i was scanning my external ip address with nmap and noticed during the scan the internet connectivity on my iphone which is on the network wireless really suffered, couldn't load a webpage.. but was connected to the internet.

the connection to my other 2 devices which are hardwired to my router seemed to be unaffected.

so the nmap scan itself appeared to be causing a dos on my wireless devices...

is this usual, or not possible..

scan settings were -
-sS -sU -T4 -A -v -PE -PP -PS80,443 -PA3389 -PU40125 -PY -g 53 –script

i did get an error regarding syntax at beginning of the scan if i remember rightly, think it was the wrong type of ip address or perhaps mising a script..

has anyone ever had this happen or aware of it?
