Intermittent DNS with RV082 resolution errors

Hello

With router RV082 8 ports dual-wan

I have been using this router for a little over a year.  In recent weeks, I've experienced problems navigating Web sites.  I get "page not found errors.  In a few cases I have received "certificate error messages' when there was in fact no certificate error.

I have access to a second internet connection and when I use this way pages load very well.  The problem does not exist for all URLs and sometimes the same URL are OK, sometimes they are not.

My ISP has been through an ordeal with me where we connected my PC directly to the modem and there is no problem.  When I walked through the RV082, the problem returns.

After PSI confirmed that their DNS servers are working OK, I did a voltage switched off-lit and the problem seemed to fall back, but then again once today, the problem returns.

So I will try first to describe my problem in the hope that someone will recognize this and have some advice for me.  All links to articles about the problem are very good as well.

The network has had 2 changes in recent weeks.  One, the ISP assigned IP address changed, two, the servers on the network are being reconfiguration.  But this problem just go straight the RV082 as DNS server preferred.

Thank you.

Mr. WbcAlanLee,

I'm sorry that you have this problem.  I recommend under your DHCP server settings to set the DNS for your primary or as your DNS servers of the ISP or primary 8.8.8.8 and 8.8.4.4 secondary.

Another option, you may need to look into because it looks like you're balancing of load on the router is to check if the web sites you want are https?  If the router is balancing it could send packets of acknowledgement on the other WAN and is not allowing it to resolve/connect.

You may need to bind https (443) out WAN1 or WAN2 only for the real negotiations of the Protocol.

Hope this helps,

Michael D.

  • Problems of DNS with RV082 and OSX Lion

    Hello

    I have a problem with DNS resolution, using a Mac and a router RV082.

    I use the Google DNS, it manually until 8.8.8.8 and 8.8.4.4

    The simpton is that DNS resolution is slow or fails in the Mac App Store, Firefox, Safari, etc.. I once solved this in hard reseting the RV082 and get to the page were it ask a firmware and does not work until you download the firmware.

    I did this same procedure, but no longer works. Everyone knows this too?

    Thank you

    Hi oliversl1,

    Thank you for posting. Please provide additional information:

    1. What type of internet connection? (Cable, DSL, T1)
    2. No matter what Windows PC? If so, it works ok?
    3. A new hardware version 3, is the RV082? If this is not the case, do you know how old he was?

  • Satellite L850 - Intermittent crashing with BSOD

    My Satellite L850-1LK crashes with the following error message intermittently: DRIVER_IRQL_NOT_LESS_OR_EQUAL (athw8x.sys). An online search in some other forums suggested that I should update the driver for my Atheros wireless network adapter. I did - including uninstall it completely before reinstalling with the driver downloaded from Toshiba's own site.

    I always get the BSOD, so any other suggestions would be appreciated. (I'm under 64-bit Windows 8)

    Hello

    What version of driver and what version of BIOS that you use?

    I had the same problem but not with the Toshiba laptop.
    I discovered that the installed McAfee utility causes the BSOD.
    I suggest that you remove and replace with another software antivirus like Avast! or Avira antivir.
    Both are free and can be downloaded for free.

    But of course I updated the Atheros Wlan driver too!
    You must remove the driver and uninstall the driver properly package.
    This can be done in Device Manager!
    Then clean the operating system using CCleaner!
    Reactivate the wireless lan, then install the latest driver.
    Previous updates must have replaced only part of the package of driver causing the problem.

    Hello

    I have a problem with the local domain name resolution when connected via a VPN SSL using anyconnect.

    I've identified it is due to the fact that the assigned DHCP DNS is not by adding a domain suffix.

    I proved this by adding the local domain after the host name, I'm ping.

    On the the ASA5505 ASDM I ensured that the appropriate field is identified on the DNS, but this still does not work.

    Please could someone guide me in the right direction. It should be on the profile that is downloaded or a configuration that automatically adds the correct suffix when DNS queries are sent to the DNS server.

    Hi again,

    I just figured my DNS suffix name resolution problem and I thought I'd share my solution in case it helps you:

    • Connect to ASDM, select VPN remote access, expand access to the network (Client), highlight the group policies.
    • On the right, edit the group policy that you connect your remote users.
    • Screen that comes up, highlight the server on the left and then click on the small arrow to the right to display other editing options in group policy.
    • Fill in the default domain with your internal domain name (for example, mydomainname.local)
    • Click Ok to save and save config to Flash running.

    Test of reconnection to with a client AnyConnect and performing a ipconfig/all.

    For me, I can now see the suffix dns that I defined in the group policy and successfully, I can ping internal hosts by name.

    Good luck!

  • Videos with a resolution of portrait (1280 x 720) play with a black screen, audio is heard, in Windows Media Player 12 on Windows 7

    Hello

    I noticed that the video playback for videos (with a resolution of portrait, specifically 720 x 1280, appear black with audio being heard in Windows Media Player 12 (WMP 12) on Windows 7.  A Playbook has been used to capture video to the resolution of portrait.  I also noticed that if the Playbook capture resolution 1280 x 720 of the landscape, the video plays fine in WMP 12, so I know it is not a Codec problem and seems to be related to the dimensions of the video picture.

    The same portrait videos can be read normally with VLC and other video player applications.  Is this a known problem or limitation with WMP 12 on Windows 7?

    Thank you

    P.S. as an aside, Playbook captures video in MPEG-4 AVC video Codec and Audio MPEG-1 layer 2 Audio Codec format.

    My iMac 27 "has an intermittent problem with the CPU fan runs at full speed. Sometimes it happens at the time when I start it, sometimes only in my session, and sometimes only after a certain time. So does seem to be a problem of "heating".

    Second issue is with the mode 'sleep'. It may occur also at any time, at the start of the iMac, session, or after a certain time.

    If a shortcut is used while Firefox is already open the error will not occur.

  • H satellite L505-13 - problem with the resolution of games

    Hello, I have a problem with the resolution of games, I just that:
    800 x 600 and 1024 x 768
    Yet, I have the latest version of the ati driver and directx 11...

    Windows Dectet my monitor properly (plug-and-play), and my screen resolution works well for: 1366 x 768 and 800 x 600.
    on the other hand, when I start a game I have only the choice between these two resolution: 800 x 600 and 1024 x 768...

    All the games don t fit the full screen and there is always a black area on the right and left.

    Some games (crash)... and I thought it made a link with said that I have only 2 resolution.

    I have a toshiba L505 - h - 13 (PSLS9E)
    my graphics card: ati mobility radeon hd 5145 graphics card
    OS: win 7 32 bit

    I hope someone can help me find a solution
    Thanks in advance

    Hello

    I put t know what games you want to play, but generally speaking, it of also depending on the game you can use screen resolutions. For example if your game supports only 2 screen resolutions, you can only use these resolutions.

    So all you can do is update the driver DirectX and display. Then, look for an update (patch) for the game.

    Good luck! :)

  • m8120n with a resolution of Dell U2711 Max

    I bought a Dell U2711, tested the monitor on another system with success and get a maximum resolution of 2560 x 11440.  When plugged up to the HP with a Dual Link DVI cable, somehow I can't get 1600 x 1050.  When hooked up via a VGA cable I get 2048 x 1152.  I contacted Dell, reduced to HP itself (not much help from Dell if they tried).  I've updated the drivers for the monitor and the graphics card, Geforce 7350, nothing does.

    (Ah, FYI, I searched the forum, found nothing on this subject, my warranty is also up.)

    From another thread, it's because of the card ATI 6570, set up with an Nvidia GT 430 has solved the problem.  Don't know if this applies to me since for some reason any VGA got better resolution, as well as the HDMI Jack.  (Oh yes, I also tested the cables on another system, works very well it)

    Here are the specifications of your HP Pavilion Media Center m8120n desktop. According to the specifications, the computer came from the factory

    GeForce 7350LE

    1 - DVI (and VGA with included adapter)
    2 S-video (and video Composite using adapter SV-CV)
    Interface: PCI Express x 16
    Maximum resolution:
    DVI (single bond capable): 1920 x 1440 @ 60 Hz with reduced shutter
    TV (S-video or Composite video): 1024 x 768 interlaced

    As stated in the specs, DVI is a unique link with a resolution of 1920 x 1440 max. It's not affecting your monitor, but 1600 x 1050 is perhaps the best compromise between the two. Please install a new graphics capable DVI (DL) double bond to support higher screen resolutions.

  • Tecra S10: undefined screen with a resolution of 1280 x 800

    Hi all,

    I have a strange problem with the resolution of my Tecra S10.

    My system:

    * Windows Vista, later lowered to Windows XP SP3 with the last update
    * Latest Toshiba nvidia drivers

    My default resolution is 1680 x 1050 initially and the display is sharp and perfect proportional to the screen (15.4 ", 16Million color), even if the icons are quite small.

    I changed my resolution of 1280 x 800 using the steps described in the user manual. But the screen is fuzzy and ill-defined.
    According to the manual of Toshiba (Tecra S10 Satellite Pro S300) my NVidia video card supports the resolution of 1280 x 800 WXGA mode.

    How can I put mode WXGA?

    I appreciate all suggestions that solves the problem.

    Best regards
    Biagio

    Hello

    To be honest you write on this is certainly not a problem but something usual for views. The display will be sharp and perfect when you set the view to the native resolution only.
    If you choose some other low or high resolution the illustrious office will be either too big (does not fit in the display) or will be blurred.

    The same situation is on my Tecra M1. Test it on all laptops, and the situation will be the same. I'm now working on Satellite P200 with 17 inch screen. For this display's native resolution is 1440 x 900.
    When I reduce the resolution the office is always fuzzy and ill-defined.
