Hello all,

This is my first time posting here but I believe it to be the best place to ask my question and hope that someone can share their knowledge and help me find an answer. I have EastLink cable Internet and I have the fastest residential service money can buy, I get speed test results of 30mbps down and 2mbps up, that being said, my Internet was lightning fast on windows and Mac but when I installed Ubuntu, which is my favourite OS, my Internet is very slow and laggy. Sometimes it could take several minutes for a web page to load and some torrents download at 1-2 MBps and some download at under 100kb/sec, some web pages load instantly, some take longer.

I've searched other forums and one suggestion I found was turning off IPv6, I am not really sure what that is but I followed the steps provided and shut it off but did not notice much of a difference. I am basically a beginner when it comes to Linux, I use the OS for my day to day school and entertainment. I listen to music, watch movies, do school work and such since I am a university student. I really love Ubuntu and don't want to be forced to go back to Win blows, I really don't like windows at all so I would really like to solve this issue and stick with this operating system.

Any help is greatly appreciated,

Thank you in advance,

Sincerely,

Brian

If you could give us some info. Do you connect wired or wirelessly ? From terminal can you give us the results to
lsmod

lspci
and if you connect with wireless give us
iwconfig

Hello and thank you for replying, I don't use wireless, I am connected right into the router.

Make & Model of cable modem - Arris WBM760A

Make & Model of router - Dlink DIR - 655 Firmware - 1.35NA Hardware version - A3
I am connected right into the router via a Ethernet cable, two others use the Internet via wireless I am the only wired connection, although that hasn't affected it before, with windows installed I was getting 1-2mb/sec downloads and instant web page loads, not with Ubuntu though.


Here is my service from EastLink - Eastlink 30

Thank you in advance for your time and help, hope I can solve this!

Quickly browsing through that info I see no obvious problems.

What happens if you remove the dlink router and connect your pc directly to the cable modem? Is the speed the same as with the dlink or better?

What happens if you use other dns server like 208.67.222.222, 208.67.220.220 instead of the automatically assigned eastlink ones?

What happens if you disable IPv6?

Thank you again for your help and replies.

I disabled IPv6 and it seems to of helped quite a bit. I guess I am going to get the best I can since I can't plug straight into the cable modem because the other people in my building pay me for the internet. I do however, get the full 30mbps on www.speedtest.net so I am not sure I suppose I will leave it like it is because I love Ubuntu Linux.

Thank you very much for your help, it is much appreciated!

Also try using those dns servers I listed above to see if it helps. You only have to configure them on your pc, not the whole network.
