Model: Archer C6  
Hardware Version: V2
Firmware Version: 1.3.6 Build 20200902 rel.65591(4555)

The 2.4 GHZ band stops working multiple times during the day and i have to restart the router multiple times a day to make it work. 5.0 GHZ band continues to work normally.

 

I saw someone facing a similar problem on this thread

@Sumit56 

 

Thanks for reporting the issue to the community.

 

Can I have more details then our engineers can try to investigate further?
1. How many devices are connected to the 2.4GHz network, what are they? Are all wireless devices connected to the 2.4GHz experiencing the same dropout or just some special or old clients? If the devices are still connected to the 2.4GHz network but no internet access, please confirm if the devices can still get a correct IP address from C6, what is the IP address? Can you ping the C6 gateway and internet?
2. Try to modify the wireless settings on the Archer C6 first, such as wireless channel, channel width, which would help in some cases:

3. How did you recover the connection, do you need to reboot the C6, or disable/enable the 2.4GHz wireless on the C6, or just wait, and it will reconnect automatically?

4. Please go to the Advanced>>System Tools>>System Parameter, then please disable the NAT Boost, check again if the issue persists.

Hi Kevin,

 

Please see my response below. My issue is exactly the same as mentioned in this thread https://community.tp-link.com/en/home/forum/topic/17018. I installed the beta firmware given in that thread but it still did not fix the issue. Frequency of occurrence got minimized though.

 

Can I have more details then our engineers can try to investigate further?
1. How many devices are connected to the 2.4GHz network, what are they?

[A] 2 Devices, one router that has been configured as repeater and another one is a SMART TV (android OS)

 

Are all wireless devices connected to the 2.4GHz experiencing the same dropout or just some special or old clients?

[A] All of them

 

If the devices are still connected to the 2.4GHz network but no internet access, please confirm if the devices can still get a correct IP address from C6, what is the IP address?

[A] The connection gets dropped, if i try connecting to the 2.4GHZ network manually again i am not able to. The repeater is also not able to get an IP.

 

Can you ping the C6 gateway and internet?

[A] From 5.0GHZ, yes i can. But from 2.4, No, because no device can connect to that network.


2. Try to modify the wireless settings on the Archer C6 first, such as wireless channel, channel width, which would help in some cases:
https://www.tp-link.com/support/faq/2292/

[A] Did the changes, will let you know if that works.


3. How did you recover the connection, do you need to reboot the C6, or disable/enable the 2.4GHz wireless on the C6, or just wait, and it will reconnect automatically?

[A] Reboot C6

 

4. Please go to the Advanced>>System Tools>>System Parameter, then please disable the NAT Boost, check again if the issue persists.

[A] Did the changes, will let you know if that works.

 

In either case, to me this looks like a software bug that needs to be fixed. There shouldn't be a requirement to disable certain feature for a product to work. Else how good that product/feature is?

Hi, thanks for all the details. If changing the wireless settings and disabling the NAT boost doesn't help, please kindly try this beta firmware:

@Kevin_Z 

 

Hi,

 

Did all recommended settings and also installed the beta firmware as suggested. Problem still not resolved. The route used to work seamlessly with the stock firmware, things got screwed post upgrade. Now i cannot go back to the old firmware.

 

Please help!

@Sumit56 

 

Can I have the model number of the repeater, is it a TP-Link device? What if you disable the Onemesh feature on the C6, have you tried this?

 

If possible, we hope you could test the 2.4G connection with some phones or laptops, we can then try to locate if this is the router issue or not. BTW, what is the model of the Smart TV?
