I have a Netgear R7000 router which has been going solid for years now. I was on a Zen 150/30 FTTP connection which it seemed to handle fine. However I upgraded to 550/70 last week but I’m not getting the full speed. Initially the speed was maxing out at 165/33. I found out about a bug with the R7000 which requires QoS to be enabled and disabled. I did this and also updated the firmware. Now I’m getting 330/76. Zen provide 550 down with a guaranteed minimum of 500. They say the line is fine. The speed test is being done from the router itself so that should rule out other connections influencing it. Is the R7000 just too long in the tooth now or is there something else I could try? Thanks.
