I have an Issue with my Fortiwifi 60C, wireless performances are just horrible, with Wifi N (at 2.4Ghz), without any filter (permit everything, no utm, no ips, no av, no logging), I never get something better than 1.7MB/s (to a local server on the internal interface)... It' s just unusable.
What can be the cause of this ? How to fix this ? I' m running FortiOS 4 MR 3 patch 8.
CPU gets really high when I try to transfer something between internal interface and wireless interface.
Switching from AES+TKIP to AES and disable Rogue detection improved speed up to 2.5MB/s
Here are the 2 most consumming process during data transfer:
Please try using 5Ghz. FortiOS 5.0 has wifi performance improvement for local Radio. You need to enroll for Beta program to try FortiOS 5.0. In WFA testing, FWF60C performaced very well with throughput of more than 80Mbps.
