Xfinit and Product Model: C3700 internet speed issue

came across same issue. seems like the c3700 can only handle upper 90s. hardwired through comcast/xfinity i got 94 and only 10 max on wifi. fricking garbage. when i was in a home only buying xfinity wth 75 mbps my net gear got me 80+ and wifi 30+  i dont understand this. but to get the 150 im 99% sure this modem wont reach that speed. but if i dowgrade my internet to 80 i have to drop xfinity channls which makes no sense. going to ook for the best modem on the market toavoid the ten dollar a month charge.
