DMA2100 requires reinstallation after calving

I have 2 DMA2100s connected via radio (using D - Link DIR-655) to my Vista MPC.  Any time either 2100 is turned off via the remote control and turned back on, the 2100 loses its ability to connect to the MPC.  I have to get a new 8-digit code and go through the procedure of installation of expansion again in Media Center.  Has anyone else seen elsewhere?  Thank you.


After several days of banging your head, I found the solution to my problem and learned something draft N Wireless.  The short answer is that upgrading the firmware on my D - Link DIR-655 of 1.11 1.21 solved the constant problem of re-installation.  I can now put or either of these devices in standby and reconnect (after turning on the PC MC) without reinstalling.  But there is much more to this story, so read on if you are interested in the details.

It turns out that many draft-N devices (not all) will not connect quick N unless the encryption algorithm is AES.  This causes a dilemma interesting with the 2100 because she don't support AES if you use WPA-2 (WPA TKIP is only).  In my case, if I select WPA-2/AES. all my devices show connect 270 - 300 Mbit/s, including the 2100 s.  Sounds good, but my 2100 s will simply not function using WPA-2 without constant disconnects and dropouts.  Track of MCE network test confirms that the data rate is completely unstable (it resembles random noise).  I suspect that 2100 equipment can not handle requests for decryption of WPA-2.  So, I had to fall back to WPA/TKIP on the 2100 s, which causes some draft-N devices to refuse to connect to something else that G (54 Mbps) speeds and others to connect to 130 Mbps (router and 2100 s).  However, the lower speed is more than compensated by the fact the flow is rock solid.  I kept the DIR-655 Router but eventually RMAing several other items advertised as "draft-N" which causes the 2100 s limitations, became very overvalued G devices.  Overall, a good glance frustrating in the world of technology "bleeding edge".

  • Tecra R850-117 starts 5 minutes after calving

    My Tecra R850-117 off, it restarts automatically after 5 minutes exactly.

    This is an unwanted behavior because it drains the battery while I don't use the laptop and it could also damage the bearing drive around during the race...

    Anyone know what could cause this problem and how can I stop it? The laptop is 6 months old and I notice this behavior only in recent weeks. I have already noticed that the battery could be emptied after not using it for a few days (probably because of the same issue?), but never noticed the unwanted reboots...

    Thank you very much in advance for all the tips.



    You have disabled the wake-up options in the BIOS?
    Check it!
    The permit * wake-up options could power on the laptop, even if the power is turned off.

  • Help the ReadyNas Duo v1 - cannot connect after calving


    From powering down my Nas (2 seagate drives - don't think that I have configure RAID) for a week or so, I've been is no longer able to connect to it, or find iton my network usjng RAIDar.

    I checked the network cables and everything seems ok. I tried an instal OS, which has solved similar problems I had in the past. It did not work. I then tried to connect by joining the Nas directly to my PC (after setting the ip address and the subnet because of the default Nas PC), but it did not work. The Nas does not show unusual led flashes after appearing to start normally. The ethernet jack suggests its connected as the two lights are solid. I have connected to my router, which shows that the sin is not connected to the network/router.

    I like to keep the data on the Nas, so I have not tried a factory reset.

    Yesterday, I tried flashjng the operating system by using a usb key with the last firmware (raidar 4.1.14) image. During this process, the led showed an error code; 3 flashes, which I think is bad content on the root partition. I have since Chouf down and rebooted. Its now still not accessible, but does not display of error codes.

    Help, I don't know what else to try!

    Just follow this thread. I tried a few free options but they do not work and recovered the data, because of file storage or RAID, movie files and music have been segmented. In the end, I had success with R-Studio, a recommendation of thoughts Botts. It is not a free service, but it was friendly and quick. Thanks again.

  • DMA2100 is frozen after trying to install wireless

    I tried to connect a new DMA2100 to my VMC and now it is completely frozen, locked, hanging, etc.  The initial screen will appear and you can window around during about 5 to 10 seconds, but then the device is completely insensitive.  I was wondering if it was a bad camera, I brought another House and it's the same thing.

    Here's the background, I tried to run the installation program to use wireless initially but the DMA2100 would simply wants it "search".  I was never able to screen so I just unplugged the device, which would lead to a repetition of the same loop.  I found a thread that said having the same questions that has been set using cable and update the firmware.  I've updated to 1.1.6 and then was able to complete the configuration and use the functions of the Extender.  As a result, I restore to its factory default condition, disconnected from the power, and disconnected the cable ethernet with intentions to go wireless.

    (Remember, it's about two units) When I turned on the unit (s) back, I noticed as the default splash screen does not pop up but rather the main screen which has 'Settings' or 'SFBC '.  Nevertheless, I followed through "settings" to run the installer again and choose Wireless this time.  Once more, it froze just.  I even waited all night on a single unit.  This time, when I recycled power to the capacity of the facility, they arrived in the State where I can only window autour for literally 5-10 seconds until I can do it without more (I waited all night for that to change too).  I tried the 'soft' reset (5 seconds the reset button) and the hardware reset (holding company of discount for 10 seconds power, break of 10 seconds and 10 seconds on).  None of this changes anything.  Within 5-10 seconds, I can window autour enough in 'settings' to see that it is a "wireless" network management mode  But I did not have enough time before it crashes to change anything.  My finger on the distance from the lock time was fun the first 10 times I tried.  even when I thought that I managed to change something, it froze again.

    I can't believe there is no real way to reset this (USB port?).  Literally, these units cannot do anything now.  I'm still waiting to hear from Linksys, but I thought that I would like to probe for any input...  I am actually very happy with all of my other Linksys products, but the quality of these units is really shocking;  I guess that's why there is a fire sale on these nowadays.

    Workaround is to disconnect the antennas while the implementation. Also, be aware, that the wireless MAC address is different from the MAC address on the serial number sticker. If you use filtering of MAC address of your wireless router.

  • Adobe Flash required plugin after installation

    There are over 100,000 firefox users who cannot watch a video and you stop and use internet explore. You had thousands of questions and you answered all of us. We are all installed the 32-bit flash as you instructed; It does not work! If you cannot solve your problem we all to empty your browser in the trash.

    First, it might not even be legal for Mozilla to fix with Flash, it's a proprietary source and closed application that limits the availability of sound ' source code.

    Second, Mozilla resources are limited. Whenever they move to come with a patch for Flash would be taken away from working directly on the code of Firefox.

    Thirdly, incident reports are probably what will by Mozilla to determine the severity of a problem. Guess anecdotal wild-timates how many users is victims (raw numbers of users or the by percentage of facilities who are affected) will not impress Mozilla.

  • WiFi requires reset after sleep

    As soon as my macbook goes to sleep and I wake up, the icon indicates that it is connected to my wifi network, but there is no internet connection until I turn off wifi and then turn it on again - if I do that, it connects perfectly. I've updated to the version the most recent of El Capitan and restarted my computer several times.

    Ditto.  I wish that someone would respond to our question/problem.  I got a MBP this past Christmas and love it, but find this very annoying problem.  My iPad Air, iPhone 5 and Windows 10 laptop Lenovo have no problem to stay connected to the internet on the same wifi network, which makes me want to point the blame on my MBP, not my WiFI router or your internet provider.

  • BBM BBM requires update after update


    I updated my Blackberry Z10 yesterday in the output above. Seems a good update, but I went to use BBM and find that it did not work as well. When you start typing a message, the white options bar is placed directly above where you write so it is impossible to check if my big fingers to write the right thing! Of course, you can get around this, but it takes more time to write quick messages!

    I guess that a BB update should be coming to solve this problem and so I was wondering if someone can suggest the correct route?

    Thank you


    Hi Ed,

    What version of BBM are you using? Is - this If this is not the case, go to BlackBerry World, open BBM and see if there is an update. Also go to settings, try in cats there is an option that says: "Stock Show bars", he was taking off or on depending on the State in which it is currently, and then reopen the BBM and see if there is a change.

  • I read that AFTER installing a language pack in Windows 7, some updates must be re-installed. How do you know which?

    That is my question.  I just did a clean reinstall of windows 7 ultimate.

    Before I did the installation, I read that I should install language packs before much updates

    Because if a person installs language packs after the updates, the updates must be reinstalled.

    I tried to install the language packs first, but windows update wouldn't let me.

    So now I think that a lot of updates must be put back.

    I looked for a list or something, but found nothing.

    Can I simply rerun microsoft update?

    I have everyone here knows about it, I would be grateful for advice.

    It's a little tricky. One day that will put you in the position of being able to receive updates is KB3161608, but this one requires reinstallation after installation of the packs of languange. :/

    Since you will need it anyway, in this case again twice, here is the link:

    You will need it as a sine qua non:

    requiring him also a reinstall after installing a language pack. :/

    Windows Update won't let you even manually install until you set automatic updates 'Never find updates' and restart, if her search runs in the background.
