Wireless ---- Geek Thread!!!

PILE ON!!!!

Otay...

I have relatives visiting and one has a dell laptop with the intel mobile link built in. When the unit powers up it finds the network fine and everything but after about 20 minutes it drops the network and goes all goofy. He said this has been happening at his home too.

The other 3 wireless setsup I have work fine. I set everything up on his machine to access my network and it worked for about 20 minutes.

So any clues as to why the system is just saying "bye bye" on him?

Could the heat from the unit be interfering with the RF Signal?
 
I think the dells cards suck.....I lose my signal and regain it all the time....for no apparent reason...I'm not moving around. I need to switch to a linksys g card and router.
 
The signal says its back but really isn't because he can't access the network

OS is XP.

The signal only comes back after the system cools and he reboots. That's why I thought about heat interference. That puppy does get super warm.

Hmmm..maybe that is the problem I'm seeing...mine seems to get pretty warm too....I'll have to pay closer attention.
 
If it's heat interference then the problem is easily solved through the PCMCIA wireless card since the receiver is outside the box.

Weirdness abounds.
 
is the wireless card built in? do you have a different wirless card or usb wireless thingy to plug into it?

I'm pretty sure that head does not effect the RF signal. could be a hardware defect.

The wireless card is built in.

No.

How do you give head to an rf signal?

Heat effects rf all the time. Gross displays of this impact are solar flares and summer days over 100 where you get static and bleed on radio stations.

no that's the electromagnetism of the solar flares, not the heat.
 
Well now I'm back to "It's just a shitty dell." :P
 
If it works when it is cool, and then after being on for a fixed amount of time - then it is heat.

It doesn't have to be the RF signal that is deteriorating - it sees the network, so it is getting RF signal.
The issue can be the heat and it could do any number of other things - heat increases the resistance for circuits, so they are not going to be happy.
It could be something as the metal connnections of the card swell and it loses solid contact.

If you ever have a computer problem that works perfectly on starting up, and then gets increasingly worse as time goes on - that is usually a memory leak.
If you have an issue where it works perfectly on startup, and then after N minutes in it shows the problem, that is nearly always a heat issue and it takes N minutes for it to build up the requisite levels of heat.

I have no remedy for you except try to find out where and why it is heating and if you can resolve that.
 
Thanks NDN...

He can just turn it back in if he wants. He is a university prof and its the schools machine. I'm going to tell him to get a new one.
 
Unfortunately the link is built in by the idiots at Dell.

You could insulate a PCMCIA card with foil or somesuch.

1) While they very well may be idiots over at Dell, I don't know. But I do know that the laptop is a Centrino model, which means that it has to have a built in wireless chipset and a P4M chip in order to get that designation. As a result, Dell didn't make this decision, Intel did.

2) Insulating it is the last thing you want to do - you want to move heat off of it as quickly as possible.

3) It is really not a big deal if it is built in and not working. It should still have a PCMCIA slot and you can just put another card in there and disable the built in one in the hardware profile.
That doesn't resolve the issue of where the heat is coming from and if that creates larger issues.
 
Extremely few female computer geeks so I have a good excuse for not having the foggiest f**king idea what you fellas are talking about.


Sounds good though. :)

I was working under the assumption that the PCMCIA card would not be the source of the heat.

This method works for heat soak in automobile starters.

well I have a wireless network at my place and had a similar problem

i fixed it though

Uhmmmmmm how?
 
I may have to set up a wireless network, I got way to many freakin wires. If I do it will be the G standard.

2 desktops,1 laptop, and 1 xbox.

is it really as fast as a hardline??

If you have a fast connection to the outside, then you connect to it through a router at 10Mbps, and you connect to machines on the inside of your network at 100Mbps.

The G wireless protocol is at 54Mbps - so it isn't as fast as the interior network could be, and you will connect to the outside network no faster than the limiting connection speed of your router going out.

That said, the B protocol is 11Mbps - so even that is faster than what you can connect out at anyway.

So the faster wireless really only matters in terms of your interior network - so for games and file/print sharing.

sweet, I'm going to get the fastest though. It's a penis thing.

Also, I remember reading about "they" were working on making the internet a lot faster.
 
The G protocol hardware will also work with the B stuff - so if you have a G router and a client with a B card in it, it will still work on the net (just at a lower speed).
I haven't tried to see if a G card will work on a B network at a lower speed - I could see that not working.

Mine is built in, and I love it - it just works. I don't encrypt mine so as to have less delay in the system - but I have no real neighbors where I live, so it isn't an issue.
I'm curious when I'm in the States what networks I will be able to autodetect with it.

I'm mainly hoping that my mom's apartment complex has someone nearby with an open connection so that I can use that and not have to do dial up to get on the net while I am there.

I need to get on the net to run a few things on my servers, otherwise I would just not bother with it during the few days I'm there.
I'm tempted to look to see if any nearby hotels there have fast net connections in the rooms and just get a room there while I'm in town - but I also would rather save the money and just stay with my mom.

We shall see - maybe she will have DSL by then, her workplace is supposed to be getting it for her - I can bring a router if that is the case - hell, I could bring the wireless one :)

The main headache is anything I leave this country with, I need proof that I have already paid duty on it so that they don't charge me for it again when I come back into the country. I don't know if I have the receipt for the router anymore.
 
I could be a driver issue.

My laptop dual boots linux and Win2k. With Win2k, the card will choke while transfering large files - even with WEP turned off. With WEP turned on, it rolls over and dies quicker.

With Linux, it doesn't choke. Go figure. To me that would be a driver / OS issue. And, this happens with two brands of cards: Orinoco and D-Link.

Told ya wireless can be flaky....
Click to expand...

My stuff is working fine. This is the first unit I've seen doing the flaky thing.
 
I have seen personally, and heard of many others that have the Linksys wireless routers and they have tons of problems.
I purposely avoided those this time and went with D-Link which I had never heard of prior to moving here - seems pretty good for me - then again, I am sitting about 5 feet from the thing.
 
LOL! I bought linksys for the same basic reasoning as you bought d-link.

My link sys setups on the two desktops, the wap and the laptop are all humming right along.
