Thank you both! I've been trying to figure out what's happening, and I appreciate all the information and suggestions. Yes, I'm just trying to cover the marina. I have two 120 degree sectors on the roof of the yacht club aimed in at the marina (obviously) with a very slight down tilt (1-2 degrees). I will try increasing the down tilt and see how that goes.

I moved to the Marina in mid August and in mid September I had my T1 line and first AP in place at the yacht club (though I've only recently given them more logical ESSIDs...) I'm convinced that the interference I'm getting can not be attribute to darkersun, and it's just coincidental that I picked up one AP of theirs (DarkerSun-Touchless) for the first time at about the time my problems began.

I am running on channels 1 and 11 in vertical polarization. I'll have to get new antennas then to go horizontal...

I'm not the one that was having the problem, I just gave Scott some
suggestions since no-one else had responded to him on the list.

But your information fills in alot of gaps. Scott never got back to me, but
looking at the marina, AND if scott is using Sector antennas, the only way he
could cover the marina AND he is on the Berkley Yacht Club would be if at
least one of them was directly facing you AP's.

So that explains alot.

So, besides your excellent suggestions, if the Marina is the only thing he
wants to cover, he should introduce some aggressive downtilt into his
antennas. That should take your AP's and any others ouf of the direct beam of
his antenna but still give excellent signals to the marina. Or, alternately,
relocate the AP's and sector antennas so they point out at the bay, putting
the back side towards your antennas and the rest of Berkeley. Minimizing the
coverage area to just what you target is the best long term solution for
anyone in this situation. If it is not you, it will be someone else.

As the owner of all of the DarkerSun access points in the Berkeley
area, I can provide some data and perspective as to what the Marina
is seeing:

1) I noticed the the Berkeley marina SSIDs showing up about 2 weeks
ago..

2) All of my Berkeley AP's have been in place for over a year now..
We provide broadband internet to the berkeley and Oakland area.

3) The APs consist of 14db 90 degree Maxrad sectors setup with a
downtilt pointed at the mid-flats of the Berkeley Oakland area. We
currently have 6 high level APs in operation, they are fed at. Our
customers use 14db panels to connect into the sectors from downtown,
and the hills. All of the APs are located on tower sites atop the
Berkeley hills.

4) I am surprised to hear that the Berkeley marina operation is
suddenly having trouble, since our system has been running from well
before the Berkeley marina went on the air so you have been
receiving the same basic level of packet traffic from our network
since day 1, and your access point is located about 6 miles away
from our closet AP (although it is a perfect line of sight)

5) What I would suggest if you want to get the least amount of
packet traffic from my operation is to run on channel 6 in vertical
polarization or on channel 1 or 11 in horizontal polarization.
Channels 1 and 6 have Vertical sectors that can see the Marina, and
Channel 6 has a horizontal 24 db dish pointed torward Angel Island.
Cross polizarization should get me our of your hair. Also, since 6
is a 24db horizontal aimed above you, it should be pretty quiet.

7) Give me a call if you want to talk more about it.. (510) 207-0000
