Archer C5400 no 2.4 wifi after couple of days and channel shows as N/A

My first router after 6 months started dropping the 2.4 band. Both 5G bands stay connected.  Got a replacement.  Replacement has lasted about a year and is now doing the same thing again.  Only way I can get the 2.4 band back up and running is turning it on and off or rebooting the router.  I have 77 days left on warranty but at this point I think I'm ready to give up and buy a different brand router.  I was thinking i have too many device hookup up to the 2.4 band a total of 24 but it seems like others are having the same issues with no work around.  I have tried channel 1, 6, 11.  I have tired guest network and nope still goes out but not as much.  When i log into router the 2.4 band won't show any encryption and you can't change it.   Has anyone found a fix?  Is a new router the way to go.  PLEASE HELP.  I don't want to spend $200 plus on another router if I don't have too even though it's been 2 years with the archer.  Thanks

We would recommend first making sure the router is up to date on its Frimware.  After that a Hard reset of the router.  Lastly we would recommned enabling Smart Connect.  Once smart connect is active you will only have a single SSID for devices to connect to.  At this point we would want to see if your 2.4GHz devices are staying connected or not.  If this all fails to resolve the issue it is likely the radio is bad and a replacement will be needed again.

 

Best Regards

It is a big shame that such an expensive router didn't receive a new firmware version ever since 2017/9/12. Especially looking at all the problems with the wifi channels. Then, the maturity and quality of the replies (if any) by TP Link 'team' is the worst I have ever met. I am still having the problem that the second 5 ghz is disappearing . Or is there already a workaround about this ISSUE?

I also have this router and I have some serius issues with it!!!

5GHz signal keeps dissapearing, but the most annoying problem is Led controller error. each time it appears in log my connection to internet breaks and for most times I have to restart rouetr to get it connected. I dont know what is the problem and didnt find the solution. It is very bad policy for TP link not to have new update to this router in nearly two years. I will hold my nerves and use this for couple of weeks and will never buy anything from tp link (long time user and i recomended few dozens of their AP or routers to friends but never again)

if someone knows solution please respond or recomend some other router

thx

BYe

Firmware updates are only usually released when ther are enhancements or bugs in the software.  Some isuses may be hardware related and as such a firmware update may not be needed.  Also it could be that the version of that device has been deemed end of life.  When this happens firmware update are only made when crtitical issues are detected.  Again this is only if these issues are software related.  If your device is on the latest FW version and an channel keeps disappearing you might have defective hardware and if you are with in the warranty period a replacement can be issued.  You would want to contact support via Chat, Phone or email though so they can collect infromation about your product, verifiy warranty eligiblity and troubleshoot if nessasary.    US support can be reached here:  https://www.tp-link.com/us/support/contact-technical-support/
