Why is my router attempting UDP stealth connections?

This firewall log entry shows my Linksys router attempting a stealth connection via UDP to my local computer.
I've never seen such a thing.
Any thoughts on this?
+Jul 9 20:42:48 mycomputer Firewall[39]: Stealth Mode connection attempt to UDP 192.168.1.140:64501 from 192.168.1.1:53+

UDP port 53 is normally DNS.
Ignore the "stealth mode" bits - as I understand it (but I would be interested in any correction), stealth mode properly means that a device is set up to ignore ping requests. There is no such thing as a "stealth mode connection".
Indeed, properly there is no such thing as a UDP connection either - UDP is a connectionless protocol. A device receives a UDP request and may send a UDP response.

  • Odd stealth connections

    Normally when I receive a a large amount of unsolicited connections I contact the server admin by email and inform them of what is going on. It this case however the whois look up is quite unhelpful.
    I just tried to contact ibbs through their contact web page:
    http://www.ibbs.com/contact
    Can someone help explain why I would be getting so many connection attempts?
    Thank you.
    These connection attempts have been going on for over a week. Below is a small example of what is in my appfirewall.log:

    They're DNS connections and they're very likely lookups of some site that has ibbs.com as their name server.
    These connections are harmless - what they mean is that a DNS response came in when there was no one listening for the response, often because Safari has already acted on an answer or you have since moved on to another page while surfing.

    Why do I continue to have difficulty connecting to WiFi from my iPhone5? It rarely even picks up signals from networks when my other apple products work.

    Hey CEW724,
    Thanks for the question. I understand you are experiencing issues with Wi-Fi connectivity on your iPhone 5. The following resource may help to resolve your issue:
    iOS: Troubleshooting Wi-Fi networks and connections
    http://support.apple.com/kb/TS1398
    1. Be sure you're in range of your Wi-Fi router (access point).
    2. Tap Settings > Wi-Fi and turn Wi-Fi off and on. If your W-Fi setting is dimmed,follow these steps.
    3. Confirm that your Wi-Fi router and cable or DSL modem are connected to power, turned on, and connected to the Internet. If not, refer to your network administrator or Internet service provider (ISP) for assistance.
    4. Restart your iOS device.
    5. Tap Settings > Wi-Fi and locate the Wi-Fi network to which you're connected.
    6. Tap  and Forget this Network.
    7. Try to connect to your desired Wi-Fi network.

  • N82 attempts constant wifi connection

    My N82 is constantly attempting a wifi connection to my home router, and I don't know why. I have uninstalled every single app that uses data, and checked the settings of those I can't uninstall (as they don't appear in App Manager) to confirm that this connection is not being requested anywhere.
    WLAN scanning is set to Off. Running firmware 31.01.016 (upgraded from 20.x today but hasn't fixed this).
    It is specifically interested in my home router - if I am out of range, it fills the Log with attempts to connect to it every 2 seconds. Even when I am in range of other routers which have their details stored in the phone, it will ignore them and try and connect to my home wifi.
    The constant attempts to connect only stop in two circumstances:
    when I am in range of my home wifi router and it can successfully connect, or
    if I out of range but I explicitly request a different data connection (e.g. if I connect to browse with GPRS, or connect to a different wifi router).
    Obviously this is killing my battery life. I get about 8 hours when away from home. It's driving me crazy!
    Any bright ideas would be much appreciated.

    if you had upgraded the firmware on the AEBS to 7.6.3 that could be causing the problems. Revert back to 7.6.1 to see if that fixes the issue.

  • I have a 3rd generation iPod Touch and just did the update to IOS 5. Now I can't connect to my Netgear wifi router. My iPhone connects fine along with all of my other laptops etc. I have the router set with WPA-PSK [TKIP] security and an access list.

    I have a 3rd generation iPod Touch and just did the update to IOS 5. Now I can't connect to my Netgear wifi router. My iPhone connects fine along with all of my other laptops etc. I have the router set with WPA-PSK [TKIP] security and an access list. I've confirmed the mac address is included on that list and that the password is correct. Under choses netwrok I select the network and it just goes into a spin. I have tried removing the password and the access list settings and it still will not complete the connection to the router thus no internet access. The routers firmware is also up to date. This thing worked fine before this update and I've already tried to restore from backup. Any ideas or is the wifi nic bad in this thing with the new apple firmware update? Any fix?

    Thanks Bob, I don't know why but it all of a sudden worked a few days later. It's a mystery but at least problem solved.

  • Why does my iPad2 suddenly keep losing connection on facetime?

    Why does my iPad2 suddenly keep losing connection on FaceTime and tries to constantly reconnect?

    Does it happen anywhere that you use FaceTime or only in your home WiFi network? If it happens with your home network, have you tried power cycling your router? Unplug it for about 30 seconds and then plug it back in.
    Turn WiFi off and on in the settings. Reset the network settings.
    Have you tried any troubleshooting steps at all?

    hmm, well I would say that raises the possibility of an issue with your ipad, and lessens one with your router.

  • Why does my router disconnect every time I sleep the computer? Why did this only start to happen recently?

    Why does my router disconnect every time I sleep the computer? Why did this only start to happen recently?

    Actually it does with Ethernet too: http://support.apple.com/kb/HT2412?viewlocale=en_US&locale=en_US
    What happens when the Mac goes to sleep (not just into idle mode or display sleep)?
    On all Macs:
    The microprocessor goes into a low-power mode
    Video output is turned off, and a connected display may turn off or enter its own idle state
    Apple-supplied hard disks spin down; third-party hard disks may spin down
    On portable Macs:
    The Ethernet port turns off, if applicable (see note below)
    Expansion card slots turn off
    The built-in modem, if present, turns off (see note below)
    An AirPort card, if present, turns off (see note below)
    The USB ports only responds to the power key on an external keyboard (see below)
    The optical media drive, if present, spins down
    Audio input and output turns off
    Keyboard illumination, if a feature of your portable computer, turns off
    But see the note about selecting, "Wake For Network Access" in Energy Saver preferences.
    Note: Portable computers have no network connectivity when in sleep mode, but can wake if the Energy Saver option "Wake for network access" is enabled. If you wish to use file sharing or don't want to interrupt your Internet connection, you should not manually put the computer to sleep, and you should drag the "Computer sleep" slider to Never.

  • Why does my iBookPro drop its WiFi connection so often?

    My question: why does my iBookPro drop it WiFi connection so often, and what can I do to prevent it (or at least extend the duration of active connection)?
    I have an iBookPro running OSX 10.9.5, with a 2.4 GHz Intel Core i5 processor and 8 GB 1600 MHz DDR3 RAM.  I think my iBookPro is about 3 or 4 years old.
    What seems to happen is that I will use my iBookPro accessing mail & websites for a few minutes, and then when I try to send an e-mail, mail puts up a message that it cannot send mail with the selected server, so I need to either try a different server or try later.  Meanwhile I notice that the WiFi signal indicator shows full service, but when I run diagnostics it shows that the internet is not connected.  Opening the WiFi icon in the top menu bar shows that it is looking for Networks.  After an indeterminate time it finds the network I have had highlighted and logged into (my WiFi -5G router) since I opened my iBook when I arrived at my office.
    I often find I have to turn WiFi off, then back on, to get connection with the internet. 
    What's going on, and what am I missing?

    Hello jBookProAm, 
    If you are having issues with your MacBook Pro with maintaining a Wi-Fi connection, then take a look at the articles below to get it sorted out. The first article will talk about using Wireless Diagnostics, which you have already done, but also you look at the additional troubleshooting within the article for assistance. You may want to also create a new location as another troubleshooting option and those steps are in the second article.

  • Comcast just replaced my cable modem/wireless router.  All devices connect properly except my iPhone 4.  It shows itself to be connected to the network, but it does not load any web page.  Resetting the iPhone does not solve the problem.  Any suggestions?

    Thank you for your response.
    I had rebooted the router (several times, actually), to no avail.
    I do not know the answer to whether MAC filtering is enabled on the router.  Have tried to find info about that, but unsuccessfully.  Router is an Arris TG852G, supplied by Comcast.  I would be surprised if MAC filtering were the issue, since in addition to the computer, we have successfully connected several other devices to the wifi, namely an iPad, a Android phone and a Kindle Fire - all able to access internet pages through the wifi, and all without a need to add the device to a MAC address whitelist.  To add to the mystery, the Comcast tech was able to connect his iPhone 4 to my network and access web pages.  He was unable to connect my iPhone, however, after trying for some time.
    I seem to recall reading somewhere that an iPhone cannot connect to a wireless "n" router, only "b" or "g".  The Arris router is described as a n/g/b compliant router, and as noted the Comcast tech was able to connect his iPhone, so don't know why that would be the issue here.
    By the way, my iPhone does connect wirelessly to my network at home.  This difficulty is at a second home.
    Any other thoughts would be appreciated.

  • Router reboots upon wireless connection

    I have the Linksys WRT54GS wireless router with firmware version 4.71.1. Whenever I try to connect to my wireless network, or if I even try to find it with the "View Wireless Networks" window, my router resets, thus dropping connections with my other computers (wired and wireless) and the internet. Once re-connected to the other computers and the internet, I can usually connect my wireless computer. Also, all my wireless computers have no trouble connecting automatically to my network... it's just when I want to (or need to) connect manually that my router reboots. I have tried several things (too many to list) to try and stop it, however, I was just curious as to why this would happen (FYI: my router is very stable other than that, and does not drop connections at any other time). If anyone has any insight or instructions on what I could do, please give me a hand; this issue is quite annoying at times.

    try reflashing/upgrading firmware on the router, after reflashing firmware hard reset the router back to factory default settings and reconfigure it according to ISP settings... logon to router's setup page, edit the wireless security e.g. wireless channel to 11, go to advanced wireless settings and reduce beacon intrval to 50, fragmentation and RTS threshold to 2304, transmission rate to 54mbps check whether it works for you or not.

    iTunes RADIO is not working.
    “iTunes could not connect to the iTunes Store. Make sure your internet connection is active and try again.” Try as I may, as many as ten attempts, trying to connect after restart, after shutdown, nothing works. Just so …
    iTunes STORE not “connectable” with my otherwise perfectly-working internet connection, viable, up and running for all other uses.
    Simply put, firstly, I can't connect to the internet when I click on Radio.  People are quite suspicious that this is Apple incompetence or your company's famous arrogance for this commonly-suffered problem that you won't or “can’t” fix.
    Read the many web comments and you won’t be pleased with yourselves: the suspicion is that if you ruin internet radio on iTunes, Apple will somehow make more money on music downloads, etc. Bull.
    Also, thirdly, my old playlist of 20 or so internet radio stations in the Ambient category STILL PLAYS !
    Then fourth, I installed the latest available version of QuickTime Player 7.app Version 7.6.6 but it didn’t solve the problem either. I had QuickTime Player.app Version 10.2, but substituted what Apple website said was the latest, LOWER NUMBERED QuickTime Player version of 7.6.6
    Fifth, I can't connect to iTunes store no matter what I do or what user group's advice I try. So I can’t buy or download anything from iTunes. Bad for business.
    Sixth, I updated to the latest version of iTunes but this weird problem remains. All suggested Apple fixes or user group fixes are useless. Where is Apple’s famous technical competency, vaunted customer support?, and user-friendly product reputation? Get it back, please.
    Solve this problem of yours ASAP for us, your numerous disgruntled, dissatisfied customers of iTunes. You can do better, should, and really –in all fairness- must.
    ===============================================================
    NOTE:  no password for iTunes exists in my Keychain. Is this a problem?
    Apple ACCOUNT ID, and iTunes ID password, works but not to access iTunes with my healthy internet connection.
    Apple store id It works via direct internet connetion but not through iTunes.  Very strange.

    Yes, I did try to go on my settings>wifi and was waiting for any wifi signals to pick up, but nothing shows up. But on my PC I get a whole list of networks to choose from. Regarding my neighbor, I already have her password that is why I was able to get it on my PC, the problem is that the mini Ipad is not picking any signal neither can it locate me when I go to maps.
