I am experiencing an issues with my 1st 5g channel on this router. I have had it for just over a year and has been great. Today, the first channel is virtually unusable 2nd channel is ok, along with 2.4 I have latest F/W in the router and have of course rebooted it, etc... Any ideas? I sure hope this expensive router is not taking a dump on me.
What actual channel are you using? Have you tried changing it?
Also, try setting your speed from "up to 4800mbps" to "up to 2400mbps", it'll change the channel width and if interference is causing your issue, it can help with that.
