We have a single modem for our Phone, TV & internet. Every time the phone is used I loose the internet signal. Only using Linux,(Ubuntu 10 )there is no problem with my Windows computer ?
View 14 RepliesI'm travelling right now so am not connecting into my normal router. When using Ubuntu it connects to the Wifi and then after about 15 secs drops me out again. I I boot to Windows XP this doesnt happen.
where I should start looking tofigure out the problem? I'd much prefer to use linux
why my wireless adapter drops out when I plug in my web cam.
View 1 Replies View RelatedI'm having a really strange problem with my wifi connection on my laptop. The ethernet connection works fine and so does the wifi connection - as long as I sit within one meters range from my router! As soon as I take the laptop further away the connection drops. The router is still being found by network-manager and the signal is just below 100%, but when I try to establish a connection it fails.
I'm sitting here on a fresh Ubuntu 10.04 install, and I had exactly the same problem with 9.10. That time I went through a lot of different procedures, and in some strange way the problem was solved. I haven't been that lucky this time though, I've tried reinstalling network-manager, using ndiswrapper, installing the wireless backports package, tried all kinds of drivers.. nothing works.
There shouldn't be any problem with the connection itself; I've had a perfect connection downstairs but now I can't even connect if I stand two metres from the router! Has anyone experienced anything like this and managed to fix it? My wireless card is Atheros AR2413. This is an example from daemon.log

I have a dual booth system (ubuntu (64 bit) and windows 7 (also 64))... In both systems I have trouble with my wifi:Sometimes it works for a few hours without trouble and then I stops working every 10/15 seconds after reconnecting. In windows it keeps on reconnecting, but in ubuntu sometimes also the wifi logo/picture disappears from my panel, so I can't start wifi again or see it's status.

View 1 Replies View RelatedPinging out from my netbook (over wifi, to any host) gets ~0% packet loss. Pinging into it (from any host) gets about 50% packet loss.
The router is a Dlink-DIR615 (rev d, running DD-WRT v24-sp2) but all other hosts on it ping eachother fine. I've tried changing routing, disabling IPv6, using older kernels and using wicd, all with no luck. The wireless connections is at 100% most of the time. This could be a new problem with Maverick, but I may not have noticed it before. I believe this is causing web browsing to be really slow and causing SSH timeouts.
I haven't tried madwifi drivers or nsidwrapper yet.
Edit: just booted into Windows and it has the same problem. Could it be a hardware issue? Also tried with a static IP, with no change.
Strangely, a normal ping gets 50% packet loss, but ping -A gets < 1% loss.
Edit 2: no packet loss at all on eth0.

after maybe half an hour, the wireless download rate drops to about 110ks (and runs happily at up to 20x this until then). At that point, it will never pick back up above that rate unless i disconnect and reconnect. Once the problem occurs once, its like to reoccur about every 5 to 10 minutes until the machine has rebooted.

I have an iphone, I am trying to get internet connectivity to that phone through wifi. I dont have a wifi router. But i do have a laptop with wifi card. I am connecting to internet via cable modem. In win7 I used to create an accesspoint and do the ics from ethernet card to share via wifi card. It used to work perfectly.
Now as I am sing ubuntu, i want to do the same. I have intalled firestarter, and shared the internet connection through wifi card(wlan0).After this I created an accesspoint using the gnome network applet. Now i can connect my ifone to ths accesspoint. But there is no internet connectivity in my fone.
Has anyone else experienced a failure to connect to a mobile network. I have root access wireless tether on my Droid X and I can't seem to connect to it. It times out. My buddies windows box can, and his Iphone will as well. I can see the network just fine, just no connection. Tried changing frequencies as well. And restarting both the phone and laptop.

I find all this quite annoying. What could be the solution?
It's installed as a mobile broadband connection. Only works if my phone is plugged in during boot, otherwise plugging in my phone does nothing. For example, I booted my netbook earlier today but my phone wasn't plugged in. Tethering did not work, it just acts as if it isn't present. I rebooted (with my phone still attached) and now tethering magically works.

I have a dell precision m4300 laptop with a 360 wireless bluetooth dell adapter On my system there is a debian lenny with kde3 and backported enable(everythings is p to date except bluez-utils and bluetooth holded at version 3.36-3)
Nowadays bluetooth more less works fine, I can send and receive single file to/from my phone (nokia n70)
The hell begin when I try to browse my phone files from konqueror...with bluetooth:/ I can see the list of all the device near me with sdp://[address]/ i can see two icons (obex file transfer & obex object push)
but I cant see or access to any file or folder into the phone.
I also try to update my bluez-utils to 4.60-1~bpo50+1 but in this case kbluetooth totally fail and a see the contextual menu of the system tray icon all disaled.
My laptop has an internal wireless device and a button to turn it on/off, but since it has bad reception I use an external USB wireless adapter.The problem is that if I turn the internal wireless device off using the button, it also turns the USB wireless adapter off.Is there anyway to use the killswitch (the button) only for the internal wireless device?This only started to happen in Ubuntu 10.04.

I have ubuntu 9.10 server installed, I am connecting with putty over ssh 22. but after a while (about 20-30 mins) the connection drops. and I have to connect again. is there any configuration for that?
View 2 Replies View RelatedI am running Ubuntu 9.10 on a Dell Inspiron E1505 and I am having problems with my wireless. It is a Broadcom B43xx series wireless card. I have the restricted drivers installed but I have trouble with it maintaining a constant connection. I attend a college where in order to connect to the wi-fi you need to have their certificates installed.The wireless certificates are installed and I'm telling Ubuntu to use it in order to connect but it drops in and out. I will be connected for a minute or two but then it will randomly drop out on me. I know its not my wireless hardware because any other wireless that I connect to off campus works perfectly fine. Any ideas on how to get this to work correctly?
I hate to bring this OS up but my Windows 7 connects perfectly. (On the same laptop. I triple boot: Ubuntu, Windows 7 [gaming OS] and Backtrack4 )If it helps any the wireless AP uses WPA2-Enterprise, PEAP, and MSCHAPv2 authentication, and the CA certificate (which I have selected to use), plus my user name and password.
I'm not sure if this is an issue with Ubuntu or with the BIOS. Basically when I start up my computer, the ondemand governor seems to work just fine (ranging from 800 MHz to 2200 MHz). However after some indeterminate amount of time, it will get stuck at 800 MHz and I'm not able to figure out how to get it to scale properly again.
When I restart my computer, it acts normal again for some time before locking in at the lowest frequency.
It seems like it may be related to this post: [URL]. The last post in that thread mentioned that it could be related to the temperature, that may be the case in my situation. Even if the temperature is low after it locks to the lowest frequency, it won't increase the speed as needed
My question is, is there any way to override this and let the CPU continue to run at higher frequencies once it locks down to the lowest frequency? My computer doesn't feel like it's getting that hot (it's a laptop), and I'd like to not have to be able to restart it every time this happens.
I have a pc which has 2 network cards, 1 wifi and 1 ethernet card.
I'm using wifi card to connect to wifi network (internet) and i'm planing to share this wifi/internet connection via ethernet to wireless router (siemens sx763) so i can have internet on my other devices, e.g. mobile phone, laptop.
I am running (K)Ubuntu Lucid 10.04 64bit on a Dell Latitude E6400, WiFi Card Intel 5100. Never had any problems with networking. Up to about 2 weeks ago. I do realize there have been quite a few posts with this network adaptor, but non really described the problem I have here.
What happens is that suddenly the WiFi LED on the computer stops blinking, the WiFi connection gets disrupted, and the device is not recognized anymore when checking ifconfig. Only cold restarting the machine helps then... it will work for a while (between 1 and 20 minutes) and then crash again.
On Windows 7 the card works perfectly fine. With Ubuntu 11.04 in Live CD mode I have the same effects (connection crashes after a while). Also tried booting an older kernel, no success.
My exact hardware:

I notived the following problems in /var/log/kern.log
Code:
We have three computers at home. I have the only one running Linux, the other two are running Windows XP and using Belkin Wireless G USB Adapters. I started using Linux around November, and used a powerline ethernet cable. (It consists of two parts. One part you plug into your router and the power socket beside it, and the other you plug into your computer and the power socket beside that. It then uses the power lines as a network, and acts like a normal ethernet cable. I used the 'Auto eth0' connection without much problem). Back then, my internet would stop working once every few hours but only for firefox. Other programs such as bittorrent and Spotify continued working.
However, since I got back from holiday a few days ago the situation's worse. The internet regularly pauses (every few minutes, including spotify and msn) for about 30 seconds, and then comes back. Downloads are not cancelled, as they are when I am disconnecting from the internet, they merely seem to pause. The other two computers in our house don't have this problem, and I have tried the wireless adapter, yet it seems to pause at the same times as the wired connection. I know that it too used to work back in November.
I got a new low power file server (Atom 330 with ion), but didn't enjoy it since.
I installed Ubuntu server 9.10 64bit.
I randomly experience connection drops. As I'm installing and testing, there are lots of ssh windows open, I transfer much data using scp from my laptop to the server (all connected to wired lan).
Connection drops are as follows: ssh windows terminate with "connection reset by peer", but not always all the ssh windows terminate. For example, I edited a mediatomb config using nano, that stayed open even with scp and all other ssh windows cut.
I also have apache2 installed because I'm running urd (a usenet download tool). It seems that when I start the deamon, connection drops. So I killed apache2 to try out but that didn't solve the problem.
I left ping run all the time, and the server is pinging back all the time, which is really strange as I thought that a connection drop means the whole network interface going down.
When this drop occurs, I have to wait 2 minutes until I can ssh back into the server.
I also installed mediatomb, but it isn't really fun to stream a video to my ps3 as it always hangs after 5 to 10 minutes.
