Upgraded from 350 to 1Gig, yet the speeds were better when i had the 350? Using Wired i get anywhere between 300-700, Realspeed is currently saying that only 400 is going to the router. Wi-Fi, near or at a distance from the router gets around 20Mbps, (On 2.4) 70-200 on (5.0). Any ideas on the issue, and maybe a fix?
Could you access your router using http://192.168.0.1/ or http://192.168.100.1/ for modem mode . Don't log in, select the 'Check Router Status' option and paste your 'Downstream', 'Upstream', and 'Network Log' tabs?
At least we can check the stats to rule out an issue with the line.
