I am entirely new to the concept of configuring routers. I have had my Netgear RP114 (with latest firmware) for almost a year now.
After googling about, I became more curious about editting the router's MTU sizes to gain a more optimal setting. I have a good usage/knowledge of DOS. It seems this is an advantage with the command-line, Unix-like interface when using Telnet to connect to the routter.
I have editted my autoexec.net file, yet, however I fully intend to explore, exploit and tweak my router.
Tips are much welcome! I guess you'll want to know my current setup before I go:
2 x Win98SE computers, 3Com 905-TX network cards in both
1 x Motorola Surfboard SB4100 cable-modem
Use NetBUI as file-transport protocol, and strictly TCP/IP for internet only. File/print sharing have been unbound from TCP/IP as a security measure.
This is my autoexec.net file:
sys errctl 0
sys trcl level 5
sys trcl type 1180
sys trcp cr 96 128
sys trcl sw on
ip tcp mss 512
ip tcp limit 2
ip tcp irtt 65000
ip tcp window 2
ip tcp ceiling 6000
ip rip activate
ip rip merge on
ip icmp disc enif0 off
ppp ipcp com off
sys mbuf debug off
sys wdog sw on
ip antiprobe 1

In the top left bos (TCP Receive Window) try the setting 12762. In the bottom right (MaxMTU) try 1458.
Save, exit and reboot. If you know how to, also change your router's MTU to 1458.
If those settings don't give a decent speed, then try 13900 and 1430.
Oh, and try the test <A HREF="http://www.dslreports.com/tweaks[/url" target="_new">here</A>. It's not a speed test, so don't expect good speeds in the results. It's a test of transmission efficiency.
STOP STOP STOP!!! ROFL!
I just re-read your post. You're using cable. Try the test first, and see what recommendations it gives. If your bandwidth efficiency is 100% and RWIN is in range and looking good etc, then leave it alone!
Dslreports.com is one of fave sites for testing my speed, however the speed test is less reliable than the tweak test, since I am located outside the US. Therefore, I will post a link to the results from a UK site.
ummm i need help...u guyz seem tu no wt ur doin...i jst got a modem sb4100... nd itz connected tu internet...everytim i try tu connect tu xbox live it saids mtu error not sufficient minimum 1354 blah blah...but wen i connect it tu d comp it wrkz fine...can anybody plz help ill really apreciate it...thnkz pz
