Dell Venue Pro loses wireless connection after installing Windows Updates

Try shutting down using the windows 8.1 start button shutdown instead of the settings charm. It seems to provide a workaround.

After a couple of days experimenting, I am able to control whether or not the WiFi goes into Limited connection when the Venue has been shut down.

If I shutdown the unit through the Charms menu, it will not reconnect to my wifi when powering on.

BUT, if I shutdown using the "Start" button menu, the Venue will connect completely to the router even if the tablet has been off over night and NOT plugged into the charger. It also works if the Venue was plugged in.

Why should there be this difference and does this constitute a valid workaround for the WiFi issue?

what do other people find?

Charm and "start menu" are the same... o_0 That doesnt make sense what you wrote. Also, what do you mean by shutting down? Hibernate? Complete off? You should disable hibernate (powercfg -h off) and just use the "connected standy" mode, my Venue has a battery discharge rate of 0.37% per hour in connected standby mode, and that's good for me.

Also, Ive tested into this problem again, and it's totally clear for me: It is working without any problem with 2,4ghz b/g mode. And the problem just happens with N mode, both 2,4ghz and 5ghz. If you set your router to just use b/g mode (55mb/s), it stays stable. If you activate N mode, the Venue becomes instable at some point (limited connectivity aka no internet, but it is still connected to the router).

Thanks for the reply and I agree with you that it shouldn't make any difference how you issue the shutdown command (to clarify, I was doing a complete shutdown not just sleep or hibernate.) which is why I was interested in whether other people could replicate the behavior. As I said it appears to be just a workaround and not a fix.

Thanks for the heads up about the N wireless setting but, in my case, I only have a G class router so it doesn't apply in my situation.

The only thing that leads me to suspect that the different shutdown buttons do different things (crazy I know) is that the perfect predictability of the two shutdown methods. I know what will happen to the wifi depending on how I shutdown. 

I remember there used to be an issue with the original Surface RT when shutting down. The system would be in Mute when powered back on. A patch fixed that. This has the same feel...but let's see if it happens for anybody else.

No they dont do different things, and shutdown is something complete different than Hibernate or Sleep... And saying "do a shutdown and it fixes it" is complete nonsense, of course it will fix it for a short time o0 because it will reconnect/load drivers new. It's same as deactivating wifi card and activating it again (no, not over the wifi slider in metro ui, but in the wifi adapters list). Like I said, the dell drivers are b***s***, like the Intel drivers were some time ago (google intel 6235 connectivity issues). If your router really just has b/g (54mb/s), than still it can be the reason and you should get yourself a new one running OpenWRT for example.

Also: bluetooth doesnt work correctly if you use 2,4ghz with the Venue. My bluetooth mouse lags and becomes instable. If you switch to 5ghzt it is working.

Well, for me, this is a viable workaround so I just put it out there in case it might be helpful to somebody else. Thanks for replying.
