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.

HT5569 cannot scan for wireless networks

I cannot connect to any wi-fi network. My wif- is working at home, I am connected right now to the wi-fi with my computer, but this phone wont connect to any network at all. I have read the recommended steps posted on this website. I have tried rebooting, resetting the network connections, etc. I tried manually entering the name of the network and the screen says "cannot scan for wireless networks". I have had this problem since upgrading the operating system a few days ago. Nothing is working and this is very frustrating.

After being to the apple store twice, trying various restore attempts and a host of other things. I have found out the phone is screwed because of the apple update. I ended up losing content, losing the ability to connect to wifi, so lost the ability to get my cloud backups, lost my ability to get my work email as well and that is that. I have spent hours dealing with this now. Apple store told me I should just upgrade my phone to a 5 when my contract is up cause there is nothing they can do. If I had known all of this would have happened I would never have updated. The guy at the apple store told me he didnt do the update on his phone because of all the issues with it. Thanks Apple. Thanks for sending out a system upgrade that really downgrades our phones and ****** us off. My time is valuable as is all the data that is lost. I am royally ****** off. You have lost my loyalty. I might just upgrade to some other type of phone instead of an iphone.

TS1398 cannot scan for wireless networks

My phone will not connect to home wi-fi. My DH's iphone is connecting fine, but mine won't and it doesn't list any options for network connections. wi-fi is ON. Ask to join networks is ON. Error msg "cannot scan for wireless networks". I turned the phone off and also reset network.No changes....Thanks in advance for your help

I have had this issue of not scanning for WiFi networks as well. I just tried the following, and it has worked for me, at least for the last 12 hours or so:
1. Turn ON Airplane Mode
2. Power off the phone normally: Hold power and home keys for 6 sec, then swipe the "power off" slider.
3. Waited 1 minute
4. Turn on phone, wait for it to reboot itself
5. Turn OFF airplane mode,
Immediately, all WiFi networks popped up, and I could select my home network with the same saved password etc.
Of course, this might not work for every case, but it's easier than a phone restore and worth a try.

Ipad 2 Cannot scan for wireless networks

Why can't my ipad 2 scan for wireless networks? Was on airport mode but turned airport mode off. Turned on wi-fi. Reset network settings. Tried turning ipad off and turning it back on. Keep getting same message. Could not scan for wireless networks. Any ideas?

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.

Cannot scan for wireless networks

Since last night has been connecting to 3G and wi-fi on and off, and now won't find the wi-fi at all, circle keeps going around. try to enter it manually but it says it could not scan for wireless networks. have tried resetting network settings, turning the phone on and off but nothing works.
Did drop the phone yesterday but am hoping i havent broken some internal part and that someone can point me in the right direction!!

It sounds like you DID break something, or at least loosen a connection when you dropped it.

Ipad2 "cannot scan for wireless networks"

My iPad2 is about a year old and was able to scan and connect to networks just fine up until a week a go when it stopped scanning for networks. I am usually able to connect to the wireless network at my school and home [along with other various hotspots like Starbucks] just fine but within the last week have been experiencing no luck in connecting to any of my potential wireless networks. I have tried resetting the network settings, rebooting the ipad, my airplane mode is truned off and my routers have been reset and set back to original settings, in a nutshell I have pretty much tried everything the "Apple Support Community" has told me to do and still have no luck. Please help.

Is Wi-Fi grayed out on your iPad? Does it see any the Wi-Fi networks?
If it isn't grayed out, this Apple doc is a good place to start -> iOS: Troubleshooting Wi-Fi networks and connections

STILL cannot scan for wireless networks

I'm having the same problem that everybody else who posted with this thread has. I've tried everything I can think of, but the most popular response to these threads seems to be return it under warranty. I'm out of warranty and cannot afford a new phone, anymore than I can afford the data overages that result from not having wifi. My last iPhone did exactly the same thing, except, back then, I could afford to buy a new one; now, after reading so many posts, I'm coming to the conclusion that apple hasn't figured out how to make a durable antenna yet. This seems to be a common problem with iPhones, which totally defeats the whole purpose of my buying one in the first place...reliability. This is my last attempt before I swear off this company as unreliable (the kiss of death for me) and see what the dark side has to offer (I dare not speak their name on an apple forum, but you all know who I'm talking about:). So PLEASE, somebody help. I really have loved my phone, but I have to be realistic about where I drop another $300+.
PS: I've upgraded iOS's twice, and this all started before the update, so I really don't think it's what some other people think is an iOS issue.

Dude, I am SO sorry. I neglected to take into account that some people are emotionally attached to their inanimate objects and lose the ability to think rationally, as if someone had insulted their child. While I love what my phone can do for me, it never occurred to me to love the phone itself, given that it's an object, incapable of reciprocating that love. Also, since I don't own apple stock (or even know if it's publicly traded) I have no vested interest in their future. They are a cash cow though, I ought to diversify my portfolio...my bad:/
Apologies out of the way, I have answers to your comments, and a solution to my query, that having spent so much time researching, I know can be hard to find. I'll address your comments in the order they were received; I'm assuming you'd want to know, cuz really, what kind of a loser would waste their time with those kinds of comments if they weren't sincere, and how sad would someone have to be to say such things in response to someone's plea for help? Surely, not you :)
-It has everything to do with the "antenna". In quotes, b/c 4th gen technically doesn't have a traditional antenna (I know how important technical issues are to you now).
-Antenna issues on the 4th gen have a very well documented history of failing. You may recall that the original would lose wifi if you touched the borders. Apple confirmed this problem, advised people to use a case, and set to rectify it with the release if the 4s. Common, in this context, refers to every single iPhone 4 sent out on release date... So if they sold >100million, then that's how many times it happened.
-While I still prefer the iOS to android, I'm a free thinking individual, not slave to any phone manufacturer, and I have a life I'm already ignoring way too much doing this, to waste my time documenting research; especially since I never said it wasn't a problem elsewhere, just that it clearly is a problem here.
-Yes I tried everything. Being of at least average intelligence, I found your advice on my very first google search. So I appreciate the advice, but I only came on here as a last ditch effort (as originally stated) after having exhausted other avenues. I'm unsure as to why you doubt whether someone would try the troubleshooting steps, given that they're the only ones apple offers, but I'm guessing it has to do with your sunny disposition, so I won't ask.
-I don't know what you mean by "flame", but given the context, I see you've mistaken me for someone that cares to "bash" a piece of equipment that is, by any standard, a miracle of modern innovation. Of course this is true of all smartphones, but it seems you only have eyes for one company so I'll stick to that.
...again, I apologize for not being more conscious of your sensitivity.

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.

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 - 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!

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:

If the first set of steps don't help, try the "Unable to locate..." steps, which involve resetting network settings.
Thanks for reaching out to Apple Support Communities.

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.

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
