Lion 10.7.2 network connections stall

I am currently typing this while booted from the recovery drive. Lion network connections seem to stall on my macbook pro. Interestingly, connections made from command line programs and applications running in virtual machines are not affected. Additionally, some programs become unresponsive when launched while connected to the internet, but launch normally when internet access is disabled (such as xcode and addressbook), while others always become unresponsive on launch(including keychain, mail). I have also observed 1Mbps incoming spikes occuring randomly during these issues. I have tried creating a fresh user account to no avail (hence I'm in recovery mode). My current theories are that either the network framework on the system drive is errant, so any applications that use it have problems while the ones that directly use the POSIX API have no problems, or that iCloud is blocked on my university's network and the sync services behave badly when the system is online and it can't connect to Apple. I intend to test each theory when I get home, or perhaps when I can use another network besides my university's, but I need the ports iCloud's services use so I can systematically block them and check if that is the cause of the issue. I'm personally hoping it's the former issue, as it will be far less annoying to reinstall the OS than to downgrade to simply use my laptop at school.

For a couple of weeks, no matter what I did with iCloud, nothing worked, except occasinally checking email with Mail.app. Today, everything is working. I noticed that in the logs there was a timeout error immediately after this message: UserEventAgent: CaptiveNetworkSupport:wispr_detect_redirect_async:424 user-agent:"CaptiveNetworkSupport-173 wispr" url:"http://www.apple.com/library/test/success.html". It seems this is how apple determines whether to display the login window. As to why it was timing out, I'm not sure, but I noticed that my iPod Touch had no issues and was connecting over a different subnet. It may have just been a network configuration problem at my school, or an overloaded login server. I'll post again if I have problems later.

Losing network connection in Lion.

I have noticed that in the past couple of days my network connection seems to go down for no apparent reason. I have to reboot iMac to get network connecitivity. I have my iMac hard wired to Linksys router. My network is not down since my iphone can connect wirelessly as well as my Macbook. I was wondering if there was a way to troubleshoot the issue. Would there be a log of any kind that I could look at in order to see what might be the culprit? What steps should I be taking to troubleshoot issue?
Thanks and I look forward to your reply.

I am experiencing the same issue on my 27' iMac (2011). Connections to shares get dropped often. I can reconnect sometimes, but others I have to restart AirPort. This is a major issue that is affecting my productivity.
Lion is not the OS I would have come to expect from Apple...far too many bugs. And to add insult to injury, Apple is silent and no patches are forthcoming?!
I guess their organization are too tied up patent trolling Android phone manufacturers and Google to insure quality gets out the door.
(Disclosure: I own 6 apple devices & 0 Android.)

WRT54G - limited or no connectivity - stalls at "aquiring network address"

Ok, so I decided to move my modem and router to a different location in the house and unplugged and re-set everything. I went through the basic setup and finally got to the point where I can get internet when the pc is wired to the router. Wireless, the pc is picking up the network fine but when it gets to "aquiring network address" it just stalls and eventually I get the message that I have limited or no connectivity. When I righ click on the network connection icon and click "repair" connection it cannot verify network address. My xbox 360 is also picking up the network but fine but will not connect. Everything was working fine beforehand but I cannot for the life of me figure out what setting needs adjustment.
Any suggestions?
Thanks

FWIW, this is similar to a problem I just posted. I got around the problem by selecting properties on the connection, and changing the settings under 'Internet Protocol (TCP/IP) Properties' to use a specific IP address.
These settings worked for me:
IP 192.168.1.101
Subnet mask 255.255.255.0
Default Gateway 192.168.1.1
Preferred DNS server 192.168.1.1
Alternate DNS server 192.168.1.2
I haven't yet found a solution to allow me to go back to obtaining an IP address automatically. Did you?

Using Juniper Network Connect with Lion

Has anyone had an luck using Network Connect to connect to a Juniper VPN with Lion? When I try to connect to secure network using Safari, Network Connect does not install and launch.

What version of Juniper are you folks running? We are still on 6.x (I'll have to check on what X is, I think its 5)
I enabled the java "enable applet plug-in and web sstart applications" and it still gets stuck on our host checker screen.   I set the developer Safari 5.0.6 and it actually gets past host checker, but does not present an option for network connect.
This tells me that host checker is running but no longer seeing what it needs to see (?) for the network connect option to be presented.   I was told by Juniper that an update needs to happen but it won't be availble until September.
Can someone verify they can actually get a network connect session working using Lion and safari 5.1 and how they got it to work, and what version of Juniper they are on?
If we need to get to 7.x we can do it on a test box but moving production there will take a good long time.   We *just* enabled the Mac VPN service at our company, and now those upgrading to Lion are finding themselves once again without VPN capabilities.    This is a real problem as we don't control weather they upgrade or not, and everyone wants to get to the latest OS.
Juniper is on its last legs at our company. This is probably the straw... they should have had this tested by now.

Upgraded imac to lion now can't keep connection to wireless network, iPhone and iPad are fine?????

Have upgraded my imac to lion and now it can't hold onto my wireless network connection, also having intermittant problems with mail incoming, and not able to send mail out. Wireless network, and mail working fine with my ipad and iphone. Any ideas out there??

I actually had that problem when I was downloading Lion it would connect but then if I tried to go on safari it said no internet connection and an exclamation point would be in the wifi bar. If you click on you wifi bar click on the option that says no error no internet or something like that. I deleted my network and then reestablished it as like it was the first time has been fine since even after the upgrade. I was in panic mode when it happend to because all my other stuff worked and i just got my new imac last week

Windows 7 Pro not finding network connections after boot camp installation. Is there something special we have to do to get the network (wired and wireless) set up?

If you haven't yet installed the Windows Support Software, that's probably why, so install it now.

'"Connection Failed" : The server "rrnas01" may not exist or it is unavailable at this time. Check the server name or IP address, check your network connection, and then try again' message

'"Connection Failed" : The server "rrnas01" may not exist or it is unavailable at this time. Check the server name or IP address, check your network connection, and then try again' message keeps displaying whenever I try to open any Adobe CS5 applications (except for Adobe Acrobat Pro). It displays until I click "OK" about 15-20 times or so and then will finally let my program open.
I have tried deleting files within my Library/Preferences folder and turning off/deleting login items within my system preferences as other forums suggested but nothing happened. Spending 3.5 hours on the phone with Adobe and completely uninstalling and then reinstalling the entire CS5 Master Collection didn't work either.
Also, it may be helpful to know that my programs worked fine for about three weeks then when we got internet and changed the password (the join, not the adminstrative password) with the wireless network "ScubaSteve" (which I've used with no problems at my old apartment) it started acting up. I have never seen "rrnas01" before so I don't know at all where it came from. I also installed the free 30 day trial of Suitcase Fusion 3 recently, but thinking that could also be the cause I have uninstalled it, and still no help.
Please help me! And please keep in mind I don't know all the computer lingo that a lot of the people in these forums seem to know. Thanks in advance for ny help you can give me.

It may not be possible .. there is a major bug between Mountain Lion and the TC where the TC disk goes off the radar of the computer.
Lion is also affected but not as badly.
7.6.4 seems worse than earlier firmware.. so back to 7.6.1 or 7.5.2 if that is possible.
Obviously that is not a solution for a later Gen5 TC.
Reset to factory after the firmware downgrade. .use all network names that are short, no spaces and pure alphanumeric.
If the TC is the main router set the dhcp to a very short lease time.. eg 30min.. and see how it goes, or try a longer lease like 99days.
I prefer the very short lease but response has been mixed.
Use ethernet not wireless.. ethernet is always more reliable and stable than wireless.
And last .. a nightly electric timer that powers off every night at midnight for 1min.. would not be the first device we have suggested a fix that amounts to beat the unit to the punch by forcing it to reboot since it is unstable.

How do I stop InDesign from trying to create a network connection?

I have a huge problem, either with InDesign or Apple I am not sure.
Basically when I bring my computer home from work every time I open InDesing it tries to connect to a server and I get this error message: the server XXX.local may not exist or is unavailable at this time. Check the server name or IP address, check your network connection, and then try again.
Why is InDesign trying connect to a server? Photoshop and Illustrator work perfectly well and function as a normal program. Indesign has no reason to do this as it should need to work through a server.
I get this error message and once I have dismissed it, it comes back after a few seconds and then stalls my computer again.
I really hope that someone can give me some idea of what is happening because the support in my country have not been at all helpful. I am asking this same question on the Adobe forums.

I get no messages from ID for InDesign or anything else and I am running CS5. I can't install Little Snitch because it is a work computer and my IT won't let me me do it. They have mentioned reinstalling it but our IT department haven't said anything more than that and frankly I don't think they would register as an issue that needs fixing as such.
The drive it is looking for is the timecapsule.local which I have turned off and on again and nothing has helped.

Error msgs in app store; network connection could not be made

Anyone else having trouble downloading apps directly from the appstore on your iPhone or iPad?
50% of the apps do not want to download. The msg I will get is that there was a problem and it will be available for download next time I connect to iTunes. And I already paid for it
Connecting to iTunes on my iMac tonight there were updates available for apps, I clicked to download them and again about 50% of the apps will not download. I now get the error msg that that app blah blah blah could not be downloaded because a network connection could not be made. Even iBooks won't download. Others download fine.
The apps I purschased on my iPad or iPhone and that did not download are nowhere to be seen.
Any insight?
cheers,
Christine

Just thought I would add that I did every test the help files suggest, no firewall etc.
Strange thing is that after the majority downloaded I had about 55 apps left that could not be updated because of the network connection that could not be made, I downloaded them manually instead of clicking 'yes please do download them all'.
I still came across a few that gave me the msg that an connection could not be made but when I skipped them and came back later to try again it did download. Took some time but I now have them all up to date.
Now see if I can sync the iPhone and iPad.
I run the latest iTunes 10.4.1 (10) and 10.6.8, have not updated to Lion yet.
cheers,
Christine

Mac Mini *half* loses all network connections

Cheers folks, new one on me. I have a Mac Mini 2.26Ghz Core 2 Duo. It's running a fully-updated 10.6.8. It's connected via ethernet to an Airport Extreme which is extending an 802.11N network from another Airport Extreme elsewhere which is connected to the router. The network is set with IPv6 *off* and is configured to run over Ethernet normally (this is because a wired-only NAS is connected to the same Airport Extreme as the Mini).
Here's the symptom, and it's an odd one for me: Every couple of days, the entirety of the Mac OS X layer (not the BSD layer) will lose network connectivity. More specifically:
No web browser will work ('Not connected to the Internet').
Home Sharing, served on this Mini, will cease to be visible from elsewhere in the house (AppleTVs lose it).
No internal services can be reached by name, either DNS or BonJour.
The App Store says 'can't connect.'
iTunes will say it can't connect to the ITMS.
This is true on Ethernet *or* on Airport (the Mini usually runs on ethernet alone with AirPort off; bringing up Airport once this has occurred doesn't seem to help anything).
Running the Airport Utility, it sees *no devices* (there are 4 on this network)
BUT!
If I go into the Terminal, I can not only get clear network traffic anywhere I want at the TCP layer, DNS seems to work as well. So the following is true also:
'ping cisco.com' (or any valid DNS name) works fine - resolves DNS, pings.
'traceroute cisco.com' works fine - resolves DNS, traceroutes out across the internet, no problems.
'ping <IP address of NAS>' - works fine.
'dig <name>' - works fine.
pinging the gateway (the router airport) works fine.
Also:
Other Macs in the house (on wired OR wireless, connected to any of the AirPorts including the same one as the Mini) work fine.
Other Macs can see the NAS connected to that same AirPort fine.
iOS devices in the house connected to any AirPort work fine.
netstat -r shows what look to be proper routes - i.e. the default gateway is the router address (10.0.1.1) and the route to 10.0.1.1 is shown to be the MAC address of the router's Ethernet interface (anyway, as I mentioned above, network stuff from the shell works fine<!?!??!
Steps tried:
Turning off ipv6 - nope.
Applying all firmware/software updates (OS X 10.6.8) - nope.
Tried manually setting DNS to Google public DNS servers - nope. Those work fine, and are still set when the network drops out, and then don't work, nor does setting new DNS servers in the Network prefpane.
Logging out/back in - nope.
Restarting the computer: YES. This works, all three times this has happened (all this week). Serious PITA.
I tried going through the system log, but I don't see anything notable that changes or is logged when the network connection drops.
Every time the connection has stopped working, the computer *has* slept at some point since it was last known working, but if I sleep the computer manually, everything seems fine.
.....waaaaaaaah! Help, this one is making me crazy. :-) Thanks. I'm terminal-savvy, and fairly OS X savvy.

I still have this issue. About every one hour - two days the DNS layer will stop working and only a restart will fix it.
Killing mDNSResponder only resolves the issue sometimes and even then for a few seconds.
I have now found and created the following bash script, to see if this will be a more reliable non-restart fix that killing mDNSResponder in the terminal:
#!/bin/bash
#Script to unload and reload mDNS as it is a bit crappy
sudo launchctl unload /System/Library/LaunchDaemons/com.apple.mDNSResponder.plist
echo "mDNS unloaded"
sleep 5
sudo launchctl load /System/Library/LaunchDaemons/com.apple.mDNSResponder.plist
echo "mDNS loaded"
sleep 5
echo "Hopefully you can get on with browsing again"
I saved the above as mdns_reload.command, and then in Terminal ran "chmod u+x mdns_reload.command". This makes the script executable.
The next time the problem occurs I am going to test how good this script is as a resolution.
The second time the problem occurs I am going to try the following, from a different thread from 2011:
I don't know if anyone will be helped by this, but the Macbook problems connecting to the internet are directly related to DNS issues. I discovered this after an upgrade to the OS X Lion preview.
The symptoms are as follows: a macbook (pro, mini, etc) can get an IP address from a DHCP server on any given network, but can not connect to the internet, even though other computers on the same network have no issues. If this sounds familiar, read on.
The problem is not related to 3rd party products, routers, Airport settings, locations or public vs private DNS servers, and you don't need to reset SMC or PRAM.
You will need to use terminal and you DO NOT want to use disk utility to repair permissions.
The most direct way to fix this is to copy the com.apple.mDNSResponder.plist and com.apple.mDNSResponderHelper.plist files from an internet connected Mac into your /System/Library/LaunchDaemons directory.
(You should know that it probably doesn't matter what version of OS X you have or the other Mac has, you just need the files.)
Next you will need to change ownership of the files just copied (ex: chown root:wheel /System/Library/LaunchDaemons/com.apple.mDNSResponder.plist and chown root:wheel /System/Library/LaunchDaemons/com.apple.mDNSResponderHelper.plist)
Then, you will need to set correct permissions (ex: chmod -R 755 /System/Library/LaunchDaemons/com.apple.mDNSResponder.plist and chmod -R 755 /System/Library/LaunchDaemons/com.apple.mDNSResponder.plist)
The last thing you'll want to do is to verify that the ownership of the files copied is set to system (and maybe wheel) using "Get Info." (Conversely, you can use ls -l /System/Library/LaunchDaemons/com.apple.mDNSResponder.plist to verify owner and permissions.)
You should not have to restart to connect immediately to the internet.

When I upgraded my iMac to Lion I can no longer connect the iPad 2 to WiFi. It gives me a message unable to search for WiFi. Before the upgrade to Lion it worked fine. What gives?

When I upgraded my iMac to Lion I can no longer connect the iPad 2 to WiFi. It gives me a message unable to search for WiFi. Before the upgrade to Lion it worked fine. What gives?

Could there be a setting I need to adjust in the iPad2? When I try to turn on WiFi and enter the name of the WiFi that I have established, including the security type and the password, I get the message "Could not scan for wireless networks." Is there a setting in iCloud or other location that needs to be changed?
