I found this thread while trying to determine why I get such poor performance here with the following equipment and configuration:
Lenovo R400 laptop with Windows 7 Ultimate
Intel WiFi Link 5300 with Intel driver version 220.127.116.11
EnGenius EAP350 with firmware version 1.2.2
Wireless Mode: 802.11 B/G/N Mixed
Channel HT Mode: 20/40 MHz
Extension Channel: Lower
Channel/Frequency: Ch 11-2.462 GHz
Security Mode: WPA2-PSK
Transmit Power: 25 dBm
Distance: 1 km
The laptop only connects at 130 Mbps and a file transfer to a Samba share on a Linux host only achieves appox. 1.5 MB/s. I know the WiFi Link 5300 is capable of faster connections and higher throughput because I get it on other networks with different types of access points, similar to what the original poster described.
I changed some of the settings on the EAP350, as follows:
Wireless Mode: 802.11 N Only
Channel HT Mode: 40 MHz
After save/reboot, the laptop now connects at 300 Mbps and the same file transfer yields approx. 3.5 MB/s. Using an ASUS RT-66U in place of the EAP350 yields no issues with connection (in fact, I can connect in the 5 GHz band as well, which I know the EAP350 does not support), but even connecting on the 2.4 GHz band, I still get transfers that average in the 7-8 MB/s range. I know there are no issues on the server side in regards to the file transfer, as a wired network connection from the same laptop to the same Samba share yields just under 100 MB/s transfer, which is being limited by the gigbit interface in the laptop.
I had decided to switch away from consumer routers and access points, but I am presently very frustrated with my experiences thus far with this access point. I would really appreciate some guidance on how best to configure my EAP350 to achieve better results.
Thanks in advance,
