Weird wireless, router, reload problem ?!?!?

[Peter Nacken]

Hey gang .. 

I cannot even really specify where that problem is coming from ...

I recently upgraded from 56K to ISDN (yeah) ... And that ISDN modem plugs
into my iBook via USB ... Then this ibook (500 mhz G3 icebook) shares that
signal via airport ...

Now .. This setup worked great under modem ... But now I have often hard
times accessing websites .. Especially on the iBooks connected to the
airport signal .. While there is no problem with Chats and email ...
Websites often give me "can't find server" messages .. I keep clicking that
Url and after 3 - 21 times later it actually pops up ...

I cannot even begin to fathom what is going on there ... The people on the
ISP side have NO clue what I am talking about (they claim to support mac,
but no one there has an idea .. When saying "I cannot even get google or
yahoo, I get a call back later 30 minutes "we checked, google and yahoo are
working fine" .. Whaaaa .. Life on the island :)

So .. Any ideas? I have heard acronyms fired at me so far (DNS, MTU) .. But
have no real idea how that comes into play ...

Thanks
