cable router speed?

post #1 of 8
Thread Starter 
is there any difference between an old cable router and a new cable router? say you have the fastest internet available from your company today. would an old router limit the speed of that internet vs a new one? are there any new routers that would still limit that speed? if so, which router can maximize the internet speed by cable as well as by wireless? im not really sure what to look for

Yes, an older modem would limit your speed. They have DOCIS 2.0 that really doesn't get above 15mbps. The newest is DOCIS 3.0.

I am assuming you have a cable modem/router. If your router is separate from your modem then your modem is the determining factor.

Both, really.

If your router isn't fast enough to route X amount of packets you may have a limitation when they're being routed to the LAN
If your modem isn't fast enough to xcode data for X amount of packets, the data will only be hitting the WAN side of the router as fast as the modem can support.

You can usually check a router bottleneck by connecting a host straight to a modem and performing a speed test. If there is a wide variance between direct connect and utilizing a routing device, the device may be failing/defective or outdated. If it's consistently far below the speed package you pay for in both configurations, the behavior would be more indicative of the modem itself.

If you're currently getting the rated speed from your ISP, you really have nothing to gain by purchasing new equipment.
