My wife and I noticed over the last several weeks our E3000's 2.4GHz radio was spotty, typically fixed by a reboot of the router or cycling the wifi off/on. It's now a the point it just flat out won't work. I reset NVRAM and couldn't connect to even the default "wireless" SSID. The 5GHz radio appears to still be working just fine, as my desktop and iPad can connect to it no problem. Has anyone else experienced this where one of the two radios dies before the other? How about on a router that's less than a year old?
