It's done in the router's administration menu. The specifics vary greatly from model to model.

Code:
Wi-Fi networks have a range that's limited by the transmission
 power, antenna type, the location they're used in, and the 
environment.


A typical wireless router in an indoor point-to-multipoint 
arrangementusing 802.11n and a stock antenna might have a range of 
32 metres (105 ft).
signal strength vs quality

Only if your router has dual band capability. If you have a smartphone or other wireless device does it exhibit similar range problem? If you have checked all the suggestions and nothing has improved then as stated it probably is a laptop wifi card hardware problem.

Just a thought: that sounds like the performance one would expect from a WIFI NIC intended to have an external antenna, when the external antenna is OFF or broken! Is there, or was there, an antenna on this laptop?

to further that thought. maybe just maybe the connection is loose. Mine just got a little nipple on it that ya got a press real hard to get it to snap in to the connection.

yes I said nipple .. stop snickering...

Nothing so far has worked. I've connected to the wifi using a different laptop and no problems. The problem in my opinion is hardware
related. The router i'm using doesn't allow much configuration. So i'm at a loss.

Smile If you were real GOOD really thinking how would you?

Hello friends and curious. Isn't every hackers dream to use a phony mac address and phony IP address to attack a target. Probably using some foreign wifi network so they don't get identified. If you were the phone company. cisco routers and all how wpuld you defend?

Some bad firmware or drivers can cause weak signal strength. The router could also have a very weak signal. But mostly you need LESS stuff between you and the router. For laptops the antennae is often in the LCD part so orientation can help. Mostly I find elevation helps. Putting it on top of a book shelf above any would be mirrors and other obstructions. If your router is under the desk, perhaps move it up. Keeping the cat or dog from sleeping on it helps too. Mostly I wifi bridge through another device with better wifi. The wifi drivers can chew up a lot of resources on otherwise low spec'd machines. Where the equivalent ethernet drivers are lean and mean and easier to get going on things like BSD.

this will not fix the problem the 5GHz band will give faster speed at the cost of range
you need not move the router far if it's like behind the tv there is a lot of stuff in a tv that will eat wifi signal
if you use a reflector ( could help may not ) you need to be aware that a reflector has to be an even fraction or a multiple of the wave length away from the antenna if not it will weaken the signal with interference
you may need to boost the power on your wifi adapter read the iwconfig man page

this can let you max out the router's power but the router needs lots of air when running maxed out
and keep an eye on your speed if the router slows down turn down the power
it may not work for your router but it might worth a look see anyway
