2.4Ghz network stops working, but the 5Ghz network works

Model: Archer C6  
Hardware Version: V2
Firmware Version: 1.1.3 Build 20190712 rel.56946

Since I bought this Router I have connection problems with the 2.4Ghz network, it is like it is disabled by itself, but the 5Ghz network still works in perfect conditions. I have consulted and changed the device for warranty, I have updated, but the firmware has not worked, nor has the rollback either. I really don't know what to do to make it work, the only way to take it again is to restart the router 2 times a day. I have even tried to do it without a password or security, but even so the 2.4Ghz network does not work. Could you tell me if there is any update error of this model? 

 

Please help me!

Hello all, sorry to respond late.

 

Have you guys tried this beta firmware for the Archer C6(EU) V2?

https://static.tp-link.com/2020/202007/20200723/ArcherC6v2_eu-up-ver1-3-7-P1%5b20200723-rel33309%5d.zip

 

(Update on 2021-01-11)

We have released a new beta firmware for the Archer C6, if any of you experiences a disconnect issue with the 2.4G wireless, please give it a go, here is the download link:

https://community.tp-link.com/en/home/forum/topic/207232

 

If there is still an issue or issues with the latest beta, please confirm basic info as below:

1. Are all wireless devices experiencing the same dropout or just some special or old clients? When they got disconnected, is the 2.4GHz wireless network of the Archer C6 still broadcasting or the wireless network is no longer available on all other devices as well?

2. If only the 2.4G wireless is not stable, try to modify the wireless settings on the Archer C6 first, such as wireless channel, channel width, which would help in some cases:

Thanks again for your time and patience.

@r4zorxt 

 

What do you mean that it is disabled by itself? Any specific symptoms? Like:

 

Does the 2.4GHz wifi led come on?

 

Can you detect the 2.4GHz wireless network on your wireless devices? 

 

Any error message if you failed to connect to it?

 

Have you ever tried to forget the network and reconnect to it?

 

Besides, it is recommended to change some wireless settings, like wireless channel and channel width.

 

May it help and have a good day.

@Kevin_Z 

 

Yes of course, I have done all that, but it still has the same problem. Claim warranty even. The 2.4Ghz network only works a quarter of the day, then it falls. The one of 5Ghz, works stable always. Everything works fine except that situation. In mobile devices it appears as disabled or saved, as if it were not detected. On my computer it goes through UTP cable, so it doesn't detect any inconvenience.

@r4zorxt 

 

Thanks for your clarification.

 

If you have done all that, but still the same problem, I'm afraid that there is not much we can do.

 

Is it the replacement already? When and where did you buy it?

 

Good day.

I have been experiencing the same issue with this model! I always connect to 5Ghz, but my kids usually to 2.4GHz. Then about 2 weeks ago they started complaining about dropped connections.

 

Upon inspection with a wifi-analyzer app it turns out the 2.4GHz simply disappears, while the 5GHz is still working fine, only for the 2.4GHz signal to return on its own a few minutes later.

 

I had hoped to fix their problems by using the smart-connect option, so there would no longer be any difference in SSID, but they would automatically be connected to either signal. This has proven unsuccessful however.

 

My own phone is a priority device in the clients settings, so I can always access the router with the Tether app on my phone.

@Kevin_V Beautiful...same...exact...problem...out of the blue. Does anything just work anymore? I left Asus products for wonky firmwares and their "mesh" platform being 50% scam, 50% disaster and now, after 6 months of flawlessness, TP-Link decides to shut off it's 2.4GHz signal randomly? I know my equipment and nothing has changed in months...it sits behind a locked door and I live in the middle of the woods. No new appliances or devices in the mix other than a new fridge 2.5 months ago. But wait, rebooting it makes all my troubles disappear...for another 6-8 hours...wash, rinse, repeat. THIS. IS. NOT. GOOD.

@Pimbox  I have the exact same issue for maybe 9 months now. Running the latest firmware as well. Same model.

 

Per tech support, I have to ship the device back for a replacement because it is defective. I was told to use channgel 11 on the 2.4Ghz Wireless but it didn't help. I have tried channel 3, 10 and 11 over the year. 

 

I'm trying to justify if i should spent the shipping cost and get it replaced. I am really afraid the new device will have the same issue because you guys are having the same problem.

 

The 5Ghz wireless works just fine.
