Is it advisable to employ a wireless mouse and keyboard if using a system
with Wireless Internet?

I have used the 27MHz and 2.4GHz versions without any major problems but
tend to acquire the combo versions rather than buy a wireless mouse and
then add a wireless keyboard giving you 2 receivers. I have so far
encountered only one faulty 2.4 GHz USB receiver but that was replaced
under warranty. One of my neighbours has had a problem with the USB
ports on an oldish computer whereby there seemed to be insufficient
power to operate the 2.4GHz receiver but removal of his other USB
devices cured that, device manager did report the ports as USB2. I have
so far had no RF interference issues.
Looking at your other post, did you try switching off the wireless
router to see if it was an issue?

Generally speaking, I'm asking if there are potential problems using
wireless keyboards
and mices in conjuntion with a routed systems. Judging by your reply it
appears that
according to your experiance there is a possibility of problems.

No I didn't. It didn't occur to me 'till I took the pc back home to
reinstall.
When I got it home it worked fine. Might have been better if it had a bad
system
install. I still can't see how the WiFi could have caused this.
Come to think of it, I've had the same problem once before in my workshop.
I installed a dlink DIR300 G router in a pc and seemed to install ok.
However,
when I installed a receiver on my other pc, a Dlink DWA-510 Wireless G
Desktop Adaptor the pc
with the adapter behaved the exact same way as my original post.
Removing the adaptor rectified the problem. I'm unfamiliar with Wireless
systems and for me I think
they are not worth the trouble. Especially since a friend recently told me
that his "protected" wifi had been hacked
by someone and he now has a battle with the telephone company over a $5000
internet bill incurred over two and a
half month period.

Thanks for the kind reply, LR

The problems I have encountered have been with the mouse, keyboard and
computer components and not with interference from the WiFi network.

It was the correct PCI Interface slot? PCI 2.3

My only experience is that it causes no interference. We hava a Logitech
V470 sitting about 2 feet away from our DGL-4300, with no problems.

Bluetooth "hops" from channel to channel (he said in his
techno-illiterate way) while WiFi stays fixed. There _could_ be
interference. HP have a PDF you can download discussing it.

A lot of the wireless keyboards and mice only use 78 channels, don't use
2780 MHz, rather than the 79 for Bluetooth. I have wondered whether they
partly do this to avoid having to conform to Bluetooth standards.

That should have read 2480MHz not 2780.

I've never had any problems at all. Wireless k/b-mouse systems work on
totally different frequencies.

Look at section 3.2

Logitech V200 and G7 mice work on 2.4GHz. Lots of others are now on
2.4GHz. Search Google for "2.4GHz mouse". There are also Bluetooth
mice on 2.4GHz. Search Google for "Bluetooth Mouse".

Most 2.4GHz mice work like cordless phones. The FCC graciously allows
adaptive frequency selection to avoid interference. The mouse picks
one of 80 assorted 1MHz wide channels, sends data in short bursts, and
does not change channel. Interference is minimal. Unlike 802.11
FHSS, mice are not required to frequency hop over the entire band
(thus obliterating everything).

Keyboards and mice are not going to an interference problem because
they're not on the air long enough to cause a problem. That's not the
case if you use BlueGoof for file transfers and other apps that
generate lots of traffic.

I once tried to intentionally create interference with a 2.4GHz mouse.
I had the mouse doing continuous movements. No noticable drop in
thruput. However, I can literally kill a wi-fi file transfer with a
BlueGoof 1.1 adapter (which does not have Adaptive Frequency Hopping)
by simultaneously moving data. That's NOT the case with 2.0, which
will find an empty block of channels.
