There is a wireless router security issue affecting all manufactures. Hackers can take remote control of your router. This can be fixed with a software update downloaded from their website. All you need to know is the model and version number listed on the bottom of the router. The version number follows the model number for example WRT54G v4. Their website will have upgrade instructions or call their support number. You can also call us and we can perform the upgrade. If your router was supplied by your internet provider contact them for more information.
