Network problem (connections)

hi folks.
updated from Tiger.. have my connection with a classic network cable..
when i log in i got
3 alert saying
*"impossible to connect to the network device"* (translated from the italian "impossibile connettersi al dispositivo di comunicazione")
this happens once, then twice (in the meanwhile my connection works) then it happens for the third time, my connection stops, and after the message disappear it starts working again.
in the network preferences the connections order is done rightly.
Ethernet is the first connection avalaible.
any hint?

Hi,
I´ve got the same problem. Sometime I start or restart the computer, I get the same3 alert messages ( in German ) as you. If I disconnect the cable from the computer and connect it again, the network is back again. What iMac do you have? A new one ( alu )? Is it a hardware problem?

Wi-fi network problem connecting & disconnecting

my MacBook Pro wi-fi network is giving me problem after I changed to Fiber Network.
It keeps connecting and disconnecting the Wifi network. I have no problem using Ethernet.
Anyone know what happen?

yes, 8.8.8.8
What servers do you have in your network? and what DNS are they using?
i changed to DNS of mine ISP's，210.22.70.3, still can not go everywhere but google's service
and if i set the DNS of ipad to a invalid server, i can not open google's page too

Problems connecting multiple macs to an Airport Extreme network.

I think this problem is similar to a previous post, but is individual in some ways.
I have 2 Airport Extreme basestations covering a large flat connected by Ethernet extending a single network. I did try to extend the network wirelessly, but this was plagued with problems where the network would work for 10 mins, then drop out as I think the basestations are slightly too far apart.
Connected to the network are a number of machines:
Wirelessly we have 3x iPhones, 1x G4 Cube, 1x iMac (current model), 2x MacBook Pro (previous model) & 1x PC.
Wired via a hub is an Apple TV, PS3, Nintendo Wii, Denon Home Cinema Amp, PS2
For aprox 6 months I have had major problems connecting all the wireless machines at the same time. I have played around with the security as per previous posts with varying degrees of success.
I seem to have the most problems with the iMac. The iMac will not join the network when there is any form of wireless security. Every time I try to set up a password it hangs when trying to join and I finally get the "There was a error joining xxxx network".
After more playing around I managed to get all the machines working by having no security on the network and locking the network down by MAC addresses.
Since last Thursday I now have a new problem. The iMac joins and stays on the network perfectly, but the second my second MacBook Pro is switched on and joins the network, the internet connection on the iMac drops out. In addition, as we use the iMac as a media server, all other machines connected to the iMac for either file sharing or iTunes sharing then get the error "the remote machine is failing to respond. Please check firewall settings if there are any". What is strange is that the iMac remains on the network, full signal, independent IP address and the second the MacBook Pro is switched off, works perfectly again.
I have tried wiping both the iMac & the MacBook Pro and re-installing their operating systems, but this only solves the problem for aprox 24 hours then all of a sudden the issue re-appears.
Can anyone out there help?

Let's double-check the AirPort Express Base Station's (AX) settings ...
Perform a "factory default" reset of the AX
o (ref: http://docs.info.apple.com/article.html?artnum=108044)
Either connect to the AX's wireless network or connect directly, using an Ethernet cable, to the Ethernet port of the AX, and then using the AirPort Utility in "Manual Setup" mode, check the following settings:
AirPort > Base Station
o Base Station Name: <rename or leave default>
o Base Station Password: <enter desired password>
o Verify Password: <re-enter desired password>
o Remember this password in my keychain: (optional)
o Set time automatically: (unchecked)
AirPort > Wireless
o Wireless Mode: Join a wireless network
o Network Name: <existing AEBSn's wireless network>
o Wireless Security: <select the encryption type of the existing wireless network>
o Wireless Password: <enter the existing wireless network password>
o Verify Password: <re-enter the existing wireless network password>
Music
o Enable AirTunes (checked)
o iTunes Speaker Name: <enter desired speaker name>
o iTunes Speaker Password: (optional)
o Verify Password: (optional)
o Click Update to write the new settings to the AX
In iTunes:
iTunes > Preferences... > Advanced > General
o Look for remote speakers connected with AirTunes (checked)

Got a new MacBook pro but for some reason I can't connect to my schools wireless. It doesn't have a problem connecting to any other wifi. My schools network is unsecured all you do is login with your username and password but the window never loads

I jus got a MacBook pro and Im having trouble connecting to my schools network. It is not secured and only requires to login with school id. A Window pops up to sign in but it never loads anyone know why I'm having this problem? Doesn't have a problem connecting to any other wifi

"This is a flaw in OS X Lion. It does not want to connect to open WiFi that has a login page that open in a browser."
Nonsense, no problems logging in at sites that you mention. I use OpenDNS servers. For the OP try:
System Preferences>Network>Advanced>DNS. In the left side column click on the + sign and insert the following:
208.67.222.222
208.67.220.220
Then click OK, then click Apply.

I'm having a problem connecting my BlueRay DVD player and other non-Mac devices to my wireless network. Is there a limit on the number of devices I can connect to my AirPort? I never have a problem connecting an Apple device (AirBook, iPad, etc).

I'm having a problem connecting my BlueRay DVD player and other non-Mac devices to my AirPort Express network. Is there a limit on the number of devices I can connect to the wireless network? I never have a problem connecting a new Apple product (AirBook, iPad) and even a basic laptop. Thanks for your help.

The AirPort Express Base Station (AX) can support up to ten (10) simultaneously connected Wi-Fi clients.

My iPad2 no longer connects to my home wifi network but there is no problem connecting to other saved wifi networks. Currently using iOS8.0.2. with storage capacity of 12.2Gb but only 147Mb free. Disconnecting the router and rebooting the iPad worked

My iPad2 no longer connects to my home wifi network but there is no problem connecting to other saved wifi networks. Currently using iOS8.0.2. with storage capacity of 12.2Gb but only 147Mb free. Disconnecting the router and rebooting the iPad worked briefly as a temporary fix but not anymore

You could try this
Temporarily disable security on your home network
See if the iPad connects
If it does then reset the security - with the same or different password

TS1398 I have been having network problems on my Ipad and I reset all network settings as advised in the article about problems connecting to networks. Now my Ipad will not allow me to sign onto any network....it will not accept the passwords for any net

My ipad has been a little glitchy for the last couple of weeks....not able to load pages because of DNS lookup failure and really slow loading...some of which has to do with the DSL service I have, but I followed the directions on one of the Apple wi-fi issues pages to reset network all connections..which I did, and now the Ipad cannot connect to WiFi because it will not accept (or cannot resolve..or??) password. I am sure I am typing the password correctly and have tried it on several routers..and it cannot cannect to any router properly even with the correct password. My laptop is connected just fine and it accepts the password and I have confirmed the password with the ISP and tried other routers.
So the question is what should I do if I am entering the right password and the Ipad can't sign itself on to the Wifi network?

Some things to try first:
1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
4. Go into your router security settings and change from WEP to WPA with AES.
5. Renew IP Address: (especially if you are droping internet connection)
    •    Launch Settings app
    •    Tap on Wi-Fi
    •    Tap on the blue arrow of the Wi-Fi network that you connect to from the list
    •    In the window that opens, tap on the Renew Lease button

Hyper-V 2012 R2. RemoteFx. "The remote session was disconnected because there were network problems during the licensing protocol. Please try connecting to the remote computer again."

After a Installation from Windows 8.1/windows 7 everything works fine. For example Install updates and Software. If I connect the first time a remotefx card i can use RDP as well. But if i restart the host I get the mentioned error. What can I do. These
Hosts are not in a domain configuration. I tried it too but there was no difference. I didn't discovered any errors in the eventlog, too. Only an actviex error. But same errors occurs with a succsefull rdp session.
Also strange is if i start the vm without a remotefx card it works fine again. Only session with a Remotefx card aren't possible anymore.
Is there a bug or something. I tried it many times with the same error.
Maybe someone can help me.
kind regards
Tobi

Hi Tobi,
Thank you for posting in Windows Server Forum.
For a workaround, please try to perform the two steps.
1. Do NOT enable RDP 8 on the Windows 7 SP1 VM. You should install RDP 8 and update the ICs though.
2. Change the connection setting on the client from "Automatically detect" to "LAN"
Please check again below thread for information.
a. "The remote session was disconnected
because there were network problems during the licensing protocol" after enabling RemoteFX Windows 8 VM
(Please recheck answer by “dgeddes”)
b. "The remote session
was disconnected because there were network problems during the licensing protocol" After Installing RemoteFX
Hope it helps!
Thanks,
Dharmesh

Problem connecting to a wireless network

I am using 'Aztech' wifi router/ADSL modem for wireless network at my home. I had been connecting fine with the internet using it until yesterday, when, after a software update, I have been unable to connect to the network (I can access it with my wife's laptop, an acer running windows XP). I tried reconfiguring the connection, reconfiguring the settings of the wifi router and even reinstalling the software, but without any positive results.
The current situation is: I can see the network in the list but when I try to connect using the correct password, I keep getting the message "There was an error joining the Airport network '(Network Name)'".
(I have no problem connecting via the cable)
Help me out please...
Mac Book 2.0 GHz Mac OS X (10.4.8)

I had the same problem with my Macbook after the update. It will no longer connect to my router using WPA-PSK authentication. It did work for me after changing my security settings back to using WEP authentication.
I have not been able to figure out the reason for this but this may help get your Macbook back on the internet for now.

Problem connecting ATV to my network

I am just setting up ATV and being told "There was a problem connecting to the network (check your settings and try again (-1) " I am trying to connect to my airport extreme...anyone know how to solve this?

Still having a problem? Are you sure that the password is correct. Seems like I remember (-1) meaning a bad password...let me know.

I had no problem connecting to my network and now all of a sudden I can't connect. Instead of prompting me for a password it comes back and says unable to join the network ("name") and then the option is Dismiss. Anyone else have that problem?

Instead of prompting me for a password it comes back and says unable to join the network ("name") and then the option is Dismiss. Anyone else have that problem? I've gone thru all my settings and can't seem to find a way to log into my network. Don't get the option to put in my password. It just give me the name of my network and option of dismiss instead of password.

LaCie MiniHD connect network problem

I have a LaCie MiniHD connect in my local network. Did everything LaCie told me to do so I could write to the USB attached LaCie drive.
Formatted the drive in OS X EXtended but not journalized.
Tried to connect via smb://MiniHD.smb.tcp.local and the network told me to enter my ID and Password, I don't know why.
So I brought back the disk drive to my mac and changed the whole drive permission to read and write for everyone.
Brought back the drive to my TV and now I could transfer anything from my mac to the drive.
I was glad of that, but having shut down the drive and the MiniHD connect, when I opened it again to transfer something from my mac to the drive, I still got the same problem again with the same message.
"One or more elements cannot be copied to "LaCie_750" because you don't have the permission to read. Do you want to copy the elements you are authorized to read."
I suspect the software on the Lacie MiniHD connect to block OS X when it initialises the drive on startup.
In particular I see a folder named _HF2VN~W appearing in the root level of the drive.
Can any one help me with thi samba network problem on Mac OX 10.6.5?

I have since had a reply from LaCie to say that this issue has been identified and is being worked on - however I'm afraid that I don't have any timeline for when this will be fixed.
