TCP window MTU question

Postby jackofall1232 on Sat Feb 23, 2013 6:00 pm

Ok I registered here to see if there are any knowledgeable people that will actually answer and help...lol (excuse my sarcasm)
I have been asking around and I have done a lot of google searches on this topic but still remain confused.
I have a dell 1501 that I just installed mint 14 on. I had UBUNTU briefly but had a lot of compatibility issues with drivers. I know that mint is almost the same as UBUNTU but for some reason I am not having those issues with Mint 14 Ok anyway back to the point. In Ubuntu I performed these functions:

sudo gedit /etc/modprobe.d/bad_list

alias net-pf-10 off

sudo gedit /etc/sysctl.conf

then added these saved and reboot

net.core.rmem_default = 524288
net.core.rmem_max = 524288
net.core.wmem_default = 524288
net.core.wmem_max = 524288
net.ipv4.tcp_wmem = 4096 87380 524288
net.ipv4.tcp_rmem = 4096 87380 524288
net.ipv4.tcp_mem = 524288 524288 524288
net.ipv4.tcp_rfc1337 = 1
net.ipv4.ip_no_pmtu_disc = 0
net.ipv4.tcp_sack = 1
net.ipv4.tcp_fack = 1
net.ipv4.tcp_window_scaling = 1
net.ipv4.tcp_timestamps = 1
net.ipv4.tcp_ecn = 0
net.ipv4.route.flush = 1


After that My internet seemed to be a little quicker
The first time I installed Mint 14 I did the same thing (and a few other things to squeeze bandwidth like force router to 56Mbps and adjust swappeness to 10) and I had problems with very low bandwidth (IDK if related) and then I took someones advice and put a code(i can't remember) in and it wiped all of my internet out and I couldnt recover it. So since it was already a fresh install I just re-installed. Now I am back to the default settings from the install.

On my Desktop (running windows 7) on wired connection I get 30-35 Mbps down and 6Mbps up. On WIFI my desktop will get 25-30Mbps/5Mbps.
My Laptop (running Mint 14) on the other hand will only get 15-20/2.5Mbps WIRED and 10-15 /1.5 Mbps Wireless . I would like to get the speeds that my desktop gets or close on the network.

Can someone KNOWLEDGEABLE please help me understand what I am doing wrong. Please don't throw random crap at me to try, that will corrupt my system or make it worse, I can do that all on my own. I would rather deal with a little slower speed if it is to keep it stable. Thanks in advance
