10.5.2 Leopard unable to connect to LEAP network

We have a wireless b/g network at the office that authenticates with LEAP. Whenever we use Leopard, including 10.5.2, we are unable to authenticate to the network. Most commonly we get 'Connection Timeout' as the message received. This is extremely frustrating, as one user with 10.4.11 has no problems at all (MBP 2.2Ghz) but the others, all under Leopard, are unable to connect. (Interestingly, there is one router on our network that the Leopard users can connect to, but it won't work with the others.) Again, Tiger users, no problem at all. Has anyone experienced this?

Sadly, no. And you're the first response I've received. I can't locate anything online either.
As far as MySQL is concerned, it works fine if you start it from the command line. You can change the the mysql/bin directory and type ./mysqld_safe [RETURN] and it will start the service. Then in another window execute your commands.
Which leads me to believe it's an issue with the Preferences Pane.
Good luck - and let me know if you find a solution!

Why can I connect to my home network with my iPhone 5 in one room, but when I move to another it is 'unable to connect to the network'

At home, I can connect my iPhone 5 to my home wifi network with no problems, as long as I stay downstairs.
As soon as I go upstairs my phone disconnects from the network. I can still see the home network it in the available network lists (with full signal strength), but when I try to reconnect I get an 'unable to connect to the network message'
If I move back downstairs it reconnects
This has only started happening in the past week or so
I've tried to forget and rejoin the network, but this doesn't work
I reset my network settings on the phone. This worked for a couple of hours and I could connect to the wifi upstairs, but now it won't connect again.
Does anyone have any ideas what is causing this?

Sounds like your wi-fi signal strength has degraded. Try rebooting your wi-fi router, or get it serviced.
Do you have similar issues with any other wi-fi routers?

Do other devices work with this WiFi system?

EthernetIP, Unable to connect to the network path specified, Multiple NICs

I have not been able to find an answer concerning this error, so I am hoping someone can help.
Computer has LabVIEW 2013 with the NI-Industrial Communications for EtherNet/IP 1.2.1 addon with Win XP although I have verified the same setup with Win 7 x32 with the same results. I am using the EthernetIP CIP Get Attribute Single.vi and the corresponding "Set" vi.
I am using a pc with five network cards, one for the corporate network (dhcp) and four that are connected to four Rockwell PowerFlex 700S AC variable drives via CAT6 crossover cables. Each 700S drive controls a motor in an engine dyno teststand. The 700S drives have the latest available firmware installed. The four NIC/700S pairs have hard coded IP addresses with the appropriate subnet masks for proper routing. I can use the Windows "ping" command without errors. The program uses a QSM-PC architecture which I have four separate qsm loops that "talk" to the each drive, those loops constantly request three parameters from the drive, a boolean drive status array, the rpm , and the torque every 250ms using the CIP "Get" vi. That data is then sent to the main front panel via shared variables. When the operator wants to say change the rpm, a write command is inserted into the queue, and the CIP "Set" vi is used.
My problem is when I start the program, it is hit or miss on whether these loops will begin to loop through their states. If they start, the program is rock solid. When one of the loops does not start, which is most of the time, the error returned is the "-251723767 Unable to connect to the network path specified". See the attached pictures. So if I disable three of the four loops, the error never shows up. Adding another loop or more will cause the error. Slowing down the request rate does not fix the issue and it is not always the same loop that will throw the error. Each qsm loop has its own session name and its own action engine with the only common thing amongst the action engines would be the "Get" and "Set" EthernetIP VIs.
No more ideas.....Kevin

250 ms is a pretty slow update rate for CIP so Why use a nic for each drive? Use 1 drive nic in your PC and use a network switch to connect with your drives. If You have more then 1 nic you need to specify the nic to use for each loop for each drive IP address so the drive and the loops are using the correct IP settings. You should be able to use as low as 30 ms updates with no problems.

Unable to connect Wi-Fi network after ISO 6 update

unable to connect Wi-Fi network after ISO 6 update. I'm not impressed.

I updated to ISO 6 on my Daughters Iphone 4S, my Iphone 4, and I have now received my new Iphone 5 yesterday and now all 3 of them have wi-fi issues. I know its not my wi-fi because My Daughters Ipad 2 and my Wife's Iphone 4 is still on 5.11 and the wi-fi works fine. I cant understand why apple have not been saying what's going on and when they will fix it. I have tried everyone's suggestions on this forum and the Internet. Still no luck.

Same To me. I have Asus WL-500W router at home, WPA2-PSK(AES), password similar to this "lIGf@91pY0TnFY!Jh@7LjTUlsL3ZPY", MAC address filtering. My old Nokia E51 works, my Touch Pro Works with it. When i try my one day old Nokia E72 it does not work, the same like others:WLAN: Unable to connect. Wlan Network not Found. E72 works at my work wifi, which has the same settings but without mac filtering. Have no idea what is happening, all is setting correctly. MAC address of E72 is allowed on router. It has the same settings like E51, but E51 works like a charm E72 does not work. What is wrong?
As already suggested, you could try disabling the MAC filtering from the router, just to outrule possibility of a typo while entering E72's MAC address to router settings.
Have you tried swithing a WLAN channel that your router uses?
Log in to your router's web management pages (check router's default IP address and username/password from it's manual) and switch of the "Automatic" channel selection mode. Try few different channels, like 1, 3, 6, 9, 11, if one of the channels happens to work any better. Note that in case you have set your router to use channels 12 or 13 (or in case "Automatic" channel selection mode has decided to select channel 12 or 13) you must have a SIM card inserted and some other than "Offline" profile enabled on your phone since Offline mode (i.e. airplane / flight mode) won't allow your phone to operate on higher channels than 11.
In case you have configured your WLAN network (SSID) to be "hidden", try disabling hidden SSID mode on the router.
Asus WL-500W router seems to be a pre-standard 802.11n device so might be worth looking in to your router's WLAN settings and see if playing around with router's WLAN operating mode and settings improve the situation. First of all ensure that your router is not set to operate in 20/40MHz mode (set it to 20MHz only) assuming that the router is in default 802.11b/g/n mode. You could also try disabling the 802.11n mode completely by selecting a 802.11b/g mode (if available).
You should probably also check that you're running latest (2.0.0.6 ??) firmware version on your Asus WL-500W router since there seems to plenty of complaints regarding WLAN connectivity and stability issues (in general, not specific to Nokia handsets) with this particular router model.

IPod Touch unable to connect to wireless network.

I just got an iPod Touch 4 for my birthday (w00t), however I cannot seem to get it to connect to my wireless router. Everytime I try, it says Unable to connect to network. I reset the routers password, but it didn't do anything. I saw in other threads people said to switch ti WPA security, but mine is already set as WPA Personal. I'm not sure what to do! Please help!

NO I did not and thank you very much for the advice. My problem was stated incorrectly in that while I am able to connect to the wireless from that point on I am unable to connect to the internet. I will check the article referred to.

Suddenly unable to connect to wireless network...exhausted all fixes

I’ve got an odd problem with my two-week old MacBook Pro and its connection to my wireless network. I’ve done what I think is pretty exhaustive troubleshooting, but remain baffled. Here’s the story.
This morning I connected to my wireless network (DSL 2WIRE modem/router) with no problem. This afternoon I returned and Airport refused to connect, giving me the error message, “Airport is unable to connect to the wireless network…” The network shows up as being available, but when I attempt to connect, it wont. (I didn’t make any changes or install any programs this morning).
Here’s what I’ve done:
[1] Restarted the router
[2] Repaired permissions
[3] Deleted the network’s entry in Keychain Access
[4] Re-entered my WEP code (assuring it is in correctly; I’ve tried both with the “$” and without)
[5] Used interface robustness and without.
[6] Attempted to join the network from the System Preferences>Network.Airport route.
[7] Created a new account and tried connecting.
Other tidbits of information:
[1] Another MacBook in the house connects to the network with no problem.
[2] My MacBook can connect to another (unsecured) network that I can “see” in my house.
So, it would seem my Airport card is working okay.
Any ideas??

Some more info (in case anyone is listening...)
I tried turning off the WEP code and could connect. (Since I share files on my home network, this isn't a "solution").
I also tried Resetting the MacBook Pro System Management Controller (SMC)(See: http://docs.info.apple.com/article.html?artnum=303319). I did this (I think -- there wasn't any indication that the reset "took"), but alas -- no luck.
I gave Apple Care a call, but the support guy, while courteous and all, didn't have anything to offer other than telling me to take it in to an Apple Store for a repair (clearly it isn't a hardware issue).
Heeellllppppp!

MacBook (10.4.11) is unable to connect to wifi networks

After updating with 10.4.11 (and the associated 2008-01 Airport update) a few months ago, my Intel MacBook has been unable to connect to my WPA2 network.
It will see my network name in the Airport drop-down menu, but fail to actually connect. The icon appears as if the notebook is rapidly connecting and disconnecting -- switching from five bars of signal to none and back again every few seconds. During this time, my MacBook never reports getting a connection, and all other devices on the network experience severe interference. I am able to connect to most, but not all, unsecured networks.
System Profiler reports my wireless card as AirPort Extreme (0x168C, 0x86), Firmware Version: 1.3.5 .
My router is a D-Link DGL-4300 with the most recent firmware. I am running an 802.11g network at 2.437ghz.
I've tried the following already, unfortunately without success:
. Switching to WPA from WPA2
. Removing all the preferred networks from my System Preferences and adding them back in again.
. Removing all the network info in my keychain and reconnecting to the network from scratch
. Switching the router to channel 11 (away from 6)
. Turning Interference Robustness on and off
. Manually specifying IP and DNS in my network settings, rather than DHCP
. Removing all other wireless devices from the network
Looking elsewhere on the net I find that a few other people seem to have this problem, and so far the only solutions I've seen are "roll back to 10.4.9" and "disable security on your home network," both of which are obviously untenable for security reasons.
The one (and only) WPA-secured router I am able to connect to is the Airport at my local Genius Bar, so they're unable to help me.
Has anyone else seen this, or have any ideas?
Thanks.

Well, I downloaded Pacifist and the 10.4.11 Combo Update. Pacifist verified the AppleAirPort and AppleAirPort2 .kexts on my drive as matching the ones in the package, but I forcibly reinstalled them anyway and rebooted. Still no luck -- now the network is back to the four-bars-no-bars death loop without even popping up the error dialog.
Luckily however Pacifist turned out to be the solution to the problem. A Google search on "Apple broke Airport" eventually led me to this thread with detailed instructions on rolling back to the previous version of the Airport driver, before the 2008-01 update: http://www.tuaw.com/2008/03/28/airport-extreme-update-2008-001-for-tiger/#c11509 504
I'll paraphrase it here for anyone else who has this problem:
Download the Airport Extreme client software version 2007-004
from http://tinyurl.com/yw3dnu.
Download and install Pacifist from www.charlessoft.com.
Delete /system/library/extensions/io80211family.kext
In Pacifist, open AirportExtremeUpdate2007004.dmg
and expand the sub folders until you can see the io80211family.kext
extract and direct it to extract the file to the
/system/library/extensions/ folder
restart
So now my Airport works again, though without whatever security they put in with 2008-01, I guess.
I suppose I'll have to embargo future OS updates until this gets straightened out, or else re-rollback the io80211family.kext after each one. I sure would like to talk to whoever wrote this update at Apple!
Thanks for your time, BD.

Unable to connect to wifi network

I put my (2 day old) iPT to sleep last night in the middle of watching some Netflix streaming video. When I woke it up this morning, the Netflix app tried to resume play and failed. The iPT started asking for a network password. I made a few careful attempts to enter it (it is one of those 64 random character things, and my iPT typing skills are nascent) and it failed to connect. Finally iPT began saying 'unable to connect' and stopped asking for a password. I checked the router, connected with my laptop, no problems there. Perhaps the router has some lockout after failed login attempts, but if so I could not discover the setting in order to reset it.
Finally, I reset the iPT network settings, and was able to connect and enter the password successfully.
My question is this: why did this happen, and can I be at all confident it won't happen again?
I've never had a similar problem with other wifi devices I've used with this router since setting it up over a year ago, so to my mind it is obvious there is a problem with the iPT wifi hardware or software. Needless to say, it is a pain to enter the wifi key once, let alone every few days.

Your post indicates that you are using WEP security. Do as Apple suggests and move to WPA or WPA2 security. WEP is obsolete and can be cracked in seconds with widely available software.

"Unable to connect to hidden network" - Losing wireless connection on 1 PC in network - EA4500

We have a two-month old EA4500 router. Over the last couple of days one of our wireless pc's (running Windows 7) has occasionally been losing connection to our wireless network. Troubleshooting indicates that it is "unable to connect to the hidden network (our network name)" Our network should not be hidden, and our 2 other wireless devices are not experiencing this issue. When the disconnect occurs, the only way we are able to reconnect the PC is to disable and reenable the wireless adapter through device manager, or pull the adapter out of the USB and re-insert it. (The USB wireless adapter is also new - only a month old and is also a Linksys ). Does anyone have an idea what could be causing this issue, and what we can try to fix it? It's getting very annoying. Thanks!

There are times that these USB adapters (especially those Wireless Network Adapters) requires more power and they can't draw enough power once plugged in to a USB hub or USB extension cables. Can you try to plug it in directly to a USB port at the back of your computer? So that the adapter would draw enough power from the motherboard.
If everyone needs to believe in something, I believe I'll have another beer..

Unable to connect to wireless network

I am unable to connect to my wireless network with my MacBook.
I have no trouble connecting with my windows PC. I have double checked the WEP key and checked that I am using the correct key type (128 bit hex). There is no MAC address access control on the network and DHCP is available.
All I get is a message saying 'There was an error joining the AirPort network "network-name"' and two buttons: 'Try again' (which produces the same error) and 'OK'.
Can anyone help?
MacBook Pro 15" 2.16GHz Mac OS X (10.4.9)

Hi,
I'm also having this problem of not being able to connect to a wireless network. However, I'm in Spain and have my MacBook. I was able to connect to the wireless network with no problem for about 5 days' and then access stopped. I get the same password edit saying the network does not recognise the pw. I've tried all the proposed solutions described in this thread: entering the data manually, using a $ or " sign and to no avail.
The airport symbol is grayed out. However, when I open internet connection to join the network, 15 other networks including my own show up, so I believe the airport card is working okay. (everyone seems to have WiFi in the area).
Does anyone know if there is something peculiar to Europe I need to do in order to gain wireless access again ? I know the broadcast chanels are 1-13 vs 1-11 in the US. But I don't think this is a problem since I had access for a time.
Any info welcome. Sorry if I'm threadjacking here but I don't see where to start a new topic. The network is fine as I'm connecting using an ethernet cable.
Thanks in advance,
J.

WiFi - unable to connect to home network

I had a problem syncing and iTunes not recognizing my iPod touch, (and my new iPad). Did a restore on the iPod Touch and that solved the syncing problem, now I cannot connect to the WiFi in my home, (cannot connect with my new iPad either). I have a Linksys Wireless-N Broadband Router Model WRT160N. I am dying to connect the new iPad and get it up and running, etc. Can anyone help me solve the "Unable to connect to (my home network's name)".

Use G band, not N. I encountered a lot of problems with my new router on wireless N. Here is a reply I wrote for the other posts about iPad connectivity problems:
I have the base iPad 16gb Wi-Fi model and it was connecting to wifi fine. A few days ago I had to get a new modem/router. I bought a netgear dual band model (G and N) and used wireless "N" on my my two MacBooks and my iPad.
Two days ago I started getting the "Safari could not open the page because the server stopped responding." error on the iPad along with the schizophrenic signal strength bars going from three, to one, to two, to disappearing totally, to whatever, and Safari not opening pages and sometimes crashing, and when it would connect running slower than molasses.
My laptops worked fine, seeing both G and N and working equally well regardless of which I chose.
I did all the jumping thru hoops I have read on this and various forums and that Apple suggested back in April with naming each band on the router differently but with same security settings, renewing lease on Safari, reseting iPad, resetting network settings, turning auto connect off, etc., etc., etc, none of it worked.
So I started to wonder . . . does the iPad even work with "N" . . . the Apple site says "yes", but I wondered . . . what happens if I have the iPad ignore "N" and connect only with "G".
Guess what . . . that fixed the problem.
I went into Settings > WiFi > and told it to "Forget this Network" for the "N" band and then selected the "G" band.
Problems gone.
If you're experiencing the connection problems I'd bet dollars to doughnuts you're trying to use wireless "N". Have it ignore that band and use "G".

Additional things to try.
Try this first. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html

Airport Card on MacBook Pro unable to connect to VPN networks

For the last year or so (apart from two glorious months at the start of this year) when using an Airport connection, I'm unable to access any VPN networks. I always get an error saying that the VPN server is not responding.
However, if I use an ethernet connection, a USB Wifi modem or an iPhone tethering I can connect without any issues.
The VPN connections started working in January to my utter surprise. I think it may have been connected to the 10.6.6 update, but stopped working again when I did my last update on March 13th. I installed Java 10.6 update 4, iTunes 10.2.1 and Safari 5.0.4.
I'm about to install Mac OS X 10.6.7 to see if it has any effects but I wanted to know if this is a known issue and whether or not there are any solutions to the problem?
Message was edited by: Tinna
Seems like the 10.6.7 update solved the problem.

Hello Oliver,
I would start with removing your Wi-Fi network from your Preferred Network list. To do that, navigate to the Symptom: After restarting or waking from sleep, my computer might not connect to the Internet section in the first article and it will walk you through that. Another thing you can try is creating a new Network Location to see if there is an issue with your current configuration and the steps for that are in the second article.
