Quality router?

[432]

I have a Motorola DOCSIS 3.0 modem, but a router that is about 3 or 4 years old. Do i need to buy a new or 'upgrade' routers? Will there be a difference in internet/bandwidth strength? Like faster internet connection and download speed?

If so, what specs do I need to look for in routers? Like for modems, DOCSIS 3.0 and good brand are things to look for.
Sounds good. I have Comcast internet.

Short answer - NO.
That modem is fast enough:
Internet download speeds up to 172 Mbps and upload speeds up to 131 Mbps based on your Cable provider service
That is 21 MB/s download and 16MB/s upload.
You most likely need a better internet service plan.
