I've been repeating myself for a while now on other threads, but as requested:
- Hardware used - NUC D54250
- 16GB RAM
- 480GB SSD
- Windows 7 x64 Pro (relatively clean install, all Windows updates done, all the latest Intel drivers installed as of 20/11/2014)
- Using an Intel 7260AC Dual Band card with driver version 17.1.0.19
I'm currently using a Netcomm NB304N (it's an Australian designed N300 wireless modem / router with the latest firmware installed). But that's besides the point.
I've a 6 year old laptop with an Intel 5100 half-height card that runs off said modem / router no problems from the same location as the NUC. I have suffered from limited access from sleep (and very seldom still do, but VERY seldom, and at completely random intervals, despite the "Allow the computer to turn off this device to save power" tick box being checked in Device Manager.
The problem
Serious throughput issues. The 7260 has some serious issues with speed. As an example, I cannot stream 1080 on Youtube without the thing buffering every two minutes. 720 fares a little better but still buffers and sometimes gets stuck on buffering; extremely frustrating, and embarassing when the NUC is being used for legitimate work (eg, Skype conference calls). And I am at a pains to know / find out how to resolve this. My download speeds on the 7260 are approximately 4Mbps. Upload speeds are around 1Mbps but where I live that's (proportionally at least) normal. The internet service I've signed to offers around 20Mbps, and my other machine using the 5100 card gets around 15Mbps download and around 5Mbps up.
Been using and monitoring Intel's Download Center page for the 7260 since May, but my research regarding this whole issue (throughput AND limited access) suggests this has been going on for quite a while. That's my frustration.
Troubleshooting
Well, tell me what to do as offered above and I'll do it. As it stands now, I've tweaked the settings in Device Manager, swapped out drivers left-right-and-center, BIOS settings (which have inevitably failed...). There's very little 2.4GHz interference where I am, but again, that's besides the point because the 5100 on another computer works completely fine at the same location.
Concluding
Now. I do apologise if I ever sounded confrontational. That's not intentional, rather it's the frustration setting in. But there's gotta be a point where someone from Intel tells us 'sorry we don't know and can't help', and let the problematic users move on. Well, I sort of have already with a Asus USB dongle but I don't think that was designed for 10 hours a day usage (it gets rather warm)... So yeah.
Any suggestions to fix the limited access upon wakeup once and for all, and the more annoying speed issues, is greatly appreciated.
