Why can't my DLink DWL-122 USB adapter not find the wireless network even though signal strength is excellent?

Question

I purchased a DI-524 router and DWLG-122 USB Wireless adapter togther and was able to set up the router easily. I had no problem picking up the wireless signal on my laptop anywhere in the house, but when I attempted to install and use the USB adapter it will not work.

I've installed the latest firmware update, but it still reports that it cannot find a wireless network, even though my laptop is sitting right next to it and reports that the signal strength is excellent.

I've uninstalled and reinstalled numerous times without ever having the USB adapter pick up the signal.

The people I've talked to on the tech support line were very difficult to understand and I have a hard time believing that this can be that difficult as it should be a straightforward plug and play type of solution.

I have not changed any factory defaults so I'm thinking this may be a hardware failure. Any help you can offer would be most appreciated!

Thanks for the replies so far. I'm running XP Pro w/ SP2. I've tried connecting using both XP's Wireless Config and w/ the D-Link config w/o any success. It's not even getting "seeing" the network, let alone configuring it. The D-Link utility icon is just white bars and it's bombs almost immediately when I search for wireless networks. My laptop saw it and connected immediately right away so it can't be signal strength or encryption. My next step is to borrow a different USB adapter from a friend who no longer uses theirs to see if that would make any difference. I don't think it's firewall related as it doesn't even get that far along in terms of trying to connect to the net.

Answer 1

After installing the 122, and of course the drivers, did the little green (or yellow) D show up in the system tray? Are you using win XP? If so, make sure XP is not grabbing the wireless device and trying to establish a connection. I've had that trouble before. (You can tell windows not to manage your wireless connections in the network properties.)

Once you've made sure that's the case, make sure the 122 is configured for infrastructure mode and that it's not already configured with a network. What does the site scan show? Anything? If not, then without being able to determine any thing else, I'd say perhaps a HW issue.

Check your firewall. 9 out of 10 times, that's the problem. You have to add the IP address of the router (usually 192.168.0.1) to your firewall's trusted zone.

To check to see if it's a problem with your firewall, open a DOS window (Start > Run, type in CMD and click OK). Type:
ping 192.168.0.1
If you get a "Request timed out." then your firewall is probably blocking the router. You can also check your firewall's alert log to see if that IP address is listed in the events.

I used to have a similar situation, i ought to unplug the router wait a lengthy time period and then reconnect, if it nonetheless would not artwork then unplug the router, shutdown your workstation to restart each thing and reconnect router. once you've Comcast, get their butts on the phone because we are paying too a lot for it besides. I did the above, verify the cable connections and ultimately offered a better moderen router that has prolonged instantaneous B/G/N decision. solid success. -CM

it says the signal to the network is excellent, it doesn't mean to the internet.
