Why does Ubuntu really slow down the rest of my home network?

http://askubuntu.com – I have a Ubuntu desktop and a Windows 7 desktop. The Windows 7 machine is connected via wireless adapter and the Ubuntu desktop is connected via Ethernet. The wireless adapter is capable of 300Mbps link speed. When my Ubuntu is connected to the Internet, the network becomes very very slow. I have a 15 Mbps cable broadband connection. I have had many devices connected at one with no problem, yet this one connection seems to be wreaking havoc. (HowTos)

Hi everyone,

I am running Ubuntu 10.10 on a Dell Dimension 4700 desktop computer. I just upgraded to 10.10 from the previous version after getting my D-Link wireless adapter back after loaning it out. My internet now won't stay connected.

I moved from win.7 to Ubuntu (Unity) on all my machines and really like it. There is just one issue I just can't solve.

I have 3 machines at home - a desktop (with no monitor, keyboard and mouse connected) and two laptops.

The desktop is connected by a cable to the router and the laptops are connected with a solid wireless connection.

The connection quality inside the local network and outside

I am trying Ubuntu on a trial basis to see if I think I could use it in place of Windows. One of the things I can do in Windows is connect my XP laptop thru a wireless access point which is connected by ethernet cable to my desktop, which is set to share its internet connection. The desktop connects to the internet by dialup.

Hi all, i am trying to use my laptop (running Ubuntu) to take the connected wireless network to allow a separate computer (win7) to be wired to the Ethernet port and be connected to the Internet.

To reiterate,

I want to bridge my Ethernet and wireless connections so that a computer connected can use the Internet.

Modem---(wireless)---> Ubuntu Laptop---(Ethernet port)--- Win7 Desktop

I have problems with slow WiFi connection on my Lenovo notebook with Ubuntu 12.04. When I try to play MP3 or movie from my network / server connected to local network through WiFi, it plays really slow, buffer somehow. When I connect to network with cable, the speed is OK. WiFi signal is excellent.

Can you help me with that?

Hello all,

So, I have an Ubuntu 12.04 machine I am trying to connect to my 802.1x wireless network. Let's call it SSID for example. So I enter all of my credentials, it connects and displays "SSID is connected" or whatever the usuall success message is. I am able to get to the Internet and all is well.

But here is my problem.

I am building a lab environment for CCNA training, using GNS3. The GNS3 network is connected to a real network, let's call it LAN 1.

LAN 1 is not connected to the internet and is completely wired Ethernet. A single instance of GNS3 runs on a Windows 7 Enterprise host. The same host also runs a VMWare Ubuntu 10.0.04 guest.

Hi all,

I have a problem that I do not know how to investigate more. I am currently running ubuntu 12.04 since last July with no network problems at all, both wireless and LAN. About a week or more ago, my internet connection started to stop and resume randomly. Sometimes the connection also became really slow.

I just built my desktop, and connected it to the internet wirelessly shortly afterwards. I have a wireless PCI-E adapter in my motherboard. After a random amount of time(5-30 minutes), the internet stops loading. At the top corner, it still says I am connected to the internet. After clicking that icon, disconnecting, and then reconnecting once again, this same process begins again.
