Lost network connection after SW update

First time poster, relative newbie to Mac. I blindly updated to 10.4.11 and then found that my Mini had no network connection, yet my Ministack external FW HD and WinXP (thru BootCamp) will still connect wirelessly to my Westel router which has not been touched throughout this ordeal. My network is still shown and even offered to me for use during boot, but fails to connect. I have thrown every switch I can find in sys prefs to no avail. I have been asked for a WEP password, but security is switched off (in prefs and router), and I never used a PW before. I've spent hours Googling this topic, but can't find an exact match to my situation. I don't have the Mac knowledge to undo the update, or even know if it can be done. I can't understand how the bootable external HD can share the connection, but the "host" computer can't use it. Gotta be a setting wrong somewhere, eh? Please help.

A warm welcome to the forums!
Tons of similar posts, but not too many with the same cause fix.
If you haven't done regular maintenence like Disk validate/repair, Permissions fixes, etc, ete.
Then you Might give a try with Applejack...
http://www.versiontracker.com/dyn/moreinfo/macosx/19596
After installing, reboot holding down CMD+s, then when the prompt shows, type in...
applejack AUTO
Then let it do all 5 of it's things.
At least it'll eliminate some questions if it doesn't fix it.
The 5 things it does are...
Correct any Disk problems.
Repair Permissions.
Clear out Cache Files.
Repair/check several plist files.
Dump the VM files for a fresh start.

Apple TV2 can't find my network connection after recent update?

Why can't my Apple TV2 can't find my network connection after recent update?

I had to update the software on my Airport Extreme then reset my apple tv and that resolved the issue for me.

Fascinate lost network connection after last Froyo update.

Anyone know how to fix this issue. After updating to the knew froyo upate last month my sons phone lost network connection and won't connect. It doesn't even show up in the settings for him to be able to connect. He can still make calls and connect but nothing data wise. Plus he still gets missed calls so that update never worked for him either. Please help and thanks.

I understand how frustrating this must be. My personal device had this problem and I found a solution that worked for me. Hopefully it will work for you as well.
1. Put the device in Airplane mode (hold power button and select airplane mode)
2. Wait 3 minutes for changes to take effect. You should see the airplane icon in the notification bar as well as the airplane lock screen.
3. Power the device off and wait 15 seconds.
4. Power the device on. Once sense loads, turn airplane mode off.
5. In the settings>Wireless & Networks Menu, check the box entitled "Mobile Network"
6. Everything should re-provision and data should be restored.
If the steps above do not resolve you issue you may want to try a master reset. Resetting the phone deletes all data, including downloaded applications, and resets the phone back to its initial state—the state before you turned on the phone for the first time.
Important: Make sure to back up important data you have on the phone before you reset your device.
Master Reset:
From the home screen, touch Menu
Touch Settings
Touch SD & phone storage
Touch Factory data reset
Tap Reset phone
Tap Erase everything
Reset may take anywhere from 1 - 10 minutes for reset and restart depending on amount of data on device.
I hope this information has been helpful.

Lost network connection after standby on Satellite P200

Hi
Laptop Satellite P200
OS VISTA 32
When I stop working with laptop I usually close monitor and when next time open laptop computer lost network connection.
Then I have to renew IP config and internet start working.
Does anybody know why and how to avoid this?
End I still want to use standby options.
Tnx for any idea
Sandi

Hi
In your case I recommend updating the BIOS and to enable the option Wake up on LAN in BIOS and in the Vista.
In Vista you can enable this in device manager -> LAN card properties -> Advanced tab
Additionally a LAN driver update would be advisable.

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"

TIMEZONE="US/EASTERN"
KEYMAP="us"

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.

Satellite Pro U400 - Lost network connection after suspend

I have a Toshiba Dynadock. My network is connect directly in dynadock.
When suspend my Satellite Pro U400 and after restart for continue working I lost my network connection. Then I shutdown my computer and disconnect/connect Dynadock I can continue working.
What's the problem?
Version software Dynadock is 2.0

Hi
I see you have switched from Vista to XP.
First of all I recommend updating the BIOS.
As Im not mistaken you should find a newer BIOS version on the Toshiba European driver page.
Then you have to update the Win XP to the latest state!
The XP should be up to date and all service packs, patches and MS fixes should be installed in your notebook.
Then access the device manager and mark in every USB root hub you have to disable the option called Allow the computer to turn off this device to save power
You can find this option in properties -> Power management tab

Help - lost network connection after firmware upda...

I just updated the software for my 5500, and while it isn't 'dead', it no longer picks up a signal (ie: no bars). I've tried two sim cards, and neither works. I've tried setting the network operator manually, but no luck there, either - it recognized the network once, but never after that. I'm using att in the virgin Islands, which worked perfectly before the update. Any hints?
Thanks!

I finally called Apple and reset the Airport. It's working again.
Thanks, John. Yes, I could see my network in the Airport menulet, but the Airport couldn't see the internet. In the Airport Utility the DHCP address appeared correct, that is, assigned by my service provider. The router IP address was 10.0.1.1 and my laptop was 10.0.1.XXX.
If I plugged the modem directly into my computer and renewed the DHCP license it would work. As soon as I moved it to the Airport and rebooted the Airport there was no internet access via Ethernet or WiFi. I tried rebooting everything at least a dozen times.
I called Apple and reset the Airport with a paper clip. I had to re-enter all of my information, network name, password, etc. I got a configuration error the first time I hit "update" but after another reboot it worked. We also turned off my cable modem for at least five minutes.
I wish I'd thought of resetting the Airport (instead of just rebooting).

Photos/videos in the Camera Roll are not synced. Photos/videos in the Camera Roll are not touched with the iTunes sync process. Photos/videos in the Camera Roll can be imported by your computer which is not handled by iTunes. Most importing software includes an option to delete the photos/videos from the Camera Roll after the import process is complete. If is my understanding that some Windows import software supports importing photos from the Camera Roll, but not videos. Regardless, the import software should not delete the photos/videos from the Camera Roll unless you set the app to do so.
Photos/videos in the Camera Roll are included with your iPhone's backup. If you synced your iPhone with iTunes before the videos on the Camera Roll went missing and you haven't synced your iPhone with iTunes since they went missing, you can try restoring the iPhone with iTunes from the iPhone's backup. Don't sync the iPhone with iTunes again and decline the prompt to update the iPhone's backup after selecting Restore.

Lost data connectivity after upgrading iPhone 4 to iOS 5. How to fix?

Hello,
I upgraded my 16GB iPhone 4 yesterday from iOS 4.3.5 to iOS 5 and everything went fine after a few failed connections to Apple's servers, however my phone lost the data connectivity completely. Phone and SMS worked fine, I could also connect through wi-fi with no problems, however whenever I tried to use data I got a message that my phone was not signed to an internet service.
I restored my phone from the backup after upgrading. Not successful. I also reset the network configurations. No deal.
My carrier is Vivo (Brazil) and everything worked fine prior to the upgrade (and after the downgrade).
I imagine it can be a problem with APN configuration under iOS 5 and I tried to configure it through a webpage, but I got a message that my phone already had a APN config (profile) and could not install another. Under Settings>General>Network I don't have the "mobile network option" nor the "profile" option.
Any thoughts? So far I haven't contacted other people under my carrier who upgraded to see if they had the same problem.
Thanks for reading,
Samuel

I got a workaround; it's not what I wanted, but it solves the main problem.
I noticed that I only lost data connectivity after restoring from backup after the iOS 5 update. So what I did was to backup my phone, restore again to iOS 5, configure as a new phone and backup again (with nothing in the phone).
Then I launched an iPhone backup utility software, in this case, iBackupBot, which in the trial version is enough for what I wanted. I opened the old backup and exported only the files I wanted (like call history and SMS history), then I imported these files into the new backup and restored from it.
I lost my media files (which I copied before) and some configurations, but the most important itens, like SMS, I managed to export from the old (complete) backup.

Removed ip access-list & lost network connectivity

An access-list was removed to edit and replace. Once the access-list was removed we lost network connectivity to the remote router. This list is an extensive one. But when we remove on other remote routers network connectivity remained. Can anyone tell me why? Is this a typical of access-list, and good practice is to wait until after business hours?

No problem.
I am sure that we have all had experiences of looking at things we have written, or questions answered, and realized that what we wrote was not quite what we were thinking as we created it.
Your main point is well taken that it is good practice to remove the access-group before removing and changing the content of access lists.
Sometimes I take a slightly different approach: I will build a new version of the access list using a different number (if I am changing access list 101, I may create list 102) which is the modified version of the list. I then change the access-group to reference the new version of the list. This may have a couple of advantages including the fact that the interface is always protected by some access list. Also it makes backing out changes easier if we discover that there was some flaw in our list modification.

FP1600 loses network connection after a few hours

My FP1600 loses its network connection after a few hours. It is part number 185690C-01, with firmware 4.11. I am running FieldPoint Explorer version 3.0.1 and LabView 6.1 from Windows XP Professional. I set it up, and everything runs fine for 4 hours or more. I do not have the network watchdog enabled, and the FP1600 is in constant communication with the host computer in any case. Sometime in the middle of the night the communication is lost. The FP1600 link light
is on, and it is still receiving packets, but it will not respond to a ping or any other communications. Only a power cycle brings it back. The FP1600 is sitting right next to the host computer, both attached to the same network switch. There is no interruptio
n of network services to the two.

Hi Heinz,
We are also trying to troubleshoot this same problem (Intermitten network connection loss with FP1600 Ethernet Module - Error code "33163", Error Message - "FP1600 Connection to module has been lost."). We have checked other possible causes for this sort of behaviour. Including independent assessment of netowork availability at the time of error reporting, connecting dedicated power supply to the FP1600 module, temperature of cabinet housing the module (which is between 10 and 50 deg C), disconnecting sensors connected to various I/O modules connected to this module, increasing duration of parameter "time out" (the time module will wait before reporting an error if it can not access network). However, none of the above resolved the intermittent and random network loss errors.
The MAX version is 3.0.2, and the firmware on the module is 4.17, Labview version is 7.0 and the Operating System is windows NT.
I was wondering is there any information about this problem from any user or NI recently. The only solution looking in to this discussion forum seems to be replacing the module.
