Great if you set up and run DD-WRT correctly. It's been 48 days without a reboot and the Wi-Fi has been consistently strong and stable. I'm really surprised by the device, even after almost a year. Edit 4/2/15 - Still working. Got a good one judging by the reviews. I have configured 6 networks with different firewall configuration levels, 2 of which are hardwired and one wireless network is a fully isolated guest network. A recent Wi-Fi switch by my neighbors caused me some trouble, but using the scan tools in DDWRT I was able to find an unused channel and easily avoid interference. I didn't notice any significant loss in the WiFi signal either. Still an epic 5 star router for me.
