Hi Brad,
My understanding is that the Ubicom based radios don't have this problem,
and are 100mW. The KN-50s did have this problem, but has now been
addressed by Karlnet. (I have several new KN-50 cards ready to go into
units this morning.) I like the KN-50s, been using them for about as long
as they've been out, and really like the MapleNet i19 and BWR modules they
come in. Very slick installs. To recap the Ubicoms have 100mW Prism 2.5
radios that do what Prism 2.5's do--namely have good power but don't report
signal/noise correctly. (Anyone know if there's a set dB you can subtract
to make it correct?) The KN-50's have been very robust in the field, have a
33mW radios, and report signal/noise correctly. Only downside is that I
require all my KN/Ubicom customers to purchase a router which I set the
password on and maintain. It would be nice if I could NAT to one IP on
these units...but, pretty darn good for $300/complete CPE.

Subject: [Karlnet] KN-50 Software Issues - Only with Hermes/Ruby based
radios?
All,
I'm currently planning, and about to seriously get into deploying a
significant number of new wireless clients, and I want to use the KN-50
units, but want to get some clarification on the issues reported with
them.
First, before I go any further, I do understand that Prism based radios
don't properly report signal strength on the client side, and the other
issues involved.
But are the issues with packet loss on the KN-50 based units specific to
those containing Hermes/Ruby based radios, or are they also present in
units with Prism radios? Does it matter what the base station is running
for a radio - Hermes/Ruby or Prism based? WEP?
Reason I ask is that I have several (a mix actually) Ubicom based Karlnet
clients running, and have had them running for some time now, and none of
them exhibit the packet loss bug that seems so prevalent and serious of
late. But, none of them are real KN-50's, and all have Prism radios in
them, and all are running 128 bit WEP, with Hermes radios in the base
station.
So, my question is does this bug appear with Prism radios in teh KN-50's
too? Does the current KN-50 software load support the use of Prism based
radios if I were to swap the Hermes/Ruby radios out for Prism based ones?
Does WEP seem to compound the bug any (more)?
Just having a bit of trouble finding out exactly under what conditions or
hardware configurations this issue appears, and trying to find a
workaround before deploying any more Karlnet hardware - or not deploying
it at all.
Brad
