We used Soekris 4501 boards running Mikrotik software.  This gives you 3 
ports to work with.  We put a couple of the routers at our Cisco and 6 more 
at tower sites or customer locations.  Our main distribution site feeds 5 
other towers as well as local radios and each has a port and subnet of its 
own.  We have a 5 meg connection and can deliver up to 3 meg to a customer 
depending on loading at the time.  Some of our customers have vpns but we 
don't at this time.

I read with interest the comment that changing to a routed network was a big 
improvement. We are 100% switched at the moment with just one (Mirotik) 
router at the broadband feed. Our speed to the clients is OK (average 720 
kbits, sometimes more, sometimes less) but I feel it should be better. I 
have upgraded to 4.45 most places and instituted most of the other 
recommendations except going to a routed network.
What kind of inprovement did you see ? And did you have any VPNs that you 
had to NAT/PAT ? How did you implement it (ie. where are your routers) ?

 I have read the "Lockups" threads -- here is a problem situation that
 I would like some comments on.

 The problem system is an assortment of RG1100, RG1000, KN100 and KN105
 boards with Teletronic
 200 Mwatt, Teletronic 100Mwatt, SMC 200 Mwatt, and Orinoco Silver cards.to
 the internet.

 Connection to the AP-1000 is 2.4 Ghz link with excellent RF Level (Ch 1 
with
 30+ SNR  each way)
 and excellent ping time ( < 10 almost constant ).

 All users have good to excellent SNR and can be pinged. So the system 
looks
 stable and working. Users can ping the AP-1000 some times and some times
 not.

 Now the scary part. Each user can get a web page to begin loading, but
 always times out or
 at best loads slowly. Confirmed speed tests from an assortment of users
 shows
 24 K Bits/s downloads. System was running 10 to 12 times better for 
months.

 I say scary, because from an external perspective if the users have good
 radio signal, can be
 looked at with the Karlnet Configurator, and all ping then I assume the
 network
 is fine. This was not true.

 I swapped Radio Cards, AP-1000, and tried removing users from the system 
to
 see if
 a Client was causing the problem. Nothing improved even as I shut down all
 users and
 operated only one client with the AP-1000.

 Final fix was moving all client radios and the AP to another channel ( Ch
 9 ).

 I then used Net Stumbler to look for RF on the original channel ( ch 11 ) 
in
 the area
 and found nothing.

 On Ch 9 and Ch 11 the noise level at the AP-1000 is -73 DB. The typical
 noise level
 at each client is approximately -85 DB.

 Any comments or similar experience.

 Just a comment, we have a similar setup to yours with a similar mix of
 equipment. The noise levels we have are running in the -80's on sites with
 tower top amps and hi -80's to low -90's if no amp is used. We re mostly
 rural.  Our speeds are pretty consistant, but at times customers do 
complain
 of slowdowns to the tune of 200kbps. We attribute that to occasional
 interference to our 5.8gig links.  My concern is your relatively high 
noise
 level.  Changing channels probably just got you away from a very severe
 noise source.  I know this isn't much help, but I wanted you to know the
 system can work.
 We are routed also, that was a major improvement.  We have other parts of
 the system running Trango, Alvaion and Waverider equipment spread out over 
a
 rather large area and multiple towers fed by point to multipoint Trango
 equipment.  Once we reached a certain size we had to go from a totally
 bridged to a routed network. This alone really stabilized the whole 
network
 and made it very consistant.  Just food for thought...
