[SOLVED]The network is working but... it doesn't

So I have TP-LINK TL-WN722N, it works previously, but today I have strange issue - I cannot browse any website and ping, but some apps like TeamSpeak and Steam still connect and works. I found something like this https://wiki.archlinux.org/index.php/Ne … ng_problem but it doesn't fix my problem. It works fine on Windows, all outputs seems ok... but still doesn't work

Re: [SOLVED]The network is working but... it doesn't

Just guessing but it could be these working applications use IP addresses directly and not hostnames.

Could you show us your resolv.conf

cat /etc/resolv.conf

Re: [SOLVED]The network is working but... it doesn't

Welcome to the forums.  We'd be happy to help, but as indicated above, we really need some information.  It could be a DNS issue - but that is just a wild guess in the absence of any real information.

Yeah, sorry, it's hard to post something without internet.

Then that's the problem.  By the way, I'm not sure what 93.158.134.11 is, but the failure to ping that one is because that server is down.  So the only problem is that your networking service is not properly creating DNS entries in resolve.conf.

What networking services are you using?

You could manually add a nameserver like 8.8.8.8 to your resolve.conf for a temporary workaround.  This should allow you to get "real" internet access while you dig deeper.  But you should figure out why dhcpcd or any other network service isn't properly creating entries itself.

Re: [SOLVED]The network is working but... it doesn't

Looks like I found a problem. My /etc/resolv.conf was a link to /var/run/connman/resolv.conf after connman update but I haven't this file. So I delete this and create a new /etc/resolv.conf and everything works fine now

Re: [SOLVED]The network is working but... it doesn't

I ran into the same thing the other day. Easy to fix, but it wasn't immediately obvious what created the symlink -- I don't use connman, but had kept it installed after giving it a try last year.
