I recently got karoo broadband installed, the speed is normally 8mbps but the longer I am connected to my router the slower it gets, I have to disconnect and reconnect to the router to get back to full speed, is this due to a bad wireless driver or do I need new drivers or a better router.
View 2 RepliesI have do some research by google to find out How To I slow down the speed when playing movie! And I found this: [URL]. But I not sure how can I do it!!

I am having trouble with my home network, from one computer to another both using wireless g (Ubuntu 10.04) what transfer rate should I expect/hope for when copying a file from one computer to another? My speed is consistently 220 KBps am I correct in assuming this is pretty bad?
View 1 Replies View RelatedI have very suboptimal Internet speed in Wifi with Ubuntu. Normally in WIndows 7 I get download speeds up to 800 KB/s and a very fast Wifi experience, but in Ubuntu I get 100KB/s maximum and web page load speed is very extremely slow. Also, pinging to AP often gives very high response times and a lot of lost packages while in Windows they are very low and none packages are lost. I have a Netgear wg111v3 which worked out of box when I installed Ubuntu but always with this problem. It is updated and I've reinstalled Ubuntu many times..
Also I forgot to say that in Ubuntu the connection goes down very often and sometimes will not connect again until I reboot. Again in Windows never happened that.

How do you set wireless speed in natty? I've tried
Code:
sudo iwconfig wlan0 rate 54M
but nothing happens. I've tried this with wireless enabled and disabled (using network-manager), with and without the module loaded (ath9k) and using the solution provided in some forums (adding the command in /etc/rc.local and in a script in /etc/network/if-up.d) but to no avail... link speed always shows up as 65M.
I've been using Ubuntu 8.04 for about a year and the wireless has been fine but now it's gone screwy and I can't figure out why. This has happened on my laptop and wife's who uses Ubuntu Hardy also. The speed drops to almost 0 mb/s whenever the signal strength is less than 95%.
It isn't the internet connection as vista (I dual boot) works fine below 95% signal strength. To get the internet speed to be at a level that can load an internet page, I have to within 3 feet of the router!! Both of the laptops don't use ndiswrapper, the internet connected straight away from a fresh install.
I have installed Ubuntu 10.10 on my Dell Latitude D830 laptop using the Wubi installer. Everything seems to be working fine except for my wireless connection. When I plug in my wired connection and test on speedtest.net I get download speeds of 20MB/second. However, when I switch to my wireless connection, I barely break 1MB/second. I have an Intel PRO/Wireless 3945ABG wireless adapter. I have scoured this forum, Google, everywhere I can think of to find a solution and none seem to work for me. I love Ubuntu but this might be a deal breaker...
View 3 Replies View RelatedIs there a way to increase my internet speed in ubuntu 10.10 with a wireless conection
View 1 Replies View RelatedI am connecting from this Ubuntu 9.10 computer to a WRT54G running dd-wrt, over WPA2 AES. Normally, everything works fine and I get very satisfactory download speeds; usually 1.5+ Mbps. Sometimes though, usually after restarting networking a lot, i.e. /etc/init.d/networking restart, the download speed seems to be limited to around 64-70 kbps. It also happened recently when I disconnected from a vpn with vpnc. It's really strange because it has nothing to do with changing any settings.
The only things I can think of are POSSIBLY wpa_supplicant causing problems because that's the only thing besides networking that's restarted. It could be related to my router config but I can't imagine what because it runs so fast normally. Rebooting the router doesn't fix it. Restarting the network, manually killing wpa_supplicant, rebooting the router. None of these seem to fix it. The only way I've found is to just reboot. Obviously, something breaks at some point that isn't affected again by anything but a reboot.
My wireless is flakey -- dropped connections, poor speed, etc. As diagnosis, I loaded the 'wavemon' utility so that I might watch the radio and signal and noise.Things will be good, then fall off, then get better, then go away entirely. Repeat continuously and randomly. For these experiments, my laptops -- more than one -- are on a table.The table is roughly 15-20 ft laterally from the access point. The access point is also 8 ft above the floor vs. 3 ft table height.(grin) While the signal "wobbles" everything else is mechanically stable and otherwise not moving.

I have a pretty decent DSL connection that usually gave me about 105KB/second download speed over wifi. The "official" download speed was 1.5 megabits so I should have been getting a bit more, but that's not my question.
I recently switched to Mint from Ubuntu. Now my download speed is significantly slower, to the tune of 45 KB/second. Since the connection runs at normal speed when I connect via an ethernet cable, my guess is that mint doesn't give enough power to the wifi card. Is there any way I can fix that?
I have a tenda wireless adaptor running on 11.04 natty. The USB id is: 148F 3070
Using the already installed drivers rt2800usb it can connect to all 13 channels but is very flaky, transfers slowing and stopping regularly. The rt2870sta driver is a lot more stable, but it will only connect to channels 1-11, but I need to use channel 13 due to massive wifi congestion on other channels...
I've tried iwpriv but it says there are no ioctls for the device.
Is there any way to get the installed driver rt2870sta to scan and connect to channel 13?
I've also tried to install the latest drivers from the ralink website: rt2870sta says it can see all 14 channels, but fails to scan. I also tried rt3070 driver but I cannot insmod as there are errors...
My wireless connection work just fine but it gives me wrong connection status, like 10% even when I'm seating near the wireless router or disconnect status while I steal manege to use the internet at full speed.
View 1 Replies View RelatedBasically the problem is a slow download speed over my wireless connection that does not occur in Windows Vista. The reason I'm so annoyed is that the speed is not constantly slow. It bursts at around 600kb/s (good for my internet connection). The problem is that while trying to download a file it bursts for about a second,then total throughput decreases to +/- 1kb/s for a few seconds, then another burst and so on. Note the file I'm downloading is a http:// download, not p2p or anything. I've attached a screenshot of the System Monitor.

Some additional info. I'm using Ubuntu 10.04 with all available updates installed. The browser in use is Google Chrome.
I am a Linux newbie using fc11 and wireless broadband from 3G for my personal laptop. Sometimes my download speed is up to 100+ kB/s (due to my observation from using yum command) and also there is time its only 5.6 kB/s. Its really slow. At first, I disabled automatic update so that it can work faster. It does work faster for a while and then the speed drops to around 11 or 12 kB/s.

A few months ago I invested in a very nice, expensive high performance mouse with very high resolution tracking. In Fedora 12 it is just too fast for me though, and I'm already well on the way to Carpel tunnel syndrome..
I have turned the sensitivity and acceleration down as far as they go but it is still too fast. The old ways of adjusting xorg parameters are, I understand it, now null and void due to the hotplugging HAL framework.
How to turn the speed of the mouse down on Fedora if the control panel doesnt turn it down enough.

I recently installed Open SUSE on my HP laptop with a (duh) Broadcom Wifi card. I finally got it to work, but it works very slowly. The max speed I get at my college WiFi is 5 mbits, and at home I can't access the Internet at all ,just the LAN. It works perfectly in Windows on the same machine. At my college the Internet works fine though.Anybody got some tips how to get the speed up and how to get the Internet at home to work?
View 9 Replies View Relatedabout every second time when I start up my Ubuntu 10.4, my hard drive starts to work heavily. While it's doing so I see in the system monitor that the gnome-settings-daemon has the status 'uninterruptible'. After about 3 minutes the hard drive calms down and the status of gnome-settings-daemon switches to 'sleeping'. so from that I guess the heavy working of the hard drive is somehow related to that process. Sometimes gnome-settings-daemon seems to crash completely so that my theme is gone.
So is there a solution to that? because it's annoying that it slows down the system for about 3 minutes after start up. On the net I've found some old threads from 2004 and 2006 which describe crashing of gnome-settings-daemon. But there didn't seem to be a solution.
As mentioned in another of my recent posts, I have set up a small network for my job, in which I am utilizing 4 Servers running Ubuntu 9.04 Jaunty Jackalope Gnome GUI and Ubuntu Server running underneath (yes I need a GUI for what I am doing). However, I am having a problem when bringing Ubuntu out of "locked" state, and any time that I am required to authenticate (i.e. sudo bash). After I type in my password, everything hangs for a good 3+ minutes.
To test this, I disconnected the Ubuntu Servers from the network, and I tried to authenticate again. With the server off the network, authentication did not hang, and the GUI came up in seconds. Also, I checked my syslog and memory utilization and both are well within acceptable range that they would not be causing sluggish performance.
With all of this said, I believe that there is some kind of resolution going on when trying to authenticate while the servers are connected to the network (i.e. Kind of like how doing a traceroute in a cmd prompt in Windows without the "-d" takes forever because of name resolution checking).I should also mention that my network DOES NOT have an internet connection by design.
when calling 'top' dbus is having load of activity ('dbus-monitor --session') outputs also a lot of action (see attachement). this has effect that my machine is slowing down and normal work takes ages.I have no clue where the activity is coming from. I also had a look at https://bugs.launchpad.net/ubuntu/+s...or/+bug/441828. But there are no unnormal devices plugged in... (just keyboard + cordless mouse).when starting the machine the cpu load is ~9%. After a while (after 1 day) it goes up to 70-80%. the started applications do not change during that time. so i guess somewhere there is a leak.

View 4 Replies View RelatedIt's also because I've never had any big problem. The last openSUSE I used without problems was/is 11.2(I still use it as main desktop because of problems since 11.3).The problem is - the DL speed is repeatedly drops down to around 156KB/s albeit my top speed of router-NIC combination is at 21-22MB/s. When this happen and open network manager and click/reload my wifi or restart wireless or even computer, the speed is back at the top. But after few seconds, minutes it drops down again, and so on. I made some images(to see it on the network manager draphs):after that drop-off:and restart wireless:Best chance to see it is when downloading more files with FreeRapidDownloader or JDownloader. Upload speed is OK. The first time I've seen this problem in 11.3, which i've skipped in hope that 11.4 will be ok and now, as the EOL of 11.2 is coming I'd like to go on.It's also desktop and installation media independent(Gnome works similar, DVD, LiveCD).I've checked many other distributions and none of them had this problem. But openSUSE is my love, so i need and want to solve it
