RTL8187 USB wifi antenna cannot connect to the internet
I have an acer x3400 desktop - no wifi card. I installed a 6db gain usb wifi antenna. Everything looks good but...
I cannot connect to one of the local networks - It is WPA preshared key TKIP/AES
The realtek wireless lan utility never gets an IP address despite excellent signal strength. I have an acer netbook running xp with built in wireless connects perfectly.
There is a second local network that is not encrypted. I have connected to the system - acquired IP address, Subnet mask and gateway. Network and sharing show the connection PC to Network, but no connection to the internet. My netbook does not have enough gain to access that network but I am sure that it is working fine.
The initial firewall setup was using Mcafee. Mcafee wouldn't let me in without an internet connection. So I uninstalled Mcafee. I have disabled the windows 7 firewall.
I have tried to connect using the Realtek utility and with the windows 7 wireless network connection screen.
media state ... media disconnected
connection specific DNS suffix ... blank
description ... Realtek RTL8187 Wireless 802.11b/g 54MBPS USB 2.0 Network adapter
physical address ,,, 00-0F-11-07-00-1C
DHC enabled ... yes
autoconfiguration enabled ... yes
Device properties indicates that it is working properly.
such is life - Any ideas?

You did right to uninstall it, McAfee is pretty bad at handling network connections.

Or we can try another approach.
First thing to do is to open up Control Panel and then in to Network and Sharing. If your control panel has been left at the default view (Category) this will be in Network and Internet. The top option is Network and Sharing Center. Click it.
If you've set your control panel to either small or large icons though, then we can just head straight in to the N&S Center without delay.
In here we can view a whole slew of information about our current connection, but forget half of it because it's about as useful as hiring a dead hooker in a mafia den if the adapter can't talk to the router in the first place.
On the very left hand side you should see Change Adapter Settings. Click it and let me know any icons for network adapters it displays. Or screenshot it; either is good but pictures speak a thousand words per minute and type even faster.
