If just used to connect a laptop and an ipad then you don't need a
router. You need an Access
Point. Most home/consumer WiFi devices are both a
router and an access
point, with the AP providing the WiFi component on one or more LANs (VLANs), and the
router component performing the IP routing function between those VLANs and an external WAN connection such as ADSL or Cable ISP. I echo the comment above that at the $50 price
mark you are getting an entry-level consumer product. Such products have their place and can be reliable and simple to configure and use.
At my main
venue, we installed a Cisco wireless
point for coverage through the main
auditorium for tech work (iPad control of the Midas desks with Mixtender App, wireless control of the Vista T4 lighting
console etc), which is separate from the regular WiFi
network that provide guest and secured LAN connections to the campus
network. But for
portable use where I just want to connect my iPad to my LS9 to use StageMix I have a couple of really cheap, very simple wireless devices. I picked them up in Hong Kong (Wan Chai Computer Market) for the equivalent of about US$30 each. They are powered through a Micro-USB port and can operate as a WiFi
Router or AP. Comes in handy in a hotel room as well for converting the single wired internet into my own personal WiFi
hotspot for my laptop, iPad, iPhone/Blackberry
etc.
So its really about selecting the right tool for the job. If you want solid, reliable and good vendor support, then you may need to look at a higher price
point. If you want good value and are willing to accept the associated risks, then you can certainly achieve your goal in the price bracket you are seeking.
But remember all you need is an Access
Point and you may be able to save some cash or step up to the next
level of product by sticking with an AP rather than a
Router. But do be aware that there are two types of Access Points - Autonomous and Light-Weight. Those known as "Light Weight" APs are generally cheaper but require a controller in the
network and are designed for multi-AP installations, so they are not what you need. Some can operate as either Light Weight or Autonomous depending on a software license installed. If going for an Access
point, make certain its an Autonomous AP and not a Light-Weight AP.
