MacBook Pro :: "Network Connection The Communication Device Selected For Your Connection Does Not Exist?

Mar 16, 2012

The internal modem in my PowerBook Pro (mid 2010) shows up as "not connected" in the Network pane of system preferences, but I can't figure out how to get it to connect. When I enter my phone number and click the connect button, I get an error message: "Network Connection The communication device selected for your connection does not exist. Verify your settings and try reconnecting." Say what? It says it exists in the System Preferences, shows it in the list on the left. How can it not exist?

OS X V10.7 Lion :: Force System To Use Second Connection Of Network Connection List For Internet Access?

Jul 5, 2012

I have a MacPro Early 2009, 2 ethernet ports.Ethernet 1 is connected to the LAN and Ethernet 2 is connected directly to a SSL Matrix console (an audio mixer), whom driver needs the used ethernet port to be first of the list in the Network connections list in System Preferences.So when I browse internet I can't use the Matrix's software, and vice versa.I had to create 2 different network positions to browse internet and to work with SSL Matrix, one with Eth 1 first place, another one with Eth 2 first place, and I always have to swap positions.Is there a way to force OSX to use by default the 2nd connection of the list for internet access?

MacBook :: Unable To Share Network Connection / Connected Via Ad-hoc Network?

Dec 31, 2010

I have Alltel Mobile Broadband. Up until the other day, it's been working fine. I'd set up a network on my macbook after connecting to the Alltel network, then I'd enable internet sharing. Then my iPod Touch, iPad, etc would all be able to go online.

The past couple days, however, the connection just won't share.Anyone have any idea what could be doing this and how to fix it?

MacBook Pro :: Airport On Brand New 13" - Wireless Connection Losing It's Connection

Jan 26, 2010

I recently purchased (as in days ago) a refurbished 13" Macbook Pro. I just noticed today that my wireless connection on my Macbook Pro has been losing it's connection about every other 2-3 minutes. I was on iChat with a buddy this morning, and I must have been disconnected and then reconnected about 8 times in 20 minutes. I first thought it must have been a problem with iChat. That said, I have sat here looking at my screen for the past ten minutes, and I have seen the Airport wireless indicator disconnect and then reconnect again at least three times in the past ten minutes.

I have AT&T U-Verse Service, and I am forced to use their provided 2WIRE router. That said, I have had no problems with any other device that uses the wireless connection, from my iPhone to my PS3. I work from home and have my HP laptop literally sitting right next to my Macbook, and it has not disconnected once from the same wireless connection, whereas my Macbook has literally disconnected at least 20 times.

MacBook Pro :: Network Fails After VPN Connection

Apr 26, 2012

I use VPN to connect to my work. Sometimes I leave it on when I stop for the night. When I go into work, I usually can login to my laptop either via VNC or ssh even when the tunnel is enabled. But, now my laptop becomes totally unresponsive and unable to receive or initiate connections.After I came home, I tried the basics. DNS completely failed. Connections to my local network seemed to work OK (192.168.1.X). However, anything else was not possible. I tried running nslookup to see what was happening. [code] I tried using ifconfig to take the network interface down and then back up. I tried disabling and re-enabling wifi. About the only thing I've been able to do is reboot the machine.

OS X :: New Folder From Selected Items In Finder - Exist?

Dec 1, 2008

I frequently want to grab a ton of junk on say my desktop and sort them into folders. Process is "make new folder, select all the items I want to go in it, drag them to it, name folder, move folder to where I want". What I want it to be able to do is select all those items and have a contextual menu command "Make New folder from selected". Ideally, popping up an Open/Save dialog letting me choose where to put the new folder and allowing me to name it. On closing dialog, I have my new renamed folder with all my selected stuff in it, wherever I want on my HD with no extra dragging and clicking. Does this sound worthwhile to anyone else? Am I missing some way that this can be done? Seemed like an obvious thing to me, was kind of puzzled to discover (AFAIK) no way to do it.

MacBook :: Wireless Network Connection Timeout?

Apr 19, 2009

I have a macbook 2.4.

I used to connect wirelessly through a router. I can't connect anymore with my macbook, I have a message "connection timeout" when I choose appropriate network and type the code (I tried both WPA and WEP). The thing is I can connect without any issue onto the same network using a pc.

I have also a partition with Windows vista on my macbook but still I can't go online.

MacBook :: Unstable Network Connection - Won't Load Any Site

Nov 5, 2010

What happens is that i attend a school, where we are 700 people using the same internet. Actually it's divided into 4 sections, so there are probably 250 in my group. This network is protected by a WPA2 password, and has additional login forms, which gives the school the ability to check all in- and outgoing transfer. However, I have lately been getting some problems connecting. What happens is that I connect, and it works for about 2 minutes. Then, it just won't load any sites and just keeps trying to load until it finally admits that it can't retrieve the server. It's my third year. and I have never experienced this before, so I thought: Well, gotta be the school's internet, but i haven't heard of any other ones having this problem. This makes me worried that my macbook's airport extreme card is broken.

I was wondering if anyone had experienced a similar problem, or maybe could give a hint towards a solution? I am running a 13 inch macbook unibody (the silver one), with the newest system and all upgrades installed. Problem is: The airport extreme card is located in the display. I don't get why, but it makes me not want to change it myself, should it be destroyed.

MacBook Pro :: Connection Failed Trying To Find Network Drive

Jan 22, 2009

My company uses a network drive attached to our router. I can connect to the drive fine, but only after a fresh reboot. If I turn on off the MBP or hibernate it, when it boots back up it tells me it can't find the network drive. Trying to reconnect to the network or turning airport on and off doesn't work. I have a mac mini that i never shut off that never loses connection, only the laptops.

MacBook :: Cannot Find IP Address For Wireless Network Connection

Jul 6, 2010

I have just bought a macbook, my internet connection at home is wireless however it requires the IP address of each computer using the wireless network to be entered into my wireless account, just an extra security measure. My new macbook has never been connected to the internet as I can not find the IP address I have tried applications/utlities/network utility and there is just a blank space where it says IP address. I have also tried System prefences/network and there is no IP address there either.

MacBook Pro :: VPN Connection Through Network Connect, NC Does Not Load Anymore

Mar 8, 2012

I recently purchased a Mac 10.7.3. I was never a Mac user, so I am kind of lost.I was connecting through VPN Network Connect at work, but it recently stopped working. I read a few support stuff saying that there is a bug with the new JAVA update, Juniper Networks and Apple updates. I am not sure if that's what happen. This is the message that I get when I try to load Network Connect : System extension cannot be used The system extension “/usr/local/juniper/nc/7.1.0/nctun_tiger.kext” was installed improperly and cannot be used. Please try reinstalling it, or contact the product’s vendor for an update. After I hit cancel and try again, I no longer get the message, but it just loads endlessly.  I tried deleting NC and reinstalling it, but it don't work.  I tried running the tunnel through Google Chrome rather than Safari. I tried Java updates. Nothing works.IT at work is not Mac friendly and the company that manages all the VPN access is also not that savy and says it's my problem. Given that I am not too familiar with Mac yet, I can't get out of it on my own.

MacBook :: Turned On - Computers Lost WiFi Network Connection

Apr 12, 2010

For the past few months I've been using my mid-2007 MacBook (running Snow Leopard) with a Samsung external TV/monitor (with the MacBook's lid closed). I had no problems whatsoever in terms of internet connection to my D-Link DIR-655 router. Yesterday for the first time since creating this setup, I took the MacBook with me somewhere. When I returned the MacBook to my network (closed lid, plugged my monitor back in), I started having WiFi trouble. The WiFi was initially running very slowly and then not at all. The WiFi icon on the menu bar was showing regular strength, however.

The complicating factor here is that when my MacBook is on, all other computers on the network show getting WiFi signals but the connection isn't working for them either. When I turned off my MacBook and powered down/up the modem and router, other computers could connect successfully. (But when I turned my MacBook on, the computers lost connectivity to the internet. I've already played with the router's channels without success. I also made sure there weren't any unnecessary items in my Mac's DNS listing.

MacBook Pro :: Repeated WiFi Timeouts With Home Network Connection

Apr 18, 2012

All day, I am able to use the internet (via WiFi connection) at the library. But when I get home, I can't connect to my home WiFi connection. This was never an issue before. I have done all of the obvious things (resetting my router, clearing saved connections from my computer and joining a 'new' network, check and installed all updates, etc etc), but nothing seems to work. All the other devices in our house are connected to the WiFi just fine.

I run the diagnostic and I'm only green on WiFi and WiFi settings, with network settings and ISP fluctuating between yellow and red, and internet and server is always red. I have tried DHCP Lease renewel (which usually does the trick when I am getting an invalid IP address (169.xxx.x.x) until I get a valid one (192.xxx.x.x). But now sometimes I'm not even getting an IP at all!All I wanna do is unwind, check/reply to emails just surf the web to decompress after my long days.

OS X :: Ad Hoc Network Wiped Out Regular Network Connection?

Jan 7, 2011

I've searched and don't see anybody else with this problem. I tried to set up an ad hoc network on my MBP so I could use TouchAble with my new iPad. But now I can't get my MBP (or iPad) to see my home wifi network.

(TouchAble is a music performance app on the iPad that controls Ableton Live on the MBP. It works on an ad hoc network so the combo will work on gigs without depending on local wifi.)

I set up a new network ok, with a password. The iPad saw it, but before I tested it further I wanted to make sure I could reinstate my regular network. So I tried switching back to the regular wifi. No dice! The MBP sees the network, but I can't log in. It acts like the password is wrong. Same on the iPad.

Yes, the network works. I didn't make changes to the settings in my router, and my iPhone still sees it with the same password.

I tried a tip I found online and deleted the network preferences file (com.apple.smb.server.plist) and rebooting. No dice. (The system didn't write a new one, as I had expected; I had to reinstate it from the Trash). I rebooted a few times, both MBP and iPad. Nope.

What's going on here? 1) How can I get my MBP to see my network, so I can switch back and forth from the ad hoc to the local network. 2) Ditto for the iPad.

MBP is new. All systems and versions are up to date. No other funny stuff with the network--it's been stable for two years. Everything is stand-alone; this is in my home office. I'm the admin. (But I'm not a techie, so if you start talking about IP addresses and subnet masks, please be clear what I should try.)

Hardware :: Switch Time Capsule To Wired Connection / Using Wifi Connection On Smartphone?

Feb 10, 2009

I have a Time Capsule wirelessly connected to my iMac. Since I've encountered some problems with backups because of intermittent wifi connection failures, I want to switch to a wired connection with an ethernet cable. I know I could fiddle with the wifi channels etc. but since the TC is just sitting next to my iMac anyway, I could profit from the higher bandwidth of a wired connection as well.Two questions:

1. What exactly do I have to do to make the switch? Are there any new settings I have to apply? Create a new network?

2. Will I still be able to use the wifi connection to get on the internet using my smartphone?

Software :: Internet Connection Hangs Disconnecting Using Mobile Connection (GPRS, EDGE, UMTS)

Aug 21, 2006

I'm on holiday using my mobile phone (Nokia N80) to connect to the Internet over GPRS / EDGE / UMTS. Everything works like a charm, but often the Internet Connect applet drops the connection and just hangs disconnecting.

I'm running OS X 10.4.7 on a 17" Macbook pro, but I have the same result on a iBook G4, same OS X version, and even trying with a different mobile phone (Nokia 6600) and different network service provider.

Software :: Internet Connect Cannot Open Communication Device

I get a persistent and annoying pop-up that says "internet connect cannot open your communication device"--even when I am already connecting fine (through airport express). And from what I understand, Leopard doesn't even HAVE internet connect. I'm really stymied. Someone else suggested it was an Entourage schedule problem, but that advice didn't work either.

Hardware :: UPS Connection With Time Capsule - Can Operate With UPS Via USB Connection

Jan 4, 2010

I was wondering if Time Capsule can operate with UPS via USB connection (like QNAP or Synology or FreeNAS) ?
Is there some option for it in firmware ?

I have the USB cable to connect the UPS to computer / other, and UPS can work this way ( Smart APC 650 ).

If not, i was wondering if Apple could add this function. I have AP client, 3 hard disks and 3com gigabit switch connected to TC. It would be nice if TC could check the power status of UPS, and work with it.
