Hi all, I just recently moved into a new house. We set our computers up side-by-side, literally 4 feet apart, and my computer has excellent (enough) Wi-Fi speeds and signal strength. Hers is pitiful. I've replaced the ISP router with my own ASUS router, connection is stronger but actual speeds are still crazy slow for hers. I've removed and replaced the antennae on her motherboard. I've reset network adaptors, disabled and re-enabled drivers, flushed all wi-fi and internet settings via command prompt. I'm so confused because she has strong connection to the router, but around 10 mbps download speeds or less. For reference, my computer gets 400 mpbs routinely.

I'm just at a loss. Is this related to her motherboard hardware? The router? The position of her computer? (It's only 4ft from mine!!!) Anybody else dealt with something like this and saw it resolved? I'm thinking our only fix before I run ethernet up here is a new pcie network card.

EDIT: Just ran speed tests, both computers have "strong" signal to the router.

Her computer got .60 mbps up, 1.3 down.

Mine got 200 up, 190 down.

UPDATE: Tried all the suggestions in the comments, swapping my network card into her rig corrected the problem. So I've narrowed it down to the network adaptor in her motherboard. She says she didn't remove the antennae during the move she they may have gotten damaged.
