When the wireless is connected, run the following commands.
ifconfig -a
netstat -rnv

OK nothing suspicious there.

In your question you say:
I am able to connect with lan and browse websites and connect trough ssh from my win7 machine..
when I connect trough wireless I am only able to browse but no ssh access or http access..
What do you mean by you are only able to browse, but no http access.  I ask because you use browse in the wired example in relation to websites.  Just need a clarification.

Are you saying that once on the wireless, that you are unable to communicate with other devices on your LAN?

when its set on wireless..

connecting from win7 to laptop nothing works, port 22 or port 80 or any of that..
What about connecting from the Linux machine to windows?  Let's see some traceroute output from both sides please.
XK8ERAuthor Commented:
what command exactly should I use?
What is your windows' IP?
What is your IP when connected via LAN?
traceroute on Linux
tracert on Windows

Toss some ping outputs in here too.

FYI, all of these thing that parparov and I are asking are thing you should put into your original question.  The less time us experts have to spend prying all the info from you means less time until you get a correct answer :)
I would say address is very strange - it is a real white IP address, and address space is allocated to US armed forces.

OK now I'm concerned after parparovs last comment and from your last post... are the 6.6.6.x IP's fake addresses you made up just to sanitize your real IP's?

normally Router IP Address: but I canged it to since its faster to access each computer by just connecting to it like
thats the local ip address not internet.. and when I access my other windows xp boxes I use etc..
now I have made a shared folder on the win7 and typed this

mount -t cifs // -o username=admin,password=myPassword /mnt/win

now I am able to connect and its working.. weird issue..
You should never use a 6.x.x.x address in your home network. Unlike 192.168.x.x addresses they are not filtered for LAN routing and may cause collisions and drive routers crazy, since another computer in the world may use the same address. And in this specific case, a US Armed Forces computer.

If you want a prettier prefix, switch to 10.x.x.x.

okay, I know what the freaking issue is..
each time the screensaver goes on every minute the wireless goes dead.. any ideas how to disable that?
Or otherwise, in power management, you should notify power manager not to turn off the wifi

no, that's not it.. I give up. any other recommendations before I install centos v6?
I used to work fine with centos v6 but I had to install cenos v5.6 due to a software compatibility but if I cant access through ssh there is no hope.
Before you throw in the towel, setup your network properly using only RFC 1918 addresses for the internal space.  Having it setup like you do WILL cause problems, I promise.
