Help, is it my router or modem that is slowing down my internet speed?

Hi,

I was hoping I could get some help figuring out which of my devices (router or modem), is at fault for a slow connection.
My connection is rated by my ISP at 200Mbps, however I can only reach from 60-70 Mbps over wifi. I have a Cisco DPC3010
modem and D-Link DIR-605L router. Can someone help me figure out which one it could be?

Thanks!

The wireless speed you are getting is typical for your wireless router (300-N), here is some more info on what you can expect:

If you'd like to get higher Wi-Fi speeds, your best bet is 802.11ac router (and client adapter), or gigabit wired ethernet. That said, you can try connecting a client PC directly to the modem via Gigabit Ethernet to see what you are actually getting (you have to reboot it every time you change the connected device).

I hope this helps.

I see, I think I kinda understand. I have two questions though, if it's not too much to ask. Just to clarify it's my router that's the problem, the modem doesn't affect the speed?
Last thing would be, can older devices which connect to 802.11n over 2.4ghz get speeds higher than the 60-70mbps?

Thanks a lot btw.

Some devices can, depending on how many "streams" they support. 802.11n supports "up to" 150Mbps per "stream", you can have 1-4 different streams from the router, and there are some client adapters that support multiple streams. You'd have to have such a multi-stream client adapter to get above those wireless-N speeds.

As to your other question, the modem, and your ISP can also be the culprit, you can always test with an ethernet cable having a PC connected directly to the modem though.

I am also facing a similar issue. I am using a 60 Mbps cable connection from Acanac.
I am also facing the same issue. I am getting a slow internet on my PC(desktop). My other WIFI devices are okay (laptop and cell phone are connected using wifi ). I discussed this matter with my friend. He is a tech guy. He told me to replace some adapters related to the network from my PC. Don't know what to do with this issue.

I scanned for virus and found nothing. I thought some bad programs are eating my bandwidth

You'd have to give out more specific information if we are to help in any way..
What is your WiFi adapter model, what is your router's model, what speeds exactly are you getting from that PC, what speeds are you getting on the other clients, what Operating System, how far is the client (is the WiFi signal strong), are the other clients that are getting better speeds at the same location as the PC ?

I think you should check your modem.. most probably modem is problematic
