I'm using windows 7 with a wireless rca by thompson dcw725 router. my desktop is wired into it, but i got a laptop that connects wireless, but has no internet access, says limited connectivity. Any ideas...


First of all, you need to check if the laptop is correctly connectedto the router.
try the following steps to see if you are effectively connected to the router :

1. Open the command prompt on your desktop computer (Start -> All Programs -> Accessories -> Command prompt OR Windows Key+R -> type cmd).
2. Type ipconfig /all and then note down the value given for Default Gateway
3. Repeat the first two steps on the laptop and compare the values of Default Gateway.

If the values are different, then it means the laptop is not correctly connected to the router.
You will have to delete the Wireless network configuration (In the Network and Sharing Center, you will find it in "Manage Wireless Networks").Then start the wizard for connecting to a wireless network. Be sure that you enter the network security key correctly.

If the default gateway values are correct, check the firewall/antivirus settings on your laptop. If you cannot or don't know where to look, deactivate them completely and try again.
You may also need to check the parental control settings and your web browser settings (notably if it is in offline mode).

Last but not least, on the laptop, delete all broadband connections and/or dial-up connections that are present (in the Network and Sharing Center, go to "Change adapter settings" to find any broadband or dial-up connections).

My Atheros AR5007 will only complete a "Local Connection, No Internet Connection" to a NetGear N600 Dual Band Router when Security Options (WPA2-PSK (AES)...ect) are selected on the Wireless...


Since the connection works without the encryption settings, it is NOT a driver issue. It sounds like a missing wireless network security setup problem. So assuming Windows (Mac OSX is similiar):

  1. Connect a laptop/PC to the NetGear via ethernet. It saves on some aggravations later.
  2. Connect to the NetGear and restore the security settings, and remember your keyword.
  3. On your computer, open the list of Wireless Networks (usually Start->Control Panel->Network(ing)->Wireless Networks). The menu sequence might differ slightly, depending on which Windows you're running.
  4. Find and click on "Manage Wireless Networks" (or words to that effect)
  5. Right click on your wireless network's name to get the drop down menu, and select "Properties"
  6. Find a button or tab related to "Security"
  7. Under Security Type, select WPA2-PSK (or Personal)
  8. Under Encryption Type, select "AES"
  9. Under Password (or Security Key), type in your router's WiFi security key word. You may have to log back into the NetGear and find the keyword (yours) or the alternate (gibberish) form.
  10. Save the settings
  11. If you're connected to that wireless network, then disconnect
  12. Try connecting to the wireless network again. It should work this time.

Do home copy machines like Epson inkjet models have hard drives that could possibly create a security breach if they were stolen?


No inkjet based machines past or present contain hard drives. They present no storage security risks. The only possible risk would be access to the machine via your network from an outside source. The only data that could be accessed would be fax numbers, names etc.
This would require a major security breach of your network however, and is highly unlikely.

Internet Explorer cannot display web page


a couple things I've seen
- first the address as posted is invalid (can't find) but if you insert a dot (.) between parents and brickshools then it finds it (http://parents.brickshools.org/)

- if the corrected address is correct it looks like the site is redirected to a secure connection (https vs. http) and then the problem is that the site owner's security certificate has several problems as follows:

The security certificate presented by this website was not issued by a trusted certificate authority. The security certificate presented by this website has expired or is not yet valid. The security certificate presented by this website was issued for a different website's address. these issues were presented to me by Internet Explorer v7.0 - the main address functions (http://brickschools.org/) so it definitely seems to be a security certificate issue on their end. I would speak with the site owner. btw, I'm coincidentally in Toms River :)

You may want to look into this. This may be your issue with AVG anti virus. The Conficker worm mostly spreads across networks. If it finds a vulnerable computer, it turns off the automatic backup service, deletes previous restore points, disables many security services, blocks access to a number of security web sites and opens infected machines to receive additional programs from the malware’s creator. The worm then tries to spread itself to other computers on the same network.

Need help setting up a secure network.


Go to 192.168.0.1 in your browser, log into the setup page of the router. Under wireless set the SSID(network name), click apply, then go to security and set the encryption key, Click apply and log out. Then on your computer, if it is wireless, click on the wireless network icon, the when it shows your network, click connect . Then you have to put your encryption key in twice.

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe
