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 am using ubuntu 9.10. in my area there are frequent power outage. So my wifi get disonnected as the router stops. And it asks for security code. So when power comes the router starts but i have to manually write the security code and connect to wifi again. how i can make the computer to auto connect to wifi after power comes.
View 3 Replies View RelatedI was having terribly slow internet speed with my wireless setup. I followed someone's advice and now my internet speed is flying. However, now I lose connection a lot - almost once every few minutes. Is there any reason for the changes listed below to make me lose connection so easily?
SETUP:
Ubuntu 910 - 64Bit
Wireless Router: WRT160N
Wireless Card: PCI Asus PCE N13
Changes that improved speed, but killed stability:
Radio Band frequency should be 20 MHZ,
standard channel change to 11
advanced wireless settings should be Beacon Interval 2306
Rts thres = 2307
Disable the Security easy setup*option.
Uncheck the Block Anonymous Internet Requests & reduce the MTU size to* 1400
Last week my ping was 45 this week its 80. I've checked it on three different computers, and reset my router. I called verizon (my subpar isp) they run a few test, say every things fine. I recheck my ping, its back to 45 but only last 5 mins after they check it, then it goes back to 80. I'm always having problems with them, but every time I call them the problems "just so happen" to go away while their helping me.
Anyway, my question is... Is there anyway for me to increase my ping/speed without upgrading my internet? I have 3.5 upload, .75 upload, and a Westell model 327w. I know this is a general question and not really linux related but I thought I would try this forum first since its always so helpful. I have googled this subject but I only find windows related stuff that pertains only to the programs running on the machine. They suggest things like "dont download when you want high ping" and "temporarily turn off seeding for your torrents" It is most important in windows for me though, I like to play games and a difference of 50 and 110 ping does make a difference. Of course, everything seems slower, like streaming movies and stuff.
Is there a way to increase my internet speed in ubuntu 10.10 with a wireless conection
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 5 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.

A lot of people have the problem to find themselves with Lucid Lynx 10.04 and experience massive issues when connecting to wireless - me too. As a service, here some relevant links which promise relief:

I tried all of them, and none reliably worked. Every solution which required re-association wtih the AP helped for some time, but nothing helped for long. First, don't let yourself fool by the disable IPv6 trap - while it is "enabled" it is acutally not used by Lucid! I have a clean install of Kubuntu 10.04 on an AMD64 Laptop with Broadcom STA driver: 03:00.0 Network controller: Broadcom Corporation BCM4328 802.11a/b/g/n (rev 03) However I can reliably stabilize my connection for some time either by manually disabling WiFi with the hardware switch or disabling WiFi by software means and re-activating. This brings speed at par with Kubuntu 9.10 until some time. Can anybody confirm this behaviour?
as per pytheas22, i'm attaching few details here. my download speed would starts at 470 kB/s and gradually decreases until it reaches 116 kB/s. Loading web pages seems to be fine.

But the previous kernel I built here took 55 minutes (time make -j4). The one I built after the mods (nearly same config) took 33 minutes. (make clean; time make -j4) 40%?

How do I increase the mouse speed in Ubuntu Linux? Running Gnome 2.30.0. I've already maxed out Pointer Speed Sensitivity in the Mouse Preferences control panel. I am not interested in increasing the Acceleration. Is there a config file I can edit to boost it past what the control panel allows?
I know that this mouse can track faster because it does in Windows.
I am curious if it is possible to use multiple hard drives to increase server speed. I know I could run stripped drives or RAID0, but was wondering if there is any other way to do it within Linux. My default 9.10 Server install has 3 partitions as a default. Would splitting these on three drives make it any faster?

I know you can just go to the scrunched up icon and hover it and it will appear, but is there a way to increase the scrolling speed when using a mouse wheel? It seems a little slow for my taste.
I think I seen a "bug report", for this, which really isn't a bug, but more a desired option to customize the unity launcher. Just wondering if this has been figured out, or even possible.

The ping increases with every second in a linear progression.
To exlude router as a possible problem copying to a windows 7 notebook connected to router via wifi results in an average of 2,7Mb/sec with an average ping of 150ms.

View 2 Replies View RelatedBeen trying to deal with this one for some time, and still not sure it's more or an issue on the Samba or Win 7 side.
Running Ubuntu 10.04 with Samba 3.4.7, using Windows clients from 2000 on up to access shares.
2000 and XP have no trouble both connecting initially to shares, but upon reboot the shares are disconnected and do not automatically reconnect unless one of them is double-clicked on. Passwords and mappings are saved such that Windows tries to reconnect upon restart. When manually reconnected in this way, shares remain open as they should. This isn't a big issue, but it would be preferable to have these shares reconnect so that links and shortcuts across the LAN work right from bootup.
The bigger issue is with Vista/Windows 7 - When shares are set up with appropriate passwords and such on the clients, they work as expected, until the client is rebooted. After signing into windows 2 things are observable:
- Black screen for 2-5 minutes before desktop appears
- error message appears when you try to double-click on a mapped share (even with a saved password) that the connection cannot be restored.
If you go into credentials manager and delete the saved password for the share(s) on the samba server, you are prompted for the password when you try to open any of the shares - reenter it and you're then fine until the next reboot.
There must be some issue with the persistence of the saved password, but not sure if this a Windows-side issue or not. Read some other info on this, and had to make the following changes earlier to even get Win 7 clients to connect to samba at all:
[URL]
It appears that when Win 7 starts up, it simply can't connect using the saved password, and the desktop doesn't come up until the reconnecting action(s) time out (if you disconnect your win 7 machine from the network the delay is not present).
It's not a game-breaker, but really annoying when rebooting having the delay and reentering the network share password(s).
