By error I uninstalled Etheros AR5007EG Wireless Network adaptor and now I get Code error of 80246005. I want to reinstall the driver or fix the problem as I cannot get connected to wireless internet

I believe your question is how to uninstall and reinstall the nic.
Go to control panel->system->hardware->device manager
alternatively type devmgmt.msc in the run dialog box
click on the plus sign infront of network adaptors right click on the network card present click on uninstall. You will get a warning that you are about to uninstall this device from your system, select OK and once that device is gone restart the system go to the action tab on the top in device manager and select scan for hard ware changes the network card would be reinstalled automatically.

if you can get access to the internet on another computer the above link gives useful info on troubleshooting error codes generated in device manager. If you can't get online try highlighting the device in Device Manager and right click for a list of options>click on update driver. If that doesn't work uninstall the device and windows should recognize and reload drivers for it when you reboot.

u have to reinstall it driver to update it. Or maybe u have different wireless driver on your system. U have uninstall any third party driver.

Uninstall any and all "Norton" application from your computer using the "Norton uninstaller". Then reinstall the network adapter drivers.
The norton firewall causes a HUGE LOT of problems to the network adapters.
Get another security solution, other than any "norton" product.

try to reinstall the driver for the wireless adaptor on your notebook..then try to connect again..then rescan your laptop for virus also...hope this helps...ITTech7574

uninstall the linksys software / driver. reboot, plug-in the adapter, when windows asks for the driver put in the linksys disk and let windows find the driver. (Do not install the linksys Connect software....). This will fix the issue.

Its driver related. Uninstall the driver and reinstall automatically (via windows update)

Try to check on the device manager if the wireless adapter and the ethernet adapters were installed properly. If it appears with a questionmark, uninstall it and try reinstalling it without the ethernet cable connected.

If you are using Vista system, after installing the adapters, go to the network connections and just click on tcp/ip then click on properties. Exit from the window by clicking ok until all windows will be closed for the network connections. Reboot your pc and try if you can obtain a connection.

well i think u check the My Computer. After that, double click on Device Manager, then u will see Acer Aspire 5315 or not. If not then reinstall that again or check Program Folders
