I have 2 Windows 7 Laptops. One of them works fine, but the other as of a few days ago and for no apparent reason is no longer identifying any network I try to connect to. When I turn on the wireless adapter -- a built in Realtek RTL8187B Wireless 802.11 b/g 54Mbps USB 2.0 Network Adapter -- it gives me a list of available networks.
When I click on one of them is gives me the loading bar, which shortly disappears and if I click on the bars at the bottom right of my screen it says that I am connected, but it is Identifying and I have no Internet access. Then it stays the same for at least an hour, that is longest I have let it sit and it never changed. It did do the Identifying before, but it always identified it after not too long and then I could do whatever with it.
I have looked on many websites, including several threads on this one, and tried many solutions -- such as re-installing the Realtek driver and using the route DELETE command -- but it still will not work. By the way, in case I did not make it clear enough in the preceding, I am not a computer expert, so I would be much obliged if you would try to make your answers as dumbed-down as possible. Again I have Windows 7.
ifpconfig /allif it has DHCP or Internet; then also look if data is sent as well as received in the connection's properties and if so do a low level packet trace with Wireshark. Good luck! If all else fails, you might want to try step 12 and 13 I posted here... – Tom Wijsman Sep 25 '11 at 20:55ipconfig /allwithout thef. Pay notice to the IP address you received there, if it starts with 169 then DHCP is not working properly. Try manually configuring a static IP in that case... See a detailed explanation. – Tom Wijsman Sep 25 '11 at 22:29
