** Intel Centrino Advanced N 6205 slow internet speed **

Hello -

My T430s Lenovo Thinkpad consistently taps out around 94-95 mbps (per speedtest.xfinity.com) while 5 other devices (ipad, android phone, iphone, 10 year old HP DV7 laptop and Lenovo Thinkpad W540) consistently test between 160-175 mbps.

Current driver installed is 15.18.0.1 (4/30/2015), which shows to be the latest available from Intel through website and driver update utility. N mode is enabled. 5.2 is preferred band. Roaming aggressiveness is set to 5 - Highest (have tried all settings, this gives me the best speed). Transmit power is set to 5- Highest. Wireless mode is set to 6 - a/b/g. Obviously not a router issues since my other devices dont have the same problem. The device with an issue and 2 other devices sit in the same room, basically right next to each other. I have also disabled the 2.4 hz band on the router. PC's power settings are set to best performance.

Any ideas??

Thanks in advance!

Sebastian

Hello Sebastian,

 

 

We understand your system is showing a wireless connection slower than other devices in the network. This type of issue can be caused by different factors and we would need more information to provide detailed recommendations.

 

 

- Please check the QOS configuration of the wireless Access Point and make sure it has "WMM" enabled for the network. Also, any access list, or priority settings must be disabled, or at least giving high priority to the PC with the issue.

 

 

If the issues persists, please provide the following information.

 

 

- Is this the adapter that was built-in from factory with your computer?

 

- Was this working fine before?

 

- Download https://downloadcenter.intel.com/download/25293/Intel-System-Support-Utility Intel® System Support Utility, run the tool and use it to create and save a report with all sections, then add a reply using the Advanced editor options to attach the resulting file to this thread.

Jonathan,

 

Thank your for your reply. QOS is not configured on the router. WMM is enabled.

- Is this the adapter that was built-in from factory with your computer? Yes, it's a built-in wireless adapter on a Lenovo Thinkpad

- Was this working fine before? No, it has always produced lesser speeds than other devices connected to the same router regardless of physical location in the house (I've moved it around). I have also compared by placing other laptop and tablet devices in the same spot where this laptop sits, all these devices tap out around 150 mbps while this one never goes over 95-96 mbps.

I recently completed a fresh install of Windows 10 with the same results. I have installed Wireless 19.1 ProSet 64 bit for Win 10, however the device driver is still 15.18.0.1. Windows says that is the latest driver available, even when uninstalled and re-installed.

I have attached SSU scan results for your review. Thank you.

Hello Sebastian,

The logs do not show any issue with the adapter that may be causing the slow performance. The adapter is getting a proper connection to the network in the 5GHz band, using 802.11n, with a Receive and trasmit rate of 300 Mbps.

Please take into consideration the following information regarding this adapter and Windows® 10:

- The Intel® Centrino® Advanced-N 6205 is not fully supported in Windows® 10, however, it may be used with the Windows* 8 or 8.1 driver. It may not work at its best since it does not use Windows® 10 drivers.

 

http://www.intel.com/content/www/us/en/support/network-and-i-o/wireless-networking/000005602.html Supported Operating Systems for Intel® Wireless Products

- The driver 15.18.0.1 is the current version available for the 6205 in Windows* 8, 8.1 and 10. Intel® PROSet/Wireless Software is the Software/driver package (current version 19.xx), but the actual driver depends on the adapter and the OS.

Since you already confirmed that the access point is not limiting the bandwidth available for this PC, here are couple of things you may want to check:

- Set the wireless adapter's power settings to maximum performance when plugged in and on battery:

 

http://www.intel.com/content/www/us/en/support/network-and-i-o/wireless-networking/000005879.html Setting Wireless Adapter Power Management

- Disable the Bluetooth* component of your system. This is normally done with a hardware switch in the PC chassis, or using a key combination.

- Disable Windows® 10 features that consume bandwidth:

Thanks Jonathan. Unfortunately, I had already disabled those features. The issue may related to the Win10 driver then.

Hello,

 

 

Since the situation remains after all the previous actions, it may not be possible to increase the speed for this connection. Please consider that this is a legacy adapter and support for it in Windows® 10 is limited.
