My laptop had no problems untill yesterday connecting to the internet.
My Accesspoint/Router is Linksys WRT54g and my adapter is the Linksys
WPC54g. It associates just fine but cannot access the internet. If I
swap out the adapter for the Cisco Aironet 350 I have no problems
accessing the internet. If I swap out for a NIC and connect to the
D-Link Wireless Bridge, again, no problem accessing the internet. What
gives? I removed and reinstalled the software and drivers and rebooted
the Accesspoint to no avail. My operating system is Windows 2000 pro.

Have you tried powering off the PC, then the wrt54g, then the modem.
Then take a short break and power on the modem, then the wrt54g
and retry.
Are you getting an IP address assigned?

Taking a moment's reflection, Marty mused:
    Have you disabled Broadcast SSID?  If so, try re-enabling it.  Try
changing your wireless channel (1, 6, and 11 are best) as someone else may
be broadcasting on the same channel.  If they are hiding their SSID, you
won't see them.  If you are hiding yours, they won't see you.

I did not change anything on my accesspoint/router. One day my laptop
with the WPC54g simply would not connect to my internet - associates
but no internet connection.

If someone is using the same channel, why would the Cisco 350 and the
D-Link 810 be able to connect?

    Possibly because they have different logic that is better equipped to
handle channel overlap interference.  Try changing the channel, and see if
this corrects the issue with the Linksys.

I had a similar experience with my WPC54GS card.  I have Win2K Pro on my laptop, befw11s4 router/access point, static IPs, no broadcast, channel 11, wep 128 bit encryption. It appeared as though it was getting an internet connection right at startup, but lost it once all of the startup apps/services finished starting.  I uninstalled the drivers, removed the adapter and rebooted. I installed the Linksys drivers and then rebooted.  I shut down, installed the adapter and booted. I had to then edit the default profile to use my static IP and gateway/DNS IPs as well as the WEP 128 bit encryption settings. The Wireless Network Monitor/configuration utility provided by LinkSys is goofy, I had to put in the IPs a few times before they actually saved. I also changed the fragmentation and RTS thresholds to 2304 (through device manager, advanced network adapter properties) to match the setting on the access point.  Finally seems to be working properly. I don't know what the problem actually was, but that's what I did before I got it all to work.  I had a work-around up to now -- when the access point was found but no internet, I went into device manager and changed the channel to a different, random channel.  Applying this seemed to reset the adapter and allow it to connect successfully. Hope this helps, sorry if it doesn't. Good Luck, Tym. -- tymk brought to you by http://www.wifi-forum.com/

hi,
i have a wpc54g on a dell latitude cpx h500t with win 2k pro.
the ap is a sohoware wla-660 with 128bit wep enabled.
i can connect just fine(associate and connect to the net). i am usin a
linux box as a natted router.
i would suggest that you do the following than just repeatedly
reboot/power cycle your various devices.

a) how do you come to know that the wpc54g is associated?
the wpc comes with a utility that sits in the system tray. whenever the
machine starts up or when i eject and insert the card, i can click upon
the icon in the system tray to bring up the configuration utility. It
has three main tabs. the starting tab shows link information. It should
say infrastructure with the signal strength and link quality bands
showing adequate green bands. (try it by moving as close to the wrt or
your ap as possible).
If you do get the green bands then click on the button called 'more
information'. this shows the various network specific statistics. my
link info reads "state: connected ssid: outbackwifi channel: 6
security: wep network type: infrastructure ip address: 192.168.0.20
subnet mask: 255.255.255.0 default gateway: 192.168.0.1 dns:
202.144.115.4 mac address: mac-address-of-my-card"
It is pertinent to note here that my access point does not have a
built-in dhcp server so i gave my card a static ip address in the
network settings box. if you are using the wrt, then you should enable
dhcp to make life less complicated

b) if you dont get a similar output , then you will get a message
"unable to connect to AP".
c) Now click on the tab that says "Site Survey".
d) here you will get a table and two buttons that say refresh and
connect at the very bottom. click on refresh if you dont see the ssid
of your access point. if you do see it, then click on connect. if you
had enabled wep then it will pop out a dialog box that will ask you for
the wep key (pass phrase or the hex key), static ip address (you can
leave it at auto) etc.
e) if your wep settings are correct, you should get associated with the
access point. if your dhcp server is up and running then you should get
a valid class c ip address.
f) I would also advise you to start a command window by typing 'cmd' in
your run window. in the black window that appears, type ipconfig /all.
if you see either 0.0.0.0 or 169.154.x.x as the ip address then you can
safely assume that your dhcp server isnt working and you need to set a
static address in the same range as the lan portion of your wrt router.
phew! that sure was long and i sincerely hope it worked!
