My Ubuntu version is 22.04 is disconnecting from WIFI after some time

I ran this Command sudo journalctl -b 0 -u NetworkManagerand the thing I found in log is :

Jan 31 12:09:26 jitender NetworkManager[586]: <info> [1706683166.5640] dhcp4 (wlp2s0): activation: beginning transaction (timeout in 45 seconds)

Above this I have also switched the Powersaving mode to 2 and also the restarted the Network Manager Service

sudo systemctl restart NetworkManager.serviceIt still persist and I have disabled IPV6

net.ipv6.conf.all.disable_ipv6 = 1net.ipv6.conf.default.disable_ipv6 = 1net.ipv6.conf.lo.disable_ipv6 = 1
