    I'm trying to connect to an Archer D5 AC1200 router. Below are the firmware and hardware versions.

    Firmware Version:0.9.1 0.8 v002e.0 Build 150526 Rel.63088n
    Hardware Version:Archer D5 v1 00000000

    Thanks
    You'd better propose a ticket to TP-Link support team.

    It happens on each of the frequencies individually. I typically connect to only the 5GHz network and continue to use only that network until it crashes. Typically the 2.4Ghz network continues to work and does not seem to be influenced by the 5GHz network going down. I then use the 2.4GHz network until it crashes, too (usually not very long). Then I go unplug the router and plug it back in and start over.

    I too am having the same issue with my an MSI laptop that has killer wifi card, I've tried to flash the beta firmware but it is not accepted, router details are;

    Firmware Version: 1.7.0 0.9.1 v0051.0 Build 160322 Rel.56836n
    Hardware Version: Archer D7 v1 00000002

    Is there a new Beta firmware for people on firmware 1.7?

    5-10 minutes of Google Hangouts is enough to kill the internet even with the new firmware. I'm still amazingly amazingly frustrated and underwhelmed with the whole tp-link fiasco...

    I just bought the router 2 weeks ago and was wondering why the 5g and internet connection itself kept on dropping. Thank god I googled it and it turns out that my new laptop has this exact same wifi chipset. It really is a killer I guess, kills the router. LOL. Trying the new firmware out hope it fixes it.

    Recommended to contact tplink support for more troubleshooting.

    One thing that threw me for awhile: when upgrading the firmware the router does not reboot, I waited 10 minutes with the green progress bar stuck at 100% before I logged on in another browser tab and found out the update (and presumably the reboot) had already happened. The new background is hideous but guess what, it now works and that's all that counts. Thanks tp-link for solving this!
    An update: my son's Lenovo laptop connects to the 2.4 GHz band and the connection is stable, but no connection can be made using the 5GHz band. And now my employer has provided me with a bright new Dell XPS including the infamous Killer WIFI that shows exactly the same behaviour: stable connection at 2.4 GHz, no connection at 5GHz. On both laptops the 5GHz network is listed as available but connection fails.

    Just wanted to report that I started having dropped connection/router problems similar to some other posters in this forum, which started after I purchased a Lenovo Yoga 710 with the Qualcomm Atheros QCA61x4A Wireless Network Adapter. The problems seem to have been resolved since I installed the beta firmware.

    Firmware Update Question

    How will we know when this bug fix is incorporated into the stable firmware?

  10. #70
    I have Acer Swift 3 with Qualcomm Atheros QCA61x4A. I am running the beta for 7 days already and I don't find any issues. Before with the official version I got the problem and had to reboot the router every hour. So, my question is, when this will become official firmware?
    Thank you!

    Post also problems

    Hi to all!
    I'm very glad that I have hade found this post! I also encounter to SAME problems that everyone has: when I try to connect to archer C7 v2 with my MSI GS60 6qe (Killer network wifi card) first of all the 5ghz network disappears, secondly none of the devices can connect to the 2.4ghz network. Lastly: system light is turned either on or off. The only solution is resetting the router. The problem repeats itself in a matter of seconds after reset if my notebook is turned on. Somehow it seems that our wifi works longer if I connect to 5ghz network rather than 2.4ghz one. Funny thing is that router is relatively new in our house and that it work flawlessly on stock software for some time (I don't remember stock firmware but I do have a backup of settings somewhere). It's most lightly that problems started when I installed the latest firmware: Archer_C7(EU)_V2_160616 ~3 weeks ago but at first, there weren't any such problems--at least I didn't encounter them(?). I didn't manually update drivers on my notebook with killer network but maybe windows update did it automatically somehow...

    I will let you know if and how did I manage to fix the problem. At the moment I'm studying in another city so I will troubleshoot home network at weekend.

    Best luck to all!

    After 118 days, 81 emails and many hours on the phone with technicians in SE Asia I received my XPS 13 9360 back for the second time. It now has an Intel dual-band AC8265 wireless adapter card and the Win 10 OS was cleared and re-installed.

    Works great! The Qualcom/Atheros Killer card and Win 10 combined were the problem, not TP Link.

    Thank you moderators and all who contributed.

    KK4NAG, the problem is the router. No card/OS should be able to crash a router. This is definitely a weakness in the firmware of the router. I installed the beta and so far works fine: System Up Time: 15 days 08:31:34

    Hi to everyone!
    I've only updated drivers on my notebook (one with killer network) and it seems the problem is now GONE . I've found this text on other forums :

    " Hi folks - we have just posted a new wireless driver and software suite that addresses a known issue on a small percentage of systems where the Killer Wireless module will drop the WiFi connection when passing a large amount of traffic. We have worked closely with Microsoft on this, and have identified a fix. This fix has been confirmed with several users that currently have the issue and we have posted a new software package. Please visit the link below to get the new driver:www.killernetworking.com/.../e2200-e2400-wireless
    If there are issues after using this, please feel free to contact our support through our website for assistance.
    www.killernetworking.com/.../contact "

    So this fix seem to work on my gs60 with Killer Wireless-n/a/ac 1525 Wireless Network Adapter running driver
    Driver Provider: Qualcomm Atheros Communications Inc.

    Driver Date: 12. 02. 2017
    Driver Version: 12.0.0.296
    Digital Signer: Microsoft Windows Hardware Compatibility Publisher

    and on AP tp-link archer C7 :
    Firmware Version: 3.15.1 Build 160616 Rel.44182n
    Hardware Version: Archer C7 v2 00000000

    I hope this, or any other fix works for you!

    Unfortunately, this new driver and router beta firmware do not seem to resolve the problem for me. My son was back from school with his newish Lenovo Flex 4. After he killed our TP-Link Archer C7 v3 with firmware3.15.1 Build 161101 Rel.40542n, I updated the driver for his Qualcomm Atheros QCA61x4A wireless card to the latest version from killernetworking.com, 12.0.0.296. He was running all the latest updates for Windows 10. Sometimes it would take minutes, other times it would be a few hours, but his computer would bring down our router. This is very frustrating. I don't know who is at fault, but a wireless card should not be knocking out a router.

    From similar text posted above:

    Hi folks - we have just posted a new wireless driver and software suite that addresses a known issue on a small percentage of systems where the Killer Wireless module will drop the WiFi connection when passing a large amount of traffic.

    This fix will not resolve issues related to the router misbehaving, as that is a router specific problem, however if the issue was specifically with intermittent WiFi drops related typically to heavy traffic, the above should address that. (emphasis added).

    Killer Networking is saying this is a router issue. I am at the point where I need to purchase a separate Wi-Fi adapter for my son to use when he is home. That does not seem like a real solution.
