Configurazione connessione ad internet wireless imac 21.5"

Come si configura la connessione ad internet wireless nell'imac 21.5" e un router dlink 2740b. Airport si connette al router ma non ho accesso ad internet. Aiuto!

First,
Completely uninstall Zeobit MacKeeper.
http://applehelpwriter.com/2011/09/21/how-to-uninstall-mackeeper-malware/
Second,
Uninstall Kromtech software per uninstall instructions on the Kromtech website.
Third,
Uninstall Trusteer Rapport per the uninstall instructions on the Trusteer website.
Fourth,
You have something called Antivirus installed on your Mac. If this is part of the Kromtech software, this MUST be uninstalled, also.
You need to update all of your third party software if there are OS X Mavericks updates that can be applied.
You may need to go the third party developers' websites if there are no updates through the Mac App Store.
Make sure all of your Web browser Internet plugins, extensions and add-ons are up to date, too!
Also, if you have any connected third party devices, like non- Apple keyboards, mice, drawing tablets, hubs, card readers, other digital devices and peripherals, etc, you need to update the drivers for these devices to OS X Mavericks compatible versions by going to each device maker's website and search for newer Mavericks software driver updates for each of the connected peripherals, if available and applicable.
After you completed all of this, restart your Mac.
Good Luck!

Can no longer connect to internet wirelessly with Linksys WRT54G...

Hi, all...
I'm at my father-in-law's house. His home network setup is as follows:
* Compaq desktop connected via Ethernet cable to
* Linksys WRT54G, v3 (IP 192.168.2.1) connected via Ethernet cable to
* Westell DSL modem provided by SouthEast Telephone (his ISP - IP 192.168.1.1)
I set this equipment up for him about 18 months ago. His Compaq desktop connects perfectly to the internet, using the setup I described above, which I set up for him about 18 months ago. I *used* to be able to connect to the internet wirelessly (with both my IBM ThinkPad and my MacBook; my bro-in-law *used* to be able to connect to the internet wireless (with his Dell laptop).
For reasons we don't yet understand, neither of us can connect wirelessly to the internet any longer. I have called Linksys, posted to their board, and read other threads here, so I am aware that MacBooks have some issues with Linksys routers. I'm getting ready to phone my father-in-law's ISP, to see if they can help.
But... I don't understand why this used to work, but doesn't any longer. I would be very grateful for any help any of you great folks could provide, and I will gladly post here any detailed info on the setup that might be of help!
Many thanks,
Bill J.

Thanks for your reply.
Actually the Linksys 2Wire modem works fine in OSX and when connecting via a Compaq PC I also have in the house. It is just on the MacBook running XP that it fails to "connect". XP see's the network but cannot connect.
Also, I downloaded again bootcamp and created a fresh driver CD, reinstalled the driver and received the same error: 1706 No valid source could be found for product Macintoish Drivers foir Windows XP.msi.
I looked at the directory on the CD and it appears that there are no driver files, only documentation.
I called Apple, got no help, called Microsoft, spent 1.5 hours talking to them
they were no help either.
I sent a messge to the bootcamp beta mail address informing them that it seems the drivers are not being downloaded with bootcamp.
Thx again.

WRT54GL unable to access wired shares or printer on PC from wireless iMac

The subject line applies to a new router on which I can access the internet ok both from the wired PC and the wireless iMac.
The problem is this router is unable to access the PC shares or printer from the iMac. Pls note, "this router"!
I have an identical WRT54GL v1.1, same firmware, setup is identical on both, one works with no problem, but the new one has the above problem..
I have spent a day on it and its in line for return on Monday, but I still hope for a miracle tip which may sort it out :-)
On the good one 'Port scan' of the PC from iMac gives me:
Port Scan has started ...
Port Scanning host: 192.168.1.100
Open TCP Port: 139
Open TCP Port: 445
while the faulty one gives me:
Port Scan has started ...
Port Scanning host: 192.168.1.100
..and thats it! No contact.
Yes, the router is set up for 'Lan & Wireless' (no way to change that setting to 'WAN only' it seems, it bounces back to 'Lan & Wireless')
I have btw done a Factory Reset on it (twice) with no joy.
Any ideas anyone?
Mvh

My first guess for this kind of problem would be a software firewall on the computer. The firewall will detect where it is connected and configures the settings depending on the location. Two routers are two different "locations". Try turning off the firewall or even better deinstall it as often some parts of those software firewalls are still active when turned off.
The only option that does affect access of wireless clients to the LAN is the "AP Isolation" option on the "Advanced Wireless Settings". That should be off.
Another thing you could try if you like: do a configuration backup on the working router and restore it to the faulty one. Maybe there are some settings that don't match and that you cannot configure through the web interface. Have you ever used a 3rd party firmware on either of the routers?

My PC can connect to the airport extreme but with encryption it cannot connect to the internet my iMac has no issues, any help.

My PC can connect to the new airport extreme I just purchased but with encryption it cannot connect to the internet my iMac has no issues. If I open the airport exteme up and provide no security everything is fine which leads me to believe it is something with the encryption between the two devices. Not sure what step I'm missing here this shouldn't be this difficult.

Sorry, I should have been more clear. I am asking if the DNS IP addresses, not the IP addresses assigned by the DHCP service, are the same. DNS is like the Internet's version of the Yellow Pages. Your ISP typically will provide them to you or you can elect to use those provided by another source, like OpenDNS.
DNS is the service that translates a website's URL to its actual IP address so that you can access it. I am just trying to rule out that the PC is not configured properly with the correct DNS IP information.
The other thing to check is if the PC is configured to use a Proxy service. By default, it would not be.
Finally, what is the make & model of the PC. More importantly, if the PC is using either a PCI or USB wireless adapter, what is its make & model?

New iMAC - want to connect PC Laptop to Internet via iMAC Airport

Hello - I have a new IMAC and the Internet connection to the IMAC is fine but I'm having trouble establishing a wireless network.
The store told me that I could use the Airport built into the MAC as a wireless router so that my PC laptop can access the Internet as well. My PC laptop is running Windows 2000 - and I have used it with a wireless router previously.
I can see the iMAC wireless network connection in my laptop's available network; however, I'm unable to connect to it.
Also, my IMAC system properties for Airport indicate that the wireless network is unavailable.
I've not selected any security settings - unless there's some default settings that I'm not aware of.
Advice or suggestions please???

The store told me that I could use the Airport built into the MAC as a wireless router so that my PC laptop can access the Internet as well.
That's correct. You will be using your Mac OS X's Internet Sharing feature to share your iMac's wired Internet connection wirelessly, using the iMac's AirPort, to your PC laptop. However, you will not be able to use wireless security, as the only option available (WEP), for Internet Sharing, will only work with other Macs.
To setup for Internet Sharing (Wired to Wireless):
Enable Software Firewall - iMac
System Preferences > Sharing > Firewall
- Click Stop to start the software firewall
Setup the Network
Cable Modem > (Ethernet cable) > [Ethernet port] iMac > (wireless) > PC laptop
Setup Port Order - iMac
System Preferences > Network > Show > Network Port Configurations
- Verify that "AirPort" and "Built-In Ethernet" are enabled.
- Verify that "Built-In Ethernet" is at the top of the list, followed by "AirPort".
- Click "Apply Now."
Configure the Internet Connection - iMac
System Preferences > Network > Show > Built-In Ethernet > TCP/IP
- Configure IPv4: Using DHCP
- Configure IPv6: Automatically or Off
Enable Internet Sharing - iMac
System Preferences > Sharing > Internet
- Share your connection from: Built-in Ethernet
- To computers using: AirPort (checked) (Note: Uncheck all other entries in the list.)
- AirPort Options
-- Network Name: <anything you want>
-- Channel: Automatic
-- Click OK
- Click Start

Issue in connecting to the internet wireless with my Linksys

OK. Here's the deal. I am entirely frustrated and also over my head trying to solve this on my own as I have no idea what I'm doing.
I have a Mac Powerbook, OS X (3.9). I have always connected to the internet wirelessly through my Linksys router (Wireless B Access Point, Model Wap 11).
I have recently moved and now use Comcast for my internet. When they installed my internet, I had not yet unpacked my wireless router, so I was set up to be connected via the actual cable plugged in. Now that the router is all set up, I cannot for the life of me get my wireless to work. Currently, I can use the internet wirelessly in other homes/school no problem. In those cases, I don't do anything, I just turn on my computer and it connects automatically. But for some reason in my apartment I cannot make it work.
I *think* the problem lies somewhere in the IP address area? If I look at my Airport settings and go to the TCP/IP tab, there is no information contained on the screen. Meaning, in the area where it says IP Address, Subnet Mask and Router, there is NO data listed, just gray empty space. The same goes for the DNS Servers and Search Domains areas, but at least in that case there is a white box to input text.
I can choose the "Configure IPv4 Using DHCP Manually" and that will let me input numbers, but I have no idea if I should even be playing around with this.
Also, perplexing me even more, is the fact that I can choose my Linksys internet connection through the Airport screen, and when I have selected it, I show full bars. But I can't actually connect.
Silly me, I attempted to call Comcast for help with the issue, but they say that as long as I can connect to the internet in any way (plugged in) then they do not care that I can't connect wirelessly.
I miss checking my email in bed...someone please help!!!
Thanks a million in advance for any and all help.

Are u talking about routers username , password? Well there is one routers username ,password (default is "admin") and the other is your cable ISP username , password (on the routers webpage). I am talking about the latter. If nothing works, try resetting your router ... You will have to configure it again (doesnt take much time if you know it).

My Satellite A25-S279 (WinXP) will not connect to the internet wirelessly since UVerse was installed

My Satellite A25-S279 (WinXP) will not connect to the internet wirelessly since UVerse was installed. (Rather, I should say
it 'connects', then immediately disconnects.) When I had regular DSL, there was no problem, but since UVerse installation,
I can connect ONLY with the ethernet cable.
Thinking it was my 'old' computer, I took it to the local computer place---they were able to connect instantly (wirelessly) AND maintain connection. Sooo...I've told this to ATT, & had 2 different techs out here, both of whom were very patient & tried EVERYTHING they could think of, & both of whom failed to fix the problem. They maintain that it is NOT the fault of the modem/router, but is some 'miscommunication' between my laptop & the modem/router.
Is that possible? Is there a setting I need to change on the laptop? If it worked BEFORE UVerse, and if it STILL works at the Computer store, and if it works WITH the cable, why won't it connect wirelessly?
Thank you SO much for any thoughts!

It is possible. While it's not common, sometimes you could have a working router and a working wireless card in a laptop, but they just don't communicate. It sounds like that might be the problem unfortunately.

Can access Apple TV via airplay, but can't get to internet or iMac from Apple TV

Can access Apple TV via airplay, but can't get to internet or iMac from Apple TV. Whenever I try to put my info in it says to try later. When I test network it says network time has not been set. It has worked previously.

Try the following steps, check whether things are working after each step where appropriate, before trying the next.
Check AirPlay is turned on on the Apple TV (turn it off and on if it already is)
Check that both devices are on the same network (Settings > Wifi, on the mobile device and Settings > General > Network, on the Apple TV).
Restart the Apple TV (Settings > General > Restart).
Restart the Apple TV by removing ALL the cables for 30 seconds.
Restart your router. (Also try removing it’s power cord for at least 30 seconds)
Restart your mobile device.
If you are still having problems, the following article(s) may help you.

I have a Mac Pro 4,1 quad core intel Xeon running mac OSX 10.6.8 and I have just moved studios and now need to use the Internet wirelessly but there's no airport facilities on this model can anyone tell me what model of airport card I would need for this

I have a Mac Pro 4,1 quad core intel Xeon running mac OSX 10.6.8 and I have just moved studios and now need to use the Internet wirelessly but there's no airport facilities on this model can anyone tell me what model of airport card I would need for this mac

Instead of getting a wireless card for the Mac Pro, you might want to consider getting an 802.11ac wireless bridge device that would enable you to connect more than one device to it by Ethernet cable and to eventually take advantage of the faster 802.11ac wireless standard.

Need help connecting to internet wirelessly

Please help. I just had Comcast high-speed Internet installed in my home yesterday. I opted for their free d-link modem and wireless router promotion. When I connect the modem directly to my g4 ibook, I have Internet access. However, I'm having trouble connecting the d-link router. (I swear I've read the directions, but I don't understand.) The Internet coaxial hooks to the modem. The modem hooks to the router. The tech at d-link told me to connect the router to my laptop to "configure it"--whatever that means. Apparently he did it for me through the Internet. But then when I unhook the router from the laptop to use the Internet wirelessly (that's the point, right?), I lose the Internet access. I consulted the Apple manual for help, but it seems to only give me directions for configuring my laptop for a wireless connection to an Apple Airport Extreme Base Station. I'm not using an Airport Extreme Base Station. I have a d-link router. (The tech at Apple said they're the same thing.) Do I need to tell my computer to recognize the d-link router? How do I do that? I am very frustrated at what is probably something very obvious to all you computer-literate people out there. Please speak slowly for me.

Thank you for responding, Duane. Since I am at work right now, and my laptop is at home, I went to the AppleStore site to look up the specifications of my laptop. It has a built-in 54 Mbps AirPort Extreme (Wi-fi 812.11g). That's what you mean by an AirPort card, right?
So it seems I'm ready? You say to make sure AirPort is enabled? I will check that as soon as I get home, but I do recall the AirPort icon at the top (a gray icon that resembles radio waves) and I even clicked on it yesterday--from what I could tell through my tears of frustration--but I think it said "no network is available". What do you mean when you say choose my "network name" from the AirPort menu? What is a "network name"? I must be doing something wrong.
Based on my obvious cluelessness, you would be surprised at the ways I incorporate the use of technology in my classroom. I can teach my students to use Apple programs in amazing ways, but I am ignorant when it comes to a lot of the vocabulary that's necessary to work my way through this wireless router matter. Please bear with me.

When our iPad is in use on the internet, my iMac internet connection goes off. I can't get the two devices to work at the same time with the AirPort Express. Is there a setting somewhere I may have missed?

When our iPad is in use on the internet, my iMac internet connection goes off. I can't get the two devices to work at the same time with the AirPort Express. Is there a setting somewhere I may have missed?

When two or more devices conflict it typically means that the DHCP service is either misconfigured or is not running at all. DHCP provides IP addresses to local network clients.
Is your AirPort Express base station the only router in your current network configuration? That is, is it connected directly to an Internet modem and not to another router upstream of it?

AirPort Express (2nd gen), share internet wireless and wired in the same time

If I use my AirPort Express (2nd gen) and I connect the modem in WAN port, and a switch in the LAN port (this swich connect a computer and a NAS wired), can I share the internet wireless and via LAN and the same time?, the wireless devices and the wired devices would be in the same network?.
Thanks.

Thanks!

I have a Linksys WRV200 wireless router and the wireless signal is not working properly so I cannot connect to the internet wirelessly. the wireless light has a fast green blinking light. how can I fix the router?

I have a Linksys WRV200 wireless router and the wireless signal is not working properly so I am unable to connect to the internet wirelessly. The wireless light is blinking green very quickly and I connect and disconnect from the network constantly. How do I get the router to work properly

Hello James,
The flashing WLAN light means activity (data getting transferred). Try disconnecting all your devices and check whether the light is still flashing or disconnect the router from internet and do the check.
Do you have your SSID as linksys or the default one? If your neighbor has the same SSID, then traffic could result from your neighbor's one. Try changing your SSID and password. Make your security WPA/WPA2.
Hope this helps,
Thanks

Connected to network but unable to connect to the internet wirelessly

I recently installed a new hard drive in my dell inspirion e1405 laptop and I can no longer connect to the internet wirelessly using the WRT54G v2. When I use ethernet it works. It says I am connected to the network. I punched in the WEP key and I am connected. I power cycled my cable modem, laptop and router several times. I followed these linksys suggestions:
Checking the IP Address of the PC
Checking the Wireless Settings on a Linksys Router
Disabling Computer's Firewall
Disabling Proxy Settings
Pinging the Router
Pinging the Internet
and it still isn't working. I downloaded the firmware and that did not work. I am using XP MCE 2005. I updated the driver for my dell wireless card several times and also deleted it from the device manager and rebooted. Still nothing.
Anyone have an idea?

Well, hope this might help
make sure you only get IP from the router's DHCP. yes, you must set Obtain IP Address for all network adapter on your notebook (wired and wireless). the basic is, all things will be fine if this IP issue is not around. coz, at behind, they do something more than give / got IP, such as creating routing path automatically. that which will be guaranteed the success of ethernet communication for wired and wireless.
i cannot guess your problem, but you might want to do this.
first, as above said, just Obtain IP Address, make it for both adapter on your notebook
second, wireless security, must talk in same way (SSID, Channel, b/a/g/n) and use same key (WEP or WPA, passphrase/secret key).
third, if anyhow you got connected but still can't go through internet, but, you can ping or access your router, for example, open your router web server to do some change of the configuration, means your packet is stuck on the router and cannot deliver further to internet and it is gateway issue. no else.
well, three shots shall go but you might need more bullets coz this is called troubleshoot
let's see how it will go.
wish you luck
