Intel 7265 adapter leads to BSOD (netwtw02.sys) in mesh wifi network

At my office we have a mesh wifi network (e.g. multiple accespoint broadcasting the same SSID name). However when I walk around with my Dell windows tablet windows 10 crashes when it gets connected to a different accesspoint. The BSOD is in netwtw02.sys.

Updated many times my wifi drivers, even to the latest beta drivers. Installed the PROSET software (also updated this several times to latest version) but it keeps having this problem. Also reset my tablet twice the couple of last week and even that didn't help.

I now put my tablet to sleep before going to another site of the office building, which works most of the time, but 1 out of 10 still leads to a crash when awake from this sleep. My tablet literally crashed 50-75 times the last couple of months. Last weekend I reset again my tablet, and today I had my first two crashes already. Unfortunate my job requires lots of meetings in different meeting places.

Note: using certificates to connect instead of loginnames. The access points are not visible (behind the roofs), but I think they are Cisco ones. I also checked and unchecked the box 'cisco settings - enable radio measurement' in ProSet. Also played with band selection mixed band, 2.4ghz or 5ghz band only but nothing helps either (other then on the 2.4ghz band I get a 144mbs and on 5ghz I get al 300mbs connection performing very well).

Anybody having a solution?

xavalon,

Regarding the wrieless adapter, could you tell us what driver version you were using?

Does this issue occurs only with this specific network?

Have you check for any possible BIOS updates?

Is this occurring after an update?

Could you send us the dump files?

My Dell Venue 11 Pro tablet (7140 model) is updated to the latest bios

Running Windows 10 Pro - 64bit; latest updates via windows update. Installed McAfee livesafe. The tablet was imported from the USA, but is in use in the Netherlands.

Current wifi driver version is 18.30.0.9 (3 november 2015). Good performance both at work and home.

The BSOD/crash (in netwtw02.sys) occurs only at work, not at home. Rarely use my tablet elsewhere then office and home. I get the crash as I get connected to a new access-point There are many access points in our office (large building). We use client certificates to connect to the wifi network. I tried several driver versions in recent months, also resetted windows 10 twice but the BSOD is there again immediate. Today it crashed again.

I can recall that I had access to another SSID using a personal login+password and didn't have those issues. This wifi network was dismantled this summer and was only available in a small part of the office but had a desk there.

Yes I might be able to send the dump files but please assist how.

I noticed my system has been crashing frequenly for the past few days. BSOD (netwtw02.sys).

In addition. I notice that browsing the internet speed seems a little slower too.

Please intel, release new driver to fix this.

I have to plug my laptop to Ethernet to prevent system crashing.

khoaiii,

Which drivers do you have currently installed amd what is your OS? Intel recommend that you check with your computer manufacturer first in order to obtain the latest drivers.

As a second option, you can try the generic drivers found in our dowload center for this wireless adapter: https://downloadcenter.intel.com/product/83635/Intel-Dual-Band-Wireless-AC-7265 Drivers & Software

i was running with latest driver 18.30.0. BSOD and I have to downgrade to 18.21. My system is running fine with 18.21. Please fix your 18.30 driver.

I find the 18.30 version is better than the 21, but the blue screen probability is become much less, but it still exists.

I used a workaround and that is shutting down windows and rebooting again when i relocate in the office for the next meeting. Then i never had a crash. Only when getting out of sleepmode and changed location in the office building it occurred. This however occurs minutes later after leaving the sleepmode, not immediately. Also most of the time, not every time (say 8 out of 10 i got this BSOD).

I installed the latest Wifi Drivers version 18.32.0.5 (dated 22 december 2015) a few days ago, and they look more stable and didn't give me a BSOD yet.

They are labeled WHQL so no beta. But i downloaded them from another website then intel. Google is your friend.

Aleki,

thx but for now it is working and don't experience a BSOD anymore. Think the newer drivers fixed it for me. I will come back if I again experience BSOD's.

Just upgraded to PROSET 18.33.0.1 WHQL to see if this version is also stable.

Version 18.32.1.2 WHQL was very solid for me, and I didn't experience any bluescreen-of-death in a meshed WiFi network anymore. Sometimes I get disconnected and have to connect manually but that's all.
