My landlord has wifi for all the apartment units. I just installed a new motherboard and memory in my computer myself and got the computer running fine, but I can't figure out how to connect to the internet. There is an icon in the system tray that says "Local area connection 2. A network cable is unplugged". I have never used wifi before. I was using DSL before now. The antennae is marked "Trendnet TEW-645UB", and I have it plugged into its base and the usb plug connected firmly to my pc and have tried different usb ports. When I started up my pc for the first time after installing the new hardware I got messages from I believe my Comodo firewall warning that "Realtek.exe" or something like that was trying to install programs. Since Realtek is not the name on the wifi antennae I chose to not allow the programs to install. I turned off Avast, Comodo, and the Windows security and tried to connect to the internet to see if they were blocking something, but I still couldn't get on the internet. When I go into control panel there are several Realtek program icons shown. I have XP Home on my computer and use Avast scanner version 5.0.462 and Comodo firewall version 3.13.121240.574. I'm sure these are outdated because my computer has been in storage for a long time.
Under Device Manager there are yellow question marks to the left of "other devices" and "802.11nWLAN". At the bottom of the list there is a yellow exclamation point to the left of "unknown device". In Comodo under "DEFENSE +" "Application" There are eight "C:\WINDOWS\RTHDCPL.EXE\" listed on the left with the date 4/12/12 to the right. There is nothing new under "view firewall events" or "my blocked files".
I found the Trendnet cd and installed the utility. I then connected the antennae to the usb port as the instructions said. The quick install guide on the utility cd said that after connecting the antennae to the usb port that these messages would come up: "Found new hardware wizard" then "Install the software automatically" then double click on the wireless client utility in the system tray then "site survey" is supposed to come up then in "site survey" I am supposed to select "ssid". None of these messages came up even when I restarted the computer with the antennae connected to the usb port. I tried a few different usb ports. When I double click on the wireless client utility in the system tray this message comes up: "802.11 Wireless client utility" and under this in the same window: "The adapter is not present" and "ok" beneath that. This same "802.11 Wireless client utility" message pops up everytime I start my computer. Since the message "Found new hardware" never pops up and the "802.11 wireless client utility, the adapter is not present" does pop up does that mean the antennae is bad? Thanks for any replies.
