• Errors when trying to compile the driver for the rtl8192su wireless adapter

  - by Tom Brito

  I have a wireless to usb adapter, and I'm having some trouble to install the drivers on Ubuntu. First of all, the readme says to use the make command, and I already got errors: $ make make[1]: Entering directory `/usr/src/linux-headers-2.6.35-22-generic' CC [M] /home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u/r8192U_core.o /home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u/r8192U_core.c: In function ‘rtl8192_usb_probe’: /home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u/r8192U_core.c:12325: error: ‘struct net_device’ has no member named ‘open’ /home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u/r8192U_core.c:12326: error: ‘struct net_device’ has no member named ‘stop’ /home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u/r8192U_core.c:12327: error: ‘struct net_device’ has no member named ‘tx_timeout’ /home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u/r8192U_core.c:12328: error: ‘struct net_device’ has no member named ‘do_ioctl’ /home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u/r8192U_core.c:12329: error: ‘struct net_device’ has no member named ‘set_multicast_list’ /home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u/r8192U_core.c:12330: error: ‘struct net_device’ has no member named ‘set_mac_address’ /home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u/r8192U_core.c:12331: error: ‘struct net_device’ has no member named ‘get_stats’ /home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u/r8192U_core.c:12332: error: ‘struct net_device’ has no member named ‘hard_start_xmit’ make[2]: *** [/home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u/r8192U_core.o] Error 1 make[1]: *** [_module_/home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/HAL/rtl8192u] Error 2 make[1]: Leaving directory `/usr/src/linux-headers-2.6.35-22-generic' make: *** [all] Error 2 /home/wellington/Desktop/rtl8192su_linux_2.4_2.6.0003.0301.2010/ is the path where I copied the drivers on my computer.

• Upgraded to 12.04 now wifi doesn't work

  My laptop's wifi stopped working when I upgraded to Ubuntu 12.04 (wired works). I just reinstalled 12.04 over my old 12.04 on which wifi didn't work either in an attempt to restore any settings I may have accidentally changed, but it still doesn't work.

• Drivers for Atheros AR928X?

  - by Pato7

  I am new in Ubuntu and I had a big trouble with wifi. My ubuntu 12.10 doesn't detect my wifi card and I can't toggle the "activate wireless" option on the tasks bar (it is grey). I searched for drivers to make it work, but nothing worked for me. Can anyone give me a hand?

• OpenVPN not connecting

  - by LandArch

  There have been a number of post similar to this, but none seem to satisfy my need. Plus I am a Ubuntu newbie. I followed this tutorial to completely set up OpenVPN on Ubuntu 12.04 server. Here is my server.conf file ################################################# # Sample OpenVPN 2.0 config file for # # multi-client server. # # # # This file is for the server side # # of a many-clients <-> one-server # # OpenVPN configuration. # # # # OpenVPN also supports # # single-machine <-> single-machine # # configurations (See the Examples page # # on the web site for more info). # # # # This config should work on Windows # # or Linux/BSD systems.

• Several IPs for my VPS

  - by Serafim

  I bought vps on santrex.net but can't receive any reply from support. My Problem: I have 5 ip but it pings only 1!!! I can't setup DNS because I need 2 ip minimum .

• eth0:0 is configured but not listed in ifconfig output

  Hello. I have the following problem: My server was given two IPs from [b]different[/b] subnets. Now I am trying to configure the system to work properly. I have created [root@server ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0 # Intel Corporation 80003ES2LAN Gigabit Ethernet Controller (Copper) HWADDR=00:30:48:DA:B1:0E DEVICE=eth0 BOOTPROTO=none BROADCAST=79.174.69.255 IPADDR=79.174.69.241 NETMASK=255.255.254.0 NETWORK=79.174.68.0 ONBOOT=yes GATEWAY=79.174.68.1 TYPE=Ethernet [root@server ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0:0 # Intel Corporation 80003ES2LAN Gigabit Ethernet Controller (Copper) HWADDR=00:30:48:DA:B1:0E DEVICE=eth0 BOOTPROTO=none BROADCAST=79.174.69.255 IPADDR=79.174.71.74 NETMASK=255.255.255.0 NETWORK=79.174.71.1 ONBOOT=yes GATEWAY=79.174.71.1 TYPE=Ethernet But both after "service network restart" and after "reboot" [root@server ~]# ifconfig eth0 Link encap:Ethernet HWaddr 00:30:48:DA:B1:0E inet addr:79.174.71.74 Bcast:79.174.71.255 Mask:255.255.255.0 inet6 addr: fe80::230:48ff:feda:b10e/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:910284 errors:0 dropped:0 overruns:0 frame:0 TX packets:2924 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:100 RX bytes:257964879 (246.0 MiB) TX bytes:232450 (227.0 KiB) Memory:df220000-df240000 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:27 errors:0 dropped:0 overruns:0 frame:0 TX packets:27 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:6976 (6.8 KiB) TX bytes:6976 (6.8 KiB) Device eth0:0 is not shown as active.

Also it is strange, that IP address assigned to eth0:0 in config file is used by eth0. /var/log/messages shows nothing about network configuration errors on either eth0 or eth0:0. system-config-network seem to understand all settings correctly and resaves them ok also. "ifup eth0:0" executes ok, but ifconfig afterwards shows no eth0:0 device after that. What did I do wrong? May be the problem is that IPs are from different subnets?

• Force netsh/arp binding multicast IP addres with specific MAC address

  - by Olivier

  I would like to setup an binding from an IP address to a MAC address using netsh. Goal is to bond an IP address which is a multicast address (224.224.x.y) to a given MAC address (which is NOT the calculated one from the multicast IP address : 01:00:5e:X:Y:Z It used to work with Windows XP (was it a bug that used to be "perfect" for my needs?), but Windows 7/8/8.1 forces the MAC address to the calculated one instead of letting me put what I want! (http://nettools.aqwnet.com/ipmaccalc/ipmaccalc.php shows MAC address calculation for multicast IP address) Thus I'm doing the following. Listing existing mappings: netsh.exe interface ip show neighbors "Ethernet" Interface 12 : Ethernet Internet address Physical address Type 224.0.0.22 01-00-5e-XX-YY-ZZ static Then adding my interface mapping manually: netsh.exe interface ip add neighbors "Ethernet" "224.xxx.yyy.zzz" "00-80-EE-UU-VV-WW" Finally, listing again my mappings: netsh.exe interface ip show neighbors "Ethernet" Interface 12 : Ethernet Internet address Physical address Type 224.0.0.22 01-00-5e-XX-YY-ZZ static **224.xxx.yyy.zzz 01-00-5e-UU-VV-WW static** As you can see, the MAC Address of the second entry (the one I just made) has been dynamically replaced by the calculated MAC Address corresponding to my IP Address... Calculation is done as follow (and displayed in hexa): UU=(xxx-128) VV=yyy WW=zzz But I don't want that behavior. My IP address and MAC address cannot be changed, and I must associate them accurately. Does anybody know how to disable MAC address substitution/calculation in netsh? Thanks, Olivier.

• routing specific IP to ppp0 tunnel

  - by gompertz

  Hi All, I feel I've struggled with this long enough and need some help. I have a pptp tunnel and am trying to route destination traffic from 208.85.40.20 to the pptp tunnel (ppp0). (Keen observers may recognize the ip as being that of pandora.com). I am doing all this configuration on a router... and I know it's not working successfully as traceroute yields nothing but astericks. I've pasted relevant outputs below: (with some "security" editing to the addresses) root@OpenWrt:~# ifconfig br0 Link encap:Ethernet HWaddr 00:1A:92:BC:XX:XX 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:28185 errors:0 dropped:0 overruns:0 frame:0 TX packets:24936 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:4894242 (4.6 MiB) TX bytes:5941902 (5.6 MiB) eth0 Link encap:Ethernet HWaddr 00:1A:92:BC:XX:XX UP BROADCAST RUNNING PROMISC MULTICAST MTU:1500 Metric:1 RX packets:51829 errors:0 dropped:0 overruns:0 frame:0 TX packets:56824 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:11490288 (10.9 MiB) TX bytes:11857913 (11.3 MiB) Interrupt:4 eth2 Link encap:Ethernet HWaddr 00:1A:92:BC:XX:XX UP BROADCAST RUNNING ALLMULTI MULTICAST MTU:1500 Metric:1 RX packets:4 errors:0 dropped:0 overruns:0 frame:15426 TX packets:9529 errors:21 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:423 (423.0 B) TX bytes:596036 (582.0 KiB) Interrupt:2 Base address:0x2000 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:30 errors:0 dropped:0 overruns:0 frame:0 TX packets:30 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:2300 (2.2 KiB) TX bytes:2300 (2.2 KiB) ppp0 Link encap:Point-Point Protocol inet addr:68.68.39.250 P-t-P:172.16.20.1 Mask:255.255.255.255 UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1400 Metric:1 RX packets:165 errors:2 dropped:0 overruns:0 frame:0 TX packets:68 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:3 RX bytes:7006 (6.8 KiB) TX bytes:3462 (3.3 KiB) vlan0 Link encap:Ethernet HWaddr 00:1A:92:BC:XX:XX UP BROADCAST RUNNING ALLMULTI MULTICAST MTU:1500 Metric:1 RX packets:28182 errors:0 dropped:0 overruns:0 frame:0 TX packets:33813 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:5006544 (4.7 MiB) TX bytes:6609774 (6.3 MiB) vlan1 Link encap:Ethernet HWaddr 00:1A:92:BC:XX:XX inet addr:173.183.111.3 Bcast:173.183.111.255 Mask:255.255.224.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:23653 errors:0 dropped:0 overruns:0 frame:0 TX packets:23012 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:5522012 (5.2 MiB) TX bytes:4982944 (4.7 MiB) wds0.4915 Link encap:Ethernet HWaddr 00:1A:92:BC:XX:XX 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) wds0.4915 Link encap:Ethernet HWaddr 00:1A:92:BC:XX:XX 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) root@OpenWrt:~# cat /etc/ppp/ip-up iptables -A FORWARD -t filter -i br0 -m state --state NEW,ESTABLISHED,RELATED -j ACCEPT iptables -A FORWARD -t filter -i ppp0 -m state --state ESTABLISHED,RELATED -j ACCEPT iptables -t nat -A POSTROUTING -o ppp0 -s 192.168.1.1/24 -d 0/0 -j MASQUERADE iptables -A forwarding_rule -o ppp0 -j ACCEPT iptables -A forwarding_rule -i ppp0 -j ACCEPT iptables -t nat -A postrouting_rule -o ppp0 -j MASQUERADE root@OpenWrt:~# route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 172.16.20.1 * 255.255.255.255 UH 0 0 0 ppp0 208.85.40.20 * 255.255.255.255 UH 0 0 0 ppp0 192.168.1.0 * 255.255.255.0 U 0 0 0 br0 173.183.192.0 * 255.255.224.0 U 0 0 0 vlan1 default d173-183-192-1. 0.0.0.0 UG 0 0 0 vlan1 default 192.168.1.1 0.0.0.0 UG 0 0 0 br0 Any advice is greatly appreciated, I'm not too great with network but am pretty astute at learning ;-)

• Mac OS X: pushing all traffic through a VMWare VM [closed]

  I want to set up an Astaro (Sophos) UTM in a Virtual Machine. The Setup should be at the end the following: Cable Modem (one IP adress) | [Ethernet] Sophos UTM (running as VM [VMWare Fusion 5] on the MacMini) | [WIFI] Airport Express v2 (for sharing Local Network to wireless and wired clients) 1)| [WIFI] 2)| [Ethernet over Thunderbolt Ethernet Adapter]* Clients MacMini (Local File Server) *To have the Mini also protected behind the UTM So the setup process for the UTM works fine, but then the problems start: I just have one external IP (from my cable modem provider)== So if I put the VM in briged mode my Internet connection drops, because the MacMini also has its IP adress. If I put the VM to NAT mode the Mini itself is not protected by the UTM So: is there a way to hide the en0 interface(Ethernet) and the en1 interface (Wifi) from the MacMini, so that they not even appear in System Preferences Network section but are available to the VM? That way the Mini must connect to the en2 interface (Thunderbolt adapter) to make any Internet/LAN connection and I just use the given single IP from the Cable Modem. Thaks for any suggestions...

• The RTL8111/8168B NIC under Linux and the r8168 driver

  - by nik

  So I've got one of the infamous R8168 Realtek ethernet NIC, which have some problems under Linux. After some research, I found out I had to use the r8168 driver for this card (and not the r8169 which still loads when nothing else is available), which I did. So now everything works fine... Sort of. My download and upload rates are more than halved compared to what I should get. When I test (with eg. speedtest) I get something like 20M (often 15M) in download and 30M in upload, but if I test under Windows (everything is otherwise identical: same ethernet cable, same connection, at the same time of the day (well 5 min apart)...), I get 50M upload/download (which is what I expect). Where can it come from? Here's some info: ~ # lspci [...] 06:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.

• Public static ip for vagrant box

  - by Numbata

  I have server (Debian Squeeze) with 1 ethernet card and 2 public static IPs (188.120.245.4 and 188.120.244.5). What I want: Setup virtual box (Ubuntu) with access via static IP (188.120.244.5). What I was trying: config.vm.forward_port - good idea: setup interface "eth1:1" with 188.120.244.5 on host-machine, and add to Vagrant file "config.vm.forward_port = hmm..?" config.vm.network :hostonly, "188.120.244.5" - not working. Was created new interface on host-machine with ip "188.120.244.1". Of course 188.120.244.1 IP isn't mine and I can't access my server via this IP. config.vm.network :bridged - I'm confused how this works :) What I have now: Not working configuration. Debian-host-machine# cat Vagrantfile Vagrant::Config.run do |config| config.vm.define :gitlab do |box_config| box_config.vm.box = "ubuntu" box_config.vm.host_name = "ubuntu" box_config.vm.network :bridged box_config.vm.network :hostonly, "188.120.244.5", :auto_config => false end end Debian-host-machine# ifconfig eth1 Link encap:Ethernet HWaddr 00:15:17:69:71:bb inet addr:188.120.245.4 Bcast:188.120.247.255 Mask:255.255.248.0 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 vboxnet0 Link encap:Ethernet HWaddr 0a:00:27:00:00:00 inet addr:188.120.244.1 Bcast:188.120.246.255 Mask:255.255.255.0 Ubuntu-virtual-machine# ifconfig eth0 Link encap:Ethernet HWaddr 08:00:27:ee:8d:0c inet addr:10.0.2.15 Bcast:10.0.2.255 Mask:255.255.255.0 eth1 Link encap:Ethernet HWaddr 08:00:27:45:71:87 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 How I can access virtual box via public static IP from network?

• Intel NIC X540-T1 non-functional in Ubuntu Server 12.04

  - by Jeff Carr

  I have installed three Intel X540-T1's in servers running Ubuntu Server 12.04, but all are non-functional, no link lights, no packets sent or received, and no connection on ip4 or ip6 whether set up as dhcp or static. Also, dmesg doesn't detect cable connection or disconnection. I updated the default ixgbe driver to Intel's latest version (3.11.33) with no change. The ethernet controller is being reported as X540-AT2 (which might be a problem that I can't figure out how to fix), but the subsystem is X540-T1 so I believe that might be intended. Does anyone have any experience with this that could assist? ifconfig eth2 eth2 Link encap:Ethernet HWaddr a0:36:9f:14:5f:ea inet addr:192.168.101.1 Bcast:192.168.101.255 Mask:255.255.255.0 UP BROADCAST MULTICAST MTU:1500 Metric:1<br> 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) ethtool -i eth2 driver: ixgbe version: 3.11.33 firmware-version: 0x8000037c bus-info: 0000:08:00.0 supports-statistics: yes supports-test: yes supports-eeprom-access: yes supports-register-dump: yes lspci -vvnns 08:00.0 08:00.0 Ethernet controller [0200]: Intel Corporation Ethernet Controller 10 Gigabit X540-AT2 [8086:1528] (rev 01) Subsystem: Intel Corporation Ethernet Converged Network Adapter X540-T1 [8086:0002] Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr+ Stepping- SERR+ FastB2B- DisINTx+ Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Latency: 0, Cache Line Size: 32 bytes Interrupt: pin A routed to IRQ 16 Region 0: Memory at e8000000 (64-bit, prefetchable) [size=2M] Region 4: Memory at e8200000 (64-bit, prefetchable) [size=16K] [virtual] Expansion ROM at e8280000 [disabled] [size=512K] Capabilities: <access denied> Kernel driver in use: ixgbe Kernel modules: ixgbe

• Routing a PPTP client and VMware Server instance running on the same box

  - by servermanfail

  I have a Windows 2003 SBS box. It has 2 physical NIC's: WAN and LAN. The WAN is a public IP. The LAN is a simple 192.168.2.x subnet with Microsoft DHCP Server. Microsoft Routing and Remote Access Service is used to provide NAT to LAN. The box also runs VMware Server with a virtual machine running Windows XP. I want people to be able to VPN into the box, and connect to these virtual machines on the MSRDP port. I can VPN (PPTP) into the 2003 SBS box fine, as well as ping other machines on the LAN. I can ping the VM from a physical workstation on the LAN and vice-versa. I can ping the VPN client from the a physical workstation on the LAN and vice-versa. I can ping the VPN client from the Server console and vice-versa. I can ping the VM client from the Server console and vice-versa. But I cannot ping the VPN client from the VM and vice-versa. I was hoping to set up 2 or 3 Windows XP virtual machines on our only server, so that a couple of people can remote in to work without having to leave a physical machine on in the office. You could this attempted set up a "poor mans terminal server". On the 2003 SBS Server:- C:\Documents and Settings\Administrator>route print IPv4 Route Table =========================================================================== Interface List 0x1 ...........................

Here is my ifconfig dump: em1 Link encap:Ethernet HWaddr 00:A0:D1:ED:D0:54 inet addr:173.208.230.106 Bcast:173.208.230.111 Mask:255.255.255.248 inet6 addr: fe80::2a0:d1ff:feed:d054/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:100058 errors:0 dropped:0 overruns:0 frame:0 TX packets:18941701 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:12779711 (12.1 MiB) TX bytes:825498499 (787.2 MiB) Memory:fbde0000-fbe00000 em1:9 Link encap:Ethernet HWaddr 00:A0:D1:ED:D0:54 inet addr:173.208.230.107 Bcast:173.208.230.111 Mask:255.255.255.248 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Memory:fbde0000-fbe00000 em1:10 Link encap:Ethernet HWaddr 00:A0:D1:ED:D0:54 inet addr:173.208.230.108 Bcast:173.208.230.111 Mask:255.255.255.248 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Memory:fbde0000-fbe00000 em1:11 Link encap:Ethernet HWaddr 00:A0:D1:ED:D0:54 inet addr:173.208.230.109 Bcast:173.208.230.111 Mask:255.255.255.248 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Memory:fbde0000-fbe00000 em1:12 Link encap:Ethernet HWaddr 00:A0:D1:ED:D0:54 inet addr:173.208.230.110 Bcast:173.208.230.111 Mask:255.255.255.248 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Memory:fbde0000-fbe00000 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host 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)

• Downloads are consistently corrupt, what are the potential causes?

  - by user41755

  I am consistently experiencing corrupt downloads over TCP/IP and Ethernet on a small LAN, the downloads are coming from different sources on the Internet. WAN is comcast cable.. NIC is brand new. My theory is that this is being caused by a bad ethernet cable. What are the possible causes? I am in the process of testing the ethernet theory now.

  I've installed Backtrack 5R3 KDE, and I realized that my wireless is not working, but wired is working fine.

• Network configuration with limited hardware

  - by Pavel

  I have cable internet and I have two PC. One of them has wireless and ethernet, the other pc has ethernet only. Also, I have a dsl modem that has wireless builtin (some common speedstream model). My goal is to connect all of them so that both have internet access. As I understand, I have two options: connect speedstream to the cable and then connect other PC's to speedstream; OR, connect pc with wireless to the cable and then connect the other pc that has ethernet only using ethernet+wireless through speestream. First one seems to be easy, but it doesn't seem to work. What about the other choice? Is it possible to do it?
