STILL CAN'T GET MTU SETTINGS TO STICK AS OF 10/18/10
Orginally I wanted to maximize the MTU(maxium transmision unit)to help with internet efficiency and speed to 1500mtu because it is locked down at a sad 1400mtu. As a added bonus as i searched for a solution to this with my limited linux networking comands. I stumbled around and found out that this fix will also enable our captivates to tether xbox live. This works because our stock setting is too low for xbox to work. Proof it works video here (http://www.youtube.com/watch?v=h02C9Zz6hG0)
Download terminal emulator.
Make sure you have root access.
While in the terminal type:
(that will give you root permission)
cd pdp0 that is our data connection
(type LS if you want to see your all your adapters)
To see if this worked type: ip link list
If that dosn't work try and type: ip link set dev pdp0 mtu 1500
I tested my mtu at http://www.speedguide.net/analyzer.p...K_PERM=1&IP_TO
