Ubuntu Networking :: Can't See Router When Using N Class
Mar 30, 2010
I noticed earlier today that I was only getting a 54Mb connection with my wireless which I assume means that it is using g class to connect (I get 130Mb connection when using Windows 7). On my router setup page I changed the mode from mixed (a g & n class) to just n class and from then on I couldn't connect to the internet or even access my router home page.
My router is a Linksys WRT-160n.
Wireless card is Edimax EW-7728ln.
I appear to be using the correct drivers - RT2860.
Also using Wicd network manager

Because of the configuration of my house, I need two routers.I have a DLink ADSL router as my main router and the Belkin N1 as my repeater.I have set up the IP address in the Belkin to be 10.1.1.10 - my DLink is 10.1.1.1. I have disable the dhcp in the Belkin and set the DNS as ISP provided. [URL]..I have set the channel to 11 and in the Ubuntu Network Manger I have set the IPV4 to Link Local Only. I can see the Belkin and connect with my PC.but it will not take me through to the internet.

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 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:
net.ipv4.ip_forward=1
Then I tried this on the laptop:
sudo iptables --table nat --append POSTROUTING --out-interface ath0 -j MASQUERADE
sudo iptables --append FORWARD --in-interface eth0 -j ACCEPT
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.

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?

These r IP provided by my ISP that i've put on Fedora 8:
WAN IP:xxx.xxx.xxx.17 (eth0)
Subnet:255.255.255.252
Gateway:xxx.xxx.xxx.18
Valid static(public) IP set of 2:
IP:xxx.xxx.xxx.147 & 148 (eth1, eth2)
Subnet:255.255.255.240
i want to run xxx.xxx.xxx.147 as a web server & xxx.xxx.xxx.148 as a ftp server. but I'm able to ping only xxx.xxx.xxx.17(WAN IP) from outside world. Can any1 tell me that how can i bring my 147 & 148 IP online without router.

In the company where I work they have just installed some new machines in a class A network:
10.1.10.x
I am running debian with a static IP, this is my configuration in /etc/network/interfaces
iface eth0 inet static
address 193.106.32.232
netmask 255.255.255.0
network 193.106.32.0
broadcast 193.106.32.255
gateway 193.106.32.254
dns-nameservers 213.139.0.51 213.139.0.52
The people who I work with all run windows and did not have to make any changes to ping the new network. What do I have to change to be able to see the new network, connect via samba etc.

We have a large number of devices on our LAN with the mac prefix of 00:60:60. We want to assign these addresses from a separate address pool. I've created two classes, one to match 00:60:60 and another that I want to contain any other device. When i try to start the server I get:
/etc/dhcp3/dhcpd.conf line 33: boolean expression expected
match if not binary-to-ascii(16,8,":",substring(hardware, 1, 3))
^#this carrot should be under the last parenthesis#
Configuration file errors encountered -- exiting
Here is the relevant section of /etc/dhcp3/dhcpd.conf
class "006060" {
match if binary-to-ascii(16,8,":",substring(hardware, 1, 3)) = "00:60:60";
}
[Code].....
I've tried a few variations on that line. I've spent days trying to find any examples of "match if not" and haven't found anything. I assume it's going to be something to do with parenthesis/quote placement. Oh and this is ISC DHCP Server V3.0.4.

Currently I have a single openldap server version 2.3.32 preforming authentication on our databases as well as e-mail and other assorted programs. When we get a high volume of users, sometimes the users can not be authenticated for new e-mail sessions and what not. We have traced it back to being that our current single ldap server can not authenticate them all in a timely manner. We decided that we would put up a new ldap server and replicate the changes to it, then upgrade the older server version and replicate back to it so that both would have a current up to date copy of our configuration, and we would do a master/slave type setup.
Trying to replicate between the old server and the new server is not currently working. Here is the issue: when we try to import the schema's from the older server we get this error: slapadd: dn="cn=Domain Users,ou=Groups,dc=mydomain,dc=com" (line=247): (65) no structural object class provided I can not seem to find any information on google that shows this exact error? if this isn't detailed enough let me know what else I should post.

I've moved a linuxbox from being my gateway (nat, etc) to behind a new gateway (a DD-wrt router). For transparency purposes, I'd like to continue using the old box services, and just have the gateway in front of it.
Here's what I did:
The newgateway is setup for class C, 192.168.0.0
This configuration works, but sometimes it doesn't and I haven't figured out why yet.
At sometimes, clients on the LAN get throughput rates with very little speed loss (using speakeasy speed test). They will run at 33M on the LAN, running through both the newgateway, and the oldbox, and get about 35M with directly connected to the cable modem.
Other times, it seems nothing can talk with anyone, and I am not sure why.
I know what I have done is a little unconventional, but it's a transitional thing, and I am not sure it is the cause of the problem, although it was the last things changed.

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 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 am thinking of moving the router behind a server and connecting the server directly to the internet via a modem. Are there any security issues related to doing this? or other things I should be aware of. Iptables are implemented on the server blocking access on unused ports.

I replaced my wired router and networking has gone south on one of my boxes. It's a Dell tower, a few years old, triple boot (ubuntu 8.10, FreeBSD, WindowsXP). Old router used 192.168.254.* via DHCP, new one is 192.168.2.* via DHCP. The router replacement caused no problems for either FreeBSD or WinXP on this box, nor for any of the other boxes on the network (one of which is ubuntu 9.10).
Ubuntu 8.10 simply will not connect to the new router. I'm presuming that something somewhere down deep has been compromised and I just don't know where to start looking or what buttons to push to reconfigure correctly. Router status displays show an IP address of 192.168.2.35 for this box, booted under all three operating systems. Using network-manager to force that static address instead of relying on DHCP does not seem to help.

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 have a WRT54G router, and I would like to log on to it, but for some reason, I can't. I can ping the router, and and when I try ssh into it, ssh returns with
Code:
ssh: connect to host 192.168.1.125 port 22: Connection refused
which seems to imply that 192.168.1.125 is a valid address, for 192.168.1.1 returns
Code:
ssh: connect to host 192.168.1.1 port 22: no route to host
But I just can't log on to the router, neither via ssh, not via web.

My problem is little different then what I've seen here. I get the same message after inputting network name and password. I click connect and it just pops up again I don't get it. I'm running Ubuntu 8.10 for Ppc (PS3) I get no internet connection what so ever just the same message. The message I get is " authentication required by wireless network " What do I need to do to connect wireless to my router with my PS3 using Ubuntu 8.10? It does connect with a Ethernet Wire. I am new with Linux.

I am using Ubuntu 9.10. I just got a Linksys WRH54G wireless router. I want to protect my wireless connection by putting a password to it but when I enter the Router's default IP address (192.168.1.1) into my browser to open the 'Utility Welcome screen', the browser does not respond.
According to the Router's manual this is because PC' TCP-IP is not set to automatically obtain the IP address.

I tried to setup a Ubuntu Wired Router according to the manual but found a problem.
At the end of the doc page it says:
Code:
The problem though is that I don't have a wireless connection and what do I put at the end?
It says "bridge-ports eth1 wlan0" so should I change that to "eth1" twice or just leave "wlan0" out or how do I fix this?

My brother owns a chain of photo studios and we've just converted the computers over from Windows Vista to Ubuntu 10.10
We're setting up a wireless router at one of them right now and I can't log into the router via chrome or firefox by typing in 192.168.0.1
It just tells me there is no network connection. From what I remember I don't need internet to connect to the router to configure it.
On windows or osx it's generally a plug and play operation to getting the wireless all setup and secure.

Connected freshly installed 10.04.2 to a wireless network through a router. Everything looks correct -- IP is assigned, connection is on, the system shows up on the router -- except that there is no internet connection and I can't ping the router or anywhere else. According to the router, the wireless signal at the ubuntu system is stronger than at the sitting-right-next-to-it windows system with *working* internet. what is this? Should I replace current driver?
