Strange Connectivity Issues

Hi,
I have an iMac 27" Intel i5 running 10.6.6 and for some reason I have been getting some firewire devices not being recognised. But for some reason my Macbook Pro which also runs 10.6.6 finds with no problem at all connecting to them.
For example my laice external lightscribe drive which was running just fine on my iMac until recently can only be found now on my Macbook. So I'm not sure what changed, could it have been a recent update? Or a driver issue since 10.6.6?
The other thing that works fine on the macbook and not my iMac is my old MiniDV Sony handycam.
My time machine backup and Sandisk DF card reader work just fine through the same firewire port so I am quite confused.
Any help is much appreciated.

Strange connection issue's since Early August

Since August my normally flawless BT connection (virtually zero downtime or speed loss in 2yrs) has gone kaput. At the moment my connection struggles to play 360/720p vids and during online gameplay my MS is either high or when its low the connection lags.
I have been speaking with BT tech since Aug trying to isolate the issue and they have done line tests etc etc and the problem has not sorted itself out yet. After another phone call today where I requested an engineer to come take a look I was suddenly told that there is an outage on my line and that I have to wait another week or so to see if my connection stablizes.
Now this could be genuine or just a fob off either way I cant do much about it other than ask you guys if there is anything more i can do from my end.

Additional notes
I factored in the possiblity of it being the holidays still and primetime usage but I have had this before and not had problems on this scale.
Another factor is that I changed hubs from 2-3 and the problems seem to have started since then.
During tech calls my speed was reduced to what it is now from 7mbs
Solved!
Go to Solution.

when eventually BT get round to sending the email about the upgrade then it will be auto but that may take months.
Tech are also correct that your profile is set by your current speed and is therefore correct. The point is as your exchange has been upgraded it is possible to get the upgrade early before the 'auto' but you need to agree a new contract.
There are numerous similar posts on the forum like yours where after agreeing a new contract and reduced cost they got the upgrade to 21CN and faster speed.

Strange connectivity issue with WRT54G

I hope you can help with this. I have just moved into a new house and am trying to connect the internet through their WRT54G wirelessG router. It shows up with full reception in the WindowsXP wireless connection manager, but it will not connect. IPCONFIG has its status as 'Media Disconnected', and all pings to 192.168.1.1 fail. A loopback test ping to 127.0.0.1 works. My flatmate's wireless connection to same router works fine, and when he accesses the router's configuration page it states that I HAVE connected and DHCP has assigned me an IP. I've tried everything; deleting & resetting the connection, resetting the TCP/IP/Winsock protocols, disabling the WEP security on the router, but no luck. The connection is fine on my flatmate's computer. My machine is a Dell laptop and and I have taken it to 3 other wireless networks and it connects to them no problem. I can connect to the router in question fine wired with a CAT5 cable but it's not convenient to have that as a permanent solution (when the router is supposed to be wireless!)
I work in IT and thought I was pretty good with computers but this has me completely stumped! I looked for new firmware but couldn't find any listed on your site - if there is could you provide a link, or if you've any other ideas what could be causing this please let me know!
Thanks

Sounds to me like it's related to a configuration setting despite the "Media Disconnected" message. Try disabling any SpeedBooster or other non-essential options on the router. Perpaps the Dell WiFi NIC doesn't like it. I doubt it's a MAC filtering issue but you can try removing that too. If it's a somewhat older laptop you can try removing the small panel on the bottom and reseating the WiFi adapter if it's located there. Newer Dells have them built in around the LCD where you can't access them.

WRT54G Strange connection issue when wireless security is enabled

The model # is WRT54G v2.2 with firmware 4.21.1. I knew that my internet connection was good because I connected my laptop directly to the wireless antenna. When the antenna is connected to my wireless router I can't connect, wired or wireless. I decided to reset the router and program back in the changes that I have made. I checked for internet connection after the reset, it's there. Made more changes, still good. Then when I enabled wireless security using WEP the wired and wireless internet connection goes away. Any ideas to fix this. Can I go back to the previous version of firmware?

hi... go to ftp.linksys.com/pub/network and try downloading older firmware for the router and downgrade the firmware, after that reset the router back to factory default settings and reconfigure it...

Strange connection issue.

I've gone threw the post here and can't find anything referring to this.
I'm on tour with a total of 7 other Mac users. Every other venue or hotel we go to, at least one or two of us will have this problem (it rotates).
All but one of us is able to connect to the house wireless system (the one person who can't connect changes all the time). We are all using DHCP, so getting the IP addresses auto assigned. All the computers have no problem getting the IP add's (including the machine of the day that won't be able to get on) Most of us are running 10.4.5 but some are still on 10.3.9 (this seems to make no difference). All permissions have been done, firewalls shut off, and updates checked.
Any Ideas?
Much Thanks, Kal

Kal,
Could you be more precice?
What is the problem? Some of the computers self assign an ip address that doesn't work with the network? Or some get addresses and web browsing (or DNS or mail) do not work?
I can assure you - firewall isn't related - turn it on unless you're sure you don't want or need it.
Lastly are you using AirPort wireless or a wire to connect to the networks. (or does that make no difference)

HP PhotoSmart 7510 suddenly has severe connectivity issues

I have a HP PhotoSmart 7510 printer since about 2 months. Initial setup worked like a charm and the printer has been working pretty much perfectly for the last 2 months. Wireless printing, scanning and internet access on the printer (e.g. for Facebook photos) all worked. Just from time to time i would get the occasional (mildly annoying) message on my computer saying "scan to computer is currently unavailable" but it usually worked itself out and whenever I needed it to work, it did work.
But since a few days ago, it has some severe connectivity issues. I didn't change any settings on the printer, router or computer - the issues just started appearing by themselves. I startet getting much more frequent messages on my computer saying "scan to computer is currently unavailable". I noticed I couldn't print anymore, and restarting computer, printer and/or router didn't help at all. The only thing so far i managed to print wirelessly since the problems started were the first 5 pixel rows of an image I tried to print, the rest didn't transmit.
It seems the printer still connects to the WLAN but printing and scanning no longer work, and whenever I try to access a web service on the printer (like Facebook) it says it has no internet connection, even though the WLAN light is lit up (not blinking) and all the wireless status reports say "congratulations, no problems found" and display IPs etc. just like normal.
I looked at the threads "PhotoSmart 7510 connects to router, but not to the web.", "Wireless printer (HP Photosmart 7510) not connecting to network" and "Photosmart 7510 won't connect to Web Services" but they weren't a big help. Activating EWS didn't work because even though the printer showed its IP address to be 192.168.1.3, when I entered this in my web browser it didn't find the printers configuration page.
I tried the following steps from one of the threads:
1. Restore the Network defaults
2. Unplug the printers power cord while it is still on. Leave it unplugged and walk to the router.
3. While the router is still on, unplug the power cord from the router, leave it unplugged for 30 seconds, then reconnect the power cord to the router. Once plugged back in the router should power on automatically.
4. Plug the power cord back into the printer. Once plugged back in the printer should power on automatically.
5. Run the Wireless Setup Wizard to reconnect the printer to your wireless network.
6. Try enabling Web Services.
I followed these steps exactly. Interestingly, even though I had done step 1 and restored the network settings to factory defaults, after turning back on, the printer somehow still had its old settings saved and reconnected to the network.
It seemed to have fixed the problem, the printer finally had internet access again (Facebook app showed my photos) and scan to computer found my PC. But after just about 3 minutes, the printer had lost its internet connectivity again. When opening the Facebook app, it displayed the same error message it did before. And printing no longer worked as well.
So, what is wrong with this printer?! It has the newest software update by the way (I checked during the 3 minutes it had internet access.) My computer is a HP Windows 7 x64 machine (EliteBook 6930p) and the router I'm using is a Netgear WNDR3700.
I specifically bought this printer for my studies at university. In one week i have my exams and in order to study I REALLY need to be able to print some of my course materials! So any help as quickly as possible would be greatly appreciated. Or do you think this is a case for a warranty replacement, considering the printer's really strange and error-prone behavior?
Thanks a lot!

I can assure you that it is not a router issue. It appears to me that it is a driver compatibility with Windows OS. After trying to get to the bottom of this since my Photosmart 7525 was new and reading just about every forum and blog, I have come to the conclusion that the issue must be related to the HP driver itself.
The issue does not seem to affect any Mac systems, and from one forum someone was able to fix it by downloading new drivers compatible with 64-bit systems (which seem to not be affected by the glitch). But that leaves us 32-bit people stuck with the current driver which does not work.
The printer is connected with good signal to the wireless router (no matter who's router it is and what configuration is made). The printer can be pinged from the router and any computer on the network which is not currently being affected by this issue. However, the affected computer fails pings by either request timed out, or destination host unreachable. Pings are successful from the affected computer to any other device on the network. The only way to recover (at least for a few days) is to reboot the affected computer.
Also, from the display on the 7525, the network tests pass without issue. I can also download and print content from the internet with no issues.
Please do a quick google search of this issue and you will see several THOUSAND entries of people with the same request. This is a serious issue that people are having and everything is pointing to an HP problem (not routers, improper installation of software or drivers, etc...). I agree with several other customers that HP should be on the hook for this fix. I will give it another couple weeks, then back to the store for a reliable unit from another competitor (Canon, Lexmark, etc..)
Thank you in advance for escalating this issue to product engineering,

Strange performance issue with 3510/3511 SAM-FS disk cache

Hi there!
I'm running a small SAM-QFS environment and have some strange performance issue on the disk storage part, which somebody here might be able to explain.
Configuration: one 3510, dual controller, RAID-5 9+1, one hot spare and one disk not configured for whatever reason. The R5 logical drive hosts a 150GB LUN for SAM-QFS metadata (mm in SAM-FS speak) and a 1TB LUN for data (mr in SAM-FS speak). Further, there are two small LUNs (2GB, 100GB) for some other purpose. Those two LUNs have nearly no I/O. All disks are SUN146G. Host connection is 2GBit, multipathing enabled and working.
Then the disk cache became too small, and the customer added a 3511 expansion unit with SUN300G disks. One logical drive is a RAID-1, 1+1, used for NetBackup catalog. The other is a RAID-5, 8+1, providing two LUNs: 260GB SAM-FS metadata (mm) and 1.999TB SAM-FS data (mr).
For SAM-FS, the LUNs form two file systems: one "residing" in the 3510, the other "residing" in the 3511 expansion. Cabling is according to the manual and checked several times by several independant people. Operating system is Solaris 10, hardware is a V880.
The problem we observe: SAM-FS I/O on LUNs on disks inside the 3510 is fine. With iostat, I see 100MB/s read and 50MB/s write at the same time. On the SAM-FS file system which is running on the two LUNs in the 3511, the limit seems to be at 40MB/s read/write. Both SAM-FS file systems are configured the same in regards of block size.
In case I have activity on both SAM-FS file systems, I see 100MB/s+ on the LUN running inside the controller shelf and another 40MB/s on the disk runnin in the 3511 expansion chassis. So, the controller is easily capable of handling 150MB/s.
Cache settings in the 3510 controller are default I think (wasn't installed by me), batteries are fine.
Is this 40MB/s we experience a limitation by the expansion shelf? Don't think so. Anybody has any ideas on this? What parameters to check or to change? Any hint appreciated. I can also provide further details if needed. Thank you.
wolfgang

SUN300G disks sound like 300GB FC disks.
Depending on how many files are in the SAMFS file system, sharing the mm and mr devices on the same RAID array can be a pretty horrible idea. In my opinion and experience, it's almost always better to NEVER put more than one LUN on a RAID array. Period. Putting more than one LUN on an array results in IO contention on that array. And large, unnaturally configured (9+1? Why?) RAID arrays will have problems from the start.
What are the block sizes used on the RAID arrays? It wouldn't surprise me to see that the RAID array on the expansion tray has a very large block size. Larger block sizes are, in general, not better. Especially for SAMFS metadata - which IIRC is something like 8k or 16k blocks.
I suspect what is happening is most of the metadata updates are going to the mm device on the new array, contending with the IO operations on the file data.
How much space is left on each mm device? What does "iostat -sndxz 2" show when you're having the IO problems?

Connectivity issues for random phones in CUCM 8.6 on Vmware

I have a client that has problems with around half of there ip phones (6921 & 7945) after a situation with overheating in the serverroom.
The solutions was a 1 Publisher, 1 subscriber setup with each on a separate Vmware server.
The Publisher is connected to the Core Switch which is further connected to 4 distribution switches which again connect to 5 more distribution switches. They have around 200 ip phones connected to these switches that get assigned IP's with DHCP.
The physical disk that the Subscriber was on was destroyed the incident. The Publisher they recovered, but to do this they had to recreate the vm descriptor file and attach it to the flat-file.
So the current situation is that the system is running with only 1 Publisher and no Subscriber.
There is also a license warning in the CCM Admin section, stating a License Overage (2 nodes used, but only 1 licensed.)
The license status is not invalid though, and the license state is "Uploaded". This second node I suppose might be the Subscirber that no longer exists? The phones have more than enough licenses.
When powered up the system seems to run as it should, but only about half the phones have connectivity to and can register with CUCM.
I have tried to reboot some phones remotely by cutting the power on the switch interfaces where they are attached, but that made no difference.
The console log on the phones that are down show TFTP Timeout & File Transfer Error.
The phones that are up and running can be pinged successfully from the CUCM cli, but when pinging the others I get "Destination Host Unreachable".
The strange thing is that it seems completely random as to what phones are up or down. On all switches there are connected phones with both working and non-working connections to CUCM.
To try to pinpoint the fault I chose 2 devices on the same switch and compared the config for each interface, one that has connectivity and is registered, and one that does not have connectivity and is unreachable.
Everything seems to be identical so I can't see what causes this error on the one, but not on the other.
Also when I ping the ip phone with no connectivity to CUCM from any of the switches, the ping is successful.
Anyone know what could be the cause of this behaviour?

Hello and thank you for your time.
The phones get there IP’s from a DHCP Server (Not the built in one in CUCM, but an external server). I have tested that the DHCP process works by powering off a phone (one of the phones with connectivity issues), deleting the lease, and then powering the phone back on and seeing the device request and receive a new lease.
There is only one CCM group active and both servers are in this group with the Publisher as highest priority server. All phones are in the same Device Pool attached to this group.
There are a lot of warnings regarding dbReplication & missing node due to the subscriber being gone. Also there is an issue with NTP server (see below). I will post more on this tomorrow morning.
I have also attached the console log from one of the phones that can't register.
NTP Alert:

N8 Connectivity issues post Anna

I was wondering if anyone was having connectivity issues with your N8 after Anna has been installed. Ive dont the simple things with the settings in the search options. I seem to still have issues getting a connection unless there is a 100% full signal. Anything less, the phone just hangs. Sometimes for 60-80 seconds before a webpage is loaded. Is this a bug within Anna?
Thanks in advance for any help. And Happy Holidays to everyone.

Have not tried with Direct Ethernet connection, but after restarting my iMac a couple times it strangely worked. Updating software now, well still downloading @ this point. Thought it was possibly the security type I was using, but I ended up back to WPA2 personal that I had originally started with. It was not even seeing my WiFi before, so I never even had a chance to enter a password. Also using an older AirPort Extreme. May be time for some updated equipment, but at the same time it has made it this far.

Troubleshooting for RPC over https (Outlook Anywhere) connection issue

RPC over https (ROH), well known as Outlook Anywhere, is more frequently used. Even in Exchange 2013, Outlook no longer connects CAS server via MAPI.
In this thread, we will discuss about the troubleshoot checklist about the RPC over https (Outlook Anywhere) connection issue. In order to make it more logical, I’d like to divide the whole troubleshooting to the following processes:
1. Client side to CAS side
2. CAS side to MBX side
[Issues between Client side to CAS side]
In Exchange 2013, Outlook Anywhere is enabled by default. Different from this, Outlook Anywhere in Exchange 2007 and 2010 need to be manually enabled. Thus, please firstly check if the RPC over HTTP component has been installed:
Click Start, and then click Control Panel.
Double-click Programs and Features.
In the left pane of Server Manager, click Features.
In the right pane, click Add Features.
Check if the RPC over HTTP component has been selected.
If the ROH connectivity issue only happens on certain users, the property MAPIBlockOutlookRpcHTTP can be checked:
Get-CASMailbox name | fl MAPIBlockOutlookRpcHttp
2. Confirm if Exchange server is blocked. Ping the Exchange server FQDN on client machine and confirm if it can return the proper IP address.
3. Check if the RPC Proxy server is responding correctly:
rpcping -t ncacn_http -s ExchServer -o RpcProxy=RPCProxyServer -P "user,domain,*" -I "user,domain,*" -H 2 -u 10 -a connect -F 3 -v 3 -E -R none
If 200 code returns, the test is successful.
4. Check if Outlook Anywhere host names are added in the certificate:
To get host names, the following command can be used: get-outlookanywhere |fl *hostname
5. To use the Shell to test Outlook Anywhere connectivity, use the
Test-OutlookConnectivity cmdlet.
[Issues between CAS side to Mailbox side][RZ1]
A. Check if it can connect to store’s port:
RpcPing –t ncacn_http –s ExchangeMBXServer -o RpcProxy=RpcProxyServer -P "user,domain,password" -I "user,domain,password" -H 1 –F 3 –a connect –u 10 –v 3 –e 6001
If it returns as following: Completed 1 calls in 60 ms 16 T/S or 60.000 ms/T, it means the RPC Ping Utility test succeeds.
B. Check if it can Connect to DsProxy Service:
RpcPing –t ncacn_http –s ExchangeMBXServer -o RpcProxy=RpcProxyServer -P "user,domain,password" -I "user,domain,password" -H 2 –F 2 –a connect –u 10 –v 3 –e 6004
If it returns as following: Completed 1 calls in 60 ms 16 T/S or 60.000 ms/T, it means the RPC Ping Utility test succeeds.
C. Check the following registries:
[Disable the auto update]
1).Open Regedit and navigate to:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MSExchangeServiceHost\RpcHttpConfigurator\RpcHttpConfigurator
2).Set the PeriodicPollingMinutes value to 0.
[Check the RpcProxy ValidPorts]
1).On the RPC proxy server, start Registry Editor (Regedit).
2). In the console tree, locate the following registry key:
HKEY_LOCAL_MACHINE\Software\Microsoft\Rpc\RpcProxy
3). In the details pane, right-click the ValidPorts subkey, and then click Modify.
4). In Edit String, in the Value data box, type the following information:
ExchangeServer :6001-6002; ExchangeServerFQDN :6001-6002; ExchangeServer :6004; ExchangeServerFQDN :6004
Note:
ExchangeServer is the NetBIOS name of your Exchange server. ExchangeServerFQDN is the fully qualified domain name (FQDN) of your Exchange server. If the FQDN that is used to access the server from the Internet differs from the internal FQDN, you must use
the internal FQDN.
[Check the 6004 port settings in registry]
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MSExchangeSA\Parameters
Value name: HTTP Port
Value type: REG_DWORD
Value data: 0x1772 (Decimal 6002)
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MSExchangeSA\Parameters
Value name: Rpc/HTTP NSPI Port
Value type: REG_DWORD
Value data: 0x1774 (Decimal 6004)
D. Check if the RPC ports are used by other applications instead of Exchange by using : netstat –o
Then it will return all active TCP connections and the process ID (PID) for each connection.
After that, please check the application based on the PID on the Processes tab in Windows Task Manager and confirm if it’s Exchange server.
Additionally, ExRCA is a perfect tool to test the whole connection between client side and Mailbox side:
https://testconnectivity.microsoft.com/
1. On the ExRCA website, under Microsoft Office Outlook Connectivity Tests, select Outlook connectivity, and then select Next at the bottom of the page.
2. Enter the required information on the next screen, including email address, domain and user name, and password.
3. Choose whether to use Autodiscover to detect server settings or to manually specify server settings.
4. Accept the disclaimer, enter the verification code, and then select Verify.
5. Select Perform Test.

I've just restored the M11 to Windows XP with the disks provided and Outlook Anywhere connected without issue. As strange as it sounds, this looks to be isolated to this particular model of laptop and Windows 7.
I've used the same Enterprise copy of Windows 7 and Office on a variety of laptops and pc's and none have come across this problem. The only commonality I can see is the hardware and OS.
Aftery trying to troubleshoot this unsuccessfully with Microsoft tech support for a few hours, they eluded to the fact that this +could+ be a hardware related problem. (driver, adapter properties, etc)

(Lync 2013) Lync Web App: Call ended because of network connectivity issues

I'm having a very strange problem with Lync Web App. When I try to join a meeting, it works in the following conditions:
- With the Lync 2013 windows client: always (internal network, external network)
- Lync Web App: Works in internal network. When I'm on an external network, I'm able to join a meeting, but when Lync Web App tries to establish the call, it ends with the error: "Call ended because of network connectivity issues".
On the other hand, IM works with Lync Web App (internal/external network). But all the other features (presentation, audio call, video call) are not working.
Did anyone experience such an issue ?
Thanks,
Antonio

Hi,
Since the issue only happen on Lync web app that was handled by reverse proxy. The issue maybe related to RP configuration. Please refer to one of the following links to check if the RP configuration are correct.

HP Dm1-1102sa Strange charging issue

Hi,
My laptop (HP dm1-1102sa) has developed a strange charging issue. The laptop will initially charge fine then it will flick between being charging and running on battery constantly. I bought another battery to see if it was that but the problem still occurred. I then took it apart to check for loose connections and voltage. There were no loose connections and the pins on the battery terminals were showing a constant 18.5v. I tried running the laptop with out the battery and the laptop shutdown after a while.
Anyone have any ideas on what I can do next?
Thanks in advance.
Simon

Hi, thanks for the response, I had a look at this page and followed the suggestions, it all came up fine.
What I have noticed is the bi-coloured LED that sits next to the power connection on the left side was white which indicates not charging (so it seems) , even when it was at 73% and plugged in it wasn't charging, I removed the battery and gently blew out the plug and socket and re-connected the battery several times to see if it was a contact issue, I also did the same for the power connector.
The odd thing was it would run perfectly on battery and on mains just not charging.
I downloaded the latest bios revision (not yet installed), so I left it for a while with the battery and the mains lead disconnected, reconnected everything and noticed the bi-coloured LED was now orange so I left it on the desk for a while not running and when I did start it up some time later it was upto 95% charge and then stopped charging again, and again the LED was back to whte.
Today after receiving this message I tried the suggestions as per the document (except I pulgged in the mains first which brought up the orange LED), performed the tests, I had already tried the HP assistant battery test in windows which showed no issues (still wasn't charging, sitting at 73%), now with it running in front of me (not the computer I am using to type this response) the LED is still orange and the message I get now is "99% available (plugged in, charging)".
So for the moment it appears to have righted its self which is a concern, I hope that it stays this way....

Strange connection problems -- software or hardware?

I've been experiencing some strange connectivity problems of late, and am wondering if it's a software or hardware issue. I'm running OS-X 10.4.11, and have noticed web-associated "drop-outs" occurring. When I'm browsing, any of the following will happen:
1. the pages will periodically stop loading, or will take forever to load a few final images.
2. the page will load with a different format (completely unformatted, like a throwback to Mosaic!).
3. the page won't load at all, and will instead give me either a "DNS error" message, or will default to my ISP's "We couldn't resolve your page" message.
4. Nothing out of the ordinary happens.
Throughout this process, the connection strength is 100%.
It seems this happens with both Firefox and Safari. Is this an issue with driver software, or is my Airport Card giving out? My computer is about 3 years old.

I have been having intermittent connection problems on several computers over many years now. We have 12 eMacs, all purchased within a few months of each other, all with 10.4.11. Some computers have almost perfect internet connection, but some are constantly losing connection. If the user just waits a few minutes, the network just comes back or if they open system preferences and renew the DHCP lease it comes back as well. We have tried replacing cables, reloading the operating system, repairing permissions, reseting safari... We are all connecting through ethernet cables through wall jacks then to a switch that is connected to our router. Our DSL provider claims it can't be wiring or a problem on their end or they would see it and we would all have problems. I am not super computer literate... Any suggestions for what I should check on the 4 or so computers that are having lots of connection problems?
Thanks for any words of wisdom!!!

Resolve a Wi-Fi connection issue when waking from sleep

Hi,
In the recent release for Mac OS X Lion 10.7.3 "Resolving a Wi-Fi connection issue when waking from sleep" was supposed to be resolved, not so at my end. Has anyone else encountered the same issue and if so will there be a resolve.
Thank you

Hello BGreg and thank you for your answer,
I have alreadty read about this solution, and tried it.
I downloaded the 1.2 Go file, and applied it. And repaired permissions.
Everything went fine.
Unfortunately, it didn't solve the problem.
Meaning that when iMac wakes up, it doen't join my WiFi network.
I have to do it manually.
I don't know what to do : it is very strange because I never had that problem with OS 10.7.2 !
And my network setup has never changed.
another info :
I noticed that in the network setup screen, when I want to close the little lock to restrain further modifications, it won't close. Weird !
Do you think I should call Apple Assistance ?

USB connectivity issues

I recently bought a 20GB 4G iPod from a friend, who had bought it originally off of ebay atleast a year ago so all I have is the ipod itself and a usb cable.
Everything on it works fine, all of the music previously put on works fine, as do pictures, etc. But when I went to go add and delete files off of the ipod I got the "USB Device Not Recognized" balloon popup in XP. After going through these forums and numerous others I haven't been able to accomplish anything. I've tried the 5R's (except for restore as I haven't been able to get the ipod connected in any way to this computer).
I have another computer downstairs which is a few years older, about 5 years old but which has XP installed aswell, so I figured I might try and see if I could get anything to work on that.I tried to plug the ipod into just to see if something would work, and it showed up in My Computer right away before I had iTunes installed. I did, however get an error about the usb ports not being high speed, I'm assuming they're USB1.1 giving the computer's age, but it worked nevertheless. I got the ipod to charge, it to be accessible from iTunes, and to show up in Windows Explorer without a hitch.
After having it fully charged I tried once again to hook the ipod up to any usb port with no avail. I checked both computers' properties and found both have 500 mA to each USB port, so I would assume the USB 2.0 ports would have a better chance of working than the 1.1?
Any help is greatly appreciated, let me know if you need more information, thanks!

This may sound really strange, but if your computer has a FireWire connection, try using that instead. I recently bought a new computer (HP w/Windows XP) and had all sorts of USB connection issues.
USB Device Not Recognized
iPod needs to be restored
Cannot Read USB Storage Device
Finally fed up, I tried the FireWire ports on the computer and it worked not problem. iTunes popped right up and started updating.
