Thanks console access (SSH) and opkg repository are also a variety of further options is available. One of my router now act as a permanent OpenVPN gateway, which connects my own home network and that of my family via Layer 2 Bridge with my servers. For my mom watch the media from my home server via DLNA, while I can access on the go to my documents. While the flash memory of the router for installing OpenVPN is too small, but the router has a lot of RAM, which can be used as volatile memory replacement means ramdisk. A self-written startup script will download the OpenVPN package and unpack it in the RAM disk.
Another router acts as free wireless node. Thus stands guests and my neighbors a free and fully open wireless Internet access is available, without that I have to worry about liability for interference. A BATMAN support in the kernel for a dynamic mesh routing, the availability of TC for the bandwidth limitation and the fastd for VPN connections make it possible.
The range of the router is in contrast to other routers on the market quite well. This may be due to the reasonable antennas, which have quite considerable dimensions. However, a WLAN AP is not look good, but provide WLAN. So I think this is by no means a negative point. In addition, can be via alternative firmware, the router also outside Germany operate, where necessary, higher transmission powers are allowed (up to 500mW) than that applicable in Germany 100mW. However, limited to 1 to 11 without patch the channels of alternative firmware. Approved in Germany channels 12 and 13 and the approved in Japan Channel 14 are not available, even not in the corresponding modes.
Bottom line, I highly recommend this device for advanced users.
It concerns with the WR821N (D) by a powerful router with little flash and a lot of RAM for more demanding than a 08/15-wireless access and for crafting. The low cost and high adaptability make this device an ideal gateway drug into the network technology.
