IPhone doesn't pick up wifi automatically

Sometimes it does, sometimes it doesn't. Often my iPhone doesn't pick up wifi when I come into a wi-fi zone and stays on GPRS until I go into setting, wifi and then it picks up the network. Sometimes it does it automatically but it's annoying when it doesn't. It sometimes does the same with network signal if you go into a 'No Service' area and then come out of it it often takes a long time to pick up the network signal again. What could be wrong?

These are wi-fi networks your iPhone has connected with previously?
If not, your iPhone won't automatically connect to an available wi-fi network unless your iPhone has successfully connected to the network previously.
You can try resetting network settings at Settings > General > Reset.
This will erase all saved wi-fi networks and settings your iPhone has connected with previously and require manually re-joining every wi-fi network your iPhone has access to when returning within range of such a wi-fi network. This will also reset your cellular network connection.

Just bought a macbook pro 2008, will not pick up wifi connection that my old lap top has very quickly. whats wrong?

I just bought a used macbook pro, turned it on and it will not pick up wifi connection n my house that my old lap top has done very fast and easy wifi connection. What do i have to do to log on to internet with wifi with my macbook pro?

That could be the reason they were selling the old macBook Pro. Does the network utility even see any WIFI networks? If it doesn't, and you know they exist, something with the WIFI might have failed. Can you connect using the wired ethernet port?
You might have to take it to an Apple store or an AASP for a checkup.

Additional things to try.
Try this first. 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.
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 or Channel 6 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.

Note - When troubleshooting wifi connection problems, don't hold your iPad by hand. There have been a few reports that holding the iPad by hand, seems to attenuate the wifi signal.

IMac connects via ethernet fine but iBook doesn't get the wifi connection

I'm not computer literate. I'm told this has to do with the airport sharing but it looks to me like the airport sharing has to do with reading OTHER wifi connections on my iMac. I don't need that. The iMac is connected to the internet just fine. My iBook and my iPhone don't get the wifi connection that it used to get and I can't figure out why not. Thanks in advance for any and all help.

Welcome to the Apple Discussions!
More information would be helpful. Your iMac is connected to your ISP's service with Ethernet? And you are sharing that internet connection for the iMac with other Apple devices from the iMac's AirPort card? Do I have that correct?
If so have you shared that internet connection according to Apple's protocol for doing so?
My Mac mini is connected to the internet by Ethernet cable to my ISP's gateway. I am sharing the Ethernet connection to two iPod Touches via AirPort from my Mac mini. This is how Apple says to configure a Mac to share the connection;
1. In Sys Prefs/Sharing highlight Internet Sharing (do not check the box)
2. Share the connection from: Ethernet (from the dropdown menu)
3. To computers using: AirPort (check the little box)
4. Press the button AirPort Options...
5. Name the Network
6. Use Automatic for the channel or assign a specific channel
7. Encrypt the network with one of the choices
8. For sharing with a non-Apple device; PC laptop, MP3 player, etc, you must use only a 5 alphanumeric character, 40-bit WEP password or only a 13 alphanumeric character 128-bit WEP password. That does not apply if you are setting up sharing for Apple devices only.
9. Press OK
10. Check the box for Internet Sharing
11. Answer any dialog boxes that pop up
Any other forms of configuring sharing the ethernet over AirPort ususally results in various issues.

HT3986 My Windows 7 doesn't detect my wifi connection, how do I fix this?

I just recently installed Windows 7 Home Premium into my Macbook white late 2009 edition and my wifi connection cannot be detected by windows but when I plug in the ethernet cable from our broadband router, the internet works. What do I do? Please help me.

Did you see a thread pretty much same duplicate as your question? also using Airport.
https://discussions.apple.com/thread/3808608?tstart=0
I don't have wireless but in Vista there was a wireless configuration wizard.
And yes set up wired first. Install Apple driver, and based on dozens of identical threads, probably update the driver - via Device Manager, find what device and manually install what you need.

Mac mini constanty drops off wifi connection and then reconnects

New MacMini constantly loses wifi connection. IPad a few deetaway has excellent connection.

This issue cropped up for me when I upgraded to Leopard, and you will find similair threads in the MacBook discussions. It appear to be a timing issue as the network stack wakes up from sleep. The 2 simples solutions are to either turn on SSID broadcast (this worked for me) at the router or to turn Airport Off and On when the mini wakes up. Several folks in the developer area have submitted bug reports, I expect this will be addressed in short order.

Problem with wifi connection since installing Lion OS X

Has anyone had problems since installing Lion OS X with there wifi connection? I keep getting bumped off my connection in multiple different locations ....that i never had a problem before. I installed Lion on my laptop and my Mac and I am having the same problem with both. Is there something i need to change on my settings?

One way to look at this problem is to install a Stumbler program and look at what channels are being used in your immediate area. You may find the channel you are using is very busy, and switching your Router to a channel with less competition, or setting your Router to automatic channel selection, improves the situation.
Another way to address this problem, especially since it seems to correlate with software Upgrade, is to set it up from scratch again:
System Preferences > Network > WiFI/Airport > ( Assist me ) > ( Set Up ) ...
... and re-specify from scratch, especially using a New Location.

I let my Macbook die and now it doesn't recognize old wifi connections and doesn't trust internet.

Hi-
I have often let my Mac die, while going to sleep etc, this is the second time that when I charge it back up and turn it on it doesn't work the same. It doesn't remember the passwords of old wifi networks that I have told to "remember this network." Then when I do retype the password and connect there's a screen on the internet that says it cannot trust site like Facebook or Google and sometimes there's "add exception" sometimes there's not. This is on Mozilla Firefox also.
Last time this happened I can't remember what I did but it eventually started going back to normal....But now, I don't know, any suggestions??

How much free space on the HD? You should have 30 GB free for the system to do "temporary work", such as saving preferences and internet settings in browswers.

HT4199 Mac Cinema display interfering with WiFi connection

Year-old MacBook Pro works fine with WiFi UNTIL I plug into my older Mac 21" Cinema display - which I need to do via Rocketfish adaptor, and a female firewire adaptor. Plug in - offline. Unplug - back online.
I have messed with network settings repeatedly, and got things running for a small pocket of time. Restart the day after, back offline.
Note that my older MacBook Pro running Snow Leopard doesn't have this issue - only the new computer, which requires the adaptors to do so.
Any help is greatly appreciated - this is killing productivity!!!

Actually, Niel is half-right. After searching for over a month, and researching all sorts of options that "might" work, I went with the Atlona Dual-DVI to Mini DisplayPort (see link above - discontinued so you'll have to look on Amazon or eBay) and the Apple Nvidia 6800 GT DDL video card (look on eBay for approx. $70-$100).
To achieve full native resolution on the Apple 27" Cinema LED, (2560x1440), you'll have to have both a Dual-DVI to Mini DisplayPort converter/adapter (like the Atlona), IN ADDITION to one of the higher-end "build to order" video cards like the Nvidia 6800 GT DDL or Ultra DDL which can support resolutions greater than the stock 1900x1200 on a single DVI-equipped stock card that came with most PowerMac G5's.
Hope this helps clarify a little for those looking to stretch the lifespan of those bastardized G5's. ;)

Equium A210 doesn't pick up WLAN connection

Hi
Why doesn't my Equium A210 - 1c4, model PSAFJE pick up any wireless connections?

Hi!
You can only connect to WLANs where you know the password.
If you see a WLAN, try to connect, enter your password and thats all.
On some WLAN you must know the SSID because its not visible.
But maybe you can explain your problem more exact.
Bye

My mac doesn't pick up the signal strong and everybod elses PC does

I go to a school that has a wireless network on campus. My airport connection works fine when I am in a room with a signal router, but when I go to a room without a direct router my mac only pics up one bar! The frustrating thing is that all the PC laptops get the signal just fine.
What's going on? what should I do....

Check the photos in KB 108039, Properly attaching the antenna on an AirPort Extreme Card to ensure that the antenna wire is properly connected to the AirPort Extreme card in your iBook G4.

Can a mac and windows share a wifi connection?

Say "Thanks" by clicking the Kudos Star in the post that helped you.
Although I work for HP my posts and replies are my own
Please mark the post that solves your problem as "Accepted Solution"

Yes, Windows and Mac computers can share the same Wi-Fi network.
Are you setting up a new network or are you adding devices to an existing network?

IPhone 4S continuously drops and picks up wifi connection

I have an iPhone 4S, OS 6.01. At home, it connects and disconnects from my WiFi router continuously, as in the wifi icon and the 4G icon keep alternating every second (literally).
While this is happening, my iPad 2 is sitting a foot away streaming video fromt eh same network without issue, and I am writing this on my MBP over the same network.
I have tried rebooting the phone and resetting the network settings.
Any help appreciated, this is driving me crazy.

I did restore from a backup, would restoring as new help? also what about all my pics and stuff on my phone? I wouldnt get them back on the phone if i restored as new, right?
