Hi,
What do you mean you lost the 2.4GHz network? More specific symptom will be better.
Meanwhile, what is the current wifi leds? Especially the 2.4GHz one.
Is the status of 2.4GHz normal? You can confirm it on the web interface of the router.

Besides, did you try to power cycle the router, disable and re-enable the wifi function to give it a go?
Good day.

I got the same issue, bought TP-LINK archer C4000 router few days ago, at first i was able to connect to the 2.4Ghz and set up everything. After a day, out of sudden 2.4ghz went missing, could find the SSID at all, following 5Ghz disappear too. After hard reset, only 5Ghz SSID can be seen. 2.4Ghz totally gone.

Hi,
What is the 2.4GHz light? Does it come on when the 2.4GHz network gone?
If all the devices cannot see it? What is the status of 2.4GHz once you logged into the web interface?

May I know how did you hard reset it? Holding the reset button / hole for 10s?
Besides, what is the current hardware and firmware version?
Thanks in advance. Good day.

When i logged into the web interface i saw that 2.4GHz has a orange color wifi signal in your web interface
current hardware is v2, firmware version is v1.21

Hi,
Thanks for your reply.
Can you see the 2.4GHz network name on your device at that time? If you can see it but unable to connect to it, is there any error message?
What is the current firmware? Is it 180322?
Have you tried to change some wireless settings of 2.4GHz? Like channel and channel width.
Note: You can fix channel as channel 1, 6 or 11, and change channel width to 20MHz.
Besides, have you ever hard reset the device by holding the reset button/hole for 10s? If not, please give it a go.
Any updates, just let me know.
Good day.

Hi,
May I know if all the devices cannot see the 2.4Ghz ssid at that time? What about your laptop? Try to move them closer to the main router and check whether you can detect the 2.4GHz.
Meanwhile, what is the brand and OS version of your cellphone and laptop?
Thanks in advance, and have a nice day.

All my devices cannot see 2.4Ghz ssid, it's definetly not my laptop or cellphone problem, as i tried mac os, iphone, android, all cannot. furthermore i switch back to old d-link router i am able to see 2.4Ghz. your 5Ghz is really fast, but please update your firmware to fix the 2.4Ghz, else i think i have to switch brand

Hi,
We totally understand your feeling, both of us want to sort it out.
May I know the distance between your device and the C4000?
Did you try to move it closer to the main router and fresh the wifi list? Can you see the 2.4GHz then?
Good day.
