RE: Dell Venue 8 Pro WiFi Issue

Jump to solution

The 64GB tablet lost WIFI entirely today.  I even rebooted my U-verse 2Wire gateway to make sure it was not a network problem.  5 computers and 2 phones connected no problem most using WPA, and my other Dell Venue 8 Pro 32GB tablet using WPA2.  Resetting the 64GB tablet now fails to initialize Windows since an internet connection is required, so I cannot perform the setup.  Back it goes to Costco Monday morning just like the previous one.  At this point I'm keeping my 32GB Venue 8 Pro since the WIFI is solid from day one and it's stable.

Could it be your 64GB models are (or originally were) devices for the Chinese market?

As far as I know, WAPI is a Chinese Mainland only wireless security protocol (required by Chinese authorities to be installed on all devices operated in China). My US market 64GB Venue 8 Pro did not come with WAPI installed. The wireless encryption methods available on my 64GB model are exactly those you see on your 32GB models.

You might be able to just un-install the WAPI components (they are an optional download on Dell's support page for my Venue 8 Pro) and see if that improves things.

I have the same problem with 2 brand new Dell Venue 8 Pro 32GB.  I tried one out of the box, and one with all updated drivers -- same challenge.  It does look like it's related to connected standby but I've had cases where I was browsing then it simply stopped.  I can see other SSID so the adapter's still available.

 

 I have a DLINK and a Cisco router -- both are experiencing this issue -- but only with the Dell Venue 8 Pro -- all other devices are working fine with wifi.  Any update on possible driver updates?

Same here on the Dell Venue 11 Pro (which has the same wifi adapter and same 45425 driver, which I have uninstalled and re-installed multiple times along with the Trusted Execution driver and chipset driver and display driver). I have a Linksys E4200 wifi access point, but I have taken the tablet on two trips now where I've used it with unknown models of hotel and airport access points, and same problem. I also agree that somehow it is connected with Connected Standby not working. From another computer on the network I can see when it loses its connection, and it is impossible to wake up the connection again remotely. The tablet is set to never go to sleep - I think only the wifi adapter is going to sleep. It doesn't wake up unless you disable and then enable it, either from the charm or sometimes from Device Manager.

One difference I have from your experience is I have never seen this happen when I'm actively using the tablet. I only see it when the tablet is sitting unused for at least a half hour. But this time interval is variable and sometimes it stays awake for several hours before falling asleep.

It seems from following a couple of different forums that a lot of people are having this problem and Dell has not come up with a solution yet. A couple of people have tried exchanging their tablets for new ones, and the same problem still arises on the new ones. I hope Dell is at least looking for a solution. Maybe it will help with the Miracast problems we all are having, too.

I bought both 64GB tablets at my local Costco store, so I doubt they would be configured for the Chinese market.  Taking the second one back today since the WIFI is no longer connecting at al.  Wondering if it's worth the hassle of trying yet a third device.  I Really would prefer the 64GB even though my 32GB tablet is stable and has solid WIFI.  I certainly do not plan on contacting Dell support and living through the offshore shuffle.

User MaximeB just reported similar WIFI issues with two 32GB tablets, so maybe it's not a difference in the mother boards or Dell WIFI adapter.

MaximeB.  Can you please check the Security setting and available Security Type and Encryption Type values on your 32GB tablet's WIFI connections?

Access the info by selecting: Control Panel > Network and Sharing Center > Change Adapter Setings > double click the WIFI connection > select Wireless Properties > Security tab.

Is the current setting WPA2-Personal? or WPA-Personal?  Are both options listed in the drop down?

Is the encryption type AES? or TKIP? Are both options listed in the drop down?

Thanks

I'm currently traveling for a few days but I'll check with someone at home tonight.  If I remember right, it's WPA2-Personal with TKIP+AES (or just AES)

 

Is this for troubleshooting or is there a preferred settings to have?

 

note: right now, at my travel location, it's using WPA2-Enterprise with AES.  it's been running fine for 2 hours, including some time that it should have gone on connected standby.

Ajdellaj, not sure if it is useful for you to know this for a 64GB Venue 11 Pro, but I followed your instructions and the answers on this device are:

Security type is WPA2-Personal. WPA-Personal is not available on the drop down. The other options listed are No authentication, WPA2-Enterprise, 802.1X, WAPI Certificate, and WAPI Shared Key.

Encryption type is AES and this is the only option offered on the drop down.

Thanks PAULINBELLVUE. That matches the available WIFI security options on my 32GB tablet that is working perfectly with 100% signal and no dropped connectivity, even after sleeping for hours.  It wakes up and is perfectly connected to WIFI.

I read that Microsoft dropped the WPA security options from Windows 8.1.  Maybe Microsoft has now put the WPA security options back into Windows 8.1, and broke the software in the process of doing so.

It seems that the tablets configured with the additional WIFI security options including WPA-Personal may have a different version of Windows 8.1 installed out of box.  Dell drivers don't seem to make a difference.   I'm leaning toward trying a third 64GB tablet and taking it to a place with a different WIFI  than my home(Starbucks or the library), set it up there and see what WIFI options are used to connect, and what options are listed.

Does anyone know if there is a way to interrogate the available security and encryption options in Windows 8.1 while there is NO WIFI connection?  So far I can only get to these settings when a WIFI connection is active, which is apparently normal.  My brand new Dell XPS 8700 with Dell 1703 wireless adapter running Windows 8 behaves the same way.  The WIFI connection must be active to see the available security and encryption settings.  The XPS 8700 shows ALL security options available and connects perfectly using WPA2-Personal and AES.

All this talk about Wifi connecting issues but I hear NOTHING about the radiation problems with it ???

Have you tested your unit ??

I tested my Ipad 8 & it pulses out every 6 to 10 seconds & some times with a double pulse.

It reads at levels up to 11,000 uW/m2 with wifi on  !!!!!    My cell phone when in use reads ONLY about 5 to 121 uW/m2 .

That's almost 100 times greater radiation levels & at almost a constant output while you use that IPAD.

I became dizzy & nauseated within 5 minutes of being near it. I bought these Ipads as gifts for my grand kids but will in NO WAY allow them to use them & will now return them. Do you know what damage or harm you will be doing to yourself or your kids ??  Google "Dangers of Wifi".
