Ubuntu Networking :: Windows Not Getting Along - Wi-fi Router Eventually Disconnects
Aug 27, 2011
I have two computers and a wi-fi router. A notebook with Ubuntu 10.04 and a desktop with Windows 7. Whenever the notebook is on, the desktop starts having horrible Internet speed, and eventually disconnects. If I turn the notebook off (or disconnect from the network) it starts working fine again. Both computers connect to the router via wi-fi. I should also note that the connection runs flawlessly on Ubuntu.

I just installed Ubuntu this morning and don't have much time to detail my problem before my internet goes out again. I am currently running Ubuntu 9.10 (Karmic Koala?). I just got this laptop earlier this week with windows 7 and decided to put ubuntu on it via Wubi. Anyhoo, I login and then enter my wifi password and eveythings fine. I can surf the internet for a bit and everythings fine. but after a while, the wireless indicator on the keyboard begins to flicker on and off (between a connection and no connection) then starts to stall. The first thing I did was install google chrome (always the first thing to do) and I accidentally downloaded the wrong version A-OK. After I saw I downloaded the wrong version, I downloaded the correct, 32-bit version and installed it. During the download it said I had a 750kBs speed, but took much longer to download than had it been downloaded at a consistent 750kBs speed. I then tried to use update synaptic and it began to download reload all 44 packages and stalled around 38 or so. My internet then disconnected (wouldn't reconnect) and the download failed. I went back into windows uninstalled Ubuntu and then reinstalled it. After going through the first few steps again I began to update via update manager and surfed the web. After a few minutes of surfing the indicator began to flicker than just went off. I then connected to my neighbors internet, continued surfing and then the internet just crashed. I've found that when its just lightweight surfing, everythings okay, but during a download or any 2.0 surfing, then things start to get funky.

I'm having issue with my wireless connection. I'm not sure if it is the WPA security causing the issue, but I randomly lose connection to the router. The network manager then scans for available wireless routers for a bit before trying to reconnect to my router and asking for my wireless password again.

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.

Hey all, I have got this strange problem with my Slackware server acting as router and gateway to my internal network. It randomly disconnects the WAN connection after X days ( it is between 2-7 days ). This error messages occured in /var/log/messages just before it lost its WAN connection:
Feb 20 14:36:00 tml dhcpcd: eth1: failed to renew, attempting to rebind

Samba doesn't seem to disconnect on shutdown except by timing out, causing a loooong Lucid shutdown. (I can disconnect manually before shutdown by unmounting the Samba shares, and shutdown is then very fast.) Apparently Network Manager is somehow involved. I've installed a NM shutdown Samba script which works for the first user account, but not for the second user account (which was created and then put into the admin group).

I'm trying to run an RSYNC job that keeps hanging without any error messages. When I started monitoring traffic with WireShark, I found that RSYNC runs without problems for a few minutes, then starts generating endless TCP ZeroWindow warnings and eventually dies with TCP Window Full error.Has anyone seen this before?PS: I should mention that I don't know much about remote system and I'm not using SSH, just pure RSYNC.

I'm running wicd 1.7.0 on Kubuntu 10.04, with an Actiontec DSL wireless router (with an internal dd-wrt "bridged" router as well;Any idea what "magic" those lines are performing and if it's possible to make wicd do it all the time (instead of just the third time)?Very happy to pursue any debugging if anyone has any ideas, as it's pretty annoying to have to wait an extra couple minutes on every boot until connecting.

I have a Linksys router configured via Windows 7 and have to other PC's using Ubunto, and would like to share folders on the 2 Linux boxes with the Windows Laptop. I can see the windows network through the Linux machines but not vice-versa. I also have a Konica 1400W printer connected to the Linux box but can't get the W7 laptop to find it.Sharing message box states I haven't installed the correct sharing packages, but cant find them

I have been searching the forums for quite a while, to add extra Loopback adapter in Centos 5.1, but no success! Could you please suggest me the steps? in Windows, it is quite easy to add as many adapters as you want. wondering, if this is even possible in Linux? I have to run GNS3/Dynamips for router emulation and bind those Loopback adapters to virtual routers!

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?

I have a Dell Dimension 4600, dual boot with Windows XP home SP3, and Ubuntu 9.04.I have a GigaFast EE420-R ethernet router, windows has always connected to it with no problem, however ubuntu just wont, even after tons of research i still cannot figure out whats going wrong. ( [edit] I am willing to get another router, but i need to know its linux compatible, and i really don't want it to have wifi)
Both operating systems on my computer connect to the modem directly with no problem, but there are 3 computers in my family and 3 users, and i just cannot hog the modem for myself any longer.I hope to set up the other 2 computers the same way for my family so they can enjoy Linux for safe Internet usage, and so i wont have to waste my time formating and reinstalling there systems anymore to remove all the wonderful spyware malware and viruses that windows seems to so easily attract.

When I use all the band(transmission or browsing too many videos) it disconnects after few minutes and it doesn't connect again until I reboot.

I could use N and WPA2 by following this thread. If it is possible to reconnect without reboot would be a possible workaround
(I use Ubuntu Karmic x_64)

My internet disconnect mabe every second hour and I have to restart the Ubuntu to get internet again. This started to happen when I bought a new wireless card called NETGEAR WG311v3. The live CD didnt have the drivers for it so I had to download XP drivers and install it with ndisrwapper.
So my question is how do I fix it? Do other network drivers crash with my current one? If so how can I see wish one to remove?
Note that my card works fine with XP on same computer.

I have loaded ubuntu Lynx 10.04.1 as a dual boot behind XP home. I have wireless connection to the XP os via netgear wireless G router and USB 2.0 adapter. The network connection works well with the XP side. When I boot into ubuntu I am sure I have configured the network properly with the wep key and password and the network signal is alive in the work bar at the top of the screen. When I open Firefox and try to browse to ,say, ebay it asks for the passphrase again then tells me that FF is in work offline mode. When I correct this I get asked for the pass phrase again and the connection is disengaged. It just keeps asking for the passphrase and disconnecting. When I reboot into XP everything works perfectly again.

I'm using an Acer Aspire One d250 running Netubuntu 10.04. The wireless connection to my router fails at random intervals and spends most of it's time trying to reconnect. It will occasionally ask me to input the password to the network, which is already entered in the dialog box, and clicking "connect" doesn't seem to make any difference. Also, when it is disconnected from the network, none of the other computers in the house, wired or wireless, are having any problems. If there is any more information I could provide,

I use ubuntu 10.10 and disconnects from wireless at random. after it reconnects the the connection speed is very slow and unstable. It's not my router because it works fine on my sister's netbook (which is also running ubuntu) and it worked fine when I was running windows? I'm not very advanced with linux so you know. I don't have IPv6 enabled. My laptop is an "Advent QRC430" my wireless card is QCOM Q802XKG Wireless Network Card.

I have a minor Internet issue. I have a static IP address with the modem acting as a gateway only to my ISP. My Ubuntu server hosts my public IP address and I use pppoeconf to connect. Every 3 hours I lose Internet. I have wrote a short script to reconnect. I doubt that it is my ISP trying to renew that often.
