Windows 8.1: WiFi dropping and/or "Limited"

Same issue, ended up manually updating the driver.  Now i can connect but at speeds of less than 1 meg on a 16 meg connection.  Arrg!!  I have been fighting this for a week, i have called Microsoft support and been disconnected 3 times.  

I checked Lenovo's site and they do not have my laptop listed as a supported Windows 8.1 device.  Great, maybe that's a thought for next time, but seeing as going back to 8 is an ugly mess that may not be able to occur what do I do now?  On hold with MS again, will let you know how it turns out.

When the issue first showed it was failure to connect to DNS server, and a limited connection indicator with no internet access.  I could connect to other networks no problem, it was just all my existing connections that were in place before i upgraded.  Also great, thanks for that.  After installing the latest Broadcom Driver manually as Windows refused to use it I get connected and get through DNS, but again, what's the point at 0.3 to 1meg of speed.

And yes, all my other devices still work at full speed.

At the Intel Communities Website I posted the link to earlier the issue has been prevalent for a year. Consider yourself lucky you have only been dealing with it for a week. Like I said nothing will get done unless you post about it there and call the number I listed to get reimbursed for the Intel centrino 6235 wifi card. Be proactice people don't be lazy. It's primarily and Intel issue not Microsoft so they could care less.

Also use Wireshark and post the logs from the card.

You will have much better luck reporting the issue to Intel at the Intel communities website I posted earlier and also calling the Intel number for a refund of the card. Its been an issue for over 1 year. The warranty on the card and most laptops have expired so Intel and Microsoft do not care.

Also there is a problem in win8.1 where windows continously fails to resolve the host and also slow performance. It is extremely annoying. While connected to the card it is a different issue. Still unresolved.

Sorry for my bad English.

Am also facing the same issue with windows 8.1. its connected but showing "Limited".

Lenovo G580 [ Pre installed with Windows 7 Home Basic].

Driver : Broadcom

After am update windows 8 its working well.

Now am update Windows 8.1 wifi shows "Limited".

Kindly Clear the same

Same problem here after upgrading to windows 8.1. All other laptps, iphones, ipods, ipads, androids, mac minis work. Only this almost brand new Samsung NP900X4C makes me crazy. Of cource with an Intel Centrino Advanced-N 6235. This is so stupid. And do you know? My WiFi was dropped while I was writing this reply. Goodbye MS, Welcome back Apple!

this is exactly when the Microsoft eco-system breaks down. I may not like MAC OSX as much but it all just works..... I'm being passed between MS, Lenovo and Intel as if i cared whose problem it is. As a consumer to me it's a windows pc so therefore microsoft's issue - It broke with a windows 8.1 update. My loyalty is (has been) with MS - lenovo and intel are (to me) irrelevent.

As a software developer i'm stuck in the windows world with legacy apps. But this laptop is about to have windows 7 reinstalled and my next workhorse pc/laptop is likely to be a Mac.

aaargh!
