What happens if the controller fails?

Hello

It is a fundamental issue. What happens if wireless controller (4404) fails? All APs will be going down too, or only new users will not access not the wireless network?

TIA

Alex

It's really one depends on these issues.  If of the AP is in local mode and it is not all the other controllers available to join then the AP will go down.  If there are other controllers available as the AP could join then it move to that controller and the failure would be the process of discovery/join.

The other option is to have the AP mode H-REAP.  When the AP is in REAP hour mode they will be keep blowing along the same when the controller is down.  There are some limitations here of course, but given that the data of the customer traffic is enabled locally at the fire AP can still flow if the controller is down.

    What happened to the feature to get around on the artboard by pressing the space bar and dragging with the mouse?

    cwalker,

    If it does not, it may be time for the list:

    Sometimes, (some) things may fail or stop working for no apparent reason. When (other) possible reasons/remedies do not work, it is perhaps a kind corruption (temporary or permanent), or even preference settings which disturbs, which can be cured with something on the following list put in place in order to provide a catch-all solution for otherwise intractable cases. It starts with a few easy suggestions and safe) 1 and 2) for cases less serious and goes two ways 3) and 4) to reset the default preferences (easily but irreversibly and more laboriously but more completely and also reversible), then follows a list 5) various other possibilities, and it ends with a complete reinstallation 6). If no other suggestion doesn't work, or if no other suggestion appears, you can start on the list and decide how to go or who can apply.

    The following is a general list of things, try when

    (A) the question is not in a specific file,

    (B) you have a printer installed, connected and turned on if it's a physical printer (you can use Adobe PDF/Acrobat Distiller as a printer by default without the need to have a printer on, of course you will need to specify when you really need print on paper), and

    (C) It is not caused by problems with opening a file from external media (see below).

    You tried/made some of them already; 1 and 2) are easier for temporary strangenesses and 3) and 4) specifically may be corrupted/inconvenient preferences); ((5) is a list in itself and 6) is the last resort.

    If possible / there is, you must record a current work first, of course.

    (1) close Illy and open again.

    (2) restart the computer (you can make up at least 5 times);

    (3) close Illy and press Ctrl + Alt + Shift / Cmd + Option + shift during startup (easy, but irreversible);

    4) move the folder (follow the link with this name) with closed Illy (more tedious but also more thorough and reversible), for CS3 - CC you can find the file here:

    https://helpx.Adobe.com/Illustrator/KB/preference-file-location-Illustrator.html

    5 look through and try the relevant among the other options (click on the link with that name, item 7) is a list of the usual suspects among other applications which can disturb and confuse Illy, point 15) applies to the maybe CS5, CS6 and CC);

    Even worse, you can:

    6 (A) uninstall (check the box to delete the preferences, if any), B) run the cleanup tool (if you have CS3/CS4/CS5/CS6/CC) and C) reinstall. It is important to use this step three way: otherwise, things may persist.

  • What happened to the insertion function. It was on the same line as file

    What happened to the insertion function? It was on the same line as the files, tools, etc. He's gone. If you want to insert a jpg you sent as an attachment. I have read through the help files and that you can't find the answer. I want my old Thunderbird back! Newer is not always better.

    I suspect that you have lost the Mail composition toolbar. Open an entry window, press and hold the < alt > key, type v and check the box for the mail toolbar. I would also allow the Menu bar while you are there.

    Another possibility, if the Insert option is missing in the mail toolbar, is that it is spent in composition in plain text mode. Open the settings page of the account assigned by right-clicking on the account in the left pane, select Composition & addressing and tick the box labelled "Dial using the HTML format".
