Both Wifi and Wired connection not working which worked before.

I set up static IP for both wifi and ethernet.

What options do I have to resolve this issue?

  • What have you changed? What's in /etc/dhcpcd.conf? How are you setting a static address? What's the address of your router? Why do you need a static address? If you undo your changes do a regular DHCP address work? Did you note the settings for a DHCP address before attempting to set a static address? Does your router allow setting address by interface MAC addresss? Add some details to your question and folks may be able to answer it.

I'd suggest your first option is to read man dhcpcd.conf. Note in particular under the static value section the following passage from the author of dhcpcd:

For IPv4, you should use the inform ipaddress option instead of setting a static address.

If you're using IPv6 (instead of IPv4) I'll go ahead and apologize now for what I'm about to say:

I'll hazard a guess that you didn't read the man page before charging forward, perhaps following a blog post from a member of the TCC. Unless you understand how DHCP and networking in general operate, you really shouldn't start changing default settings in dhcpcd - which is your network manager.

All that said, if you'd like to edit your question to ask how to set up a static IP, you will get an edited answer here that explains how to do that. If you don't want to do that, I'd suggest that you leave dhcpcd.conf alone. Restore it to its original configuration, and I think you will find that things will work quite well.
