With Windows 8.1, the Miracast issue only allowing extended desktop and not mirroring was fixed with one of the DV8P updates, available at the Dell DV8P product support page. Off-hand, I don't recall which update it was (an Intel update, perhaps?), but the Miracast mirroring fix is listed in the update info.
so I noticed I have bios A08 went to del site and see A11 is current. I downloaded it and then saw that I have that download on the tablet already. I am sure I installed or at least try to install it? did the "fix" on this thread revert the bios? and the newest chipset drivers listed there and suggested is
5830_Chipset_Driver_67YC3_WN32_603.9600.2067.27988_A00.EXE | Update Package for Microsoft® Windows® (83 MB)
Chipset|
Release date 28 Jul 2015
|Last Updated 26 Sep 2015
I also had this on the tablet downloads as well. Did the "fix" which is network driver not chipset driver, replace this file? when I went to install this one just now it said what I had installed is same or newer than this file?
surprised this thread has died. Is everyone else's tablet wifi now working? Mine still drops multiple times daily and at different locations-it is NOT my router. The first time I can usually go to desktop, hit wifi on taskbar and troubleshoot and it will reset wifi adapter and will work. The next time that won't solve the problem and requires restart. currently running all updates listed on Dell site (although when installing some it says that what I have is newer than what I am installing so I chose not to install. Not sure how what I have can be newer than what is on their website. Also, deleted KB2883200, KB2887595, KB2903939 as read that these may be source of issue but it still persists. Of note, when I got my tablet in March, 2014t, it worked fine although I was aware that some had issues with wifi. I assumed that by the time I got mine that was solved. The problems started for me maybe last June?? Not exactly sure.
The wifi on my Venue 8 Pro used to be a bit flaky after sleeping but a quick disable-enable used to do the trick. Since updating to Windows 10 it's a complete nightmare. I am having to reinstall the driver every time it wakes up or reboots in order to get the wifi to work again.
I have tried every suggested fix that I can find on the net, to no avail. I rang Dell but they didn't seem to understand the problems and just kept going through a script of questions, after 35 mins I gave up.
I have reinstalled every driver on the Dell website, including the driver pack updated a couple of says ago and no joy. I have also tried the old driver suggested earlier in this thread but that didn't help either.
Dell-SteveB was able to confirm the issue on one of his networks, but unfortunately, it's probably outside his control to escalate it for a driver/firmware bug fix. I'm still hoping it will be properly fixed someday soon, as I love the device, but this issue makes it unreliable to use.
I have the same problem. Also i was seeing very high latency while pinging. i resolved the issue with high latency by disabling d0 packet coalescing under the advanced tab of the adapter. Finally that annoying and performance impacting issue is resolved for me.
<ADMIN NOTE: Broken link has been removed from this post by Dell>.
So now i am just left with the crashes after wake from sleep. I am going to test some more . Probably will test hibernate and connected standy to see if the results are any different.
I consider this to be a complete solution to address issue with high latency and crashed wifi upon wake from sleep. It is technically a workaround in that features are disabled, albeit functionality is only somewhat altered. This reverts to traditional power management. Also, note that this eliminates Sleep.
I have completed the following with very positive results:
Disable D0 Packet Coalescing
Disabled Connected Standby
Set power button to turn screen off
Enable Fast Start
Enable Hibernate in start menu
There are likely some additional optimizations n Advanced Power Settings. For Example:
Wireless Adapter Settings Power Savings Mode
Sleep - Hibernate After
Processor Power Management - Minimum Processor State
How to Disable Connected Standby: Touch start, type regedit, right click and Run As Administrator. Browse to the following key and change the value from 0 to 1. Exit regedit and reboot. HKLM\System\CurrentControlSet\Control\Power\CsEnabled
How to change power options: Touch Start, type Power Options. Press enter. Touch Choose what the Poer Button Does, then Change Settings That Are Currently Unavailable. All items above are listed on this screen.
How to change Advanced Power Settings:Touch Start, type Power Options. Press enter. Touch Change Plan Settings. Touch Change Advanced Power Settings. Touch Change Settings That Are Currently Unavailable.
Thanks for your reply. Although this may be an acceptable solution for a desktop computer or an older laptop, losing Connected Standby on this tablet is completely unacceptable. Without it, using the device portably and receiving notifications, skype calls, etc. while the device is in low power idle becomes impossible, which defeats the purpose of carrying it. Having to manually power the device on to check for missed calls on an interval is unfortunately no a solution.
The AR6004 wireless adapter and Bluetooth versions from LG are newer than those from Dell. I have not tested this, but it may also be possible to upgrade use these without any of the above changes as an alternate solution.
Dell 3.7.2.59655 6/4/2014 / 2.2.0.19 5/23/2014 with solution posted above
LG 3.7.2.61686 2015-07-29 / 2.2.0.22 2015-07-29 not tested yet on DV8P
CAUTION: If you are going to try this, download the files from Dell also, so that you can revert to the Dell drivers if needed.
Great feedback and thanks for offering your opinion. Just to clarify that this method does not disable any notifications. When the screen is off, all functionality is preserved. I would predict that battery drain is higher although I have not completed a screen off battery test in this config yet in order to quantify. I have to admit though, Windows fast start on the DV8P will boot in 8 seconds, from time the screen lights. Hibernate is hibernate and useful too.
As of this writing, this it is the only working solution that ensures a stable environment on the DV8P. Having used this tablet for the past two years and the non stop frustration of these wifi issues, being able to use it in such a stable manor for the first time has taken it from being the white elephant to the reliable device that it should have been in the first place.
I posted some newer driver links that I believe will be moderator approved shortly. I may also do some testing with those. I would welcome your assistance in testing various config in order to get to an even better solution than the original solution I posted.
Please run an admin "cmd", then "powercfg /a" and copy/paste/screenshot the results. After a day of use, run "powercfg /sleepstudy" and, if possible, please upload the resulting html file. That will make the situation more clear. The only way the device would notify while the screen is off without CS is if the device is in a full power state without the screen. It wouldn't be in S0 and, as other modes like S3 aren't supported by the firmware on this device, I'm guessing you may not get 24 hours without charging. Currently, on Windows 10 10586.164, I can get about 5 days in Connected Standby, which makes the device useful for my portable activities.

mine mirrored just fine so I guess I had that update. I think installing the "fix" for the wireless dropped must have caused my miracast to not work?

Unfortunately, the issue still exists for me, as well, now on Windows 10 Home 32-bit with all updates.

Same as nobody31. Still doesn't work consistently for me either. I just gave up. I only use the device for reading and note taking now.

Please run an admin "cmd", then "powercfg /a" and copy/paste/screenshot the results. After a day of use, run "powercfg /sleepstudy" and, if possible, please upload the resulting html file. That will make the situation more clear. The only way the device would notify while the screen is off without CS is if the device is in a full power state without the screen.
