Going to toss my hat in the ring here.
Just picked up a Dell Venue 11 Pro 7130 with an Intel Wireless 7260 AC and have experienced nothing but problems with it.
Info:
System: Dell Venue 11 Pro 7130
OS: Windows 8.1 Pro with Media Center
Wireless Band: AC and N
Access Points: Asus RT-AC66U (latest firmware) and Cisco AIR 3602I (7.6.130.0)
Issues Experienced:
Inconsistent connectivity to network over Wireless N and AC.
Connection dropouts while using and unable to re-connect. (Issues definitely are worse at less than 4 bars, though greater than 2)
Issues returning from sleep.
Troubleshooting done:
Drivers Tried:
Dell Supplied 16.8, 17.0.0.34, 17.0.5.8
Intel Downloaded: 17.0.6, 17.1.0
Downloaded from Station Drivers: 17.12.0.4, 17.12.0.5
Attempted to enable/disable HT/VHT
Enabled/Disabled Power saving
Enabled/Disabled u-APSD
Tried 2.4GHz and 5GHz bands
WOL enabled/disabled
WoPM enabled/disabled
Currently:
Running 17.12.0.5
Power saving enabled (aka "allow the computer to turn off this device to save power") **
** This appeared to work with 17.12.0.4 as well. I did not try it with any prior versions as this is what I was running when I saw the suggestion. I may try this on 17.1.0 at some point, but currently I'm just thrilled that there is some semblance of stability...
I got the suggestion to enable the "turn off this device to save power" setting from earlier in this thread. As others have mentioned that is usually what I disable first as it is almost always the cause of problems, not the solution
Things appear to be relatively stable at this time on Wireless N, but I am not hopeful. I am at work and wont be able to test the Wireless AC stability until I get home.
