I need help setting up a <A HREF="http://www.experts-exchange.com/Networking/Linux_Networking/Q_20957382.html">wireless</A> bridge on my Fedora Core 1 <A HREF="http://www.experts-exchange.com/Networking/Linux_Networking/Q_20957382.html">server</A>. This <A HREF="http://www.experts-exchange.com/Networking/Linux_Networking/Q_20957382.html">Windows XP</A> PCs. I want to extend this network wirelessly to my Dell Centrino portable. I reconfigured the kernel with wireless and bridge support and installed a generic 8180 wireless card using ndiswrapper. I have configured it so: iwconfig wlan0 channel 1 iwconfig wlan0 mode Ad-Hoc iwconfig wlan0 essid any ifconfig wlan0 192.168.1.10 broadcast 192.168.1.255 netmask 255.255.255.0. I have copied the output from ifconfig and iwconfig below. The portable now detects its presence so the card must be working OK. I think I want a simple bridge which just sends/receives packets from eth0 to wlan0, no fancy tricks. But if I create a bridge like this: Brctl addbr br0 Brctl addif br0 etho Brctl addif br0 wla0 then it doesn’t work and the network stops. What do I need to do? (I know I need to add encryption and change the ESSi later for securit reasons Thanks in advance Andrew IFCONFIG eth0 Link encap:Ethernet HWaddr 00:04:E2:0E:02:8A inet addr:192.168.1.1 Bcast:192.168.1.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:3388 errors:0 dropped:0 overruns:0 frame:0 TX packets:3009 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:480517 (469.2 Kb) TX bytes:956396 (933.9 Kb) Interrupt:12 Base address:0xd000 eth1 Link encap:Ethernet HWaddr 00:40:F4:5F:04:1A UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:547 errors:0 dropped:0 overruns:0 frame:0 TX packets:577 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:226238 (220.9 Kb) TX bytes:67785 (66.1 Kb) Interrupt:3 Base address:0x5000 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:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) ppp0 Link encap:Point-to-Point Protocol inet addr:61.9.182.4P-t-P:61.9.128.251 Mask:255.255.255.255 UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1492 Metric:1 RX packets:483 errors:0 dropped:0 overruns:0 frame:0 TX packets:514 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:3 RX bytes:211688 (206.7 Kb) TX bytes:54418 (53.1 Kb) wlan0 Link encap:Ethernet HWaddr 00:40:F4:5E:62:D2 inet addr:192.168.1.10 Bcast:192.168.1.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) Interrupt:5 Memory:ea000000-ea0000ff IWCONFIG wlan0 IEEE 802.11b ESSID:"any" Nickname:"wire" Mode:Ad-Hoc Frequency:2.412GHz Cell: 02:E0:8E:7D:9C:80 Bit Rate=11Mb/s Tx-Power:20 dBm Sensitivity=0/3 RTS thr=2432 B Fragment thr=2432 B Encryption key:off Power Management:off Link Quality:100/100 Signal level:-95 dBm Noise level:-256 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0 </BODY> </HTML>
