Sometimes when i try to join a game in L4D my Internet goes down and i can't access anything that needs a internet connection bu that will normally go away when i restart my computer and internet. But I also get a lot of Connection Faliures do you have any idea why this is happening.
Thanks.

hmm thats a interesting one

can you tell us more about your system, lappy,desktop, OS,any programs running in background torrrents emule etc,have you defraged your HD any other issues with other games,internet provider, wireless??

tried verify your l4d files using file verifyer on steam ??

i'm just fishing here btw

any more info you can give us will give us a better clue as to the nature of your problem

could be a crummy firewall that has incorrect permissions set and doesnt like it when l4d does a certain something and locks the whole thing down?

Rightyho, I can tell your on BT, are you running a BT homehub? (if so what version?) also sometimes caused by beboxes or, god forbid, one of those speedtouch abominations...

Firstly win7 rules out a lot of the OS issues, if your internet is diconnecting then the usual culprit is your router having a flap. Somre routers have specific issues with number of connections through steam, always worth checking you've got latest firmware.

NOW THE IMPORTANT STUFF:

Pop into the game console and run the following:

rate 7500 (also try 9999 if that doesn't improve things)
cl_updaterate 20
cl_cmdrate 30

Now try playing, see if you disconnect. (if you quit game these settings are lost)
If this makes things better, you want to add those commands permanently to your userconfig.cfg

More advanced stuff:

I'm guessing, based on the highly unsecure (admin/admin) combo on telnetting to your router that it's a homehub. If you're happy telnetting to your router then run connection unbind application=GAME(UDP) port=27***-27*** to unbind the game ports

Am not sure how up you are on telnet, so try the rate/cl_blahblah bits first then can talk you through the telnet part if you need it.

er what am i on??

can u give me special commands so i can be as "pro" as Dan

i'm thinking CL_restartdancomp, or maybe SV_Danhastheruns 1

without actually looking I'll make a few assumptions

you've got a shiny little netgear 834 router

if you login to the router config, the username is admin

the password is the same as your ISP

Your good monkey now try mine

Apparently it appears to be my computer not my tinternet any ideas now? my computer hates l4d and therefore kills my internet because of it

did you try what I said a few posts above?

I didn't really understand what you said
ill try my best though

Actually that worked nice goin
but which file am i putting it into

go to:

C:\Program Files\Steam\SteamApps\common\left 4 dead\left4dead\cfg

edit for a file called "autoexec.cfg" - if there isn't one then you can make it in notepad etc.,

Each time the game loads any commands in that config are executed first :-)

Nah it is still happening next idea please
