Wireless Network - Unwanted Sound/Noise/Static

[rmol123]

Greetings all, I have a state of the art HP Pavillion XH176 running Windows ME. I just installed the Linksys BEFW11S4 Wireless Access Point Router. I am using this with the Linksys WPC11 Instant Wireless Network Adapter.

Problem:

Every time my computer sends or receives data from the internet (DSL), I hear static (noise). In other words, I hear static while my laptop loads any page/internet site. Once the page is loaded there is no noise. I also noticed that if I plugged the router directly to my laptop with the appropriate cable, there was no static. I’ve also tried using D-Link products and I discovered they produce even more noise than the Linsys ones.

I am using the most recent bios available and my laptop seemingly has no other issues, other than it’s a couple of years old.

I would appreciate any feedback. Thanks and good-day.

sounds to me to be a speaker issue. is that where the sound is originating? "Jack of all trades. Master of none."

It probably has something to do with the frequency range of your wireless products and the frequency range your DSL is running at. In my case, when my 2.4GHz phone was being used, my wireless lan would slow to a crawl.

If you have the option, just try changing the frequencies of your wireless lan. This may or may not solve the problem. It solved mine.

Hello,

Thanks for the previous feedback. As it turns out the sound is generated by the sound card. If the sound card is completely disabled, then I do not hear the static noise. But unfortunately I hear the sound when the card is enabled. I've tried changing the channels on the card/router w/o success. I've also tried changing the wireless card's IRQ settings but I still get the static noise. Once again, I would appreciate any feedback.

it really don't seem to be repairable being that it is a laptop. you would have less options than a pc. try to see if any updated drivers are available to you for your card and/or try to find another connection type for it. but it looks like its the card its self. can you mute the onboard speakers and try some that you can connect to it?

sorry, hit enter too fast.

it might be the speakers and not the card and may or may not be fixable depending on your laptop. "Jack of all trades. Master of none."

soz everyone - this is a bit off topic....this is what you get when you turn a sound engineer into an IT developer
this sounds like an audio issue

this could be one of 2 things -
1. your wireless card broadcasting on frequencies it's not meant to
2. your sound card isn't sufficiently protected from stray EM (LACK OF IMMUNITY)

It's probably no.2 - in other words, you've got a %*^* soundcard on board.

Basically, your wireless card broadcasts on the EM spectrum; this EM radiation can be picked up (induced) by the coils and circuits of the sound card, and (unless the card is suitably filtered) can be amplified through the audio channels into static on the speakers.

"If the sound card is completely disabled, then I do not hear the static noise."
This would be because the card's amplifiers are switched off - the EM would be extremely (whisper) quiet if it were induced on the speaker cable, therefore it must be induced at some point in the pre-amp circuit.

From the UK Radiocommunications Agency website
"the European Community (EC) Directive on Electromagnetic Compatibility has been implemented in the UK by the Electromagnetic Compatibility Regulations 1992. The Regulations apply to all electronic and electrical apparatus, both commercial and domestic, including radio and television receivers, and cover emissions and immunity."

It basically specifies 2 major points...
1. EMISSIONS - the device doesn't cause extraneous EM emissions (outside of any frequency / power it's licenced for)
2. IMMUNITY - the device is capable of receiving a certain level of interference without malfunctioning.

It may be worth contacting both manufacturers to advise them of the issue and seeing if any owns up to the problem! <marc>[ul]help us help![li]please provide feedback on what works / doesn't[/li][li]not sure where to start? click here: faq581-3339[/li][/sup][/ul][/sup]
