A little of my experience on the Amped Wireless R20000G
Intro: The R20000G was extremely easy to setup. 3 steps and in 2 minutes and I was online. It took another minute to configure my WiFi preferences and another for the router to reboot to complete that. All done in 5 minutes. The setup wizard is very well written and detailed.
Wireless performance: I got very good performance throughout my odd mixed construction house. My house was built and renovated through the 1910s the 1970s and a few years ago and it's always a construction zone with materials ranging from thick plaster to drywall for the walls, lots of metal used in the dropped ceilings with fluorescent lights, thick staircasing, thick floors in some areas, and I got big metal doors. I get solid 5 bars within the confines of the house (1800sq ft) and 4-5 bars 34dBm @ 100% on my back porch and at the mailbox across the street I get 4 bars. I can even walk 100 some feet down the road and still stream videos in HD! I can walk around 200 some feet away and play SD videos. Reading for that: 225ft down the road from the R20000G about 3-4 houses down -67dBm @ 86%
Please note: These readings were taken with the Amped Wifi analytics tool from Google Play.
Xbox Live Performance: No disconnections! They played Dead Space 3 for 4 whole days. Also on Black Ops 2: Zombies the performance was excellent... maintained full green bars through hours of play! Both Xboxes were wireless.
USB Performance: Transfer rates were around 3.5-4.5MBps within the LAN and the same over the WAN.
