Ubuntu Networking :: Use Laptop As Wireless Router
May 11, 2011
i wanted to know if i can use my laptop as a wifi router; with encryption password and all security so if another computer is in the range can detect the signal and then try to connect to it with the encrypt pass.
also i have one more doubt. can a wireless router be used as a wifi ethernet card and detect wifi signals nearby and connect to internet. suppose i have a wireless router and i connect it to my desktop(with lan cables) which has ubuntu installed, and theres a wifi connections nearby can i connect the desktop to the internet.
Running Ubuntu 11.04 on a Gateway LT3103U netbook. It's running fine except for that fact that when it goes to sleep (timeout or lid closed) or going into suspend or otherwise restarted/shutdown, my router restarts. It's a DLink DIR-655 that has been working fine until I changed this netbook to Ubuntu.After installing Ubuntu on the netbook, it found my SSID being broadcast and I added the connection by supplying the WPA2 password. I have full network access (local and internet).
It's just the router restarts and all my other machines lose connections. The router is using DHCP but supplying IPs based on MAC. Netbook is set to use DHCP.
Desktop Server Linux OEL 5 (not wireless) cable connected to the WRT54G router port. (I can go to the Internet with this server, but not able to communicate other computers on the WRT54G Wireless Network. Even though, the Linux Server is connected to the WRT54G router port.) From the Hyper Terminal Wireless laptop Windows/XP, I want to connect to my Linux Server.
I'm using a cross-over ethernet cable to connect a Desktop Windows 7 box, and a laptop running on SUSE 11.2. I want Windows to connect to the internet via the laptop's wireless interface.
I have a desktop PC running Ubuntu 9.10 and Windows 7, and a Eee PC 701 laptop running EasyPeasy Ubuntu 9.04. I'd like to connect the desktop to the laptop with a wired connection (eth0), then the laptop to my ADSL router using wireless (ath0).
I have a crossover ethernet cable (I bought on ebay). I have set up my laptop with a static IP address on my LAN and it uses OpenDNS.
I have added this to /etc/sysctl.conf on the laptop:
This is a variation on what I found on other sites describing how to set up a router. I don't understand iptables very well, but I gather that the above two lines should set up forwarding so that traffic from my router to the laptop will be forwarded to the desktop, and vice versa.
But this doesn't work. The connection doesn't even establish between the laptop and the desktop.
My son lost his USB Wireless stick for his Computer. I had thought I heard that if you had a second wireless router, you could use it somehow to detect the wireless router you have already set up in your home (like using a wireless card)? Is this what Ad-Hoc is? Either way, can this be done and if so how? I use a WRT54Gx2 Lynksys router and have a TRENDNET TEW-432BRP wireless router and also a spare D-link DI-514. I use ubuntu 10.04, and also wanted to know if I connected one of the router to his on the LAn port could he connect msaybe through an Ad-Hoc on my local computer here? He uses XP on his. I'm a newbie to linux and networking in general.
I'm try to setup a wireless network with my linksys wireless router and my HP laptop dual booting Vista & Suse 11.2. I have the vista networked, just fine. Where I can share files and the printer connected to my desktop. But I want to be able to use Suse in the same way, full time and to stray away from Vista. My wife and kids like easy. So I'm trying to transform them and show them something new.
I moved my server and network equipment, and now the wireless works but I cannot get my server online. I host a website, so this is kind of urgent.
I have a wireless router and can access the internet fine on my laptop. My server is wired & connected to the router. It sets up the networking properly.. ifconfig has an ip address, the default gateway is present. But I cannot ping google, or even the router. It says destination host unreachable.
So I go back to the laptop to check the router settings.. sometimes it likes to assign the server the wrong internal ip. But, I can't access the router settings either! The page (192.168.1.1) times out. Same with trying to ping the router. How can the laptop be online if it can't reach the router?
Oddly, ifconfig on my laptop reports an ip address starting with 99.233. It's always given me an internal address starting with 192.168. What's going on here? Is the router not allocating an internal ip? I use wicd to connect, if it's relevant.
We have a windows laptop that can only get a "local connection". Now it does sound like the router is forwarding directly to my laptop, instead of allocating internal ips.
I want to set up a Linux box as a wireless router to replace our existing Netgear WNR1000 router, as I believe the Netgear does not support the coming IPv6 protocol. Unfortunately, it is not flashable with OpenWRT or DD-WRT presently.
As we have Comcast, our cable modem acts as a dumb modem according to the customer support guy I talked to, and our router is the one that asks for the IP address from DHCP. Thus, when Comcast switches over to IPv6, I don't believe my existing router would work, correct?
My idea is to take a Linux box and put two NICs and a wireless adapter in it, using IPCop or Smoothwall to set up a router. I could then enable IPv6 support for when we have IPv6 with Comcast. Is that possible? Would there be a way to get BIND to hand out private IP addresses in the same subnet on the both the LAN NIC and the wireless card?
I was wondering whether or not it is possible/advisable to install and run Snort on a single laptop with a wireless router (firewall enabled)? Does Snort require root privileges and are there any other issues one needs to be aware of when installing and running software like this?
I'm having trouble getting my network set up the way that I want it/had it. You see, when I first set up my network, I just had my cable modem going directly to my standard wired router (A D-Link DI-604), which had DHCP,and was connected to all of the computers on my network. I had one switch hooked up to one of the ports of the router, but this was a regular switch, and it would not try to assign IP addresses, it would just pass through the DHCP info as I wanted.
Now however, my network setup has changed. My room mate and I both got laptops, and we decided that we wanted to have wireless access so we didn't have to constantly plug in to the router.
Now my network is set up like this: The modem is hooked up to the router(DI-604), which is hooked up on the LAN side to our computers, our switch (which is hooked up to 3 more computers), and to a wireless router card (A Gigabyte GN-BC01).
The wireless router card has two jacks for ethernet. One for WAN, and one for LAN. The LAN side we have plugged only into the computer in which the card is installed.
Now the problem is this: The wireless router card comes with DHCP by default, and it's assigning addresses to the laptops and to the computer hat it's in, and worse, the IP addresses are on a different subnet than that of the main dlink router. The Main (dlink) router assigns addresses from 192.168.0.1 (itself) to 192.168.0.254, while the wireless router card assigns addresses from 192.168.1.1 to 192.168.1.254 (itself).
Because of this, I cannot access services on the wireless network from my wired network or vice versa. The first thing I tried was setting the card to assign addresses from 192.168.0.12 to 192.168.0.253, however it just said "internal error" when I tried to do this. I decided that this may be because it sees that it was being assigned an address on it's WAN side on the same subnet. So the next thing I tried was disabling DHCP and setting the "LAN IP Address" to 192.168.0.12, hoping that the DHCP would just go through the card, like a switch. I would have set the LAN IP address to be assigned by DHCP, but this was not an option, so I decided that'd be the best thing to set it to.
Once again however, setting the LAN ip address to an address on the same subnet as that of the IP assigned to it's WAN side caused it to report an "internal error". I verified that this was the issue by setting the LAN address to several other private IP addresses to test (I.E. 10.0.0.1, 192.168.3.1, 192.168.5.12).
My question then really is: How do I set up both routers so that I can access services and computers from each network from the other network. Should I set them with different subnets and set the gateway on the wireless network to the main router? To the wireless router card? Should I put them on the same subnet? Will it know how to communicate?

I don't know how to get the wireless router to connect to the other wireless router so I can use internet on my computer. How do I achieve this wireless connection?
I've not changed my configuration, but after temporarily unplugging my laptop from the router, I can no longer persuade it to connect again.Have restarted it repeatedly, but to no avail.A similar problem has been occurring with my Huawei 3G Dongle which has suddenly started behaving.Are there any troubleshooting guides for the Network Manager's wired connections? Don't know where to start.
\How can i setup my computer (currently running Ubuntu 10.04 lts) into a router so that other laptop can have a wireless connection to it and be able to access the Internet?
Those are my authentication capabilities, obviously. I am using a WEP encryption for my wireless router and according to this, it will not allow me to connect. Is there anyway to allow that? The wireless card works just fine in Windows, even on the same network encryption type. Using a Intel Wireless/Pro 4965 ag. Note* this is my mother's router and whatnot. She won't change it the encryption type.
I installed a Tenda W322P wireless card in my dual-boot PC running both Windows XP and Ubuntu 11.04. The card worked straight out of the box on XP, but does not function correctly under Ubuntu. My apologies for any missing/irrelevant information, I am having to post this from the Windows boot so the Ubuntu settings are not directly available at the same time as internet access.I followed the process detailed here htURL...to install and configure the driver (I believe from reading other sites that this card is the Ralink RT3062 chipset), blacklisted the original RT2860 driver that was in use (couldn't even get the card to scan for wireless networks with the default driver) and restarted the interface.
Since then, sudo iwlist scan can find my wireless router but when I attempt to connect to it, it seems to enter a loop of requesting the WEP key then pausing for a while before re-requesting the key. I know I have the key value correct because it is copied and pasted from the same text file I used to copy and paste into the passkey field on the Windows boot. Attempting to connect to the router using Ubuntu also has the rather unfortunate side-effect of crashing the wireless router, killing off all other device connections until the router has been reset.
I just installed 11.04 on my laptop and the wireless works fine connecting to a AT&T 2Wire router when the ac power adapter is connected. When running on battery power I stay connected to the router but barely any information is transmitted. ie. if i restart the router connection on my computer I can load a web page like google.com then nothing else will work unless I restart the connection again. If I am right next to the router it will continue to work but very slow ( takes about a minute to load ......com when it only takes 2 seconds on ac power ). When I run windows 7 everything works fine when on battery power.Also every thing works fine on a linksys router with ac and battery power.Dell Inspiron 14R Processor: i5-2400MWireless Card: Intel Centrino Wireless-N 1030Ubuntu 11.04 Natty Narwhal
My Desktop is wired through eth0 to my wireless router. The router is connected to the internet. the ipaddress leased to my desktop was done with dhcpcd. My laptop is connnected to the wireless router through the wifi card known as device eth1 and i used dhcpcd for that also. How can I network my laptop via wifi through the router to the Desktop?
I'm sure that some of us techies have found the need from time to time to have a portable wireless bridge (see ascii art below) on our jaunts into the big bad user-woods, and I am here to ask the question of HOW to pull this off, with the least installation/configuration possible, as my tech lappy is also my main computer. What I want to do is this:
Code: (ISP) -> (wlan0 - [MyLappy] - eth0) -> (Client computer) Basically, thats a mess, so i'll explain it further: wlan0 grabs the netz, and a computer connected to eth0 via switch/router/crossover cable can access those netz.
1. No configuration on the client would be prime choice rib for me.
2. Client should be any OS/Arch.
Any grand ideas out there? Currently using FC10, with various extra repos enabled.
Oh, and N00by alert, I'm learning quick, and am not shy to try new/complicated things, just bear with me!
I have two network cards in my computer (Debian). One (eth0) is connected to the router which is connected to the internet, the other one (eth1) is connected to my laptop (Gentoo). Now I want to surf the web both on my computer and on my laptop. I obeyed some tutorials "Linux as router":
2. Laptop has IP 192.168.0.2 and this is the output of 'cat /etc/network/interfaces' on my computer:
Code:
takada:/etc/network# cat interfaces # This file describes the network interfaces available on your system # and how to activate them. For more information, see interfaces(5). # The loopback network interface
But a ping from my laptop to 192.168.1.1 (router to internet) still gives:
I have a machine running linux with 3 ethernet interfaces attached.
My Ifconfig:
My route output:
eth0 is attached to a laptop, eth1 is attached to a PC. eth2 is attached to a DSL modem, and the server is successfully acting as my internet gateway. The trouble is, my PC cannot see my laptop and vice versa. E.G. cannot ping, host seems down.
Since I have 3 Network cards in my Desktop PC I've configured it to act as a Router using GNU/Linux Ubuntu Lucid in combination with Samba so I could share my internet connection. It works on any laptop a connect to it using any of the network cards ports [regardless of the operating system installed on the Laptops], but when I plug that same network cable to any Desktop PC [regardless of the operating System installed] it doesn't even light the LED in the netcards. From the Client PC seems like nothing is plugged in the the netcards.
Recently I have installed Fedora 14 on my other laptop. It's a dual boot with Windows 7. Everything worked perfectly fine, networking included, until my friend didn't accidently turned off the wireless by pressing a wireless button on the laptop. Since then the wireless on Fedora doesn't work. It does on Windows thought. I've tried restarting the laptop few times, but the wireless still doesn't want to work again.
last night as a download was going the Internet just stopped connection. Then asked me for the WPA & WPA2 personal password. I didn't know what to put since I had already tried multiple pass words I restarted the router.Now for some reason the computer won't pick up the router wireless signal. It picks up multiple connection's around my area so I know that it's not the wireless card. The router is connected via ethernet at the moment so I know the internet works.Do I have to find the ssid? Maybe the router reconfigured it's self when I restart it and broadcasting mode turned off... I just don't know
I have a wireless router HG520s. I have enabled a hidden (nonbroadcast) mode on channel 1 with WEP encryption (64bit / 10 hexadecimal chars). Mac filter is not enabled. Name of ESSID is "homenet", everythig else is usually by default.Now, when I try to connect with my laptop (os=winxp) I can't see the essid (because it's hidden)Well I know I have to set it manually. I open windows wlan manager and go advanced (win-firewall is disabled) and create new wlan network profile to connect with, I set up the credentials, name of ap, enc wep, and the rest of stuff (I assume you know how 'hard' it is) and then I can see when refresh wireless network my own network, but the PROBLEM is that I have a Limited Access or/and no access to internet.
I remind you that router is well connected and there is internet on lan ports, but I can't access through wireless with my laptop.In fact I can only see my essid and that broadcasting is active, pwr is good, distance is not the problem. My laptop cannot get ip assigned and the same problem is with my E51 nokia (No Gateway Reply!).I think I said enough. Now any of you guys please try to explain me how's this possibleThe problem is same with ubuntu. My wife is using Win7, I'm on Ubuntu and my son he's on laptop with XP installed
I have installed Ubuntu 9.04 onto a USB stick (8mb). Works OK, it detects my Wireless Broadband, connects and works OK. But it does not detect the Wireless from my PC router. Do I need to install something to do this?
I have a computer running Ubuntu, and a MacBook Pro. I need to buy a decently cheap wireless router that I can hook up to my Ubuntu so that it will send wifi signals and I can use the wifi to go online with my MacBook Pro. I was about to get one today, but remembered how Ubuntu is picky about working with things like that. I'm only going to be using it to get signals around the house which isn't that big at all.
So what would be the cheapest and decently efficient wireless routers that I can use which Ubuntu will cooperate with?
I am having problems connecting to my new router. It just does not appear in the list of connections under Network Manager. It is not a problem with my laptop's wireless adapter as I can connect to another wireless router. It is also not a problem with the router itself - my Nintendo Wii can pick it up over Wi-Fi and use it and that is further away from the router. It also works if I ethernet it straight into the laptop.The router was provided by Sky Broadband and is a D-Link, pretty standard type of ADSL router with four ethernet ports, wireless and telephone cable socket. I am using the default settings for the SSID and network key, as well as the encryption type (WPA).Ubuntu version = 10.04. The wireless adapter is a very standard issue onboard Intel device but as I say, I can connect to my old Belkin wireless router no problem.
