We ran networked computers with the main Writelog server being hardwired 
to the router and the rest wireless.  No issues to report other than one 
of the stations had the infamous "no data entry window" bug (reported 
earlier) which required a full de-install, registry and .ini file cleanup, 
and a reinstall to fix.  A time consuming pain in the ass but at least 
solvable. 

I networked Writelog this way for dupe reasons and to maintain a central 
backup of the logs on my laptop should one or more of the computers fail. 
It also makes it easy to plunk in a new PC and re-replicate the data over 
the network should one fail, or have one replicating all the time ready to 
plunk in should the need arise. I took out all the bells and whistles and 
just had duping and the mult list visible as the old timers easily get 
their knickers in a twist and refuse to use anything that smacks of change 
or complexity. 

I would recommend to anyone doing this that they put the master Writelog 
server on a laptop with any of the power save features disabled, or on a 
PC with a large generator capable UPS for at least thirty minutes uptime. 
Ditto for the wireless router so neither go down when the generators run 
out of gas.  This would solve a number of potential problems.   Also, in 
wireless workstations.  Some of them tend to roam to their favourite 
default hot spot name, ie. Linksys, default, etc.  Change the advanced 
settings so that only your 802.11 network name is visible and at the top 
of the priority list. 

And setup an account on each PC that comes up as default on boot but is 
devoid of any Power User or Administrative functions - and password 
protect the administrator account.  Blocking the flying fingers of field 
day fate is always a wise move. 

I suspect that issues discussed of late were related to RFI.   Writelog 
does some funny things when random and sometimes lengthy network 
disconnects happen.  I've noticed no RFI issues with 802.11 routers as 
long as the router itself is not in a strong RF field area and there are 
no long network cables plugged into it (6' and shorter seem to be fine). 
Shielding the router and providing RF blocking from the power supply leads 
will help as well.  Ping your workstations continually during field day 
(or a contest) to see if you have issues.  If you do, fix them right away.
