Small download speed

**UT8F** · May 29th, 2010

Hi,
I have a problem with Ubuntu 10.04LTS. I have 5mbits internet connection on wireless. When I downloading somethink over transmission, download speed is about ~500KB/s. But if i try to browse internet at the sime time, or download another package with browser, after some time my interned speed goes down. I mean from 500KB/s its become only ~100KB/s. Not only on torrent, but global. I mean on web browser too. And its not go up. Helps only when I reconnect my internet connecton. I mean disconnect from wifi network, and connect it again. It's OS problem, because on windows everythink ok. Sou where is the problem?

P.S. Sorry for my bad english.

hello

good o.s.

with that type of mb connection you have enought speed to connect and to do everything you want.

But if i try to browse internet at the sime time, or download another package with browser, after some time my interned speed goes down.

I think you have a poor connection

What i want to mean with that, is that the strength of the signal is poor

I mean from 500KB/s its become only ~100KB/s. Not only on torrent, but global. I mean on web browser too. And its not go up. Helps only when i turn off and turn on wifi again.

It's OS problem, because on windows everythink ok. Sou where is the problem?

ok

if you type:

sudo iwconfig

pleasse, write what happens and public it on this post.

In my case, I have a good connection 92% of 100% maximun strength

Code:


lo        no wireless extensions.

eth0      no wireless extensions.

wmaster0  no wireless extensions.

wlan0     IEEE 802.11abgn  ESSID:"JAZZTEL_E1"

pan0      no wireless extensions.

virbr0    no wireless extensions.

Link Quality=64/70 Signal level=-46 dBm Noise level=-88 dBm

It wants to mean that, if 70 is the 100% of the connection, I had 64 of this.

the signal level is better when the number is bigger

P.S. Sorry for my bad english.

I have worstest english

I found that there is no mether I'm surfing or not, after ~30min. of intensive downloading, when open only download program, download speed drops anyway. Where is the problem?
