haserver telnet client problem

I have made haserver and I experienced some problems with it's telnet client window.
1. some times some incoming texts that I mean *** welcome home automation server*** like texts mix with symbols like,
%&&#lcome home automation server***
that problem comes some times in some texts

2. this is the bigest problem sometimes I cant see any of word which I write in telnet window. but after pressing 'enter' command is running and feedback msg from the server also appear correctly.

my baudrates are also ok..11.0592. should I change the MCU??

It looks like baudrate issue else controller will not misbehave like this. You can try to test it on LAN just to make sure internet is not the problem (though it should not). are you using any IC base for controller?

before that, I used 12mhz crystal for the unit and the telnet window completely misbehave with these symbols. then I got advices from the forum and then changed the crystal to 11.0592. it solved problem 99%. but above problems are still remain.
I run telnet and plug the unit to the same machine.
yes I use an IC base for controller

it may be possible that IC base is loose. Thats the reason I asked for it. I cannot really think of any other problem. Also check on CRO if your processor clock is stable or not @11.0592Mhz

ok thanx ajay sir, I'll check!!!
