Wi-Fi Extender Internet Connection Cutting Out.

We have an Arris TG1682G router in our house, and I am connected to it via a TP-Link Wi-Fi Range Extender. I'm plugged into the extender through an Ethernet cable. We use Bright House.

My problem that I'm having is that when I am playing an online game, every once in a while my internet will cut out and back in for a few seconds, which in turn disconnects me from my game. Not a lag spike. My internet actually fully cuts off for 5-10 seconds and I will get disconnected from my game. This will happen once every hour or so when I'm gaming for longer sessions.

I've tried several things.

1. I've tried connecting to my extender's network with a Wi-Fi adapter instead of Ethernet.

2. I've tried completely changing to a different Wi-Fi range extender. (Netgear Ex6100v2)

3. I've tried resetting my range extender.

4. I've tried connecting to both the 2.4 GHz and 5 GHz networks individually.

I don't think it's a problem with the router because my roommate's internet seems to work just fine from his room, which is only slightly closer to the router.

I have my Wi-Fi range extender in my room because there are no outlets between my room and the router that I can use. I just use it because it basically acts as a faster Wi-Fi adapter.

Another thing I've tried is just connecting directly to the router using my Wi-Fi adapter. Still get the same problem.

I get really good internet speeds other than that one issue though, and I get no lag or anything in between the drops.

Additionally I am running Windows 10 on a desktop PC.

Any suggestions or help would be much appreciated.

Thanks!
