Wi FI Problems

[Falci]

Hi,

This week, after about a day without internet connection (blame the provider on that) my Wi Fi connection to our LAN suddenly was lost.

Even though everybody else in the buiding I live is able to connect to the router through Wi Fi and to acess internet, somehow my PC can't quite detect our LAN anymore. There has been no changes to my hardware and my friend who owns the router says he didn't mess with the LAN/Internet settings at all.

Windows Vista doesn't point any problems at all with my DLink Wireless modem so what the hell can be happening and what can I do?

First how fare are you from the router? are there things in the way that would cause this problem? something new that wasn't there in the past?
Other than that, and the hardware isn't malfuntioning..
If it's a quick secure wireless and thats enabled, disable it and try removing the drivers, reinstall drivers and reconfiguring the thing.
If all else fails, do the above but also reset the router.

The router position hasn't changed, my neighbour showed me. My PC didn't either. The guy who lives above me apparently is able to connect and he is the one who's farther away from the router.

My friend brought his laptop to my room and could perfetly connect from basically the same place my PC is. In fact, I had a great connection before this problem arose.

I've already uninstalled and reinstalled my Adapter, using it's driver CD too. The router has been turned off and on already. I've delete and tried to recreate the connection a number of times too. It's a simple LAN with a password. The password hasn't changed, my friend guaranteed me that the MAC permission list didn't change either.

It's like nothing has changed and yet it simply can't find the network anymore.

If something did change, maybe we didn't notice at all.

Can you connect to some different wi-fi routers? Library, coffee shop, unsecured stuff nearby, etc? If you can find or connect to other wi-fi things I don't think it's your computer. If you can't then I think it is your computer. You tried the obvious things already. I know it might be impractical to test that if there aren't other wi-fi connections readily available where the PC already is, so that might be a no-go anyway.

If you still find yourself in a bind, sometimes it really is your computer being weird, either because the hardware died or the software died. If it's the software sometimes a system restore will bring it back. It shouldn't hurt anything though.

Problem partialy solved.

Apparently, the guys from the apartment above bought a 7 dBi gain antena to put on the router so that they could access the net better from their house. Unfortunately the antena doesn't actually work and apparently when the original was returned to it's place it stopped working properly. The signal was reaching a lesser distance.

So We've put my 5 dBi gain antena there on the router and they lent me a small antena with a cable so that I could have access until I buy a definitive 5 dBi antena to put on the router (we're going to split the costs).

Ahh, antenna problem. Solved that one in my house with a wireless range extender (grabs the signal and amplifies it). My friend solved it with a massive antenna he says looks like a TIE fighter. :)

Yeah, I had that problem, until I got access points with MIMO (http://en.wikipedia.org/wiki/MIMO)on them, now I can access my N network anywhere in the house, and even 30 feet away in the hammock out back.

In short, it's wireless, if it's a signal problem, best bet it's the antenna. ~ or not close enough.
If the signals low, good luck keeping it on the net.
If the singals good, then in most cases it's gonna work.

Anything else from that point, treat it like a hardwired network, reboot the modem and router. hit the rest switch on the router. check your connection and drivers.
Done.

Other than that you might be looking at some network virus etc.
