Hi to All,

 

 

Our TPlink Archer C80 hardware versionV1.60 

Wireless 5G not working properly anymore, its active but when you trying to connect, its keep saying "can't connect to this network"

or sometimes it can connect but the output speed is below average like 50mbps below and upload of 10mbps out of 100 mbps connection. 

 

We try already to hard reset many times and rest on wui, still the same issue. 

 

Please help. :(

 

Thanks to all

Hello @RuseLL ,

Welcome to our community.

 

Could you change the wireless settings to 5GHz? And enable the 5GHz guest network for comparison. If neither of the 5GHz networks works, please try a hard reset on the router.

For slow speed of 5GHz, please try different channels and channel widths. 

 

If suggestions above don't help, please consider contacting local support for further help.
