About 70% of the time, my computer is unable to find any wireless signals whatsoever, despite being right next to the router. When it does find the signal it connects fine and runs great, but most of the time it doesn't show any signals at all. I can't find any pattern to when it does or doesn't find the signal. My result for the "sudo lshw -C network"

I'm looking over the networking help files, as well as the troubleshooting and nothing seems to be working. [URL]. From this troubleshooting guide it tells me to open the terminal and type the command "sudo lshw -C network" and when I do, it asks me for my password but when I try to type it, nothing comes up. So I run it without typing sudo. It says "*-network DISABLED" which in the troubleshooting guide means that my router is off, but I'm clearly online on this computer as of right now.

View 1 Replies View RelatedI've just spent the entire night trying to get my computer to share Internet with my laptop. I have DSL Internet with the modem configured to bridge mode. On the openSUSE server I have two NIC's. When setting up the DSL (pppoe) it created a dsl0 which is using the NIC eth0. So now I have dsl0, eth0, and eth1 I configured eth1 for DHCP server. When I connect with my laptop using DHCP it gets an IP address just fine. However I can't access the Internet. I think my problem is in the Kernel IP Routing Table. Here is the output from /sbin/route -n

dsl0 obtains IP from ISP eth0 is set to DHCP although that confuses me because how can the same NIC have two IP Addresses? eth1 static IP 10.30.60.1
To start off I have a Rosewill rnx-n2x wireless adapter and a Dlink 4500 router. The problem is, the wireless network manager detects every wireless router in the neighborhood, except mine. I see this persons, and this persons, but no "My router Not yours". I even tried doing the hidden network setup and still nothing.
I have read that the rnx n2x isnt supported by linux, although I've seen solutions to make it work (which didn't work, mkdir command kept getting denied during make) link to what I'm talking about: [URL]. What I don't get though, is that if the rnx n2x isnt supported by linux, wouldn't I not be getting my neighbors connections to begin with?
I have a linux machine on my university network where I usually log in via ssh from home. I have know the ip, so this is what I use to log in, but it would convenient to know if my computer have a hostname on the local network (it's easier than remembering the ip).I set up a hostname when I installed linux on my pc, but it's not the name associated with that ip on the network. Is there a way to find out if there's a name associated with that ip?

Network Manager scans for other networks in range and find few but my own network is not listed. My other machine (Windows 7 OS) does not have that problem. What could be the problem? Is it the encryption of the network? I've tried with Wicd also - no progress. Did anyone else have the same problem?
View 4 Replies View RelatedI'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've been trying to find a way to watch videos from my main desktop computer on another computer I've plugged into an HDTV. I'm such a Linux newbie that I decided to give Mythbuntu a try. It was way to complicated for what I needed, and I'm sure that some more experienced people reading my first two sentences laughed to themselves at my naivety.
What I am trying to find is simple: browsing one computer's home folder from another computer, and playing the videos therein. If there's anything like Mythvideo that requires less than half of the skill requirements, I will telepathically send love to the person that informs me of it.
I am using ubuntu in my computer...i need to use my computer as a router and to run dynamic routing protocol(RIP) in my computer.I am used to router configuration and commands.but how can i use the same in my computer.
View 1 Replies View RelatedI want to show you this scheme:MyPC -> router -> internet <- router <- Mom'spc I want to connect from my pc to my mom's pc using ssh. The first router doesn't represent a problem, but my mom's router does. Our IPs are both dynamic (anyway, I can easyly know them) and I have opened the port (TCP/UDP) 2100 on the router in order to open a gateway on mom's pc.The firewall is not enabled on the router, nor on mom's pc.
Granted all this, now I should be able to connect to that computer using ssh:ssh user@ip -p 2100 But I can't, I always get a "connection refused".if I do it on my intranet, I can connect without any problem (to others computers, of course, not mom's) What's the reason because I always get a connection refused?

Also there is no wireless signal on any laptops. Mac, Win Linux, don't matter.

I'm trying to make my wireless router always give me the same ip address every boot (192.168.1.100). I do not have a static ip address from my isp.
Everything I've tried from online help has made my internet break and I'm not even sure what exactly I should be searching for on google.
Ultimately, I'm trying to get my wireless router to forward ftp requests to my computer which shares the network with an xp machine. I think this is the way to go about it.
I have a desktop computer (Ubuntu) connected to one of the LAN ports of the Cradlepoint MBR1000 router via an Ethernet cable. I also have a Verizon mobile broadband USB modem (USB760) plugged into the USB port of the Cradlepoint router.I also have a laptop (Ubuntu) with a wireless wi-fi adapter (802.11g). The laptop also has an Ethernet card but I'm not using it. The desktop computer does not have a wi-fi adapter, only the laptop does.
With the above setup, I have Internet access to both the desktop computer as well as the laptop computer, which I am well pleased with.Is there a way I can have file sharing between the desktop and the laptop, or at least ping between them, the way I have it set up? I can't use the ad-hoc method because for that to work each computer needs a wi-fi adapter. The router is using DHCP but can also be configured manually.
When one should try to connect to port 3306 of particular ip here e.g. 345.56.67.87 it should be redirected to port 3306 of internal machine. This is the scene : How can I access the particular port of the machine which is behind the router . i.e. From out side internet I would like to connect to the port 21 of the machine (192.168.5.8) which is behind router (345.56.67.87) . Here are the details I tried : both side linux (centos)
1.enabled ip forwarding of router (345.56.67.87)
2.enabled ip forwarding of machine (192.168.5.8)
3.implemented some iptable rules: /sbin/iptables -t nat -A OUTPUT --dst 345.56.67.87-p tcp --dport 3306 -j DNAT --to-destination 192.168.5.8:3306
4.iptables -t nat -A OUTPUT --dst 345.56.67.87 -p tcp --dport 3306 -j DNAT--to-destination 192.168.5.8:3306
I tried to google on it mainly it dealt with the iptable rules. of which i applied but error is" can not connect to the port 3306 of 192.168.5.8"
I setup the hostname for my linux machine to Linux. If I try ping Linux from the same computer it works. If I try from another computer inside my network the host can not be resolved. If I ping the IP from another computer it works.
I take a look in my router at DHCP client list and my linux machine doesn't have the Hostname set up.
How to broadcast the hostname to the entire network?
All settings are correct as far as i can tell. The wep key works on all my windows boxes. When i have connect automatically enabled it never tries to connect. if I go to edit it it pops kde wallet up i put in credentials. wallet goes away then nothing happens. if i double click connection to my router also nothing happens. I have the wep key in there and i even made it visible to make sure.
View 5 Replies View RelatedI'm having a strange problem with my network connection/DNS. I turn computer the on and it recognizes and connects to wireless or wired but I can't access any Internet resources or my router. If I ping the default gateway, I get no response and I get DNS errors from any network services that run at start up. If I stop and start the network daemon then it all works fine until the next time I turn on my laptop. It does this for both wireless and wired connection.
I've tried to edit the network interface information in YaST but it says that configuration is handled by knetworkmanager and I have no idea where that information is accessed. I should point out that it all worked fine until I tried to connect to open WAP at my school and couldn't so I connected to the wired network. Next morning I had this problem when connecting to my home network. My questions are 1. What could be the cause of this error and 2. where does one configure the network interfaces when using knetworkmanager
So up until I updated from Opensuse 11.3 to 11.4, I hadn't any issues with my network connection. At least none worth mentioning. Once I installed 11.4, I've had weird issues with varying lengths of connection. Sometimes I can't connect anywhere, sometimes I can only get to the router, sometimes I'm 100%. I'd fiddle with YAST until everything worked. I honestly have no clue whether or not anything I did had any effect.
Enough of the iffy history, here's what's happening now. For the past few weeks up until last night, I have been at 100% connectivity. I never turned off my computer until last night (it just shut itself off, like the cord was unplugged. I dunno what happened, maybe it was my foot, maybe the PSU. I think it has happened before.). When I turned it back on, I was only able to connect as far as my router (192.168.1.1, a D-Link Gaming router that has always been very good to me). I could not make it to my modem (192.168.0.1, a Quest DSL modem. Once I can get here, then usually I'm good to go 100%).
I tried again this afternoon, and no change. I then get the crazy idea to unplug the ethernet cable from it's PCI-card home and return it to the onboard port (which I long ago declared defunct). Immediately after plugging it into that port, I ran "ping 192.168.0.1" and I started getting returns. I open up Firefox and try to load an external page, and nothing happens. I go back to the console that I was pinging from, and it had stopped. I start pinging my router, and no luck. What I conclude from my little experiment is that the router is not at fault.
1. It did not change at all between being at 100% and being at 0% after reboot.
2. I was able to get returns from the modem, past the router, for a brief period of time while using the defunct ethernet port.
Since I never had these problems before updating to 11.4, I'm inclined to believe that it was the update that started these problems.
I have an old hp that i installed ubuntu on and I was wondering how I can turn it into a real router. By real router I don't just mean broadcast the internet but use security software, configurations, and all the stuff normally found on a real router. What are the steps i need to take? I dont have 2 NIC's in it just one but I do have a wireless usb that I can just stick into it.
