I have the tcp/ip optimizer should i use that and what should i use under x-setup. under tcp optimizer do i choose dial up, cable, dsl, dsl pppoe, or extreme and what should i change under custom settings.

this is ridicoulous my ping is lower on my dial up then sattellite and i live out in a country part of michigan called imlay city.
direcpc is the only kind of good internet they got. we only got dial up or buissness dsl for $130 bucks a month or some T1 but all to expenseive.

thats about all i know if you need more info let me know and using x-setup or cable nut is there a way to back up your stuff because i dont want my internet to get any worse. Thanks

opmharley · Post by **opmharley** » Wed Jul 30, 2003 11:18 pm

also my pings on games are like over 1k!!!!! its crazy i was thinking of getting an asus a7n8x with amd athlon 2600 would that change anything or no as in multi play games.

ViciousX · Post by **ViciousX** » Thu Jul 31, 2003 1:47 am

Besides my DSL connection, I also have DirecPC. Your ping times aren't going to get any better, since it's a satellite connection, latency will be terrible.

It's the whole reason I got a DSL connection.

mnosteele52 · Post by **mnosteele52** » Thu Jul 31, 2003 8:05 am

Hi opmharley

sorry to say but ViciousX is right, latency is the biggest issue with satellite. There are a few things that might help, first you need to rais your MTU, if you are using XP's native PPPoE setup it should be 1480. Try the following fix from Bob C:

1) Download this file http://www.carricksolutions.com/XP_MTU.reg
2) Right click the file and choose "Merge"
3) Click "Yes"
4) Go to "Start" -> Click on "Run" -> Type in "Regedt32.exe" -> Click "OK"
5) Go to this Reg Key "[HKEY_LOCAL_MACHINE\ SYSTEM\CurrentControlSet\ Services\NdisWan\ Parameters\Protocols\0]"
6) Double click on "Protocol MTU"
7) Click on "Decimal" -> Enter your desired value (I.E.: Anything less then 1480.) Use hexidecimal value 5c8 (which is 1480).
8) Click "OK"
9) Done!

Once you do that please post another TCP/IP Analyzer test and we will see if we can improve on other things.

opmharley · Post by **opmharley** » Thu Jul 31, 2003 10:23 am

my mtu is still the same after i used merge and edited the registry thing to 5c8 so whats up.

Did you reboot?

first time i did then it didnt work so right now no

Can you rephrase that? I don't understand, yes or no did you reboot after doing what I posted above/

opmharley · Post by **opmharley** » Thu Jul 31, 2003 10:48 am

ok i did reboot and under the test it stayed the same but under the registry settings it said 1480. and now my mtu is still 1420

mnosteele52 · Post by **mnosteele52** » Thu Jul 31, 2003 10:53 am

OK try using the TCPOptimizer, download it from my signature and use the following settings;

Settings tab:

select - DSL PPPoE
check - custom settings
network adapter selection - your NIC
check modify all adapters
maxmtu - 1480
TTL - 128
TCP Receive Window - 63360
MTU Discovery - yes
Black Hole Detect - no
Selective Acks - yes
Max Dup ACKs - 3
TCP 1323 Options - uncheck both boxes

Other Settings tab:

Max Connections per Server - 10
Max Connections per 1.0 Server - 20
Lan Browsing Speedup - optimized

Then select "Apply Changes" and reboot to take effect.

Also how are you connecting your modem to your pc, USB or ethernet?

opmharley · Post by **opmharley** » Thu Jul 31, 2003 11:19 am

im connecting using a usb port and i havent power cycled my modem and it runs forever also under tcp/ip optimizer everything was changed fine except under other settings max connections per server was changed to 15 and max connections per 1.0 server was also changed to 15.

my stuff is still the same under this test is there any other i should try?

mnosteele52 · Post by **mnosteele52** » Thu Jul 31, 2003 11:22 am

OK connecting via USB is most likely one of the reasons for such bad latency, you need to buy an ethernet card and connect that way.

opmharley · Post by **opmharley** » Thu Jul 31, 2003 11:29 am

so what one should i get and how would i set it up, would downloads be faster? also why aint my mtu changing anythign else i should try? Thanks

mnosteele52 · Post by **mnosteele52** » Thu Jul 31, 2003 11:32 am

It may be easier to fix your MTU if you have an ethernet card, you could then choose it under your adapters with the TCPOptimizer. As far as an ethernet card, you just need the card and a CAT5 cable to connect it from your modem to your pc. And yes your downloads will be faster.

opmharley · Post by **opmharley** » Thu Jul 31, 2003 11:50 am

is this any good do u use one if so is it any good? i found that at http://www.pricewatch.com and found some 2 doallr cat-5 cables.

Once you get a NIC we will finish tweaking your connection with CableNut.

opmharley · Post by **opmharley** » Thu Jul 31, 2003 12:52 pm

i got this, is it any good didnt realize before

Realtek RTL8139 Family PCI Fast Ethernet NIC i didnt realize it was an ethernet card till i checked tcp optimizer its already installed on our computer im not sure if it has the cat-5 cables hooked to it and all.

not sure how to have it run from my modem to my pc

mnosteele52 · Post by **mnosteele52** » Thu Jul 31, 2003 12:55 pm

That will work fine, just get a CAT5 cable (looks like a large phone cable) and you should see an ethernet port on your modem, plug one end into it and the other into your card. Only use ethernet, DO NOT use both, you may have to reset your modem and reboot your pc for it to work properly.

opmharley · Post by **opmharley** » Thu Jul 31, 2003 1:38 pm

all i see is a usb port on the modem

opmharley · Post by **opmharley** » Thu Jul 31, 2003 1:51 pm

so this is it can it fit in a usb port?

i know it will fit in my ethernet card but i dont see an ethernet port on my modem.

mnosteele52 · Post by **mnosteele52** » Thu Jul 31, 2003 2:04 pm

Then most likely your modem is USB only and that's what your stuck with.

opmharley · Post by **opmharley** » Thu Jul 31, 2003 2:13 pm

hm i guess ill just complain to my company im only getting download speeds of 350kbs and sattellite is like 700kbs and ill find out if they got ethernet modems so can we do any cable nut things now or it will only work with a ethernet connection.

opmharley- Go to mydirecway.com and sign up if you havent already... Go to downloads and get the latest version of the direcway (direcpc's new name) software and that will help latency just a little. Our office system runs about 900ms. The modems are dependent on the software. dont expect much from your upload and you wont be disapointed

opmharley · Post by **opmharley** » Thu Jul 31, 2003 11:18 pm

sweet thanks there about 700 to 900ms max is it any good for games still or not yet i dont want to install any games yet.

mnosteele52 when i did those settings they made my internet slower so i tried this program called system mechanic and i got a rating of 1mb around 1000kbs on a test on dsl reports with ur settings i was getting around 300 to 400. is there anything wrong?

mnosteele52 · Post by **mnosteele52** » Fri Aug 01, 2003 7:51 am

Can you please post a TCP/IP Analyzer test with your current settings.

here is my newest speed result from dslreports!!!

sorry about all the white i just used paint dont know how to get rid of it.

man direcpc said 200 to 400 is normal and i got 1600! thanks, id still be running at 350 if u didnt help. those people from customer support are dumb they said 350kbps was very good. and said nothing would happen if i tweaked it.

can I get in trouble for it running that high can i? Thanks

chpalmer · Post by **chpalmer** » Sat Aug 02, 2003 3:49 pm

No you wont get in trouble. The speeds are controlled by direcway. They will however, slow you down (FAP you (fair Access Policy)) if you go over a certain amount of useage in a month. Read the Fair Access Policy to find out what this is as I dont remember...
