My iMac won't connect to Youtube via wifi. Ethernet is ok.

For reasons I cannot discover, I cannot open Youtube.com via wifi on my iMac. It will open when ethernet is connected. This is the only site that seems to be affected. It stalls for a second or two, then I get a blank screen and the URL changes to www.youtube.com/?tab=w1. I read through every forum I can find, tinkered with the network settings, deleted cache files for the browsers, etc. Firefox, Safari and Chrome all do the same thing. It was working fine for awhile and I don't believe that we changed anything that caused this, so I am at a loss. Has anyone else had this issue and know how to solve it?

Palm TX won't connect to computer via WiFi for Hotsync

I've tried the network Hotsync on all my computers, XP, Vista 32 and Vista 64 (which started the whole attempt) and the device fails to connect to the computer, even when I put in the IP address.
My wireless network sees the Palm and I am able to access the Internet through it, but it won't connect to my computers. Any suggestions?
Post relates to: Palm TX
This question was solved.
View Solution.

Here's my Wifi Hotsync help file:
Wifi HotSync with a TX
1. On your PC, locate the HotSync Manager (little HotSync icon in the lower right tool tray on a Winbox). Click on it and check off "Network", then click again and select Setup.
2. Pick the Network tab up top in the window that opens, and find your HotSync name in the list. Make sure it's checked.
3. Tap the TCP/IP button, and look at the IP address listed for "Primary PC Address". Write it down.
4. Turn on Wifi on your Palm and connect to your router.
5. On your Palm, select the HotSync program and tap the word "Network" above the HotSync icon in the middle of the screen. Below it, enter the IP address you wrote down in step 3. (Include the periods!).
6. Tap the big HotSync icon above the IP address, and hold on!
7. If you're holding on, and nothing happens try a wired HotSync, then try the Wifi HotSync again. Sometimes, information has to transfer from your PC after you check off the Network option. Also, be sure to watch for any Firewall activity asking you about "HotSync.exe is trying to access your hard drive" etc. You may need to set a rule to allow it.
On your TX, check these settings from the pull-down menu in Hotsync:
Modem Sync: Network
LanSync: :LANSync
Network Setup: (Wifi should be listed as one of the networks)

Imac will not connect to Internet via wifi or Ethernet since upgrade.

since the upgrade to Yosemite I am unable to connect to the Internet via wifi or Ethernet. All my other devices ipad/IPhone 6 work fine so issue is not with ISP.
Any help would be greatly appreciated.

I Have tried starting in safe mode and my internet works fine. But I lose all connectivity after reboot into normal mode.

Airport Express won't connect to internet via WAN ethernet

I have new model Airport Express (AE)
I am attempting to use the AE as a wifi router in my office. I'm sure the office has some sort of secure internet, although when I hardwire my computer to the internet via ethernet my computer connects immediately to internet with no passwords or logins necessary.
I have set up my AE to create a new wireless network. It is ready to go, but it does not recognize that it is connected to internet. Ethernet cord is plugged into WAN input, and other end is plugged into wall for office supplied internet.
AE will not recognize that it is connected to internet.
I assume this is due to something with the office supplied internet being secured or "special." Is there a work around here, or suggested next steps?
Thanks.

If you get all three together, "Ethernet unplugged" would pretty much explain the other two errors. Troubleshoot that first.
Is the same ethernet cable you are using with the AE the same one that worked with your computer? Is it oriented in the same direction (same end to the wall) as when it was used with the computer? Your office might use a non-standard cabling system or be taking some other measures to deter the use of foreign equipment.
Have you asked your office's technical support folks for any special instructions?

How many iMacs can I connect on TC via wifi?

Hey,
For school where I am working we use a time capsule with 12 iMacs. Two of them can't contact the airport of TC. All the others do! I tried to replace the TC a better place: no result!
Thanks a lot,
filip

Can you split the load between 2.4ghz and 5ghz.. do it deliberately.. ie take the TC wireless off auto channel and set it yourself. Give a different name to 5ghz so you set the whole network, wireless channel and band and which computers join to which band. I would also suggest any computer updated rather than clean installed to Mountain Lion could be messed up wireless drivers.. are you using a radius login names?

Mac Book Pro won't connect to internet via either Ethernet or wireless

A month ago my macbook pro suddenly stops working wirelessly with my virgin media router showing it has connected but no internet access. I have a second computer so i hadn't addressed the issue untill now. On a different virgin media router at my university flat I have exactly the same issue. I can connect to the Wi-Fi but it has no internet access and an IP of 169. so it is being rejected somehow. I have tried several things but they haven't worked. I stress that the ethernet doesnt work either which is unusually of most posts on this topic. If anyone could help me that would be much appreicated.

I had the exact same problem, here is what helped me, hopefully it will help you also...
I have been using my airport disk (edge_diskgo external HD) now for about 3 weeks, it has been rock solid... until tonight after the firmware update.
My macs could not locate the airport disk, but my pc's still could.
(Maybe this was how the security problem was solved? You can no longer access the Airport disk from macs? Brilliant!)
It turns out that all I had to do on my both my macs is go to
Airport disk utility (just type that in spotlight) and check
both boxes: Automatically discover Airport Disks
Show Airport disks in menu bar
Then I went to the top right hand side of the menu bar, and clicked on the airport disk utility icon, clicked on my basestation name and entered my basestation password.
I also had following settings in Airport Utility/Disks/File sharing:
File sharing is enabled
secure shared disks (with base station password)
Guest access (not allowed)
Share disks over ethernet wan port (checked)..
Advertise disks globally using bonjour (not checked)
My drives are back up with all of their contents, working now, we will see how they do tomorrow.
Thanks for all the help on this post, special Thanks to trevinwagner, hope this helps someone else.... its very late, Goodnight all

My iMac won't connect to my network

My iMac won't connect to the internet anymore. I can only get internet connection through someone elses network.
It connected okay to my network when I first plugged it in. Everything was coming up roses and such. I'm thinking though it might have something to do with my pc. I gave my mom my pc and cleaned off everything. After re-installing the drivers, programs, and re-installing the wireless info on the pc, my mac won't connect to the network
There is a password for connecting to the network a wep 128. But my mac keeps telling me the password is wrong. And the only way to connect to the interent for me is via the Dlink connection.
We have a Linksys Wireless Router (WRT54G)
My mom has windows XP with wireless capability
My mac has the airport extreme already in the computer
I'm sure the problem is something really simple and minor and that I will kick myself for not figuring it out. :S
But any help would be great
iMac Mac OS X (10.4.8)

The only other connection I get is through a unsecured dlink.
I tried using network assistant to get on the linksys network but when I put in the password for it I keep getting a message that says invalid.

Can't connect to YouTube via iPhone 4

Suddenly, I can't connect to YouTube any longer. My sign in info is gone and I can't sign back in because it won't connect to YouTube to even do that. I de-synced and resynced everything and it didn't help. Everything else on my iPhone 4 is working normally.

Okay, it seems that this has something to do with Google's new privacy policy. Go to google and sign in. Click the drop down list on the upper right hand corner and click account. Then go to security. Now you click on authorization for apps and sites. Now you can generate a 16 digit code and write it down. Name it for your specific item but first delete any entries for previous ones for the same item eg iphone/youtube. Now go to your iphone and use your primary google email for the username and the 16 digit code for password (include the spaces.) Now you should be able to log in and the next time you log in you might have to do it again and after that you can log in the way you do for youtube.

IMac won't connect to the to the wireless network and internet when a laptop is connected

When a windows laptop is connected wirelessly to my router and the internet my Imac won't connect. If the Imac is connected wirelessly first it turns off when I connect the laptop. the iMac has once given me a message about the laptop using the same IP address. Can anyine help, I have been putting up with this for a year now and it's a real pain. Any help appreciated Many thanks
Joel

Check the company that you get your internet service from. High speed internet through a phone service modem allows for one connection as the modem is controlling the IP addresses. If you add a wireless to this connection, your modem will still allow for only one connection at a time. The wireless modem should be "in charge". Call the internet service provider and see if they will walk you through how to give permission to your wireless to assign IP addresses and not the modem they supplied.
If your Mac and PC both want the same address, you can tell your Mac to use a manual IP address. Go to:
system preferences/network
write down the IP address, subnet mask, and router numbers. On dropdown Configure IPv4 choose "using DHCP with manual address". Now put back in all the numbers you wrote down except in the IP address box, change the last digit to a higher or lower number.
Now the PC will be happy with the IP it chose and the Mac will, also.

IPhone no longer connects to iTunes via Wifi

On July 1,12 my iTunes did an automatic update. After the computer restarting and I entered iTunes and the following messages appeared:
Message 1: Must reinstall itunes to connect to ipod or mobile devices.
Message 2: CD/DVD folder must be located in itunes folder in order to use with itunes
I have 2 iphones (both 4s, bought at same time, both running iOS 5.1.1)and one will briefly connect to itunes via Wifi (I will identify this one as iphone1) but the other one will not (I will identify this one as iphone2). I have a PC with Windows 7.
When iphone1 is connected to itunes via wifi is disconnects randomly. Under: Summary > Version, it has the message: Connect this iphone using a USB cable in order to update or restore its software. When I have it connected with the USB cable, there are no problems. The settings selected under: Summary > Options > are: Open iTunes when this iphone is connected, Sync with this iphone over Wi-Fi, & Manually manage music and videos. The Setting under Backup > Back up to this computer (where it backs up to; I do not know)
iphone2 does not connect via Wifi but used to. It connects without issues with the USB. The Settings in iTunes > Summary are the same as iphone2 except that iphone2 is set as Backup > Back up to iCloud.
My iphone2 is my primary device. I use it exclusively; for music, taking photos, syncing photos to my Photo Stream folder on my PC, etc. The iphone1 is my spouse's secondary phone, so its not used as often (ie: only has 4 songs downloaded, used to take the odd picture, has a mirror image of apps from iphone2).
I searched Apple Support and tried the following solutions that didn't solve this problem:
How to restart the Apple Mobile Device Service (AMDS) on Windows (support.apple.com/kb/TS1567) &
Set the Apple Mobile Device Service Startup type to Automatic
I have not done this: Remove and reinstall iTunes and AMDS. I did goto the: iTunes for Windows: Device Connectivity Tests > iOS > iPhone - iTunes Troubleshooting Assistantand into iTunes > Help > Run Diagnostics. The results were: All tests passed. (My iphone2 was plugged in with USB. The iphone1 was connected via WiFi.)
What do I do now? Do I need to remove and reinstall iTunes? and if so will I lose all my itunes info (videos, music, apps, settings) or will it just show up after I install iTunes?

Hi Mitch,
It sounds like you have already done many of the steps, but I would like you to look at this article -
iOS: Device not recognized in iTunes for Windows

and go over any that you may have missed.
Thanks for using Apple Support Communities.

When you use the Airport utility what happens?
What is in the System Preferences control panel for Network settings?
http://www.apple.com/support/airport - there is a forum just for Airport Community
Airport Express FAQ

Wi-Fi Setup Considerations
Things to consider before you begin
Start with a plan for the physical layout. Depending on whether you have an existing Wi-Fi network, or if you are using your AirPort Express as a standalone Wi-Fi device, there are several options available for you to choose from.
When using Ethernet, Cat6 cable is recommended.
The layout you choose should take into account environmental factors such as physical access, location, range, radio frequency interference, etc.
You will need to consider what AirPort Utility settings to adopt.
You will need to know whether you are using an AirPort Express (802.11b/g) or an AirPort Express (802.11a/b/g/n).
If you will be using more than one Wi-Fi base station, it may be helpful to read the article Extending the range of your wireless network by adding additional Wi-Fi base stations.
