wireless failure after norton update

Hi, Tuesday evening (Swedish time) I was on the net via wireless connection. Immidiately after a Norton update my wireless connection died and my connected speakers did not work. I updated norton again last night, but still same problem. It says "no connection, use machine switch". Now I've read some of the discussion and realise that many out there have problems. Could anyone explain (to a computer idiot) what I should do? Just wait for yet other updates from Northon and hope that resolves the problem / unstall Norton, or..?

Thanks

M
