USB Wireless Adapter Won't Connect to Network

by Joanna498 / March 7, 2009 1:15 AM PST


I recently purchased a USB Network adapter for my Dell Dimension 2350. It is branded "EDUP" and I got it on eBay. The disc that came with it was of no use, but I did manage to get it installed on my computer. The problem is that when I go and try to connect to my wireless network (using a Motorola SurfBoard Gateway SBG900) my network is recognized through the Wireless Network Configuration tool that Windows uses, but it won't ever connect.

I'm using Windows XP with all the latest Service Packs, 1 GB RAM, basic set up.

Thanks in advance.

Does your router have wireless security enabled ?
by fihart / March 7, 2009 7:49 AM PST

If you do a scan for wireless networks in your area does yours indicate WEP or WPA enabled ?

Are you sure you're actually connecting to your router ? Lots of people leave the router SSID on default (usually the manufacturer's name) so if you have a Netgear and so does your neighbour you may be barking up the wrong tree.

The solution to all these things may lie within the usually unread pages of the router manual.

That's kind of a complicated answer
by Joanna498 / March 8, 2009 12:30 AM PST

The short answer is yes: the modem does have security.

Long answer: When I initially set up my modem, because I wanted to connect to several different machines (laptop, desktop, BlackBerry that has WiFi capability), instead of using WAP security, the network is officially "open" but will only accept log ins from certain machines via the MAC address. I have added the MAC address from the wireless adapter (found by using run:cmd:ipconfig /all) to the modem. When I try to connect using the adapter, it finds the network but will never connect.

The adapter has a light on it, a little green one, that seems to go on and off. I'm afraid the adapter might have a power issue but having never used one of these in the past I'm not sure that its normal for the light to not be on all the time.

Also, and this is kind of hard to explain, but the adapter has a sort of case and the inside seems to slide in the case so that sometimes when I go to plug it into my computer, it pushes back and then does not fully connect via the USB port.

I'm thinking the entire unit might be faulty. Sad

Try a USB extension cable.
by fihart / March 8, 2009 6:34 AM PDT

Manufacturers of USB devices don't always take account of the wide range of case designs so that some products will not plug in securely to every computer. Wireless adapters usually come with an extension cable -- or one can be bought for not much cash.

As you are using MAC ID inclusion security (which incidentally is far from safe) you might try turning that off and see if the adapter connects then.

Security is not the issue

Why would all of my other devices connect with my current security settings?

I have configured the modem to recognize the usb adapter but it isn't working. My question is: why won't it connect to the network? Not, is my current security set-up "safe"

Thanks again.

Let me be blunt.

Given the kiddie smac exploit and such tools unless you have WPA you have left the door open for such an issue.

Only those that are confused will stay confused.

Because someone else cloned your Mac address and is

connected to your network.

Watch this video and see how simple it's done.

All we suggest is to use the settings in the Forum Sticky. Without using these settings, which has worked for sometime, then your going to have problems with devices connecting. I use the forum sticky settings and I still haven't had a wireless device that wouldn't connect.

It works now.

It was not a matter of being cloned by my neighbors (who, by the way, happen to be cows and horses). It was a matter of having a mis-type in the MAC address.

But thanks for trying to make me feel stupid. I really appreciate it.

MAC filters?

We don't use them because it's broken all too easily.

Please don't feel you have to defend that sort of security.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
