Extreme speed loss with wifi extender

[SnowMare]

So i have verizon fios and usually get 70-80 mbps in my 2.4ghz and 5ghz bands (havent tried the ethernet speeds).

I moved downstairs and so i bought a TP-link RE210 wifi extender and connected my PC to it via ethernet. Using this extender, i now get .3 to 20 mbps speed. I can run a speed test on the upstairs router and it would give me 70-80mbps and when i run the speed test using the wifi extender, i get around 1mbps. How do i fix this issue? i tried to factory resetting the extender and the router and redo the set up and same issue. did this 3 times now.

i would like to mention that in the past it used to get about 60mbps and ran fine but recently it stuck below 20mbps

1. A completely wireless extender (repeater) will halve your wifi speed. It spends half the time listening to what you're sending, the other half re-broadcasting it to the main WiFi router.

2. Upstairs/downstairs is the worst possible configuration. The WiFi signal propagates out as a torus (donut shape) from the antenna. If the antenna is pointed up, the strongest signal strength is out to the sides, with almost no signal strength going up/down. If your router has multiple antennas, you can mitigate this problem by turning some of them so the "meat" of the donut intersects your target area downstairs. If the receiving device also has antennas, it works best if the sending and receiving antennas are at the same angle pointed in the same direction.

3. Wireless is an every-changing landscape, with new interference sources popping up every day. A neighbor getting a new device, a new poorly-shielded piece of electronics you've plugged in, or an otherwise unnoticeable failure in another piece of electronics you've had and used for years could be interfering with with your WiFi causing speeds to drop. I lost about half my 802.11ac speed when I rearranged all the power and video cables behind my AV system (which is right next to my WiFi router). It is just the nature of wireless.

1. Which specific Verizon router do you have?
There is a large difference between the default ActionTec, and the better G1100 Gateway.

2. What exact plan do you pay for?
