Timeout in connection?

I've set up my network in a pretty standard manner as my wireless acceess-point with wpa2 personal encryption. But time and time again I'm suddenly asked for the password when trying to log on, and when I write it, it thinks for a while and then I'm told "timeout in connection". The only thing that helps is a factory reset – any ideas?

Hi Ka7lm1011,
which does the function return the error code ERROR_INTERNET_CONNECTION_ABORTED?
Does this error appear when you start download the 500M file or after start download? 
I suggeste you would better to check this root of this problem is  on the client or server side. Have your tried some ftp tools to download the specify 500M file? If yes, there should be something wrong with your ftp server.
Best regards,
Shu Hu

    Hello Gidion,
    can you please verify the hostnames/FQDN's? Because:
    LOCATION SAP-Gateway on host hemisrq.services.retail.tc.services.retail.tc / sapgw01
    host hemisrq.services.retail.tc.services.retail.tc
    It seems to me that somewhere the domain is double used.
    Additionally:
    Sometime there is sapgw 01, sometime sapdp 02. Can you please check the correct service numbers / system numbers?
    Regards
    Holger

  • Timeouts and connection problems after 5.1(2) upgrade

    AIM/chat and some other programs are having timeout/connection problems after upgrade to 5.1(2). I am using S241 also. The connection problems stopped when the IPS was set to bypass. Rebuilt IPS and left sigs at default settings and problem is still happening. I am not seeing any of the IPs that are having the problem in the Event Viewer or on the Events in the IDM.
    Any known issues with the 5.1(2) that would cause this type of problem?

    I don't know specifically, but I did notice that 5.1(3) was released today.

  • 10.7.3 MBP Wifi Problem - Endless Timeouts & Dropped connections

    I've been reading around here a bit already and so I know many other people are having Wifi issues with Lion, but given that there are so many discussions and so many pages of talk, it's hard to go through it all, and using the search I haven't found anything that's quite similar to what I'm experiencing, so I'm starting a new topic...
    Basically, I've got a late 2006 MacBook Pro, installed 10.7.1 (form 10.6.8) on in back in Aug 2011 and everything seemed to be fine. I updated to 10.7.2 sometime in Jan and still didn't notice any issues, but wasn't using Wifi at all at the time.
    Then in Feb I moved and started using wifi (with a Cisco N router), and noticed that often, the system would not automatically reconnect to the network after waking up from sleep. Just selecting the network manually worked on the first try every time though, so it wasn't so bad.
    At the end of April, I finally got around to installing the 10.7.3 update. I read it was supposed to fix wifi issues and so was looking forward to it. It installed fine and didn't seem to cause any problems...
    2 days later I moved again (to India), and all **** broke loose... Now, I can rarely connect to wifi (a Beetel G router, configed with WPA). Around 25% of the time, the network won't show up in the list (despite being a clear 5ft from the base station), and when it does show up, 95% of the time I get a "connection timeout" error - often immeadiately, but sometimes it takes about 10sec to respond. On the same network, 2 Win 7 Dells and an iPad 1 all work flawlessly - it's not the router...
    One the occasions that I am able to connect, it usually works fine, but if I put the computer to sleep and wake up again, there's no guarentee that the connection will work again - it's back to the lottery. And sometimes even when it's connected, the wifi stays (according to the menu indicator) but the internet connection disappears (to the point I can't even ping the router - 100% packet loss, let alone any internet server)
    I've tried zapping everything I can think of (PRAM, SMC), repairing permissions, clearing the remembered networks from the System Prefs, deleting old Locations and creating new ones etc. I have a clean install of 10.7.1 that I booted off of, but it still had the same issues!

    I'm pretty savy with computers and have dealt with all kinds of stuff before, but this one is beyond me, and is really annoying! I konw my machine is old, but it was totally useable up until these Wifi issues, and now wifi is basically useless.
    From what I've read, it seems like its a driver issue with the Atheros card in my machine, but most people seem to be complaining about dropped connections (mine rarely drops) rather than timeout connection issues. I've also never had the "hardware not found" issue that many people have, so I think this is something different.
    Anyone out there have any advice? I'm getting close to losing it with wifi since the update!

    Sorry - to add:
    I don't think it's a question of WPA vs. WPA2, or even channel number - I have 2 identical routers here and neither work (both default to WPA Ch 11) but I changed one to WPA2, new SSID, various channels and still had the same problems.
    Another thing to note that should be irrelevant, but who knows: the Firewire controller on my machine died back in Fall 2010 - to the point where the system won't start-up unless I remove the IOFirewire***.kext from /System/Library/Extensions , and as soon as I do that, it works flawlessly (minus Firewire). It meant I had a **** of a time installing Lion becuase I can't boot off the Recovery Partition (which has the drivers baked into it), but by cloneing my HD, installing Lion onto the clone via a borrowed machine, removing the .kext's and cloning back, I got it on and everything seems to be fine otherwise... I posted about that problem before, but never got any answers. And it wasn't just me, my father has a late 2007 MBP and the same firewire issue happened to his within 5 days of mine (not a power spike - I think it was shortly after some system update if I remember correctly).

  • Because of a POLL() Timeout, Listener Connection to a DB Takes Long Time!

    Envionment: OS: OEL5.3 (2.6.18-128.el5Xen) x86-64bit RDBMS: 11.1.0.7 (in an OVM setup)
    The Problem:
    It takes more than 10 seconds to get connected to the 11.1.0.7 database using SQL*Net with dedicated servers.
    Points to consider:
    0. I posted this in DB (Net) forum as well.
    1. Direct local connection has no such issue.
    2. Connection to a 10.2.0.4 database on the same server is no problem either (direct as well as through SQL*Net)
    3. Only dedicated connection takes such a long time. With shared servers, the connection is quick again.
    4. Using prespawned servers does not help.
    5. Connection is quick with another 11.1.0.7 on the same network (another guest on the same OVM server, but it is 32-bit: OEL4.3 / 2.6.9-55.0.12.9.1 ELxenU)
    When I ran strace on the client as well as on listener (using: strace -T -tt -ff -o <outputfile> -p <pid>), the client process took the longest time waiting for a read() call to finish (about 10 seconds), and by looking at the entries with the same timestamp from the listener side straces, I found the following entries from the shadow process:
    11:41:01.095138 poll({fd=10, events=POLLIN}, 1, 4769) = 0 (Timeout) <4.768228>
    11:41:06.086246 poll({fd=10, events=POLLIN}, 1, 4777) = 0 (Timeout) <4.777516>
    As we can see, these timeouts together account for more than 9.5 seconds out of 10.x seconds total elapsed time.
    Any clue why this happens (and why not in other cases listed above)? More important, how to get this resolved? __If decreasing the timeout value for the POLL call could be a workaround, how can I achieve that in OEL5.3?_
    Appreciate all your help and suggestions.
    Thanks and regards,
    Govardhanan.

    I've updated my profile to show my email address, so go ahead and email me the strace output (compressed please). Maximum attachment size for emails to Oracle is 10MB (encoded), so split the strace output in 5MB chunks if necessary.
    poll() is not normally used by the Oracle network layer for client-server connections. So this may be related to an OS network service, such as DNS or NIS. The strace should make this clear (to me anyway).

  • Five months of ongoing timeouts and connection loss

    SE PA area. Problem started back in January with bursts of high ping times and timeouts on an old white Westell model with a WRT54g bridged to handle the routing. After several support calls a new Westell 6100 was sent but failed to resolve the intermittent problem. It seems to be aggravated by wet weather but also happens during dry periods just not as frequently. Around March tech support sent another Westell 6100 claiming the first one went bad. Problems continued intermittently as they've always been.
    After a couple more calls to tech support they claimed the second Westell 6100 might be causing the problem and sent an Actiontec GT704WGB. Before getting the Actiontec installed our phone quit working (clicking noise and cross talk) but DSL continued to function with the same high pings and time outs randomly. This was last week and we were finally able to get a phone tech last Thursday (still had the Westell 6100 hooked up) to come to the house. Several hours prior to his arrival our phone started working and talking to the tech he said there was a line problem found and fixed.
    While the tech was here, he put a splitter in line and ran a home run for the DSL to help us eliminate any possible filter issues and see if it would help with the intermittent DSL problems. I have also replaced the line from the NID inside with a new cat5e run. Yesterday (Friday) we had a bad rain storm lasting several hours (over 1.5in of rain) and the DSL has been garbage since.
    I broke down today and pulled the Westell 6100 and my Linksys WRT54g out of the DSL line and finally installed the Actiontec GT704WGB and it's as bad or worse than ever. I've collected as much info as I can to try to shed some light on this if someone know how to interpret what the results are and can help, that would be awesome. I'm at my wits end with Indias tech support route and after 5 months I don't know what else to do.

    Ah.. I was hoping you'd stop by and chime in. Thanks!  I spent a couple of evenings browsing the forums looking at others' issues and was always impressed with not only your knowledge but your willingness and consistent help to many who post up with issues. I'm gonna have to give you a Kudos on this as it's the best I can do and people such as yourself and several of the other regular "assistees" I've seen help here are what really make these forums/communities the great resource that they are.
    As I have a technical background in electronics and electro-mechanical I was able to blow through a lot of good information on what to check and get all my potential infrastructure issues on my side covered before going any farther (replacing my old lines with new cat5 and new jacks, getting the tech to put a splitter in and run a home run for the DSL line). But I don't have much knowledge in the telecommunications end and DSL. Your info helped a lot with shedding some more light on that as well as reading other posts.
    I saw the Redback router in the reverser trace and had gathered from other reading that they're older units. I have no idea what if any upgrades will be done at my CO. I am in fact fed from a CO and that fits in with my attenuation numbers as I'm about 2 miles away. From the numbers I estimate between 12-13000 feet on the wire.
    A short update since Sunday. Yesterday my wife received a call from a US based tech from the Chronic Intermittency team (I think that's what she called them) and after looking at the line the nice lady was a bit perplexed as I was as the numbers look so good on the line. She was able to determine after several steps with my wife, that we might just be saturating the 1.7Mb we were provisioned at and the modem was just giving up the ghost and timing out eventually. She opened the pipe up to 3Mb and it's gotten MUCH better since yesterday. While it tightened us up quite a bit on the Margin (I was a little surprised at how much the Margin dropped with only doubling the rate) it appears 5Mbps would easily be doable barring no other line issues. What I was most favorably impressed with though was that the nice lady promised to call back and stay with this issue until resolved. She's off for a couple of days which will give us some time to see how much better this one change has improved things but she did call twice yesterday (a call back followup after the original call and bumping up the provisioning to see if she was on the right track). That certainly helped boost my confidence level with Verizon's support a bit...

    I also found it interesting that the upstream output power dropped so much. It appears that modem was getting a workout at 400Kbps. Downstream held the same.
    I'm not ready to mark this resolved yet but it does appear the lady was correct in her assumption that we were saturating the connection as a primary root cause. Interesting...
    What I still find a bit of a puzzle is our online habits haven't changed (always run virus/trojan protection as that was one item the tech queried due to the activity she was seeing based on what my wife had running at the time) and yet this didn't crop up until the beginning of this year. We primarily run 2 desktop systems and I use a laptop wirelessly occasionally (yes, I did kill the wireless on the router for a day in troubleshooting). My usage is primarily browsing and email and my browsing is mostly forums and finance based so not a lot of high bandwidth usage there. The wife does have an online game she's played for years and does use Skype and Teamspeak during her gaming, but her gaming habits/use hasn't changed over the years either. I do run the Network Meter Gadget on Windows 7 on all PCs so we can monitor our rate dynamically but it's hard to aggregate that info when we're both online to see the total bandwidth we're pushing. I've watched her sessions as well as monitoring mine and she was by no means in constant saturation. I was surprised at the constant "chatter" Skype puts on the line even with no ongoing conversations. I suspect some congestion at the DSLAM might be in play here as well. We'll see how it all shakes out in the end. I'd certainly like to get the bump to 5Mbps if it's doable and think that might just buy us a bit more life until we finally have to cave to Fios.

    I upgraded to IOS 7 just a few hours before my Iphone 5 screen froze and I cannot make changes -  I have a Connection Timeout Error with Connection to this app has timed out.  With Ok in blue.  The screen doesn't respond,  I can turn off the phone, tap OK or do anthing.  Any advice on how I can reset or fix?

    Check for any anti-virus or anti-spyware software you might have. Temporarily disable that to continue. Normally this is what will cause a timeout. I assume you have a good Internet connection?

  • Timeout for connect

    Hi there!
    I've got troubles how I can define a timeout for CreateConnect methods.
    I made a search, and found that OCCI itself doesn't support such timeout.
    I tried some parameters in sqlnet.ora
    such as: names.initial_retry_timeout, SQLNET.INBOUND_CONNECT_TIMEOUT and names.connect_timeout=3, but that didnt help at all.
    Does anybody know, how I can set timeout for database connect?
    Thanks,
    Amdras

    Hello Cipa,
    I have set this variable, but when connecting via sqlplus this process is using 100%CPU and I am not able to connect to database to start it.
    When starting sqlplus with strace it seems that there is loop in the poll function. Do you have any idea what the problem might be? Oracle version is 10.2.0.1.0
    Thanks for any help.
    Martin

  • AD MA Large Group (9000+ users) export failing due to connectivity timeout:: cd-connectivity-error

    I am currently implementing FIM 2010 in a test environemnt. I have MAs connected to the FIM Portal, an Oracle view, AD, and eDirectory 8.8SP6. All agents are working fine, users attribute flow is working great to all connected systems and groups are flowing
    into the MV without issue. I have a few criteria-based groups in the FIM portal that I am synchronizing to AD. All but one of those groups is synchronizing correctly. The failing group contains by far the most members of any group I've attempted to export
    so far, numbering around 9000 members. The only error I receive on an export run on the AD MA is "cd-connectivity-error" for the group object itself and the agent shows a run status of "dropped-connection." Event Viewer simply shows:
    The management agent "Test Active Directory MA" failed on run profile "Export" because of connectivity issues.
    Additional Information
    Discovery Errors : "0"
    Synchronization Errors : "0"
    Metaverse Retry Errors : "0"
    Export Errors : "1"
    Warnings : "0"
    User Action
    View the management agent run history for details.
    While 9000 members in a group is not insubstantial I can't help but feel like this should work. Are there configuration changes I need to make to AD in order to allow a longer timeout on the connection itself? I have tried increasing the timeout on the export
    run profile without success. Any guidance would be greatly appreciated.
    ~Jeff

    @Evgeniy Oddly enough, that is exactly the timeout change I made - 300 seconds. I am currently populating the group throung the FIM Portal. It's a criteria-based group. Basically I am taking every employee status type (we have ~12 of them) and I am creating
    sub-groups for each. The largest one of these is the one I'm timing out on. The second largest one has ~2500 members and functions as expected. If I need to change this to provision with .dll code I certainly can - I was just hoping to provide some transparency
    for our support staff and my fellow admins on these groups.
    @Carol Good idea. I will do just that. I have 2 DC's isolated in a site with an exorbitantly high site link cost specifically to service our LDAP clients and other back end services. Those 2 DC's also happen to host the majority of our FSMO roles here as
    well. I'll hardocde the link to one of those DC's and report back.
    As a secondary question, would it be better perhaps if I simply used set transitions on the user accounts to individually add them to these groups? I don't plan on using employee status for any other functions beyond this one so it seems like it may be more
    complicated to go that route but it may also be more stable.
    Thanks for all the great replies! I'll keep you posted.

  • Idle Timeout and "Connection reset by peer"

    Is there a connection between the Idle Timeout Setting and getting the "Connection reset by peer error". If I increase the  Idle Timeout value am I less likely to get the "Connection reset by peer " issue. It is currently set to 30 seconds
    We are printing over a WAN and regularly get this error on a hp LaserJet 4250n
    Also what is the difference between Idle Timeout and I-O timeout ?

    Interesting, I am going to do some research into this tomorrow, as this is not a feature that I work with much. I will get back in touch with you once I have more information so we can test different settings to see if we are able to resolve the issue.

  • IP timeout when connecting to tomcat

    I have tomcat 5.5 running and the sample servlet is running on it just fine when i connect to localhost. However, when I try to run it by connecting to my ip I get a timeout while trying to connect. Am I missing some setup or can Tomcat not be run to the outside?

    In the server.xml you need to configure the Host element to listen on your IP address. The easiest way of doing this is opening up server.xml and replacing all instances of "localhost" with your IP address.
    Of course Tomcat can be opened up for the outside world, what would be the use otherwise?

  • Problems with ethernetconnection! "Timeouts" of connection.

    Hi everyone,
    since the Mavericks-Update I got some problems with my Internet-Connection(LAN):
    1. Often the websites are not loaded. There comes no error-page or something else, its just a white page and I can see the Browser is loading but nothing happens. After refreshing the page, the page often loads correctly.
    2. Connection to messengers in the browser get lost. I open Facebook or Google+  and often the connection to the chatsystem gets lost after a few seconds/minutes.
    3. YouTube videos do not load completely. The loading bar stops often after a while!
    The problem comes up only on my ethernet connection and on every browser (Safari, Chrome, Firefox).
    ping of google.com -> lost no packages! -> Internetconnection is stabile.
    Other Notebooks are running without problems in the same network. Who can help?

    Hi Andreas,
    Thanks for visiting Apple Support Communities.
    The advice in this article may help with resolving the behavior you are seeing on your MacBook Pro:

  • ITunes timeouts when connecting to remote speakers?

    When trying to connect to a remote set of speakers (Airport Express/Airtunes), iTunes times out. The set of speakers shows in the menu, iTunes attempts to connect for some time, and then "gives up" - there is no error message. Any suggestions?
    iTunes 7.0.2, Airport Express firmware 6.3.
    Thanks.

    At times, instead of the time out, I get the following error message:
    The remote speaker "Test" is not compatible with this version of iTunes
    This happens even though iTunes and the Airport Express are up to the latest versions, respectively.
    Thanks.
