Timemachine only connects over wired network

Hi
I have an iBook G4 running 10.5.8. Recently I purchased a NAS box (Buffalo Linkstation) with the intention of using Time Machine to back up my ibook. After a bit of fiddling around with setup everything was working fine, for about a month. Now Time Machine can no longer see the sparsebundle image on my NAS box even though I can mount the volume via AFP and Samba. As far as I know I haven't changed any configuration settings on either the NAS, the iBook or my wireless router.
I was all ready to blame the NAS and send it back, then I noticed a curious thing. If I connect my iBook to wired ethernet everything works fine again, Time Machine can see the volume, connect and backup no problems. Disconnect ethernet and turn on Airport, nothing works again. I don't think it is the quality of wi-fi connection as I have run some network quality tests and it is comparable to wired ethernet.
I am at a complete loss, does anybody have any ideas please? Any technical information on the mechanisms Time Machine uses to scan for backup volumes might also be useful?
Thanks in advance

I got Time Machine to work with the NAS volume by changing the following command line setting.
"defaults write com.apple.systempreferences TMShowUnsupportedNetworkVolumes 1"
As that command makes clear, Time Machine does not work well, if at all, with most network drives. See this Apple article: Disks that can be used with Time Machine.
Use this at your own risk: First, since it is *unsupported by Apple,* there's nowhere to go when there's trouble.
Second, you're risking a future update preventing it from working, and perhaps rendering your backups useless.
From a post in another forum (found by V.K.):
The technical reason why Apple limits Time Machine to 10.5 AFP volumes appears to be to prevent disk image corruption. There were additional features added to AFP in 10.5 to support Time Machine. These presumably allow the disk image engine to force disk image journal data to write out all the way to the disk. Without such features, a network interruption can result in a corrupted filesystem on the disk image despite journaling. Remember, journaling relies on the journal being written all the way to disk before the changes take place. If you can't guarantee that (e.g., because of network/NAS buffering) then the journal is useless. Time Machine appears to rely heavily on disk journaling to deal with network drop-outs, interrupted backups, and the like. Take this away and your data is at risk.
If the NAS you are using supports these features it should report them to the OS and you should natively be able to choose that volume. If you have to trick the OS to use the volume it means the NAS does not support it.
Since you had to use that command to get it to work, most likely you will not be able to do a full system restore from those backups.
To summarize: if you care about your backup data you should avoid using non-natively supported AFP servers.
That post obviously applies to Leopard; Snow Leopard appears to have added some requirements, that are also not supported by many NAS devices: some that were working with Leopard no longer work with Snow Leopard.
Since you had to use that command to get it to work, most likely you will not be able to do a full system restore from those backups (per #14 of the Frequently Asked Questions *User Tip,* also at the top of this forum).

I have a Time Capsule as my router. I can connect wirelessly to the network and internet with my MBPr, but my Mac Mini will only connect to the network wired or wirelessly. Airport on it sees the internet as green, but will not connect.

I have the Time Capsule hooked to a wireless modem. It uses a static IP, which is put in and running. The MBPr connects, as well as my iPhone 5, to the internet and network without problem. I can see the Mac Mini, external drive attached to it, and the Time Capsule. The Mac Mini connects to the network wired or wirelessly, but not to the internet. On wireless, using AirPort the Internet shows green, but no connection when I open Safari. The settings under network settings are identical except for LAN IP between the Mac Mini and the MBPr. I was hoping someone might have an idea of what was going on. Before I moved the Time Capsule was on Bridge mode from another router, now it is on DHCP and NAT for the internal network.

No, its is connected direct to the providers fiber box.

Make TC invisible over wired network.

Is there a way to hide the time capsule over the wired network? Other Macs in the building can see and choose my TC as a TM backup location, its password protected so they can't, but I want to hide my TM completely. I have already created a closed wireless network so nobody can see it but its broadcasting its name over the wired to all other macs. Thanks for your help.

Yes, but it is complicated.

For most people disk password or user profiles would be enough.. plainly they can choose the TC for TM but without actual passwords they can never accomplish that task. I am not sure what you gain by completely hiding it.. ??
Same as closed wireless network btw.. anybody who knows about wireless is not going to be tricked by hidden ssid. It is the password which protects you.. not the hidden ssid.
Anyhow.. tell me how you get internet?
And how is the TC connected to the network?
Does it have to be connected for other clients you own to get access to the internet? ie if you are the only person using it.. can we establish a private network to the TC.. would that bother you?
We can only partly hide it in the main network.. in that again, just like a hidden ssid.. anyone who knows about networking can find it.. Isolated from the network nobody can access it at all.

HP CP1525nw - Connect via wired network and wireless ad hoc?

At my job we have our HP 1525nw printer connected into the network printserver via ethernet cable. The printer has its own IP address setup on the network.
With support for XP computers ceasing, a copule of computers will be cut off/blocked from the job's network. One computer is close enough where we can make a USB connection to print. Another is located on another bench. Furthermore, the one that is further away from the printer also can't be upgraded to a compliant Windows OS due to incompatibility with specialized software used to operate equipment hooked up to this computer.
Is it at all possible for this wired network printer to also be setup to print wireless via an ad hoc connection? The idea was perhaps we could install a wireless card on thix XP computer and print wirelessly via a direct connection to the printer, avoiding having to connect to it via the wired network at all. But it is sounding like this wouldn't be possible. Looking for a direct answer before I start shopping around for a wireless PCI card.
This question was solved.
View Solution.

From other posts I have read, I think the CP1525 can be either ethernet or wireless not both at the same time. That will prevent you from setting up with an adhoc network the way you described.
You might try an inexpensive wireless router with a build in print server attached to the usb port. then add wireless USB wireless dongles to the XP computers. Be sure you make sure that the wireless dongles support XP. Also for security purposes you will want to leave the wireless router disconnected from your network.
If your fairly tecky and you don't mind playing a bit you could check your local thrift store for a used router with a print server. For printing you don't need the fastest wireless available. Just make sure it is a b/g router (not a B only one).

PEAP encryption over wired network?

I have Wicd in LXDE and loving it, but the problem is there isn't wireless availability in my room. So I'm trying to find a way to connect to PEAP over wired, an issue which the Wicd people say they've never run into.
The example configs and everything else seems to be geared toward wireless, but there's almost nothing I can find for encryption over wired, and frankly I can't do EVERYTHING in the building lobby.
----------FIXED----------
I had Arch before and liked it just dandy, but switched for a little while to Ubuntu. Now I'd like to try it again, but I've got a problem: I'm on a University network and both the hardwire and the wireless are encrypted. The wireless is WPA enterprise and the wired is 802.1x, both are PEAP Version 0 with MSCHAPv2.
I had absolutely no problem getting Arch setup back home when I could use the ethernet cable and get everything downloaded/installed, then I'd throw Wicd into the mix and bingo bango I'm set up. Problem is all my googling and searching has given me no indication of how to proceed with installation if my network requires authentication. It's proving a bit of a roadblock.
-------END OLD PROBLEM---------

We have a simmilar setup at our dorms, and my config looks like this for wpa_supplicant
network={
key_mgmt=IEEE8021X
eap=PEAP
phase1="peaplabel=0"
phase2="auth=MSCHAPV2"
ca_cert="/path/to/root.crt"
identity="" #your username
password="" #your password
Use the wired driver, and it should work.

IPhone 6 prioritizes poor 4G Connection over strong network extender 3G signal

I use the network extender due to poor coverage in my basement. I have spent multiple hours with both Verizon and Apple trying to figure out why sometimes my iPhone 6 won't connect to it, including a hard reset of the iPhone. I finally figure out that the iPhone 6 prioritizes getting a 4g connection, not matter how poor, over a 3g connection, no matter how strong. As a result, my phone will occasionally latch on to a weak 4g signal and not connect to the Network Extender. When I then get or make a call, the connection and voice quality is terrible. The only work around is to completely turn off LTE. This forces connection to the 3G Network Extender. Of course, I then forget to turn it back on when I leave the house. Are there any plans to provide some sort of a fix or a setting to make this more convenient?

PROBLEM SOLVED (so far). My wifes iphone 6 plus had the exact same issue. . .would keep going back to the weak 4G signal over the network extender.
To fix it, go into SETTINGS>CELLULAR>Enable LTE and set to DATA ONLY. . .NOT Voice and Data.
So far so good. . .only affects being able to make calls and surf the web at the same time, so if you don't do that much then you're not going to be inconvenienced too badly.
Hope it works for you! Also, if the iPhone 6plus is like my Note3, then it has 2 antennas, 1 that's hooked into 4G and the other one that's connected to the network extender. . .it defaults to the 4G signal, so it may only show minimal bars till you actual make or receive a phone call then it'll jump to the network extender signal strength.
Good luck!

Not Connecting to Wired Network and Forcing the loss of all Connections on the Home Network

Just got a new G550 laptop w/Win 7 OS. Tried to connect to wired router and got message "network cable not connected". Recycled laptop and router and came up with router connected to the laptop. Same message after search and identify steps finished. I then noticed I lost connection to the net/router with my other home networked units as well! Tried another cable, same results along with losing the entire home network connection. Disconnected the G550 from home network, via the cable, and the home network reconnected without any intervention. Tried another reboot directly connected to the cable modem, no go there either!
I also rebooted with the wireless search shutoff and got the same problems as on the wired attempt. Thought it might have been the NIC card so I exchanged the system back at the store. Sorry, same problem!!

I have a very similar problem... New Lenovo G550, running Vista Home Premium 64-bit. Right from the start it causes my TrendNet TEW-432BRP router to crash every 10 seconds. I bought a new DLink WBR-1310 and experience the same problem. Connecting to either router through either a wireless connection or a LAN cable connection causes the router to crash every 10 seconds. The router crashes, reboots, establishes a connection with the laptop, communication starts and then the router crashes again.
I am looking for help.

4400 Controllers - Best Practise for connecting to wired network

At one time the best practise recommendation for wireless was to treat the traffic as untrusted and separate it from the wired network by firewalls and intrusion detection. A lot of the reason for this was the weakness of WEP. Now with strong authentication and encryption (e.g., WPA2 and EAP-TLS) in use, and the use of wireless controllers, I'm wondering what the industry is recommending (and doing in case the actions aren't the same as the recommendations).
Are organizations connecting the wireless controllers directly to the internal network or are they separating them with a firewall and IDS infrastructure? If the latter, what does the architecture look like? Are there documents on the Cisco site or on the Internet that show how the controllers could be firewalled? Everthing I've seen shows connections directly to the internal network. Is firewalling the controller an overreaction to the historical paranoia from the WEP days?

The argument would be that regardless of what security you put on the wireless, you still don't have the physical security - i.e. someone doesn't need to walk into your building to use your network.
Beyond that if you're using strong auth/enc you can currently be considered safe, we have customers using that direct into their LANs (but then, we also have customers with WEP direct into their LANs!)...
If you are concerned or really need belt 'n' braces security, then go down the firewall/IDS route - there's no harm in it if you have the money. It really depends how much functionality and ease of use you need to balance against it.

Wireless losing connection to wired network and lan

I have a customer that has an 871W ISR. They are using WEP encryption and a mix of b and g cards. Recently they have started losing connection to all of their wired network resources and the wan, but they don't lose association with the 871W itself. They show excellent signal strangth and keep their IPs. A reboot of the router immediately fixes the problem. There seems to be no pattern or common event that triggers any of this. Anyone else seen this problem before? It started happening after I did a sh tech and the router locked up halfway through it, so I had to reboot. I've reloaded the image thinking that may fix the problem and it has not.

You can clear the interface statistics on the Detailed Status tab, and let traffic run for a time, then refresh the statistics. The ratio of errors to good packets sent and received should be better than it was prior to the test.

DMM - DMP connectivity over DSL network

Dear All,
I would like to know whether it is possible to connect DMM - DMP over DSL Network.
- I have DMM with private IP 192.168.1.100 have static net public IP 58.177.200.xx
- I have DMP with private IP 192.168.xx.xx connect under ADSL network with Dynamic IP address.
I check NAT enable on DMPDM but It ask me to enter ADSL public IP. When DSL line down and reconnect IP is change.
What Should I do?
Thank you very much
Sukitti

Hi Sukitti,
I'm afraid this will never work. As you already saw, you can use the DMP with NAT, but the public IP needs to be fixed.
Your best approach would be to contact your ADSL service provider and request a fixed IP for that connection. Most of providers give this option for a small extra amount

Connecting to Airport Express speakers over wired network

I have my speakers plugged into my Airport Express and obviously computers connected to it via WiFi are able to stream music to the speakers through iTunes.
I am at university and there are many users on the network, and my Airport is setup to simply act as an access point. Is there any way users on the network (NOT the wireless itself) can connect to my speakers through iTunes?
So far I have tried turning on sharing the speakers and telling other computers to look for them but have had no luck. My computer is able to connect to them but only when connected to the wireless.

Many thanks for your replies.
I do in fact have my Airport set to Bridge Mode, but this unfortunately does not seem to make any difference. Other users' iTunes still cannot see the AirTunes speakers.
I was reading this guide - http://forums.whirlpool.net.au/forum-replies-archive.cfm/228336.html - and it seems the poster, Daniel, had managed to get other devices on the network (wired, not wireless) to stream music to the Airtunes speakers, so perhaps it is possible but there is something I am doing wrong. Any ideas?

Printer Sharing works over wired network not over Airport - Why is this ?

Computer A (eMac, 10.2.8) has HP Laserjet connected via USB. Settings : Printer Sharing On, Firewall Off.
Computer B (G4 iBook, OS 10.3.9) when connected via ethernet cable (via router which shares my DSL line) can see and print the HP Laserjet.
Computer B when Airport turned on to join network via AX (plugged into router) cannot see any shared printers. Nor can I add Rendezvous, Appletalk or other printers.
I only just added Airport capability to the iBook, other network features (internet access, file-sharing with eMac etc) all seem to work fine.
If I plug the Ethernet cable in, computer B can now see the shared printer. If I then unplug the Ethernet cable, reverting the computer B to Airport access only, I can see and print to the shared printer.
Clearly, therefore I can print over Airport to the shared printer, but the mechanism of plugging in and then unplugging the ethernet cable isn't exactly an advert for Apple simplicity and elegance.
Would anyone care to enlighten me as to what is going on and how to fix it properly ?
Kind Regards

Greg,
many thanks for the prompt reply, and this looks a good suggestion. To clarify; I have a wired router (Netgear, can't remember exact model) and 2 Airport Express (which I call AX-A and AX-B). I use AX-A as a wireless access point and it is wired into the Netgear router. AX-B is used to provide internet access to an older iMac in a remote part of the house (not that my house is very big or anything, and is not (I believe) relevant to my printer sharing issue.
I am now using AX-A to allow my iBook to join the network. I will check when I return home, but believe the AX is already set up not to distribute IP addresses - these are from the (wired) router.
Cheers

IPod Touch only connects to home network; not Airport, Starbucks, Panera...

Before I start, I've read the FAQs and have looked through a number of topics already posted.
I seem to have the opposite problem everyone else is having. My iPod Touch connects just fine to my home wireless... It connects and I'm able to browse the internet, download apps, etc without fail.
However, when I was at the airport recently (both St. Louis and Dallas/Ft. Worth), my Touch would "connect" to the wireless there, but I couldn't go on the 'net or get new apps, etc. It was behaving as if I wasn't at a location with wireless access. When I returned home, I went to Starbucks, Panera, McDonald's... several places with free, open, easy-to-connect WiFi (and took my laptop to make sure that their wireless was working), and had the same problems as I did at the airport.
Considering the best part of having wireless on the Touch is that you should be able to access it anywhere with WiFi, it seems kind of "useless" to have it only work at home (I have two computers at home; so it's not like I need to use the Touch for internet there).
Any thoughts? Obviously, the whole "check your router settings" / "reset your router" answers are not going to help me, as I have no control over those, nor can I see them at these places. Help would be greatly appreciated!

I'm having the same problem. My iPod Touch connects to my home network and another secure network for which I enter the network name and password. However I am unable to connect to any free WiFi, even when my laptop can access it with no problem. The signal is apparently strong; I can see all the bars on the upper left, but when trying to connect to Safari or the app store it says that there is no connection.
