Mailing fails over WiFi

28 08 2015

Given that all settings of your mail accounts are correct it might happen that your iOS device cannot receive or send mails although it connects successfully to the Internet.

I experienced this issue today on my iPhone 4S running on iOS 8.4.1 although this update was already installed weeks ago.
The following steps solved the problem but I cannot exclude that it will return.
 

1 Go to

Settings – Privacy – Location Services – System Services

and deactivate Wi-Fi Networking.
 

Go to 

Settings – General – Reset

and tap on Reset Network Settings.

  
Mailing should work properly now. For me it worked also after re-activating Wi-Fi Networking. Strange, isn’t it?
 

Notes …
 

Wi-Fi Networking …

If Location Services is on, your device will periodically send the geo-tagged locations of nearby Wi-Fi hotspots and cell towers in an anonymous and encrypted form to Apple to augment Apple’s crowd-sourced database of Wi-Fi hotspot and cell tower locations.
 

Reset Network Settings …

Maybe the problem already can be fixed with just turning off Wi-Fi Networking. If not you must reset the network settings which means that credentials to join networks are deleted from your device’s memory. Onetime you must manually choose a Wi-Fi network and enter the credentials.

Dear Apple devs

it’s annoying to be faced with Wi-Fi issues since years. I hope we will see a *final fix* in iOS 9. If not I will ask Siri to stop working for you. She already told me “OK, maybe not.”. It’s antediluvian to periodically refill an iThing with fresh settings.

AiO Remote by Hewlett Packard

24 03 2014

Printing documents seems to be old-fashioned in the modern era of digital communication. But occasionally printouts of documents are necessary. I for example use it for if I have to look on two or more documents to compare the contents which is pretty uncomfortable on an iPad because of the One-Window-Technique.

AirPrint

Apple is known for simple and user-friendly solutions.
In cooperation with Hewlett Packard the company developed the AirPrint technology.

AirPrint is a feature which is implemented in Apple products starting with OS X Lion and iOS 4.2 in November 2010, for printing using a wireless LAN, either directly to any AirPrint compatible printers (such as HP’s entire ePrint range, Brother, Canon, Dell, Epson, Gestetner, Hewlett-Packard, Infotec , Lanier, Lenovo, Lexmark, Ricoh, Samsung, Savin, Xerox and more) or to non-compatible printers through a MS Windows, Apple Mac OS X, or GNU/Linux PC. AirPrint does not require printer-specific drivers.

The current list of AirPrint compatible printers (at the time more than 1000) can be found on

Apple Support HT 4356

Manufacturers supporting AirPrint with their printer products are

Brother, Canon, Dell, EPSON, Fuji Xerox, Gestetner,
Hewlett Packard with 95 Printers
Infotec, Kyocera, Lanier, Lenovo, Lexmark, NRG, NTT, Oki Data, Olivetti, RICOH, Samsung, Savin, Sharp, TA Triumph-Adler/UTAX, Toshiba, Xerox, Zink

A number of software solutions allow for non AirPrint printers to be used with iOS devices. For such printers, AirPrint support can be achieved by configuring such support on an intermediary system already having such printers configured for local printing, shared on the same network. Since AirPrint is driverless, such a configuration compensates for the lack of native AirPrint support by using the drivers on the intermediary system instead.

Note
The simplest solution for all platforms is to create a new Bonjour Service that tricks iOS clients into believing they’re talking to an AirPrint device.
Presto by Collobos Software Inc. is an example for such a desktop application which allows printing from iOS devices to every printer connected to the same network.

Bonjour is Apple’s implementation of Zero-configuration networking (Zeroconf), a group of technologies that includes service discovery, address assignment, and hostname resolution. Bonjour locates devices such as printers, other computers, and the services that those devices offer on a local network using multicast Domain Name System (mDNS) service records. Bonjour comes built-in with Apple’s OS X and iOS operating systems. Bonjour can also be installed onto computers running Microsoft Windows.

AirPrint in details …

My home configuration consists of an Apple Airport Extreme Router and an HP Photosmart 6510 which is AirPrint capable. That means the printer has just to be connected to the power supply. In a further step the connection to the WiFi network is established via the iPhone-like control panel by entering the networks password.

After connecting the printer to the WiFi network it appears in the print menu of every printing-capable app. No installation of drivers, no cables, no additional software which usually comes from an installation CD and is nothing more than ad of the manufacturer.

AiO Remote app by HP …

There are two ways to connect an iOS device to a HP printer:

  • 1 HP wireless direct allows you to connect your iPad directly to your printer wirelessly, without a wireless router. The printer must be equipped with HP wireless direct, and HP wireless direct must be turned on to connect to any iOS device.
  • 2 When connecting to the printer over a WiFi network, you are connecting to the printer using a wireless router. The printer might be wirelessly to the router or with an Ethernet cable. A connection is established after entering the WiFi password.
  • The features …

    • 1 Take a photo and automatically transform it into a PDF.
    • 2 Scan pages placed on the device by using the control buttons on the printer’s display or controls displayed in the app. Save scanned documents in the app specific folder on your iOS device or in the cloud (Google Drive, Dropbox, Box, Evernote, Photostream, or many other cloud storages like iDriveSync via WebDAV).
    • 3 Copy documents using the control buttons on the printer’s display or the controls shown in the app.
    • 4 Show printer details like settings, comnections, supply levels, and print reports like network configuration, wireless test report, or print quality report.
    • 5 Automatic upload of new documents to iCloud and syncing documents across all your iOS devices.
    • 6 As already mentioned AiO Remote can be connected to different cloud storages. So it’s also possible to download documents from there. They can be printed, saved locally, sent by mail, or transferred to other cloud storages.
      Unfortunately Apple’s iWork file formats are not supported.
    • 7 Optional usage of the HP ePrint Service which allows to send print jobs to an E-Mail address registered on the HP ePrint website. If the registration process is finished your printer gets an E-Mail address from HP. Print jobs can be sent to this address and the printout is done if the printer is turned on. So you can print documents from anywhere by sending an E-Mail to your printers E-Mail address. All these print jobs can be managed using the HP ePrint app or the HP ePrint website.
      The HP ePrint service can also be used to print documents on nearby HP ePrint centers e.g. hotels. Nearby centers are shown within the app if Apple’s location services are turned on.

    Document management …

    I summarized some features of the configuration by taking screenshots.

    3 Saving the scanned document to a cloud storage or mailing it

    Non-AirPrint capable printers …

    When people are evaluating mobile printing solutions, one of the options is to buy a new printer. If you already use a non-AirPrint capable printer it cannot receive print jobs from your iOS device. Presto (former name FingerPrint) by Collobos Software Inc. addresses this problem. The application finds your classical printers automatically and makes them available to your iOS devices if both, printer and iPhone or iPad, are in the same WiFi network.

    How to …
    Consider a network with an attached printer and an iOS-Device in the same network. Install Presto on a Mac or a PC connected to this network. For your iOS-Device no further action is needed that means no special app has to be installed.
    Presto finds all network attached printers automatically and they can be selected on the iOS-Device with the SELECT PRINTER dialog within every app which supports printing.

    See this video for a short description of Presto by Collobos.

    Summary …

    AiO Remote is a continuously updated app from a reliable developer with outstanding features. UI and UX are perfect and the iCloud integration lets you take photos of documents with your iPhone which already arrived when you come home and use your iPad for further actions.

Speed Test

25 08 2013

Nature with it’s electromagnetic waves traveling with the speed of light helps us to retrieve information from the internet pretty fast even if the way data is taking is by far not the shortest possible.

Using a link from within an app a website opens after about 3 sec including the opening of Safari browser. It’s quite fast compared to a bus, a car, a high speed train, or even an aircraft.

The speed of light …

If there is a cellular connection to the Internet data can be transmitted without using a medium in contrast to sound which needs the air or the earth to propagate and to transmit information like the cry ‘Help, help’.

Electromagnetic waves transfer data in vacuum at the speed of light. None of Apple’s innovative techniques can make it faster. It’s a law of nature (a universal physical constant) found out by

Ole Rømer first demonstrated in 1676 that light travelled at a finite speed (as opposed to instantaneously) by studying the apparent motion of Jupiter’s moon Io. In 1865, James Clerk Maxwell proposed that light was an electromagnetic wave, and therefore travelled at the speed c appearing in his theory of electromagnetism. In 1905, Albert Einstein postulated that the speed of light with respect to any inertial frame is independent of the motion of the light source, and explored the consequences of that postulate by deriving the special theory of relativity and showing that the parameter c had relevance outside of the context of light and electromagnetism. After centuries of increasingly precise measurements, in 1975 the speed of light was known to be 299,792,458 m/s with a measurement uncertainty of 4 parts per billion. In 1983, the metre was redefined in the International System of Units (SI) as the distance travelled by light in vacuum in 1/299,792,458 of a second. As a result, the numerical value of c in metres per second is now fixed exactly by the definition of the metre.

Within media like cables it’s slightly slower, about 90 km/second (324,000 km/h or 201,324 miles/h).

With the speed of light you would need

From geostationary sattelite to earth 119 ms
From Sun to Earth 8.3 min
Across the Milky Way 100,000 years

And from Cupertino (Apple’s Headquarter) to Cologne in Germany?
Well that’s a problem. The app Google Maps showed me neither the way nor the distance. But there is a more severe problem: Light propagates linear. So a light beam would’t go the way to Cologne.

Internet connection …

If you connect your device to the Internet data is transferred via a couple of stations.

With the app Nice Trace the way the data takes from source (the server where you get the data from) to destination (your iPhone or iPad) can be reported.

This is the way my website http://iNotes4You.com is transferred to my device.

My home configuration is a Cable Internet Connection from German provider UNITYMEDIA with a Cisco Modem and Apple’s router AirPort Extreme working on 802.11 a/b/g/n standard in the 5 GHz band. The device was an iPad 3rd Gen.

To eliminate ups and downs of the data transfer speed I measured the transfer rate for downloads under the following conditions:

50 repeated measurements
every day for one month at 8 am, 1 pm, and 9 pm

The apps used different test servers.

To compare the results I calculated the mean value of all measurements for each app.

Do the measured values come close to the everyday usage of your device with all the ups and downs of the internet connection?

Yes, they do.

Here is the result of using the app FTP Client PRO by Anders Havn with which I downloaded a file of 305 MB file size under the same conditions described above.

Here are mean values of all the results I took over a period of one month:

An alternate app …

If you are interested in an app which combines speed test with network analysis try

Net Analyzer by Jiri Techet

This perfect universal All-In-One app gives you all informations about a network including standard tools such as ping, traceroute, port scanner, whois, and beyond providing geolocation for all discovered servers.

Additionally I was impressed of Jiri’s perfect website for mobiles.

See this gallery to get an overview of the features:

Summary …

The results of all apps are within +-4.5 %. Differences may be caused by the different test servers used during measurements. All apps do what they are intended to do but cover just one functionality except Net Analyzer by Jiri Techet.
