Laptop can detect wifi networks, but won't even try to connect


Recommended Posts

I've noticed that sometimes I can see wifi networks but I can't connect to them. If I try to connect, the computer appears to try but instantly gives up. No error message or anything pops up. It just gives up and I'm back to the list of available networks. I've had this problem with unsecured networks as well as secured networks (WEP and WPA). Some networks are 802.11 g some or 201.11n. The strange thing is that it's always the same networks that I have this problem with and they are usually networks that I can connect to with other laptops, ipads, smartphones - even an old PDA. The only device that had a problem was my netbook. I don't think that it's the routers because other devices can connect to them without any problems. And i don't think that it's my laptop wifi because it connects fine to other networks. It seems that certain wifi networks can't be connected to, but other's work fine. It's not an intermittent problem. Those networks that I can't connect to are always unconnectable. Those that I can connect to, are always connectable.

I'm using an HP Mini netbook with Win7 (home edition).

I've asked a few IT techs (some of the routers were at work). They tried a few things, asked a few questions, but were unable to come up with any idea of what was going wrong.

Any suggestions? Thanks for any help.

Click the start button and type in "manage wireless networks". See if you have any conflicting network setups. Usually if they have the same SSID, it can throw computers in for a loop.

An example would be that both my current SSID and the SSID at my parents place was both by default "Netgear", the computer didn't recognize them as two separate networks.

I have seen a few instances where the IPv6 stack of Win7 actually causes problems with some wireless adapters even though they aren't connecting to an IPv6 network. Removing/disabling any and all parts of IPv6 magically has solved the wireless connectivity problems for me in the past. Can't hurt to try. http://support.microsoft.com/kb/929852

And have you looked at the logs?

Have you tried the diagnostics?

Without some actual info to go on your never going to fix it.

Lets just all make random guesses to why something does not work -- I mean why should we even bother to look at the information the OS will give us to why something doesn't work when we can just randomly guess to what the problem is ;)

I guess its because Mars is retrograde currently..
