Slow Wifi, Tried Two Routers

Hey guys,

So I recently upgraded my Cannatel speed to 300/20 from their $40 promo. When I'm wired in the speeds work as advertised. But on wifi I'm barely breaking 100. I tried two Tp-Link routers (C20 and C50) and tried adjusting the settings like channels manually but nothing worked. What am I doing wrong here?

I assume you are on 5 Ghz instead of 2.4? Maybe you are on a congested channel?

Have you tried more than one device to test your speeds? If not, do that first. Ideally, with something that isn't similar to your original test device (so, don't use your iPhone 10 ... then also test with your wife's iPhone 10).

If you can test with more than one device, and the speed issue still exists, then it basically has to be those routers (or your configuration, somehow).
One who is offended by truth, has no place among those who seek wisdom.

What device are you testing your wifi on?

Your expectations are too high. Reality is that WiFi is subject to so many variables that you should probably count yourself lucky to get a consistent 100mbps if you're not in the same room with the router and using a device with multiple receiving antennas.

Meanwhile, 8 neighboring households have also tried 2 different wireless routers each and they're also scratching their heads as to why the wifi is slow....

Try testing your wifi at 3am in the morning. And hope that your neighbor isn't downloading porn at 3am.

You need to be on at least 5Ghz N wifi to get close to or over 100mbps, but if you want 300mbps on wifi you will need a 5Ghz AC wifi router.

I've done tests on my ASUS AC 5Ghz router and it was able to obtain around 300mbps upload speeds and atleast 500 mbps download speeds with no problems.

From the specs at the TP-Link site, the C20 and C50 ethernet interfaces are only 10/100, so you will never get more than 100. You need a wireless AP/router that has a gigabit interface.

This is what it advertises for the C50, "Simultaneous 2.4GHz 300 Mbps and 5GHz 867 Mbps connections for 1200 Mbps of total available bandwidth". I started a similar thread a couple of days ago with very similar issue, I'm using the C2600 though, which is suppose to be 1733 Mbps using the 5Ghz band, but I'm getting around 100Mbps.

There is a limitation for this C50 router from tp-link, "1 10/100Mbps WAN Port" means that accessing internet from ISP will be hard capped at 100mbps. Doesn't matter if you used a wired connection or a wireless one, unless you connected directly to the modem instead.

Ah, I missed that. That explains OP's situation as dmyvr had pointed out.

In practice, You will not find many devices that can access 800+1733 bonded channels. Thats why your speed is still limited to 100Mpbs.

On the 2.4GHz side, altho the router manufacturers advertise HT40 Speeds, In practice there is severe limitations on the use of this. Same for UHT160 on the 5GHz band. Hopefullt as AX band routers become more common and devices start retaining , this will be better. ( 4-5 years ?)

5g. I tried switching between different channels on the TP link router settings
