Hills antenna feed problem

Can anyone get me a quick reply on this problem?

I have a DLink 2000AP which keeps resetting itself every 20 odd seconds.
I have traced the problem to the final 2foot cable length of a 19db hills antenna - ie: only resets when the antenna is connected to the AP.

I put a multimeter across the terminals of the N connector on the antenna feed and got a resistance of 0.3ohms (almost short circuited) - is this normal? If I remember correctly, its a dipole inside and as such should have a very high resistance (if not open circuited alltogether)

Any ideas?

Don't worry.
It was because the Acess points don't like transmitting on channels 12 or 13.
Yeah, I know, it makes heaps of sense.

Bring on the 900ap+ I say!

John,

The dipole in the Hills Grid will lookk like a short when you connect a meter. this is the DC resistance and not the resistance at 2.4ghz.

How about this for its interest factor....

These two antennas, about 1km apart pick each other up with a -24db receive signal and negligible noise. However the 2000ap+s wont even reliably talk to each other when forced down to 1MegaBit.
They are an absolute piece of 5h1te - Stick with the 900ap+'s or go to the linksys if you need 802.11G.

John,

Now that really SUX.
Just goes to show. the number means nothing.

Hey we have some new AP's coming in within the next couple of days.
200mw AP's, 100mw AP's with Linux Kernel and a few more 200mw cards.

Told you so :P

Im gonna call dlink tomorrow about my 2.... they give me a good 15 megabit filetransfer speed between them, and if your lucky you will get a whole iso copied without needing to powercycle them..

John, I was looking at getting a pair of DWL-2000AP or DWL-2000AP+.

Have you tried the 2000AP+ (which I asume you have) in a test setup in close range like room to room?

One other thing about a high gain antenna with short distance is you can have too much power resulting in the same effect as having poor power for transmitting/receiving. Does the 2000AP+ have a setting full power output to adjust?

I'm still having a hard think on the DWL-2000AP as lots of people have had good and bad runs with them. The versions and the amount of firmware updates for each revision seems to be growing, but does not seem to address one common problem of the access point dropping its link every now and then.

Wizz,
regardless of antenna strength or whatever, I replaced both ends with 900ap+'s with standard firmware (not the power hack) and have a rock solid link.
I wouldn't recommend the 2000AP or the 2000AP+ to my worst enemy.
Every brand name has a lemon, and the 2000AP(+) just happens to be D-Links, every other product from then I have used works fine.
Add to this the fact that 2 separate people advised me against the 2000's however I was adamant that they must've been doing something wrong.
Feel free to correct me, but I would advise you to talk to richms first - he takes great pleasure in the 'I told you so' speeches!

Actually I think I have found the problems, its to do with it not properly associating and disassociating mac addresses in client mode. Bridge mode was just as unsucessfull when I was moving the laptop from one ap to the other, thats when it was stopping working

I have the 2 revision B accesspoints running in AP and client mode running my MP3 player on the client end and it seems to have held up for several days without it needing a powercycle, and if there was a brief dropout then the player would have stopped. Its on the stock antennas for about 6 metres thru 3 walls, so signal is about the same as it would have been to the shed where I was having all the problems.

I would still go for the linksys, there is a more active hacking effort going on since they chose to base them on linux, and that means things like more power, and routing daemons running on the box itself. all very cool.

Thanks guys, I'll sit down and have a thinl about this.
