CS:S problems connecting...

Steam Powered Support said:

f you get any of these errors when connecting to Servers:

* Bad Parse in Client Command
* Bad Command Character in Client Mod
* Bad Command Character in Client Command
* CMD_MAXBACKUP HIT
* Host_Error: CL_ParseServerMessage: Illegible server message - svc_bad
* Host_Error: CL_Parse_Version: Server is protocol -######### instead of 47
* Host_Error: DispatchUserMsg: User Msg CZCareer/130 sent too much data (195 bytes), 192 bytes max
* svc_bad Wrote erroneous message to buffer.dat Host_Error: UserMsg: Not Present on Client ###
* Memory Could Not Be Read Error (one cause of this)
* Host error: Cl_Entitynum: #### is an invalid number, Cl_max edicts is ####
* Host error: Bad server message
* Host_Error: CL_ParseServerMessage: Illegible server message - svc_bad

and the most typical symptom is:
Whenever I connect to a (Counter-Strike) server, I get booted after 30 seconds

The #1 cause is the firmware in your router

If the server you are attached to has a router problem, you may also see this error, but in this case it isn't you it's the server. If most servers give you this error, then it's your router. If only ONE server gives you this error, it is likely a problem with that one server. If you have a stand-alone router (that is, one not built into your modem), completely bypass your router and plug directly into your modem and see if you have the disconnect problem then.

Linksys BEFSR11, 41 and 81 routers seem to be causing this a great deal with the latest firmware version available from their website. If you have the BEFSR11 or 41 router, you need to run the 1.45.7 firmware to solve this problem. The current firmware version that Linksys has on their website: (1.45.11) and some older versions (before 1.45.7) of the firmware can cause these same problems. You can download the known good Linksys 1.45.7 firmware for both the BEFSR11 and BEFSR41 V2 routers at:

ftp://ftp.linksys.com/pub/befsr41/befsr_fw_1457.zip

ActionTec DSL Modems, which have no firmware update available, also have this problem and the modem itself needs to be replaced. Please check this thread about Actiontec problems:

BEFW11S4
For Linksys BEFW11S4 the 1.44.2 firmware has been reported to be good

Measures required:

1) Disable QoS and uPnP. You need to go into the router and disable UPnP and QoS if it's there, and you should only have TCP/IP checked in the network properties for your Internet connection.
2) Disable Wireless Zero Service (included in Windows XP). You can access these settings in Control Panel > Administrative Tools > Services.

(Has a table limit where you won't be able to refresh the entire list of servers in the server browser. At ~ 8000 servers the router will go OFFLINE and reboot. Reducing your Steam connection rate might help this problem.)

Firstly remove the masterservers.vdf in the config folder.
See if that fixes it. At the very least, it should fix the refreshing problem

What router do you have?

I experienced this problem alot on my Linksys BEFSR81 8 port router. Specifically your loosing packets. If you have this router, the 2.45.5 firmware works perfectly and doesnt drop any packets. There are alot of other routers that have the same issue.




Take note, in CS 1.6 you drop (which is what they are referring to here). In source you just freeze up for about 2-3 rounds or you get fragments out of order and then you drop.
