    agreed. frequency very high with 6200. Other instances I can kinda explain away (nvidia etc) but 2-6 times per day was too much. Oddly I had no obvious trigger or schedule - very random.

    Hello boys and girls. :)

    (Unfortunately I can not English, I'm German) This text is translated by Google. And revised by me on translation errors .....

    For two months I have been working on a solution. And?
    I think I know the cause.
    For me it is specifically about the "Intel WiFi 6300", but the problem is identical.
    Please be patient for another two days!

    I now know why so few users are affected.
    But more on that later.

    Incidentally, the real problem with me was very difficult to detect.
    I had cloned the same time with the WiFi built a system to other hardware.
    My troubleshooting was 1 1 / 2 months in the same direction "SystemSID for two systems on the same network.
    However, even after SID change, and even on fresh install Windows 7, the problem continues.
    A defect in my new SSD was also not excluded.
    But everything is ok except WiFi.

    I discovered this thread only a week ago.
    Just as the Intel thread, see here.
    None of all proposals to be effective. I also think Intel is not aware of the problem. It is simple but very difficult to find.

    I hope to be able to really help. Or this thread is so old that nobody has a problem? :confused:

    I just wrote about this a lot of work to spare others. (New installation, or return of the Wi-Fi)

    Final test run. Chance of success is 80%. The solution is definitely a compromise.
    Publication about Thursday or Friday. :rolleyes:

    I'm happy now. :)

    @GNandGS

    Thank you for your feedback! So it is fun. :) (You are so far the only one interested.)
    If I let my German text translated 1 to 1 of Google, is coming out just bull. I always have to "words" exchanged or replaced. :eek:
    Often even help parentheses or quotation marks. So do not wonder about it! This text took me 30 minutes of my life. :eek:

    There are still two long-time tests under different preconditions necessary.
    Chance of success is now at 90%. Moreover, the benefits remain more "WiFi 6300" received than I thought.
    Incidentally, I also think the 5300 is WiFi affected by the problem. Unfortunately I have no 5300 for testing.
    For the 5100 I can probably make a statement later. (next week)
    My test cards are:
    3x "WiFi Ultimate 6300", "1x WiFi 5100", 3x "WiFi 4965 AGN with three antennas," 1x "Wifi 3945" and 1x"Fritz USB Stick N '

    Is tested on laptops of this type:
    3x "HP Pavilion HDX Win7x64 and Vistax32"(Dual boot), 1x "Toshiba Portege A600 Win7x32 and Vistax32"(Dual boot)
    2x "Gericom MEx32" 1x "Medion Win7x32"

    Is tested on Router of this type: 1x "FRITZ!Box Fon WLAN 7270 v2 (UI)"

    I publish only when I'm 100% sure. It remains for Thursday and Friday this week. Sorry!! ;)

    Glad us lurkers can benefit -- I appreciate your assumptions, but as they say about assumptions. I've long since sold off my intel card and in fact the computer that it was used in.

    I was simply coming over here to pay a compliment to a fellow human being who saw it fit to spend some of their time trying to resolve these issues. Again it was purely to encourage his excellent work since I have no gain.

    I left this thread subscribed for all this time because I was curious there would ever be consensus that A) it was problem with the card, and B) ever would be addressed.

    Don't be an . I was offering encouragement and to not be concerned if all those who still have the card(S) choose not to post. Apparently there might be issues with or improvement to be had with cards other than 6200

    I'm sorry. The extent of my tests is really huge and still not completed.
    Unfortunately it was in the last two days results, again spoke to my theory. :(
    Thus, it is not possible for me to offer a 100% solution. On the contrary, I doubt any connection now. And if not 100%, then there is no solution. :eek:
    But one thing is clear to 100%, an emerging "Freeze" is solely in connection with the "WiFi 6300" and occurs only where it is installed.
    A system installed with "3945" or "4965" or "5100" I never did crash.
    (Under no circumstances, always stable)

    Preliminary information:
    In all my tests I am only using the 2.4 GHz band. (I never used 5.2 GHz)
    But even here I see no connection.

    1."WiFi 6300" test only to "HP Pavilion HDX9350" and "9480". (Operating System 100% identical, since "9480" is a clone of "9350")

    2.I have every available "Wifi driver" to test for a connection error - same behavior.
    ("Oldest 13.4.0.0" to the "latest 14.1.1.0" is displayed as "14.1.1.3")

    3.Each Driver removal was by deleting the old driver. Each driver installation was done only after system reboot.
    (There were no drivers to install Vista and Win7 independently, because all I had deleted)
    Better it gets.

    4.All driver settings I've tried, but could never establish a connection to the problem. That is why I describe it not in detail.

    5.All OS system error can be excluded since no problems with "WiFi 4965" in both HDX. (Never)
    Even then, when "4965 WiFi" was built "HDX" in one, and the other "HDX" with "WiFi 6300" worked.

    6."Virtual WiFi" Initially I had also suspected, but could also create a stable system without being inactivated.

    7.Before each test, I deleted the previously existing network connection and set the router back.
    Thus, here error causes are excluded.

    8.For all tests, the systems were switched on permanently. (Energy saving mode turned off)
    The same applies to the router's Internet connection and "wireless router connection" to the notebook.

    First observation:
    A freeze of "WiFi 6300" takes place only while connected to the router.
    An active "WiFi 6300" ("WiFi Laptop" turned on) without a router connection never produces a crash.
    This statement is good for debugging, but meaningless for daily operations. (Without "router connection" no wireless card required)

    Second observation:
    The freeze occurs regardless of the stress.
    I needed no large downloads. Freeze all performed in idle mode.


    Mean, 90% believed safe, theory. (Now disproved)
    But perhaps it does help someone.

    I assumed that each of the freeze problem has more than one wireless device to a router operates.
    At the same time, I assumed that each of them uses channel bonding.
    (Yes, this is just one of the advantages over an older wireless card.)

    To this end, the channel bandwidth of the WiFi drivers are provided by the 2.4 GHz "20Mhz" on "automatic".
    At the same time have the radio channel of the router to "n + g" (2.4 GHz) and "For 300 Mbit / s optimized use of radio channels" are set.

    This creates a stable 300Mbit / s connection between "WiFi 6300" and the relevant routers.
    Now is an additional router connected to a "wireless device" made in the channel bonding "2.4 GHz band" is not supported,
    it comes at the "6300 WiFi system" to freeze within minutes.
    Additional example of my connection to the same router without any "channel bonding in the 2.4 GHz band", "3945 WiFi" or "Wi-Fi 4965)
    For other users this can be any other wireless device. (Eg phone, media player, next-door neighbor who has access to the same router)
    To exclude all factors, it must have done a test.
    This was the system with "WiFi 6300" (or 6200) alone have access to the router. No other router connections!
    After 24 hours of continuous testing without a freeze, a statement can be made.

    My first recommendation for an alternative way of multiple connections to the router was switched off the router function "for 300 Mbit / s optimized use of radio channels."
    (I do not mean the WiFi driver setting)
    This was my first success in any case without any freeze error. This unfortunately only with a maximum connection speed 130Mbit / s.

    Under utilization of this knowledge, I banished all wireless devices that do not support the 2.4 GHz channel bonding.
    So I tested without 3945 and 4965th

    Further tests were performed only with a double connection to the router between "6300" and "5100".
    I switched the router to function "for 300 Mbit / s radio channels optimized use" back to active.
    Both notebooks ("HDX 6300" and "Toshiba with 5100") had stable 300Mbit / s connection.
    Test run 24 hours in idle. Do not freeze.
    My previous assumption was confirmed by yet.

    Assuming this alleged knowledge (one-sided channel bundling problem), I expected to get the Toshiba to freeze.
    To this end, I switched the driver of the "HDX 6300 in WiFi" (during connection of the two notebooks),
    the channel bandwidth to 20MHz. (was "automatically")
    result:
    Toshiba does not freeze, but the "HDX with the 6300" crash after 20 minutes. (Freeze)
    It is impossible to understand.
    Of course I made the same test again, this time however, I switched to the Toshiba 20MHz channel bandwidth.
    result:
    Again it came to the freeze on the HDX.
    The Toshiba with the "Wifi 5100" was always stable and never crashed during testing.

    The results make me mad. I find no meaningful Freeze condition.

    Now the test for Wednesday, Thursday and today. This is due to the Crown.

    Hardware and Info:
    1. "HDX9350 with 6300"
    Always stable with 300Mbit / s. Even with simultaneous use of the "Toshiba with 5100". The only requirement:
    No change in channel bonding on the fly.

    2."HDX9480 with 6300"
    Despite having the same hardware, same drivers, and exactly the same OS (only difference processor and SSD) behave differently compared to the "HDX9350".
    Behavior: "WiFi 6300" Freeze at irregular intervals.
    (Sometimes after 20 minutes, sometimes after 4 hours)
    Freeze at only active router connection. With WiFi on, without a router connection, no freeze.
    By using the original "4965 WiFi" never freeze.

    I wanted to explain this different behavior now.
    My guess: "Wifi 6300 in HDX9480" has a hardware defect.

    Test: I swapped the "WiFi cards" between "HDX9350" and "HDX9480".

    The "WiFi driver (14.1.1.3)" I have not uninstalled.
    Now I started the "HDX9480" 6300th, which presumably intact
    Result:
    Do not freeze. The system is running without interruption even now.

    Well I started the additional "HDX9350" with the suspect "WiFi 6300". The "WiFi driver (14.1.1.3)" I have not uninstalled here.
    Result:
    Do not freeze. The system is running without interruption even now.

    It is not to understand!:
    "Intel WiFi 6300" 100% original!
    MAC address on the label and the network indicator in each match.
    I'm building a card always conscientious. Installation errors are excluded.
    Is there a connection problem with the "6300"? (Contacts?)
    After the "WiFi card swap" HDX both immediately went online. (The driver I had not even uninstall)
    Both "HDX" did not notice the hardware change. (No "new devices detection" at startup)
    Here is an explanation?

    After another 24 hours I started also the "Medion notebook with 4965."
    I expected to be 100% a freeze on the HDX.
    (Remember: The "4965 WiFi" does not support the 2.4 GHz channel bonding, and brought before the HDX9350 to freeze)
    Result:
    Do not freeze. All three systems operate continuously, even now.

    This morning I started the addition "with Toshiba 5100"
    Result:
    Do not freeze. All four systems work continuously, even now. (For 8 hours)

    I am a little confused. :confused:
    Until now I have no "HDX system reboot".
    This, however, I will make soon. (After another 24 hours without a freeze)

    Conclusion:
    All my theories run into the sand. Is it the order of registration on the router?
    Has it something to do with different heat?
    If the distance between the notebook is a factor? (HDX are currently right next to each other)

    I've really invested more than enough time.
    I have all the possible test minimizes interferences.
    I've changed for each test performed only one parameter.
    There were no changes in the system test phase.
    I'm sorry, because this is not a solution!

    Sorry!
    With new insights, I'll write here.
    Perhaps a user detects a connection that has not struck me.

    This paper describes only the "Freeze changing behavior" test.
    The full extent of all of my tests can not be described.
    The only thing that is certain to 100%, using only the 6300 (I have no guess 6200, but this has the same problem), there is Freeze.
    No other system has ever had a crash.

    Finally, my main question:

    Are there users who run only a notebook (of course with "WiFi 6200 or 6300") to get a router (no other wireless devices) and a freeze?

    The answer is only interesting if Freeze is 100% of the "WiFi Connection" is due!
