Will 802.11ac router increase download speed?

If I currently get an average of 20mbps using a linksys n router with comcast as my ISP. If I upgrade to an ac router, and assuming I have ac compatible devices, will I get any significant increase in wifi speed? I wasn't sure if I need to get a faster internet tier from Comcast or not. AC routers promise much faster speeds (400mbps) but comcast says they provide me with 25 tops. Can I just upgrade my router or do I have to pay more to comcast?

If 25mbps is all that comcast is providing, u are doing all u can expect if u are receiving 20 u are doing all u can expect with that plan. changing u'r router is not going to help in the least.

Totally agree. The ISP controls your bandwidth; your router only assists your lan attached devices to avoid lagging.
