well in USB mode, but in WLAN catastrophic! - Real design flaw

+ Very good scans,
+ Good usability of software for PC and iOS, fits very well with our purposes (dropping on the network drive, but above all direct shipment to Evernote).
But Minus: Massive construction and design errors and quasi unavailability of normal wireless mode.
What a fact no one does not explain thoroughly, especially the manual:
You can operate the unit in three different modes:
1. USB (clear)
2. by the unit builds its own Wi-Fi, in the logging in
3. as a WLAN client in an existing network.
USB works (with Mac OSX) immediately.
The Access Point mode, the default and works well. The disadvantage is that you then with his PC or iPad to scan must change the WLAN and then back - fiddly, awkward, and you have the time do not have Internet access.
So I hope that you include the device into existing wireless - and was bitterst disappointed.
1. Installation is to say the least, disastrous. There are, as I said, yes three modes of the device. But the device itself can only change between USB and WLAN. But then comes the only og Access Point mode, and the manual promised, simple method method of connection to the router using WPS button does not work, because they can not work, yes. One has the wireless mode namely change only, but nowhere setht how that goes. I had to zusammeklauben laboriously from Internet forums:
Connect yourself via wireless directly to the device and load the browser, its configuration page (the URL you have to find out first time: [...]). There you have to also sign, with nowhere the data are (ie user: root (password: blank) - only then you can switch between the access point and station grrr now works also connect to the own router at home really quite simple with.. the WPS method.
Dear people of Canon when you mitlest here: Why there is no third switch position to switch between USB, Access Points and WLAN integration? Why ever there is no front LED that indicates which mode is active? Because if Wi-Fi is on, no matter which of the two wireless modes, USB is completely ignored - but the active Wi-Fi is only displayed on the back - not well thought out!
2. But the won wireless connection was then very disappointing, because the scanner is on the network simply grottig slowly. Just go in the lowest resolution the leaves afloat through the device. If you set 300 dpi or more, increase everything and takes quite long. In addition, the scanner needs on power for some time, until he has logged into the WLAN and the PC is available - in everyday life do not really fit.
Conclusion: We reserve the unit and still use the wireless mode only occasionally, if we want to scan directly into the iPad into. Then the somewhat cumbersome Access Point mode is used to connect the iPad directly.
The normal case will be, though, that you scanned by computer and in any case sits with the laptop on the desk level equal to the scanner. The USB cable (with all kinds of peripheral devices to the hub) is then inserted completely nimble, and the scans go liquid going.
