IMac losing connecting for wireless after restart

Hi,
As subject suggests, i'm having a problem with the wireless after a restart. It's the new 2.4 24" imac.
I have had the same problem on 3 other imacs but cant remember how to solve it......
Something about deleting old connections and added it manually... anyway could someone point me to the link that apple published regarding this issue please?
Thanks
Darren

I have been having a similar issue with my early-2007 iMac 24. It often will not reconnect after having been asleep. Sometimes I can turn off and back on my wireless settings and it may reconnect. Sometimes I can reboot and it may reconnect. There are times like today, that I tried both several times and even the suggestions in the article you posted (even though I didn't know about the article). I finally got it reconnected this time by allowing my router to broadcast its SSID. I use two different routers since the Airport doesn't have much for me to control what Websites my children have access to, so I will try to experiment with both to see if the iMac will more reliably detect the one that broadcasts its SSID. I started on this line of thinking, because my iMac also gives me a list of other available networks of neighbors when it will not connect to my own routers even though I can connect to the routers with other computers using the same wireless settings.

Consistently losing connection to NAS after error:

Hi
Win 8.1 (happened in 8 too). Lose connection to WD MyCloud that only corrects after a computer restart (nothing done to the MyCloud). The error is:
A fatal alert was generated and sent to the remote endpoint. This may result in termination of the connection. The TLS protocol defined fatal error code is 10. The Windows SChannel error state is 10.
Any help would be appreciated!!

That device is unsuitable for use with Time Machine. I know the vendor says otherwise.

Possible fix for OS X 10.5.7, losing connection after sleep, restart

Possible fix for OS X 10.5.7, Airport, losing connection after sleep, restart, or cold reboot.
Issue: (For OS X 10.5.7 on iMac5,1, Intel Core 2 Duo)
=============================================
- After sleep, restart, cold reboot, even though cannot connect to Internet, but the AirPort bars are still full, as if connected.
- Losing Internet connection after sleep, restart, cold reboot.
Possible Fix:
1.Open Network Preference, click on the Location drop down list > Edit Location... > click on the wheel button > Duplicate Location.
a)Select this newly setup location; Use Diagnostic button to connect to the internet. Select Network or enter WEP password if necessary.
b)Test to make sure you can connect to a web page.
c)Go to sleep & wake up.
d)This time, the Airport bar will start to show correctly. Before, it will always be full even when not connected. Now there will be no bars or grey out when not connected.
2.On the left hand side of the Network Preference Window, there is a list of services, such as Airport, build-in ethernet, built-in FireWire, bluetooth, etc.
a)Click on the wheel button on the bottom of the service list; select Set Service Order...; move Airport to the top of the list.
b)Delete any services which you are sure that you are not going to use, such as Bluetooth, etc.
3.Pick one of the locations mentioned in #1, and make it sure it is connected. If not, use Diagnostic button. If you have to select Network or enter WEP password to connect, make it so.
a)Check to make sure you can connect to a web page.
4.Go to sleep & wake up. The Airport bar should be filled up quickly. Try to connect to a web page.
5.Restart computer. Test a web page.
6.Shut down & Start computer. Test a web page.
7.When everything is working fine, you can delete the extra location that you created in step #1.
8.Click the lock on the left lower corner of the Network Preference window to safeguard the setting.

If my assessment is correct, the LIDE 200 driver is version 14.8.1 and dated 26-Sep-2008. It is possible that the driver will not work with the latest version of OSX. I would advise that you contact Canon and ask them the question.
(Removed link because of the way Flash drives the Canon site).
It is not uncommon (though irritating) that devices no longer work when an OS is upgraded. One has to ask the question if (or why) the driver was not written in such a way as to be OS version independent.
Chris
I spoke to Canon over here in Australia. Not helpful at all. In fact they were about as useful as an ashtray on on motorcycle. Having said that the tech seemed to think that there would be an update soon. But that is assuming that Canon are aware that there is a problem with that Scanner under OS X 10.5.7.

Who can shed some light on my ongoing connection problem.
After upgrading my iPad Air with IOS 7.06, I could no longer connect to the internet.
I have 2 MacBooks Air, 1 ipad mini and one iPhone 4S running on the same network, and they are all connected to the net and function well.
So I cleaned up the ipad completely, installed the latest firmware and reinstalled my apps : no connection.
I tried all things of resets and forgets. No result.
I have been fondling with my Airport Extreme 5 , but that did not help much.
This morning I went to a neighbor , hooked my ipad air on his network, typed the password and the thing all worked fine.
I have tried to connect the ipad air as an ethernet client, but that did not work. „Not enough power“ was the statement
Ideas anyone ?

Yes I tried this manyfold. But did not work. Reading on, I took Tesserac's advice. Shut down router and computer.
Start router after 15 minutes and wait another 10 minutes before starting the computer.
Et voila.... everything is back in working order,

Internet Connection loss after losing connection between 2 sites

Hello,
I have started working for a company over a year ago and recently we are running into an issue with losing internet after a loss of connection between companies site. Below is a summary of setup.
Company has 2 locations, Site A and Site B..both same domain
Site A has DC and other servers such as ERP, Document Control Software.
Site B has DC, Printer Server, File Server and other essentials servers.
Each site has own independed 20 MB connection.
Site A and B are linked via MPLS and only used for ERP, Document Control software, and DC traffic.
Recently we started to have frequent connection issues with the MPLS and as a result I started to notice none of the users at Site B can access the internet such as google.com, msn.com...etc. As soon as MPLS connection is restored interent works.
The DC at Site B was setup before I started working for company.
I have been trying for the past few days to figure out why Site B is losing connection when MPLS Tunnel is not operational...but so far no luck.
I am very sure that internet traffic is not routed via MPLS because when internet is working the IP lookup such as "whatismyipaddress.com" points to ISP IP address for site B. Also when doing tracert to external website the route is via ISP for
Site B.
I think this issue is related to DNS but cannot tell the cause or how to fix?
Thanks for assistance in advance.

Hi
Having said internet is not routing via MPLS, Even i think to be a DNS issues,
Try to check the below
Ensure all the client DNS is set to AD DNS server
In AD DNS server ensure its not forwarding DNS query to Other site
During outage check any client PC manually changing the DNS IP to 4.2.2.2
- all client DNS are set to AD DNS server
- I checked the properties for the AD DNS and found there are 3 forwarders listed.
The first IP is at Site A which is resolved.
The second IP I am not sure about since it is not even in our subnet (not resolved)
The 3rd IP seemed to be for an old DC that is no longer operational (not resolved).
- During outage if I change client machine DNS to 8.8.8.8 or 4.2.2.2 they can access the internet.
I guess my issue is with the forwarders. Would the right step be remove all 3 forwarded and add 8.8.8.8 and 4.2.2.2?
Thanks.

Questions About Losing Connection

Like other people I've noticed here, my WRTG45 v5 wireless router has recently started losing connection to the net multiple times a day. At first, we thought it was because our modem was old, so we bought a new one, but it didn't fix anything. So here are my questions:
1. My dad seems to think that a configuration or setup CD (that we lost) is required to make the router work with the new modem. Is this true? I don't think so, but I have to ask just so I can get him to move on.
2. I noticed in other posts here that programs like Bittorrent can cause the router to be overworked or whatever. This might explain our problem, as I use Bittorrent a lot (but not everytime the connection has dropped). If this is indeed the problem (or contributing to it), is there anyway to deal with it while still being able to use the program?
For the first couple months, the router was working fine. Even with Bittorrent running a lot, and all the computers (2 wired, 1 wireless, and 1 wired X-Box) engaging in various activities on the net. So this is very puzzling to me.
One more bit of information, I have given every computer a unique, static IP address. However, I noticed recently that when I look at the router configution after typing in its IP address in a web browser, that it is set to DHCP Enabled.
Also, in the advanced TCP/IP settings for this connection, under the WNS tab, the NetBIOS setting is set to the default of using NetBIOS from the DCHP server.
Since I am using static IP addresses, could these DHCP centered settings be causing problems? Although, even if they are, it still doesn't explain why the router was working fine months ago (unless someone changed stuff without my knowing).
Anyway, any help at all would be appreciated.

I assume you meant that you had a WRT54G v5 router.
First of all, the setup CD is not required. All router settings can be made by going to the router's web pages at 192.168.1.1
It is possible that the static LAN IP addresses are causing your problem, if they were not set up correctly. Linksys has a strict set of rules to follow regarding static LAN IP addresses.
With Linksys routers, a fixed (static) LAN IP addresses must be assigned in the device that is using the address. So you need to enter the fixed address in the computer or printer, not in the router.
When using a Linksys router, any fixed LAN IP address must be outside the DHCP server range (typically 192.168.1.100 thru 192.168.1.149), and it cannot end in 0, 1, or 255.
Therefore any fixed LAN IP address would normally need to be in the range of
192.168.1.2      thru 192.168.1.99 or
192.168.1.150 thru 192.168.1.254
assuming you are still using the default DHCP server range.
Also, in the computer, when you set up a static LAN IP address, you would need to set the "Subnet mask" to 255.255.255.0 and the "Default Gateway" to 192.168.1.1
It is also important that no two devices on your network be set to the same static LAN IP address.
Check all of your static LAN IP addresses. If you have violated any of the above rules for static LAN IP addresses, it could be the cause for your problem, and you should fix it before attempting any other router repairs or changes.
You should leave the DHCP server turned on. This way, if you have a visiting friend who you want to connect to your system, it will be easy to do.   Leaving the DHCP server turned on should not cause any problems, even if all your addresses are fixed. In general, you should let the DHCP server assign all addresses, unless there is a specific reason to use a static address. You can mix static and DHCP assigned addresses on the same LAN, as long as you follow the above rules for static addresses.
Linksys routers have had problems when BitTorrent is used. Your router has new firmware posted that should improve compatibility with BitTorrent. It is firmware version 1.02.0   You will need to download and install this firmware (after fixing the static address problem, if any). (Note: When you update your firmware, you should use a computer that is wired to the router. Also, when you do a firmware upgrade, turn off all other computers on your system, and unplug all other wires from the router.) After you have installed the firmware, and powercycled the router, you will need to reset your router to factory defaults, then setup the router again from scratch.

DI Connect to SBO after load from Transaction Notification

Hi all,
I saw few posts on this issue.
I want to connect to SBO after class was loaded by TN.
SBO and DLL hang.
someone solved it using SQLAgent - please explain..?
is there any other solution??

Hi Yaniv,
I also had the same problem. What I did is read a bit about the DI Event Service <a href="https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/53cefa6a-0a01-0010-cd8e-e7c189cb6519">SAP Business One DI Event Service</a>
and modified the <a href="https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/business_packages/a1-8-4/b1dieventservice.zip">Source Code</a>. What it does is use a dll that gets the data from the TN. Then a service creates a thread that communicates with this dll by sockets and gets the data. In this thread you can connect to DI API without problems. This service has .NET Remoting and MSMQ capabilities, that I removed, because I only wanted all to run in the server (and also had problems with MSMQ).
Anyway, the original program is very good, but it needs to have more documentation about MSMQ.
Hope this helps,
Ian

Lag in connecting to network after waking

Is it normal that my MacBook Pro has a long lag to reconnect to my home Network (both wireless and hardwired) after waking from sleep? But, if I'm using other apps and then launch Mail or Internet its instantaneous. I have Fios internet via Cat 5 and also AE wireless. Having only one type of connection on doesn't change anything.
Thanks in advance

Yes, I do have vmware vs 2.07 installed, but I only use it for a coffee roasting program. No, I don't have the log out option checked and the router is from Verizon Fios a, Westell A90-9100EM15-10 Rev A
I don't use the wireless part of it as I already had an Airport Extreme. I don't notice any problems as discussed in the vm thread about losing connection but now that I think of it maybe that's the reason I've been having trouble getting uninterrupted playback from Pandora and Last fm when using Airfoil or iTunes. But then the other day that started working fine. Hmmm.

WRE54G losing connection to either router or PCI?

I have a WRT54GS V6 router, a WMP54GS pci card and now a WRE54G V3 Expander all with latest firmare. Router is downstairs and coverage is fine for most of upstairs but my bedroom is about 20 feet down a hallway and signal is low (and sometimes non-existent) in this bedroom.
Have set the expander up properly following the many links on this support forum and when I first plug it in, everything is fine. Blue lights on, my bedroom PC says "excellent" signal with 54mbps speed and internet works great. After about 10 minutes though I can't access any websites or connect to expander through browser. All of this time, the lights are still blue and my PC still has 5 bars and excellent signal strength. If I try repairing connection, it will connect again with a low signal and not allow me to access expander settings so I'm assuming it's bypassing expander and connecting to router rather than expander. The only way to connect again to expander is to power it down and on again and I'm then back to a great signal for 10 minutes.
Things I've tried after searching the forum:
- tried different channels
- assigned new IP address to expander
- enabled mac filtering on router to stop PC from bypassing expander and
reconnecting to router. In this case, same problem but then can't repair/connect to router and must restart expander to connect to it.
- tried setting a different SSID on expander and setting PC to connect to only that one.
- turned off power saving mode in settings of my PCI card (via device manager)
- moving expander to different places. If I place it at top of stairs, the signal in my bedroom is not great. If I place it in my bedroom next to computer, signal is great. Either way though, the same problem happens after 10 minutes or so.
Aside from resetting the expander and following all of the the setup instructions again (which I've done about 5 times now), is there anything else I can do?
Thanks.

Hi,
Thanks for reply. No, I'm not losing connection to internet when I'm not using the repeater. It's only when I add the repeater to the mix do I lose the internet connection along with connection to the repeater.
Called Linksys today and they first advised me to re-flash the firmware even though it had the latest version. No change. They then told me to try to wall power plate rather than the AC wire connection. Not sure what that has to do with it but will try it.
I bought this unit a few weeks ago via Amazon for $35 as a refurbished unit. I'm starting to think I just got a lemon. Unfortunately, the actual seller was Amazon but some other reseller that doesn't accept returns on refurbished units.
I will try WEP but to be honest, I really don't want the unit if it doesn't support WPA as it's supposed to. And yes, I have assigned a static IP and gateway. I also tried changing the computers gateway to the IP address of the repeater (read that suggestion somewhere) but again, no luck.

Recent problem: clients are losing connection to AMS 5.0.1

For the past week, since Oct 14, we've been having issues with clients losing connection to our AMS application. We have online classes that include a chat room and sometimes an audio stream from the instructor. This application and its server has been running stable for months... until last week.
One of our staff was connected to the app, getting everything set up for a class, and she started complaining of getting disconnected. I looked in the application logs and noticed that the application.onDisconnect was being triggered. However, the client didn't register that it had been disconnected for several seconds afterward. She let me know when she got the "Diconnected" message on her screen, which comes from the NetConnection.onStatus handler.
The only other sign of a problem is that in the server's core logs we started getting the following error when we checked bandwidth:
> Invalid command message data: unexpected bw response from client 000000001D670170
The client number changes frequently, so I'm guessing that this is first happening to one person and then another. We don't think that this bandwidth check is causing the disconnects because we rolled back to a previous version that didn't have it. The disconnects still happened after using the old version. What makes it frustrating is that it hasn't happened to anyone on the dev team, regardless of which network we've connected from. Also, the code hasn't changed on the client or the server, and to my knowledge, we're still using the same configs for months.
The AMS is v5.0.1, the client is written is AS2 and targets Flash Player 11.4.
The affected Flash Players reported are 15.0.0.152 and 15.0.0.189, in browsers IE, Firefox, and Chrome, but not all installations are affected.
Is there anything else I can look at to determine what the problem is? Does anybody have any insight as to what might be suddenly affecting our AMS app?
Many thanks,
Nick

Yes, we came to the same conclusion about the unexpected bw. We realize that it is not causing the issue, but I included it because it started happening at the same time and thought that they might be caused by the same issue.
We have been trying to come up with what changed to cause this, and aren't coming up with anything.
We have been on 5.0.1 for at least 5 months, no changes there.
We haven't updated the main.asc since 9/16.
The VM that runs our server is still the same, and AMS config files haven't been touched.
The client swf had a change 2 weeks ago, but we've reverted the change and are now using the old swf again.
The person who initially reported the problem was using the same computer that she's used many times to connect; she was going through her usual process to set up for the session.
You mentioned bad network, and that is another thing that I have been looking into, but our IT department says that we haven't seen any huge increase in bandwidth usage, and that everything looks to be within normal operating ranges
