We have recently deployed several wireless networks into existing Windows 2000 environments
We have found, despite trying several different brands of equipment, that we cannot get the connection to remain solid for any length of time. It will frequently experience dropouts of a second or two, which is enough to cause crashing of DOS-based applications run across the network

Furthermore, throughput on these networksis abysmal. Despite showing very strong connection signals (even with the devices 2M apart in line of sight), we measure only a fraction of the rated throughput. An 11Mbit (b) router and matching PCI card managed only 0.25Mbit/sec sustained throughput, while a 56Mbit (g) router and matching PCI card scored a measly 7Mbit sustained

Is Wireless networking just simply not what it is advertised to be
Are these constant brief drop-outs normal, or are we missing something basic
Should we be getting somewhere CLOSE to the rated throughput? Even half? Even quarter

TIA.

No, and no problem on DOS apps -- what "Network DOS"
apps are you still running? I still run many "dos" apps, but none
I would really call "net apps."

It's as realistic as Ethernet. Don't ever expect the nominal rate of the
"medium" to be achieved. Ours has worked fine for years, and we
are currently on our "3rd generation" have used a proprietary, then
802.11b, and now primarily 802.11g.

Maybe, what kind of distances and buildings are involved?

Even quarter?

Closer to the latter is probably about right. Maybe someone is doing better
and will tell you that.

But 35% of a wired Ethernet is about all you can expect in a
production network too.

There are many factors that affect wireless networking and if you experience
a lot of drops with all different brands of equipment then you may just have
a lot of interference in your environment. Cordless phones, wireless video
transmitters, etc can cause serious connection and throughput problems.
Trial and error testing with the removal of any device sharing the same
spectrum may tell you who where it's coming from.
