Smart bro internet optimization

norvelas · Post by **norvelas** » Sun Aug 24, 2014 11:28 pm

so as the title says, i'm using smart bro internet and i'm in the Philippines. so i've tried many a things to increase my internet speed from using namebench to get proper DNS servers, TCP optimizer, finally making it to CTCP and such.

my problem is, i got a lot better when it comes to browsing, but gaming wise? really unreliable. i have random lag spikes that last up to 1 min playing online games with disconnections but when i load a page on a browser, it's fine. Any help would be greatly appreciated. Also, here's my results (Using Chrome to post, IE to get results):

try this !

lower your MTU by 2 bytes until your RWIN is a multiple of MSS => TCP Window: 262144 (NOT multiple of MSS)

Example: netsh int ipv4 set subinterface "Local Area Connection" mtu=1432 store=persistent

then add these lines too (Run cmd.exe => right click and Run As Administrator )

netsh int ipv4 set dynamicportrange tcp start=1025 num=48127
netsh int ipv4 set dynamicportrange udp start=49152 num=16383
netsh int tcp set heuristics disabled
netsh int tcp set global rss=enabled
netsh interface tcp set global initialRto=1000
netsh interface ip add dns name="Local Area Connection" addr=208.67.220.220 index=1
netsh interface ip add dns name="Local Area Connection" addr=208.67.222.222 index=2

not sure what you mean by this

oh i'm changing to OpenDNS? because i was using namebench to find my optimal DNS servers, is namebench not reliable or is OpenDNS just that good?

also i did everything except lowering my MTU, obviously

EDIT: so i'm testing the settings out playing RIFT PvP, not so great, i'll try LoL

TCP Window: 262144 (NOT multiple of MSS) is YOUR DEFAULT RWIN
lower from 2 to 2 bytes your MTU until you see ; TCP Window: ***** (Multiple of MSS)

ah ok i got it, so in this case i would lower to 128480. and how would i lower? i tried using DrTCP to lower but the value didn't change after i saved and rebooted (yes i ran as admin)

sorry for the really late response..i've had trouble loading the site and replying. so i did what you said..didn't really do much, more or less it stayed the same as before or the speed went lower

It not helps. Contact related Smart Bro tech and then bribe them to configure your smart bro connection...
