usb adapter sees network but does not connect
Good day all,
I have bumped into a bit of a problem that I have issues resolving. I am trying to connect to a network using usb wifi adapter. I get 5 bars of signal which is max on the scale but it will not connect.
Network is WPA2 personal / AES, settings are correct as well as password. The connection worked for a bit and then I was dropped off. I have tried reseting IP, i have tried changing USB port connection on the laptop I have restarted the laptop...
The thing that baffles me is that when I take my laptop out and go to where I can get signal with the built-in wifi adapter I get connected without a problem...
Any suggestions will be most appreciated... Thanks in advance

Are you able to connect at those same locations using the USB adapter? This should let us know if the problem is more likely on your end or with the one access point you can no longer access.

What kind of network hardware is being used for the access point that is giving you the problem?

Hi Chuck,
Thank you for the welcome I did not take the USB adapter out to see if it connects where I can connect just by using the laptop since I get 5 bars on the signal scale. I only have to move around the building that is in front of my room and I can connect with the laptop. What i cannot understand is why it connects with built in wifi card but not the USB one. I do not know what type of access point is being used as it belongs to the company I work for and I do not have access to it. If deemed necessary I can find that out... I do not think access point is a problem as I can connect with my laptop or even the phone.

Is there a possibility that someone in your company's IT department noticed that the access point was being used by a new and unknown (never seen before MAC address of the USB adapter) device and blocked it? That might explain why you might have been able to initially access it.

Testing the USB adapter at other locations that work with the laptop's built-in WiFi should give a pretty good idea if there is some kind of software issue that prevents the USB adapter from properly connecting.

Is your company using a VPN for access?

What operating system are you running on the laptop and what is the brand and model number of the USB adapter. No guarantee that I'll have a solution, but the information could help somebody else here to help you.

I contacted IT manager regarding this to see if he could help... No one is is blocking access as the network is setup for our usage after work. There are 3 of us from my department that have the same issue. I went to check model of the adapter but got nothing of it as it is some cheap antenna. It is also connected to internet at the moment... :/ Have not got a clue as what could it be??? My mate has got Alpha AWUS036NHR adapter and as I said has same issues. One laptop is running Vista two of us are on Win 7.
And yes, VPN is used

I think I am quickly getting in over my head on this one and hope we can get someone with more networking knowledge in here. Not sure if and how a VPN connection might come into play. Other people having the same problem with different adapters and operating systems would want to make me suspect the problem lies in the access point. One other useful piece of information that may be of help would be to give us the full listing of an IPCONFIG /ALL command results while you have a working connection.

Hello,

Am I missing something as to why you don't just connect using the built-in wireless adapter if the USB one is giving you issues?

----------------------------------------------

Assuming there is a reason for it, have you tried disabling (not uninstalling) the built-in network adapter before trying to use the USB adapter?

And as cwwozniak requested, let's see the ipconfig /all please.

To do so, do the following:

Press and hold the Windows button + R.

In the Run box type CMD and hit Enter.

In the Command Prompt, type IPCONFIG /ALL and hit Enter.

Right-click the Command Prompt and click "Select All".

Right-click the Command Prompt again and click "Copy".

Then paste these results in your next post.

----------------------------------------------

Lastly, have you tried downloading and installing the latest drivers for the USB network adapter?

Hi Cody,

I do not get signal in my room and since I am in the middle of Sahara desert and being summer time you can imagine that sitting outside could literally cause a meltdown and that is why I am trying to get the external one working.
I will submit IP configuration once I get the connection on again...
I had one more thought... Could it be that router or access point would block MAC number if there was if the signal would be on/off (because of the noise - not sure if that is the right expression...) and then after a while reset and allow access again?

I'm not quite sure what you mean by that.

--------------------------------------------------------

As far as the IPCONFIG /ALL goes, I would actually prefer reports both when you are able to get a connection, and when you are not.

Hello,


I thought it will be kinda hard to understand what I mean :/ I will try to rephrase if I get an idea on how to...
Below is IP configuration when the antenna is connected. At the moment I can't send the one for disconnected at this time. Will do ASAP... Maybe this will give you some ideas on what else could be tried...

g3nt3, you have missed a couple of my questions. Please answer them.

Once you have disabled the built-in network adapter, perform the IPCONFIG /ALL again and post the results here.

Understood. Obviously it's an intermittent issue, so just whenever it happens again.

My bad... Sorry...
I did not install latest drivers on my system but I will, already downloaded them. I did install them on laptop of my mate and it made no difference.
I had tried switching of the built in adapter but to no avail. Tried switching off the system while adapter off and turning on again and it made no difference either. IP configuration below...

OK, all looks good in that IPCONFIG /ALL (as expected since you're connected to the internet).

----------------------------------------------------

A note about the drivers, I don't think this will solve the problem, but it's one of those "just in case" things that I always try to do. I've been surprised a few times.

Just post it whenever you can.

I'm getting ready to get off here for a few hours anyway.

I'll check back in this evening to see how things go.
