up for now
Looking at longer tails, this message repeats many many times, interspersed with:
net_ratelimit: 321 callbacks suppressed
With various values for 321. Some interrupt getting stuck would make sense for why the load average blows up, but I really don't know how to fix that ...
I verified on the ath5k site (http://wireless.kernel.org/en/users/Dri … rted_Chips) that my chip is supported:
% lspci
02:02.0 Ethernet controller: Qualcomm Atheros AR5211 Wireless Network Adapter [AR5001X 802.11ab] (rev 01)
Any tips for what might cause a stuck interrupt like that?
