Network Dropout (intermittent and consistent) - Dell Inspiron 7347, Win 8.1, Linksys BEFW11S4, Intel dual band wireless AC 7265 adapter

Jump to solution

The story: I just bought a Dell Inspiron 7347 tablet/laptop (exchanged for another unit, see below).   Having issues maintaining a solid network connection and when it is connected, it's very slow.   When connected to the wireless router, it holds a connection (slow) for about 3 - 5 minutes and then craps out (limited connection with the yellow "!" over the wifi signal in task bar).  It then comes back up 1 - 3 minutes later.  It's a consistent ongoing cycle.  I've tried resetting the router to factory defaults with no luck.

All other devices on this router (desktop, phone, IPad) all hold the connection no problem at the same time this unit doesn't.

Notable:   Before I bought this tablet/laptop I had bought an Acer Aspire tablet/laptop that had the exact same issue on my network.  I returned that unit for other reasons (build quality etc) but it had the same OS (Win 8.1).  I don't know if it had the same network adapter installed.  

What I've tried:  Cycling the router - Cycling the modem - Resetting the router to factory defaults - Disabling U-APSD on the network adapter - Slapping myself hard - Offering small animals to the gods...

What I tried to try:  Attempted to update the drivers for the Intel adapter using the Intel Driver Update Utility ( Intel PROset wireless adapter and drivers for Win 8.1) but it kept timing out during download because...THE NETWORK ISN'T STABLE! (ugh!) 

The setup:

Dell Inspiron 7347
OS Win 8.1 all updates run

Network adapter: Intel dual band wireless AC 7265

FIXED!!!   Check it out guys.   I was messing about with turning off all network card resources, add-ins etc in hopes of narrowing this down...including Bluetooth.   I have a Microsoft Bluetooth Sculpt Comfort Mouse ( [View:www.microsoft.com/.../sculpt-comfort-mouse:550:0]  )

I turned it off and BOOM...all was fine.   I noticed also when it was on, the speedtest would dip dramatically when I actually moved the mouse during the test.   See below for the test result with the mouse off.   I can't post one with the mouse on because the test wouldn't even complete with it on.

Hmmmm....so it turns out it could be a problem with a MS product...go figure.

I don't think so. I have a same problem but I think the problem is Dell Bluetooth not MS product.

when you enable Bluetooth  your wireless speed will slow down.

This is my testing by use wireless network copy file 350 MB from my computer desktop to my laptop Dell 7347

Bluetooth off  : Speed 11.4 MB/s (very fast)

Bluetooth on  : Speed 710 KB/s (very slow)

I want Dell update wireless driver to solve this problem.

The date on the firmware for your router is 2003. And it's a B router. You might just want to upgrade to something newer. Just a thought. I just got done dealing with the exact same scenario but with my desktop. The Internet tech came out and checked my lines and wireless router and then he made a note of the exact times my system was dropping the connection. He then went and looked at some of my neighbors on his laptop and could see there were 5 other customers of his that were dropping their connections at the exact same time to the seconds. He was able to follow it up the line to determine the problem was originating in their hardware on one of the poles a few blocks from here. He put in an order to send out the line repair guys to replace a switch or something and wala! I very seldom drop any connections anymore. My laptop got its Intel ProSet drivers updated from the Dell site. Didn't care for the Intel update utility. I wish I could give you more info on that but my laptop got stolen on thanksgiving so I can't refer to it and give you the latest driver info. Sorry. Good luck with this. It really is a maddening situation and I can empathize with you,

Thanks for the input.   You're right.  It is an old router.  Perhaps I'll try a newer one.

Sorry about your laptop.   Some people just suck (but not all).

UPDATE:  Tethered to my phone and got the driver updated.   Still not fixed 😞

I'm having the exact same problem with a 7347 purchased four days ago from Microsoft store. I have a less than year old xfinity router and all other devices in the house reach the 30 down 5 up consistently while this 7347 is lucky to get anywhere close to that.

I bought my 7347 a month ago and have the same issue with my dell 7347 and Zyxel Keenetic Giga. 

Connection fails after ~half of hour. Yellow flag appeared at network icon. It should be reconnect.

Other my wifi clients (tvs, phones, notebook) work fine.

My wifi driver version is A00.

Need help...

I bought a new wifi router ( [View:us.dlink.com/.../:550:0] ) 

Still having the same drop out issue.   Using all default settings on the router.  I am also now starting to see drop outs on my work network also.

Contacted my service provider (Time Warner) and had a chat with a tech who seemed to be helpful.  

Below is the content of the chat but it shoudl suffice to say she remoted into my PC and set the router settings as she indicates at the bottom of the chat.  I'm testing connection now.   If you don't hear anything more, it's save to assume that it worked.   Here's hoping 😕

I have changed the settings on your router page which was blocking to get the access to full speeds.
Kevin Lucas: at 19:12:12
Can you tell exactly what you did? I have a blog post at the Dell forum about this and there's a number of people who might really be helped with this info?

Your Bandwidth settings was set to auto which I have set it to 20 Ghz and changed the signal strength to max.

I've been trying this and it seems to be working as I've noticed speed drops considerably when on battery. Default seems to be Maximum Power Saving. Power Options>Change Plan Settings>Change Advanced Power Settings>Wireless Adapter Settings>Power Saving Mode>On Battery>Maximum Performance.

Give it a shot. Post back if it works or not. Hopefully it does otherwise we're going to have to dig further. Not sure how nobody could have noticed this issue until now.

I'll try this right now.   Thanks for the suggestion 🙂  I'll let you know how it goes either way.
