Possible to turn of wireless function, but keep Ethernet function?

Approx. 6 months ago, I bought a WiFi Extender (Model: WN2500RP) and all was well. Until the signal, allegedly, interferes (?) with out main router. I do not understand how it is possible, but my stepdad spoke to our ISP, and he had to change the password for the internet (so that I would not use my extender) and test his speed and stuff that our ISP told him to do.

IF what your stepdad did was change the password for the internet, it would have no effect on your extender, however, if what your stepdad did was change the encryption key for the WiFi (which some people sometimes refer to as the password), then your extender would not be able to connect - however - if the extender was still powered on, it would still be transmitting, and the signal would still be interfering.

I'm going to suggest a few tests - starting with turning off the extender - and then using the OOKLA speed test (speedtest.net) on a computer downstairs to see what sort of throughput you get - obviously with the extender turned off it cannot be the source of interference.

The next test would be to turn the extender, and leave all of your wireless devices turned off - which should mean that nothing is using the extender - and repeat the speed test - if there is a significant drop in performance, that would suggest some sort of interference.

If there is no drop in performance, turn on your devices one by one, and test after turning on each one until you find what causes the drop in performance.

It is entirely possible that the problem is not interference from the extender, but rather the quantum or amount of network traffic that you are utilizing - the ISP will limit the bandwidth available based on the contract, and if you are a heavy user for streaming or torrents, this will have an impact on what is available for other users.

The speed test mentioned earlier will give an idea of how fast the ISP connection is, compare that (if you can) to what your stepdad is supposed to get, make sure he's getting it.

I'm now hoping there's a way to turn the WiFi function off, so that I can just use my Ethernet connection. What sucks about that is that I get **** speed on my phone and other devices in my room. Please answer, I greatly appreciate it.

If you have an Ethernet connection to your room you can replace the extender with a network switch which will not have WiFi - this might help if the problem is actually interference, but will make no difference if it's really about the bandwidth.
