Slow internet connection on multiple linux distros but fast connection on windows


Symptoms:
  • Less than 1 mb/s download speed
  • Frequent disconnections from the network forcing me to re-connect to it
  • Random fluctuations in speed from 45/kbs up to 600/kbs
  • Solid constant network speed of 50/mbs on windows

Troubleshooting methods already tried:
  • Restarting router
  • Trying two different network adapters(Currently using the faster adapter Tp-Link TL-WN822N)
  • Trying both linux mint and ubuntu
  • Disabling power management for each network adapter
  • Disabling IPv6
  • Updating network drivers

If anyone can help me troubleshoot this, I would really appreciate this!

One idea is to do ipconfig /all on the windows computer and compare network settings with the results of ifconfig and cat /etc/resolv.conf on the linux machine.

What Linux distro are you currenly running with what ethernet adapter (lspci will report that information)?

Whoops! I see you did this. Apologies. The information about your adapter may still be useful, though It's a shot in the dark, but, if ipv6 is enabled, try disabling it and testing again.

Is it possible there is a loop somewhere or an ip conflict on your network.

Try a static ip as well, but make sure not to asign it via the dhcp server

Wired connection to your router or WiFi? If WiFi, try with a CAT-5 cable instead to see if there is a difference.

(I'm assuming WiFi because of your "frequent disconnects" statement.)

I assume these are two different computers you are testing with. So you have the varible of two different hardware platforms as well as two different OS'es. On the Windows computer that is fast, boot that same computer with a Linux LiveCD and see what your speeds are there.

Are these 2 different computers? Or is this a dual boot situation or possibly VM installations? It is not totally clear to me.

When you say you tried Mint and Ubuntu, is this the live disks?

Ok, there is one thing not many will realize: Some ISPs give people running Windows software that "maximizes their connection". Please check to see if that software is installed or not. Also check which DNS servers your Windows PC is using vs. which ones your Linux box is using. I, personally, recommend OpenDNS as your DNS resolvers (addresses are 208.67.222.222 and 208.67.220.220).
