IPhone loses contacts on some wifi networks

My iPhone 4S running the latest iOS 7 update has a strange reaction to my home wifi network... Every time I connect to it my contacts all disappear. No such issues with my iPad or my wife's iPhone. After a few hours off wifi my contacts will reappear.

I suppose the problem is on the network. This always happen to me when connected to low speed Wi-Fi networks. Seems Mail doesn't like slow speed, after a certain timeout looks like it assumes there's no Internet and gives up trying. Maybe if you try a different network, such as sharing 3G from your phone, it would work. If the problem isn't the speed, ask IT personnel for information about Wi-Fi configuration on that network — there might be some kind of restriction. I see this problem on my school's library Wi-Fi.

My iPhone loses contacts after update

My iPhone loses contacts after updates. Also I noticed the My Phone option on main contacts screen is now Gone too.

I was finally able to get into Recovery mode using a different computer with iTunes -- one I had never sync'd with. That was after having logged into iCloud and removed the iPad from 'Find my iPad'. This seems to have enabled me to reset to factory settings. That isn't entirely certain, as I had not attempted to recover using the 'different computer' prior to having removed the device from 'Find My iPad'.
Anyway. I then restored from iCloud, (it does give the choice between restoring from Cloud or iTunes).
If one doesn't have one's Apple ID this will not work. Also, now with iOS 7, you need your Apple ID -- NOT your device passcode -- if you wish to disable 'Find My i[Device]' in Settings. And you need to NOT FORGET your device's passcode. Because I'm hearing that with iOS 7 this will cease to be recoverable/resettable if forgotten.
I actually do have 'Find my i[Device]' enabled, even though I am extremely skeeved by the fact that the iPad spuriously disabled itself while riding around in my bag. I also activated 'ask to join wifi networks', so that if it ever *is* disabled it should remain 'visible' to the net, since its basic background processes appear to still run, even when disabled. Not totally sure about this, but I was able to see the device in 'Find My iPad' while it was disabled.

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.

The only other option I can think of is to try a Reset All Settings reset. You won't lose anything, but your phone's settings will ALL be set back to factory default.
If this doesn't work you could try to do a restore through iTunes and set your phone up as new. If that doesn't work, you may have a hardware problem and will need to take the phone in to an Apple store to have it checked out.

Trying to connect my iphone 4 to my home wifi network! my android phone gives me the option of pushing the arrows button on my router and on my android phone but cannot find the "push the arrows button" option on my iphone 4. is this option available???

No such option on an iPhone. Just go to Settings>wifi, tap the name (SSID) of your your home network from the list, then when prompted, enter the password.

Go to Settings > iTunes and App Stores and set to "use cellular data" to ON. Be aware this will use your mobile data allotment when streaming music.

HT4623 i just updated my ipad to ios 8 but i cant connect to wifi network..its says my password is incorrect although i know my password is correct as successfully updated 2 iphones and connected to same wifi network

i just updated my ipad to ios 8 but i cant connect to wifi network..its says my password is incorrect although i know my password is correct as successfully updated 2 iphones and connected to same wifi network

I had the same problem. I reset my network settings as iOS 8 on my iPad 3 seemed a bit slow. When I tried to reconnect to the wifi the correct password was not accepted immediately.
after retrying several times it did manage to join the network. The only observation I had was that I had a weak signal and an iPhone next to me at the time.
make sure you are close to the wifi signal away from any other wifi devices.

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.

My airport is turned itself off and lose contact with my wifi router, trying to turn it on again will not work, I have to restart my Mac for it to work again, but after 5 minutes, the problem is to go back again.

Outgoing mail isn't sent when connected to some wifi networks

Although my outgoing mail goes out just fine on cellular networks, and on my home wifi, outgoing mail isn't sent when connected to some wifi networks.
I use the apple outgoing mail server.
What is unusual however is that my outgoing mail address is not from a standard domain. I have my own.
Could it involve an spr record?

Do you have a wireless network at home and Is the email account provided by your internet service provider associated with your wireless network?
Most, if not all internet service providers block the use of SMTP servers that are outside of their network or not provided by the ISP being used for your internet connection at the time unless the SMTP server is authenticated. The same applies when connected to the internet via the cellular network. Recieving is not a problem regardless the ISP being used for your internet connection at the time.
If the email account is provided by your ISP, most ISPs do not have an authenticated SMTP sever for the email account they provide.
Both my email accounts have an authenticated SMTP server and I've never had a problem sending with either account regardless the ISP associated with a wi-fi network I'm connected to at the time or when connected to AT&T's cellular network - for 2+ years aporoaching 3 years this July.

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.

Problem viewing streaming video in some wifi networks, but not others

When I am at work (university), I can not view YouTube videos or video streaming from news sites such as cnn mobile on my ipod touch 2g.
<m.cnn.com/videos.jsp?ckey-cnn)06#__1_>
When I called Apple support, they had me reset-restore. I still had the problem. I went to the Apple store Genius bar and the problem no longer existed, the videaos downloaded and played from both sites!
But at my diner and at work, I get the message, "This movie could not be played" in a popup box with an OK button. The same message appears if I use the YouTube application. I click on any video, and the same popup appears. In Cnn the popup is preceded by a shaded capital Q that looks like the blue Quicktime Q; in Youtube the pupup is preceded by a YouTube icon in gray with the "Tube" surrounded by the rounded rectangle, their icoon...
At the Apple store the popup never appeared, and the videos downloaded and played.
I have no trouble playing movies I have downloaded from iTunes.
I did not have this problem when I initially got my iPod Touch, and I think it appeared after one of the last two system upgrades, but I am not sure.
I am curious that it the problem happens at two places, my diner and at work.
The speed of my wireless work network, as judged by the ipod app speed test is 9915 kbps download and 6971 kbps upload, so plenty fast.
The first time I noticed this issue was with the application "At Bat Lite" which also won't play video highlights at work.
I do not have WiFi at home
Any thoughts about what would cause this lack of functionality apparantly only at some networks but not others?
Oh, one more piece of data: at work a Macbook will play YouTube both on ethernet and using wifi...
Thanks for any thoughts or suggestions,
Paul

It seems I have two networks available at work, one is behind our firewall, and I login to it. This is the network that I can't view streaming video. There is also a "Guest" network that I don't need to login to. This one works with the YouTube and the news site videos.
Thus, I conclude there is a setting that WiFi network administrators can invoke that specifically can block streaming video on some protocols (whatever the ipod touch uses) and not others (whatever the Macbook uses). But the same router hardware supplying the Guest network does not block these protocols. Presumably this has to do with security on one side of the firewall(?)
Anyway, apparently outside of the WiFi controls available in the ipod touch settings.
Weird...
