I have a Toshiba Satellite P755 series laptop. i7, and more relevant to this thread, an intel centrino WiMaxN6150 adapter.
F16 ran perfectly with it. Install to f17 and the wireless works perfect! ..until you try to do anything. I am always "connected". I am using a passphrase encryption and a comcast high-speed router and modem set. (they gave me a NetGear N router. the modem is theirs). The problem isnt with comcast (for the first time ever) as every other computer still has perfect internet.
Here's what happens. Computer loads, network connects very fast (unlike my HPs broadcom in f15). I load google chrome (or any browser) and the first page loads great. Sometimes the next 2 or three (new, i make sure they arent cached when trouble shooting) pages load fine. Then.. general "page cannot be found" error. This happens with only 1 tab as well as several tabs. Sometimes waiting a few minutes and reloading works, often not. Here is the strange part. Sometime when this happens, i can still open NEW pages, just not any page connected to what I'm opening. If facebook is what is "not found" i can open the fedora forums. But then any link i try to go to off of that is crashed. I can go to bing, but not search.
Again, this would make sense if these were pages i had cached. but i've deleted my google saved data to "the beginning of time" and even loaded pages ive never been to on that laptop before, and same thing, sometimes it loads, often its dead.
I DID try disabling PV6 as per someones recommendation to fix a similar issue in F16. That didnt help.
Oh and I am on the x86_64 F17
