Unused antenna cables in M1330

Being a newbie ...why are there so many unused antenna cables in the wireless chamber of my Dell XPS M1330.
My quest is to get wireless coverage in the rear bedroom of my flat. I can get coverage of my work wireless connection inside the freezing front door and then disappears as I go upstairs.

How can I bridge that 30feet?

 

Some of the wires are for the(optional) mobile broadband card.

 

If you have a CCFL backlit screen, you have 5 antennae wires - 2 for a Wireless-G card (Black and White), third one that would be used for higher end wireless N cards (Intel 5300 and 6300) (Gray), a bluetooth antenna (Blue) and one more for the WLAN card if you have one (I dont recall the color).

With LED backlit screen you don't get a third wire for wireless N cards.

 

Wireless signals dont travel well upstairs. Your gonna need to reposition your current router or buy another router/repeater.

 

It doesn't travel upstair because the signal propagate parallel to the antenna
(((((((((((((((( || )))))))))))))))))))
So the solution is to shift the antenna to this = position.

 

Router antennas are omnidirectional.

brushless: What router do you have?

 

All routers antenna are X/Y Axis (|_) directional unless stated otherwise.
Check Books on Wireless Networking Technology.

 

Rubberduck/dipoles are omnidirectional on a horizontal plane with vertical beamwidth of 75deg~, so it travels upward as well given the space.



Pointing the antenna like you said wouldnt help him because his room is in the rear of his flat. The horizontal signals now would be focused vertically to the ceiling, putting him on a weaker spot.

 

If most power is radiated in the horizontal direction, how about try rotating the router/antenna by 90 degrees ? I'm not sure where is he trying to get the signal: up or in the back room on the same floor? If it's on the same floor, try moving the router to another place if your cable allows it.

 

Isn't his room on the second floor like most flats vertically above the first floor?
Anyway placing the router in higher position will help as well.

 

My circumstances are thus:- I live very close to my workplace. I can get my employers wireless connection at home albeit inside the front door of my flat wearing hat and scarf LOL LOL. I have a legit connection for work. It's when I go upstairs to the rear of the house I loose connection. How do I span that crucial 25 feet? I have heard of a repeater and the "Turbo Tenna" etc.
