wpa_supplicant does not work

I am currently using wicd, and I tried to move to wpa_supplicant. It connects to my router, but for some reason there is no internet. Please, help me to find logs of wpa_supplicant. Information stated in gentoo wiki is obsolete, wpa_supplicant doesn't have debug use flag anymore.

Here are the logs: https://pastebin.com/E2vGA8qG

sgasgar ...

the debug useflag was removed (at my request), and debugging enabled by default ... as it doesn't increase the size of the binary, and would mean that when troubleshooting, reporting bugs, or making requests for assistance, the user wouldn't need to enable it and rebuild. So, '-d', '-dd', '-ddd', and '-f file' are available without you needing to do anything.

Some Linux based wifi drivers do not behave or function the same or as well under Linux as opposed to windows due to adherence to radio signal wireless regulatory broadcast standards compliance. One example is using hostapd with 2.4 Ghz radio with some wifi chipsets the radio signal is automatically degraded if any other radio signals on a similar radio channel and frequency band are detected.

This is naturally a large annoyance if you run your own self configured Linux based wifi access points

The point being that ensuring your access point is also not responsible and optimally configured should he a high priority. If you've never considered that physical building construction affects wifi radio performance and never used wifi analyzer with a mobile phone to optimize the ap's wifi radio config you could likely have other issues to troubleshoot before solely blaming software.

I used to help sysadmin a wireless isp in the Caribbean islands that ran off a 2.4 ghz mesh network and i'm sure as much as the next person that uses wireless networking that wifi signal on 2.4 ghz has become less than reliable in the past five years.

The log from wpa_supplicant is useful but it may not be the only reason wifi is not working.

If i could make a suggestion. provide some further information regarding your wifi setup and optimize your wifi ap radio config using the youtube video above as a guide.

Include dmesg output to show the kernel boot log, lspci and lsmod as well as relevant description of your wireless AP configuration and orientation from the pc, emerge --info and which Linux kernel config your using may be beneficial information to aid with diagnostic perspective.

Lastly do use https://bpaste.net it's a much easier to read pastebin and has no ads. trying to read a dmesg log on pastebin.com is eye cancer

Dear ali3nx,

Could you please check my other post in this thread? It looks like my problem has something to do with resolv.conf or so...

I don't see a dhcp client either in the rc setup or network scripts.
So I'm guessing wicd is starting a dhcp client on wpa connection and the dhcp client is dhcpcd.
I also see an ipv6 address, so the chances are that the ipv6 setup in dhcpcd finished before the ipv4 one and dhcpcd forked to the background.
wicd sees this, but as it cannot find an ipv4 address on the interface it thinks dhpcd failed and restarts things.

Some solutions.
* add `waitip 4` to /etc/dhcpcd.conf. This forces dhcpcd not to fork until an IPv4 address is finalised.
* use something other than wicd - like say dhcpcd-gtk or dhcpcd-qt.
* use something other than dhcpcd (but lets face it, no other client comes close to what dhcpcd can do).

Moved from Networking & Security to Unsupported Software. Not about Gentoo (but rather Calculate, a Gentoo derivative) so it fits better here.

Dear UberLord,

I have already added 'waitip4' and wicd works fine. The problem is with wpa_supplicant

Dear ali3nx,

wicd works perfectly, the connection is good and quick and signal is strong. The problem came out when I tried to switch from wicd to wpa_supplicant. I think if I could figure out why resolv.conf is different each time, it can lead to the solution.

wicd uses wpa_supplicant.
