Browsing not possible when Skype is running

Browsing not possible when Skype is running

Often I find myself in a situation where no web browsing is possible while
Skype is running. Every browser page hangs or says "no data received".
This occurs even when accessing local pages like http://192.168.0.1
(control page of a router).
Simultaneously, wget works instantly, for example wget http://192.168.0.1.
If I close Skype, then regular browsing starts to work again.
This can't be Skype supernode loading, because this would affect wget too.
This can't be because of a glitching browser plugin, because only Internet
Explorer has one installed, while Chrome hasn't, but the pages hang in
Chrome too.
What can be the reason of such interference?
