When I got a BAD connection the transfer of a file stopped working and the opening of a new web page froze from the Konqueror Browser. Here is the command line commands I used to check why the internet was not working. ifconfig wlan0 wlan0 Link encap:Ethernet HWaddr 00:06:25:26:FC:40 inet addr:192.168.1.6 Bcast:192.168.1.255 Mask:255.255.255.0 UP BROADCAST MTU:1500 Metric:1 RX packets:8468 errors:0 dropped:0 overruns:0 frame:0 TX packets:9416 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:8487231 (8.0 MiB) TX bytes:1748696 (1.6 MiB) Try pinging a known web address like Hurricane Electric www.he.net or "he.net" for short. When it says uknown host, it means that the Domain Naming Service (DNS) lookup is not working for some reason. root@2[~]# ping -c 2 he.net ping: unknown host he.net root@2[~]# ping -c 2 he.net ping: unknown host he.net Check the routing table to see if it has a valid connection to a gateway. root@2[~]# route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface root@2[~]# route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface root@2[~]# ping -c 2 he.net ping: unknown host he.net Below is after I have restarted the wlan0 from the Mepis old OS Center STATUS tab. The route command shows a "default gateway connection to 192.168.1.1 the neighbors wireless access point router" root@2[~]# route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.1.0 * 255.255.255.0 U 0 0 0 wlan0 default 192.168.1.1 0.0.0.0 UG 0 0 0 wlan0 Pinging now works and verifies that the DNS lookup is working. Changing an ascii web address like "he.net" to a tcp/ip routing number like 216.218.186.2. You can ping an IP number with the command "ping -c 2 216.218.186.2" or ping the gateway router " ping -c 2 192.168.1.1 " root@2[~]# ping -c 2 he.net PING he.net (216.218.186.2): 56 data bytes 64 bytes from 216.218.186.2: icmp_seq=0 ttl=245 time=78.6 ms 64 bytes from 216.218.186.2: icmp_seq=1 ttl=245 time=76.1 ms --- he.net ping statistics --- 2 packets transmitted, 2 packets received, 0% packet loss round-trip min/avg/max = 76.1/77.3/78.6 ms root@2[~]# Check out the interface configuration to see if wlan0 has a IP number given to it from DHCP of the router at 192.168.1.1. Yes wlan0 has IP number of 192.168.1.6 This is good! root@2[~]# ifconfig lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:2780 errors:0 dropped:0 overruns:0 frame:0 TX packets:2780 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:1272329 (1.2 MiB) TX bytes:1272329 (1.2 MiB) wlan0 Link encap:Ethernet HWaddr 00:06:25:26:FC:40 inet addr:192.168.1.6 Bcast:192.168.1.255 Mask:255.255.255.0 UP BROADCAST RUNNING MTU:1500 Metric:1 RX packets:8789 errors:0 dropped:0 overruns:0 frame:0 TX packets:9940 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:8560097 (8.1 MiB) TX bytes:1807750 (1.7 MiB) root@2[~]# Check more detail of the wireless wlan0 configurartion with iwconfig command Look for a valid ESSID value.
