Check the router settings, go and change the wireless channel (it could be that it is congested), also consider restart the router to factory defaults (copy all the ISP values before so you can configure that later).

If rebooting or adjusting the antennas on the router does not affect the problem, and the router works fine for your roommate, what makes you think the problem is with your router?

Your symptoms are consistent with (1) failure of your wireless network adapter or its driver, (2) failure of the WiFi on your router or a new external RF source which is interfering with your WiFi signal, or (3) malware on your computer which has redirected your Internet through a slow proxy site overseas. They do this so they can eavesdrop on your encrypted network communications like online banking sessions.

Connect the computer directly with an ethernet cable. If the speed is still slow, then you need to run the usual anti-virus and anti-malware scans (Malwarebytes). If the speed is fine with a cable, then that eliminates (3) as a possibility. Try testing the Internet speed with a different WiFi device like your phone.

If the phone works fine, then (1) is your likely problem. Try uninstalling then reinstalling your WiFi network adapter drivers. If that doesn't work, try a different WiFi network adapter.

If the phone is also slow, then (2) is likely your problem. Try borrowing someone else's WiFi router for a few minutes to see if it fixes your problems. Try changing channels on your router - 1, 6, and 11. You can skip the other channels as they overlap. Unfortunately your router only supports 2.4 GHz. This frequency is very crowded and is subject to interference from all sorts of things like microwave ovens. You may not be able to find a clear channel, especially if you live in an apartment. If your devices support 5 GHz, you can try replacing the router with one which supports 5 GHz.

Try uninstalling then reinstalling the drivers for your WiFi adapter (to reset any settings which may have gotten borked in the registry).

If that doesn't work, update and run anti-virus and anti-malware scans. Some malware will prevent you from downloading or updating Malwarebytes. If you run into that problem, download the latest version on your brother's computer, copy it to a USB drive, and install it on your computer.
