Ok guys i need some help. I do not possess the necessary skill yet to troubleshoot this so there it goes..
I am trying to setup a 1841 with adsl and wireless wic for home use. After endless hours (i am currently studying for ccna so i am a newbie)
of reading i managed to create a configuration that seemed to me working but its not. The problem is with the wireless connections.
There seems to be an issue with most of the requests http for example, while other requests work fine. For example via http i can access youtube but
cant access other sites. Like a request timeout. Clients that are connected to the router via ethernet work fine.
Can someone check my configuration and let me know where have i messed it up?

Also the output from wireshark returns a lot of
"Duplicate to the ACK.." messages.

Ok here is an update. As you can see the MTU is set to 1492 for the Adsl Interface.
After manually setting the mtu size in my macbooks wireless card it started to work fine.
Now here is the question. Shouldnt the cisco wireless interface have a setting that would automatically
do that for the clients? Macbook has an auto MTU size which works fine with the Ethernet interfaces of the router.
Is there a way to set the MTU for the cisco wireless?
