I've been looking for something like this for a long time, something to carry in my laptop bag on the go and in my IT toolbox. This device has 3 operating modes with different uses. I wouldn't recommend this device unless you need to switch between these modes on the same device, but it does make good use of the feature. There is a client mode. This allows you to connect the device to the wireless network and connect it to the Ethernet port. This means you can connect a wired device to a wireless network. The disadvantage of this mode is that you first have to manually set an IP address on the subnet of the default Dlink IP address (192.168. wireless network. that you are connecting to. This is useful if someone is just moving a wired computer or printer, where there is no cable yet, and you just need to get it working for a while until the wiring is completed or a more permanent device is ordered.. You can also use it to connect an Xbox at a friend's house.You can use a wireless have a connection, you can have a wired connection, like in my case, just set it up for your network, plug it into your xbox and broadcast it, there are other possible uses for this mode, there is a router- mode.This allows you to share your wired internet connection with your wireless devices.This also puts them behind a NAT router with all the usual inputs positions. It's the easiest to set up and understand, just like a regular router but without the wired ports. You can login to the default dlink wireless network, navigate to the default IP address (192.168.1.50) and then change all the settings, set up security, set up a static WAN address, etc. This is useful if you want to share a dsl modem with a group of laptops, or connect the laptop to a wired network but keep it behind a NAT firewall to isolate it from inbound access from that network. I really won't be using this option very often, but as an IT pro, it's good to have a spare router in your laptop bag that you can set up for wireless clients in a pinch. There is an access point mode. This allows you to connect your wired network to your wireless network. This bypasses any firewalls/routers and uses the wired network's DHCP and all. This works out of the box with no configuration, but I would recommend connecting to a wired port with a static IP to connect to 192.168.1.50 and change the name/configure security. You don't want malicious access points giving people unsecured access to your wired network, usually even temporarily. For me this is the most useful mode. You can use this in places where there is no wireless connection. Just plug it in and you can plug in your laptop and move around wirelessly. You can also connect multiple devices. This is good if you take a hotel with poor or no WiFi connection, but with a wired connection, and at the same time use, for example, iPhone / Android Wi-Fi. Most of my clients don't use WiFi on a corporate network, so I can use it to connect and use my tablet without lugging around a cable. a little more than it should be. It has a USB cable to power the device from the laptop instead of the AC adapter, but it seems that range is reduced in this mode. The range is not as good as with a larger WiFi network. N Device with larger antenna (internal or external) No antenna connection for external antenna. There is a USB port for sharing with the Shareport utility or using a 3G modem with it, in router mode only. Each mode switch has its own configuration, passwords, default values, and so on. I recommend using a label printer to record key settings on the unit for each switch mode when changed. It supports WPS and even has a WPS button, but I didn't test that as I don't like auto wizards. The only thing I can think of as an improvement: an external antenna port, a second LAN port for LAN router mode and possibly a rechargeable battery (ala mifi devices) to run for hours without having to look for a power cable.
