We understand that your computer is showing a slow wireless connection. This type of behavior can be caused by different factors, here are some initial recommendations for this:
- Install the latest driver provided by the Computer Manufacturer Support. Or you can also try the generic version of Intel® PROSet/Wireless Software and Drivers for Windows® 10* [19.60.0].
- Apply the configuration mentioned in the following document: Recommended Settings for 802.11n Connectivity.
If the issue persists, please provide the following information:
- Download Intel® System Support Utility, run the tool and use it to create a report with all sections, once the report is created, click on the "Next" button. In the following screen, save the report to a file. Then use the Advanced editor options of the communities to add the resulting file to your post as an attachment.
- Access point model and firmware version.
- What is the download/upload speed you expect to see? and which method are you using to test the speed?
- Has the connection worked fine before?
Hello Jonathan B.
1) Install the latest driver - done, version 188.8.131.52
2) apply Recommended Settings for 802.11n Connectivity. - done
3) run the Intel® System Support Utility - done, the report in the attachement
4) access point - Cisco AIR-AP1852 (OS version 10.3.141.0)
5) upload speed - 110 Mbit/s, download speed 200 kbit/s - same results on different modes (2,4GHz b,g,n and 5GHz n,ac)
6) on the old laptop (Lenovo x240) with wifi N7296 no issue - the speed about 100Mbit/s on both direction.

We checked the log and the information looks normal for your configuration, the adapter is using 802.11ac with 144.4 Mbps connection rate:
Radio Type: 802.11ac
Receive Rate: 144.4 Mbps
Transmit Rate: 144.4 Mbps
Signal Strength: 99%
We would like to mention that the difference you get between download and upload is very significant, so there may be an issue in the network. Here are some additional actions for you to consider:
- Engage the network administrator and look for any bandwidth allocation feature that may be limiting the connection.
- Contact Cisco Support and check with them about this as well.
From the adapter side, here are couple actions that may improve connectivity, even though they may not account for the difference of 110 Mbps Upload vs 200 kbps Download:
- Disable the Bluetooth* component of your wireless adapter, this is normally done with a hardware switch in the PC, or with a key combination, it can also be done within Windows* settings.
- In the advanced driver properties, try enabling U-APSD support. As it may work better with newer Access points. You can disable it again if there is no improvement.
U-APSD support: Enabled
We are glad to know the issue was solved. We are sure this information will be very useful for any other users facing this situation.
