Random connection issue

Hi Guys,
For some reason all users on a 10.5 box can't log in, gives the invalid user name or password error, then it seems to work again after awhile.
Server running DNS, OD Master, AFP & SMB
Screen sharing works 100%, just random issues with file sharing. SMB works fine, just happens when connecting via AFP.

Hi
As far as I know this unit was delivered with the Atheros WLan card.
Usually the Atheros client utility should be preinstalled on this unit and should be use to configure the WLan connection and options.
I dont know if you use it, but if not check it.
Furthermore I would recommend checking the WLan driver version. Maybe a new release is available on the Toshiba website.
However, mostly the hardware compatibility between the WLan router and the WLan card is responsible for such issues (connection delays, etc)

Random Connectivity Issues with Time Capsule

I am having random connectivity issues with my time capsule with my intel based iMac. I don't have any issues with my MacAir, iPads or iPhones... just the iMac. It shows a "good" connection but sometimes... TC won't be able to connect to run a backup or I can't get to the internet. It doesn't appear to be an internet problem as I can get to the internet on other devices. It appears to be a connection issue between the iMAC and the TC. Thoughts or suggestions?

Do a full reset of the iMac.. apparently after the latest Mountain Lion update it can cause issues. I have not needed to try this as I have not seen it myself but I track the treads very closely and this popped up.

Windows 8 And Random Connectivity Issues

Hello,
I just relatively recently got a laptop with Windows 8 on it. I hadn't used Windows 8 before, but while some features are good, others are not.
Notably, when I put my computer to sleep and return from sleep, often times I need to unplug my ethernet cable or my pages won't 'load' because the network is unavailable. But my old laptop, with Windows 7, will be able to access the internet just fine and
so it doesn't seem to be an ISP issue.
I thought it may be a Google Chrome issue, but IE and Firefox have similar issues, pages hang for a long time and eventually display 'page cannot be displayed' or some variant.
As I said, sometimes if I unplug and re-plug my ethernet cable in, it resolves it, at least when I return from hibernation.
Unfortunately, two or three times before, and now another time today, I'll be working on my computer and I'll go to a website and it will just hang, then if I try to reload or reload any other pages, I get a similar issue, the network isn't available.
I tried unplugging/replugging, I made sure the connection was fine by using my old laptop, and I even tried putting the computer to sleep and back, and closing Chrome and reloading, none of that worked. What did work was completely restarting, but this is
inconvenient.
I'm just wondering if anyone else has encountered these issues and if there are easier/more permanent fixes to them? They aren't /terrible/ but they are inconvenient and annoying.

Hi,
Have we tried the network troubleshooter?
Open the Network troubleshooter by swiping in from the right edge of the screen, tapping
Search (or if you're using a mouse, pointing to the upper-right corner of the screen, moving the mouse pointer down, and then clicking
Search), entering network troubleshooter in the search box, tapping or clicking
Settings, and then tapping or clicking Identify and repair network problems.

E3200 Random Connection Issues

Hi folks,
I've had this router now for close to a year and all of a sudden, I'm having problems with wireless connections. On our Android phones (about the only thing we connect with wirelessly) signal and connection will be there at times, other times it will not be. You can put the phone right next to the router and it will get signal. Move the phone away, a couple of feet and the signal disappears. Rebooting the router seems to help, but sometimes for only a few minutes, then the problem reappears. I've upgraded the unit to the latest firmware, but that didn't improve the issue.
Again... it's been fine for a long time until just now... And the problem is somewhat intermittent, but access is mostly down.
Thanks for any thoughts or suggestions.

There might be some settings required in the router so that it gets the proper solution. If you are facing the concern of getting lag, dropped connections then you can try the following steps:
A] With the help of Cisco Connect Software (if at all you have installed the router with the help of this software)
1] Open the software and go to the option which says "Router Settings"
2] Then click on the option which says "Advanced Settings" which will take you to the router's configuration page.
3] Lower the MTU (Maximum Transmission Unit) from 1500 to 1400 or less (usually found on your router's main/ basic setup page)
4] Then go to the Wireless tab, keep network mode as mixed,
For Channel Settings of 2.4 GHz you can make Channel Width to 20 MHz only and Channel to 6, 9, 11..
For Channel Settings of 5 GHz you can make Channel Width to 20 MHz only and Channel to 40 or 161...
B] If you haven't installed Cisco Connect then you can log on to the router's user interface using it's default IP address in the browser which is 192.168.1.1 and type in 'admin' as the password leaving the username field blank. This will take you to the router's web interface and then follow steps as mentioned above to make the changes.
You should also make sure you upgrade the drivers for the WLAN card on your laptop computers.
Second, for best results, wireless-N routers should be paired with wireless-N adapters in the same way that wireless-G routers should be paired with wireless-G adapters.

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:

Random USB connectivity issues

I have a 30GB iPod that randomly connects / disconnects. I can repeat the issue on 2 separate systems with 2 different cables. it's almost like the internal dock connector is messed up.
I will be playing a song (with the USB charging and the ipod NOT mounted) and randomly the iPod will connect and then promptly fail on the Mac with the 'device removal warning' as if i had just pulled the cable with out unmounting the drive.
Just curious if any one else has seen this before i head for a service call.

Can't say I've ever seen that posted here, and it's never happened to me.
I often leave my iPod(s) charging whilst I'm working on my Mac and I can even move the iPod around slightly in the dock and/or fiddle with the cable and it does not re-connect.
Might be a dodgy connector pin. Not sure what to suggest except service.

Random connection dropout issues, stumped the cable guy!

Hi, we just got our internet upgraded and it is blazing fast. We are now using a Cisco DOCSIS 3.0 modem with speeds up to 50mbps.
The bad news is that my Macbook and Mac Mini have started having random dropout issues. It is running really fast (almost instant webpages) and then sits when trying to load a page for a long time. Generally, it's when I try to go to a page and nothing is loaded yet. It says "sending request" at the bottom-left side of the screen. Here's some more details about it:
- It seems to only be a problem on the mac platform. My wife has a Win 7 PC and she has had no problems. They cable guy also tested his PC with no problem.
- It happens BOTH wired and wirelessly. Same dropout issues.
- It didn't happen with the previous, comparatively slower cable modem
- It seems to happen randomly on both the Macbook and Mac Mini
- It happens no matter what browser I use. I tried Chrome, Safari, and Firefox
- It may work for a long time, like half a day, and then start acting up again. I can usually get it to start happening if I try to open a lot of tabs and load pages consecutively.
My cable provider is going to check with some people and get back to me after the weekend, but so far he is stumped.
Anyone have any ideas what to try?
Thanks!!

My brand new mac pro always had Internet connection issues at school. WHY is that? I see the school's Internet working perfectly fine on other PC's, but there is never a day where my mac doesn't have Internet connection issues at school. How do I fix it?

I got my mac pro in the middle of August. School started the week after. Internet was working perfectly fine at home. But at school, I never had a good connection. Sometimes on the good days I get a connection when I'm sitting at the exact spot in class I always sit at. It's ridiculous and it's frustrating. I invested my money into this laptop and I'm beginning to regret it. I thought it was the school's Internet, but I don't see Internet issues with other PC users. It's most frustrating on registration days and I'm trying to register for my classes before it gets taken, but again... Internet connection issues. It's random. Majority of the time, it doesn't work at all. I've done Network Diagnosis and turning WiFi off then turning it on again. I've done everything I could. I put my money on this laptop and it was a lot of money. I could have bought an 800 dollars laptop and I would have Internet connection anywhere on campus. So, I don't want to continue everyday to regret on buying this laptop every time I try to connect to the Internet at school or Starbucks or anywhere else. How do I fix this? What's the problem ?
At school, I heard this guy had a problem with Internet connections too and he owned a new mac book pro. He said something like Apple messed up on something, but he fixed it. If I knew mac book pro's had these issues I wouldn't have bought it in the first place. It's freezing on me every other day. It's ridiculous. But what concerns me the most is the Internet connection. So someone please tell me what can I do next to prevent the problem? Am I doing something wrong maybe?

Hi Kevin,
I'm using an XLR input mic which is connected to the phantom power enabled XLR mic socket on a USB M-Audio M-Track. The M-Track is connected by USB to the Mac Pro - so effectively I've got an M-Audio USB soundcard with a mic input. I've also tried a microphone that is a straight XLR to USB cable (guessing with some soundcard chip buried in the usb plug) but that also yields the same effect of bad latency, intermittent quality, stuttering and repeating and echoing (without the speakers on during record so its not feedback).
The mic works absolutely fine with other recording applications I have on the mac at the moment - albeit non-adobe ones (tested it on the EasyAudioRecorder - and it lives up to its name. it's easy)
I will try with Audition and report back, but sitting here right now I can imagine it would work fine with audition too - it just seems to be the way premiere is set up for recording into the timeline is a bit sketchy. I'm willing to accept it might well be a quirk with the new Mac Pro trashcan - I'm not weighting all the woes on premiere.
Any thoughts or am I out of luck to sit with my fingers crossed for a fix in the next round of updates?
Nathan.

PS Vita Connection Issues on EA6500

I have a similar issue as a post I read entitled "ssid not visible" For the past six months I've had my PS Vita randomly connect and disconnect from the network. What happens is when I check the network it sees a strong locked signal but has no ssid when I try to connect to it I get an error saying ssid problems. Now this only happens with my Vita I have 2 PS3's an Xbox 360 Ipone Ipad Ipods Apple TV Roku etc. None of the other devices have this problem so one would assume its the Vita but the Vita only has this problem on this router other places it works flawlessly. You might ask why haven't you looked into this sooner well the Vita is a portable device im not using it at home to often no big deal also I did contact Sony because all the other devices work but there say because the vita can see ssid's of other netwoks right from in my home its not the Vita well I just got the PS4 yesterday and wouldn't you know it the exact same issue. Who's got to fix this Sony or Linksys?

Hi, william.bors. Have your tried manually adding or creating the wirless profile on your device?

Touch to Express connection issue

I am using Airport Express with iPod touch 5.0.1, to play music and Pandora through my home stereo. The connection will work great for a day or two with no interruptions and then begin to intermittently drop to the point that it will no longer reconnect. After a day or two I will go back to it and it may or may not work. Very random. The rest of my wifi is very stable, its seems to only be a problem between the touch and express. Any ideas how I can remedy this connection issue? Thanks!

Bluetooth randomly connecting to devices?

Been having this weird issue in our office. I have a 2014 MBP running Yosemite, and there are 2 new iMacs and a nMPro on the same network also running Yosemite. One of my partners also has a Bose Bluetooth speaker. FYI the other Macs and I all have bluetooth Magic Mouses.
My MBP has been randomly connecting to these other Macs/devices randomly, on it's own. The other Macs will show up as a connected device, even though I have never connected to any of them previously (nor would I, since there's no good reason to connect to them via BT since we're all on the same network already). The Bluetooth speaker is a device I've connected to in the past, but it's automatically connecting to it and that's annoying; just today he was listening to music through it from his MBP (running 10.8) and my MBP interrupted that and attempted to take over the speaker from his Mac.
Previously I found a post about deleting some BT prefs to knock off the connecting to other Macs -- but the article blamed this on the other machines, not mine. I'm starting to wonder if it's not me though; is there something I should delete on my end to clear this mess up?
TIA,
JVK

The only thing I can think of is to reset the device(s).
Be sure, of course, that Bluetooth is set to on.
What are you trying to connect?

Exchange 2010 SP3 Rollup 8v2 causes client connectivity issues

I installed SP3 Rollup 8v2 this weekend, going from 7. Since then we are having random client connectivity issues. New profiles can't be created, and some users can't access resources when booking meetings. We can do a registry fix to their machines to add
a DS Server, but this is a workaround only. I have uninstalled the Rollup 8v2 and we are still having the issue.
I thought 8v2 was supposed to fix this issue!

Hi,
According to your post, I understand that outlook client cannot connect to Exchange server to configure profile and cannot get list of resources room when upgrade to Exchange 2010 SP3 Rollup 8v2, the temporary solution is that specify the DC in registry.
If I misunderstand your concern, please do not hesitate to let me know.
Is there error message when configure Outlook failed?
Please run Test E-mail AutoConfiguration and Outlook connection status to double confirm the URL and FQDN of Exchange server.
As additional, please run below command to double check the state of Exchange system component:
Get-ServerComponentstate -Identity “servername”
If the state is Inactive, please run below command to active relevant component:
Set-ServerComponentState <Identity> -Component “component name” -Requester HealthAPI -State Active

WAP610N connectivity issues

I have installed 4 of these units in a commercial premises offering free wifi. Since the day they were installed (5Months ago) we had connectivity issues with mobile devices. This was somewhat resolved in the latest FW 1.0.04 but we are still having random disconnections on the units every 2 - 4 days and have to reboot the units.
Lately the units have become unresponsive and reset themselves back to factory settings.
What we have done so far:
Changed router models - No change
Changed from Static IPs & DHCP - No change
Turned on isolation - No change
Performed a wifi analysis to pick the best channel for each unit - Slight signal gain but still disconnects
Changed to 20Mhz only (And all other variations) - No change
I think I am left with no option but to return these for some other brand. Any suggestions are really appreciated. I'm really regretting buying these units at the minute...

I have tried every method of security available and these various levels have led to additional problems. While using WEP - devices got the message incorrect password after a day or so and while using any other there were a lot of random disconnects as well as some mobile devices simply being refused connection.
Using the units unsecured was by far the most successful but still gave the problems described in my original post.
I'm still open to any suggestions though!
Thanks

How about your try to call the tech support and see what they can further do about your concern.

Mail - random connections

My mail keeps going off line and gives me a message that there is a problem with port 110. But then it randomly comes back and sends/receives emails. This has been happening very sporadically over the last few weeks, but today it is even worse. The Safari internet connection remains ok throughout. Could I have changed a setting without realising it? Why is it happening randomly? Linda.

Lindart,
Since this is happening on port 110, I am going to assume it is a POP3 account. Do you check this account from any other computer or device? And if so, could that be trying to access the mail account at the same time?
This article was written for iPhone, but applies to any POP3 account being accessed from more than one email program:
http://docs.info.apple.com/article.html?artnum=307009
If you are getting errors similar to those in that article, it could indicate a connection issue, or a large message that is causing your mail client to time out. If Mail reconnects before the server has timed out, the server will see that as two connections, and generate the same kind of errors.
Hope this helps,
Nathan C.

WRT54G + SpeedStream 5100 Connection Issues

I have a WRT54G, which I used at school in NY for about 4 months with no issues. When I brought it home, I hooked it up to our DSL modem. The current setup is a cord from the wall to the modem, modem to router, and router to computer.
We have one desktop comp that is wired directly to the router (as just mentioned), and 2 wireless laptops, only one of which is used on a regular basis. All three computers are Macs. As soon as I set this all up, the internet connection began to drop (seemingly) randomly. All computers will lose access to the internet, and the only way to regain access is by power cycling everything. Through a week or so of observation, these are the causes for connection failure that I can come up with, although I'm not sure if they are the only ones, or if I am correct in my assuptions.
1) iChat - any use at all, but especially video chatting, will immediately cause the connection to drop. Skype, however, works for video chatting. This problem doesn't bug me so much because Skype works, plus I read that iChat doesnt support linksys routers. So whatever.
2)If the desktop computer is turned on while the laptop is running, both will lose connection. If the desktop is turned on first, however, both work fine. This caused me to wonder if the desktop somehow got set up with a static IP address that the laptop was taking if it got booted up first, but I cannot imagine how that would have happened, nor do I see any indication that it has happened.
I feel like there used to be a lot more random connection dropping, but that seems to have cleared up and these are the only things I can find that consistently cause connection to drop. When the connection drops, it is for all computers.
I called Tech support and Linksys had me change the MTU and a couple other things, which helped for a while, but not permanently. Then when it kept happening they told me to get a new router, but this one does seem to work fine, except for the above circumstances.
whew, sorry that was soooo long
Message Edited by joeshmoe5409 on 05-28-2008 08:36 PM

Bump. I'm really desperate here, I have to power cycle my router/modem/computer at least 2 or 3 times a day, sometimes as many as 10. I've tried talking to linksys - they had me change the MTU and a couple other settings, update the firmware, and change the channel. I cannot figure out for the life of me what the deal is here. It is especially bad this morning, has already dropped on me 3x. Any thoughts?
