Please Help me with 2 problems on my 1520

First off, yes I love it and its wonderful- except two problems.
1st- the less vital but easy to explain one. My speakers sound fine, but when I plug in a set of headphones (I tried 3 different ones) I get some faint yet annoying electronic sounds or feedback. When I play music it seems to be drowned out, otherwise I can hear the kind of high pitched distortion and its annoying. Also, when I use the vertical scroll bar, I get a kind of record scratching sound (but not that high pitched). Do you guys think I have a busted sound card? Any ideas how to get around sending this back to Dell? Is this typical on newer laptops?

2nd- Wirelessly connecting to a netgear router. I have no trouble with a wired connection and my brother's XP laptop connects fine, too. I can also see the router and its full signal strength, but it won't allow me to connect. DellConnect fixed it last night, and I was wireless, once they disabled wireless card control. However, the next morning it stopped working. I figure its a problem due to two wireless computers trying to connect to the same WEP Key number (I'm using WEP, turning it off doesn't change anything for either computer). However, I've also tried adding new key and changing it from automatic to shared numbers and that doesn't seem to help. Anyone have a solution? I'm really stumped.

 

Update your sound card drivres.

I think for the wireless, try disabling the bluetooth option.

 

Intel or Dell wireless card?

There is no problem using the same WEP key for 2+ computers. Try enter WEP key again, make sure you use the one same as the router. In fact, you should try to use WPA instead of the old WEP.

I don't think this is the issue, I have 4 wireless laptops that connect with the same secure key.

 

Hey, you could always just reconfigure your wireless. I had to do that one time, took 20 minutes and made it a lot less confusing. I'm using WPA-PSK (TKIP) with my Netgear Router. This security only uses just 1 password that all the laptops can use. You don't have to deal with all those Keys and stuff, gets a little bit confusing I think.

 

It's not the Bluetooth. That wasn't a problem last night, but I disabled it as you guys suggested and still no luck. Maybe I'll try one of the other formats in a bit, my only concern is that my brother has a laptop called a Tangent and he doesn't know what his card can connect to, but I'll give it a shot.
I'll try the sound card drivers too.
Thanks, and more advice appreciated.

 

It's the Intel wireless card, 4569 or something with a/g/n.
Also tried reinstalling sound drivers from dell-- no dice.
Anyone else ever hear electronic sounding noises, possibly from the hard drive spinning (?), through their laptop's headphones? Scratch that, it seems to be coming from the laptop with the sound off and my head next to the computer. I guess its just some part of the laptop.

 

It's EM interference caused by the a) moving metal parts of the hard drive and b) the low frequency signal sent by the scroll bars.

The sound card electronics aren't properly shielded, I guess.

 

you need to update your drivers

 

What you said about the electronics interference makes sense. Disappointing though since it sounds little can be done about it.
As for the internet, now it seems to be working. The only thing I can come up with was turning off the Bluetooth was in fact the conflict. It the change wasn't immediate so I didn't think that was it.

 

I am having the noise problem with my 1520 as well. Cant use the earphones at all without hurting my ears. I guess i will buy a express-slot sound card to solved it.

Update: the noise is getting worse. I can hear without using the earphone.
