Laptops keeps roaming when signal strength is 90%

Hello,

we have a some problems with wifi roaming. Wifi adapter roaming no matter if signal strength is excellent or not. Roaming agresivity setting have no influence on this behavior.

Do you have any experience with this behavior or any suggestions what could be root cause of this issue? Am I able to find some detailed logs in Windows, which can describe why network adapter roam to different AP?

Thanks in advance,

Jan

Hello dvorskycz,

 

Thank you for contacting our community forums.

 

In order to assist you, please go ahead and uninstall all the current drivers (even if you already have the latest ones) and install them again by following the instructions on this link:

 

https://www.intel.com/content/www/us/en/support/articles/000022173/network-and-i-o/wireless-networki...

 

Here is the link for the latest drivers:

As well you may want to try our Recommend advanced settings available at:

We recommend you to lower the Roaming Aggressiveness to lowest or low-medium and then monitor the results.

 

As well, please access your router and make sure that you do not have any QoS (quality of service) active on it.

 

 

I hope to hear from you soon.

Hello Diego,

I tried install drivers from laptop vendor (HP) and newest Intel drivers as well, without any change of described behavior.

Also, I didn't found any advanced settings which had any influence on it (it was still same when Roaming Aggressiveness was set to highest or lowest).

The most strange thing is that this problem is not persistent. This is a reason why I want to find reason why network adapter started roaming - is there any log where I can see something like "Low signal, adapter started to roaming to different AP"?

Just to be clear - I need to tell if problem is caused by client or by network itself (for example by some interference for a short time).

Thank you for your help,

Jan

Hello Diego,

this issue is related to our enterprise environment.

Since we tried almost everything on endpoint devices and we are solving it with MS, HP and Cisco, Intel is a vendor of network adapter so I bet you could have a best options how to get some information from it.

How I already wrote - is there any possibility that I can see a reason why network adapter was disconnected from AP and doing a reconnect? Cisco saying that connection reset is from client site but we cannot find a reason why? Signal strength is ok and problem is related only to Windows devices only. It looks like client is reconnecting fifteen times per twenty minutes (even on the same AP) and then connection holds for an hour and so on.

I need to know what is the reason of that reconnects (since we have a complex environment, any logs or monitoring tools, which we can use, will be very appreciated).

Hello Diego,

we already found resolutions of our problems. Roaming behavior is still a mystery. If you can share with me any details how it's works... It's only about signal strength or there are another things which matters?

Thank you for your help,

Jan

Hello dvorskycz,

 

Thank you for your response.

 

In this case, roaming should be only used on enterprise environments, most issues with that would depend on the infrastructure and not on the actual hardware.
