Hello
I've had an Archer C7 router for about a year and it worked perfectly. Suddenly, it started having problems: the system light would go on, and I could no longer connect to it via wifi or ethernet. The only way to reconnect was to turn it off and and back on.
I contacted TP Link and got a replacement. I installed it, and in 3 days the same issue started happening. I have tried updating the firmware and resetting the router to factory settings, but the problem keeps happening.
When I connect my devices directly to the internet jack on the wall, it works perfectly. I also tried connecting an older router that I had (from another brand) and it worked for several days with no issues.
I have no idea what the problem might be, and would appreciate help solving this issue.
Thank you

Just try to connect your laptop only to 2.4GHz or 5GHz network, and check if this issue happens on the both two frequencies.
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.

Just installed the V2 EU patch (ArcherC7v2_en_eu_up.zip) and so far so good. My son's Lenovo Yoga 11IKB also contains the Qualcomm Atheros QCA61x4A adapter (latest driver from lenovo: 12.0.0.278) and before the router update it would bring down the router after about 5 secs.
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.

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!
Thank you!

also problems
2017-03-14 22:44:06
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!
