Disconnecting problem

Hey, first of all, I'm new to the forums !
Played TFC for some years as well as Unreal Fortress (yes the UT'99 one)

I've started playing since yesterday but I have this weird problem going on.

I've read all 'solutions' for the disconnect after 1/2 minutes but nothing helped so far.
(Forwarded my ports, reinstalled FF, No firewalls, and so forth)

In some servers I have no problems whatsoever, and I played for over 4 hours yesterday on 1 server.

But on about 75% of the servers I still get the disconnect (upper right corner of the screen: "Warning: Connection problem detected")

I run an AMD 4200+, 7900 GTO, 4 gigs of memory, and a 20mbit connection.

I've tried alot of stuff but nothing resolved the problem.

Any suggestions ?

Since it says connection problem, what's your rate, cl_cmdrate, and cl_updaterate? To find these open the console(tilde key(~), to enable go to the advanced options under the keyboard tab, and select "Enable developers console"), and type "rate" then "cl_cmdrate" and then "cl_updaterate" all without the quotes, and post what the numbers are. It could also be the server(unlikely since it happens on more than one), or just your connection, or ISP.

rate: 10000
cl_updaterate: 30
cl_cmdrate: 100

I also tried with the defaults but it doesn't make a difference

I'm having the exact same problem, getting disconnected for 90% of the servers after 20/30 seconds.

I have this problem as well but I doubt it is as high as 90%.
