Can I do the router uses an older Protocol of WIFI (WEP) with Lion?

A colleague who I am to help got a new router, which wwas pre configured by the provider.

Lions (Lions of Montain) on MacBook Air can connect to the Internet easily around my iOS 9 mobile (personal "hot spot").

My 9 immediately connected iOS devices.   Although older OSX (Lion? ML?, I don't know with certainty at this time) does not work.

They see the net in the most convenient airport and can fill in the PW and the 'antennas' in the menu shows good connection, although Mail and Safari (only available applications) report: no connection to the Internet.

Perhaps the kind of connection is newer legacy systems can in itself.

Can I do the router uses an older Protocol of the WIFI (WEP) with Lion on Airport?

This will not change anything, except less secure your network.  The encryption method does not affect the rest of the internet connections, and you indicate that you are connected to WiFi.

You can check if you have a valid DNS address

System-> network-> advanced-> DNS preferences

You can test your own DNS addresses by clicking on the [+] sign and adding something like

OpenDNS.org

208.67.222.222

208.67.220.220

Google DNS

8.8.8.8

8.8.4.4

You could try running "Network Diagnostics".

Finder-> go-> go to folder->/System/Library/CoreServices

This should open a folder

Double click on-> Network Diagnostics

Follow the instructions.

    How can I make the best use of a new external hard drive and a new catalog full of photos just loaded into Photoshop elements 14 Organizer?

    Keep all the files on external hard drive image?  Nothing else and no pictures on the desktop?

    Keep all image files both places?

    What is the best way to go through thousands of images in the Organizer to identify and place them in files?

    Once I've placed a file, I just leave it in the entire catalog or a way indicate to me that it has been sorted?

    As overwhelming, any tips/shortcuts/schemes, you can offer are welcome!

    As I only have the version of the EP, here is some info on the organiser:

    https://helpx.Adobe.com/Photoshop-elements/how-to/use-elements-Organizer.html

    Independent of how this feature works, you want to have your photos in one place and have a backup (second copy) somewhere else. All hard drives will not be successful at some point - some more early, some late - never trust to have your files in any safety devices if they are on a single disc. Once you have your sorted, it would be useful that you will organize/name/tag new photos immediately if the task is relatively short and simple. I copy my photos on my internal hard drive for my camera, take a quick look with preview to see who needs some changes and then decide where to put them - either drop them immediately after naming them or bring in an editing application and then file them away.

  • Configure the router Cisco E2000 wireless for my laptop HP with Vista, I can't work.

    Configure the router Cisco E2000 wireless for my laptop HP with Vista, I can't work.  I spoke with Cisco and they said that my Atheros AR5007 adapter does not work with Cisco E2000 and contact my computer vendor

    Hello

    HM... I guess that the Cisco people know what they're taking everything. The AR5005 is a b/g card and there should be a good reason to not work with a router that is able (the E2000 is able g) g.

    This is HP drivers for the card, http://h10025.www1.hp.com/ewfrf/wc/softwareDownloadIndex?cc=us&lc=en&dlc=en&softwareitem=ob-55737-1

    If you can't make it work, you must decide between a new card or another router.

    Personally, if it's new and I could return it, I'd get a different router model. But YMMV

    Bubble icons are the widgets corner. You can drag inward to round the corner. They are not part of your problem. If you want to hide them, select view > hide corner Widget. I have a hotkey defined for this menu item.

    If you see multiple bullseyes, you may have your set with the shape selected, that would prevent you from being able to move individual anchor points. Deselect the shape first, and then move the anchor with the direct Selection tool.

  • How can I do the download using firefox on my android phone?

    Sometimes I'm in the House of my brother and I use his wifi router to connect to the internet but I can't do the regular downloads. For example: I wanted to download the desktop version of firefox on my phone just to buy some time, but I can't get it.

    Check with the company that made your phone. Some Android phones may activate the "USB mass storage Mode" when you plug it into your computer. When you do this, you can browse the files on the phone and copy things to your computer.
