Connection problems

CA.RIA · 05-31-2017, 03:19 AM

Hello to all memebers of the forum!

I have been using new image of Zenwalk. But I have connection problem.
I can't connect to internet.
I have been using Lenovo Y510p laptop.
Thank you.

You leave others to guess too many details! How are you connecting to the internet? (Wired ethernet, wifi, 3G/4G mobile broadband?)

Please post the relevant hardware details (even if it means running commands and capturing relevant output, saving to file, and transferring via memory stick to a computer with a working internet connection so that the details can be posted here).

Driver and firmware loaded?

Code:

/sbin/lspci -nnk|grep Network -A3

Code:

dmesg|grep firmware

Which distro are you using? Are you using NetworkManager to connect with or using some other method?

Is your wifi device visible? If not, is it hard blocked/soft blocked? The rfkill utility is needed to help with this...

Code:

/usr/sbin/rfkill list

If that checks out ok, then run to following to determine that a wireless device node exists...

Code:

/usr/sbin/iwconfig

If you are getting as far as being connected to your AP, but no internet connectivity then report back with output from

Code:

ip add

Code:

ip route

Code:

grep "name" /etc/resolv.conf

I have been using Zenwalk, latest ISO.

I can see my device, even I can connect to wifi, but Linux disconnects me immediately.

Any active device node(s) present?

Code:

/sbin/ifconfig

This will show active and inactive

Code:

/sbin/ifconfig -a

We're looking for a wireless network device node eg wlan0

Sorry, I missed this statement. Examine /var/log/wicd/wicd.log for errors.

CA.RIA · 06-01-2017, 04:17 AM

No such file or directory.

ferrari · 06-01-2017, 04:26 AM

You might have to make an effort to locate it then. I don't use wicd or zenwalk.

ferrari · 06-01-2017, 04:27 AM

Maybe start with 'man wicd'.

CA.RIA · 06-02-2017, 03:05 AM

No manual entry for wicd.

ferrari · 06-02-2017, 03:14 AM

You might try casting the net wider by posting this issue in zenwalk forums. Not sure what else to suggest here - perhaps try using NetworkManager instead.
