Not able to connect to internet over WIFI


I am having strange situation where I am not able to connect to internet using WIFI
Everything was fine untill I was using using the following package version:


But it doesn’t work on newer versions of the linux-firmware package. I just upgraded to fedora 37 and couldn’t downgrade to above package version.

Please help

Welcome Tushar to ask :fedora:

We need to know a little more about your system.
Please run lspci -nnv and send us the part that applies to your wifi adapter as preformatted text (the </> button on the tool bar).

Also send the output of inxi -Fzxx.

The number 10ec:c822:103c:85f7 from that gives the specific chipset involved.
Both the lspci and the inxi output show the rtw-8822ce driver is loaded and inxi shows device wlp2s0 is active.

What is the output of ip address show and ip route show
If we see the expected addresses there then the issue may be dns.

You can verify internet with a ping.
If ping -c 4 gives a return but ping -c 4 does not then it would appear to be a dns issue.

IP addresses are being allocated normally.

ip address show:

3: wlp2s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
    link/ether 10:6f:d9:e5:cd:bd brd ff:ff:ff:ff:ff:ff
    inet brd scope global dynamic noprefixroute wlp2s0

       valid_lft 3518sec preferred_lft 3518sec
    inet6 fe80::e307:e99c:7488:728e/64 scope link noprefixroute 
       valid_lft forever preferred_lft forever

ip route show:

default via dev wlp2s0 proto dhcp src metric 600 dev wlp2s0 proto kernel scope link src metric 600 

But ping doesn’t work even on IP address.

ping -c 4

PING ( 56(84) bytes of data.

ping -c 4

ping: Name or service not known

Can you check if you have connectivity to your local network? Run nmap -sn and post the output.

Also is your router? Usually the router is the first host in a subnet, so it should be

nmap -sn

Starting Nmap 7.93 ( ) at 2022-12-14 12:23 IST
Nmap scan report for
Host is up (0.00012s latency).
Nmap done: 256 IP addresses (1 host up) scanned in 21.39 seconds

Looks like the network configuration is broken. Do you have another device that is connected to this network so we could check its configuration (default gateway, dns…).
