Situation is, I have ATT fiber and the router is forced to be downstairs while I’m on the second floor.

I tested my moms laptop downstairs and her speed is great. However my iphone with me upstairs is also pretty solid routinely getting 100+ mbps.

What is causing such a drastic drop in speed?

I have this PC and hardware:

10/100/1000 Network

• 2.5GbE LAN
• WiFi 6E 802.11ax

My meantime solution is I have one of those ethernet adapters, which smooths out my mbps to about 40-50.

but I would much rather have 200-250 or at least 100 mbps like my iphone.

What could be causing the drastic loss of speed?

​

Would something like the amazon aero help?
