I have owned a netgear nighthawk R6700 router version 3 for the last two years. My IPS provides 100Mbps down and 35 Mbps up which I receive in full on the 5ghz channel and hardwired. On the 2.4ghz channel I might receive 1/10 (or less) of that performance. Once I re-boot the router the 2.4ghz performance goes back to 100/35 Mbps performance but after several days throughput drops back to 1/10 of the standard performance until I perform another re-boot. I have not added any new clients to my network in years. Anyone have any ideas to the issue?
