Help with my sucky connection

Recommended Posts

boywonder : Good hint on unplugging the satellite box.This is the receiver box for DISH or Direct TV.If you leave it plugged into a wall jack & your PC is on the same line (not just the same jack) you will get a slowdown & sometimes more disconnects.The only thing it needs to be plugged in for is ordering pay for veiw or accessing your account for customer service .The rest of the time it can be unplugged.Mine is most of the time & I haven't had any problems receiving the channels or gotten a letter from DISH.So that makes at least 2 of us that had a slowdown from the satellite box being plugged in.

Ok I was just on Continuum a 2d multiplayer game with liek 50 people per server like astoriods multiplayer kidna thing

and my ping range is 150-220 so yeah I guess thats good:)but I still spike and have packet loss sometimes, any tips from packet loss?

DMN ~ have you looked in your game folder for the game.cfg file?

. . .you might be able to lower the packet size there.

Do you recieve Errors in your Connection Status?

In your Modem Protocal ~ Enable Modem Error Control

and try setting the Modem IRQ Priority tweak.

right click My Computer > Properties > under Hardware Tab

open Device Manager > click on View and Resourses by type

click on Interrupt request (IRQ)

find which IRQ## is assigned to your modem

goto Start > Run type regedit and goto the PriorityControl

branch of  local_machine and what ever IRQ## is given to your modem ~

create a new value name dword  Irq##Priority

and modify the value data = 1 hexadecimal base

It should end up looking like this with the ## being

the number of your modems IRQ

HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControl

PriorityControl

Irq##Priority      REG_DWORD      0x00000001 (1)

create and add; (while your there)

Win32PrioritySeparation    REG_DWORD    0x00000026  (38)

[use hexadecimal base]

this will give more priority to what is in the forefront ~ what you see on the screen.

I have Windows ME so these may not be correct for XP

ROM-DOS : I use this IRQ tweak.I also use these in system.ini:

[386Enh]

COM3IRQ10=230400

COM3IRQ10Buffer=8760

My internal modem is on COM3

I access my system.ini this way :StartRunsystem.ini  OK This take you directly to the system.ini notepad instead of the tab in msconfig.I find this is a smoother way to tweak.

These are in my win.ini which I access the same way.

[Ports]

COM3:=230400,n,8,1,x

COM4:=115200,n,8,1,x

COM2:=115200,n,8,1,x

COM1:=115200,n,8,1,x

cholla ~ this is all I have in my system.ini file for XP;

; for 16-bit app support

[drivers]

wave=mmdrv.dll

CGA40WOA.FON=CGA40WOA.FON

I think it is only used for start-up and/or backward support.

boywonder;Thanks

on the Com03Irq18buffer=4096 try it COM03IRQ18Buffer=8760

The 8760 comes from 6 X1460 =8760 1460 being my MSS.

You can try 8192 to see if it works better.

Add this line too

COM03IRQ18=115200 or what you use for Maximum speed in you modem properties.

I'm not really just how effective the 16-bit app support is with XP but if it decreases performance you can just delete it.

DMN:I read this its indicates that AOL & Compuserve use MTU 1500 in their software.Speedguide Shows it at 1400 so I don't know. The information in the link was all for Windows 95.98 & 98SE.

Do the test at this site .It doesn't give MTU but after the test select "more details" there is a maxmss check what it says add 40 that should be your MTU.Just incase Speedguide is reading your MTU wrong.

http://speedtest.umflint.edu/

btw you need java for the test to work.

DMN;Your speed looked good on the test.It showed thw your MSS is 1360 so your MTU is 1400.Thats what speedguide's tcpip analyzer found so I guess thats what you have.

DMN if you tried the tweaks to your registry  from earlier in the topic & these didn't change you MTU or MSS then I guess it is being done by Compuserve & probably not much you can do.A call to their tech staff to ask would be the way to know for sure.If it isn't their equipment do you run through a router?

ROM-DOS ;Your MSS is 1460 so your MTUis 1500 but you already knew that.
