Hey Tom, https://www.intel.com/content/www/us/en/download/19779/intel-killer-performance-suite.html
Have you tried the above "Killer Performance Suite for the 7590's.Also, are you running your APX units in the Central Wireless platform or managed from the Firewall? Are your channels setup to avoid any local interference? Leaving the AT&T WiFI off would be best to avoid introducing 5GHz interference into the environment.Are you using TKIP on any of the SSIDs? If so, consider switching over to AES.Sorry, lots of questions!
Thank you for the reply!
1 - Regarding Intel Killer Suite - Yes I tried installing those drivers and did not make any difference.
2 - I manage the APX units from the XG Firewall directly -
3 - AES (Secure) is selected for encryption
4 - Normally the AT&T is disabled, I enabled it just to test the laptop against another WiFi AP
I am moving the Access Points to the Sophos Central tonight. I need to register them while they are initializing. Apparently, Sophos Central has more controls for the APs.
There is a firmware upgrade to apply also 11.0.015 (I am on 11.0.9)
Sophos support logged in remotely and looked around. They moved the firewall rule for the Private WiFi from further down the list to the top.
My Macbook gets 200Mb/s up and down and the Dell 7590 now is getting 15-20MB/S down/up - usable.
Tom, when you move them to Central, the firmware is handled automatically, and APX units are kept up to date on a schedule by Central. Interesting about the firewalls rules, possibly a rule above it was misapplying QoS, glad you are up to some speed now though!
