Title: NetworkManager wireless connection issue (VL 7.1 64)
Post by: scififry on April 09, 2018, 04:18:50 pm
Hello everyone,

I'm able to connect to a wireless network using NetworkManager, but somehow the established connection does not work, i.e. I'm unable to load any websites, ping other hosts etc. even though I should have a connection. Connecting via Ethernet works fine. The computer's hostname even shows up in the router's web interface as being connected over a wireless connection and I've experienced the same problem with a different router.
This wireless card has worked with WICD (although in a different computer with VL 7.0 Gold) before; this is its lspci entry:
Code: [Select]
04:02.0 Ethernet controller: Qualcomm Atheros AR5212/AR5213 Wireless Network Adapter (rev 01)
iwconfig's output on the wireless connection:
Code: [Select]
wlan0     IEEE 802.11bg  ESSID:"(Here was the SSID)" 
          Mode:Managed  Frequency:2.427 GHz  Access Point: (Here was the router's MAC address)   
          Bit Rate=1 Mb/s   Tx-Power=20 dBm   
          Retry short limit:7   RTS thr:off   Fragment thr:off
          Power Management:off
          Link Quality=49/70  Signal level=-61 dBm 
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:6  Invalid misc:6   Missed beacon:0

And ifconfig's output on wlan0:
Code: [Select]
wlan0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet  netmask  broadcast
        ether (Here was the wireless card's MAC address)  txqueuelen 1000  (Ethernet)
        RX packets 17  bytes 3284 (3.2 KiB)
        RX errors 0  dropped 10  overruns 0  frame 0
        TX packets 6  bytes 1942 (1.8 KiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

What is the issue?
Any help would be greatly appreciated!
