I'm using Ubuntu 9.04 64 bit on an Asus laptop and the wireless connection disconnects randomly for a while and keeps searching for the signal. When it finds it I have to put in my WEP key again to get it to connect sometimes only once or sometimes 2 or 3 times. This is getting quite annoying.
View 9 RepliesI have a windows installation (partition) but have installed into freespace on the same drive using the auto-partition manager, etc, and everything is fine. I got my network going fairly easily by going Preferences > Wireless and inputting SSID and WPA encryption key (PSK). My router issues an WLAN IP, I can get on the net, I can see my other Windows PCs on the network, I can reach my router, and all is good.So after several hours of mooching about and looking at things, I have updated all the Linux packages via Synaptics (following a prompt to update everything) including GRUB. My dual boot now shows two versions of the OS:
GRUB 1.7~Beta4
Ubuntu, Linux 2.6.31-19 - generic (I am booting this one)
Ubuntu, Linux 2.6.31-14 - generic
I also set up my HP F4580 printer over wifi on the network though with slightly incorrect drivers (for the F4400 series as this was recommended at the closest match). It works, and I can print a test page no problem.The only thing is that now (since doing all that) Ubuntu seems to periodically drop my connection to the network and then request the network PSK again, but when I enter it, it spends time trying to renegotiate but fails, and then re-requests the PSK, over and over and it never reconnects. I have to reboot and then I can connect again (automatically), until it drops at some random point (like 5 or 10 mins later)

My wired LAN keeps dropping randomly, average of every 30-60 minutes. Fresh install of 10.10 from iso, Been installed for about 4 days now, just performed system update today, no change.
My router actually completely resets itself. You can watch the lights power off and recycle doing their POST. Absolutely no problems in windows 7 dual boot configuration.
I am no downloading anything, not streaming, not doing anything actually. My computer is completely idle (save for BOINC) and all of a sudden my phone loses the wireless connection which lets me know that my router just reset.
Ubuntu is actually doing this, my wireless stays up indefinitely in windows. Once the router resets, it does automatically reconnect without a PC reboot, but why is it resetting my router?

Once or twice an hour or every few hours the interface will drop off. When this happens and comes back up and ssh sessions I have open will sit there and lag for 15-20 sec while, I assume, the connection is re-established. Any sessions I have open to the mySQL database will be dropped and I'll be given error messages associated with loosing connection to the SQL server. I have run a constant ping against the server and when the interface seems to drop off I'll get 10 or so host unreachable and it'll then start to reply again. This happens with both eth0 and eth1 on this Dell Poweredge 850 running 11.04. I have done a "sudo lspci -v" on both the server acting up and another Natty box that doesn't have this issue but the same hardware. They both are using the same driver versions though it seems certain options are slightly different between the two.

I've checked the cable, it's a pre-made with both ends looking good. I even swapped it out for a fresh home made cable and the problem still persists.
This is weird. I will be working on the internet with several tabs open and all of a sudden the pages won't update. I can't go anywhere - it's like I lost the connection. I am also downloading bittorrents with uTorrent running with WIne and that doesn't seem to be affected. I also have gPodder and I tried to update podcasts with that and it also hangs up as if it can't connect. The only way I have been able to solve this has been to reboot (which I just did).
View 3 Replies View RelatedI am running F13 on my Desktop (with a Ralink RT2870 wireless card) and also on my Laptop (Acer Aspire 5738Z) and am connecting to the internet via a NetGear router. On my Laptop I can connect to the internet fine with no problems. However on my Desktop when I turn my computer on it connects to the internet fine, and works, however after some time (maybe 5-10 minutes) it disconnects and the box asking for the password reappears, then I click connect but no joy.
The connection box just keeps reappearing and it won't connect again until I restart the computer (although sometimes it takes more than 1 restart!). This is not a signal issue, as my Desktop also has a Windows partition and that connects to the internet fine and does not drop off. I have installed the RT2870 driver through rpmfusion, which didn't fix the problem, although uninstalling the driver didn't stop the card from working.
I usually start up my Internet service by typing ./rc.inet1. While its connecting I usually see my routers ip address then I connect and I start browsing and everything is fine. A few times I noticed that instead of seeing the routers address it showed some other address and I could not get online. I try ./rc.inet1 stop and renew but still cannot connect, I reboot and I then see the router and I can connect. I am using slackware13, and opera10 browser.

View 2 Replies View RelatedI'm running Slackware 64 on an HP AMD Turion X2 Dual Boot with Vista. I'm using WICD from KDE 4.?. I am having trouble with my internet connection dropping. Any software that it internet based seems to hang. After 45 to 90 sec the net seems to come back up. If the software doesn't hang I've been able to check WICD and the connection appears to be fine, but it isn't very descriptive, just that I am still connected. It can be an inconvenience for Firefox but is horrible for any online game.
The game drops you in the middle of a fight or lock the game up. I don't know that I've always had this issue but I can't recall these inconveniences at the beginning of my Slack install. I also can't make a connection to a given install or system tweak. Lastly I haven't seen anything in my searches on the net. But hopefully this isn't the only incidence. AND much as I hate to say this, I am not seeing this from Vista and my family has been on line all week from Windows and aren't having the issue.
Whenever I use Ubuntu, the internet seemingly dies out randomly. It never does this for windows 7. Could it be the router coincidentally dying, or is it a problem with Ubuntu?
View 2 Replies View RelatedHere is the layout of my network:My cable modem plugs into eth0 on my ubuntu server which acts as a firewall (shorewall) and dhcp server to my lan. A dd-wrt access point is plugged into eth1 and then a bridge connecting my xbox360 and another bridge connecting a desktop computer.Everything works pretty well, except a few times a day, my network will just shut down. The wireless on my macbook and my wife's laptop will just shut down, and if my xbox is running, it will lose connectivity. It will be down for maybe a minute or two, and then come back up like nothing ever happened.I never had this problem when I had just a dd-wrt router running everything instead of my server.When I ssh into my server afterwards and run dmesg, this is what I will get:

Having major wireless issues with Linux. I have DSL and had a Westell router/modem combo and my wireless would stay up for no more than 15 mins at a time even while idle, and in order to get wireless back I have to reboot and then I can get another 5-15 mins of wireless before it drops. When it drops it prompts me for my wep key and wont accept it yet if I reboot it catches the wireless right away for a very short period. So I go out today and spend over $100 bucks on a Netgear dgn2000 thinking it would fix the problem... Nope I am still in the same boat as I was with the Westell.
I am not seeing my router model listed under the wiki link sticky.. (Edit) thought I installed ndiswrapper, it was it was in my downloads anyway I can't install it I get the following error (Not a valid driver .inf file.)I have tried 3 distros and have the same problem. I went to Netgears site in search of Linux drivers but all I found was the firmware updates. Could some one please shed some light on what I need to do to get up and running?This is a new laptop and I am pretty annoyed with myself for formatting it out of the box rather than reading up a bit more about Linux (been using for one month).I don't understand it Ubuntu 10.9 ran wireless perfect on my older system, (full install) and I have no trouble with my lap top that is running Windows.I really hope to get this resolved I really enjoy Linux and I don't want this to be the one handicap which would force me back to Windows, that would be very upsetting
Lately I have been using my window's partition due to the fact that 10.04 drops my wireless signal every 5-10 minutes, but today I downloaded the new updates and that seems to have fix the issue with the dropping of the wireless connection. Now the only problem is the internet is so slow when trying to go to webpages it times out. I have opened up firefox gone to about:config and changed the necessary lines, but still dreadfully slow.

View 2 Replies View RelatedI'm running ubuntu 10.04 on my laptop with broadcom BCM4322 wireless card.Basically what keeps happening is my wireless will stop working, then network manager will notify me that I have lost signal. It will then try and reconnect, but it never seems to be successful. The only way I can get the wireless to work again is if I disable wireless then re-enable wireless (or do a complete system restart).
However, it does not seem to have this problem at home. The only difference I can think of from home and school is either encryption types (the university uses WEP, I use WPA) or the fact that at home there is only one access point and at university there are multiple access points all with the same SSID.Anyone have any idea how to make my laptop stop dropping connection all the time?

I'm having a problem with the wireless on my Asus EEEPC 1000HE using Ubuntu 110.04. Digging into the laptop forums, it says there is a problem with wireless on some models of the 1000HE, but it is not the same wireless device and my wireless problem doesn't seem as bad as listed, so I think it's a different problem. But my problem is that if wireless drops for any reason, it will not start working again unless I either reboot the computer or click the wireless icon in the systray, click disconnect so it stops flashing (like it's trying to reconnect) and then suspend my computer or log off and back on. And it only does the latter because I added a file located at /etc/pm/config.d/00sleep_module with the one line that reads SUSPEND_MODULES="rt2800pci" (my wireless driver) So that one line seems to cause wireless to get a fresh connection after suspending (or something. I'm not a very advanced LInux user). I've tried running the command "sudo/etc/init.d/networking restart", but that does nothing for me. I'm not sure what other command to try to see if can fix it.[URL]

View 1 Replies View RelatedWhen I reboot my computer, my iptables sets itself to a policy of dropping everything, adds a bunch of rules, and a bunch of extra chains, to the effect that (due to everything being set to drop) I can't do anything. I know how to fix this from the terminal to the extent of just clearing most of it and changing the policies back. However, what I don't know is how to make it stay that way. I have a file with the iptables rules I want, so every time I start up I just run iptables-restore, but I don't want to have to do this every time, particularly since others use this computer who do not have admin privileges.
I've tried changing /etc/network/interfaces with the added code pre-up iptables-restore < (etc) But that never does anything, or if it does it just makes stuff work even less. I've tried changing init.d before based on similar info elsewhere, still no luck. I don't know how to get it to stick, and I don't know why it is defaulting to the rules it is, other than that I used a firewall app a while ago and afterwards this was the result, for which I uninstalled that app after no success using it to reverse the damage.
Two weeks ago I decided to ditch my XP install completely and switch to Ubuntu 10.04. So far so good, and I'm very happy with my decision. However, about 3 days ago, my wired connection started playing up. It keeps dropping out every 2 hours or so between 13.00 and 04.00. After dropping out, it immediately reconnects again (at least when I use Automatically DCHP config). From 04.00 to 13.00 it is more or less stable.
I tried resolving by reserving an IP in the DCHP Client Table in my router (linksys WRT120N). Additionally, I told the Network Manager to use the Manual configuration. Unfortunately these changes didn't help and the problems stay the same......
The daemon.log shows the following information code...
Our school has a small 3-computer lab in the preschool department where the kids come in and simply use Firefox to access some educational websites. Due to logistics in the building they're in we had to go with a wireless solution in the following setup:
- Apple Airport Extreme WAP
- 3 HP DX2200 desktops running Ubuntu 10.10
- 3 Trendnet TEW-664UB USB wifi chips
All was running great until we got the computers installed on site and now they are constantly dropping the wifi connection if they are even able to connect at all (which is highly hit or miss).
10.10 picked up the USB wifi card as soon as we plugged them in and showed the available networks, but actually obtaining and keeping connections is a nightmare at the point. The computers are in very close proximity to each other (only about 2-3 feet between computers) and the WAP is in the next room (other computers and mobile devices are able to connect to the WAP with full signal from the same room/location). Thats about all the detail I have off the top of my head, could this be an interference issue with the wifi cards or does this sound like an Ubunutu issue? Again we have had multiple other devices in that room all able to connect seamlessly.
I've just loaded the new Hamachi2 Linux beta with Haguichi for a GUI. Everything installed & connects OK, but the connection at the hub is dropping & reconnecting every minute or so. I tried adding a line to the sshd_config file to keep it alaive but it didn't make a difference.
View 3 Replies View RelatedHere's the situation: I've got an eee pc 901 running Ubuntu 9.10 netbook remix. I'm using it to connect to a WPA-encrypted wireless network on a WRT54GL running dd-wrt. It mostly connects and works ok, but sometimes it just stops working for no apparent reason (the netbook still shows itself as connected), but you can't get anywhere until you manually disconnect and reconnect. Other times, it will drop the connection, and then quickly reconnect (or sometimes not). Obviously, this behavior is pretty irritating. At first I thought the problem was with the router, but I checked the logs there and they all seem fine, and other computers on the same router don't have this problem. Looking at "dmesg | tail" on my netbook, I see a lot of instances of the following error, which I'm thinking is probably the problem:
Code:

I searched for that error message and I found this Ubuntu bug report: [URL] that describes symptoms that match mine. In that report, a poster mentions that he compiled and installed a new version of the wireless driver from the Ralink website, and it fixed his problem. Do you think installing a new driver would be good? Or has that updated driver already been added to the kernel since that bug report was filed? I've never compiled a kernel module before.
One other thing, I also see repeated instances of these lines (or similar ones) in dmesg, which look like they could be related.
