Optimal router settings

[basmic]

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:
---autoexc.net---
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
---eof---

STOP STOP STOP!

I can't believe you're from the UK!!!

AARRGGHH!


Anyway, getting back to the point, STOP STOP STOP!

Download <A HREF="http://www.dslreports.com/front/DRTCP021.exe" target="_new">DrTCP</A>

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!

It is fine already, but I feel I could be getting more download throughput.

BTW - why can you not believe I am from the UK?

I just assumed you were from the US.

So are you getting good results from the bandwidth tester?

You can see my results <A HREF="http://ny-monitor.dslreports.com/tweak/block:17488eb?service=dsl&speed=600&os=win98SE&via=normal" target="_new">here</A>.

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.

My advertised speeds are 600K down, 128K up.

You're using cable, yes?

Why are you choosing "dsl" from the service options on the dsl reports site?

I'll mention it again BTW. That test ins't a speed test, if that's what you were referring to.

Oh, and the ADSL Guide Site is one of the best sites for UK info on networking/ADSL info.

I realise the DSLReport site isn't a speed test. Oopsy at me for choosing DSL, however the results appear to be same (quick glance).

Do you have experience editting router's autoexec.net files? If so, anything else I could add to enhance security on my router?

If you really want to enhance the security, enable the firewall (or is it already?) and set it up properly for filtering.
