You can tell from the name wireless router, that mean router which does not need cable for connection. Wireless router is combining of two device, router it self and wireless access point. You can find this device easily in public place such as Internet Café, Coffee shop even in hospital.
If you use wireless router as well in public place, so you can still connect to the internet every corner of your house. The things you should consider to get a new wireless router are;
The Price
This is the most important factor for buyers when buying this device, based on my experience, do not choose the lowest price in the market, because low price usually comes with below standard quality.
Technical Support
Find the wireless router that has after sales service near your town, you don’t want your end up to useless device just because you can’t find technician to repair it.
Easy Firmware Update
Find an easy firmware update and free (if possible), you don’t want to pay for the firmware update that is the same price with the wireless router you bought.
