Tweaking a Fiber Optic Connection?

G|-|oST · Post by **G|-|oST** » Sat Oct 20, 2001 4:51 pm

I have a direct fiber optic connection in my appartment building and the data jack will be activated in the next few days. I would like to know if anyone has any idea for any of the advanced/tweak settings I should use.

I had cable at my previous address and I got a lot of useful tweaking info for it on Speedguide, I am wondering if the settings should be similar or not.

I don't know much of technical info about the actual fiber optic connection, all I know is it uses no modem of any sort and plugs right into the network card. I am not sure what the claimed bandwidth is, but I played around on a machine connected to the same provider and the overall speed seemed a little bit better than cable or ADSL, mostly in terms of loading of the web pages.

The computer is:
AMD 1.4G
1G RAM
60G

Any advice would be much appreciated.

Welcome to SG.

Are you in the U.S.? You're going to get fiber directly into your NIC? Interesting. Seeing as how no one really deals with that, I'd like to see you speeds right off the bat. Maybe a tweak here and there might improve speed but fiber should be "the big dog in town".

How much are you paying for this?

I am in Canada, and today the installer came and activated a data jack which looks like a regular network cable connection. The claimed bandwidth is 5Mbps. I am payuing $29.95 per month (around $20 USD).

Should I basically use the settings for fast cable in the cablenut program or do I need to change anything?

Where in Canada are you?

And who is the provider?

I am in Vancouver, BC. The provider is Novus. http://www.novus-tele.com.The rated bandwidth is up to 10Mbps.

Download Cablenut from my sig below, install, reboot, install SG tweaks, reboot, take TCP/IP test on the top of the page, copy, paste results here.

Crispy, what is the RWIN for fiber optic connection

G|-|oST · Post by **G|-|oST** » Sat Oct 27, 2001 5:24 am

Well I tried using the Cablenut Adjuster but no matter which settings I used in it, the actual speed went down. I had to uninstall it get the speed back. I am thinking of simply changing the RWIN but I have no idea on the value to use. The rated speed is upto 10Mbps, I usually get just over 7Mbps on the novus speedtest, so what are some RWIN values to try?
Athlon 1.4G
1 Gig RAM
Win 2000

Set your RWIN to 64240 (report here if you dont know how).

Your connection is 10mbits per second Ethernet, or maybe 4 times as fast as the best someone might get on Road Runner.

The 10 mbits is probably shared by your entire building, so you won't really get that, but assuming you are on at the same time as everyone else, a good rwin is 1.5 times the max ping, about 200ms for North America, times 5 mbit, divide by 8 to get bytes, or 190k. Halflifer suggests 64k, which should be just fine as well.
