Which smart switch you use bruh?I have the same issue. I use a smart plug to turn the router off for 30 minutes every night.
Even then it gets sluggish over time. The solution for me is to turn it off overnight. The ipv6 refreshes and the connection works well for a few weeks.
Anyone tried this ?i also faced the same issue..
you can follow any of the below 3 methods,
login to jio router configuration.
1) change DNS to "DNS from ISP" (DNS cache causing problem).
2) search for "ip mode".. select ipv4 only (ipv6 causing page loading problems).
3) becuase of channel frequency overlap by neighbour's wifi... Restarting router will fix it.
