My Linksys wireless router causes nothing at all on any of my vhf

Likewise I'm using a D-Link with no problems. The 144/440 rig sets
about 3 feet from the router and the CAT5e gigabit network cable runs
along with the coax for a ways and then parallels it for another 40 to
50 feet.

I can set a 2-meter HT here on the desk and it'll work just find. If
I move it up against the computer cabinet it'll just open the squelch.





After several months of just not listening to my 2 meter base station, I
finally took time to find the source of the interference that held the
squelch open on the repeater channel I listen to most often. Turned out it
was my Dlink DI-604 router. I borrowed a Linksys NR-041 router from my
neighbor and it works a little better. I can now listen to the 145.390
repeater, not because the Linksys puts out no RFI, but only because it puts
it out in a different place (mostly in the 146.46-146.58 range). I will
probably invest in a newer router, probably wireless. Question I have is
does anyone have any experience with the new breed of wireless routers that
are reasonable clean in the RFI/2 meter spectrum? Thanks.

I would suggest FIRST, making sure you have the latest firmware for the
D-Link router.
Know how to update the firmware properly -- it is covered on the D-Link web
site.

Sister had a wireless D-Link router and the update/upgrade of firmware
seemed to quiet down the RFI. Likely a poorly written piece of code by a
programmer -- who has never heard of RF.

No, a 604 is a wired router, I would suspect it is a poorly wired or bad cable
that is a multiple wavelength of that particular frequency... I use the 604
( non print server ) and 614 ( print server ) routers with no problems at all.

There may be multiple revisions of the 604, with significantly
different internals. I've had similar RFI problems with some routers
and WAPs, and have concluded that some of them use buck-mode voltage
regulators (DC-to-DC converters) which put out strong harmonics of
their switching frequencies. Similar devices from the same
manufacturer, a year or two newer or older, don't have these emission
problems... I believe that the voltage converters in the trouble-free
units probably incorporate a "spread spectrum" modulator on their
switching oscillator, and thus emit a broad-but-low level of RF hash
rather than discrete birdies.

Remember that D-Link (and Linksys) will change the hardware chipsets within
a model number. For example, one product has 5 different chipsets /
versions depending upon version number and serial numbers on bar code of
product -- SO a clean model may be a different version from a dirty RF one!
