I figured I'd check in.
- 2.4 GHz. I'm running an Asus RT-N-16 (Tomato). I do not have 5GHz capability on the router.
- Win 8.1 x64 (upgraded from Win 8)
- I think its happening on all networks. Definitely happening at home.
- Probably just my own.
- issue generally seems to happen after not using it for a while, but I', not sure.
- Haven't tried
- Asus Q550LF
- Came from the factory
My problem is that when I attempt to connect to my router I get "Limited Connectivity" although this generally doesn't affect anything. After some period of time (usually between 2 and 40 hours) speed will drop (from about 120 Mbps down/25Mbps up to about 4/4Mbps (not sure if this is all the time). Once it does this, the only way to get the speed back is to reinstall the drivers and reconnect. Speed is measured through speedtest.comcast.net and I have no reason to doubt the results as ordinary web browsing seems consistent with the results.
When I first got the laptop, I did not notice the problem. I didn't notice it until after upgrading from Win 8 to Win 8.1, however I only had had the laptop for a couple weeks when I upgraded and its not always obvious it has happened After I noticed the problem I changed drivers and it seemed to correct the problem (I no longer had a problem with "Limited Connectivity") However after another week or two, the problem came back (it MAY have been related to a Windows Update that happened just before this). However, no matter what I did, I could not get it to work again. I have tried numerous drivers however I am currently running the Intel 16.5.3.6 or an old Microsoft driver.
I have spent an inordinate amount of hours trying to fix this, and have been in contact with Asus support repeatedly. They're best advice (after trying new drivers) was to re-install Windows. Its pretty clear there are more serious problems, and they haven't been corrected. I'm too am upset that Intel has not offered any meaningful solutions to this problem and if need be will just buy a new card if someone can recommend one. It's not worth screwing around for hours on end to save $30 on a new card.
