Loss of network connection with update 7.6.4

Since updating my airport to 7.6.4, I keep losing my network (Comcast) connection. Restarting airport gets me back online. Anyone else experiencing this problems since the update? (OS 10.6., MacBook Pro)

Same issues here. Ping loss every 4th ping.
found this thread > https://discussions.apple.com/thread/3482505?start=15&tstart=0
Suggested is to downgrade which I did .... result is no ping loss anymore.
I downgraded from 7.6.4 to.7.6.3
I hope this also works for you!

Sharing a network connection with an Ipad2

I have a windows desktop connected to a network. I'd like to share the network connection with my Ipad while it is connected via the USB cable to the desktop. Is this possible? How?
Thanks,
Shaun

Well duh - no. I misread the question. I share the Internet connection from my iMac which is connected to the Internet via Ethernet cable to the modem.
The iPad shares my iMac's Internet connection through internet sharing. The iPad is not connected to my Mac with the USB cable. Brain clot! But is it not possible to share the connection via Internet sharing in the Windows world?
Sorry to the OP!

Loss of network connectivity at random times to guests and now hosts Server 2012 R2 Hyper-v on Dell R620...Guests virtual disks reside on a NAS.

We have set up 2 Hyper-v environments (Server 2012 R2 fully updated) on Dell R620's. The guest machines are configured do that they reside on a NAS (also a Dell R620 with server 2012). We are having an issue on both the environments where the guests will
lose network connectivity. The servers ran well for about 4 weeks and recently the guests started having issues and we have even had to reboot the host due to network connectivity problems.
We have 4 virtual switches set up. 1 connected to its own NIC. 1 for management and the 3 others for guests.
The 3 for guests are not configured to allow host OS sharing.
We do not have IP addresses on the NICS for the guests. Only on the management port. (all 1 GB NICS)
We have updated the firmware and drivers for the standard Broadcom Netxtreme cards.
We do not have Jumbo frames enabled because of some issues with switching compatability.
I've seen articles recommending to turn off TCP offloading and to disable virtual machine queues. Is this best practice?
Any thoughts of where I might look to help diagnose this issue?

Hi ,
"1 connected to its own NIC. 1 for management and the 3 others for guests."
Also you mentioned that : " is only hosting these 24 VMs ".
First please try to disable the RSS in the property of the NICs for guests .
Then run powershell " Get-NetAdapterVMQ " to check the parameter "NumberOfReceiveQueues" (NumberOfReceiveQueues – The number of queues that the NIC has available to use and assign to VMs,
the host and a default queue) .
If I understand correctly ,when you enable VMQ the number of connected VMs on that NIC should not be more than the value of "NumberOfReceiveQueues" -2 .
For details please refer to following link:

Is there a poor network connectivity after updating to 6.1.3 ? I have updated to it and seem to have to this problem

Hi guys,
I recently updated to 6.1.3 and seem to have to have network connectivity issue. The network bar stands at 2 to 3 where as the same connection on another phone stands well at full 5 bars (at the same location).
And also App store takes ages to load.
Any remedy for this ??
P.S: I have done the basics like rebooting, cleaning history and cookies of Safari, exiting all backgroud processes, turning off location service and minimal push-notifications. But doesn't seem to take me anywhere . Kindly Suggest !!
Thanks ! Cheers !

I've had the same problem. Updated last night and haven't been able to use the phone at all since then. Black screen, grey screen, light blue screen, pixelated screen, white screen with darkened corners, flickering screen, white stripe across screen, no connectivity to anyone's computer incl bluetooth. Recurrent dead battery. Occasional apple on screen.
Dead.
Have you had any joy with yours? Or should I just bin it?

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.

Loss of wireless connection with 350n

I am having a terrible time with loss of connection with my 350 N wireless router. The router itself is on top of a bookshelf less than 50 feet away from both of my wireless desktops, and faces straight down the hallway that both rooms the computers are in open from. Often when I start up my computer it refuses to acknowledge that there is a wireless network present in the house and the only way I can make it detect it is if I powercyle the router--which is a pain. Even sitting directly next to the router it will never recognize better than 85% signal strength. And when I load (not play, just initiate loading) download-heavy content such as streaming video or an MMORPG program the connection will often drop and then reconnect seconds later. Upon performing a speed test it unfailingly indicates that my upstream is twice as fast as my downstream, which reads at only around 1165 Mbps--which is absurd as my modem is provisioned for and often surpasses 16000Mbps. What on earth is going on and what can I do to overcome it? I'm getting desperate here.

I have fixed my problem by upgrading the router firmware to version 1.03.7 from version 1.03.5.
The issue I had upgrading the router was it would fail at about 80% when using the router to do the upgrade soooooo, this is how I did it ( stolen from another thread )
Be warned! If you do the below and you have custom setting on the router you need to write those setting down first!!!!!!
1. Download tftp.exe using this link (ftp://ftp.linksys.com/pub/network/tftp.exe)
2. Download the new firmware (version 1.03.7) at Linksys download site
3. Reset your router by pushing and holding the reset button in the rear for 30sec
4. Configure a static IP address (192.168.1.50 with Subnet Mask 255.255.255.0) on YOUR PC
5. Connect a network cable from your PC to your router
6. Test that your PC is talking to the router by openning a DOS window and type "ping 192.168.1.1" (without the paranthesis) and you should get 3 replies.
7. Double click on the tftp.exe
8. Type in the IP Address for the Server: 192.168.1.1
9. Password is "password" (WITHOUT the paranthesis)
10. For the BIN file, click on the square-button and browse to the BIN file that you've downloaded from the LinkSys Site (WRT350N_1.03.7_US_code.bin)
11. Click on Upgrade
12. After the upgrade is successful, perform the reset, again. IMPORTANT!!!! PUSH AND HOLD THE RESET BUTTON FOR 30sec then let go.
13. POWER light should be blinking during boot up then stay SOLID
14. Now, change YOUR PC IP seeting back to what they were before you started this process.
15. Start InternetExploder and surf the net
16. GOODLUCK!!!
As soon as I did this, my laptop wireless started working 100% and right away.

Tcpip.sys related BSOD in Vista at either wifi/ ethernet network connection with my university

Dear all,
laptop:: Lenovo X61s 3G L7700
OS version: windows Vista business Sp1
tcpip.sys version: 6.0.6001.22167
wifi: Intel 4965AGN. Standard Gigabyte intel ethernet 82566MM
system drivers and BIOS are the most updated driver.
At my 2 homes using ADSL routers, there are absolutely no problems with network connection by wifi or ethernet. However, blue screen occurs when I bring this laptop to university and connect to the network via either ethernet or wifi. This happened to me a few months back. It crashed EVERY TIME when a network connection was attempted. It did not matter whether I updated my drivers on both wifi or ethernet cards. Whenever I bring it to either of my2 homes, no blue screen ever occurs.
It also happens when I attempt to connect to free wifi network in the airport. It crashes again with EXACTLY the same problem. I have to admit that I do not even where to start looking for the problems. System restore did not solve this either. I ran the WinBug analysis. It pointed towards tcpip.sys. My sys ver is at the top of this message.
Would appreciate if someone can point this to the right direction. I am seriously thinking of downgrading this to XP, since it had NEVER happened to XP.
thanks,
VIncent

UNEXPECTED_KERNEL_MODE_TRAP_M (1000007f)
This means a trap occurred in kernel mode, and it's a trap of a kind
that the kernel isn't allowed to have/catch (bound trap) or that
is always instant death (double fault). The first number in the
bugcheck params is the number of the trap (8 = double fault, etc)
Consult an Intel x86 family manual to learn more about what these
traps are. Here is a *portion* of those codes:
If kv shows a taskGate
        use .tss on the part before the colon, then kv.
Else if kv shows a trapframe
        use .trap on that value
Else
        .trap on the appropriate frame will show where the trap was taken
        (on x86, this will be the ebp that goes with the procedure KiTrap)
Endif
kb will then show the corrected stack.

Per my original post:
"When my ATV is connected via ethernet, and I attempt to play some internet radio stations, some will work just fine while others won't. For example, when connected to my home network via ethernet, some internet radio channels (I can't give a percentage because I haven't tested all of them) will play just fine, however, others won't. The ATV will attempt to connect, but the spinning progress bar just goes and goes and goes until it eventually errors out (no error number is provided, it just says that there was trouble loading the content). The funny thing (or not so funny thing actually) is that if I unplug the ethernet cable, and connect my ATV to the network via wifi, those same stations that didn't play when ATV was connected via ethernet, WILL play when ATV is connected via wifi. So, in short, some stations play just fine when ATV is connected to home network, through wireless router, via either wifi OR ethernet, yet some will only play when ATV is connected to home network via wifi. I have found this to be the same when it comes to downloading or refreshing the photos in my photo stream. If I throw new photos in my photo stream on iCloud, and the ATV is connected via ethernet, they won't refresh to the ATV, however, if I unplug the ATV and connect via wifi they begin to refresh."
There are dozens of original threads out there that report of similar - if not exact, issues. I have contacted "Roy" per his request and not heard back from him (if such a person exists). I have "restored" my ATV and rebooted all equipment to no avail. Until Apple gets with it, acknowledges their problem, and fixes it, I am resigned to just having to deal with switching back and forth from wifi to ethernet, and so on.

Loss of network connectivity

I have a Macbook that is just over a year old.
My wireless connection infrequently hangs, and i have to either restart my router (Belkin 54g) to get it going again. I cannot reliably recreate the hanging, but it does tend to happen when I am downloading large files or watching streaming video - the other day I had to restart my router 6 times just to check my email!
As I say I tend to notice the problem either downloading podcasts or other files through safari by noticing the throughput falling. The way I confirm i have a problem is to open Safari - I try to connect to a reliable website (such as news.bbc.co.uk) and the the blue progress bar stops after the " http://" - eventually timing out with an error of "Safari Can't connect to the server."
I have tried restarting my Macbook, enabling disabling my airport connection, but it made no difference. The only way I could it it going again was to reboot my router. So presuming it to be a problem with the router I replaced it.
I obtained another router (Linksys N) and all seemed ok initially but even that has now shown the same problem. Trying to download a file this week I discovered I could nudge it a long by switching between the 2 different wireless networks/routers now have to download the file.
I have tried clearing out system cache's, deleting and recreating network connections, even reinstalling OS10.5 (but keeping user accounts), and it still seems to be happening.
I have run Apple hardware test, and no errors have been found.
I've checked my log files but nothing seems to stand out as being a problem, but i don't really understand what I'm looking at!
Unlike other reports, my network connectivity and signal bars are all ok - I can even connect in to the router console, but i can't connect out to the internet.
Does anyone have any ideas please? What can i look for in the logs ? Is there someway to check to see if its a problem with my built in Airport card?
Thanks in advance.

You have my sympathies....
A few things I guess but not necessarily in this order or everything:-)
-Removed non Alpha characters from my SID
-Changed the cable from my modem to my router
-Reset my Modem and checked all other connections
-I gave my account Admin permissions while I running updates and tidy ups (which reminds me I must change it back)
-The tool I used to clear caches etc was a freeware download called Onyx (http://www.titanium.free.fr/pgs2/english/onyx_leopard.html) based on a recommendation I heard in a podcast - take backups and use at own risk
-Minimised the channel clashes with other routers and switched other wireless devices/routers off that could conflict.
-Tidied up any dead or unnecessary connections in Network System Preference panel, and made my Network to the top!
-Installed update to iStat Pro 0 you might try un-installing and reinstalling
Good luck

Lost network connection after update

I waited a little long to update (~4 months) and am paying the price. The recent update broke X as well as my network connection (and who knows what else!). When I type ls /sys/class/net/, all I get is lo@. I'm a little rusty with Arch as I was really really busy with school. Do you have any suggestions for fixing this? Here is my rc.conf if it helps:
LOCALE="en_US.UTF-8"
DAEMON_LOCALE="NO"
HARDWARECLOCK="UTC"
TIMEZONE="US/EASTERN"
KEYMAP="us"
CONSOLEFONT=
CONSOLEMAP=
USECOLOR="yes"
VERBOSE="3"
MODULES=()
UDEV_TIMEOUT=30
USEDMRAID="NO"
USEBTRFS="NO"
USELVM="NO"
hostname="srv"
interface=
address=
netmask=
gateway=
NETWORK_PERSIST="no"
DAEMONS=(hwclock syslog-ng network netfs crond gpm bitlbee dbus sshd)
Anything else I should post? Thanks for your help!

I was on vacation for a week, but now I'm back.

Unfortunately, I cannot paste in these directories because it appears that usb is completely shot as well and I don't have a floppy drive (nor a floppy for that matter). At least, I believe so because I stuck in a stick and ran:
dmesg | tail
and didn't see anything about a usb being registered by the system.
Neither ifconfig or ip are installed. So that is also a considerable issue. Is all hope lost other than getting a live CD of ubuntu, spending a day copying files off of the hard drive and reinstalling?
Sorry, I must have been really tired when I typed this. Both programs (ifconfig, and ip) are in /sbin/. I'm betting I tried 'sudo su' and they weren't on the path and being out of it, I assumed the wrong thing. I'm going to try and mount a usb again to see if I messed that up as well...
I still don't have an eth1 or eth0. But maybe all hope is not lost.
Update:
No device nodes are created in /dev/ for usb drives, and my computer won't even power them unless I do it at boot. I also noticed that my keyboard doesn't work at all during grub.

I am wondering if the kernel on the boot partition somehow did not get upgraded when we moved up to 2.6.2939
Yeah it does. So no luck there.

LaserJet Pro 200 color MFP m276nw no network connection with Linksys HUB

Hello
I've setup my LaserJet Pro 200 color MFP m276nw to connect to my home network using a wired connction.
When connected directly to my router the connection initializes and successfully recieves an ip address. I've been able to access all the network function connected to my router directly either wired or wirelessly.
I also have an old Linksys hub and when the printer is connected to the hub, it does not initialize the network connection. The hub works with every other sevice in my network, including a few game consoles and a Mac Mini.
Is there an advance network setting I should be looking at?
Thank you
This question was solved.

Hi,
Remove any wired connection before attempting to connect via wireless.
Print off the printers network configuration and check the settings against your routers settings.
Ensure that router and printer are using the same frequency.

T410 loss of network connectivity - Packet Scheduler Miniport driver

Hi
Our organisation has recently received its first shipment of T410 laptops. After installing our XP SP3 build we're experiencing an issue whereby the laptops are working pefectly, but after a shut down, the next time the device is powered on network connectivity is lost. In device manager, adjacent to each network adapter device, a new device appears for 'Packet Scheduler Miniport' and each of these has a yellow exclamation mark indicating the device us unavailable.
Rebooting the laptop sometimes resolves the issue, the packet Scheduler Miniport devices disappear from device manager and network connectivity is restored. However, after a subsequent reboot the problem returns. We've tried reflashing the system BIOS but affected machines have the most recent version (1.25, 07/03/2010). We've also tried downloading the relevant network driver directly from intel and installing to no avail.
We've been unable to spot any pattern to the fault occuring, it appears to be completely random. has anyone else experienced similar issues with an XP build on the T410? My searches have brought up similar issues relating to the Packet Scheduler Miniport but nothing specifically in relation to the T410. It's worth noting our build for the T400 contained the same application suite and we haven't had a single issue like this throughout the life of that model.
Any help on this is greatly appreciated
Thanks
Solved!
Go to Solution.

Hi I just found your posting regarding the same exact issue I had. The way around this issue is to go to device manager select the Intel adapter for lan and un install it but without removing the application just uninstall the drivers when finish click on scan for new devices and when done you will have a connection it seems like some of the windows 7 libraries clashes with the adapter libraries and fail to acknowledge one to the other.
Hope this helps

Message loss during network connection reset

We are planning on using Oracle streams for async notifications between the database and our Java application. While testing for some edge cases we are running into the following issue.
1) Start Java code(Waiting to dequeue message) -> disconnect network -> queue new message(using SQL) -> connect network ==> We are loosing the message in this scenario, even if we restart the listener the message would not show up.
2) Start Java code(Waiting to dequeue message) -> disconnect network -> connect network -> queue new message(using SQL) ==> This scenario works.
DB stores messages if the listener is not running, but if we start the listener and disconnect network connection somehow the database thinks it delivered the message.
Also is there any way to stop blocking dequeue call during connection drop, database shutdown/restart?
We are using the point-to-point model, messaged is enqueued from a trigger that gets fired on insert/update to a particular table and we have a MessageListener that Uses Java API to dequeue the message. This code works fine during normal operation.

AQ uses persistent storage in queue tables so the first thing to do is see if the messages got into the table.
If they did what is the status? If not the issue is likely that your code never got the messages to the database.

Cannot obtain network connection with Clear modem. Is there a special trick to get beyond the blinking amber light?

My connection follows this chain:
Clear modem to telephone router
telephone router to network router (in this case I am attempting to set up the AirPort Express in this place).
so I have opened up the Airport Utility and didn't have any luck with getting the Network Connection to turn green and subsequently the AirPort Express is not completing the handshake with the network to get fully connected.
I've gone back to a Netgear router in the meantime and that gets the conection right away. I have only Mac computers connecting to the router and one Epson printer that will connect wirelessly.
Any advice or experiences with this setup would be appreciated. Thanks.

I got the support I needed directly from Apple. It turnsout to have had zero to do with Clear. I had named the new AirPort network the same as the previous network and we concluded that it was making the new settings confused. I did a hard reset, renamed the network to a completely unique name and we were off and running. Thanks Apple!
