CS:S router settings?

d4nth0m · 15 Jun 2006 at 11:37

Hi,

When me and my brother try to play counterstrike source at the same time it lags really badly and we get pings from 500 to 900 and its unplayable, we cant even move most of the time. The strange thing is that they work absolutely fine when we play on our own.

We have 2mb BTopenworld ADSL and connect thru a router. All the previous games we have played together including original cs have worked fine.

Does anyone know why this would be? Do you need to setup anything special for cs:s in router options?

Thanks,

As long as you're not hosting games then no, nothing special needs to be done to the router.

My guess is that 2 people are maxing out the upstream of your ADSL. Short of getting more upstream I can't see a way around it.

What router?

My mate has a Linksys adsl router and 1MB connection. We were trying to play with 4 people on the network and we were getting around 300-400ms unplayable.

I knew it wouldn't be too comfortable with 4 people on 1Mb but the pings shouldn't be that high.

Turns out it was the built in firewall on the router. We disabled it and we all had pings around 30-45 and it was more than playable.

Find out if it has a firewall and disable it.

As for port forwarding, there are ports that you should forward for CSS but I never need to on my router. If it still doesn't help look on the help site on steampowered.com to find out what ports it uses.

damn i would have thought 1 connection would have easily been enough for a couple of people. We used to play original cs sharing a 56k modem.

Cool thanks Scotty - I will try forwarding ports and see if that helps it.

The upstream is the limiting factor here, not downstream. You've only got 256Kbit upstream on ADSL (unless you've got Max) which will get saturated pretty quickly with 2 people trying to use it.

You may have been able to have 2 people using a 56k modem on original CS, but you're not using original CS now so that really has nothing to do with it - modern games will want to use more bandwidth.

Dont see why you should have any lag problems, we ran it fine on a 4MB line with 3 people playing, we did use to get disconnected all the time as data was being sent to the router for both PC then it wouldnt go to the correct individual pc causing data loss. You should try this:

1. Open Notepad
2. Type clientport 27005
3. Save file as autoexec.cfg
4. Put file in this folder C:\Program Files\Steam\SteamApps\{your name}\counter-strike source\cstrike\cfg
5. Repeat this on your brothers sytem but change the clientport to 27006

If you need any help get back to me

2 people on one connection *should* be playable though, surely?

Make sure you disable the firewall though, its probably more important (if it has one that is)

Thanks all. Looks like there is a default clientport for cs:s which is 27005 and you can only have one game with that port active on the same lan. The fix is either port forwarding router or what grizzla said.
