The reason the rfkill command failed is because you used -list instead of list. The errant - was causing problems. The full command to use is

Code: Select all

rfkill list all 
To eliminate errors, the easiest thing to do is to Copy/Paste it to the command line. (The keyboard shortcut to Paste something to the terminal is Ctrl+Shift+V. The keyboard shortcut to Copy from the terminal is Ctrl+Shift+C.)

Also, when you paste output from the terminal to the forum editor, it is best to enclose it in Code tags. That is the </> button. This will make it much easier to read. For example....

Code: Select all

Re: WIFI is connected but no internet

Post by HAWR » Sun Aug 25, 2019 8:13 am

Hello ciesel 2_4,

the nmcli are good, but "nmcli AR928X wifi rescan" can't work, because AR928X is your name of the wifi card. The rescan command is for a fresh scan of accessible networks without no output. The more important information is now the SSID for your own network. Is it shown in the list above? One network is unknown (maybe it is yours, but could have a strange SSID name, so it isn't recognized well) and the most networks use channel 11. So it could be necessary to change the SSID and the channel in the configuration of your router. For a better recognition of a SSID it is more useful to have a short name without special characters such as spaces etc.

Re: WIFI is connected but no internet

In the router settings, change the insecure, outdated and troublesome "TKIP" to modern secure "AES only". This is often enough to fix connection problems.

Re: WIFI is connected but no internet

Post by chili555 » Wed Sep 04, 2019 4:44 pm

sudo sed -i 's/3/2/' /etc/Networkmanager/conf.d/*
It is supposed to be:

Code: Select all

sudo sed -i 's/3/2/'  /etc/NetworkManager/conf.d/*
That is, with a capital M in Manager. Please try again.

May we see:

Code: Select all

ping -c3 8.8.8.8
ping -c3 www.google.com
ls -al /etc/resolv.conf
Thanks.

Have you noticed that in every case, your scan results show very low signal strength? For example:

Code: Select all

wlp3s0    Scan completed :
          Cell 01 - Address: DC:08:56:16:56:01
                    Channel:11
                    Frequency:2.462 GHz (Channel 11)
                    Quality=25/70 Signal level=-85 dBm  
                    Encryption key:on
                    ESSID:"EU-WLAN"
                    Bit Rates:1 Mb/s; 2 Mb/s; 5.5 Mb/s; 11 Mb/s; 6 Mb/s
                              9 Mb/s; 12 Mb/s; 18 Mb/s
                    Bit Rates:24 Mb/s; 36 Mb/s; 48 Mb/s; 54 Mb/s
                    Mode:Master
All of the access points that you scan are very low in strength, from 20 to 30. Your network, as you see, is 25/70 which is very low.

I am sitting about 7 meters from my wireless access point, which is in a closet and I see:

Code: Select all

wlp3s0    Scan completed :
          Cell 01 - Address: xxxx
                    Channel:149
                    Frequency:5.745 GHz (Channel 149)
                    Quality=60/70  Signal level=-50 dBm  
                    Encryption key:on

                    Mode:Master
This makes me wonder if the antenna connectors are firmly snapped in place on your wireless card. Please check.
