I personally run Windows in a VM under virtualbox using Ubuntu as a host and have no network issues whatsoever with lagging. I feel that the network handling under Linux is far superior to Windows (I think the vast number of apache webservers on the net means I'm not alone in thinking this). It sounds to me as if the requests aren't being passed through your ...

I've used a virtual machine before (virtualbox) and running an OS like that makes the guest OS very slow and you can't use the full potential. The best is have dual boot.

What Virtualbox actually does is share the internet connection of your host (Windows 8.1), with your guest (Ubuntu 14.04). Your guest should be able to detect the wireless internet connection of your host as ethernet connection. You can check http://www.virtualbox.org/manual/ch06.html for more information about how to set this up.

Step One: Determine your gateway (router) address Open a terminal and issue the command route -n Note that my interface is wlan0 as I'm currently connected via wireless, yours will likely be eth0 Step Two: Insure that you can ping the router issue the command `ping -c4 gateway address (in my case it is 192.168.15.254) You should have 0% packet loss. ...

Please determine what frequency or channel your router is on: sudo iwlist wlan0 scan If, for example, your router is on channel 13 and your wireless driver either doesn't know or guesses what country you are in and guesses USA where channel 13 is impermissable, you might not see your router. I recommend that your regulatory domain be set explicitly. Find ...

I was having the same issue with Ubuntu/Linux Mint and I found it was related to my wireless driver. See if you have a realtek card with lspci 02:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8188EE Wireless Network Adapter (rev 01) If followed these steps to fix: sudo apt-get install linux-headers-generic linux-headers-$(uname -r) ...

You're using this Qimo - Qimo 4 Kids? According to distrowatch it doesn't appear to have been updated for about 5 years (May 2010), it (or it's kernel) might not be able to use your wireless hardware properly (I had a little wifi adapter that would "pretend to connect" but couldn't even get an address/dhcp info). I don't know if updating it would be ...

It's probably NOT your router dying. It's probably either using DNS from the router to look up each IP to host and the router is choking (don't use cheap routers for DNS or turn off the lookup feature in your torrent client... or both) ISP throttling based on packet inspection (oh, he's torrenting, start dropping traffic) adaptive shaping knocking it down ...

Visiting ec2-176-34-131-233.eu-west-1.compute.amazonaws.com in a browser takes me to https://duckduckgo.com/, so presumably duckduckgo are hosting their service in AWS, and when lsof looks up the IP address associated with that connection, it gets the AWS instance's name and not the duckduckgo service name.

As the comment above states, I may have not provided enough information to answer the question. That said, to fix my problem the network team at my workplace had to mark my MAC address for entry into the specific vlan used.

It's IP forwarding, you can implement that with a couple of commands: In the file /etc/sysctl.conf, add or uncomment the following line using your preferred text editor (vim, gedit, etc): net.ipv4.ip_forward = 1 To enable the changes in sysctl.conf you need to run the command: sudo sysctl -p /etc/sysctl.conf You may also want to configure ...

For the first part, to connect to two networks at the same time I would set up static routes. Assuming that the networks are on different subnets, you're basically telling the system, "If you need to connect to a machine with an address of 192.168.2.X, use eth0. If you need to connect to a machine with an address of 192.168.3.X, use eth1. And here is the ...

First, check to see if the interface sees your home network by scanning: sudo iwlist wlan0 scan Second, this card does not do N speeds. If your router defaulted to N only, this card may not list it as available in the Network Manager icon. Please check the router. I recommend auto B, G and N. http://i.stack.imgur.com/KBFbn.png What channel is your router ...

AFAIK, most distributions of Linux, along with most Windows versions, should automatically use the connection with the highest speed, unless the user has something specific configured.

I think it uses the last one that was connected... And uses different routes (route / iptables) to decide where to send internet traffic. In case you wanted to have 2 connections at the same time, but choose which one to use for internet traffic I know there are ways to choose between them. Luckily you didn't ask how because I don't remember at the ...

Please post output of the following commands and I'll try to help. It's easier to modify my answer here instead of in the comments. Check the path to www.google.com using TCP traceroute to port 80: sudo traceroute -n -T -p 80 www.google.com The configuration of routing: ip route The interface used to send packets to external networks: ip route get ...

In the exceptionsitelist file, move the sites you're whitelisting upwards, under the first set of comments - above the time limiting options. Here's a pastebin for an example.

What you are trying to implement is called as multihoming. Check the link here and here. These will give you an idea.

Open the program called 'Terminal' and type the commands in the grey boxes in the following order: Diagnose connectivity to router: ping <your_router_ip> If you get a response, you are connected to the router -- good. Press 'Ctrl-C' to stop the program. Diagnose DNS: ping 8.8.8.8 If you get a response, your DNS servers are not properly set. We ...

There is one thing that might help, and that is to disable bluetooth coexistence in the iwlwifi module sudo modprobe -r iwlwifi sudo modprobe iwlwifi bt_coex_active=N If it works, you can make it persistant with echo "options iwlwifi bt_coex_active=N" | sudo tee -a /etc/modprobe.d/iwlwifi.conf If it causes problems, just sudo modprobe -r iwlwifi sudo ...

You may have a problem going on with whatever DNS servers you are using. These can either be changed in the router (globally for all machines), or in Ubuntu. To do to in ubuntu go to network manager and edit connections. Select the connection that you use and select edit. Got to the IPV4 settings section and under DNS try to use googles (as a test) ...
