Respected Sir / Madam,

#Help

I am using Tplink Archer C6 V3.2 router for last one month. It was going well for a month, but now I am facing a strange problem, sometimes I see the router showing no internet even though it is connected to my vivo smartphone, at first I thought it might be a problem with my ONU or local cable operator or company, but Later I saw that the problem is not from the company or the local cable operator because I had an additional router of Linksys company at home and I checked the connection with that Linksys router, and when I saw it, I understood that the problem is with Tplink Archer C6,

I checked the whole connection of my house through my other Linksys router and I found that there is no problem with my connection, the problem is only coming from the tplink c6 router.

I could not solve this problem properly even by updating the firmware of the router. Restarting the router solved the problem for a while but the problem came back again.   

Can anyone tell me what can be done about this problem? Because updating the firmware and resetting didn't solve the problem completely.
