Thanks for posting in our community. We understand you're experiencing slow wireless download speeds on your laptop.
It seems unlikely to be a driver related issue since the issue happens with both the Intel® Dual Band Wireless-AC 8260 and the USB wireless dongle. Each devices uses different drivers.
It is possible an application or operating system service is blocking or consuming the bandwidth. However, we would to confirm your system and network specifications to confirm if there's anything we can do to improve the connection quality:
- Intel® System Support Utility report.
1. Download the latest Intel® SSU.
2. While connected to your WiFi network, run the scan. Select to include "everything."
3. Name and save the report.
- Your WLAN Auto-Config log.
1. In the search box on the taskbar, type Command prompt, press and hold (or right-click) Command prompt, and then select Run as administrator > Yes.
2. Enter: netsh wlan show wlanreport
3. Go to: C:\ProgramData\Microsoft\WlanReport\ locate wlan-report-latest.html
I faced the similar issue on my brand new hp spectre laptop.
I did the wireless network report as you suggested and it shows that the main disconnect reason is "the network is disconnected by the driver".
Download throughput was doing well when I got the computer ie 30 Mbps and now I strive to go beyond 1 Mbps.
Any suggestion besides taking a look to the report ? Why would the driver disconnect from the network by itself ?
Thanks for posting.
The driver installation may be corrupted. We recommend performing a clean driver installation as instructed here:
Please notice that the article mentions there are three different drivers you can test. The Intel generic driver, the driver provided by the OEM (Original Equipment Manufacturer) and the inbox driver installed by Windows*. Please let us know the results.
