    Intel(R) Centrino(R) Wireless-N 2230 cant go over 30MBps

    NaGeL Bailey

      I have a Dell Inspirion 5520 that has Intel(R) Centrino(R) Wireless-N 2230 built in.

       

      Also I have a TP link TL-WR740N wireless router.

       

      I have an 80Mbps/25MBps internet connection.

       

      My Speedtest result with no router:

      When I connect all these via an Ethernet cable, I get the maximum  even through the router:

      But when I try to do the same with WiFi I get 30/20 Maximum speed, and I'm sitting next to router!

      I have this configuration:

      *router:* 

      - Channel: auto 

      - Mode: 11n only 

      - Channel width: 40Mhz 

      - Max Tx rate: 150Mbps 

      - Enabled Wireless Router Radio 

      - Enabled SSID Broadcast 

      - Security: WPA- AES 

      - Beacon Interval : 100 

      - RTS Threshold: 2346 

      - Fragmentation Threshold: 2346 

      - DTIM Interval: 1 

      - Enabled WMM 

      - Enabled Short GI 

       

      *Intel(R) Centrino(R) Wireless-N 2230:* 

      - 802.11n Channel width for band 2.4 : Auto 

      - 802.11n Mode: enabled 

      - Ad Hoc Channel 802.11b/g: 1 

      - Ad Hoc QoS Mode: WMM enabled 

      - Bluetooth(R) AMP: Enabled 

      - Fat Channel Intolerant: Disabled 

      - Mixed Mode Protection: CTS-to-self Enabled

      - Roaming Aggressiveness: 3. Medium

      - Transit power: 5. Highest

      - Wireless Mode: 802.11b/g

       

      I do get the fact that speed through wireless is slower than with wire, but losing 50Mbps is a bit too much!
