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. But
all running 4.46
firmware. AP is an AP-1000 repeater one hop from the main access point 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...
