Hi gents,
just updated my driver to latest one - 18.33.9.3
win 7 x64
the problem:
link is flapping when under load if bluetooth is running
my wifi card is able to drop and establish connection every 30 secs - unusable !
turning bluetooth off is a workaround here, but hey .. Intel ! I am disappointed ...
I will either downgrade or turn BT off or any other ideas to try ?
other devices at home are completely OK ...

Hello Phoenixx,
Is this adapter the one installed by the manufacturer? Could you please inform the make and model of your system?
Have you tried the solution found here: /message/491240# 491240 noted previously by NoNewbie. We are going to branch your question as it involves Bluetooth* and this discussion is about the VHT which is related to 5.0GHz connectivity.
Bluetooth* and wireless share the same antennas and the same frequency 2.4GHz, that means that Bluetooth* connectivity can cause interference with the wireless one. Try to change the channel to one that is less crowded. The alternative is to use the 5.0GHz band to avoid interference caused when Bluetooth is active.
Best regards,
Aleki

Hi Aleki,
yes, it is installed by manufacturer - HP EliteBook 820 G2. I will try to downgrade the driver back to either my old version of Intel driver or MS provided one ...
PS: using 2,4 GHz router only ... not sure if it's applicable also for this setup ...

Phoenixx,
Since this adapter is an Original Equipment Manufacturer also known as OEM, the best recommendation is to use the drives recommended by it and in your case it is an HP's. For your convenience, here is the link to the OEM drivers:https://support.hp.com/us-en/drivers/selfservice/hp-elitebook-820-g2-notebook-pc/7343192 HP Customer Support - Software and Driver Downloads

Phoenixx,
Usually the Bluetooth* to turn off, if not necessary, is the one on your computer.

Hi Carlos,
I am sorry for this, but as the affected notebook is a company device, it's not easy to obtain admin rights to either change the driver or run the tool suggested previously.
I'll try to speed this up & post the results asap ...
thanks ...

hi gents,
today I updated the driver to latest one - from Nov 20th, the behavior is slightly different.
Link is not flapping that much - only few drops. But download speed is cut to half - with bluetooth turned on (imagine I have to work on wifi network with BT headphones ON)
If I will turn BT off, everything will come back to normal - full download speed, no flapping.
Turning off VHT mode is also not an option here.
I will try to collect system logs via SSU tool, then I will check if I could post it here.
Only way for now is to rollback to driver from few years ago where this issue was not present.
Thanks.

Hello phoenixx,
- Do you have the option to enable Bluetooth® AMP in your adapter settings?
- What is the brand and model of your wireless router/access point?
We look forward to your SSU report. To enable attachments, make sure to switch to the advanced editor while replying.

Hi Carlos,
first - yes I have BT AMP mode enabled, if BT is disabled, link is ok, if BT enabled - link is flapping is a little bit ...
with AMP disabled - it's even worse ... link flapping each 8 secs ...
I did a rollback to driver from 2014 - v 17.13.0.9 - absolutely no issue if BT is on or off ... no link flapping or performance issue ...
next - my router is from ASUS - RT-N18U - with latest official firmware.
last - this is my company device so I am limited in providing logs to you, could you please specify what logs from SSU would be helpful for you ?
Thanks a lot !

Hello phoenixx,
The SSU report won't include any personal identifiable information, only your system specifications, settings, driver versions, etc. This report is the simplest, but not the only way to get what we need. We definitely do understand how company policies may get in the way of this sometimes, that's OK.
We'd like to have the following information:
1. What is the model of your wireless adapter?
2. Which version of Windows 7* are you using? (example, Home Premium 64-bit, SP1).
3. We understand the issue is being triggered by an update to your Wireless driver. Which driver version are you using for Bluetooth®?
Best regards,
Carlos A.

Hello phoenixx,
Thank you for this information.
The Bluetooth® module is integrated into one of our wireless adapter. In device manager please look under Network Adapters and provide us the name of the wireless module showing there.

Hello phoenixx,
Please confirm that you're using the latest drivers for your wireless adapter:

We're currently checking with our additional resources to see what changes where made to the latest Bluetooth® driver that could be resulting in your performance issues, and any possible workaround.

Hi Carlos,
yes, I was using also latest driver you've mentioned for my AC7265 - the issue was less appearing, but still there.
Therefore I had to roll-back to driver from 2014 - as mentioned in previous posts - as effective workaround.
