Hello list,
I am running the 4.9 release of FreeBSD on an embedded net4521 box
and my problem is:
Recently a wireless ISP put up an antenna in our apartment complex.
Now for some reason, my 4521 (and my iBook with regular AirPort, also
BSD based??) favor the wireless ISP's connection over my own LinkSys
access point. The ISP's antenna runs on channel 1 and consistently
has a stronger signal than my own AP (channel 6). I have tried changing
my own AP's channel to no avail.
Each time I issue the commands to associate with my AP the 4521 merely
connects to the ISP rather than my specified SSID. If I check wicontrol
or ifconfig it reports that the desired netname is my AP, but the current
netname always ends up to be the ISP's AP. This is extremely irritating.
I recently got a wireless card (NL-2511CD Plus EXT2 802.11b PCMCIA
by SENAO) w/ the prism 2.5 chipset, and the aforementioned problem is
only with this card. My older card (a 3com 3CRWE737A PCMCIA) works
*relatively* well, but I wanted to upgrade so...
Has anyone had this problem, and does anyone have a suggestion to fix it?
Any insight into the BSD or the OS X problem would be greatly appreciated!
Thanks.. Tyler
