Please check if you have widest channel selected in the wireless adapter properties for 5GHz.
I looked at the settings for my router and adapter, on the adapter the 802.11n channel width is on auto, and on my router I put the settings I saw to maximum, but have not seen any change. The settings I have for my adapter are as followed:
802.11n channel width 2.4ghz- auto
802.11n channel width 5.2ghz- auto
Adhoc Channel 802.11b/g- 1
Adhoc QoS mode- WWM enabled
ARP offload for WoLAN- Enabled
Bluetooth AMP- Enabled
GTK Rekeying for WoLAN- Enabled
HT Mode- VHT mode
Mixed mode protection- CTS-to-Self enabled
NS offload for WoLAN- Enabled
Preferred Band- Prefer 5.2Ghz band
Roaming Aggressiveness- Medium
Sleep on WoWLAN disconnect- Disabled
Transmit Power- Highest
Wake on Magic Packet- Enabled
Wake on Pattern Match- Enabled
Wireless Mode- 6. 802.11a/b/g
Is there anything that looks wrong or needs to be changed? Thanks
And what speed do you get if the AP is set to 802.11n only?
Thanks for the help, but I do not require assistance anymore.
Throughput depends of many factors like electrical noise and interference, AP configuration and drivers.
I am sorry for any inconvenience.
