Not able to connect to internet over WIFI

Ask Fedora
1

Hi,

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:

linux-firmware-20220310-130.fc36.noarch

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 8.8.8.8 gives a return but ping -c 4 google.com does not then it would appear to be a dns issue.

IP addresses are being allocated normally.

ip address show:

    link/ether 10:6f:d9:e5:cd:bd brd ff:ff:ff:ff:ff:ff

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

ip route show:

default via 192.168.228.82 dev wlp2s0 proto dhcp src 192.168.228.199 metric 600 
192.168.228.0/24 dev wlp2s0 proto kernel scope link src 192.168.228.199 metric 600

But ping doesn’t work even on IP address.

ping -c 4 8.8.8.8:

ping -c 4 google.com:

Can you check if you have connectivity to your local network? Run nmap -sn 192.168.228.0/24 and post the output.

Also is 192.168.228.82 your router? Usually the router is the first host in a subnet, so it should be 192.168.228.1.

nmap -sn 192.168.228.0/24:

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…).
