Please note that Daniel reported that his problem was solved after he flashed 1.5.6 into the Teletronics card.

I have a similar problem with a different setup.
I am running wisp-dist on a microATX with 2 senao cards with adapters and one wmp11.
On the other side the client is a DLink DW-900AP+ pointing to one of the senao cards.
Cables are 1.5 meters of LRM-240 in each side and antennas are 15 dBi yagui against 12 dBi diedro, distant 600 meters from each other.
Sometimes the association drops and then re-associates again by itself, but sometimes it remains disconnected and I have to reconnect them by hand.
It may be working ok for weeks but sometimes I have to recopnnect by hand twice or three times in the same week.
In any case, how has to be configured the AP or the router to minimize (or eliminate, if possible) these dropouts?
Thanx in advance.

Hi,
Does the second access point have the same ESSID? Then it might be the problem.
Otherwise, I recommend to flash the 1.5.6 firmware on the Teletronics wireless card.

I have a Soekris net4521 running Wisp-Dist, using a single Teletronics
200mW pcmcia card attached to a 12" pigtail and a 15db planar antenna.
It is operating as a single access point. I am using a standard 12v
power supply (purchased with the board from Soekris) which feeds through
the power input jack (not POE).
Access is via a Toshiba laptop also running a Teletronics 200mW pcmcia
card with one of the little pigtail whip antennas. The laptop can boot
WinXP/Fedora Core 1/FreeBSD 4.9.
I get strong reception in many parts of the building and everything seems to work well . . . except that the signal drops out every so often without warning. Sometimes it is able to reconnect on its own, while atothers I have to manually reconnect. It happens when I am at the outer limits of the access point's range but also when close by (i.e., in the same room).
The /etc/network/wireless.conf is as follows:
# Wireless configuration parameters # netcs0_MODE="MASTER" netcs0_ENCMODE="ON" netcs0_RATE="11M" netcs0_ESSID="fpcwireless" netcs0_KEY="##:##:##:##:##" <== not actual netcs0_CHANNEL="11" netcs0_MACFILTER_POLICY="0" netcs0_NICK="fpcwireless1" netcs0_TXPOWER="200mW" netcs0_RTS=""
With no wireless clients connected, iwconfig displays the following:
netcs0 IEEE 802.11-DS ESSID:"fpcwireless" Nickname:"fpcwireless1" Mode:Master Frequency:2.462GHz Access Point: 00:02:6F:05:59:2F Bit Rate=2Mb/s Tx-Power=24 dBm Sensitivity=1/3 Retry min limit:8 RTS thr:off Fragment thr:off Encryption key:####-####-## Encryption mode:restricted Power Management:off Link Quality:0 Signal level:0 Noise level:0 Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:90 Invalid misc:269 Missed beacon:0
I have not configured RTS/CTS as I am not sure what those settings ought to be.
I do not know if my problem is due to hardware/software/local interference or something else. I do have another lower powered (30mW SMC) AP in another part of the building running on channel 6 with a 6db antenna, but that does not seem to be a problem.
I am concerned that the problem is related to the hardware, but have not the expertise to diagnose it. Any suggestions where I should begin?
