I have the luxury of working from home and I need a fast, reliable wireless router with good wireless coverage. My old D-Link DIR-615 was fast enough but I was never really happy with the wireless coverage. We have a 2 story home and as long as you were on the same floor, you were OK, but the other floor was spotty at best.The other problem I had with the old router was the limited number of concurrent connections it supported. As the number of wireless devices increased in the house (smart phones, iPods, several laptops, an E-reader, the Wii... you get the picture) I started getting complaints about dropped connections and/or the router being frozen.After researching what was available and working well for others, I settled on the Asus RT-N56U. The Asus has all the features I need such as high concurrent connection limits and extended range in the 2.4 GHz band (the band I use with my work laptop).So far, I couldn't be happier. The unit was easy to setup and plugged into my home network (wired and wireless) with zero issues. My work laptop now gets 5 bar - excellent coverage on both floors of my home and we have no issues with dropped connections or router hangs.We have connected the following wireless devices to the Asus with no issues:- iPhone 4s- Motorola Atrix- Blackberry Bold- iPod touch- Epson Workforce635- MacBook Pro (uses the 5 Ghz band)- Dell laptops (Win xp and Win 7)- Nook color- Wii- Samsung Blu-ray- Asus TF300 Tablet- Nokia Lumina 900- iPhone 5- iPad miniThe unit came with an older firmware, but it was painless to upgrade to the latest. I simply downloaded the latest firmware from Asus to a PC and then upgraded the router via the admin web interface.My only complaint is the bandwidth graphs don't show traffic by device. Instead, you can see the traffic by total, wired, 2.4 GHz wireless and 5 GHz wireless.One final note. I use the Cisco VPN client on my laptop to connect to the office  and it has worked flawlessly since day 1. No changes required to the client, work or the router.Update 6/11/12Just a quick update to add a couple of new devices that work flawlessly with the Asus router. We've added an Asus tablet and a Nokia phone to our stable of wireless devices. This router still rocks and delivers consistent performance despite the growing load.Update 6/22/13Another quick update to add/change devices. My wife replaced her Atrix with an iPhone 5. The iPhone 5 supports both 2.4 GHz and 5 GHz bands. She is using it on the 2.4 band. We also added an iPad mini to the mix so the kids will let me use my Asus tablet. Even with these new devices, the Asus router is handling the load without issues! It's just a great little unit for what we use it for. 

Question: How are have multiple devices trying ?
