I was looking for a short-term replacement after my old Billion died, so picked up the D-Link DSL-2878. That was my first mistake. Without any external antennae, the range on the 5GHz is very poor, even for 5GHz. While the 2.4GHz range is reasonable, the constant wifi connection drop-outs and sudden speed drops makes it useless for most tasks. Browsing the web even becomes painful when you'll suddenly suffer web page timeouts for up to a minute on and off throughout your day. The disconnections and speed drops affect a range of applications like browsing, streaming, and online gaming. If you plan on using it for your one wired PC and maybe a phone, you can find cheaper modem/routers that will do the job. If you plan on using it for any more than 2-3 wifi devices in your house, do not buy.
