I did as per above, then did a reboot on my Debian laptop and ping from my desktop in wifi local network: # ping -c 2 www.google.com PING www.l.google.com (209.85.175.147): 56 data bytes --- www.l.google.com ping statistics --- 2 packets transmitted, 0 packets received, 100% packet loss It seems that the DNS works, but still could not get through the Internet via my laptop. The laptop does not formward packges to ppp0, something seems still missing in my loptop? If I plug an Ethernet port from an ADSL modem to the wifi router, that works. So, Iit seems to me that the wifi local network setting is fine, the problem of setting is still in the debian laptop. Please see following informaiton of my laptop status: $ /sbin/route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 139.134.108.242 * 255.255.255.255 UH 0 0 0 ppp0 192.168.5.0 * 255.255.255.0 U 0 0 0 eth1 default * 0.0.0.0 U 0 0 0 ppp0 $ /sbin/ifconfig eth1 Link encap:Ethernet HWaddr 00:20:E0:64:6E:0A inet addr:192.168.5.1 Bcast:192.168.5.255 Mask:255.255.255.0 inet6 addr: fe80::220:e0ff:fe64:6e0a/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:12 errors:0 dropped:0 overruns:0 frame:0 TX packets:12 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:1110 (1.0 KiB) TX bytes:1040 (1.0 KiB) ppp0 Link encap:Point-to-Point Protocol inet addr:144.139.45.157 P-t-P:139.134.108.242 Mask:255.255.255.255 UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1500 Metric:1 RX packets:3872 errors:0 dropped:0 overruns:0 frame:0 TX packets:3609 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:3 RX bytes:1058759 (1.0 MiB) TX bytes:460017 (449.2 KiB) Is there any debug messages can see on the debian laptop when I ping from wifi local network? There was noting shown from dmesg from the laptop when I ping from the wifi local network. Thanks all responses. Jim -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
