TP-LINK TL-WN861N card bad reception



  • Hi,

    I'm using a TP-LINK TL-WN861N wireless card in a Alix board.
    At first my machine did choke on the "N" mode, so i force it to "G".

    My reception is quite bad. Before i had a simple Linksys WRT54GL with much better reception.
    Even if i'm sitting next to the device i get not full bars.

    I tried those two antenna's (with different angle) (seperately):
    TP-Link TL-WN861N
    TP-Link TL-ANT2408CL

    Now i use two "cheap" antenna's from Ebay.
    All the same.

    I've tried to change my Region to New Zealand. So, now i can change the txpower to 30. Still the same.

    ifconfig ath0_wlan0 txpower 30

    I can't change the number in the Pfsense interface.

    Is this card not well supported in Pfsense/BSD?

    Any pointers?
