C7000 Blinking lights

Hello,

Yes i have tried. Signals especially 2.4GhZ is horrid. i sent a image in of a speedtest in my back bedroom where it got litteraly, 7MBps down and 1Mbps up. yet earlier it was 42Mbps and 16Mbps. Walk closer to the router, it will improve some, yet not by much. This house is 1,200 Square feet, single floor so its not like its far away. My speeds here asre 300MBps down and up to 50 up.  Real world, wired side im seeing wired side 330Mbps down, 30Mbps up based on last speedtest done. yet wirelsssly, not even close to those numbers on both bands.  Clients that previously worked without fail for yerars, now buffer and stop stating connection error. Its really bad.  Line checks show all good, power shows all good. yet whats happening is real.  You cant go from great clients, to the day after C7000 to bad withiout pointing fingers.  i also told the techs, the firmware i beleive to be the issue. All of what i stated to you occured after a day or so when my ISP pushed out the .18 firmware. My brother is seerign the same behavior,  great signals day 1 and then partly into 2 then .18 dropepd and signals went from good to horrid.  No amount of channel surfing eleviates the situation. And of course i cant downgrade firmware as the ISP is incontrol of that in the combo unit.  

anwyays, thats where i am at right now. Holding out for a firmware update, yet as time goes on with no clue of when that will happen and clients running really bad I dont know if i cant wait. if i bought the standalone Nighthawk I could control the firmware on my own, downgrade, upgrade at will.  Unforunetly that is not what i can do with this unit.  

Thanks.
