Connects to one wifi but not another

I've got a iMac that is connecting to my password protected wifi but my MacBook will not. The MacBook will however connect to an unprotected wifi in the neighborhood. It does that automatically. This seems to be a recent issue.

Hi foundsheep,
What is the MacBook doing? Is it getting an IP address, is it getting a self-assigned IP address? What sort of security setting is on the router?

Airport connecting to one computer but not another

Just set up my AirPort Extreme. It worked immediately on my Mac. When I went to set it up on another Mac the AirPort Extreme Utility could not find the base station when it scans and when I go to join the network using the AirPort icon on the top bar it allows me to click on the station but after I enter the password the OK button does not highlight itself so that I can click on it.
Please help.

I used the Airport Utility to enable file sharing for each of my 3 Macs before connecting them. I don't know if this is necessary but I didn't have any problem
Go to Airport Utility - Disks - File Sharing (click file sharing and enter credentials for each computer l, select read and write access)

Implicit read with assembly module instance working on one computer, but not another

Hi,
I'm trying to set up an on-site computer to run a VI which uses assembly instances for data communication, but for some reason I'm unable to establish a connection to the PLC.
I'm running the example vi "CreateAssemblyInstance.vi" to try and get the communication set up before I start using my actual program.
When I run this code on my development machine, I'm able to establish a connection to the PLC and read data. I then go into RSLogix 5000 and change the IP address to the on-site machine and try to run the test VI there, but I'm unable to make a connection. LabVIEW-side, the program thinks that it's established a connection and is reading/writing data, but PLC-side I'm getting a "Connection Failed" message in RSLogix.
I find it weird that LabVIEW thinks the connection was established just fine, which the RSLogix says it can't connect to the VI.
Just wondering if anyone else has had this happen. We aren't sure why the same VI runs on one machine but not another. We used RSLogix to change the IP address of the target machine, so we don't think that's the issue. And both computers are on the same network, so we don't think it's a firewall issue either.
LabVIEW-side, things should be identical. I'm running the same example VI that came with the Ethernet/IP module. PLC-side, we're changing the target IP of the module within RSLogix 5000 (and we're sending the updated information to the PLC) to match the machine we're trying to make a connection with. Are we missing any steps? This is the first time we've tried using an assembly module, so we're having a hard time troubleshooting.
Any ideas on why this is happening?

I'm pretty sure we're using a generic ethernet module:
I can communicate explicitly with the problem computer, it's able to use 'Tag Read' and 'Tag Write' to communicate with the PLC.
We started having another problem just recently too. The Tag Read and Write commands are almost always timing out. I keep getting the error message -251723752:
Detailed error info: Error -251723752 occurred at EthernetIP Tag Read REAL.vi;Details: The request response was not received in the requested timeout period Possible reason(s): Ethernet/IP Industrial Protocol: (Hex 0xF0FF0018) The request response was not received in the requested timeout period
I can't figure out what's causing this all of a sudden, could these issues be related?

After installing Mountain Lion, why is there Yahoo access for one user but not another?--both are administrators.

After installing Mountain Lion, why is there Yahoo access for one user but not another?--both are administrators.

We've had several instances where we have had to run chkdsk on arrays with over 1m files. Average completion time is approximately 72 hours. The maximum downtime window they have available is the 64 hour weekend window. File sizes and number of files were
much smaller then than they are now.
The idea, in theory, was to use VHDs to compartmentalize the data into smaller volumes which could be more easily managed. It would also improve performance when transferring these compartments of data as they would use sequential read/write rather than
fragmented/random. This idea was never fleshed out in entirety, they don't split data up into little containers, but simply into big ones per project. Hence the 11m files in one container that I am currently trying to diagnose.
Some other important facts: The VHD in question is mounted in B:/project/ as this server also allows remote workers to log in, but they are restricted to see only data in E:. Disks A-D are hidden via group policy.
Update: icacls is failing on a large number of files within this dataset. I counted the path characters to ensure it wasn't the 255 character limit I was encountering and verified that the paths being blocked are only about 150 characters long. Once it finishes,
I'll have to try taking ownership and then re-running it. At this point I still have no idea how long to expect. I'm running out of time as the environment will be in use again at 9AM tomorrow morning.

Bubble Event firing in one company but not another

Having spent the past 2 days trying to get the installer working (which it finally does thanks to people on this forum!), I've finally pushed my add-in out to people this morning.
Unfortunately, the bubbleevent seems to be being ignored in all companies bar the test company.
The code is below. The nominal codes do not begin with "720", so that section is not being fired in either company.
So, my question is, why would a bubble event work in one company but not another?

Hi Daniel,
Then the only option I see is that the If statement is true in one database, and false on the others.
If oApp.Company.DatabaseName = "FOLLIS_LIVE" Or oApp.Company.DatabaseName = "FOLLUK_TEST" Then
If oCheck.Value = "" And Left(oCheck2.Value, 3) = "720" Then
oApp.MessageBox("Please enter a Car Registration on row " & oRowCount)
BubbleEvent = False
Exit For
End If
End If
If oCheck.Value = "" Then
oApp.MessageBox("Please enter a Project on row " & oRowCount)
BubbleEvent = False
End If
One of this is should be different on the companies.
Nothing else comes to my mind.

It's probably because of the way the html that's calling the applet is coded, in conjunction with the vendor (Sun or MS) and version of the Plugin/JRE. This will help you ger started with diagnosis:

Our IPod connects to the WIFi, but not to the internet.

Our IPod connects to the WIFI, but not to the internet. We have a wireless router which we connect our MACBOOK to the internet and our IPod. The MACBOOK works fine, but not the IPod. It shows to be connected to WIFI, but whenever we try to connect to an internet site i.e. Sarfari, we get an message "Safari cannot open the page becuase it is not connected to the internet". We have tried rebooting, but it has not helped.

Try:
- Resetting the iPod. Nothing will be lost.
Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears
- Power off and then back on the router
- Reset network settings: Settings>General>Reset>Reset Network Setting

TS3972 My Apple TV connects to the wifi but not to the internet.

My Apple TV connects to the wifi but not to the internet. Currently using a D-Link Router and Shaw Cable in BC Canada.
Apple says "Connections through proxy servers are not supported". Would that be Shaw? How can I update the ATV
software without connecting to a TV and the internet? Can I connect it to my MacBook Pro? ATV worked very well in Arizona
using CenturyLink as an ISP provider and their modem/router. ATV software is 5.0.

What happens when you try to connect? I would contact your ISP

Problem with SMTP from one computer but not another

I have an iMac connected directly to my network via Ethernet and a MacBook Pro which connects via wireless. I have a program installed on my iMac that sends me alerts via e-mail, and it works just fine. When I try and use Mail, however, on my MBP with the exact same settings and credentials, it fails. To make this even more perplexing, Mail works fine from my office on a different network.
To work around this, I use Comcast's SMTP server on my laptop, but why would my regular e-mail provider's SMTP work on one machine and not another on the same network? The only difference is one is connected via Ethernet and the other by wireless.
I use a Time Capsule as my router and wireless access point. Has anyone got an idea about what's causing this?

Please report the relationship, if any, of the "regular e-mail provider's SMTP" and your ISP? If Comcast is your ISP, they regularly block use of Port 25, but if you have selected Use Default Port in Mail Preferences/Accounts/Account Information for the Outgoing Server, then it may be making the wrong choice to work with Comcast. Regardless of the ISP, for this regular account click on the arrows beside the name of the SMTP, choose Edit Server List, then click on the Advanced Tab that will then be seen and choose Use Custom Port, then enter the proper port directly -- that port is probably Port 587, but that could depend on the advisory of the email provider for using their SMTP.

Apps work in one location but not another

Some apps (iheartradio and tvguide) work fine from my home wifi, but not in another wifi area (at work, which has better wifi). Other apps such as pandora work fine at both locations. What is the difference and how can I get all apps to work everywhere?

It's entirely possible that your employer has blocked certain ports on the corporate firewall, which will prevent some apps from working.

Store credit shows up on one computer, but not another

Happy Easter everyone,
I was wondering why my store credit shows up on one authorized computer, but not another? Is there a way to fix this? Or will I just have to make my purchases on that computer?
Thanks
Jason

An account's balance should show wherever you use the account (computer's iTunes, and in the App Store, iTunes store and iBookstore on iOS devices). Have you tried logging out and back into the account on the computer that it's not showing : Store > Sign Out menu option, that will then change to a Store > Sign In option (my balance has sometimes been slow to update on my computers/devices)

Safari works for one user but not another on same computer

MacBook with multiple user accounts. Safari (and Firefox) work fine for one user but are unable to open web pages when the other user is logged in. The error in Safar is "Safari can't open the page "http://xxxxxxxxx/" because it could not connect to the server "/xxxxxxx/" . DNS is working for this user. I am able to ping any number of sites from Terminal. Network Preference pane is configured to not require any proxy. This is a case of it was working but now it's not.
Can anybody help with this? I know I can fix this by simply creating another user and transfering the affected user's data to the new account but I would rather not. TIA

HI Bob,
You can test your settings by clicking the big "Test My DNS" button at <https://www.dns-oarc.net/oarc/services/dnsentropy>. If you see "Poor" on any of the tests, don't use that domain name server! Remove it from Apple Menu => System Preferences =>Network =>DNS Servers or similar location in your router if you've got a 'home network'. If all you have is "poor" DNS servers in your list, call your ISP and insist that they give you the address of a name server which is protected against the recently exposed DNS cache-poisoning threat.
Also, open System Preferences/Network. Click the DNS tab. Add these numbers in the DNS Servers box.

Jabber 4.4 "Graphics card or driver not supported" error on one machine but not another.

Hi, I looked at the KB document but the email link on it no longer works.
I have two end-users using Jabber 4.4 on identical machines, same specs, same driver build and OS image. One gets the "Graphics card or driver not supported" error, the other does not.
We have two DellOptiPlex 7010's,
Both had 2 instances of AMD Radeon HD 7470 - they are dual monitor machines.
In both cases the driver version 8.922.0.0, Driver Date 12/6/2011. This is the latest Dell has on their website.
On one machine when I run a fresh install for Jabber for TelePresence 4.4 it works fine. But on another the user first gets
"supportabilitytest.exe has stopped working
A oriblem cause the program to stop working correctly. Please close the program."
Then when that's closed out we get:
"Graphics card or driver not supported!
New features in this version of Jabber Video are not supported by your computer's graphics driver.
Update to the newest graphics driver available and run Jabber Video again."
I can't believe it's just a matter of upgrading the drivers because in this case one machine with identical drivers works.
I appreciate any insights, thanks !

Hi ksouthall,
It sounds like the openGL supported version did not install on the one that is failing. There isn't much we can do regarding that error. Best practice is to always upgrade to the latest manufacturer's available driver. Client requirements are below.
Windows 7 (32-bit or 64-bit), Vista, or XP (SP 2 or newer), with OpenGL 1.2 or newer.
For 720p HD video calls, Intel Core2Duo @ 1.2GHz or better.
For VGA video calls, Intel Atom @ 1.6GHz or better.
Webcam, built-in or external. You need an HD webcam if you want other callers to see you in HD.
Broadband Internet connection with a recommended bandwidth of 768kbps upstream and downstream. You need about 1.2Mbps upstream and downstream for 720p HD video calls.

Jason

Smb error -36 on one server but not another (vpn)

Here goes:
I'm connecting using the built-in Apple VPN client to work.
Once connected, I try to mount two Windows servers using the finder:
* The first one asks my username/password and mounts no problem.
* The 2nd doesn't seem to ask for username/password, and just gives me the dreaded "error -36"
The console says:
Unknown host
mount_smbfs: can't get server address: syserr = Network is down
mount_smbfs: can't get server address 'XXXXXXXXXXX'
But the network is up (I know, since I am moving files from the other server).
When connecting from inside the office (not via VPN) all is well.
What gives?
