We recently moved our desktop computer (HP Pavillion, Windows 7) into another room and are trying to wirelessly connect it for the first time. The desktop has an internal 802.11n wireless card installed. Our router is the Linksys WRT54g router (which is super old), and all other devices and computers have no issues connecting to it. This desktop does not even recognize that there is a wireless signal, though. It says that "no connections are available." Troubleshooting does nothing.

I'm honestly at a loss for what the issue could be at this point. It just doesn't make any sense to me. I've fiddled around with things on the router setup page and looked around in the properties of the wireless adapter, but nothing seems to have any effect.

The computer is not out of range of the signal.

what computer do you actually have (model), are there antennae on the back of the computer?

the lack of range makes me think its because of the antennae, them either being missing or not connected properly.
should be some of these on the back of the computer http://www.wvshare.com/img/preview/SMA-2.4G-2DB-Antenna_l.jpg
or you will either find some of these if the antennae are missing http://i01.i.aliimg.com/wsphoto/v0/1032538963/Rp-sma-needle-.jpg

do you not have something like this in the pc?

Card has been updated. The computer recognized the wireless network temporarily, but now it's gone again. I would wonder if this were an issue with the router being out of range, were it not for the fact that I'm using a laptop, phone, and printer all connected to the same router in the same location.

Router is currently on channel 6, but changing the channels hasn't affected anything.

It's not picking up any networks. I'm sitting here at the desk of my desktop on my crappy old laptop, which is picking up a "good" signal from my router, and a weak signal from a neighbor's somewhere. But this desktop isn't seeing any networks at all.

Thank you so much for trying so hard to help me. I really appreciate it. :(

ok, make sure the antennae on the wireless card are facing upwards and no power cables are running across or near them.

make sure they are also properly tightened into place.

it might also be worth if this does not work, trying a different slot in the pc.

Everything's good with the router.

I can't see trying a different slot in the PC. I'm not very knowledgeable on PC hardware, but it's an internal card, and I actually can't locate it. I was going to install a wireless G adapter that we had into the back of this computer, and there isn't even a place for it.

...what's weird is that when I connected the modem and router in this room to update the driver, after it was updated, it recognized the router and connected through it. After moving the router back into the room it's supposed to be in, it stopped recognizing it. So... do you think it could be a range problem? I wouldn't think so, since like I said I've got all these other devices connecting just fine in the exact same location. I was under the impression that the router itself was what limited the range, but is it possible that the wireless adapter is just a piece of crap and has a really poor range for picking up signals?

Oh my god.
It's missing the antenna. It didn't come with one.
The adapter isn't in the normal spot where the typical slots are (for when you have to add an adapter)--it's way down at the very bottom of the tower. I checked back there, and sure enough, there's a little gold nub sticking out that I completely missed. Took the antenna off the other adapter we have, stuck it on there, and BOOM, there's the internet. Working great now. :)

Thank you so, so much for your help! I really appreciate it. I probably never would have even thought to check for a damn antenna that probably should have been included with the computer. lol
