Dell Venue 8 Pro frequently drops WIFI and bluetooth

Dell technical support installed new driver on April/23 but the issue still intermitting. I use the Bluetooth speaker for the you tube. Sometime it works for a while and after the you tube keep buffering and freeze the video. The question is why it's worked at first time when I got this tablet in late Feb. The problem occurred in last couple weeks. I suspected after many times of windows update. 

Had same problem yesterday while trying to watch a show on Netflix using BT headphones. The only thing I can think of is relatively low battery indicator. Disabling and re-enabling network adapter did the trick, but had failures like this for about 3 times during a 90 minute episode.

I rarely use bluetooth, but sometimes this issue occurs even w/o bluetooth, wifi cuts out after prolonged use of the tablet, and unless I reset the tablet or disable/re-enable adapter, I can't get the wireless to connect.

The tablet has the newest drivers/BIOS. Should I order a warranty replacement?

Judging by pictures of motherboard for the tablet, the WiFi/BT module is integrated into the motherboard... BTW, I found out that I still had the old WiFi/BT driver. I'll test the system with the new driver and will reply if that did it for me.

same, even with new drivers. got the following in event viewer

WLAN Extensibility Module has stopped.

Module Path: C:\WINDOWS\system32\athihvs.dll

Guys the wireless issue for the dell venue 8 pro is easy to fix.

Go to device manager under control panel.

1) Goto the Bluetooth - Bluetooth Radio - Power Management - "Allow the computer to turn off this device to save power" and make sure it is unchecked

2) Goto the USB - USB Root Hub (xHCI) and uncheck the same option

Good luck, works perfect for me after these changes... Cheers Alex

Worked for me! Thanks! I wonder why Dell didn't configure their machines like that to begin with...

Thanks,

This has worked for me, my wifi has good signal strength and from being in a connected states it randomly switched to limited and i had to restart to fix it but that didn't always work and was frustrating. as soon as i made those suggested changes, wifi went back to a connected status.

Hi,

I have tried this suggested method, but still no luck. My WiFi connection keeps dropping and the task bar icon shows "Limited" or "Not connected" very frequently, even when I am sitting right next to my home broadband router.

I have several devices connected via WiFi, even one that is a very basic Android smartphone, which never looses a WiFi connection with my home broadband.

I have tried a number of options, such as those mentioned above and those that referred to uninstalling specific Windows updates, but nothing works.

I am going to call Dell support to see what they say.

Hi to everyone,

try this, open device manager with an administrador account, open the wireless device properties, advanced, and set the wireless mode to b/g instead b/g/n. It seems the wireless device has the same problem than Intel ones, cannot use the 3 at the same time. But with the Intel you can set it to g/n and suppres the b instead the n one.

Hope a new driver will allow to suppress the b one instead the n one like with Intel devices.

I have looked where you have said and there is no option in there for me to change it, and i am logged in as my account that is admin :( 

Mine is the Realtek RTL8723BS, maybe note all wifi models have the option. Look here

www.intel.com/.../CS-025393.htm

to see how to access to the option, the "wireless mode" one should be available.

Alex, Thanks for sharing. I've wrestled with this issue ever since I bought my Dell Venue 8 Pro. George
