Anyone else having a problem sending messages in chat?

First I must admit I dont know what the command is to bring up chat I always have to wait for my team to start

But then when I type text and hit enter the text does not send it just sits there even if I hit the send message button.

about a third of the messages go through.

I also have problems joining games where I get a message no response from host..... and games are green and unlocked when it happens..

Any assistance would be appreciated

Thanks!!!
