Socket options to support hand off across wireless networks
Hello,
I'm developing an application client which connects to a server and is meant to run on PCs. I want to make sure that my client application doesn't disconnect when the user moves from one network to another network (one cafe to another cafe).
Is there any socket option to support this kind of client application requirements?

This nonsense is frequently encountered in newspapers and magazines, but I'm surprised to see it repeated here. Tim Berners-Lee is not an inventor or co-inventor of any Internet protocols except HTTP, which follows exactly the same principles as FTP, SMTP, etc: very tolerant line-oriented headers, and MIME-encoded data. These principles, not to mention the Internet protocols proper like IP, ICMP, UDP, TCP, etc., were invented by people like Vincent Cerf, decades before Berners-Lee had anything to do with it. Have a look at the authors and the dates on the RFCs. Berners-Lee is also credited with 'inventing' HTML which is a mild reworking of IBM SGML.:-) I stand corrected.

I've just upgraded to Yosemite and wanted to run the hands off option but my iphone 4s with ios8 doesnt give me an option to turn hands off on.
CheersOnly for Phone calls. Your Mac would also need to have Bluetooth 4.0 as well
(from: Connect your iPhone, iPad, iPod touch, and Mac using Continuity)
To use Handoff, you need two or more of these Apple products:
iPhone 5, iPhone 5c, iPhone 5s, iPhone 6, iPhone 6 Plus
iPhone 4s (sharing iPhone calls only)
iPad (4th generation), iPad Air
iPad mini, iPad mini with Retina display
iPod touch (5th generation)
These devices must use iOS 8 or later. -
Network Extender Dropping Calls when handing off to Outdoor Network
If I stand right next to my network extender, it works great. the moment I move outside a 15 ft ring, I begin to drop calls. i believe it is because my Blackberry is now getting a stronger signal from the outdoor network and I should be handing off to outdoor network. Instead of the call continuing, it drops. Also, the same thing happens when I am on a call inside my house, get into my car and drive away; I drop the call. I have called VZW Tech support and was told to power down the unit, yadda, yadda, yadda and call back if I still have the problem. Well, I still have the problem, so I am posting this in the hope someone has seen this and it saves me the hour long support call that doesn't resolve my issue...
I have the exact same problem with a Verizon/Samsung network extender that started dropping calls after about 30 seconds into a conversation. This problem started at almost the exact same time as those reported on this forum. Verizon has not once mentioned that it may be a problem on their end and we quit using the extender almost a year ago. However, with new smart phones in the household and multiple reception problems, we need to find a solution. I think Verizon owes its customers/supporters a solution since it sold the extender devices to the consumers at substantial expense. I for one, would like to either get my money back along with the time spent trying to rectify the problem, or get a solution that will allow us to carry on conversations in our home. It is ridiculous with the amount of money spent on monthly Verizon Phone bills, that we get such poor service - simply ridiculous!

Is it possible to turn off the wireless networking feature?
As I don't want to have a wireless hotspot 24/7 at my place and would prefer to conserve power when that function isn't needed, I'd like to know if the Time Capsules allow users to turn the wi-fi broadcasting on and off. Or is it just an always-on kind of machine?
"Do you mean simply connected via firewire or USB?"
You would need to have your computer connected to the Time Capsule via Ethernet.
"But, is there no way to save your original settings so they needn't be re-entered when re-starting wireless?"
No, this is not possible. When you change the wireless settings to "None" from "Create a Wireless Network" using Airport Utility, the Time Capsule requires an update and restart for the new setting(s) to take effect. The old setting is lost. Same thing when you change from "None" to "Create a Wireless Network" -
Airport error when attempting to import photos across wireless network
Hi,
I'm using the latest version of iPhoto '09 on a MacBook that's connected to my home wireless network through an Airport Extreme. Also on the same network is a brand new Mac Mini. When I attempt to import photos into iPhoto '09 on my MacBook from the Mac Mini, I get an Airport connection error that I dismiss by clicking OK. Immediately after clicking ok, I then get a "Can't find the original photo..." error and I hit cancel. I do this three times and presto the photo imports itself. This occurs every time I attempt to do an import.
My network is not dropping. My Internet connection is not dropping. My MacBook and the Mac Mini stay connected continuously so I'm not sure why I get these errors.
Any thoughts?
Thanks,
MarkIt has nothing to do with the Airport connection.
This sometimes occurs if you’re importing a file into iPhoto and there’s already a file there with the same name. Digital cameras can produce many, many files with the same name over their lifetime, so it’s not uncommon to have several files called IMG_00543.JPG, for instance. Now you want to import one also called this.
What happens is that iPhoto compares the two files to check for duplicates. However, if iPhoto cannot find the file already in the database for comparison, then you get this message. It suggests that your database is damaged because iPhoto has lost track of this (or these) similarly named files.
A simple test is to rename the file you are importing - just add a character - IMG_00543a.JPG for instance. If this then imports with no issue then you might consider rebuilding your library:
Download iPhoto Library Manager and use its rebuild function. This will create a new library based on data in the albumdata.xml file. Not everything will be brought over - no slideshows, books or calendars, for instance - but it should get all your albums and keywords back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one.

Group Policy to disable ability to turn off wireless networking in Windows 8.1 Update
I am wanting to disable the ability to turn off wireless networking in our Windows 8.1 Update clients using Group Policy. We are a school that runs classroom management software enabling the teachers to view what the students have on their screens.
Students just switch off their wireless to avoid detection. I have searched the Group Policy listings and can't find anything.
Thanks.Hi GeoffAUS,
I can’t find a direct group policy to disable the users’ ability to turn off the wireless network in Windows 8.1.
If we just disable the display of wireless connection, we will need to additionally disable the ability that disabling the driver in device manager.
We could try the workaround to use UAC to control the wireless connection.
Go to Computer Configuration->Windows Settings->Security Settings->Local Policy->Security Options, and set the option
User Account Control: Behavior of the elevation prompt for standard users.
Please make sure the computer automatically connect to Wireless.
For more information, please refer to the following article.

No Join a Wireless Network option
Using the AirPort Utility and going into one of my Airport Extremes, under the Wireless tab in the Wireless Mode option there is no Join a Wireless Network option. Only Extend a wireless network, create a wireless network, and off. I have other Airport Extremes and they are working fine.
Thanks.Try holding down the "option" key on your Mac while you click on the Wireless Mode selection box.

Time capsule, joined wireless network, no internet on LAN sockets
I have a problem, no internet access from the ethernet sockets on the Time Capsule.
Here is my set-up:
I have a new wireless router from BT in the UK. A BT Home Hub 2.
This provides my internet access and a wireless network fine.
I have my TC connected to the wireless network using "join an existing wireless network".
I cannot reach the BT router to plug in an ethernet to the TC so need a wireless connection.
All is working fine, backing up etc....
But, If I plug into the ethernet sockets on the back of the TC I cannot connect to the internet.
I think the TC is using DHCP.
Anything I plug in cannot access the internet.
Is this a problem with the set-up I have made perhaps, as I have previously used the ethernet sockets when the TC was extending a wireless network in my past home and it worked fine, but I had an AEBS as the wireless router and a simple modem connected to the AEBS via ethernet.
So the only difference is the TC is joining a wireless network instead of extending one.
TC cannot extend the wireless network of the BT Home Hub 2.
Is there a way around this does anyone know?
Thanks in advance!
Gary.Welcome to the discussion area, Gary!
I have a problem, no internet access from the ethernet sockets on the Time Capsule.
When the Time Capsule "joins" a wireless network, the routing functions within the device are disabled, so there is no signal present at the ethernet ports. In this type of configuration, the Time Capsule becomes in effect, simply a wireless backup device.
If you need to enable the ethernet ports on the Time Capsule on your network, your only option is to connect the Time Capsule to your main router using an ethernet connection. If it's not possible to run the cable, you might want to take a look at a pair of ethernet powerline adapters to accomplish the same task by using the AC wiring in your home to transmit the signal.

IChat knocks off my wireless Airport connection on video chat
iChat on my MBP was working until Leopard. Now, every time I start a video chat with someone as soon as the connection is made it knocks my off my wireless network and I must go back in Airport and reconnect to the network. This happens every single time I try it and it's very strange. Any ideas? I have internet sharing off and the firewall on the MBP set to allow incoming connections, but it knocks me off no matter who starts the video connection, me or them.
Does it work if the Airport is not on the LAN ?

I searched adn tried the Linksys FAQ to no avail to get an answer to the subject question.
Is there any way to verify who is actually using or trying to attempt use of your wireless network, if so, where do I locate and view this information?
I just set up a wireless system so my wife could get access from her wireless equipped laptop, but I really see no area to verify who is actually using the wireless network or if some other outside source/person is attempting to get access.
Any info on where, how and what to do to view this type of info would be greatly appreciated and if it can't be, shouldn't there be something added to the system that would allow one to view all users accessing their wireless system?
Thank you,
Clay FugitteTracking down who is using your wireless system is usually difficult or impossible. The router only knows the MAC address of the connecting computer. MAC addresses can be faked. Even if you knew the MAC address of the person connecting, what can you do with that info? Go around the neighborhood asking people "Is this your MAC address?"
Instead of worrying about who is connecting to your wireless, you should simply set up wireless security. This will keep intruders off your wireless network. Then you don't need to worry about who is connecting.
It sounds like you are running an unsecured wireless router. When you run an unsecured wireless router, anyone within range can login and use your Internet connection. At a minumum, this means that they will be using your bandwidth. At worst, they could be uploading copyrighted music, sending spam email, distributing viruses, or downloading child pornography --- all from an account with your name on it! So my advice is --- secure your wireless network.
To set up wireless security, do the following:
First of all, to setup wireless security, you must use a computer that is wired to the router.
Where to find the router settings: The router's login password is usually on one of the "Administration" pages. The other settings are all found in the "Wireless" section of the router's setup pages, located at 192.168.1.1
First, give your router a unique SSID. Don't use "linksys".
Make sure "SSID Broadcast" is set to "enabled".
Next, leave the router at its default settings (except for the unique SSID), and then use your pc to connect wirelessly to the router. Test your wireless Internet connection and make sure it is working correctly. You must have a properly working wireless connection before setting up wireless security.
To implement wireless security, you need to do one step at a time, then verify that you can still connect your wireless computer to the router.
Next, encrypt your wireless system using the highest level of encryption that all of your wireless devices will support. Common encryption methods are:
WEP - poor (see note below)
WPA (sometimes called PSK, or WPA with TKIP) - good
WPA2 (sometimes called PSK2, or WPA with AES) - best
WPA and WPA2 sometimes come in versions of "personal" and "enterprise". Most home users should use "personal". Also, if you have a choice between AES and TKIP, and your wireless equipment is capable of both, choose AES. With any encryption method, you will need to supply a key (sometimes called a "password" ).
The wireless devices (computers, printers, etc.) that you have will need to be set up with the SSID, encryption method, and key that matches what you entered in the router.
Retest your system and verify that your wireless Internet connection is still working correctly.
And don't forget to give your router a new login password.
Picking Passwords (keys): You should never use a dictionary word as a password. If you use a dictionary word as a password, even WPA2 can be cracked in a few minutes. When you pick your login password and encryption key (or password or passphrase) you should use a random combination of capital letters, small letters, and numbers, but no spaces. A login password, should be 12 characters or more. WPA and WPA2 passwords should be at least 24 characters. Note: Your key, password, or passphrase must not have any spaces in it.
Most home users should have their routers set so that "remote management" of the router is disabled. If you must have this option enabled, then your login password must be increased to a minumum of 24 random characters.
One additional issue is that Windows XP requires a patch to run WPA2. Go to Microsoft Knowledge base, article ID=893357 and it will direct you to the patch.
Sadly, the patch is not part of the automatic Windows XP updates, so lots of people are missing the patch.
Note:
WEP is no longer recommended. The FBI has demonstrated that WEP can be cracked in just a few minutes using software tools that are readily available over the Internet. Even a long random character password will not protect you with WEP. You should be using WPA or preferably WPA2 encryption. -
Strange - Home wireless network ok, no access Public networks
Ok, I'm not getting this, and I've been around computers for some time.
Got my B570 'round September last year. Worked great on home wireless network ( Brighthouse networks in Florida, with Ubee Wireless modem running Lightning or 40mb.)
Had to move to new place offering a house offering of wifi, had a bear getting that up, but finally did.
Here's the q, and I've seen this on an HP laptop running Vista, but that one died and I got this one.
Go to Starbucks, Panera's, Dennys or just about any other public place, and I can see the routers and even connect, but can't get anywhere on the internet. I get either a limited or no internet, or identifying, but that's it. I know that their router is working because i can make the wifi connection on my phone and browse no problem, and I see other patrons with different computers logged in at the same time.
McDonalds, I can get in, and soon as the network connection comes up, browser will pop up and allow me to accept McD's access rights page and I can connect. I know that Denny's has one too, but it doesnt pop up, and ( I know that this will sometimes happen too ) if I try to connect to a website, sometimes the local accept page will pop up, but usually not for me.
I have Google Chrome as my primary web browser, but even if I try to bring up via IE, no go.
I can connect to the internet via my droid phone usb wired or just wireless, but don't like that to be a regular solution.
I've already tried to update the wireless driver ( Broadcomm ), but computer tells me that i'm up to date. Enabled then re enabled. Flush DNS didn't help either, ipconfig / release and renew didn't do it either. Using Comodo Internet Security, and turned it off, even exited out of program and that didn't help either.
Today was an interesting day. went to Denny's thinking I'd get some work done, and couldn't get logged in. Went to Fedex Store to get some printing done, and logged in right away. Came home and can log into the communities public ( fee based ) network and can log right in. Looked in my bag and found a usb wifi dongle I had used for the HP when the wifi on it died out, but didn't try that yet. I'd rather not, I'd rather find out why the wifi on this laptop seems to be finiky with who's networks I'm using.
Any ideas would be appreciated.

The issue you're facing is a very strange issue. From what i gather ist begging to choose the network it wants to work with. I may need more time to look inot his to see if it is a harware issue. But i would like to try something though. You may want to uncheck the IPV6 in ur Wireless network properties.
To do that you will have to go to your "Network sharing centre" > Click on "Change adapter settings" on the left hand panel > Highlight "Wireless network Connection" > Right Click "Wireless network Connection" and select on "Properties". Be sure to uncheck the "Internet protocol version 6 (TCP/IPV6)". Then click on and try to reconnect.
Let me know how it goes..

How do I make my wireless network undiscoverable?
That's pretty much the question. I just got done setting up my new Airport Extreme base station (802.11n) and now I would like the wireless network to be undiscoverable.
Message was edited by: WoojUnfortunately that does not make it undiscoverable. The network name is still broadcast between the base station and any connected clients. Therefore anyone can learn your network name in the matter of a second or two. The only thing that enabling this setting frequently accomplishes is complicating the life of authorized users.
The ONLY ways to make it undiscoverable is to (a) power off/unplug the base station or (b) configure it so that the power level is zero. Either option means that there is no wireless network. -
HP 3520 All-in-One Printer Falls Out of Wireless Network Periodicia​lly
We have an ongoing problem with our HP 3520 All-in-One Printer. We set it up for wireless printing and it works....for a while. Periodically, we find that it falls off the wireless network and will not print except when plugged into the USB cable. The problem is that my husband has an Ipad Air as his main device which he cannot plug into the printer and needs to have wireless working...and the main reason we bought this printer was to have wireless capability. We *think* that it may be falling off the network when we have a brief power outage or Internet outage, which happens occassionally for a short time. Also, on my laptop, although the wireless set-up to this printer has worked in the past, now I see that I can either connect my laptop to the Internet network OR the printer, but not both at the same time. How strange is that?
I have printed out the Wireless Network Test Results AND the HP Network Configuration Page, in case that information can be useful as we attempt to troubleshoot this problem.
Note that the printer is no longer under warranty.
I have reviewed numerous HP product support pages and feel as if I am running in circles. The help information is confusing to us and we have spent so many hours trying to troubleshoot this issue that my husband has completely given up on that printer and I am doing my best to try to save it since it is only about a year old.
We appreciate any help you can give us to remedy this ongoing problem.
PSCoHello there PSCo, Welcome to the Forums! I hope you enjoy your experience
I saw your post about your Deskjet 3520 dropping the network connection. It very well could happen if the power goes out or Internet disconnects. I have found a troubleshooting guide that is geared to help repair the wireless connection disconnecting. It will go further into detail about the causes and things to do to help.
I hope the steps work for you!

Can't see AE when connecting to a wireless network
Hi there,
I'm having problems joining my AE to an existing wireless network. I've configured the AE using the Airport Setup Assistant (I chose the 'setup new base station' option, and then 'connect to current wireless network'). The AE is glowing solid green. But, I can't see it at all in my Airport Admin Utility, or in the Airport status icon in my menu bar.
Can anyone suggest what I should do?
iBook Mac OS X (10.4.5)Sorry for a tardy reply but I've been out of the country. I'm a very basic guy so whenever I have experienced anything similar to your situation, I go to the beginning. I hard reset the ae, run it through setup assistant (vs. admin.) tell it I want to join the existing network enabling iTunes, naming the unit, etc. The only difference in what it sounds like you're doing and what I did was enable the unit to act as a WDS remote (I wanted to extend my range) feeding from the base. it sounds as though the unit can be seen but it is stretched for range. If you elect to do the hard reset, move your ax as close as reasonable to your existing base. After you have done the setup, the light will turn green, then flash amber (twice as I remember) and turn solid green again. You can then unplug it and move it where you need it. I am running three units to three stereos and the furtherest is about ninety feet away with multiple walls. It feeds off the closest ae which is only about thirty feet and the whole thing works as an all select or single select system with iTunes. I have airfoil from rogue amoeba but I have not found it to be as reliable in broadcasting to mutiple units as iTunes. Try it again (I hate to ask) and let us know.

Unable to reconnect to wireless network after closing lid on macbook pro
After installing recent software updates, I am unable to reconnect to my wireless network when I close the lid on my macbook. It says that it is "connected", but I can't access any website, check e-mail or ping any external server.
I've never had a problem before, but now that I've installed software updates in the past few weeks I noticed the problem.
Anyone have any ideas?
MacBook Pro (Intel) Mac OS X (10.4.9)which ultimately means apple didn't do enough testing before releasing the last patch
This is not always, and may not be, the case. What many don't realise is that many 3rd party developers stray from the 802.11 series specifications in an attampt to boost speed and get one up on their competitors. For instance D-Link, amongst others, use a short preamble setting by default in some of their routers to improve performance. However, this is non-standard and when it comes across wireless network adapters that don't support this then you have problems. They assume that their network adapters are being used for "maximum speed and compatibility". Whether Apple should or should not support a short preamble is another subject altogether.
However, I do agree with you in that Apple should put more work into their Airport software.
