Something is definitely amiss with networking on fc14. It works fine for a day or two but if there is no restart done during this time it will invariably (at least 5 times already) drop the wireless network, requiring a restart to resurrect it. I have witnessed it happening twice, and it's getting annoying. I never had this problem with fc13 and I don't think it was doing this after upgrading to fc14.
Anyone else experiencing this?
